Crypto-Powered - The Most Promising Use-Cases of Decentralized Finance (DeFi)

Crypto-Powered - The Most Promising Use-Cases of Decentralized Finance (DeFi)
A whirlwind tour of Defi, paying close attention to protocols that we’re leveraging at Genesis Block.
https://reddit.com/link/hrrt21/video/cvjh5rrh12b51/player
This is the third post of Crypto-Powered — a new series that examines what it means for Genesis Block to be a digital bank that’s powered by crypto, blockchain, and decentralized protocols.
Last week we explored how building on legacy finance is a fool’s errand. The future of money belongs to those who build with crypto and blockchain at their core. We also started down the crypto rabbit hole, introducing Bitcoin, Ethereum, and DeFi (decentralized finance). That post is required reading if you hope to glean any value from the rest of this series.
97% of all activity on Ethereum in the last quarter has been DeFi-related. The total value sitting inside DeFi protocols is roughly $2B — double what it was a month ago. The explosive growth cannot be ignored. All signs suggest that Ethereum & DeFi are a Match Made in Heaven, and both on their way to finding strong product/market fit.
So in this post, we’re doing a whirlwind tour of DeFi. We look at specific examples and use-cases already in the wild and seeing strong growth. And we pay close attention to protocols that Genesis Block is integrating with. Alright, let’s dive in.

Stablecoins

Stablecoins are exactly what they sound like: cryptocurrencies that are stable. They are not meant to be volatile (like Bitcoin). These assets attempt to peg their price to some external reference (eg. USD or Gold). A non-volatile crypto asset can be incredibly useful for things like merchant payments, cross-border transfers, or storing wealth — becoming your own bank but without the stress of constant price volatility.
There are major governments and central banks that are experimenting with or soon launching their own stablecoins like China with their digital yuan and the US Federal Reserve with their digital dollar. There are also major corporations working in this area like JP Morgan with their JPM Coin, and of course Facebook with their Libra Project.
Stablecoin activity has grown 800% in the last year, with $290B of transaction volume (funds moving on-chain).
The most popular USD-pegged stablecoins include:
  1. Tether ($10B): It’s especially popular in Asia. It’s backed by USD in a bank account. But given their lack of transparency and past controversies, they generally aren’t trusted as much in the West.
  2. USDC ($1B): This is the most reputable USD-backed stablecoin, at least in the West. It was created by Coinbase & Circle, both well-regarded crypto companies. They’ve been very open and transparent with their audits and bank records.
  3. DAI ($189M): This is backed by other crypto assets — not USD in a bank account. This was arguably the first true DeFi protocol. The big benefit is that it’s more decentralized — it’s not controlled by any single organization. The downside is that the assets backing it can be volatile crypto assets (though it has mechanisms in place to mitigate that risk).
Other notable USD-backed stablecoins include PAX, TrueUSD, Binance USD, and Gemini Dollar.
tablecoins are playing an increasingly important role in the world of DeFi. In a way, they serve as common pipes & bridges between the various protocols.

Lending & Borrowing

Three of the top five DeFi protocols relate to lending & borrowing. These popular lending protocols look very similar to traditional money markets. Users who want to earn interest/yield can deposit (lend) their funds into a pool of liquidity. Because it behaves similarly to traditional money markets, their funds are not locked, they can withdraw at any time. It’s highly liquid.
Borrowers can tap into this pool of liquidity and take out loans. Interest rates depend on the utilization rate of the pool — how much of the deposits in the pool have already been borrowed. Supply & demand. Thus, interest rates are variable and borrowers can pay their loans back at any time.
So, who decides how much a borrower can take? What’s the process like? Are there credit checks? How is credit-worthiness determined?
These protocols are decentralized, borderless, permissionless. The people participating in these markets are from all over the world. There is no simple way to verify identity or check credit history. So none of that happens.
Credit-worthiness is determined simply by how much crypto collateral the borrower puts into the protocol. For example, if a user wants to borrow $5k of USDC, then they’ll need to deposit $10k of BTC or ETH. The exact amount of collateral depends on the rules of the protocol — usually the more liquid the collateral asset, the more borrowing power the user can receive.
The most prominent lending protocols include Compound, Aave, Maker, and Atomic Loans. Recently, Compound has seen meteoric growth with the introduction of their COMP token — a token used to incentivize and reward participants of the protocol. There’s almost $1B in outstanding debt in the Compound protocol. Mainframe is also working on an exciting protocol in this area and the latest iteration of their white paper should be coming out soon.
There is very little economic risk to these protocols because all loans are overcollateralized.
I repeat, all loans are overcollateralized. If the value of the collateral depreciates significantly due to price volatility, there are sophisticated liquidation systems to ensure the loan always gets paid back.

Investments

Buying, selling, and trading crypto assets is certainly one form of investing (though not for the faint of heart). But there are now DeFi protocols to facilitate making and managing traditional-style investments.
Through DeFi, you can invest in Gold. You can invest in stocks like Amazon and Apple. You can short Tesla. You can access the S&P 500. This is done through crypto-based synthetics — which gives users exposure to assets without needing to hold or own the underlying asset. This is all possible with protocols like UMA, Synthetix, or Market protocol.
Maybe your style of investing is more passive. With PoolTogether , you can participate in a no-loss lottery.
Maybe you’re an advanced trader and want to trade options or futures. You can do that with DeFi protocols like Convexity, Futureswap, and dYdX. Maybe you live on the wild side and trade on margin or leverage, you can do that with protocols like Fulcrum, Nuo, and DDEX. Or maybe you’re a degenerate gambler and want to bet against Trump in the upcoming election, you can do that on Augur.
And there are plenty of DeFi protocols to help with crypto investing. You could use Set Protocol if you need automated trading strategies. You could use Melonport if you’re an asset manager. You could use Balancer to automatically rebalance your portfolio.
With as little as $1, people all over the world can have access to the same investment opportunities and tools that used to be reserved for only the wealthy, or those lucky enough to be born in the right country.
You can start to imagine how services like Etrade, TD Ameritrade, Schwab, and even Robinhood could be massively disrupted by a crypto-native company that builds with these types of protocols at their foundation.

Insurance

As mentioned in our previous post, there are near-infinite applications one can build on Ethereum. As a result, sometimes the code doesn’t work as expected. Bugs get through, it breaks. We’re still early in our industry. The tools, frameworks, and best practices are all still being established. Things can go wrong.
Sometimes the application just gets in a weird or bad state where funds can’t be recovered — like with what happened with Parity where $280M got frozen (yes, I lost some money in that). Sometimes, there are hackers who discover a vulnerability in the code and maliciously steal funds — like how dForce lost $25M a few months ago, or how The DAO lost $50M a few years ago. And sometimes the system works as designed, but the economic model behind it is flawed, so a clever user takes advantage of the system— like what recently happened with Balancer where they lost $500k.
There are a lot of risks when interacting with smart contracts and decentralized applications — especially for ones that haven’t stood the test of time. This is why insurance is such an important development in DeFi.
Insurance will be an essential component in helping this technology reach the masses.
Two protocols that are leading the way on DeFi insurance are Nexus Mutual and Opyn. Though they are both still just getting started, many people are already using them. And we’re excited to start working with them at Genesis Block.
https://preview.redd.it/wf1xvq3z12b51.png?width=700&format=png&auto=webp&s=70db1e9587f57d0c470a4f9f4523c216929e1876

Exchanges & Liquidity

Decentralized Exchanges (DEX) were one of the first and most developed categories in DeFi. A DEX allows a user to easily exchange one crypto asset for another crypto asset — but without needing to sign up for an account, verify identity, etc. It’s all via decentralized protocols.
Within the first 5 months of 2020, the top 7 DEX already achieved the 2019 trading volume. That was $2.5B. DeFi is fueling a lot of this growth.
https://preview.redd.it/1dwvq4e022b51.png?width=700&format=png&auto=webp&s=97a3d756f60239cd147031eb95fc2a981db55943
There are many different flavors of DEX. Some of the early ones included 0x, IDEX, and EtherDelta — all of which had a traditional order book model where buyers are matched with sellers.
Another flavor is the pooled liquidity approach where the price is determined algorithmically based on how much liquidity there is and how much the user wants to buy. This is known as an AMM (Automated Market Maker) — Uniswap and Bancor were early leaders here. Though lately, Balancer has seen incredible growth due mostly to their strong incentives for participation — similar to Compound.
There are some DEXs that are more specialized — for example, Curve and mStable focus mostly only stablecoins. Because of the proliferation of these decentralized exchanges, there are now aggregators that combine and connect the liquidity of many sources. Those include Kyber, Totle, 1Inch, and Dex.ag.
These decentralized exchanges are becoming more and more connected to DeFi because they provide an opportunity for yield and earning interest.
Users can earn passive income by supplying liquidity to these markets. It usually comes in the form of sharing transaction fee revenue (Uniswap) or token rewards (Balancer).

