Tkeycoin — security, that’s what we’re betting on

Tkeycoin — security, that’s what we’re betting on
Today we will talk about the security of using the Tkeycoin platform and the TKEYSPACE mobile blockchain wallet.
Tkeycoin is a peer-to-peer payment system based on p2p principles and the concept of electronic cash. P2P technology is a fairer means of mutual settlements between users and companies around the world. Modern payment systems are imperfect and may depend on the will of high-ranking officials.
We approached the market from an economic and scientific point of view, borrowing the best from Bitcoin, Ethereum, DASH, and other alternative currencies, mixing modern concepts and building on the global experience of IBM, Microsoft and a number of other companies and research.
The Tkeycoin blockchain is protected by various mechanisms that include advanced cryptographic methods and mathematical models of behavior and decision-making. Blockchain technology prevents duplication or destruction of digital assets.

In addition to providing security and recording transactions in registers, cryptography also plays a role in ensuring the security of wallets used to store Tkeycoin. Paired public and private keys, which respectively allow users to receive and send payments, are created using asymmetric encryption or public-key cryptography. Public keys are used to generate digital signatures for transactions, which allows you to authenticate ownership of the coins being sent.

https://i.redd.it/95yuky0tntx41.gif
The asymmetric cryptography architecture does not allow anyone other than the owner of the private key to access funds stored in the cryptocurrency wallet, so these funds are kept safe until the owner decides to spend them.
In simple words, in the Tkeycoin peer-to-peer system, only you are the real owner of your money and only You have access to it.
Using tools such as a local Tkeycoin Core wallet or TkeySpace provides you with reliable storage, privacy, and security.
TkeySpace, in turn, adds maximum usability by combining the highest level of security and easy intuitive design.

https://i.redd.it/f0de51vuntx41.gif

How does TKEYSPACE provide security?

TKEYSPACE is one of the first applications that support blockchain in a mobile device and is also the first decentralized application of the TKEY platform.
Its serverless architecture provides the highest level of security for storing all assets in the application. unlike centralized applications that are managed by companies, TkeySpace does not have a Central management authority and operates in accordance with all the principles of peer-to-peer networks.

https://preview.redd.it/4bret8hwntx41.png?width=1253&format=png&auto=webp&s=535c5d879a36eac4ca8c807ee7af1b5fe05e12a9
As we said above, the wallets in the blockchain have a public and private key. Centralized applications usually store users ‘private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
TkeySpace-stores the encrypted key only on the user’s device and in encrypted form. The encrypted key is displayed as a mnemonic phrase (backup phrase), which is very convenient for users. Unlike complex cryptographic ciphers, the phrase is easy to save or write. The backup phrase provides the maximum level of security and thanks to its usual appearance, an attacker is unlikely to ever guess what these words are and what they are for.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If the phrase consists of 12 words, then the number of possible combinations is 2048¹² or 211³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in the strict order as it was presented after generation.
And so that you do not get confused in the definitions and concepts, we will briefly describe simple and clear principles of how it all works. Let’s look briefly at the factors.

Lock Screen

The simplest thing that protects your phone from unauthorized access is Pincode, a snake, a fingerprint or a Face Id login. And it would seem that this is related to TKEYSPACE?
https://i.redd.it/sspjjsgyntx41.gif
  • At a minimum, it is almost impossible to open new mobile devices and pick up a pin code, even in the case of theft, most often the factory settings are reset, which leads to the deletion of all data on the phone, respectively-your funds are safe even for this reason.
  • Even if there was some “craftsman” and somehow managed to change the pin code on your device, the TKEYSPACE app will automatically delete all the keys and backup phrases, the wallet will simply be empty, and the attacker will be left with nothing.
As we can see, even a simple screen lock with a pin or fingerprint protects your data. It’s not as simple a screen lock as you and I might think.
Every platform, whether it’s Android or AppStore, uses specialized key stores. Cryptography, symmetric and asymmetric encryption, keys, and certificates are directly related to this task.
Keys and certificates that are used to protect information must also be securely protected. Android uses Keystore, a certificate and a Keystore, for this purpose.
Keystore is a specialized secret data store that is used by Java applications to encrypt, authenticate, and establish HTTPS connections.
For two-way authentication, the client and server exchange certificates, respectively, and the server and client must have a Keystore with a private/public key pair and a certificate. In other words, the Keystore is used to store keys and certificates that are used to identify the key owner (client or server).
Starting with Android 8, the encryption systems have been upgraded, the system is checked for signs of hacking at startup, and the screen lock allows you to restrict access to the device. Data encryption and the use of keys ensure the security of information when it is stored and transmitted.

https://i.redd.it/2c0b9re1otx41.gif
In the new version of the OS — Android 9 (Pie) — the developers also added support for hardware to protect against unauthorized changes.
Android apps run in an isolated software environment that restricts access to your information to other apps. OS components are also protected, which prevents attackers from exploiting system errors for their purposes.
Android uses both hardware and software to protect users and their data. Therefore, even at the operating system level, there are a lot of security factors. Of course, if you “flash” the phone (change the factory firmware) and enable Root access, this will reduce the security of Your device, but this is more an exception than a rule and such changes are usually introduced by very experienced users.
IOS uses Keychain — a specialized database for storing metadata and confidential information. Using a Keychain is the best practice for storing small pieces of data that are critical to your apps, such as secrets and passwords. In addition to the Keychain, Apple provides a full range of maximum protection for Your device.
And so we will continue,

Passcode in the app

Now we understand that to get access to the tools, an attacker needs to hack the hardware security of the Google and Apple giants to somehow get access to the app, which is impossible.
To increase security and eliminate other risk factors, we have included an access code (secret code) in the app.
You set an additional level of security by enabling a pin code to log in to the app. The access code additionally encrypts all data stored in the app.
Just so you understand — it’s not just numbers that you enter on the screen, this combination affects the ciphers inside the app. When creating a key, a user interface element is called. when the user swipes the screen, the application receives a random set of bytes — thus, all information is additionally covered by a new layer of cryptography.
And as we said above, if you try to disable the pin code, the app will delete all the data, and the attacker will be left with nothing.
As we have already realized, only 2 of these factors provide the maximum level of security for the TKEYSPACE application.
And the most important thing is that the application runs on the blockchain, which guarantees its full Autonomous operation, data immutability, and privacy.
Generation of new addresses, absence of accounts, phone numbers, e-mail and other personal data-provides you with a social level of security, which is a huge advantage in our time.
In a world where security is based on the level of cryptography, attackers try to influence You with the human factor using social engineering, so when you use applications with accounts, phone numbers, you have more risks.
Social engineering is a method of obtaining the necessary access to information based on the characteristics of human psychology.
For example, a copy of a SIM-card has become a new tool for fraudsters, but there is no personal information in TKEYSPACE, so even such groups of fraudsters can’t get access to your funds.

You don’t have to worry about security — it’s already built into the TKEYSPACE system.

A mixed encryption system based on the principles of computational complexity, with the deterministic generation of signatures using elliptic curves, provides absolute security and safety of user funds, and reserve phrases will help you restore funds at any moment.
A mnemonic phrase is 12 or 24 words that are generated using the entropy of random numbers.
If the phrase consists of 12 words, then the number of possible combinations is 2048¹² or 211³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in the strict order as it was presented after generation.
Only you and no one else has access to the phrase. When you get the key, the app has restrictions on the screenshot, and the clipboard is disabled, which protects against malicious software.
It is you, as a user, who sees the phrases, and everything in the device is encrypted, the blockchain architecture protects against hacker attacks, information forgery, and other hacks.
For those who are a bit obsessed with persecution mania, we offer a small lifehack:
Buy several USB drives, connect them to a device that does not have access to the Internet, preferably on a clean operating system, create a text file, write backup phrases there, and encrypt the USB drives with passwords.

https://i.redd.it/shan90o4otx41.gif
Once again, to ensure security and easy recovery, it is enough to record backup phrases once and make several backups. you do not need to resort to an additional encryption method, because we have already done everything for you :)

TomoChain AMA with DAppBird: Public blockchain applications for businesses.

TomoChain AMA with DAppBird: Public blockchain applications for businesses.

https://preview.redd.it/a07hgl4am5t41.png?width=690&format=png&auto=webp&s=df718220bddfbeb6e3790328177769859df08874
Hi everyone. Pleased to be here! Thank you for taking your time to join me.
I’m the Chief Business Development Officer for TomoChain.
Educationally I graduated university with degrees in both Industrial Engineering and Economics from Georgia Tech, and later earned an MBA from the Wharton School of Business.
I grew up as a gaming addict and have a video game collection that is a bit unwieldy. Dozens of consoles and, at one point, over 13 classic arcade machines.
So, before crypto, I spent much of my profession in the gaming space. I was a Game Designer, Game Producer, and eventually Studio Head for a major games studio that was recently purchased by Rockstar Games. I have run my own game-related tech businesses as well.
I fell into crypto back in 2014, and over time it became a second passion of mine as I began to truly understand the value of decentralization. True ownership of data was not possible until Bitcoin came along and that is simply a powerful and game-changing message to a world structure built on an opposing foundation.
Brief Introduction

https://preview.redd.it/8p7jm15ul5t41.png?width=739&format=png&auto=webp&s=8b572bdee2c56ffa29a1d628dda7332fac0fac50
TomoChain is a Public Blockchain powered by Proof-of-Stake Voting. TomoChain launched into Mainnet 1 year ago in December 2018. It is secured by 150 Masternodes, of which I’m proud to be an operator myself. TomoChain is EVM Compatible and runs at a speedy 2000 TPS with a 2 Sec Blocktime. Gas fees are almost zero too.
Based out of Vietnam, TomoChain is Southeast Asia’s largest public blockchain. We are focusing on developing a full suite of DeFi products. We also have commercial and enterprise clients. TomoChain has a number of major crypto-partnerships including notables like Neo Blockchain, Chainlink and Crypto.com. Our Masternode network is run by some of the most recognizable players in the space as well, including Neo Global Capital, CoinGecko, HashQuark, KuCoin, and more large players are on the way.
TomoChain earned its place onto Binance.com with a fee-free listing last year by winning the BinanceDEX community vote in August 2019. Binance has written us up in a detailed Binance Research Report and awarded us the V-Label. We have also been in a number of their reports, including those related to Dapps and DeFi. We have been interviewed by Forbes.com official and had an in-person interview at NASDAQ, in the heart of Times Square, about TomoChain and our upcoming TomoX Protocol.
In China, specifically, we have been integrated into and have solid relationships with various blockchain players including HashQuark, HashKey, CoboWallet, Conflux, and many others. We launched an Ecosystem Development partnership with Neo Blockchain last December and co-hosted a meetup + workshop with them as well.

