Augur V2 is the next big step in Defi

This 6 month old Augur V2 video got me excited. I thought I’d share its value proposition, which I feel is currently being overlooked.
If you’ve been in the space for some time, you know what Augur is: a decentralized prediction market and the biggest (in ETH)/earliest ICO on Ethereum. Prediction markets allow for better forecasting by leveraging the power of incentivized wisdom of the crowd. V2 will soon launch with a revamped UI, cheap 0x orders and stablecoin integration. It’s set to become the most accessible, fair and open betting platform out there.
What you may not realize is its impact in the Defi space. Each market/prediction/question is represented by a token that can be traded in other Defi apps. This gives it incredible flexibility. Consider these possibilities:
This synergetic composability gets incredibly interesting when combined with other Defi legos. How about token sets based on bets between the ratios of active addresses on Ethereum vs Bitcoin? Why not make a Uniswap pair between a Real-T token and a bet against Detroit real-estate to hedge your position and gain transaction fees on the side?
Tokenomics
With growing interest over new Defi tokens, REP will no doubt position itself among the top. It’s one of the few that actually benefits from using a blockchain and has a utility that isn’t just governance related. Staked REP consensus is used to validate markets and collect fees in the process.
We’ve seen most successful Defi tokens pick up steam, especially in the past month, as mirrored by their sharp price increases: BNT +200%, KNC +90%, LEND + 70%, MKR +60%, LRC +140%. Augur V1 markets aren’t being used right now since the long awaited V2 is just around the corner. The repeated additional delays in V2’s launch date have kept its price comparatively low.
With that in mind, if one believes in the team’s ability to deliver and for Defi to continue growing, REP seems to be an extremely strong long term play. Whether you're a token holder or not, you'll likely see its contribution in many spheres of the Defi world. The above examples only scratch the surface of what it enables.

Spreading Crypto: How Protocols Reach Mainstream Adoption

Spreading Crypto: How Protocols Reach Mainstream Adoption
This is the first post of our Spreading Crypto series where we take a deep dive into what it’ll take to help this technology reach broader adoption. We look at some of the obstacles holding it back and what strategies we think will be successful.
Mick Hagen (FoundeCEO) talking about protocols and how they become adopted
Like many others working in crypto, I really want to see this tech reach a larger audience. I’ve been drinking crypto kool-aid for awhile now. I bought my first Bitcoin in 2013 and have been working full-time with decentralized protocols since 2014. I’ve been through the peaks of the bull market down to the depths of the bear market. Multiple times. I would not be all-in on this technology if I wasn’t a true believer.
I obviously hope that Genesis Block will play an important role. But this goes beyond self-interest. I think for most of us in the industry, increasing crypto adoption is not about money.
It’s not about dumping our bags on retail. But rather it’s about the positive impact we believe this technology can have on the lives and societies all around us.
So, how do we bring this to the masses? How do we rid ourselves of the reputational damage that came with Mt Gox and dark markets like Silk Road? How do we make this technology easier for the normals to use? Today we start answering those questions.
---

Protocols 101

Most of the products and services that we all enjoy today use protocols that are under the hood, operating in the background. For example, when you send someone an email you’re using a protocol called SMTP. When you browse the web, you’re using the HTTP protocol.
Protocols allow for applications, computers, and devices to interact with each other. They are similar to a spoken language, where they have their own set of rules and vocabulary. If two people share the same language, they can communicate with each other.
Protocols are usually hard for the common person to understand because they’re very technical and provide no user interface. There are a few rare cases where the protocols themselves have made it into the cultural lingo, like Bluetooth, WiFi, and SMS. But for the most part, protocols are invisible and hidden from end-users.
Other protocols that have reached broad adoption

Protocol Adoption

The world did not embrace the web when the TCP/IP or HTTP protocols were first invented. Nor did they start using email when the POP, SMTP, or IMAP protocols were invented. The masses started browsing the web when AOL and Netscape were launched. They started using email when Hotmail and Gmail went live.
Protocols become adopted when an application makes them more accessible and easier to use.
Protocols become adopted when a strong team abstracts away the complexity, and delivers a compelling product experience that solves a real user pain. This is a pattern that has repeated throughout the history of technology.
Other examples include XMPP (chat), VoIP (internet audio calls), WebRTC (video conferencing), and NFC (close-contact device communication). Those protocols weren’t widely adopted until the launch of applications like AIM, WhatsApp, Skype, Google Hangouts, and Apple Pay.
Protocols become adopted when the killer application arrives.
Screenshots of Netscape and Hotmail