Payments

As it relates to making payments, much of the world is still stuck on plastic cards. We’re grateful to partner with Visa and launch the Genesis Block debit card… but we still don’t believe that's the future of payments. We see that as an important bridge between the past (legacy finance) and the future (crypto).
Our first post in this series shared more on why legacy finance is broken. We talked about the countless unnecessary middle-men on every card swipe (merchant, acquiring bank, processor, card network, issuing bank). We talked about the slow settlement times.
The future of payments will be much better. Yes, it’ll be from a mobile phone and the user experience will be similar to ApplePay (NFC) or WePay (QR Code).
But more importantly, the underlying assets being moved/exchanged will all be crypto — digital, permissionless, and open source.
Someone making a payment at the grocery store check-out line will be able to open up Genesis Block, use contactless tech or scan a QR code, and instantly pay for their goods. All using crypto. Likely a stablecoin. Settlement will be instant. All the middlemen getting their pound of flesh will be disintermediated. The merchant can make more and the user can spend less. Blockchain FTW!
Now let’s talk about a few projects working in this area. The xDai Burner Wallet experience was incredible at the ETHDenver event a few years ago, but that speed came at the expense of full decentralization (can it be censored or shut down?). Of course, Facebook’s Libra wants to become the new standard for global payments, but many are afraid to give Facebook that much control (newsflash: it isn’t very decentralized).
Bitcoin is decentralized… but it’s slow and volatile. There are strong projects like Lightning Network (Zap example) that are still trying to make it happen. Projects like Connext and OmiseGo are trying to help bring payments to Ethereum. The Flexa project is leveraging the gift card rails, which is a nice hack to leverage existing pipes. And if ETH 2.0 is as fast as they say it will be, then the future of payments could just be a stablecoin like DAI (a token on Ethereum).
In a way, being able to spend crypto on daily expenses is the holy grail of use-cases. It’s still early. It hasn’t yet been solved. But once we achieve this, then we can ultimately and finally say goodbye to the legacy banking & finance world. Employees can be paid in crypto. Employees can spend in crypto. It changes everything.
Legacy finance is hanging on by a thread, and it’s this use-case that they are still clinging to. Once solved, DeFi domination will be complete.

Impact on Genesis Block

At Genesis Block, we’re excited to leverage these protocols and take this incredible technology to the world. Many of these protocols are already deeply integrated with our product. In fact, many are essential. The masses won’t know (or care about) what Tether, USDC, or DAI is. They think in dollars, euros, pounds and pesos. So while the user sees their local currency in the app, the underlying technology is all leveraging stablecoins. It’s all on “crypto rails.”
https://preview.redd.it/jajzttr622b51.png?width=700&format=png&auto=webp&s=fcf55cea1216a1d2fcc3bf327858b009965f9bf8
When users deposit assets into their Genesis Block account, they expect to earn interest. They expect that money to grow. We leverage many of these low-risk lending/exchange DeFi protocols. We lend into decentralized money markets like Compound — where all loans are overcollateralized. Or we supply liquidity to AMM exchanges like Balancer. This allows us to earn interest and generate yield for our depositors. We’re the experts so our users don’t need to be.
We haven’t yet integrated with any of the insurance or investment protocols — but we certainly plan on it. Our infrastructure is built with blockchain technology at the heart and our system is extensible — we’re ready to add assets and protocols when we feel they are ready, safe, secure, and stable. Many of these protocols are still in the experimental phase. It’s still early.
At Genesis Block we’re excited to continue to be at the frontlines of this incredible, innovative, technological revolution called DeFi.
---
None of these powerful DeFi protocols will be replacing Robinhood, SoFi, or Venmo anytime soon. They never will. They aren’t meant to! We’ve discussed this before, these are low-level protocols that need killer applications, like Genesis Block.
So now that we’ve gone a little deeper down the rabbit hole and we’ve done this whirlwind tour of DeFi, the natural next question is: why?
Why does any of it matter?
Most of these financial services that DeFi offers already exist in the real world. So why does it need to be on a blockchain? Why does it need to be decentralized? What new value is unlocked? Next post, we answer these important questions.

The Truth Behind Bitcoin

The Truth Behind Bitcoin

https://preview.redd.it/gn05azkm0wz41.jpg?width=1280&format=pjpg&auto=webp&s=107d712cd9c494984ebd99a29eacf7f145356e82
Last May 16, J.K. Rowling the popular author of the all-time bestseller series, Harry Potter, tweeted her followers asking to help her understand Bitcoin.

How can we explain Bitcoin to someone with zero knowledge of it easily?
Truth to be told, when I first encountered Bitcoin a few years ago, I wasn’t very much invested in the idea of it. I thought it was too technical, and it would be better to leave for the IT experts to enjoy its full features.
In our first two blog articles, we talked about cryptocurrencies in general, and how to secure these using cryptocurrency wallets. These two blogs are really helpful, especially those who are not yet familiar with cryptocurrencies.
Bitcoin in General
(See Bitcoin history here.)
Tracing back our history, people before didn’t need any central authority to pay or trade for something. Instead, they use gold or existing valuable possession in exchange for the things that they wanted. This is the basic ideology of Bitcoin. To be able to do transactions fast and easy again anytime and anywhere without any central authority through the use of modern technology.
Without getting too technical, Bitcoin solves the current difficulty of making financial transactions. At present, monetary transactions involve a third party (bank) and it comes along, most of the time, with exorbitant service fees. To put it simply, the peer-to-peer transaction is possible with the use of Bitcoin as people don’t need any central authority to confirm and verify their own monetary transactions.
Bitcoin transactions run in a blockchain, a decentralized ledger run by a peer-to-peer (P2P) network that processes and stores cryptocurrency transactions. Blockchain solves the digital transaction problems or double-spending that people are very afraid to encounter. Transactions within the blockchain use a special algorithm system that is stored in a “block” and linking or “chaining” them together after, thus making these records nearly impossible to get altered or change.
This technology makes Bitcoin transactions secure as each blockchain network have the same set of records of the entire blockchain data. It will be almost close to impossible to manipulate the system, as it requires the hacker to alter all the millions of blocks connected in the network, or else the other networks will reject his or her attempt as it doesn’t match with the existing records in the chain.
Bitcoin transactions can be viewed by everyone, as it has transparent ledger or blockchain, through a bitcoin address without revealing any of your identity and who is the person behind these transactions.
Bitcoin Supply
What makes Bitcoin unique is the fact that it only has a finite supply of 21 million. Unlike fiat currencies that can be printed out by the government anytime, Bitcoin’s prearranged supply makes technically scarce.
Bitcoin was first launched in 2009 and had a block subsidy of 50 BTC. In November 2012, the first Bitcoin halving commenced and reduced the 50 BTC subsidy to 25 BTC. It further dropped on the second halving in 2016 by 12.5 BTC per block. Recently, last May 12 of this year, people witnessed the third halving where BTC is further reduced to 6.25 per block.
Bitcoin halving, a pre-programmed event where the number of Bitcoin rewards per block is literally halved or divided by two, usually happens every four years. There are many theories as to why it was programmatically designed in such way. Nevertheless, this unique scarcity makes it more valuable as the more it becomes rare, the demand for it goes higher so does its price.
Where can I Spend Bitcoin?
Though the price of Bitcoin in the market is very volatile due to its relatively new system, Bitcoin is as good as your local currency which can be converted anytime. There are also a growing number of merchants and business who are embracing Bitcoin payments.
How to get a Bitcoin? There are a lot of free cryptocurrency wallets available in the market today. These wallets will help you generate your first Bitcoin address, which you can use for transactions. Some of these have instant Bitcoin to local currency exchanges, and also offer debit card services linked to their wallet, making it easier to spend.
Cryptocurrency wallets like Swipe offer a multi-asset digital wallet solution that supports Bitcoin together with other cryptocurrencies. Upon verification, Swipe users can buy, sell, and spend cryptocurrencies, including Bitcoin, within the app. It also has a Swipe Visa Card linked to its platform and has existing partnerships with Apple, Samsung, and Google Play, making it conveniently accessible for users across the world.
Swipe users can also enjoy up to five percent cashback paid in BTC as Swipe acknowledges the big role that Bitcoin played in the cryptocurrency industry.
Bitcoins paved the way for easier financial management. Through this discovery, people realized that there is a possibility of managing their own funds without going through any authorities to validate their transactions. Lastly, since this is a digital currency with no physical existence, people can find new solutions to further strengthen its security and accessibility. In time, people will realize the need for financial security upgrades on fiat currencies through the example given by the growth and expansion of Bitcoin and other cryptocurrencies.
How about you? How will you explain Bitcoin to peers who don’t understand it?