https://preview.redd.it/anszszoxl5t41.png?width=733&format=png&auto=webp&s=1b8930c8c3df9357109d49f67f1a35edd6f803d0
GEARED FOR REAL WORLD USE
Now, let’s talk about how TomoChain has been built for real-world use.
We’re looking at Payments & DeFi as low hanging fruit when it comes to user adoption and TomoChain is developing a suite of tools to support this. The biggest challenge for having users benefit from Blockchain on a day-to-day basis is how much friction is involved to acquire, store and use it. Even stable coins are dual currency systems. The Stablecoin and then the Native Token to pay gas fees. Blockchain is simply not user-friendly.
Our view is that the true solution for Blockchain adoption by the world is end-users shouldn’t need to know they are using blockchain technology at all. It should be a hidden technology layer, similar to payment processor settlements or even the internet distribution centers/routers that power this very AMA we’re all participating in right now. Do we need to know the underlying technology infrastructure to use them? Nope.
We are developing a system to hide this friction, so the TomoChain blockchain can be integrated into real-world applications that you use every day on mobile or web.
There are 3 protocols that we are building to enable this future: (1) TomoZ: Zero Friction (2) TomoX: The DEX Protocol (3) TomoP: The Privacy Suite.

https://preview.redd.it/irwduto4m5t41.png?width=741&format=png&auto=webp&s=56e21c8e56b86af197344d7a043d073456c53181
TomoZ: Zero Friction - Our TomoZ protocol is a core starting point to the solution for mass market use of blockchain technology. TomoZ: Zero Friction allows for token issuance and use by having gas fees paid by the token itself. That means you don’t need TOMO to send transactions. You don’t even need to know you’re using the TomoChain blockchain.
So you could buy a cup of coffee at a café using loyalty points that are TomoZ tokens. The customers redeem for their coffee or earn it, but they don’t even have to know it’s a blockchain token which they actually own.
This approach is structured to enable the next million-plus users to utilize blockchain as a technology layer. After all, the real value of any Blockchain is in its utilization of high-quality transactions.
Now, TomoZ transactions aren’t FREE. It actually does use TOMO, but that’s hidden from the end-user. The way it works is that the token issuer deposits a small amount of TOMO into a pool. Every time the token is sent, TOMO is taken from this pool to pay the Masternodes.
The key is that the end-user doesn’t need to get involved with internal workings, which is why we call it the Zero Friction protocol
Now let’s talk about TomoX: The DEX Protocol
TomoX is an upcoming DEX Protocol that allows anyone to launch their on permissionless Decentralized Exchange in minutes. It requires very little technical knowledge making it a near turn-key solution.
TomoX is the fastest DEX experience since it’s a Layer 1 protocol. This means it’s run and secured by the entire TomoChain network. Our Masternodes manage the DEX instructions directly, rather than other DEXs that operate as a Layer 2 protocol. What this means is TomoX DEXs will operate at about 50x faster than a typical 0x exchange. That significantly improves the end-user experience.
TomoX DEX operators have access to a shared liquidity pool across all DEXs. That means a user buying on one DEX can be matched with a user selling on another DEX. Of course, Operators can customize and choose which tokens to include.
TomoX is fully decentralized since the Order Book is on-chain. Many other semi-decentralized exchanges store the OB on a centralized service in order to speed up the execution. That means there is a centralized point of weakness for them. TomoX minimizes custody and security challenges that centralized exchanges have too since all users are always in possession of their assets.
TomoX is currently in testnet and you can checkout TomoChain’s own DEX, aptly called TomoDEX, here: https://dex.testnet.tomochain.com/
Here is a link to get some free Testnet TOMO that can be used on the testnet version of TomoDEX: https://faucet.testnet.tomochain.com/
And finally, there is TomoP: Privacy Suite - TomoP is currently in testnet and is going to be the FASTEST way to send tokens privately. 2-4 seconds fast!
Any token issued on TomoChain will be able to utilize TomoP to send privately and anonymously. And that’s not all. We are including access to wrapped BTC, ETH, USDT, and other tokens that can also utilize the blazing speed and privacy that TomoP will offer.
Dapp privacy is a major part of TomoP. It is going to allow for the creation of Dapps to be built to handle customer data with true privacy, including from the Dapp operators themselves. This can jumpstart a new wave of applications geared towards hiding user information, transactions, assets owned, etc.
We are issuing a new token standard (TRC21p) which will be purely private. The only data available will be on its token supply. Token issuers can optionally provide auditing access to enforcement authorities to meet regulatory compliance. What this means is if the next Global PayPal/Skrill/Alipay competitor can build their service right on TomoChain and meet the most basic criteria required to stay above board in many jurisdictions.

Questions from the host
1. It’s been stated that TomoChain was on track to be a cash flow positive business, is it currently cash flow positive? What services or products is it offering to bring in this revenue?
Yes, absolutely. Our plan is to be cash flow positive this year. This really goes back to the level of experience our executive team has. Everyone is seasoned, having come from different fields, in big business and startups. Before the crazy boom of ICOs and IEOs, raising funding for traditional startups required considerable proof that there was market fit, that there were actual customers to drive revenue, and a model for growth.
We knew that TomoChain’s funds raised during the ICO were for a space that has yet to prove itself so the company had to be smart in budgeting for an uncertain future. And part of that initial preparation was selling much of the ICO proceeds into fiat. Something MANY blockchain startups did not do, largely due to ambitious teams that are also headed by very inexperienced leaders. So while the bubble burst, we had capital to continue operations and to even scale it.
And, we ARE running a business. A sustainable business requires us to identifying areas to generate income in order to minimize risk and to sustain the business in the long term. So we do both consulting and services work by helping clients to develop wallets, launch tokens (Orbyt), build exchanges (AIS), and of course enterprise solutions on the blockchain of which we have clients based out of Japan and in the Middle East using blockchain for traceability solutions across various industries from automotive, healthcare, and food.
2. What is the most strategical step TOMO is doing to bring adoption of TOMO coin to our daily lives?
Empowering businesses with a truly scalable blockchain that can be used by thousands and millions of users. We see user adoption of blockchain coming from businesses that base their solutions on blockchain technology. And, TomoChain has a number of real income-generating companies that have built on us, from exchanges to payment services to enterprise clients. Not bad for 1 year I say, especially during a stagnant market. Here are some examples.
UcarPac – A Top 10 User Car company in Japan is building traceability solutions on the blockchain. We completed a POC at the end of last year. After the assessment, the client decided it was solid and commissioned Phase 2 to expand the development of the project for commercialization purposes
Triip Protocol – Triip is a destination service for travelers to book vacations powered by Blockchain. Triip is a Shark Tank Vietnam alumnus, and the first ICO on TomoChain. Users can book tours and staycations using Triip or TOMO tokens.
WisePass – A service that sells subscription services to get discounted Starbucks, Singha Beer, and even makeup (of all things) integrated TomoChain as a payment solution
“Undisclosed Vendor” – Soon to be announced, a large player in the corporate gift giving business is also launching a Dapp on TomoChain to allow for them to make purchases with TOMO across thousands of items.
Maka - A peer-to-peer marketplace to conveniently buy/sell TOMO and other blockchain tokens using standard payment gateways, including e-wallets and bank transfers.
Coin98 – A local Vietnam crypto media company launched an App to allow for their community to earn their TomoChain token called C98 and use it for products and services geared around investors and gamers. The reception has been HUGE. 95,000 users and generating 500K+ transactions on our blockchain within 3 months of their launch! They are proving that innovative new business models can be adopted relying on and being blockchain specific.

https://preview.redd.it/mlol3zl6m5t41.png?width=759&format=png&auto=webp&s=4a516404ed6a15de0e56fd08ed1e354a53c4191e
3. Do you have any plans to collaborate with developers or attract more Dapps built on TomoChain?
We are today. Our founders run the largest Blockchain Developer community in Vietnam and we work with a number of them to help develop solutions on the blockchain.
Our team has held Hackathons a few times over the last couple years and we have done developer workshops too, including one with Neo Blockchain. And this year we are working closely with educational institutions to launch blockchain courses in Vietnam.
Every Dapp developer we work with is a partner. We try to provide as much support as possible, both technical and marketing. A number of Dapps are games on TomoChain and we hold contests regularly to promote the developers and their titles.
Since we are focusing on alleviating the friction of blockchain technology, we are building out an API that will make it even easier for developers to integrate blockchain into standard applications. This is intended to allow standard non-blockchain application developers to operate in an environment they are accustomed to while also having the benefit of blockchain technology accessible.
Onboarding more developers will take time. However, I’m confident we’re on the cusp of something wonderful in the coming years that will change the relationship between users and applications enabled by blockchain. Entirely new economic structures can be set up since it’ll be the users owning all of their data for the first time in digital history. And true ownership is a powerful motivator that can be harnessed by innovative blockchain businesses.

It is hoped that Earthcoin will bring new opportunities to the global village economy under the influence of the new crown virus, and the Earthcoin EAC blockchain will build a new global village.