Crypto Protocols

If history is any indication, crypto and blockchain will be no different. Bitcoin is a protocol. Ethereum is a protocol. Decentralized Finance (DeFi) is filled with low-level protocols. What many out there don’t realize — and those within our industry don’t like to acknowledge — is that Crypto today is mostly all protocols.
Decentralized protocols won’t be replacing Robinhood, SoFi, or Venmo anytime soon. They never will. They aren’t meant to!
Crypto protocols are the building blocks, the lego pieces, the primitives that developers can use to build applications on top of.
As with the numerous protocols that came before, these innovative protocols need world-class applications. They need product experiences that can propel this exciting tech to the masses. Crypto needs great product teams that abstract away all the blockchain complexity, and deliver it in a way that is simple, convenient, and powerful.
Decentralized protocols are like lego pieces

Crypto Industry

Protocols usually operate in the background. So it should be no surprise that interacting directly with crypto and decentralized protocols is raw, rough, confusing, and complicated for most “normal” people out there.
Most of the crypto industry today is still focused on protocol development. That’s totally fine — we’re still at the early stages of this entire industry.
But because of that protocol focus, it should be no surprise to any of us that we still haven’t seen mainstream adoption.
But as an industry, we cannot forget or lose sight of what it takes to reach the masses. As Mark Twain said, “history doesn’t repeat itself, but it often rhymes.”
If we want these exciting protocols to be adopted by billions of people around the world, we’re gonna need killer applications. Just like every protocol before.
In our next post, we’ll explore the current state of application development within crypto. Are we getting closer to that killer app? What will it look like? How do we achieve it? Stay tuned, that’s all coming next.

ARK. Here's what's it's all about, what's been going on, and what's coming. [Explain Like I'm Busy]

Dude, it said explain like I'm busy I'm not going to read all this

No problem. Check out these hand-picked relevant ARK Crypto Podcast episodes. Learn while you listen, drive to work or home, cook a steak, give your dog a bath, etc.
If you have decided to read all this, thanks, keep reading for a concise breakdown!

So what's the current big thing going on with ARK right NOW?

ARK.io has recently announced on both its blog and its Twitter that ARK Core v2.6 is coming to Mainnet February 11th. The iteration of 2.6 may sound anticlimactic, but it's far from that. Core v2.6 is the biggest upgrade to date- even bigger than the total Core overhaul performed for v2.0, deployed late 2018.
The new version brings new transaction types to the ARK Public Network, including types that will play a role in creating an ecosystem of linked chains. This ecosystem of linked chains will have the ARK Public Network in the center of the action, storing chain details and allowing for chain discovery.
These new transaction types include:
Multipayments — sending to multiple ARK addresses, while just initiating one transaction, saves time and cost
Multisignatures — you can now get all of the benefits of multisignatures where more than one user can propose or spend funds depending on the predefined terms (eg. 2 out of 3 users needed to successfully send tokens, vote, …)
IPFS — register IPFS compliant hashes on the ARK blockchain within Desktop Wallet.
Business & Bridgechain registrations — you can now register your business and bridgechain on the blockchain and soon, you will be able to get verified via our Marketplace to get access to some exciting new features.
Delegate resignation — delegates who don’t want to be voted for anymore can now opt-out of this by simply initiating delegate resignation.
Additionally, the Core v2.6 improves security against double-spend attacks by implementing nonces. Also, massive enhancements were made to the GTI or Generic Transaction Interface, a critical tool for developers who wish to develop decentralized applications.

What is ARK's unique approach to current issues plaguing the blockchain industry?

ARK empowers everyone, regardless of their aim or technical background, to quickly and easily leverage blockchain technology. In the current hype-driven blockchain landscape, ARK acts as a beacon for individuals, groups, and enterprises seeking to apply blockchain technology to both reach their individual goals and affect change in their local community. ARK’s uniquely simple technology stack allows almost anyone to create and deploy standalone blockchains for any use case with an intuitive graphical user interface and experience. These newly created blockchains also known as bridgechains will have the ability to interoperate through ARK SmartBridge Technology. ARK is also reinventing smart contracts with ARK Logic, a collection of tools including custom transaction types, templates, and plugins. ARK Logic brings security, adaptability, and scalability to decentralized computing workflows. Most importantly, the ARK Ecosystem fosters a growing international community of developers, node operators, blockchains, businesses, and enthusiasts who collectively breathe life into this disruptive technology. Get into the interactive whitepaper here.