TKEYSPACE — blockchain in your mobile

TKEYSPACE — blockchain in your mobile

https://preview.redd.it/w8o3bcvjrtx41.png?width=1400&format=png&auto=webp&s=840ac3872156215b30e708920edbef4583190654
Someone says that the blockchain in the phone is marketing. This is possible for most applications, but not for Tkeycoin. Today we will talk about how the blockchain works in the TkeySpace app.
Who else is not in the topic, TkeySpace is a financial application for decentralized and efficient management of various cryptocurrencies, based on a distributed architecture without using a client-server.
In simple words, it is a blockchain in the user’s mobile device that excludes hacking and hacker attacks, and all data is encrypted using modern cryptographic methods.
https://preview.redd.it/8uku6thlrtx41.png?width=1280&format=png&auto=webp&s=e1a610244da53100a5bc6b821ee5c799c6493ac4

Blockchain

Let’s start with the most important thing — the blockchain works on the principles of P2P networks, when there is no central server and each device is both a server and a client, such an organization allows you to maintain the network performance with any number and any combination of available nodes.
For example, there are 12 machines in the network, and anyone can contact anyone. As a client (resource consumer), each of these machines can send requests for the provision of some resources to other machines within this network and receive them. As a server, each machine must process requests from other machines in the network, send what was requested, and perform some auxiliary and administrative functions.
With traditional client-server systems, we can get a completely disabled social network, messenger, or another service, given that we rely on a centralized infrastructure — we have a very specific number of points of failure. If the main data center is damaged due to an earthquake or any other event, access to information will be slowed down or completely disabled.
With a P2P solution, the failure of one network member does not affect the network operation in any way. P2P networks can easily switch to offline mode when the channel is broken — in which it will exist completely independently and without any interaction.
Instead of storing information in a single central point, as traditional recording methods do, multiple copies of the same data are stored in different locations and on different devices on the network, such as computers or mobile devices.

https://i.redd.it/2c4sv7rnrtx41.gif
This means that even if one storage point is damaged or lost, multiple copies remain secure in other locations. Similarly, if one part of the information is changed without the consent of the rightful owners, there are many other copies where the information is correct, which makes the false record invalid.
The information recorded in the blockchain can take any form, whether it is a transfer of money, ownership, transaction, someone’s identity, an agreement between two parties, or even how much electricity a light bulb used.
However, this requires confirmation from multiple devices, such as nodes in the network. Once an agreement, otherwise known as consensus, is reached between these devices to store something on the blockchain — it can’t be challenged, deleted, or changed.
The technology also allows you to perform a truly huge amount of computing in a relatively short time, which even on supercomputers would require, depending on the complexity of the task, many years or even centuries of work. This performance is achieved because a certain global task is divided into a large number of blocks, which are simultaneously performed by hundreds of thousands of devices participating in the project.

P2P messaging and syncing in TkeySpace

TkeySpace is a node of the TKEY network and other supported networks. when you launch the app, your mobile node connects to an extensive network of supported blockchains, syncs with full nodes to validate transactions and incoming information between nodes, so the nodes organize a graph of connections between them.
You can always check the node information in the TkeySpace app in the ⚙ Settings Contact and peer info App Status;

https://preview.redd.it/co1k25kqrtx41.png?width=619&format=png&auto=webp&s=e443a436b11d797b475b00a467cd9609cac66b83
TkeySpace creates initiating connections to servers registered in the blockchain Protocol as the main ones, from these servers it gets the addresses of nodes to which it can join, in turn, the nodes to which the connection occurred share information about other nodes.

https://i.redd.it/m21pw88srtx41.gif
TkeySpace sends network messages to nodes from supported blockchains in the app to get up-to-date data from the network.
The Protocol uses data structures for communication between nodes, such as block propagation over the network, so before network messages are read, nodes check the “magic number”, check the first bytes, and determine the type of data structure. In the blockchain, the “magic number” is the network ID used to filter messages and block traffic from other p2p networks.
Magic numbers are used in computer science, both for files and protocols. They identify the type of file/data structure. A program that receives such a file/data structure can check the magic number and immediately find out the intended type of this file/data structure.
The first message that your node sends is called a Version Message. In response, the node waits for a Verack message to establish a connection between other peers. The exchange of such messages is called a “handshake”.

https://preview.redd.it/b6gh0hitrtx41.png?width=785&format=png&auto=webp&s=0101eaec6469fb53818486fa13da110f6a4a851d
After the “handshake” is set, TkeySpace will start connecting to other nodes in the network to determine the last block at the end of the required blockchain. At this point — nodes request information about blocks they know using GetBlock messages — in response, your node receives an inv (Inventory Message) from another node with the information that it has the information that was requested by the TkeySpace node.
In response to the received message, inv — TkeySpace sends a GetData message containing a list of blocks starting immediately after the last known hash.

https://preview.redd.it/lare5lsurtx41.png?width=768&format=png&auto=webp&s=da8d27110f406f715292b439051ca221fab47f77

Loading and storing blocks

After exchanging messages, the block information is loaded and transactions are uploaded to your node. To avoid storing tons of information and optimize hard disk space and data processing speed, we use RDBMS — PostgreSQL in full nodes (local computer wallet).
In the TkeySpace mobile app, we use SQLite, and validation takes place by uploading block headers through the Merkle Tree, using the bloom filter — this allows you to optimize the storage of your mobile device as much as possible.
The block header includes its hash, the hash of the previous block, transaction hashes, and additional service information.
Block headers in the Tkeycoin network=84 bytes due to the extension of parameters to support nChains, which will soon be launched in “combat” mode. The titles of the Bitcoin block, Dash, Litecoin=80 bytes.

https://preview.redd.it/uvv3qz7wrtx41.png?width=1230&format=png&auto=webp&s=5cf0cd8b6d099268f3d941aac322af05e781193c
And so, let’s continue — application nodes receive information from the blockchain by uploading block headers, all data is synchronized using the Merkle Tree, or rather your node receives and validates information from the Merkle root.
The hash tree was developed in 1979 by Ralph Merkle and named in his honor. The structure of the system has received this name also because it resembles a tree.
The Merkle tree is a complete binary tree with leaf vertexes containing hashes from data blocks, and inner vertexes containing hashes from adding values in child vertexes. The root node of the tree contains a hash from the entire data set, meaning the hash tree is a unidirectional hash function. The Merkle tree is used for the efficient storage of transactions in the cryptocurrency blockchain. It allows you to get a “fingerprint” of all transactions in the block, as well as effectively verify transactions.

https://preview.redd.it/3hmbthpxrtx41.png?width=677&format=png&auto=webp&s=cca3d54c585747e0431c6c4de6eec7ff7e3b2f4d
Hash trees have an advantage over hash chains or hash functions. When using hash trees, it is much less expensive to prove that a certain block of data belongs to a set. Since different blocks are often independent data, such as transactions or parts of files, we are interested in being able to check only one block without recalculating the hashes for the other nodes in the tree.
https://i.redd.it/f7o3dh7zrtx41.gif
The Merkle Tree scheme allows you to check whether the hash value of a particular transaction is included in Merkle Root, without having all the other transactions in the block. So by having the transaction, block header, and Merkle Branch for that transaction requested from the full node, the digital wallet can make sure that the transaction was confirmed in a specific block.

https://i.redd.it/88sz13w0stx41.gif
The Merkle tree, which is used to prove that a transaction is included in a block, is also very well scaled. Because each new “layer” added to the tree doubles the total number of “leaves” it can represent. You don’t need a deep tree to compactly prove transaction inclusion, even among blocks with millions of transactions.

Statistical constants and nChains

To support the Tkeycoin cryptocurrency, the TkeySpace application uses additional statistical constants to prevent serialization of Merkle tree hashes, which provides an additional layer of security.
Also, for Tkeycoin, support for multi-chains (nChains) is already included in the TkeySpace app, which will allow you to use the app in the future with most of the features of the TKEY Protocol, including instant transactions.

The Bloom Filter

An additional level of privacy is provided by the bloom filter — which is a probabilistic data structure that allows you to check whether an element belongs to a set.

https://preview.redd.it/7ejkvi82stx41.png?width=374&format=png&auto=webp&s=ed75cd056949fc3a2bcf48b4d7ea78d3dc6d81f3
The bloom filter looks for whether a particular transaction is linked to Alice, not whether Alice has a specific cryptocurrency. In this way, transactions and received IDs are analyzed through a bloom filter. When “Alice wants to know about transaction X”, an ID is requested for transaction X, which is compared with the filled segments in her bloom filter. If “Yes” is received, the node can get the information and verify the transaction.

https://preview.redd.it/gjpsbss3stx41.png?width=1093&format=png&auto=webp&s=4cdcbc827849d13b7d6f0b7e7ba52e65ddc03a82

HD support

The multi-currency wallet TkeySpace is based on HD (or hierarchical determinism), a privacy-oriented method for generating and managing addresses. Each wallet address is generated from an xPub wallet (or extended public key). The app is completely anonymous — and individual address is generated for each transaction to accept a particular cryptocurrency. Even for low-level programming, using the same address is negative for the system, not to mention your privacy. We recommend that you always use a new address for transactions to ensure the necessary level of privacy and security.
The EXT_PUBLIC_KEY and EXT_SECRET_KEY values for DASH, Bitcoin, and Litecoin are completely identical. Tkeycoin uses its values, as well as other methods for storing transactions and blocks (RDBMS), and of course — nChains.

