Large is an open source peer-to-peer blogging platform that helps you build apps and websites that are hosted by the people that use them. Built on IPFS, OrbitDB, and Ethereum.

For the past year I've been working on a toolkit to make it easy to combine these different technologies to build applications that are hosted with IPFS. A few months ago I discovered OrbitDB which has really connected a lot of the dots.
Large is built on top of IPFS and Ethereum.
Right now I'm working on a Twitter-like prototype. Most of the basic functionality works but it's super rough around the edges. There are a whole lot of bugs still, but I've made a whole lot of progress over the past couple of months.
Over the next couple of weeks I'm going to be building out some code-along tutorials to show people how to use this to build real apps. All of the data is hosted on the machine where the app is running. Orbit allows you to load remote databases and send data to any peers you decide to connect to. In order to connect to a peer you just need their wallet public key.
I've been trying to separate the data services out enough so that you're not actually tied to the things that I prefer to use for the front-end.
https://gitlab.com/ptonelarge <- The prototype Twitter clone
https://gitlab.com/ptonelarge-core <- P2P data services
Documentation is still rough and some things are probably old and inaccurate. I'm writing + fixing it as fast as I can.
I love IPFS and want to make it easy to build stuff with it. I appreciate any feedback.

The Goal
Short Term Goal:
Reddit/Ethereum Scalability and Resource Efficiency via Blockchain Interoperability
Team DAPP Solutions would like to start by saluting Team Reddit for leading the charge in mass adoption of blockchain technologies. We will show our appreciation by developing a Reddit Community Points solution that is verifiably inexpensive, scalable and secure.
Long Term Goal:
Blockchain Agnosticism | One Network
It is a sincere pleasure for us at Team DAPP Solutions to be engaging directly with the Reddit and Ethereum communities. Those of us familiar and engaged with the LiquidApps DAPP Network have waited patiently to showcase our unique and differentiated services towards a positive sum gain for all.
Interoperability | InterBlockchain Communication (IBC)
On July 26, 2019, CryptoTwitter was treated to a demonstration by the LiquidApps Team of blockchain interoperability using a DAPP Network service called LiquidLink.
Link here:
https://twitter.com/LiquidAppsIO/status/1154842918705926145?s=20
Our slogan at DAPP Solutions since our inception is “Onboard Everyone”, so we were very excited last July to watch blockchain interoperability come to fruition between the Ethereum and EOSIO-based blockchains.
The DAPP Solutions Team is excited to be able to introduce Reddit and the greater Ethereum community to the LiquidLink bridge between Ethereum and EOSIO. This DAPP Network service leverages the benefits and communities of both technologies in moving towards the greater goal of interoperable, scaleable and decentralized blockchain solutions.
Submission Timeline Explained:
As you review our proposal, please understand that we entered this challenge on July 11, following the LiquidApps July, 6 code upgrade to LiquidLink, and accompanying Medium article,(https://medium.com/the-liquidapps-blog/the-dapp-networks-reddit-scaling-bounty-d60e057de6d) specifically upgraded to take on the challenge of the Great Reddit Scaling Bake-Off.
The article echos our sentiments at DAPP Solutions:
“Despite getting the ball rolling on Ethereum scalability, Reddit isn’t the only one that can benefit from the DAPP Network’s unique cross-chain middleware. Any Ethereum project that wishes to scale without leaving its native ecosystem, could utilize such a mechanism to go where no dApp has gone before — mass usage.”
With limited time and resources available to us, we chose to focus on interoperability, scalability and resource efficiency with the intention of integrating with one or more existing wallets by the time submissions are reviewed and chosen.
Now with an upgraded version of LiquidLink, we set out to show our blockchain brethren what our tools can do. Our solution relies on the EOSIO infrastructure, as well as a L2 solution called the DAPP network to scale the EOSIO network’s capabilities and resource management.
Our goal in providing this POC is to demonstrate how the DAPP Network can act as a live, advanced middleware to scale the Reddit Ethereum model while ensuring resource and cost efficiency.
Demos Should Include:
  1. A live proof of concept showing hundreds of thousands of transactions. (Pending)
  2. Source Code (See GitHub link above)
  3. Documentation:
  4. How it Works and Scales:
  • Ethereum for distributing/minting tokens in ERC-20 format when users want to remove them to popular Ethereum wallets, as well as token burning when users send funds back to the account for re-entry into the EOSIO/DAPP side of the system.