Tell me about the ARK Public Network

Ok, no problem. Since coming online on March 21, 2017, the APN has operated as a P2P cryptocurrency with fast block times of 8 seconds and low dynamic fees (near a penny and somewhat novel for a DPoS blockchain). However, the end goal of the APN far exceeds that of just a cryptocurrency that is faster and cheaper to use than Bitcoin. I'll explain further in a minute.
The network, as mentioned, is set up as Delegated Proof-of-Stake. This means forging delegates are deemed worthy to secure the chain and add blocks to it by the holders of the ARK token, which vote for delegates using their ARK as vote weight. ARK remains in users' control at all times, and the top 51 delegates in vote weight enter forging status. The network awards each delegate 2 ARK per block (~12,705 ARK/mo) for services rendered. This continues ad infinitum resulting in a declining inflation rate each year (relative to total supply). When users add or remove ARK from a voting wallet address, vote weight adjusts automatically and they don't need to vote again. Voting continues even if user's wallet is offline.
The main uses of ARK as the cryptoasset of the ARK Public Network besides being a P2P cryptocurrency include:
If you're interested in more details about APN uses, check this direct link to that section of whitepaper.

Is team good?

Yes, team good. Team very good. General sentiment among ARK team members is that ARK is a dream project to work on, and this motivates them to do great work on a consistent basis as the ARK technology stack progresses. Very recently, ARK hired an additional half dozen people in various departments, including marketing department. This brings ARK team total to over three dozen experts. The ARK business entity is also well funded with around 10 years of budget. The ARK business entity spends funds in a very sensible manner compared to some other projects who spend with insufficient foresight or discretion.
Members of the board are thoughtful and deliberate, and the CEO FX Thoorens has been hard at work putting a spotlight on ARK, showing an 'intermeshing' of ARK with the global regulatory landscape in regards to crypto. Recently, ARK became a founding member of ADAN, a professional association based in France created to help structure and develop the digital assets industry. Other members include Consensys France and Ledger. ADAN will consult with public authorities, industry leaders and private bodies to promote the use of digital assets and all activities in this sector. This includes exchange platforms, brokers, hardware, protocols, decentralized applications and blockchain technology platforms. Hear FX Thoorens talk more about this in this podcast episode.
The ARK business entity is located in France, but the ARK team is distributed across 10+ countries and multiple continents.

What's going to happen?

Cool stuff. Organizations and open source projects have been stumbling across ARK and really like what they see. Multiple projects are working with ARK technology and are at various stages of development, but since you're busy, I'll highlight the project nOS which recently launched their public testnet and uses ARK technology for their blockchain. nOS also has great things to say about ARK that you can hear in this podcast episode or watch in this video.
We believe that as more businesses, organizations, and open source projects start looking around for blockchain solutions, they will also enjoy ARK's simplicity, flexibility, and feature set. Our powerful technology stack is backed up by a recently upgraded documentation hub for developers.
The product we have that makes it very easy for projects to join the ARK Ecosystem is called the ARK Deployer, which you can learn about in this two minute video. It allows developers from all walks of life to create, customize and launch a standalone blockchain in three simple steps. In the near future, what's going to happen is a big improvement to the Deployer. The ARK Deployer will get an upgraded and more powerful user interface that also facilitates chain management post-launch, as well as interface directly with cloud providers like Digital Ocean to launch genesis node and peers in background. This would allow for a massive leap forward in our vision of 'Point. Click. Blockchain.'
ARK.io is also working on a Marketplace for developers, where custom plugins and tools developed by both ARK.io as well as third parties can be acquired for assembling blockchains much easier. Imagine a wordpress-type environment where you can create a super-powerful and customized blockchain by connecting Legos together. In the same way that early World Wide Web needed WordPress/Squarespace style tools to bring the technology to every business or organization, we believe that this need will be out there for blockchain technology as this new decade progresses.
There is more cool stuff that is going to happen, but I'll wrap it up there for now.

After reading all this stuff, what is it you want me to do?

Well, not make any financial decisions, because that is not the purpose of this information. However, as a developer, there's a lot of interesting things you should know and may want to consider doing. The ARK technology stack uses TypeScript and other JS-style frameworks, so if you know those, you should get excited.
Here's some additional less 'developery' stuff you can do:
Thanks for coming along for the ride of this post. ARK has been out here, it's out here, and it's going to continue to be out here, doing its part to make sure everybody knows that blockchains are, in fact, a thing.