It is hoped that Earthcoin Earthcoin will bring new opportunities to the global village economy under the influence of the new crown virus, and the Earthcoin EAC blockchain will build a new global village.
Everyone becomes a member of the global village via the Internet, but the real world is divided into many countries and regions. National and regional laws, currencies are inconsistent. The advent of blockchain can build a global village.
1: Global Village, EarthCoin
A word that the Global Village heard a long time ago seems to be a bit old now. The rapid development of modern science and technology has reduced the space-time distance on the earth, and international communication has become increasingly frequent and convenient, so the entire earth is like a small village in a vast universe. The global village in the Internet era is imperfect, because only the rapid transmission of information, and other aspects are deeply affected by the real world.
Earth's development of the digital economy is inseparable from Earth Coin EAC! EAC can help users to pay instantly to anyone on the planet. Earthcoin is a global decentralized payment network and digital currency that calculates the value of labor and quantifies the resources of the earth. Inspired by Bitcoin. Earthcoin can perform fast transactions with little or no fees. No login, registration or hidden fees are required. Users receive Earthcoin or send Earthcoin from any Earthcoin address in the world within seconds. Earthcoin uses P2P technology, and there is no central management agency; the network collectively manages transactions and issues Earthcoin. Earthcoin is also open source. Its design is public participation. No one can own or control Earthcoin. It is committed to sustainable and fair development. It calculates labor value and quantifies earth resources. Every earth person can participate.
2: The current global village
In reality, everyone's connection is broken. You have to use your own currency, you have to abide by your country's laws and regulations, and you have to follow a local law to use the local currency when you go to an area. Many things are inefficient because of this split. For example, bank cards: everyone has a lot of bank cards. There is nothing necessary. How many cards are wasteful. If you want to transfer money, the bank is different. If you want to transfer money from two different countries, you have to go through A complex network is very inefficient. Earthcoin is a global decentralized payment network and digital currency that calculates the value of labor and quantifies the resources of the earth. Can completely solve these problems.
3: If the blockchain changes the global village
The above problem is the reason why there is no strong center. If there is only one country and a bank is so big, things can be very efficient. But it is impossible. The United Nations and the World Bank can be political centers and financial centers by name, but the actual situation is not. The actual power is poor. And it may not be a good thing to create such a strong center, Earth Empire? The emergence of the blockchain has created a new possibility without a center! A lot of things need to be done by the strong center, but they are done just as well by going to the center. 1. In the past you needed the government to prove who you are, your mother is your mother, now the blockchain can. 2. In the past, you needed to use different currencies in different countries, and now Bitcoin Geocoin is accepted in any country, regardless of exchange rates.
The short confirmation time of the Earthcoin EAC block gives it infinite potential to extend to payment applications.
Everyone knows that Bitcoin BTC is the most robust and secure currency in the block. Even a few years ago, many investors around the world have used it as a tool for their own wealth transfer and storage. In the field of value storage, its credit is unmatched, which is the fundamental reason for its market value of 1.4 trillion. However, in the global micropayment application, Bitcoin BTC requires 10 minutes for each block confirmation, and 6 blocks can ensure accurate transactions. If you are shopping in the supermarket or participating in remittances, fundraising, etc., you only pay a sum of money. Wait for 10-60 minutes, it will definitely make people restless, don't even think about doing anything.
Earth Coin EAC has a block time of 60 seconds, and 5 blocks can confirm the transaction. Although there is no Alipay and WeChat Express supported by a centralized database, you have realized a point-to-point seamless link payment globally. , Waiting for confirmation within a few minutes is completely acceptable!
At present, the United States and Europe have begun to encircle China's Alipay and WeChat in terms of financial payment, because it is quickly eating away the cake of the cross-border payment of US dollars and euros in the circulation between Southeast Asia and Europe. Zuckerberg, knowing that his Lbria is equivalent to QQ currency ten years ago, but the US government has almost allowed it [to resist the pressure brought by Chinese payments, but if it is to be issued, it will become the Federal Reserve. And the US dollar's grave diggers were ultimately rejected by Congress], they are all centralized in nature, just like Huawei, no matter how good the product quality is, and where the service is in place, but as long as Huawei is found as a centralized organization, it is because of geopolitics between countries. And under economic coercion, bans are banned. But with a payment system developed using pure POW digital currency with a short confirmation time, no government can start, and people in Asia, Europe, Africa and the United States will long to use them to complete transnational payments in the context of globalization.
Four: Summary
This article triggered my thinking on the blockchain. What is the purpose of decentralization and why do many things go to the center! !! !! In a small area, a strong center is enough to accomplish many things efficiently, but when there is no strong center and it is difficult to exist globally, many simple things are very complicated. 1. Online transfer, if there is Alipay, then it will be a few seconds, but if a Chinese person uses Alipay to transfer to an overseas PayPal account, it is a massive project. After a bunch of banks, exchange rates fluctuated and various fees were charged. Blockchain can transfer money in a few minutes like Alipay. The short confirmation time of the Earthcoin EAC block makes it have endless potential to extend to payment applications. 2. Self-certification, you have to prove who you are, you need proof of where you are registered, you ca n’t prove who you are, you ca n’t prove it, but the district Blockchaining your private key can prove who you are. 3. More secure, Alipay transfer is a strong center, which is theoretically very safe, but it is a black box for you. If something goes wrong, if something goes wrong, how do you prove that you transferred, everything depends on the credit of Alipay, but the blockchain depends on It is code, and everyone can view the public code, which is more credible. Blockchain has many limitations. Without a strong center, there is no strong center, but in many cases, there is no strong center, and then a blockchain is necessary. I hope Earthcoin brings new opportunities to the global village economy under the influence of the new crown virus! (Source network)

Online Bitcoin Trading: Discover The Keys To Making A Powerful Earnings Trading Bitcoin

Action 1 - Comprehending Bitcoin And The Block-Chain

Bitcoin is a peer-to-peer payment system, otherwise called electronic cash or virtual currency. It provides a twenty-first century option to traditional banking. Exchanges are made through "e wallet software application". The bitcoin has in fact overturned the conventional banking system, while running beyond federal government guidelines.
Bitcoin utilizes modern cryptography, can be provided in any fractional denomination, and has a decentralized circulation system, remains in high need worldwide and provides numerous unique benefits over other currencies such as the United States dollar. For one, it can never ever be garnished or frozen by the bank( s) or a federal government company.
Back in 2009, when the bitcoin deserved simply 10 cents per coin, you would have turned a thousand dollars into millions, if you waited simply 8 years. The variety of bitcoins offered to be bought is restricted to 21,000,000. At the time that this short article was composed, the overall bitcoins in flow was 16,275,288, which indicates that the portion of overall bitcoins "mined" was 77.5%. at that time. The present worth of one bitcoin, at the time that this short article was composed, was $1,214.70 USD.
According to Costs Gates, "Bit coin is amazing and much better than currency". Bitcoin is a de-centralized type of currency. There is no longer any requirement to have actually a "relied on, third-party" included with any deals. By taking the banks out of the formula, you are likewise removing the lion's share of each deal cost. In addition, the quantity of time needed to move cash from point A to point B, is lowered formidably.
The biggest deal to ever occur utilizing bitcoin is one hundred and fifty million dollars. This deal happened in seconds with very little charge's. In order to move large amounts of cash utilizing a "relied on third-party", it would take days and expense hundreds if not countless dollars. This discusses why the banks are strongly opposed to individuals purchasing, offering, trading, moving and investing bitcoins.
Just.003% of the worlds (250,000) population is approximated to hold a minimum of one bitcoin. And just 24% of the population understand what it is. Bitcoin deals are gotten in chronologically in a 'blockchain' simply the method bank deals are. Blocks, on the other hand, resemble specific bank declarations. Simply put, blockchain is a public journal of all Bitcoin deals that have actually ever been performed. It is continuously growing as 'finished' blocks are contributed to it with a brand-new set of recordings.

Discovering a respectable bitcoin trading business that provides a high return is vital to your online success. Making 1% each day is thought about a high return in this market. Making 10% each day is difficult. With online bitcoin trading, it is practical to double your digital currency within ninety days. You should prevent being tempted by any business that is providing returns such as 10% daily. This kind of a return is not practical with digital currency trading. There is a business called Coinexpro that was using 10% daily to bitcoin traders. And it wound up being a ponzi plan. If it's 10% each day, leave. The abovementioned trading platform seemed really advanced and discovered as being genuine. My recommendations is to concentrate on trading your bitcoin with a business that uses affordable returns such as 1% daily. There will be other business that will try to separate you from your bitcoin utilizing unethical techniques. Be extremely mindful when it pertains to any business that is using impractical returns. When you move your bitcoin to a recipient, there is actually absolutely nothing your can do to get it back.

Your ROI ought to likewise be upwards of 1%+ daily due to the fact that the trading business that you are providing your bitcoin to, is more than likely earning upwards of 5%+ each day, usually. Your ROI needs to likewise be immediately moved into your "e-wallet" at routine periods, throughout your agreement term. There is just one platform that I feel comfy utilizing. It pay's each bitcoin investotrader 1.1% daily in interest in addition to 1.1% each day in capital. This kind of a return is staggering compared to what you would make with standard monetary markets, nevertheless, with crypto currency, it prevails. A lot of banks will payment 2% annually!
If you are needed to carry out tiresome activities such as logging into your account, sending out e mails, clicking links etc, you certainly require to keep looking for an appropriate trading business that uses a set-it-and-forget-it kind of platform, as they definitely exist.