  • EOSIO storage/computation to manage user balances, community distributions, purchased community features and other community functions that feed into the user balance system upon a successful round of user distribution (via karma/voting as the system is currently implemented on reddit).
  • The DAPP network for its ability to call Ethereum networks through a service called LiquidLink, which allows us to make calls to ethereum at regular intervals to update the latest IPFS hash tip. This lets us store the latest version of the memory implementation so that any DSP running the LiquidApps contract logic will be able to rebuild and continue to run the system.
  • The DAPP network for vRAM which uses IPFS to scale the storage potential of an EOSIO contract, making the upper-limit and resource usage of the contract as minimal as possible. This storage object has a hash for the latest entry which can be used when storing on ethereum.
  • The DAPP network LiquidOracle for Oracle services, in order to determine if user balances have been submitted back into the system (burned on the Ethereum contract and re-assigned to the user in EOSIO storage).
  • The DAPP network for LiquidScheduler, a cron-job library for calling ethereum at regular intervals to update the IPFS hash and to execute anything needed on the ethereum network.
  1. Cost Estimates (on-chain and off-chain):
Comparable metrics will be posted to the demo page, which will be linked from the github. (pending)
EOSIO requires that system tokens be assigned to the contract (EOS on the EOS mainnet) for CPU, RAM, and NET. Both CPU and NET usage limits are returned to the account (linear timeline to return of resources), which is similar to the DAPP token in that once these tokens are staked, you can increase your stake in a given resource when needed, however they can be returned/un-staked and sold - so while there is an initial setup cost, the ongoing costs will be greatly reduced, and largely predictable.
Anyone can add resources to the contract when usage increases, these resources can all be unstaked/sold if usage decreases, or if a new contract is introduced to manage the system etc. RAM on EOSIO is bought and sold on an internal market, and does have an upper-limit.
However, the vRAM solution through the DAPP network will allow us to remove this upper-limit, and convert it into a quota of X number of calls for Y number of DAPP tokens, which can be modified accordingly without requiring more (or in some cases, a minor amount of) EOSIO RAM resources.
  1. How to Run It
Using our reddit simulator, and our demo page (pending), a web UI will be used to trigger the simulation while tweaking variables for efficiency.
  1. Architecture
  • An Ethereum smart contract (existing SubReddit token contract) to be called for minting, distributing, and burning tokens per community, as well as storing the latest IPFS hash from the DSP.
  • An EOSIO/DAPP smart contract which manages the community points system. This contract is interpreted first by a DSP (with consensus across multiple DSPs if needed for consensus checks to decentralize trust in a single DSP), then passed along to EOSIO for on-chain processing.
    • User balances and subscriptions/purchases/sending of tokens between users.
    • Community descriptions e.g. symbol, ETH contract address, and any other info needed (such as URLs for icons and other cosmetic community variables)
    • Management of community distributions to users upon a submitted list.
    • Calling the ethereum contract to mint/issue tokens to users that want to exit the system to an existing wallet.
    • Calling the ethereum contract to update the latest IPFS hash for recreating the data (in case of any issue at the DSP level, the data inside the contract can be re-created from this hash).
  • A node.js/postgres reddit simulation engine to generate user accounts with ethereum addresses, issue them karma, then distribute tokens according to karma rankings (recipient list approval not included). It is currently acting as our user ethereum wallets for testing purposes, and otherwise seeks only to replicate and randomize reddit usage in relation to the community point system.
  1. API’s (on chain & off) : Ver 1.0 N/A We have built a Reddit Community Point Simulation
    1. End-User Case
Dependent on wallet collaboration/integration for API to connect to reddit.
  1. Known Issues:
Pending:
  • A demo including an end-user interface for signing transactions with their ethereum-based wallet.
    • Code attached to submission for how to use same private key for both EOSIO and Ethereum accounts, easily implementable for any existing ethereum wallet to support calling both EOSIO and Ethereum-based chains using a shared private key across networks.
  • To link ethereum point burning back to user balances in the system.
    • Also a plan for integration using the DAPP network’s LiquidOracles implementation to check what tokens have been burned, and from what address, so that the EOSIO/DAPP model can update the user account’s balances to reflect changes in subscriptions and purchase of community features.
  • Comparative metric outputs (and easily able to be run in a random manner in regards to user accounts and community interactions to ensure consistency, which is already in the simulation code).