Secret key

Wallets in the blockchain have public and private keys.

Centralized applications usually store users’ private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
A private key is a special combination of characters that provides access to cryptocurrencies stored on the account. Only a person who knows the key can move and spend digital assets.
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. A backup keyword provides the maximum level of security.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If a 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 strict order, as it was presented after generation.

Result

Now we understand that your application TkeySpace is a node of the blockchain that communicates with other nodes using p2p messages, stores block headers and validate information using the Merkle Tree, verifies transactions, filters information using the bloom filter, and operates completely in a decentralized model. The application code contains all the necessary blockchain settings for communicating with the network, the so-called chain parameters.
TkeySpace is a new generation mobile app. A completely new level of security, easy user-friendly interfaces and all the necessary features that are required to work with cryptocurrency.

UNSUBSTANTIATED RUMOUR: I'm hearing reports from normally reliable contacts that there are serious problems with the bitcon.com mining operation, and hackers are involved. Bitcon.com customers getting pissed. They're not mining on BTC or BCH. Looks like it's all over.

LOL. Any comment Salty Roger? MemoryDealers ?
Last block mined on BTC: 583242 (2 days ago)
Last block mined on BCH: 589572 (22 hours ago)
Apparently Emil Oldenburg has gone missing after publicly arguing with Roger, and Shaun Chong has been fired and for now Hans Engren is trying to fix things - and until we see any Proof of Work (i.e. mined blocks) from Bitcon.com it is obvious he is failing, and the hackers are in charge.
This is not a ransom attempt apparently - this is a seek/destroy takedown. All their office computers are down too!
UPDATE
Japan is getting this news right now How long for China?
UPDATE #2 2019-07-03 11:55 UTC
I've been provided with some technical details and it all makes sense:-
Of course /npc is quiet about all of this because of fear, uncertainty, doubt.. no not FUD about this news, but FUD about being banned for speaking against them or questioning the truth or their narratives in the "uncensored subreddit"
UPDATE #3 2019-07-03 13:16 UTC
cash.coin.dance really does need to fix its pie chart code. bitcoin.com still appears there in "blocks mined today" piechart however it's been over 26 hours now since last block mined on BAB.
Please anon sending me messaging stating: "Roger is 51% attacking his own chain as Unknown Miner to double-spend the 3 million BAB he is moving". Don't spread FUD. We know due to centralisation and checkpointing that it's impossible to do this so easily. I have 2 sources who I communicate with daily who are giving me all this info. More news to come, but I want to wait for some sort of signal.
There is now a thread of discussion on /npc will be nice to see how they deny/ignore this one, however attempts have already been made and corrected. Remember BLOCKCHAIN = TRUTH.
UPDATE #4 2019-07-03 14:00 UTC
About those 3 million BAB that moved across the chain.... hmmmmm.... what if Roger moved it, but didn't move it to where he expected, now knows it didn't go where he thought he sent it, and has additional problem of not being able to rollback the blockchain due to "checkpoints" after 10 blocks as other miners are mining including "Unknown Miner" ;) Miner collusion impossible if "Unknown Miner" says "NO". Do we get another emergency ABC release?
C'mon Roger - time to speak out and inform especially those people who idolise you on /npc. Nobody will blame you, easy errors to make. Blame Emil - he hired guy who setup the VPN.
UPDATE #5 2019-07-03 14:18 UTC
Finally coin.dance have fixed their piechart code! Now it's easy for all to see... where is bitcoin.com ?
OK I have been told I'm going to receive documentary evidence about all that has happened around 17:00hs UTC. They've told me they'd rather Roger be straight with his followers in the meantime, but hey - we all know Roger!
UPDATE #6 2019-07-04 05:12 UTC
I fell asleep watching coin.dance waiting for BTC block, sorry folks. I thought my contacts were late due to "variance" in their rendezvous time but no. They told me "will update at 5" and I presumed 17:00. Nope, it's 05:00. They've told me to watch the blockchain for clues, they realise best way to catch out Roger is to produce a series of events, and watch his social media reaction. We've already seen the "everything is OK" narrative at /npc as a block (589720) magically appeared after 26 hours on the BAB chain. In fact things were so good that David Shares was forced to make "dupe post" about it. If David Shares had been a user making a dupe post about a "bad topic" he'd of been banned by David Shares. We've got evidence logs of him banning 3 people in past few weeks just for making duplicate posts on the "we don't censor" subreddit.
Let's examine the blockchain, cause according to /npc "everything is OK".
Number of BTC blocks mined by bitcoin.com since this post was made: 0
Number of BAB blocks mined by bitcoin.com since this post was made: 3 (some are calling these "virtue signalling blocks", and it's a lot cheaper to virtue signal with BAB).
Last BTC block mined is still 583242 (2019-07-01 01:01:38). That's 76 hours without block.
Last BCH blocks mined:-
10 hour gap.
589747
589736
589720
26 hour gap. This post was made.
589572
589520
589487
589479
589442
If you think 3 BAB blocks in 36 hours is OK then I have a SHA257 (that's 1 better than a 256 model) miner to sell you.
"jim-btc we will update within 24 hours. Watch the blockchain. We repeat watch the blockchain". Roger that my secret contacts, thanks!
UPDATE #7 2019-07-04 10:24
I've posted all the block times for both BTC & BAB so you can see this "variance" lie is not going to work for very long.
This is NOT financial advise
If you have BAB - dump that shit faster than a smelly diaper... it's obvious to all except those trapped in the BAB BABble bubble that something really stinks!

Looking back 18 months.