IPVanish Review - Why its a great VPN

IPVanish is a popular VPN service particularly with Android and Fire TV Stick users, and it makes a very strong claim on its homepage – that it’s the “World’s Best VPN.”
Seen this sort of statement before, right? It’s certainly one of the leading VPN providers out there, but is it really the best VPN overall?
We never take a provider’s word for it, so we decided to put IPVanish to the test – a very extensive one – to see if its claims are to be believed.
We were particularly keen to find out:
How good is IPVanish? Is it safe to use? Is IPVanish very fast? Does it work with Netflix? Is torrenting and P2P allowed? Is it the best VPN app for Firestick? But before we answer each of these (and many more) questions, lets see the pros and cons of IPVanish VPN:
Pros Cons Very impressive speeds Works with Netflix Great for torrenting & Kodi No-logs policy & no IP/DNS/WebRTC leaks User-friendly apps for PC, Mac, iOS, & Android Good server network across 50 countries Won't work with BBC iPlayer, or in China Short refund period Based in privacy-unfriendly US Desktop app could be more user-friendly Works with
Netflix, HBO, Torrenting, Kodi
Available on
Windows Mac Ios Android Linux Price from
$4.87/mo
As you can see IPVanish certainly does have many strengths to shout about.
It’s now time to take a very close look at the attributes and features of each IPVanish app, starting with how fast it is.
Speed & Reliability IPVanish is a consistently fast VPN
IPVanish is a very fast VPN service, with some of the quickest speeds we’ve seen in our tests.
IPVanish didn’t slow down our connection too much, and it is more than fast enough for HD or 4K streaming.
Speed results from our physical location in London (100Mbps fibre optic connection) to a London test server.
Before using IPVanish:
DOWNLOAD Mbps 93.76
UPLOAD Mbps 97.58
PING ms 2
When connected to IPVanish:
DOWNLOAD Mbps 84.13
UPLOAD Mbps 90.33
PING ms 7
Download speed without IPVanish: 93.76Mbps
Download speed with IPVanish: 84.13Mbps
Our download speed loss when IPVanish is running: 10%
Downloads, uploads and latency when using IPVanish are among the best we’ve seen, making this VPN a very smart choice for gamers and torrenters alike.
It’s also one of the most reliable VPN services we’ve seen, providing consistently fast speeds from one test to the next.
Here are the average speeds you can expect when using IPVanish to connect out to various locations around the world (from the UK):
USA: 53Mbps (download) & 37Mbps (upload) Germany: 76Mbps (download) & 81Mbps (upload) Singapore: 25Mbps (download) & 2Mbps (upload) Australia: 24Mbps (download) & 6Mbps (upload) Server Locations Over 40,000 IP addresses across 77 locations
Globe with a blue flag 50 Countries Image of a city landscape 77 Cities Image of a pink marker 40,000+ IP Addresses See all Server Locations IPVanish VPN gives access to more than 1,300 servers worldwide and over 40,000 IP addresses, which is one of the highest numbers of IP addresses we’ve ever seen. This means that you’re unlikely to experience VPN server congestion and slow speeds while connected to IPVanish.
The 50 countries in IPVanish’s VPN server network are well spread-out, including some less common nations like Moldova and the Philippines (in addition to all the typical countries like US, UK, Canada, Australia, and more).
List of IPVanish server locations
IPVanish provides its customers with city-level options in the US (19 cities), UK (4), Canada (3) Australia (2) and Brazil (2).
US-based users can choose from IPVanish servers in:
Central – Chicago, Dallas, Denver, Houston, Jackson, Milwaukee, St. Louis East – Ashburn, Atlanta, Boston, Cleveland, Miami, New York West – Las Vegas, Los Angeles, Phoenix, Salt Lake City, San Jose, Seattle We’d love to see more city-level selections in Australia – mainly Perth which is located on the West coast – and more server options in South America, where only Brazil and Colombia are served.
The high number of VPN servers in IPVanish’s network is enough to offset these minor complaints, though.
IPVanish is one of the few VPN providers to own its entire (or very close to) server infrastructure, meaning they rent very few servers from third-parties.
Streaming & Torrenting Excellent choice for torrenting & Netflix
Despite IPVanish being one of the fastest VPNs we’ve seen, it’s just not a great VPN for streaming.
Most of IPVanish’s US servers work for Netflix, although it can occasionally take a while to load, but all of its UK servers are currently blocked by BBC iPlayer and according to IPVanish they are not looking to work on fixing this.
If streaming BBC iPlayer is important to you, read through our dedicated guide or take a look at our NordVPN or CyberGhost reviews, two VPN services that work well with BBC iPlayer.
IPVanish has also confirmed it isn’t working with Amazon Prime Video or Hulu at the moment.
Torrenting IPVanish is, however, one of the best VPN services for torrenting we’ve tested, with very fast speeds and a watertight logging policy.
Torrenting is permitted on all of its servers and when we checked for IP/DNS leaks, we found none.
Not to mention that it has a VPN kill switch, but more on this below.
Therefore, we recommend IPVanish VPN for all P2P activity including Kodi for which IPVanish is currently the #1 VPN service.
Bypassing Censorship No good for China
IPVanish is very upfront in saying that the VPN service won’t work in China, despite being equipped with an array of obfuscation tools.
We really appreciate IPVanish’s honesty on this topic. IPVanish also provides a useful list of other countries the VPN won’t work in: you can find this on the support section of the IPVanish website.
List of IPVanish banned countries
IPVanish states that it is “forbidden to do business in”:
Myanmar Cuba Iran North Korea Sudan Syria IPVanish states that its domain, ipvanish.com, is blocked in:
Qatar Saudi Arabia United Arab Emirates (UAE) China Kazakhstan It’s not just IPVanish’s domain that is blocked in these countries, and many users have reported that IPVanish’s apps don’t work either.
If you live or are travelling to a high censorship country then we suggest you consider using VPN services like ExpressVPN or VyprVPN to bypass aggressive internet censors.
Platforms & Devices Works with all major platforms & devices
Apps Windows Logo Windows Mac Logo Mac iOS Logo iOS Android Logo Android Linux Logo Linux Router Logo Router IPVanish has custom VPN apps for all popular mobile and desktop operating systems so you can use them on:
PCs Apple Macs iPhones Android devices You can also setup IPVanish on other devices using manual workarounds (see the ‘Games Consoles & Streaming Devices’ section below).
Games Consoles & Streaming Devices AppleTV Logo AppleTV Amazon Fire TV Logo Amazon Fire TV Chromecast Logo Chromecast Nintendo Logo Nintendo PlayStation Logo PlayStation Roku Logo Roku Xbox Logo Xbox IPVanish is a good VPN to use with gaming consoles and streaming devices.
IPVanish is our number 1 VPN pick for the increasingly popular Amazon Firestick, and it’s super easy to install and use.
You can also use IPVanish on 10 devices at once, which is very generous (the average among the top VPN services is about 5 simultaneous connections).
You can also install IPVanish on your home router so that all your internet traffic at home is protected.
Browser Extensions Unfortunately, IPVanish doesn’t have any VPN browser extensions, which is a shame and one of the very few areas where it seriously lags behind its competitors.
If you want to use a VPN extension with your web browser then take a look at our:
Best VPN extensions for Chrome Best VPN addons for Firefox Encryption & Security One of the safest providers we’ve reviewed
Protocol IKEv2/IPSec
L2TP/IPSec
OpenVPN (TCP/UDP)
PPTP
Encryption AES-256
Security DNS Leak Blocking
First-party DNS
IPV6 Leak Blocking
Supports TCP Port 443
VPN Kill Switch
Advanced features SOCKS
Please see our VPN Glossary if these terms confuse you and would like to learn more.
We believe that IPVanish is one of the most secure and private VPN services available.
IPVanish mainly uses the OpenVPN and IKEv2 protocols and encrypts your online traffic with the ‘unbreakable’ AES-256 cipher, meaning you’re protected at all times. You can also connect using L2TP/IPsec, if you’d prefer.
IPVanish has a VPN kill switch to protect your privacy in case of a connection drop, plus a host of other advanced features to secure your web browsing. This includes SOCKS5 web proxy, which masks your IP address during P2P and VoIP connections – although this doesn’t encrypt traffic.
We also found IPVanish to be extremely safe, and free of IP or DNS leaks in our most recent tests:
IPVanish leak test results from browserleaks.com IPVanish’s leak test results when connected to its Chicago server
Logging Policy No-logs policy makes up for US jurisdiction
IPVanish doesn’t collect any user data at all, making it a no-logs VPN service.
Considering most VPN logging policies track at least server load or login information for maintenance purposes, this is what makes IPVanish a standout VPN for privacy.
In 2016, when under previous management, IPVanish was however found to be collecting logs when it handed information over to US authorities to aid in the prosecution of a user.
Since being acquired a number of times since then, IPVanish has turned things around and we have no longer concerns about its approach to user privacy.
Jurisdiction IPVanish VPN was first released in 2012 by its former US-based owner HighWinds Network Group. IPVanish has since been acquired by StackPath and in 2019 by J2 Global which are both US-based companies.
As you can see IPVanish is, and has always been, operated by companies headquartered in the US, which does have very intrusive surveillance laws and is a member of the Five-Eyes data sharing agreement.
IPVanish being based in the US is largely irrelevant though as its no-logs policy means no identifiable information is collected by the VPN provider.
Ease of Use User-friendly install with lots of advanced features
How to Install & Set Up IPVanish Screenshot of the Windows download button on the IPVanish website Beginning the installation process is as simple as clicking the button to download the relevant software from the site.
Screenshot of the progress of our IPVanish Windows download You can check the progress of the installation here, but it usually only takes a couple of minutes from start to finish.
Screenshot of the completed IPVanish download Once the software is downloaded, you'll see this screen which prompts you to run the IPVanish app.
Screenshot of IPVanish's main dashboard on its Windows app IPVanish main dashboard shows key connection info and permits server selection. We like the nice graph too.
Screenshot of IPVanish's server list in the Windows app Power users will select servers from the main dashboard rather than the server list as it's a slicker experience.
Screenshot of the server location filters in the IPVanish desktop app IPVanish server list view with filters - it's mostly pretty good but not as optimal as using the main dashboard.
Screenshot of the advanced settings in IPVanish's desktop app IPVanish is rich with advanced settings for customizing connections and it's well laid out to boot. Nice!
IPVanish’s desktop VPN apps are perfectly simple to use, even if they could do with a bit of a visual overhaul as they are starting to look a little out-dated.
The advanced privacy settings are also easy to navigate, making IPVanish suited to both VPN beginners and more experienced users.
The mobile IPVanish apps lack a few key features, such as the VPN kill switch, but they do still provide a very good, user-friendly experience.
Customer Support Helpful support with 24/7 live chat
24/7 Email support Online Resources We found IPVanish customer support agents to be friendly and helpful no matter what we asked them about the VPN service.
Thanks to a recent update, IPVanish now also has 24-hour live chat support on its website.
IPVanish also has excellent email support, which provided us with impressively well-written responses, as well as an online FAQ for straightforward solutions to the most common issues.
If for any reason IPVanish isn’t working properly, you should be able to fix it quickly by following these guides.

Utopia, 1984 Group, bad PR, 1984 Group and [NetStalkers] media garbage

Utopia, 1984 Group, bad PR, 1984 Group and [NetStalkers] media garbage
What would you understand immediately reading my post, I do not want to throw mud at the program or the team of 1984. I just want to explain to everyone that you need to look for advantages in everything and bring the matter to a logical conclusion. And the most important thing is to be committed to your work. And if you choose any product, you must be faithful to it to the end. Be the captains who are to the end with the ship, not the rats running from it.

Hello
In today's post, I would like to tell an interesting story that there is really worthwhile software in the world, what marketing is wrong, and how it is bad to turn to wrong media personalities. Of course, most people know about it. But I think this should be publicly shown, maybe for many and will be useful in the future.

But every cloud has a silver lining. In any case, I think this will be a good stress test for the web. So I can say that even if a bad PR company gives a good result.

Let's start from the very beginning, namely from the software Utopia and the 1984 Group. Of course, little is known about them; more precisely, practically nothing is known. But there is a brief information about her. All of course taken only from the official beta of the portal and block hackology
Spoiler for compact post) About Utopia ecosystem
Utopia – Anti 1984 Ecosystem

After all this had never been done before! Finally, we present an ecosystem that will change the way World communicates and handles financial transactions. Utopia brief taken from their official website. Mentioning ‘financial transactions’ makes one wonder that Bitcoin was also disrupting the conventional financial system

All those who value their data privacy would find this useful including activists and journalists knowing that their data is going straight to the designated user and no 3rd party can intercept their data. Currently the limit set for the attachments is 100 MB but as per the team it may be increased in future.

uWallet (Utopia Wallet)
All financial functionality can be found in Utopia built-in uWallet. uWallet allows you to make and accept payments denominated in Utopia cryptocurrency ‘Crypton‘, accept payments at your website, pay by Crypto Cards without revealing your Identity or bill fellow Utopia users for your services. With uWallet you can store value in Cryptons, receive mining rewards, use uVouchers, request payments and accept payments using the built-in API.