  • Functional demo page to be completed - linked on github.
Requirements
Scaling:
Our PoC (redditdapp.cpp) and test contract (main.cpp) currently tests and has consumed all necessary services to meet the requirements:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We are in the process of setting up our live demo page to show the system in action, which we will put onto the github repo in the coming days, so be sure to check back!
Decentralization
DSPs are chosen by the EOSIO/DAPP contract owner (which would be reddit in this submission’s case), however many DSPs can be selected by that contract and utilized to create consensus amongst calls, as well as to decentralize the trust desired/required when working with them across many parties.Through a combination of these services, we can decentralize every part of the system.
Useability:
While we still require a wallet to integrate with our solution, our Reddit Simulation Server is mimicking wallets for the sake of demonstration. Outside of this implementation, the system self-manages assuming there are enough resources (both for gas fees on ETH and for account/network resources on EOSIO/DAPP).
Interoperability:
Using LiquidLink and LiquidOracles, we can both sign transactions on, and listen to the Ethereum blockchain as shown in linked examples/articles above.
Security:
All systems require private keys to interact with the contracts, and otherwise will only run on a scheduler. So long as private keys are only held for account resource management
Resource Efficiency
Through the usage of vRAM and EOSIO accounts, there are no TX fees outside of moving tokens onto/off of the Ethereum network.
The vRAM/LiquidLink/Oracles/Scheduler model requires that DAPP tokens be staked to a DAPP Service Provider (DSP), which must increase according to usage, but can be un-staked at any time.
Strengths of this approach
Cost/Resource Efficiency
Without the need for transaction fees at every interaction in the system on the
Ethereum network, we should be able to bring a majority of system costs to a minimum. None of the fees inside of the EOSIO/DAPP system are “spent” in the sense of transaction fees, and are refundable in the form of EOSIO system and DAPP tokens. These networks provide a much higher throughput at a much lower cost. The only time gas fees would need to be spent would be the update interval for the IPFS hash (sped up for simulation purposes, but this interval can be set to any amount of time), then token minting/issuing/burning gas fees should a user decide to exit or enter the system using an ERC-20 wallet. This implementation is also easily port-able to EOSIO tokens, which would speed up the system and remove transaction fees from the system entirely.
Flow of operations:
Community Perspective
  1. Community (reddit systems, not users) registers a subreddit with system (EOSIO) and loads the ERC-20 token contract onto an ethereum address for that community point/token (ETH) and to mint an initial supply for the ETH contract.
  2. Reddit submits token distribution per-month/round and includes user info, as well as community/token amount to the EOSIO contract (EOSIO), which then uses vRAM (DAPP) to query and store the information.
  3. LiquidScheduler runs on interval to check what events are queued to go out to Ethereum upon being triggered (DAPP)
  4. If any users have asked to exit the system (EOSIO), the queue is run through the LiquidLink service (DAPP) to send a signature to ethereum to send tokens to their ETH accounts (ETH receive).
  5. To re-enter the system, users can send funds back to the community contract to be burned (ETH).
  6. During the LiquidScheduler interval check, it will call the LiquidOracle service (DAPP) to check for sends/token burns.
  7. If any burns are found, it will match the ETH address to the user account and add the funds back into their account (EOSIO/DAPP).
User Perspective (Dependent on cross-chain key signing wallet support)
  1. User receives community points from distribution rounds. (Reddit -> EOSIO)
  2. User can choose to subscribe to a community, or buy community features with tokens or fiat.
    1. If fiat, ETH contract will be called using LiquidLink to burn tokens (DAPP -> ETH)
    2. If purchasing with tokens, vRAM records will be updated to deduct from the user’s balance without adding them elsewhere. (DAPP)
      1. These actions would be signed using an integration of the keycode.js file (included in github “wallet” folder)
  3. Can send tokens from one user to another, using a wallet implementation of keycode.js to verify before moving balances (EOSIO and potentially ETH depending on final wallet solution).
  4. Can select a set of community points to exit the system into their wallet (Wallet -> DAPP -> ETH)
  5. Can send tokens to the community’s ETH address to re-enter the system, no burn needed from ETH in this case, so long as the initial token supply is minted on Ethereum (ETH)
  6. LiquidOracle Service will read ethereum network to check for received tokens to update vRAM for user balance. (DAPP)