I was going through old emails today and came across this one I sent out to family on January 4, 2018. It was a reflection on the 2017 crypto bull market and where I saw it heading, as well as some general advice on crypto, investment, and being safe about how you handle yourself in cryptoland.
I feel that we are on the cusp of a new bull market right now, so I thought that I would put this out for at least a few people to see *before* the next bull run, not after. While the details have changed, I don't see a thing in this email that I fundamentally wouldn't say again, although I'd also probably insist that people get a Yubikey and use that for all 2FA where it is supported.
Happy reading, and sorry for some of the formatting weirdness -- I cleaned it up pretty well from the original email formatting, but I love lists and indents and Reddit has limitations... :-/
Also, don't laught at my token picks from January 2018! It was a long time ago and (luckliy) I took my own advice about moving a bunch into USD shortly after I sent this. I didn't hit the top, and I came back in too early in the summer of 2018, but I got lucky in many respects.
----------------------------------------------------------------------- Jan-4, 2018
Hey all!
I woke up this morning to ETH at a solid $1000 and decided to put some thoughts together on what I think crypto has done and what I think it will do. *******, if you could share this to your kids I’d appreciate it -- I don’t have e-mail addresses, and it’s a bit unwieldy for FB Messenger… Hopefully they’ll at least find it thought-provoking. If not, they can use it as further evidence that I’m a nutjob. 😉
Some history before I head into the future.
I first mined some BTC in 2011 or 2012 (Can’t remember exactly, but it was around the Christmas holidays when I started because I had time off from work to get it set up and running.) I kept it up through the start of summer in 2012, but stopped because it made my PC run hot and as it was no longer winter, ********** didn’t appreciate the sound of the fans blowing that hot air into the room any more. I’ve always said that the first BTC I mined was at $1, but looking back at it now, that’s not true – It was around $2. Here’s a link to BTC price history.
In the summer of 2013 I got a new PC and moved my programs and files over before scrapping the old one. I hadn’t touched my BTC mining folder for a year then, and I didn’t even think about salvaging those wallet files. They are now gone forever, including the 9-10BTC that were in them. While I can intellectually justify the loss, it was sloppy and underlines a key thing about cryptocurrency that I believe will limit its widespread adoption by the general public until it is addressed and solved: In cryptoland, you are your own bank, and if you lose your password or account number, there is no person or organization that can help you reset it so that you can get access back. Your money is gone forever.
On April 12, 2014 I bought my first BTC through Coinbase. BTC had spiked to $1000 and been in the news, at least in Japan. This made me remember my old wallet and freak out for a couple of months trying to find it and reclaim the coins. I then FOMO’d (Fear Of Missing Out”) and bought $100 worth of BTC. I was actually very lucky in my timing and bought at around $430. Even so, except for a brief 50% swing up almost immediately afterwards that made me check prices 5 times a day, BTC fell below my purchase price by the end of September and I didn’t get back to even until the end of 2015.
In May 2015 I bought my first ETH at around $1. I sent some guy on bitcointalk ~$100 worth of BTC and he sent me 100 ETH – all on trust because the amounts were small and this was a small group of people. BTC was down in the $250 range at that point, so I had lost 30-40% of my initial investment. This was of the $100 invested, so not that much in real terms, but huge in percentages. It also meant that I had to buy another $100 of BTC on Coinbase to send to this guy. A few months after I purchased my ETH, BTC had doubled and ETH had gone down to $0.50, halving the value of my ETH holdings. I was even on the first BTC purchase finally, but was now down 50% on the ETH I had bought.
The good news was that this made me start to look at things more seriously. Where I had skimmed white papers and gotten a superficial understanding of the technology before FOMO’ing, I started to act as an investor, not a speculator. Let me define how I see those two different types of activity:
So what has been my experience as an investor? After sitting out the rest of 2015 because I needed to understand the market better, I bought into ETH quite heavily, with my initial big purchases being in March-April of 2016. Those purchases were in the $11-$14 range. ETH, of course, dropped immediately to under $10, then came back and bounced around my purchase range for a while until December of 2016, when I purchased a lot more at around $8.
I also purchased my first ICO in August of 2016, HEAT. I bought 25ETH worth. Those tokens are now worth about half of their ICO price, so about 12.5ETH or $12500 instead of the $25000 they would be worth if I had just kept ETH. There are some other things with HEAT that mean I’ve done quite a bit better than those numbers would suggest, but the fact is that the single best thing I could have done is to hold ETH and not spend the effort/time/cost of working with HEAT. That holds true for about every top-25 token on the market when compared to ETH. It certainly holds true for the many, many tokens I tried to trade in Q1-Q2 of 2017. In almost every single case I would have done better and slept better had I just held ETH instead of trying to be smarter than Mr. Market.
But, I made money on all of them except one because the crypto market went up more in USD terms than any individual coin went down in ETH or BTC terms. This underlines something that I read somewhere and that I take to heart: A rising market makes everyone seem like a genius. A monkey throwing darts at a list of the top 100 cryptocurrencies last year would have doubled his money. Here’s a chart from September that shows 2017 year-to-date returns for the top 10 cryptocurrencies, and all of them went up a *lot* more between then and December. A monkey throwing darts at this list there would have quintupled his money.
When evaluating performance, then, you have to beat the monkey, and preferably you should try to beat a Wall Street monkey. I couldn’t, so I stopped trying around July 2017. My benchmark was the BLX, a DAA (Digital Asset Array – think fund like a Fidelity fund) created by ICONOMI. I wasn’t even close to beating the BLX returns, so I did several things.
  1. I went from holding about 25 different tokens to holding 10 now. More on that in a bit.
  2. I used those funds to buy ETH and BLX. ETH has done crazy-good since then and BLX has beaten BTC handily, although it hasn’t done as well as ETH.
  3. I used some of those funds to set up an arbitrage operation.
The arbitrage operation is why I kept the 11 tokens that I have now. All but a couple are used in an ETH/token pair for arbitrage, and each one of them except for one special case is part of BLX. Why did I do that? I did that because ICONOMI did a better job of picking long-term holds than I did, and in arbitrage the only speculative thing you must do is pick the pairs to trade. My pairs are (No particular order):
I also hold PLU, PLBT, and ART. These two are multi-year holds for me. I have not purchased BTC once since my initial $200, except for a few cases where BTC was the only way to go to/from an altcoin that didn’t trade against ETH yet. Right now I hold about the same 0.3BTC that I held after my first $100 purchase, so I don’t really count it.
Looking forward to this year, I am positioning myself as follows:
Looking at my notes, I have two other things that I wanted to work into this email that I didn’t get to, so here they are:
  1. Just like with free apps and other software, if you are getting something of value and you didn’t pay anything for it, you need to ask why this is. With apps, the phrase is “If you didn’t pay for the product, you are the product”, and this works for things such as pump groups, tips, and even technical analysis. Here’s how I see it.
    1. People don’t give tips on stocks or crypto that they don’t already own that stock or token. Why would they, since if they convince anyone to buy it, the price only goes up as a result, making it more expensive for them to buy in? Sure, you will have friends and family that may do this, but people in a crypto club, your local cryptocurrency meetup, or online are generally not your friends. They are there to make money, and if they can get you to help them make money, they will do it. Pump groups are the worst of these, and no matter how enticing it may look, stay as far away as possible from these scams. I even go so far as to report them when I see them advertise on FB or Twitter, because they are violating the terms of use.
    2. Technical analysis (TA) is something that has been argued about for longer than I’ve been alive, but I think that it falls into the same boat. In short, TA argues that there are patterns in trading that can be read and acted upon to signal when one must buy or sell. It has been used forever in the stock and foreign exchange markets, and people use it in crypto as well. Let’s break down these assumptions a bit.
i. First, if crypto were like the stock or forex markets we’d all be happy with 5-7% gains per year rather than easily seeing that in a day. For TA to work the same way in crypto as it does in stocks and foreign exchange, the signals would have to be *much* stronger and faster-reacting than they work in the traditional market, but people use them in exactly the same way.
ii. Another area where crypto is very different than the stock and forex markets centers around market efficiency theory. This theory says that markets are efficient and that the price reflects all the available information at any given time. This is why gold in New York is similar in price to gold in London or Shanghai, and why arbitrage margins are easily <0.1% in those markets compared to cryptoland where I can easily get 10x that. Crypto simply has too much speculation and not enough professional traders in it yet to operate as an efficient market. That fundamentally changes the way that the market behaves and should make any TA patterns from traditional markets irrelevant in crypto.
iii. There are services, both free and paid that claim to put out signals based on TA for when one should buy and sell. If you think for even a second that they are not front-running (Placing orders ahead of yours to profit.) you and the other people using the service, you’re naïve.
iv. Likewise, if you don’t think that there are people that have but together computerized systems to get ahead of people doing manual TA, you’re naïve. The guys that I have programming my arbitrage bots have offered to build me a TA bot and set up a service to sell signals once our position is taken. I said no, but I am sure that they will do it themselves or sell that to someone else. Basically they look at TA as a tip machine where when a certain pattern is seen, people act on that “tip”. They use software to see that “tip” faster and take a position on it so that when slower participants come in they either have to sell lower or buy higher than the TA bot did. Remember, if you are getting a tip for free, you’re the product. In TA I see a system when people are all acting on free preset “tips” and getting played by the more sophisticated market participants. Again, you have to beat that Wall Street monkey.
  1. If you still don’t agree that TA is bogus, think about it this way: If TA was real, Wall Street would have figured it out decades ago and we would have TA funds that would be beating the market. We don’t.
  2. If you still don’t agree that TA is bogus and that its real and well, proven, then you must think that all smart traders use them. Now follow that logic forward and think about what would happen if every smart trader pushing big money followed TA. The signals would only last for a split second and would then be overwhelmed by people acting on them, making them impossible to leverage. This is essentially what the efficient market theory postulates for all information, including TA.
OK, the one last item. Read this weekly newsletter – You can sign up at the bottom. It is free, so they’re selling something, right? 😉 From what I can tell, though, Evan is a straight-up guy who posts links and almost zero editorial comments.
Happy 2018.