Utopia Mining – Crypton
Utopia has an inbuilt cryptocurrency called Crypton (CRP), which is proof-of-stake therefore a modest machine can also be used to mine cryptons through the GUI based Utopia application or with terminal based Mining bot which comes with the application.

https://preview.redd.it/aadlqb8crmc31.jpg?width=814&format=pjpg&auto=webp&s=2a100b98b2d912898d1b4a316f05f999846ab7b1


Utopia rewards users that support the ecosystem through Mining by emission of new Cryptons. When you run your Utopia software or bot you will receive your share of collective reward. Mining does not slow your computer down and is environmentally friendly. You may also run a number of bots at several servers or computers to multiply the Crypton mining speed.

uNS (Utopia Naming System)
Utopia has introduced uNS (Utopia Naming System) which is a unique naming system and independent from the conventional Domain Naming System. DNS is subject to pressure and censorship from less than prefect international laws. Domains can be revoked or suspended due to multiple reasons, such as non-response to WhoIS inquiry or other register policies, non-payment, government actions and so on.
uNS, in contrast, is a truly decentralized non-censored registry hosted by Utopia Network participants with no expiration dates, renewal fees, suspensions and revocations. There is only one rule: First come, First served.

https://preview.redd.it/pfwstp5grmc31.jpg?width=1024&format=pjpg&auto=webp&s=1e282b2ad57f61ae3e4a114e75a96e20f7fc3a73


uNS registered name should be unique. You may register as many uNS registered names as you want while registration is not free and costs are paid in crypton:
Single letter uNS costs 1000 CRP
Two letter uNS costs 500 CRP
Three letter uNS costs 5 CRP
Four letter or more costs 0.1 CRP

Miscellaneous Features
Making Groups, Adding users, Chatting and Emailing, Sending Mails and Mining Cryptons might be the highlights but Utopia claims to be an ecosystem therefore they had to incorporate many more features so that users of Utopia ecosystem do not feel the need to go out of the system. List of other useful features within the Utopia Application are listed
Packet Forwarding : uNS Manager lists option of ‘Packet Forwarding’ which is an internal system allowing any utopian user to host a website which can be accessed by the Idyll browser, the naming system of the website is explained above, if you register hackology uNS you can make a website and it will open when you visit http://hackology/ and that is it. This option allows to tunnel any kind of data between users in ecosystem, making possible to host different types of resources including websites inside Utopia Network. At the time of writing few fellow Utopia users made Utopia sites which can be accessed at http://trade/ and at http://crystalforest

File Manager : All files which are sent or received in Utopia can be accessed from the builtin file manager which also includes an image viewer. As of now the file transfers are limited to 100MB.
Voice Notes : Utopia also supports sending and receiving of Voice messages which you can send to those who are added with you.
Dark Theme : The program comes in standard theme but how can they miss out a Dark Theme for the privacy savvy ? Users can opt for dark theme by going to Tools > Settings > Interface and selecting the ‘Dark Space‘ theme
Utopia API : Utopia comes with a comprehensive API for users to incorporate in their own projects. For instance, using API you can accept payments denominated in Crypton at your website, automatically manage your channels, send instant messages and much more. To get started once you enable the API you can also access the API documentation.
Network Fee Structure : Utopia provides us with an option to view all the network enforced fee and they are updated live on the network as the fee structure changes, thus one can stay updated with the current fee structure. You can access the Network Fee from uWallet > Treasury Data > Network Fee

Game : Utopia also supports in-app games which can be played in multiplayer, as of writing there is a working Chess game.


You can find more about Utopia on Hackology Blog.

Well, now I want to say personally my opinion after using Utopia.

It is very difficult to judge a product at the beta test stage, but at the moment I can highlight both the pros and cons of both the program and the team that develops it. I want to notice that this is my subjective opinion and you can or may not share it. So, let's begin:

Advantages:
  1. In principle, everything is really anonymous, as far as can be judged really using this software.
  2. Non-indexable channels (If you make it private and hide it from the search) at least we tested it inside the ecosystem. To find even by keywords is not real
  3. Non-indexable pages that you create. If you do not have a direct link, find a site even in the global search is not possible
  4. Easy mining of krypton. Even the weakest computers do not load, very comfortable
  5. Convenient system of anonymity of user information (Without exchange of public keys, even the avatar will not work)
  6. An easy-to-learn interface that arrived to us from 2004 (Old School will understand and appreciate)
  7. In fact, it reminds the decentralized Internet and may well become such with the proper development
  8. Inside the ecosystem there are no labels and notions of who is who, which simplifies the interaction within it
  9. Intervention from outside is at least very difficult, tried methods known to us, failed
  10. Indeed similar to a decentralized ecosystem.
  11. The team quickly fix problems
  12. Availability of detailed and collapsible instructions to all APIs within the ecosystem

There are many advantages and if I list everything, the post will be unrealistically large, therefore I have identified the main ones, and everyone after use must decide for himself what he liked.

And now about the shortcomings, they will be more likely related to common problems than specifically to the software or the command:

  1. Many functions that will have to be mastered by yourself, almost 0 guides
  2. The reaction of the team to the problems through the support leaves much to be desired
  3. The presence of bugs (not critical and absolutely, just not pleasant, both visually and in use)
  4. Not the right choice of PR company to promote software
  5. The team is known for development but is not good friends with product promotion.
  6. Localization, while only English (Well, this is a lesser problem)
  7. Absence of the familiar function (for example, attached videos and the like)
  8. All traffic from the site, even if you put it on the UPU goes through you, and in fact it denies anonymity. Why is this a disadvantage? Not only which VPS will agree that you would put Utopia, because the software scans the ports, which is forbidden without identification on most of the UPU. This is problem. If you put on the UPU, of course, the ends will not come to you, but if Utopia is on your car and the site is on the UPU, all site traffic will go through your public IP, which does not promise any anonymity.

While this is the most powerful problems of utopia, there may be more petty, but it is really not significant.


And now let's talk about NetStalkers, and here they are, because in the title they are.

The fact is that the 1984 Group bought advertising from this media team. I’ll say right away that I have nothing against the truly existing NetStalkers movement, now it concerns only the YouTube media community. So, having bought advertising from this wretched, deceitful and hypocritical community, Utopi had problems, because lovers of free-mining mining, children and inadequacies from all over the CIS and their usefulness were even zero, rushed into the software, moreover, all this garbage put a system on the blades because of spam, a huge amount of spam for which the 1984 Group was not ready. This is actually a terrible move.

Our small team very much hopes that this team can still draw conclusions from this, since only we worked, we chose the most adequate and interested contingent for this software from the CIS and we hope that in the future we will continue to cooperate with them.

If you like this post, I will continue to conduct similar topics and develop these areas, perhaps I will write guides on Utopia and will support this direction.

At the moment, because of the bad PR campaigns from the media slag community, the CIS, they no longer approve traffic, however, it’s even embarrassing to say that it’s from the CIS because such a manifestation of our community leaves much to be desired and even shows us adequate people in extremely bad light .

IOTA BREAKDOWN: The Tangle Vs. Blockchain Explained
IOTA tutorial 1: What is IOTA and some terminology explained

Information

Firstly, what is IOTA?

IOTA is an open-source distributed ledger protocol launched in 2015 that goes 'beyond blockchain' through its core invention of the blockless ‘Tangle’. The IOTA Tangle is a quantum-resistant Directed Acyclic Graph (DAG), whose digital currency 'iota' has a fixed money supply with zero inflationary cost.
IOTA uniquely offers zero-fee transactions & no fixed limit on how many transactions can be confirmed per second. Scaling limitations have been removed, since throughput grows in conjunction with activity; the more activity, the more transactions can be processed & the faster the network. Further, unlike blockchain architecture, IOTA has no separation between users and validators (miners / stakers); rather, validation is an intrinsic property of using the ledger, thus avoiding centralization.
IOTA is focused on being useful for the emerging machine-to-machine (m2m) economy of the Internet-of-Things (IoT), data integrity, micro-/nano- payments, and other applications where a scalable decentralized system is warranted.
More information can be found here.

Seeds

A seed is a unique identifier that can be described as a combined username and password that grants you access to your IOTA.
Your seed is used to generate the addresses and private keys you will use to store and send IOTA, so this should be kept private and not shared with anyone. If anyone obtains your seed, they can generate the private keys associated with your addresses and access your IOTA.

Non reusable addresses

Contrary to traditional blockchain based systems such as Bitcoin, where your wallet addresses can be reused, IOTA's addresses should only be used once (for outgoing transfers). That means there is no limit to the number of transactions an address can receive, but as soon as you've used funds from that address to make a transaction, this address should not be used anymore.
Why?
When an address is used to make an outgoing transaction, a random 50% of the private key of that particular address is revealed in the transaction signature, which effectively reduces the security of the key. A typical IOTA private key of 81-trits has 2781 possible combinations ( 8.7 x 10115 ) but after a single use, this number drops to around 2754 ( 2 x 1077 ), which coincidentally is close to the number of combinations of a 256-bit Bitcoin private key. Hence, after a single use an IOTA private key has about the same level of security as that of Bitcoin and is basically impractical to brute-force using modern technology. However, after a second use, another random 50% of the private key is revealed and the number of combinations that an attacker has to guess decreases very sharply to approximately 1.554 (~3 billion) which makes brute-forcing trivial even with an average computer.
Note: your seed is never revealed at at time; only private keys specific to each address.
The current light wallet prevents address reuse automatically for you by doing 2 things:
  1. Whenever you make an outgoing transaction from an address that does not consume its entire balance (e.g. address holds 10 Mi but you send only 5 Mi), the wallet automatically creates a new address and sends the change (5 Mi) to the new address.
  2. The wallet prevents you from performing a second outgoing transaction using the same address (it will display a “Private key reuse detected!” error).
This piggy bank diagram can help visualize non reusable addresses. imgur link
[Insert new Safe analogy].

Address Index

When a new address is generated it is calculated from the combination of a seed + Address Index, where the Address Index can be any positive Integer (including "0"). The wallet usually starts from Address Index 0, but it will skip any Address Index where it sees that the corresponding address has already been attached to the tangle.

Private Keys

Private keys are derived from a seeds key index. From that private key you then generate an address. The key index starting at 0, can be incremented to get a new private key, and thus address.
It is important to keep in mind that all security-sensitive functions are implemented client side. What this means is that you can generate private keys and addresses securely in the browser, or on an offline computer. All libraries provide this functionality.
IOTA uses winternitz one-time signatures, as such you should ensure that you know which private key (and which address) has already been used in order to not reuse it. Subsequently reusing private keys can lead to the loss of funds (an attacker is able to forge the signature after continuous reuse).
Exchanges are advised to store seeds, not private keys.

FAQ

Buying IOTA

How do I to buy IOTA?

Currently not all exchanges support IOTA and those that do may not support the option to buy with fiat currencies.
Visit this website for a Guide: How to buy IOTA
or Click Here for a detailed guide made by 450LbsGorilla

Cheapest way to buy IOTA?

You can track the current cheapest way to buy IOTA at IOTA Prices.
It tells you where & how to get the most IOTA for your money right now. There's an overview of the exchanges available to you and a buying guide to help you along.
IOTAPrices.com monitors all major fiat exchanges for their BTC & ETH rates and combines them with current IOTA rates from IOTA exchanges for easy comparison. Rates are taken directly from each exchange's official websocket. For fiat exchanges or exchanges that don't offer websockets, rates are refreshed every 60 seconds.

What is MIOTA?

MIOTA is a unit of IOTA, 1 Mega IOTA or 1 Mi. It is equivalent to 1,000,000 IOTA and is the unit which is currently exchanged.
We can use the metric prefixes when describing IOTA e.g 2,500,000,000 i is equivalent to 2.5 Gi.
Note: some exchanges will display IOTA when they mean MIOTA.

Can I mine IOTA?

No you can not mine IOTA, all the supply of IOTA exist now and no more can be made.
If you want to send IOTA, your 'fee' is you have to verify 2 other transactions, thereby acting like a minenode.

Storing IOTA

Where should I store IOTA?