CAP (Collateralized Asset Protocol) Update *Beta Launched + Roadmap*

As stated in my last post the Beta is currently being tested by the telegram community!
https://www.coingecko.com/en/coins/cap

[Text from the roadmap released today - read here at https://blog.cap.finance/2020/09/02/the-roadmap.html]
"This post lays out a 10 year roadmap for Cap. Our goal is to build open, decentralized financial services with CAP as the native token.
We consider this to be such an important mission because of its huge disruptive potential. For the first time in history, we have the opportunity to build unstoppable financial services governed by fair and open rules, as opposed to the current centralized and opaque financial system that underpins almost every aspect of our society.
Here’s what we plan to do to achieve that vision.

Perpetuals

The Cap ecosystem starts with Cap Perpetuals, which we launched in August.
Perpetuals let you open leveraged long or short positions on certain markets using stablecoins such as DAI. Profits are backed by the Cap Liquidity Pool (CLP), which in turn receives trader losses. Yield generated by the CLP is used to buy back CAP.
The current iteration of Perpetuals is semi-decentralized. Things like price feeds and liquidations are managed by our server to ensure speed and predictability of execution. We believe that a semi-decentralized form of the Perpetuals product will be desirable for the foreseeable future, particularly for traders who are speed-sensitive.
A fully decentralized Perpetuals design is possible and planned. Price feeds are provided by independent oracles while liquidations are monitored and managed by anyone willing to do so in exchange for a fee. This design is not trivial and issues like oracle front-running, which can result in riskless profit, as well as informed trading flow, which can drain the CLP, will need to be dealt with accordingly.
Perpetuals generate sustainable revenue that allows us to go after higher risk markets as described below.

Synthetics

Synthetics are crypto-backed instruments that track the value of an underlying asset, like a stock. They let you gain exposure to an asset without needing to own it, and without interacting with the traditional financial system, saving time and money.
Cap Synthetics are non-leveraged, withdrawable ERC-20 tokens that you can purchase using stablecoins. They are backed by the CLP and their price is determined by oracle feeds.
To purchase a synthetic, you send an amount of stablecoins to our Synthetics contract. The contract determines the price of the asset you’re trying to buy based on its oracle feed and mints the equivalent amount of tokens to your address.
To sell a synthetic, you send your asset tokens to our Synthetics contract, which determines the amount of stablecoins to send to you based on the oracle feed. The tokens you send are then burned.
We plan to release a proof of concept for our Synthetics product some time in September. The goal is end-to-end decentralization. The backend logic is executed entirely in smart contracts and client side code is hosted on IPFS, accessible through an unstoppable .crypto domain.

Exchange

A token exchange will be part of the Cap ecosystem. It will be decentralized and function similarly to Uniswap, with a few differences, including a more efficient market maker based on our technical whitepaper.
In short, Cap Exchange will have a market maker that will adapt its liquidity curve based on the type of assets being exchanged. For example, a volatile asset pair would have a more sensitive spread than a non volatile one, resulting in a superior experience for traders while protecting liquidity providers.

Lending

Lending and borrowing are the pillars of the current financial system. Several protocols today operate overcollateralized lending on Ethereum, but we believe a much larger market exists in undercollateralized lending coupled with credit (reputation) and identity.
Cap Lending will be built in conjunction with a decentralized reputation system that will allow lenders to evaluate borrowers from a risk perspective on a case by case basis. Decentralized, unsecured lending is not trivial but we believe we’ve come up with a design to make it work.

More

Several other services will also be built under the Cap umbrella. Those include staking, asset management, prediction markets, identity, insurance, and gaming. Admittedly, many of the implementation details for these products are still TBD, but we trust we will figure them out in due time.
We also plan to build traditional infrastructure services that interact directly with smart contracts on the blockchain, including oracles, to support Cap’s smart contracts without needing to rely on and pay for an external third party in the long run. Cap Oracles will be an independently run entity.
CAP is the native token underpinning the entire ecosystem. CAP holders will not only be entitled to the global yield generated by the system, but they will also be able to vote on system parameters and asset offerings, among other things. The point of Cap is to create a financial system governed by its users and the CAP token makes that possible.
Cap’s values are:
We plan to build out Cap with those values in mind. Focusing on the core features that matter to most users. Continuously engaging with the community in a transparent manner. Getting high-impact smart contracts audited by competent third parties prior to wide usage. And more.
Cap is community driven. Join us on Telegram."