On ARPA’s 2nd Anniversary — A Letter from CEO

On ARPA’s 2nd Anniversary — A Letter from CEO

https://preview.redd.it/qg09bb6wony41.png?width=1400&format=png&auto=webp&s=bb461620b46a5233fbc5fdf67fa3d05806acb2e4
Dear friends and partners,
Time flies, and ARPA is turning two years old this week. It is a good time to sum up and look ahead.
First of all, I would like to thank you on behalf of the whole team for your continuing company and support. You are the reason that ARPA is always maturing and improving.
https://youtu.be/y7Xgd76xurw
I often joked that ARPA is a two-year-old baby in a three-year-old industry. Looking back on the history of the Internet and mobile Internet, blockchain practitioners are trailblazers in this long journey. Over the past two years, the ARPA team has thrived in both the blockchain industry and privacy-preserving computation. We’ve been through the crypto winter of 2018 and have witnessed the infancy phase of the blockchain and crypto industry.
At the crossroads of history, what choices should we make, and which direction will these choices lead? Please allow me to lead you through the past and the future of ARPA.
First, ARPA is becoming more adaptive than ever. The crypto industry has a typical dumbbell-shaped structure. It attracts the most talented developers in the world, and at the same time attracts individuals that of speculative nature. If we take Ethereum as an example, it has a large and loose group of developers. It is a global-scale social experiment to stimulate innovation with a ‘bazaar’ development model. We are a proud ecosystem buidler on Ethereum from the very beginning.
On the one hand, the world of blockchain and crypto is the continuation of the free software movement, cryptopunk culture, and is the ultimate demonstration of large-scale open-source collaboration. On the other hand, the speculative nature of cryptocurrencies has attracted a large number of new users who have little idea of how the technology works in detail, leading to chaos in the industry. Even regulators and traditional enterprises become cautious when talking about cryptocurrency.
With the research on digital currencies deepens in various countries, China is on the edge of launching DC/EP, Facebook has proposed and is implementing Libra, the entire crypto industry is entering the fast track, and mass adoption is right around the corner. The flexibility to change in the industry and the ability to make long-term beneficial choices are the prerequisites for ARPA surviving the many cycles ahead.
Second, the blockchain and privacy-preserving computation industries are on a steady rise. From the users’ perspective, Chinese DC/EP and Facebook’s Libra will bring digital currency to millions of households, and cryptocurrencies such as Bitcoin will also gain more users. The relationship between Bitcoin and sovereign digital currency is like Zion and Matrix in the Matrix. Sovereign digital currency is like the cornerstone, while cryptocurrencies such as Bitcoin are niche products. It is foreseeable that with the de-globalization, cryptocurrency will expand to many more areas for new applications.
From an engineering perspective, the crypto ecosystem is continuously improving. Better development tools and easier-to-use components allow developers to implement lego-style infrastructures. Although the security of interoperability needs to be improved urgently, the infrastructure and applications themselves are spiraling upwards.There’s no doubt that when we look back in five years, the current hurdles like security, interoperability, and privacy will be no more.
Privacy-preserving computation is developing rapidly, and the new protocol in academia has increased computation efficiency to meet commercial needs. Various countries are gradually implementing regulations, and some large companies are also exploring and formulating industry standards with ARPA. Blockchain and the privacy-preserving computation industry’s rapid progress gives ARPA a strong foundation to develop.

https://preview.redd.it/hxc1k9h6pny41.png?width=1400&format=png&auto=webp&s=b3ae5dfd6cac27771e1250d2a3ee725c2929de5c
In 2020, the primary goal of a large number of companies is to survive. Cycle management is, in my opinion, the secret of success in any business. The financial cycle, the singularity of privacy-preserving computation technology and the regulatory change in the data industry are the three cycles of the industry where ARPA is in.
ARPA is powered by an agile and elite team. We are highly selective when it comes to recruitment and partnerships. Over the past two years, ARPA participated in the formulation of privacy-preserving computation industry standards, assisted the authoritative institutions such as the China Academy of Information and Communication Technology(CAICT) and IEEE in promoting the development of the privacy-preserving computation, and participated in the authoring of the first book on privacy-computation in China. It allows ARPA to maintain thought leadership and leading standards in the emerging industry of privacy-preserving computation.
Looking ahead to the coming year, the ARPA team will continue to thrive in the privacy-preserving computation industry, expand partnerships in the financial and marketing sectors, and continue to launch products such as blacklist sharing and joint risk control.
We will continue exploring crypto-native use cases, such as open finance and DeFi products, decentralized cross-chain asset custody. For example, ARPA’s threshold signature technology that’s based on MPC can enable distributed key management (DKMS), realize decentralized cryptocurrency custody, and better protect user assets. Threshold signature applications include enterprise-level