It is not recommended to store large amounts of IOTA on the exchange as you will not have access to the private keys of the addresses generated.

What is a seed?

A seed is a unique identifier that can be described as a combined username and password that grants you access to your wallet.
Your seed is used to generate the addresses linked to your account and so this should be kept private and not shared with anyone. If anyone obtains your seed, they can login and access your IOTA.

How do I generate a seed?

You must generate a random 81 character seed using only A-Z and the number 9.
It is recommended to use offline methods to generate a seed, and not recommended to use any non community verified techniques. To generate a seed you could:

On a Linux Terminal

use the following command:
 cat /dev/urandom |tr -dc A-Z9|head -c${1:-81} 

On a Mac Terminal

use the following command:
 cat /dev/urandom |LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1 

With KeePass on PC

A helpful guide for generating a secure seed on KeePass can be found here.

With a dice

Dice roll template

Is my seed secure?

  1. All seeds should be 81 characters in random order composed of A-Z and 9.
  2. Do not give your seed to anyone, and don’t keep it saved in a plain text document.
  3. Don’t input your seed into any websites that you don’t trust.
Is Someone Going To Guess My IOTA Seed?
What are the odds of someone guessing your seed?
  • IOTA seed = 81 characters long, and you can use A-Z, 9
  • Giving 2781 = 8.7x10115 possible combinations for IOTA seeds
  • Now let's say you have a "super computer" letting you generate and read every address associated with 1 trillion different seeds per second.
  • 8.7x10115 seeds / 1x1012 generated per second = 8.7x10103 seconds = 2.8x1096 years to process all IOTA seeds.

Why does balance appear to be 0 after a snapshot?

When a snapshot happens, all transactions are being deleted from the Tangle, leaving only the record of how many IOTA are owned by each address. However, the next time the wallet scans the Tangle to look for used addresses, the transactions will be gone because of the snapshot and the wallet will not know anymore that an address belongs to it. This is the reason for the need to regenerate addresses, so that the wallet can check the balance of each address. The more transactions were made before a snapshot, the further away the balance moves from address index 0 and the more addresses have to be (re-) generated after the snapshot.

What happens if you reuse an address?

It is important to understand that only outgoing transactions reveal the private key and incoming transactions do not. If you somehow manage to receive iotas using an address after having used it previously to send iotas—let's say your friend sends iotas to an old address of yours—these iotas may be at risk.
Recall that after a single use an iota address still has the equivalent of 256-bit security (like Bitcoin) so technically, the iotas will still be safe if you do not try to send them out. However, you would want to move these iotas out eventually and the moment you try to send them out, your private key will be revealed a second time and it now becomes feasible for an attacker to brute-force the private key. If someone is monitoring your address and spots a second use, they can easily crack the key and then use it to make a second transaction that will compete with yours. It then becomes a race to see whose transaction gets confirmed first.
Note: The current wallet prevents you from reusing an address to make a second transaction so any iotas you receive with a 'used' address will be stuck. This is a feature of wallet and has nothing to do with the fundamental workings of IOTA.

Sending IOTA

What does attach to the tangle mean?

The process of making an transaction can be divided into two main steps:
  1. The local signing of a transaction, for which your seed is required.
  2. Taking the prepared transaction data, choosing two transactions from the tangle and doing the POW. This step is also called “attaching”.
The following analogy makes it easier to understand:
Step one is like writing a letter. You take a piece of paper, write some information on it, sign it at the bottom with your signature to authenticate that it was indeed you who wrote it, put it in an envelope and then write the recipient's address on it.
Step two: In order to attach our “letter” (transaction), we go to the tangle, pick randomly two of the newest “letters” and tie a connection between our “letter” and each of the “letters” we choose to reference.
The “Attach address” function in the wallet is actually doing nothing else than making an 0 value transaction to the address that is being attached.

Why is my transaction pending?

IOTA's current Tangle implementation (IOTA is in constant development, so this may change in the future) has a confirmation rate that is ~66% at first attempt.
So, if a transaction does not confirm within 1 hour, it is necessary to "reattach" (also known as "replay") the transaction one time. Doing so one time increases probability of confirmation from ~66% to ~89%.
Repeating the process a second time increases the probability from ~89% to ~99.9%.

How do I reattach a transaction.

Reattaching a transaction is different depending on where you send your transaction from. To reattach using the GUI Desktop wallet follow these steps:
  1. Click 'History'.
  2. Click 'Show Bundle' on the 'pending' transaction.
  3. Click 'Reattach'.
  4. Click 'Rebroadcast'. (optional, usually not required)
  5. Wait 1 Hour.
  6. If still 'pending', repeat steps 1-5 once more.

Does the private key get revealed each time you reattach a transaction?

When you use the reattach function in the desktop wallet, a new transaction will be created but it will have the same signature as the original transaction and hence, your private key will not revealed a second time.

What happens to pending transactions after a snapshot?

IOTA Network and Nodes

What incentives are there for running a full node?

IOTA is made for m2m economy, once wide spread adoption by businesses and the IOT, there will be a lot of investment by these businesses to support the IOTA network. In the meantime if you would like to help the network and speed up p2p transactions at your own cost, you can support the IOTA network by setting up a Full Node.
Running a full node also means you don't have to trust a 3rd party light node provider. By running a full node you get to take advantage of new features that might not be installed on 3rd party nodes.

How to set up a full node?

To set up a full node you will need to follow these steps:
  1. Download the full node software: either GUI, or headless CLI for lower system requirements and better performance.
  2. Get a static IP for your node.
  3. Join the network by adding 7-9 neighbours.
  4. Keep your full node up and running as much as possible.
A detailed user guide on how to set up a VTS IOTA Full Node from scratch can be found here.

How do I get a static IP?

To learn how to setup a hostname (~static IP) so you can use the newest IOTA versions that have no automated peer discovery please follow this guide.

The core concepts of DTube's new blockchain

Dear Reddit community,
Following our announcement for DTube v0.9, I have received countless questions about the new blockchain part, avalon. First I want to make it clear, that it would have been utterly impossible to build this on STEEM, even with the centralized SCOT/Tribes that weren't available when I started working on this. This will become much clearer as you read through the whole wall of text and understand the novelties.
SteemPeak says this is a 25 minutes read, but if you are truly interested in the concept of a social blockchain, and you believe in its power, I think it will be worth the time!

MOVING FORWARD

I'm a long time member of STEEM, with tens of thousands of staked STEEM for 2 years+. I understand the instinctive fear from the other members of the community when they see a new crypto project coming out. We've had two recent examples recently with the VOICE and LIBRA annoucements, being either hated or ignored. When you are invested morally, and financially, when you see competitors popping up, it's normal to be afraid.
But we should remember competition is healthy, and learn from what these projects are doing and how it will influence us. Instead, by reacting the way STEEM reacts, we are putting our heads in the sand and failing to adapt. I currently see STEEM like the "North Korea of blockchains", trying to do everything better than other blockchains, while being #80 on coinmarketcap and slowly but surely losing positions over the months.
When DLive left and revealed their own blockchain, it really got me thinking about why they did it. The way they did it was really scummy and flawed, but I concluded that in the end it was a good choice for them to try to develop their activity, while others waited for SMTs. Sadly, when I tried their new product, I was disappointed, they had botched it. It's purely a donation system, no proof of brain... And the ultra-majority of the existing supply is controlled by them, alongside many other 'anti-decentralization' features. It's like they had learnt nothing from their STEEM experience at all...
STEEM was still the only blockchain able to distribute crypto-currency via social interactions (and no, 'donations' are not social interactions, they are monetary transfers; bitcoin can do it too). It is the killer feature we need. Years of negligence or greed from the witnesses/developers about the economic balance of STEEM is what broke this killer feature. Even when proposing economical changes (which are actually getting through finally in HF21), the discussions have always been centered around modifying the existing model (changing the curve, changing the split, etc), instead of developing a new one.
You never change things by fighting the existing reality.
To change something, build a new model that makes the existing model obsolete.
What if I built a new model for proof of brain distribution from the ground up? I first tried playing with STEEM clones, I played with EOS contracts too. Both systems couldn't do the concepts I wanted to integrate for DTube, unless I did a major refactor of tens of thousands of lines of code I had never worked with before. Making a new blockchain felt like a lighter task, and more fun too.
Before even starting, I had a good idea of the concepts I'd love to implement. Most of these bullet points stemmed from observations of what happened here on STEEM in the past, and what I considered weaknesses for d.tube's growth.

NO POWER-UP

The first concept I wanted to implement deep down the core of how a DPOS chain works, is that I didn't want the token to be staked, at all (i.e. no 'powering up'). The cons of staking for a decentralized social platform are obvious: * complexity for the users with the double token system. * difficulty to onboard people as they need to freeze their money, akin to a pyramid scheme.
The only good thing about staking is how it can fill your bandwidth and your voting power when you power-up, so you don't need to wait for it to grow to start transacting. In a fully-liquid system, your account ressources start at 0% and new users will need to wait for it to grow before they can start transacting. I don't think that's a big issue.
That meant that witness elections had to be run out of the liquid stake. Could it be done? Was it safe for the network? Can we update the cumulative votes for witnesses without rounding issues? Even when the money flows between accounts freely?
Well I now believe it is entirely possible and safe, under certain conditions. The incentive for top witnesses to keep on running the chain is still present even if the stake is liquid. With a bit of discrete mathematics, it's easy to have a perfectly deterministic algorithm to run a decentralized election based off liquid stake, it's just going to be more dynamic as the funds and the witness votes can move around much faster.

NO EARLY USER ADVANTAGE

STEEM has had multiple events that influenced the distribution in a bad way. The most obvious one is the inflation settings. One day it was hella-inflationary, then suddently hard fork 16 it wasn't anymore. Another major one, is the non-linear rewards that ran for a long time, which created a huge early-user advantage that we can still feel today.
I liked linear rewards, it's what gives minnows their best chance while staying sybil-resistant. I just needed Avalon's inflation to be smart. Not hyper-inflationary like The key metric to consider for this issue, is the number of tokens distributed per user per day. If this metric goes down, then the incentive for staying on the network and playing the game, goes down everyday. You feel like you're making less and less from your efforts. If this metric goes up, the number of printed tokens goes up and the token is hyper-inflationary and holding it feels really bad if you aren't actively earning from the inflation by playing the game.
Avalon ensures that the number of printed tokens is proportional to the number of users with active stake. If more users come in, avalon prints more tokens, if users cash-out and stop transacting, the inflation goes down. This ensures that earning 1 DTC will be about as hard today, tomorrow, next month or next year, no matter how many people have registered or left d.tube, and no matter what happens on the markets.