RESEARCH REPORT ABOUT KYBER NETWORK

RESEARCH REPORT ABOUT KYBER NETWORK
Author: Gamals Ahmed, CoinEx Business Ambassador

https://preview.redd.it/9k31yy1bdcg51.jpg?width=936&format=pjpg&auto=webp&s=99bcb7c3f50b272b7d97247b369848b5d8cc6053

ABSTRACT

In this research report, we present a study on Kyber Network. Kyber Network is a decentralized, on-chain liquidity protocol designed to make trading tokens simple, efficient, robust and secure.
Kyber design allows any party to contribute to an aggregated pool of liquidity within each blockchain while providing a single endpoint for takers to execute trades using the best rates available. We envision a connected liquidity network that facilitates seamless, decentralized cross-chain token swaps across Kyber based networks on different chains.
Kyber is a fully on-chain liquidity protocol that enables decentralized exchange of cryptocurrencies in any application. Liquidity providers (Reserves) are integrated into one single endpoint for takers and users. When a user requests a trade, the protocol will scan the entire network to find the reserve with the best price and take liquidity from that particular reserve.

1.INTRODUCTION

DeFi applications all need access to good liquidity sources, which is a critical component to provide good services. Currently, decentralized liquidity is comprised of various sources including DEXes (Uniswap, OasisDEX, Bancor), decentralized funds and other financial apps. The more scattered the sources, the harder it becomes for anyone to either find the best rate for their trade or to even find enough liquidity for their need.
Kyber is a blockchain-based liquidity protocol that aggregates liquidity from a wide range of reserves, powering instant and secure token exchange in any decentralized application.
The protocol allows for a wide range of implementation possibilities for liquidity providers, allowing a wide range of entities to contribute liquidity, including end users, decentralized exchanges and other decentralized protocols. On the taker side, end users, cryptocurrency wallets, and smart contracts are able to perform instant and trustless token trades at the best rates available amongst the sources.
The Kyber Network is project based on the Ethereum protocol that seeks to completely decentralize the exchange of crypto currencies and make exchange trustless by keeping everything on the blockchain.
Through the Kyber Network, users should be able to instantly convert or exchange any crypto currency.

1.1 OVERVIEW ABOUT KYBER NETWORK PROTOCOL

The Kyber Network is a decentralized way to exchange ETH and different ERC20 tokens instantly — no waiting and no registration needed.
Using this protocol, developers can build innovative payment flows and applications, including instant token swap services, ERC20 payments, and financial DApps — helping to build a world where any token is usable anywhere.
Kyber’s fully on-chain design allows for full transparency and verifiability in the matching engine, as well as seamless composability with DApps, not all of which are possible with off-chain or hybrid approaches. The integration of a large variety of liquidity providers also makes Kyber uniquely capable of supporting sophisticated schemes and catering to the needs of DeFi DApps and financial institutions. Hence, many developers leverage Kyber’s liquidity pool to build innovative financial applications, and not surprisingly, Kyber is the most used DeFi protocol in the world.
The Kyber Network is quite an established project that is trying to change the way we think of decentralised crypto currency exchange.
The Kyber Network has seen very rapid development. After being announced in May 2017 the testnet for the Kyber Network went live in August 2017. An ICO followed in September 2017, with the company raising 200,000 ETH valued at $60 million in just one day.
The live main net was released in February 2018 to whitelisted participants, and on March 19, 2018, the Kyber Network opened the main net as a public beta. Since then the network has seen increasing growth, with network volumes growing more than 500% in the first half of 2019.
Although there was a modest decrease in August 2019 that can be attributed to the price of ETH dropping by 50%, impacting the overall total volumes being traded and processed globally.
They are developing a decentralised exchange protocol that will allow developers to build payment flows and financial apps. This is indeed quite a competitive market as a number of other such protocols have been launched.
In Brief - Kyber Network is a tool that allows anyone to swap tokens instantly without having to use exchanges. - It allows vendors to accept different types of cryptocurrency while still being paid in their preferred crypto of choice. - It’s built primarily for Ethereum, but any smart-contract based blockchain can incorporate it.
At its core, Kyber is a decentralized way to exchange ETH and different ERC20 tokens instantly–no waiting and no registration needed. To do this Kyber uses a diverse set of liquidity pools, or pools of different crypto assets called “reserves” that any project can tap into or integrate with.
A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go.
All this swapping happens directly on the Ethereum blockchain, meaning every transaction is completely transparent.