100 Reasons to Buy Bitcoin

  1. Bitcoin is the most censorship resistant money in the world.
  2. You don't have to buy a “whole” bitcoin so don't freak out if you look at the price. You can buy a piece of one no problem.
  3. The Dallas Mavericks accept Bitcoin on their website. You don't trust Mark Cuban. He's the best shark.
  4. Bitcoin is the best performing asset of the last decade (better than S&P500).
  5. Diversify your current portfolio.
  6. It's not illegal in the USA.
  7. You holding just one satoshi slightly limits the supply and can rise the price for everyone else.
  8. [In late 2019] hash rate is the highest it has ever been
  9. Suicide insurance; if Bitcoin rises in price there is no worse feeling than regret.
  10. Some of the smartest people in computer science and cryptography are working on it. Trust nerds.
  11. Look at the all time historical chart. No technical analysis just tell me what you think when you look at it.
  12. Money is a belief system... and I want to believe.
  13. Transparent ledger, no funny business going on it's easy to audit.
  14. Elon Musk appears to be a fan. How's that for an appeal to authority
  15. There is a fixed limit in the number of bitcoins that will exist. 21 million bitcoin, 7 billion people on earth. Do the math.
  16. There are so many examples of governments inflating their currency to the point where it becomes unusable. Read the wikipedia page for Venezuela or Zimbabwe.
  17. Altcoins make sacrifices in either security or centralization. There are altcoins out there that claim to be innovating but just check the scoreboard nothing has flipped Bitcoin in market value or even gotten close.
  18. With technology developing at a rate faster than law, governments and for-profit businesses have the ability to monitor our purchases, location, our habits, and all of this has happened without consent. People made jokes and conspiracy theory, but sometimes conspiracy is real. Most people are good, but there is absolutely evil out there. There are absolutely evil people in positions of power. There are absolutely evil people that work together in positions of power. Does anyone actually believe that Jeffrey Epstein committed suicide. Go read about Leslie Wexner. Go read the cypherpunk manifesto.
  19. The upcoming halvening in 2020 will reduce the number of Bitcoin created in each block, making them more scarce, and if history repeats more valuable.
  20. Bitcoin has lower fees than traditional banking.
  21. Gold has the advantage of being a physical thing. But unlike gold you know Bitcoin is not forged, or mixed with another metal, and you can easily break it into tiny pieces and send it over the internet to someone.
  22. Bitcoin could spark new interests maybe you start to read more into economics, computer science, or Brock Pierce.
  23. Bitcoin has survived with no leader, marketing team, public relations, or legal team.
  24. Because Wired magazine said Bitcoin was dead at $2, Forbes said it was dead at $15, NY Times at $208, and CNN at $333.
  25. Just do a cost benefit analysis. What happens if Bitcoin fails and it goes to zero vs. what happens if it succeeds, and becomes world money.
  26. Bitcoin encourages long term thinking, planning, saving. Due to inflation we are punished by holding on to cash. Look up the statistics on the average savings account while we are bombarded with consumerist bullshit like Funko pop heads, Loot crate subscription services, and new syrup flavors for coffee. Currently we are encouraged to spend now, seek immediate gratification, and ignore what we are becoming as Amazon picks out our clothes and toothpaste ships it to the house and we sit and watch streaming services where content is pushed to us and I'm supposed to buy that this garbage is actually “trending”. Our lives have become so comfortable that idiots spend $60 to escape a room and have someone take your picture when you get out. What would our ancestors think.
  27. Maybe you're a day trader looking to use a trading bot in an unregulated market.
  28. Bitcoin has 7 letters in it. Lucky number 7.....
  29. Bitcoin promises to bank the unbanked, and provide services to those not otherwise “qualified” to open a bank account.
  30. It's just cool, don't you want to seem smart to all your friends.
  31. The origin story is so nuts there's going to be a movie or several movies about the early days of Bitcoin. Satoshi Nakamoto remains anonymous to this day. Imagine if the inventor of the cell phone was anonymous.
  32. If you have money to burn, don't buy soda, weed, or some girls private snapchat it's a dead end put it towards Bitcoin and give it to your child in the future.
  33. To avoid getting ripped off by foreign exchange fees just because you were born one place and your friends were born in another place.
  34. Can't live off the grid in your log cabin and still use Mastercard. Bitcoin is one piece of opting out.
  35. If one country adopts BTC as the national currency, it doesn't take much thought to realise that others will follow.
  36. Join a welcoming and unique community. Everyone is super nice because they want your money.
  37. You can stick it to the baby boomers.
  38. You can stick it to the vegans.
  39. You can stick it Roger Ver.
  40. Maybe your IQ is 70 and you'll do whatever CNBC Fast Money recommends.
  41. Maybe a hacker infects your computer, records you doing that thing, and threatens to release the tape if you do not pay them 1.5 Bitcoin.
  42. You're a risk taker looking for some risky investment.
  43. Aliens attack like Independence Day, blow up major cities in major countries, your money is still safe with Bitcoin. As long as there is a some guy, some person, living on an island with a copy of the ledger out there on your'e good. We're all good.
  44. Many proposals to scale the number of transactions, may the best plan win.
  45. One day you might have to use BTC to pay taxes, buy food, and charge your Tesla.
  46. You want to support a political group and remain private.
  47. You can trust math more than you can trust people to set an emission rate.
  48. Government don't know how much you have.
  49. The first response to Bitcoin being published by Hal Finney stated that Bitcoin was positioned to reach million dollar valuation. Hal was the first bull and passed away in 2014, missing a lot #doitforHal.
  50. Baddies can't freeze your money if they mad at you.
  51. The Big Bang Theory mentioned it, maybe you want to be like Sheldon the bazinga guy.
  52. Mid-life crisis.
  53. Be contrarian. In a world where everyone zigs it's sometimes good to zag.
  54. Don't have any hobbies, and you just need a reason to get up in the morning.
  55. Enjoy learning? Bitcoin is a topic where there is so much to learn, and so much development, that it really becomes a never ending journey. For someone who likes learning, it's more productive than speedrunning a video game.
  56. Yolo. You only live once. This isn't a dress rehearsal, if there's something your kind of interested in pursue it. That's true for anything not just Bitcoin. But if you're reading this I'm assuming you're interested.
  57. Bitcoin is not a ponzi scheme. The difference is Bitcoin does not need new people buying in to work, blocks being added will continue even if the community stopped growing.
  58. With religion on the decline maybe you want to join a cult. Crypto twitter is a great echo chamber to meet like minded people.
  59. Satoshi Nakamoto found a way to distribute a global currency in a fair way with the ability to adjust the mining difficulty as we go, it's really incredible. You still need computers and electricity to mine new bitcoin today but it's an extremely fair way for people to earn. There was no premine of Bitcoin. Everyone who has Bitcoin either bought it at what the market said, or they earned it.
  60. No CEO in charge of Bitcoin to make bad decisions or a board of directors that can make changes. The users, an ever growing number, are in charge.
  61. Bitcoin has no days off, it has no workers in charge who can get sick or take a holiday.
  62. Bitcoin has survived 10 years (and more). While there will always be dangers, I'd argue that those first few years it was most vulnerable to fail.
  63. Have some trust in the cypherpunks. Anyone who held and didn't sell bitcoin as it went from pennies to five figures is not looking to get rich. They want to change the world.
  64. Potential president Tulsi Gabbard disclosed owning some.
  65. Digital money is the future, anyone who has tried Venmo can see that. Well Bitcoin is a digitally native asset.
  66. Refugees can use Bitcoin to store their wealth as they flee a failing country.
  67. Bitcoin is an open source project. Anthony Pompliano likes to call it a virus but I like how the author of the Bitcoin Standard describes it. Bitcoin is like a song. As long as one person remembers it you can't destroy a song.
  68. Triple entry accounting. When humans first started recording who owes who what we had single-entry accounting. The king's little brother would keep everything written down, but we had to really trust this guy because he could simply erase a line and that money would be gone. When double-entry accounting started to spread 500 years ago it brought with it massive innovation. Businesses could now form relationships across the ocean as they each kept a record. We did not have innovation again until Satoshi's Bitcoin, where blockchain can be used as the neutral third party to keep record. It might not sound important but blockchain allows us to agree upon an objective reality.
  69. Bitcoin is non-political.
  70. Bitcoin is easy to accept. I mean kind of. It's certainly easier than setting up a bank account.
  71. A sandwich used to cost 10 cents in America, I walk into Subway and they don't even have $5 foot longs anymore. Inflation man..
  72. It's a peaceful protest.
  73. Critics say that mining wastes electricity, but if Bitcoin adoption continues the world will actually be incentivized to produce more renewable energy. There are so many waterfalls and sources of energy in the middle of nowhere right now. People might not see a reason to build a power plant over there now, but in the future it can make business sense. Take that waterfall mine bitcoin, and sell them to the people who can't mine. It allows for a business to sell their energy anywhere.
  74. Get into debates around Bitcoin, build those critical thinking skills.