NO LIMIT TO MY VOTING POWER

Another big issue that most steemians don't really know about, but that is really detrimental to STEEM, is how the voting power mana bar works. I guess having to manage a 2M SP delegation for @dtube really convinced me of this one.
When your mana bar is full at 100%, you lose out the potential power generation, and rewards coming from it. And it only takes 5 days to go from 0% to 100%. A lot of people have very valid reasons to be offline for 5 days+, they shouldn't be punished so hard. This is why all most big stake holders make sure to always spend some of their voting power on a daily basis. And this is why minnows or smaller holders miss out on tons of curation rewards, unless they delegate to a bidbot or join some curation guild... meh. I guess a lot of people would rather just cash-out and don't mind the trouble of having to optimize their stake.
So why is it even a mana bar? Why can't it grow forever? Well, everything in a computer has to have a limit, but why is this limit proportional to my stake? While I totally understand the purpose of making the bandwidth limited and forcing big stake holders to waste it, I think it's totally unneeded and inadapted for the voting power. As long as the growth of the VP is proportional to the stake, the system stays sybil-resistant, and there could technically be no limit at all if it wasn't for the fact that this is ran in a computer where numbers have a limited number of bits.
On Avalon, I made it so that your voting power grows virtually indefinitely, or at least I don't think anyone will ever reach the current limit of Number.MAX_SAFE_INTEGER: 9007199254740991 or about 9 Peta VP. If you go inactive for 6 months on an account with some DTCs, when you come back you will have 6 months worth of power generation to spend, turning you into a whale, at least for a few votes.
Another awkward limit on STEEM is how a 100% vote spends only 2% of your power. Not only STEEM forces you to be active on a daily basis, you also need to do a minimum of 10 votes / day to optimize your earnings. On Avalon, you can use 100% of your stored voting power in a single mega-vote if you wish, it's up to you.

A NEW PROOF-OF-BRAIN

No Author rewards

People should vote with the intent of getting a reward from it. If 75% of the value forcibly goes to the author, it's hard to expect a good return from curation. Steem is currently basically a complex donation platform. No one wants to donate when they vote, no matter what they will say, and no matter how much vote-trading, self-voting or bid-botting happens.
So in order to keep a system where money is printed when votes happen, if we cannot use the username of the author to distribute rewards, the only possibility left is to use the list of previous voters aka "Curation rewards". The 25% interesting part of STEEM, that has totally be shadowed by the author rewards for too long.

Downvote rewards

STEEM has always suffered from the issue that the downvote button is unused, or when it's used, it's mostly for evil. This comes from the fact that in STEEM's model, downvotes are not eligible for any rewards. Even if they were, your downvote would be lowering the final payout of the content, and your own curation rewards...
I wanted Avalon's downvotes to be completely symmetric to the upvotes. That means if we revert all the votes (upvotes become downvotes and vice versa), the content should still distribute the same amount of tokens to the same people, at the same time.

No payment windows

Steem has a system of payments windows. When you publish a content, it opens a payment window where people can freely upvote or downvote to influence the payout happening 7 days later. This is convenient when you want a system where downvotes lower rewards. Waiting 7 days to collect rewards is also another friction point for new users, some of them might never come back 7 days later to convince themselves that 'it works'. On avalon, when you are part of the winners of curation after a vote, you earn it instantly in your account, 100% liquid and transferable.

Unlimited monetization in time

Indeed, the 7 days monetization limit has been our biggest issue for our video platform since day 8. This incentivized our users to create more frequent, but lesser quality content, as they know that they aren't going to earn anything from the 'long-haul'. Monetization had to be unlimited on DTube, so that even a 2 years old video could be dug up and generate rewards in the far future.
Infinite monetization is possible, but as removing tokens from a balance is impossible, the downvotes cannot remove money from the payout like they do on STEEM. Instead, downvotes print money in the same way upvotes do, downvotes still lower the popularity in the hot and trending and should only rewards other people who downvoted the same content earlier.

New curation rewards algorithm

STEEM's curation algorithm isn't stupid, but I believe it lacks some elegance. The 15 minutes 'band-aid' necessary to prevent curation bots (bots who auto vote as fast as possible on contents of popular authors) that they added proves it. The way is distributes the reward also feels very flat and boring. The rewards for my votes are very predictable, especially if I'm the biggest voter / stake holder for the content. My own vote is paying for my own curation rewards, how stupid is that? If no one elses votes after my big vote despite a popularity boost, it probably means I deserve 0 rewards, no?
I had to try different attempts to find an algorithm yielding interesting results, with infinite monetization, and without obvious ways to exploit it. The final distribution algorithm is more complex than STEEM's curation but it's still pretty simple. When a vote is cast, we calculate the 'popularity' at the time of the vote. The first vote is given a popularity of 0, the next votes are defined by (total_vp_upvotes - total_vp_downvotes) / time_since_1st_vote. Then we look into the list of previous votes, and we remove all votes in the opposite direction (up/down). The we remove all the votes with a higher popularity if its an upvote, or the ones with a lower popularity if its a downvote. The remaining votes in the list are the 'winners'. Finally, akin to STEEM, the amount of tokens generated by the vote will be split between winners proportionally to the voting power spent by each (linear rewards - no advantages for whales) and distributed instantly. Instead of purely using the order of the votes, Avalon distribution is based on when the votes are cast, and each second that passes reduces the popularity of a content, potentially increasing the long-term ROI of the next vote cast on it.
Graph It's possible to chart the popularity that influences the DTC monetary distribution directly in the d.tube UI
This algorithm ensures there are always losers. The last upvoter never earns anything, also the person who upvoted at the highest popularity, and the one who downvoted at the lowest popularity would never receive any rewards for their vote. Just like the last upvoter and last downvoter wouldn't either. All the other ones in the middle may or may not receive anything, depending on how the voting and popularity evolved in time. The one with an obvious advantage, is the first voter who is always counted as 0 popularity. As long as the content stays at a positive popularity, every upvote will earn him rewards. Similarly, being the first downvoter on an overly-popular content could easily earn you 100% rewards on the next downvote that could be from a whale, earning you a fat bonus.
While Avalon doesn't technically have author rewards, the first-voter advantage is strong, and the author has the advantage of always being the first voter, so the author can still earn from his potentially original creations, he just needs to commit some voting power on his own contents to be able to publish.

ONE CHAIN <==> ONE APP

More scalable than shared blockchains

Another issue with generalistic blockchains like ETH/STEEM/EOS/TRX, which are currently hosting dozens of semi-popular web/mobile apps, is the reduced scalability of such shared models. Again, everything in a computer has a limit. For DPOS blockchains, 99%+ of the CPU load of a producing node will be to verify the signatures of the many transactions coming in every 3 seconds. And sadly this fact will not change with time. Even if we had a huge breakthrough on CPU speeds today, we would need to update the cryptographic standards for blockchains to keep them secure. This means it would NOT become easier to scale up the number of verifiable transactions per seconds.
Oh, but we are not there yet you're thinking? Or maybe you think that we'll all be rich if we reach the scalability limits so it doesn't really matter? WRONG
The limit is the number of signature verifications the most expensive CPU on the planet can do. Most blockchains use the secp256k1 curve, including Bitcoin, Ethereum, Steem and now Avalon. It was originally chosen for Bitcoin by Satoshi Nakamoto probably because it's decently quick at verifying signatures, and seems to be backdoor-proof (or else someone is playing a very patient game). Maybe some other curves exist with faster signature verification speed, but it won't be improved many-fold, and will likely require much research, auditing, and time to get adopted considering the security implications.
In 2015 Graphene was created, and Bitshares was completely rewritten. This was able to achieve 100,000 transaction per second on a single machine, and decentralized global stress testing achieved 18,000 transactions per second on a distributed network.
So BitShares/STEEM and other DPOS graphene chains in production can validate at most 18000 txs/sec, so about 1.5 billion transactions per day. EOS, Tendermint, Avalon, LIBRA or any other DPOS blockchain can achieve similar speeds, because there's no planet-killing proof-of-works, and thanks to the leader-based/democratic system that reduces the number of nodes taking part in the consensus.
As a comparison, there are about 4 billion likes per day on instagram, so you can probably double that with the actual uploads, stories and comments, password changes, etc. The load is also likely unstable through the day, probably some hours will go twice as fast as the average. You wouldn't be able to fit Instagram in a blockchain, ever, even with the most scalable blockchain tech on the world's best hardware. You'd need like a dozen of those chains. And instagram is still a growing platform, not as big as Facebook, or YouTube.
So, splitting this limit between many popular apps? Madness! Maybe it's still working right now, but when many different apps reach millions of daily active users plus bots, it won't fit anymore.
Serious projects with a big user base will need to rethink the shared blockchain models like Ethereum, EOS, TRX, etc because the fees in gas or necessary stake required to transact will skyrocket, and the victims will be the hordes of minnows at the bottom of the distribution spectrum.
If we can't run a full instagram on a DPOS blockchain, there is absolutely no point trying to run medium+reddit+insta+fb+yt+wechat+vk+tinder on one. Being able to run half an instagram is already pretty good and probably enough to actually onboard a fair share of the planet. But if we multiply the load by the number of different app concepts available, then it's never gonna scale.
DTube chain is meant for the DTube UI only. Please do not build something unrelated to video connecting to our chain, we would actively do what we can to prevent you from growing. We want this chain to be for video contents only, and the JSON format of the contents should always follow the one used by d.tube.
If you are interested in avalon tech for your project isn't about video, it's strongly suggested to fork the blockchain code and run your own avalon chain with a different origin id, instead of trying to connect your project to dtube's mainnet. If you still want to do it, chain leaders would be forced to actively combat your project as we would consider it as useless noise inside our dedicated blockchain.

Focused governance

Another issue of sharing a blockchain, is the issues coming up with the governance of it. Tons of features enabled by avalon would be controversial to develop on STEEM, because they'd only benefit DTube, and maybe even hurt/break some other projects. At best they'd be put at the bottom of a todo list somewhere. Having a blockchain dedicated to a single project enables it to quickly push updates that are focused on a single product, not dozens of totally different projects.
Many blockchain projects are trying to make decentralized governance true, but this is absolutely not what I am interested in for DTube. Instead, in avalon the 'init' account, or 'master' account, has very strong permissions. In the DTC case, @dtube: * will earn 10% fees from all the inflation * will not have to burn DTCs to create accounts * will be able to do certain types of transactions when others can't * * account creation (during steem exclusivity period) * * transfers (during IEO period) * * transfering voting power and bandwidth ressources (used for easier onboarding)
For example, for our IEO we will setup a mainnet where only @dtube is allowed to transfer funds or vote until the IEO completes and the airdrop happens. This is also what enabled us to create a 'steem-only' registration period on the public testnet for the first month. Only @dtube can create accounts, this way we can enforce a 1 month period where users can port their username for free, without imposters having a chance to steal usernames. Through the hard-forking mechanism, we can enable/disable these limitations and easily evolve the rules and permissions of the blockchain, for example opening monetary transfers at the end of our IEO, or opening account creation once the steem exclusivity ends.
Luckily, avalon is decentralized, and all these parameters (like the @dtube fees, and @dtube permissions) are easily hardforkable by the leaders. @dtube will however be a very strong leader in the chain, as we plan to use our vote to at least keep the #1 producing node for as long as we can.
We reserve the right to 'not follow' an hardfork. For example, it's obvious we wouldn't follow something like reducing our fees to 0% as it would financially endanger the project, and we would rather just continue our official fork on our own and plug d.tube domain and mobile app to it.
On the other end of the spectrum, if other leaders think @dtube is being tyranical one way or another, leaders will always have the option of declining the new hardforks and putting the system on hold, then @dtube will have an issue and will need to compromise or betray the trust of 1/3 of the stake holders, which could reveal costly.
The goal is to have a harmounious, enterprise-level decision making within the top leaders. We expect these leaders to be financially and emotionally connected with the project and act for good. @dtube is to be expected to be the main good actor for the chain, and any permission given to it should be granted with the goal of increasing the DTC marketcap, and nothing else. Leaders and @dtube should be able to keep cooperation high enough to keep the hard-forks focused on the actual issues, and flowing faster than other blockchain projects striving for a totally decentralized governance, a goal they are unlikely to ever achieve.