Electroneum Blockchain Upgrade FAQ

FREQUENTLY ASKED QUESTIONS
ELECTRONEUM’S MODERATED BLOCKCHAIN
Q: What is a Moderated Blockchain?
A: Electroneum’s new Moderated Blockchain (a type of permissioned blockchain that is at the qualitative level of IBM’s Hyperledger or Facebook’s announced Libra open ledger network) that has been uniquely and cleverly developed to provide Electroneum with a minimal but sufficient level of interference. This will allow the highly skilled engineering staff to supervise the distributed ledger which is maintained by a list of trusted validators. And this allows the tech team to detect anomalies or irregularities that could come from hackers attempting to breach our security, and immediately stop them preventing a double-spend or 51% attack. Because Electroneum controls the list of trusted validators, this empowers them to guarantee, and that is similar to IBM’s hyper ledger or that of Facebook’s Libra blockchain.
Q: Why did you move to a Moderated Blockchain?
A: To improve the functionality of Electroneum at the exchanges, allowing them to confirm deposit transactions faster and to protect the network from 51% attacks, and also Electroneum can decide to where the block rewards are rerouted ensuring that they are used to help improve the lives of the poorer in underdeveloped countries.
Q: What is the role of blockchain in a permissioned network?
A: It is essentially an immutable history of financial transactions. Electroneum’s Moderated Blockchain, which is a type of permissioned blockchain, unlike other decentralised cryptocurrency networks, can guarantee a tamper-proof system of transactional records.
Q: What motivation would someone have to trade on a permissioned blockchain when their transaction could get rolled back, or worse still, never get confirmed?
A: With Electroneum’s new Moderated Blockchain reorganisations can still occur but never will an irregular transaction actually be fully confirmed and then overwritten.
Q: Is there any risk of manipulation with a moderated blockchain?
A: There is a risk of manipulation if an authenticator key is leaked. However, the extent would be negligible and therefore not affect users, exchanges or miners. We developed a system to closely monitor the behaviour of both the network and miners to ensure any foul play is immediately crushed.
Q: How is Electroneum’s Moderated Blockchain different to other decentralised blockchains?
A: We have the authority to decide who mines the blocks and therefore, we can increase the likelihood that they are trusted validators.
Q: Why doesn’t Electroneum move to a fully centralised blockchain?
A: Our unique and cleverly created Moderated Blockchain is meant to have minimal interference to remove the risks and add protection whilst remaining decentralised to the point wherein the unlikely event that a meteor was to wipe out all of the Electroneum staff out of the face of the Earth by a meteor, ETN would not cease to exist. This because those nodes currently mining our blockchain or anybody else for that fact could swap out the codes and fork the network to take over control and guarantee the permanence of the cryptocurrency thus shielding our users from losses.
Q: What is Proof of Responsibility or PoR?
A: Proof of Responsibility, or PoR for short, is a new mining paradigm which obligates the miners to two primary responsibilities which are: 1) Maintain the integrity of the payment network, and 2) Spend the block rewards they receive responsibly to help poor people in line with Electroneum’s humanitarian agenda.
Q: How does PoR compare to PoW or Proof of Work?
A: PoR saves a lot of time and energy compared to PoW because instead of working with block validators overtime to prove or not that they’re reliable miners, we save time and potential adverse issues by hand-picking the miners ourselves.
SECURITY AND 51% ATTACKS OR DOUBLE SPENDS
Q: What is a 51% attack?
A: It is when someone takes over 50% control of the hashing power of a cryptocurrency. Hackers usually use this to benefit themselves with double spends, which is a hard loss for the exchanges as well as users in many cases.
Q: What IS an example of a 51% attack?
A: You may know 51% attacks better from both Bitcoin Cash in 2018 and Ethereum Classic in 2019, where hackers acquired more than 50 percent of the hashing power on those networks and getting away with a significant loot.
Q: What is hashing power?
A: This is the rate with which the mining rigs solve mathematical problems.
Q: Why doesn’t Electroneum require large amounts of hashing power anymore?
A: The Electroneum network difficulty automatically adjusts to maintain the target block time of two minutes. Regardless of the magnitude of the hashing power in Electroneum’s network will be kept to a two-minute target block time.
Q: Is Electroneum now insusceptible to a 51% attack?
A: We’re no longer susceptible to a 51% attack – making us one of the most secure blockchains in existence today.
Q: What if someone hack one authenticated miner?
A: In the unlikely event that hackers were to succeed in breaching the security of an authenticated miner, the authentication key of that miner would not be accessible to the hacker in itself because of the unique way our blockchain team has come up to shield it from being discovered. The hacker, therefore, would not be able to affect the network because they would be unable to mine sequential blocks. And because of the uniqueness of the Moderated Blockchain, our moderating network layer would immediately detect the breach and rescind the rights of that miner.
Q: What if two or more hacks?
A: If one hack is highly unlikely due to two security breaches being necessary, two hacks are exponentially harder to achieve. But if it were to happen, the keys they may have stolen limit the hash rate of the miner. This means that if somebody were to take the code and run it on the highest-powered mining machine, it would still produce the same hash rate as it would in the lowest powered mining rig making it impossible for them to control over 50% of the network’s hash rate because of the way our Moderated Blockchain is set up. This also ensures the NGOs can run an Electroneum mining node on hardware with which their tech teams are familiar.
Q: How do you judge how responsible the miners are?
A: We look at how many blocks they are mining compared to how many blocks they are expected to mine going by the hashing power allotted to them.
Q: What happens after a mining node has been shut off?
A: Simply, it stops mining and needs to be restarted and then retype or re-enter the authentication key.
NEW TRUSTED MINERS
Q: Who are the miners?
A: We have chosen vocational NGOs as trusted mining partners who are also trustworthy organisations. We have done due diligence to ensure they are transparent, honest, and aligned with our vision to work within the developing world. We have made sure that they also want to accompany us in our goal to expand our Gig Fair project, which is aimed at helping provide people in the poorest regions of the world with an income opportunity and the opportunity to attain skills and means to generate an income that will empower them to live better. The NGOs that we’ve selected are trusted brands that have proven track records in helping people. Cryptocurrency is at its early stages and is met with skepticism by many people and entities around the world as well as in the developing world. So, our mission is to educate these NGOs about cryptocurrency so that they can, in turn, convey the message of the benefits of crypto, particularly ETN, to people in the developing world and make them feel more confident to use crypto, which ultimately will help spur crypto’s mass adoption.
Q: Why are these NGOs anonymous (initially)?
A: Because they themselves have decided to remain anonymous over concerns of how cryptocurrency could reflect on their organisations.
Q: What do NGOs do for the project?
A: They validate the blocks and rewarded for this and take the proceeds to help people?
Q: Where are the NGO’s and Charities located?
A: For now, locations of the NGOs are being kept undisclosed for security reasons until they themselves decide they if they want to make public that information.
Q: Five million ETN or about $22,500 at the then valuation was paid out daily before. How much is being paid out now?
A: Because the block rewards have been reduced by a whopping 75% creating scarcity which is a good thing to extend longevity, currently just over 1.2 million ETN or about $5,300 is being paid out in block rewards.
Q: Can we see who is mining and how much they are mining?
A: The block rewards will still be visible on the blockchain explorer and those with sufficient technical knowledge will be able to see the different miners signing blocks with different mining keys. But Electroneum is not forcing the NGOs to reveal their identities because they are still going through a learning curve and when they understand crypto and experience the benefits first-hand, they will more than likely reveal themselves.
Q: Where are their mining rigs stored?
A: We have suggested that mining rigs be run in the cloud to ensure uptime; however, ultimately, it is up to the NGOs themselves decide where their equipment is hosted. It is essential to point out that we have reduced energy and hash rates by a millionfold as such a standard rack-mounted server that you would find in any business today is sufficient to run an Electroneum mining node.
Q: Who setup their mining rigs?
A: At this stage, all mining rigs have been set up by the Electroneum team as this is the first foray for NGOs into the cryptocurrency mining space.
Q: Who is managing their mining rigs?
A: The mining rigs are self-sufficient and need very little if any, technical support, however, a moderator layer monitors the new Moderated Blockchain to ensure the mining rigs are online and benefit the network. If we were to detect a mining rig going offline, we would inform the NGO and provide assistance where required.
Q: How will NGOs use their ETN (from mining blocks)?
A: The NGOs, initially, almost certainly convert the ETN to USD or other currencies because they have always used fiat to deliver their donations and assistance because that is what they are used to doing. Once they see the benefits and value of ETN they may start using it on the ground to amongst the people they help. We have deliberately targeted NGOs that are in regions that were we are imminent to enable airtime top-ups directly with ETN from within the Electroneum mobile app.
FUTURE PROGRESS & CORPORATE PARTNERSHIPS
Q: How will this initiative affect corporate partnerships moving forward?
A: Because the network is more secure, Electroneum as a platform will be more attractive as a platform in the eyes of potential partners.
Q: How will it help to grow our on-the-ground initiatives?
A: The NGO’s we’re working with will be in the regions we’re targeting on the ground. So, this will be contributing to the eco-system, the NGO’s will be able to spend their ETN on education through the Gig Economy too.
Q: Can new NGOs apply to mine?
A: I If you know or are an NGO that focuses on vocational training and education, and that it is within the developing world, then we would love to hear from you via our community forum.
Q: How will the 75% reduction in the block reward benefit the community?
A: Reducing the block rewards means ETN ‘s expands the longevity of the coin by making ETN scarcer and thus lengthening the duration of the emission of coins.

Decred Journal — June 2018

Note: You can read this on GitHub, Medium or old Reddit to see the 207 links.

Development

The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response.
dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage.
Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun.
Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal.
Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue.
dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues.
Ticket splitting: 11-way ticket split from last month has voted (transaction).
Ethereum support in atomicswap is progressing and welcomes more eyeballs.
decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page.
decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here.
Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)

Network

Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s.
F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%.
Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak).
Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1.
Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).

ASICs

Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target.
Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.comtranslated, also on asicminervalue)
dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.

Integrations

bepool.org is a new mining pool spotted on dcred.eu.
Exchange integrations:
Two OTC trading desks are now shown on decred.org exchanges page.
BitPro payment gateway added Decred and posted on Reddit. Notably, it is fully functional without javascript or cookies and does not ask for name or email, among other features.
Guarda Wallet integrated Decred. Currently only in their web wallet, but more may come in future. Notable feature is "DCR purchase with a bank card". See more details in their post or ask their representative on Reddit. Important: do your best to understand the security model before using any wallet software.

Adoption

Merchants:
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project).
The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below.
Arbitrade is now mining Decred.