PERFECT IMBALANCE

A lot of hard-forking

Avalon is easily hard-forkable, and will get hard-forked often, on purpose. No replays will be needed for leaders/exchanges during these hard-forks, just pull the new hardfork code, and restart the node before the hard-fork planned time to stay on the main fork. Why is this so crucial? It's something about game theory.
I have no former proof for this, but I assume a social and financial game akin to the one played on steem since 2016 to be impossible to perfectly balance, even with a thourough dichotomical process. It's probably because of some psychological reason, or maybe just the fact that humans are naturally greedy. Or maybe it's just because of the sheer number of players. They can gang up together, try to counter each others, and find all sorts of creative ideas to earn more and exploit each other. In the end, the slightest change in the rules, can cause drastic gameplay changes. It's a real problem, luckily it's been faced by other people in the past.
Similarly to what popular and succesful massively multiplayer games have achieved, I plan to patch or suggest hard-forks for avalon's mainnet on a bi-monthly basis. The goal of this perfect imbalance concept, is to force players to re-discover their best strategy often. By introducing regular, small, and semi-controlled changes into this chaos, we can fake balance. This will require players to be more adaptative and aware of the changes. This prevents the game from becoming stale and boring for players, while staying fair.

Death to bots

Automators on the other side, will need to re-think their bots, go through the developement and testing phase again, on every new hard-fork. It will be an unfair cat-and-mouse game. Doing small and semi-random changes in frequent hard-forks will be a easy task for the dtube leaders, compared to the work load generated to maintain the bots. In the end, I hope their return on investment to be much lower compared to the bid-bots, up to a point where there will be no automation.
Imagine how different things would have been if SteemIt Inc acted strongly against bid-bots or other forms of automation when they started appearing? Imagine if hard-forks were frequent and they promised to fight bid-bots and their ilk? Who would be crazy enough to make a bid-bot apart from @berniesanders then?
I don't want you to earn DTCs unless you are human. The way you are going to prove you are human, is not by sending a selfie of you with your passport to a 3rd party private company located on the other side of the world. You will just need to adapt to the new rules published every two weeks, and your human brain will do it subconsciously by just playing the voting game and seeing the rewards coming.
All these concepts are aimed at directly improving d.tube, making it more resilient, and scale both technologically and economically. Having control over the full tech stack required to power our dapp will prevent issues like the one we had with the search engine, where we relied too heavily on a 3rd party tool, and that created a 6-months long bug that basically broke 1/3 of the UI.
While d.tube's UI can now totally run independently from any other entity, we kept everything we could working with STEEM, and the user is now able to transparently publish/vote/comment videos on 2 different chains with one click. This way we can keep on leveraging the generalistic good features of STEEM that our new chain doesn't focuses on doing, such as the dollar-pegged token, the author rewards/donation mechanism, the tribes/communities tokens, and simply the extra exposure d.tube users can get from other website (steemit.com, busy.org, partiko, steempeak, etc), which is larger than the number of people using d.tube directly.
The public testnet has been running pretty well for 3 weeks now, with 6000+ accounts registered, and already a dozen of independant nodes popping up and running for leaders. The majority of the videos are cross-posted on both chains and the daily video volume has slightly increased since the update, despite the added friction of the new 'double login' system and several UI bugs.
If you've read this article, I'm hoping to get some reactions from you in the comments section!
Some even more focused articles about avalon are going to pop on my blog in the following weeks, such as how to get a node running and running for leadewitness, so feel free to follow me to get more news and help me reach 10K followers ;)

An in-depth overview of different mobile wallets

Disclaimer: A lot of time went into writing this and more research than I anticipated. Errors are not just possible, they are certain. If you find any mistakes, please reach out to me and I'll edit. Furthermore I know I probably missed a couple apps, there are a lot out there. If I missed a big one, then again contact me and I'll consider adding it. If you are reading this in the future, note that these apps update regularly, anything mentioned here may have changed by the time you are reading it.

What is a mobile wallet?

A mobile Bitcoin wallet is an application for a mobile device which acts as a lightweight wallet and allows you to store, send and receive Bitcoin (or other cryptocurrencies and tokens). Mobile wallets use SPV (Simplified Payment Verification) to allow wallet functionality without having to download the whole blockchain. This is very important as barely any mobile phones have enough storage space required for the full blockchain. Mobile wallets are also considered hotwallets, meaning they have an active connection to the internet. The mere fact of being 'online' allows for a number of attack vectors and as such should never be used to store large amounts. It is however not unsafe per se. Private keys are stored locally and encrypted. Some wallets keep backups of those encrypted private keys on a server of their own, and this is something to take note of, but not to fear. So without further ado, lets get to it. I focused on Android wallets, but many of the wallets mentioned here have iOS versions.

Wallet Breakdown

Samourai

Samourai focusses heavily on anonymity and obfuscation. Addresses are never used more than once. When making a transaction there is an obfuscation slider. Samourai has had SegWit enabled since October. Furthermore it offers a plethora of different features, too much to sum up here. If you are an advanced crypto-user you should definitely check out this wallet and their website which explains all of the different features. The UI takes a bit of getting used to though.

Breadwallet

Breadwallet is a very simple to use, straightforward app. The UI is slick and intuitive and in-app support to basic questions is very well incorporated. This could be a good wallet for a new person to the scene. The lack of advanced features will make this app not the go-to for more experienced users. It does however feature fingerprint authentication, which is cool, as well as BCH extraction. The lack of SegWit and complete absence of custom fee's is a problem though, especially since fees have gone up during the recent BTC spike. With only 2 fee options to choose from I simply can not recommend this wallet to people who are looking to make frequent transactions.

GreenAddress

When I first started with Greenaddress I didn't like the UI, I found it a bit clumsy. So definitely not user-friendly for a beginner. On the plus side it allows a choice of 2FA settings. Furthermore it has SegWit enabled and it has some advanced features like nLockTime transactions and it offers a service for instant transactions. This all feels very Lightning Network-y, which makes sense as GreenAddress is a part of Blockstream. Our friends in the other sub will most likely have something to say about this. I'll refrain from this and just say the following: this is an advanced wallet with promising features. If they clean up their UI a bit I could see myself using this without hesitation. The fact that they have MultiSig is a big plus as most mobile wallets do not have this functionality.

AirBitz

Unlike any other wallet I fired up at that point, this app did not prompt me with a 12- or 24-word seed. Instead it made me make an account, the regular username/password combo. After some research I found that these are not stored in a local database on their end. Which means that recovering your password in case of loss like with every other username/password login method we are so used to, is not possible. It is merely a different representation of an encryption key, allowing you access to your private keys. It features some interesting stuff though, NFC-compliant transactions and Bluetooth Low Energy (BLE) for example. Clearly this app is meant to be a bridge between users and merchants and has focus on making regular in-person transactions. Thus it mimics some non-crypto related payment apps that we have. Personally, I am not a fan, but I can appreciate the design philosophy and I would't be surprised if their design model worked very well in the future with the LN or with other crypto's that focus on small payments. As for the UI, it's fairly simple, yet horribly cluttered with partnered services. Good for non-techies maybe, but not for more experienced crypto-enthusiasts.

Electrum

Much like the desktop wallet I used years ago when I first started with Bitcoin, the mobile wallet is minimal. Straightforward and without fancy colors or UI. For those of us who have known the internet before Facebook, this app will feel strangely familiar. This is a classic example of a no-nonsense wallet with the features that really matter. SegWit and MultiSig enabled. A further lack of advanced options might be a turn-off for some users out there though. I did however find the option to spend coins from unconfirmed transactions. This could be very useful in case you want to cancel out a previously stuck or erroneous transaction and ensure it's never cleared. One downside to this wallet is the very primitive way of setting a custom fee. No guidelines, scrollwheel or info. Just a simple box in which to put your fee which won't help intermediate users, only experienced users.
Edit: sidenote on the SegWit implementation by Electrum http://www.crypto-economy.net/electrum-3-0-enables-bech32-segwit-addresses/?lang=en

CoPay

Of all the apps I've tried up to this point, CoPay had the best initializing phase, succinctly explaining risk and security. I can not imagine a better intro to a wallet for a first time bitcoiner. It being of a product of BitPay, of which I am personally not a fan, I have to admit though. This app looks clean, feels fast and is easy to use. It successfully demystified MultiSig functionality in its UI and partnered services are not obtrusive in the design. Downsides are lack of fee setting possibilities and SegWit. The latter I really do not understand given their main core of business. If it wasn't for those last two points, I would not see why not to recommend this wallet.

ArcBit

This app dissapointed me a bit. It starts out of the box, not mentioning any backup seeds or tutorial on the wallet itself or Bitcoin. It has no SegWit, no MultiSig, a lack of features and whilst a backup seed can still be requested from the settings, I feel it is of the utmost importance that such a security measure is not quickly overlooked. The lack of fee management tops it off. While this wallet works just fine and looks just fine, there are too many alternatives out there with better options and functionality for me to ever advise anyone to use this wallet.

CoinSpace

CoinSpace is one of those apps that could be really cool, but completely missed the boat on some other design choices. In-app ads unless you pay 1.6$ or something. Settings hidden behind a CoinSpace login screen. It features multiple tokens though with built in conversion through ShapeShift, which could have been awesome. But the excessive ads are just a big no-no. Lack of SegWit and limited fee options make this one of the least interesting wallets out there.

Simple Bitcoin Wallet

Simple Bitcoin is a very basic, barebone wallet. Feels like a one-man project. Almost no settings possible at all. There's much better out there.

Bither

I oddly liked Bither because of its design that reminded me of websites from the 2005-ish era using lots of gradients. Its one of those apps that you either like or you don't. The UI is not bad, but could be better, there's some functionality hidden in the settings, but not enough to satisfy. One very useful feature is built in BCH and BCG extraction. This is the first app I encountered with built in Bitcoin Go