Media

stakey.club: a new website by @mm:
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
@morphymore translated Placeholder's Decred Investment Thesis and Richard Red's write-up on Politeia to Chinese, while @DZ translated Decred Roadmap 2018 to Italian and Russian, and A New Kind of DEX to Italian and Russian.
Second iteration of Chinese ratings released. Compared to the first issue, Decred dropped from 26 to 29 while Bitcoin fell from 13 to 17. We (the authors) restrain ourselves commenting on this one.

Community Discussions

Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository.
An update on our communication systems:
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS.
A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people.
A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred.
"Against community governance" article was discussed on Reddit and #governance.
"The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here.
Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms.
Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.

Markets

DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market.
In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.

Relevant External

Obelisk announced Launchpad service. The idea is to work with coin developers to design a custom, ASIC-friendly PoW algorithm together with a first batch of ASICs and distribute them among the community.
Equihash-based ZenCash was hit by a double spend attack that led to a loss of $450,000 by the exchange which was targeted.
Almost one year after collecting funds, Tezos announced a surprise identification procedure to claim tokens (non-javascript version).
A hacker broke into Syscoin's GitHub account and implanted malware stealing passwords and private keys into Windows binaries. This is a painful reminder for everybody to verify binaries after download.
Circle announced new asset listing framework for Poloniex. Relevant to recent discussions of exchange listing bribery:
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss.
Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance".
Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case.
Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too? (slack)

About This Issue

This is the third issue of Decred Journal after April and May.
Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research.
The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue.
As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations.
Credits (Slack names, alphabetical order): bee and Richard-Red. Special thanks to @Haon for bringing May 2018 issue to medium.

Dev activity stats for May: 238 active PRs, 195 master commits, 32,831 added and 22,280 deleted lines spread across 8 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: rapid growth from ~4,000 TH/s at the beginning of the month to ~15,000 at the end with new all time high of 17,949. Interesting dynamic in hashrate distribution across mining pools: coinmine.pl share went down from 55% to 25% while F2Pool up from 2% to 44%. [Note: as of June 6, the hashrate continues to rise and has already passed 22,000 TH/s]
Staking: 30-day average ticket price is 91.3 DCR (+0.8), stake participation is 46.9% (+0.8%) with 3.68 million DCR locked (+0.15). Min price was 85.56. On May 11 ticket price surged to 96.99, staying elevated for longer than usual after such a pump. Locked DCR peaked at 47.17%. jet_user on reddit suggested that the DCR for these tickets likely came from a miner with significant hashrate.
Nodes: there are 226 public listening and 405 normal nodes per dcred.eu. Version distribution: 45% on v1.2.0 (up from 24% last month), 39% on v1.1.2, 15% on v1.1.0 and 1% running outdaded versions.

ASICs

Obelisk team posted an update. Current hashrate estimate of DCR1 is 1200 GH/s at 500 W and may still change. The chips came back at 40% the speed of the simulated results, it is still unknown why. Batch 1 units may get delayed 1-2 weeks past June 30. See discussions on decred and on siacoin.
@SiaBillionaire estimated that 7940 DCR1 units were sold in Batches 1-5, while Lynmar13 shared his projections of DCR1 profitability (reddit).
A new Chinese miner for pre-order was noticed by our Telegram group. Woodpecker WB2 specs 1.5 TH/s at 1200 W, costs 15,000 CNY (~2,340 USD) and the initial 150 units are expected to ship on Aug 15. (pow8.comtranslated)
Another new miner is iBelink DSM6T: 6 TH/s at 2100 W costing $6,300 (ibelink.co). Shipping starts from June 5. Some concerns and links were posted in these two threads.

Integrations

A new mining pool is available now: altpool.net. It uses PPLNS model and takes 1% fee.
Another infrastructure addition is tokensmart.io, a newly audited stake pool with 0.8% fee. There are a total of 14 stake pools now.
Exchange integrations:
OpenBazaar released an update that allows one to trade cryptocurrencies, including DCR.
@i2Rav from i2trading is now offering two sided OTC market liquidity on DCUSD in #trading channel.
Paytomat, payments solution for point of sale and e-commerce, integrated Decred. (missed in April issue)

Community Discussions

Community stats: Twitter 39,118 (+742), Reddit 8,167 (+277), Slack 5,658 (+160). Difference is between May 5 and May 31.
Reddit highlights: transparent up/down voting on Politeia, combining LN and atomic swaps, minimum viable superorganism, the controversial debate on Decred contractor model (people wondered about true motives behind the thread), tx size and fees discussion, hard moderation case, impact of ASICs on price, another "Why Decred?" thread with another excellent pitch by solar, fee analysis showing how ticket price algorithm change was controversial with ~100x cut in miner profits, impact of ticket splitting on ticket price, recommendations on promoting Decred, security against double spends and custom voting policies.
@R3VoLuT1OneR posted a preview of a proposal from his company for Decred to offer scholarships for students.
dcrtrader gained a couple of new moderators, weekly automatic threads were reconfigured to monthly and empty threads were removed. Currently most trading talk happens on #trading and some leaks to decred. A separate trading sub offers some advantages: unlimited trading talk, broad range of allowed topics, free speech and transparent moderation, in addition to standard reddit threaded discussion, permanent history and search.
Forum: potential social attacks on Decred.
Slack: the #governance channel created last month has seen many intelligent conversations on topics including: finite attention of decision makers, why stakeholders can make good decisions (opposed to a common narrative than only developers are capable of making good decisions), proposal funding and contractor pre-qualification, Cardano and Dash treasuries, quadratic voting, equality of outcome vs equality of opportunity, and much more.
One particularly important issue being discussed is the growing number of posts arguing that on-chain governance and coin voting is bad. Just a few examples from Twitter: Decred is solving an imagined problem (decent response by @jm_buirski), we convince ourselves that we need governance and ticket price algo vote was not controversial, on-chain governance hurts node operators and it is too early for it, it robs node operators of their role, crypto risks being captured by the wealthy, it is a huge threat to the whole public blockchain space, coin holders should not own the blockchain.
Some responses were posted here and here on Twitter, as well as this article by Noah Pierau.

Markets

The month of May has seen Decred earn some much deserved attention in the markets. DCR started the month around 0.009 BTC and finished around 0.0125 with interim high of 0.0165 on Bittrex. In USD terms it started around $81 and finished around $92, temporarily rising to $118. During a period in which most altcoins suffered, Decred has performed well; rising from rank #45 to #30 on Coinmarketcap.
The addition of a much awaited KRW pair on Upbit saw the price briefly double on some exchanges. This pair opens up direct DCR to fiat trading in one of the largest cryptocurrency markets in the world.
An update from @i2Rav:
We have begun trading DCR in large volume daily. The interest around DCR has really started to grow in terms of OTC quote requests. More and more customers are asking about trading it.
Like in previous month, Decred scores high by "% down from ATH" indicator being #2 on onchainfx as of June 6.

Relevant External

David Vorick (@taek) published lots of insights into the world of ASIC manufacturing (reddit). Bitmain replied.
Bitmain released an ASIC for Equihash (archived), an algorithm thought to be somewhat ASIC-resistant 2 years ago.
Three pure PoW coins were attacked this month, one attempting to be ASIC resistant. This shows the importance of Decred's PoS layer that exerts control over miners and allows Decred to welcome ASIC miners for more PoW security without sacrificing sovereignty to them.
Upbit was raided over suspected fraud and put under investigation. Following news reported no illicit activity was found and suggested and raid was premature and damaged trust in local exchanges.
Circle, the new owner of Poloniex, announced a USD-backed stablecoin and Bitmain partnership. The plan is to make USDC available as a primary market on Poloniex. More details in the FAQ.
Poloniex announced lower trading fees.
Bittrex plans to offer USD trading pairs.
@sumiflow made good progress on correcting Decred market cap on several sites:
speaking of market cap, I got it corrected on coingecko, cryptocompare, and worldcoinindex onchainfx, livecoinwatch, and cryptoindex.co said they would update it about a month ago but haven't yet I messaged coinlib.io today but haven't got a response yet coinmarketcap refused to correct it until they can verify certain funds have moved from dev wallets which is most likely forever unknowable (slack)

According to the company, the double-spend feature can be triggered if a hacker gains access into a user’s wallet, thereby making it unusable to the owner. Talking about how the exploit works, the developers at the Tel Aviv based company noted that the hackers exploit a crucial flaw in bitcoin’s replace by fee function. The developers of ZenGo crypto wallet discovered critical vulnerability for the attack of double spending called "BigSpender".. According to an official announcement, the vulnerability affected Ledger Live, Bread and Edge wallets.. The bug allows attackers to spend the same coins two or more times. The numbers I've seen quoted for a double spend attach on Bitcoin Cash (assuming guaranteed block space) are that it would cost about 50K to double spend on a 0-conf transaction. So really, you can confidently accept 0-conf for <1K reasonably. More that that you can accept 1-conf or more which can take a minute or two.