1.1.1 WHY BUILD THE KYBER NETWORK?

While crypto currencies were built to be decentralized, many of the exchanges for trading crypto currencies have become centralized affairs. This has led to security vulnerabilities, with many exchanges becoming the victims of hacking and theft.
It has also led to increased fees and costs, and the centralized exchanges often come with slow transfer times as well. In some cases, wallets have been locked and users are unable to withdraw their coins.
Decentralized exchanges have popped up recently to address the flaws in the centralized exchanges, but they have their own flaws, most notably a lack of liquidity, and often times high costs to modify trades in their on-chain order books.

Some of the Integrations with Kyber Protocol
The Kyber Network was formed to provide users with a decentralized exchange that keeps everything right on the blockchain, and uses a reserve system rather than an order book to provide high liquidity at all times. This will allow for the exchange and transfer of any cryptocurrency, even cross exchanges, and costs will be kept at a minimum as well.
The Kyber Network has three guiding design philosophies since the start:
  1. To be most useful the network needs to be platform-agnostic, which allows any protocol or application the ability to take advantage of the liquidity provided by the Kyber Network without any impact on innovation.
  2. The network was designed to make real-world commerce and decentralized financial products not only possible but also feasible. It does this by allowing for instant token exchange across a wide range of tokens, and without any settlement risk.
  3. The Kyber Network was created with ease of integration as a priority, which is why everything runs fully on-chain and fully transparent. Kyber is not only developer-friendly, but is also compatible with a wide variety of systems.

1.1.2 WHO INVENTED KYBER?

Kyber’s founders are Loi Luu, Victor Tran, Yaron Velner — CEO, CTO, and advisor to the Kyber Network.

1.1.3 WHAT DISTINGUISHES KYBER?

Kyber’s mission has always been to integrate with other protocols so they’ve focused on being developer-friendly by providing architecture to allow anyone to incorporate the technology onto any smart-contract powered blockchain. As a result, a variety of different dapps, vendors, and wallets use Kyber’s infrastructure including Set Protocol, bZx, InstaDApp, and Coinbase wallet.
Besides, dapps, vendors, and wallets, Kyber also integrates with other exchanges such as Uniswap — sharing liquidity pools between the two protocols.
A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go.
Limit orders on Kyber allow users to set a specific price in which they would like to exchange a token instead of accepting whatever price currently exists at the time of trading. However, unlike with other exchanges, users never lose custody of their crypto assets during limit orders on Kyber.
The Kyber protocol works by using pools of crypto funds called “reserves”, which currently support over 70 different ERC20 tokens. Reserves are essentially smart contracts with a pool of funds. Different parties with different prices and levels of funding control all reserves. Instead of using order books to match buyers and sellers to return the best price, the Kyber protocol looks at all the reserves and returns the best price among the different reserves. Reserves make money on the “spread” or differences between the buying and selling prices. The Kyber wants any token holder to easily convert one token to another with a minimum of fuss.

1.2 KYBER PROTOCOL

The protocol smart contracts offer a single interface for the best available token exchange rates to be taken from an aggregated liquidity pool across diverse sources. ● Aggregated liquidity pool. The protocol aggregates various liquidity sources into one liquidity pool, making it easy for takers to find the best rates offered with one function call. ● Diverse sources of liquidity. The protocol allows different types of liquidity sources to be plugged into. Liquidity providers may employ different strategies and different implementations to contribute liquidity to the protocol. ● Permissionless. The protocol is designed to be permissionless where any developer can set up various types of reserves, and any end user can contribute liquidity. Implementations need to take into consideration various security vectors, such as reserve spamming, but can be mitigated through a staking mechanism. We can expect implementations to be permissioned initially until the maintainers are confident about these considerations.
The core feature that the Kyber protocol facilitates is the token swap between taker and liquidity sources. The protocol aims to provide the following properties for token trades: ● Instant Settlement. Takers do not have to wait for their orders to be fulfilled, since trade matching and settlement occurs in a single blockchain transaction. This enables trades to be part of a series of actions happening in a single smart contract function. ● Atomicity. When takers make a trade request, their trade either gets fully executed, or is reverted. This “all or nothing” aspect means that takers are not exposed to the risk of partial trade execution. ● Public rate verification. Anyone can verify the rates that are being offered by reserves and have their trades instantly settled just by querying from the smart contracts. ● Ease of integration. Trustless and atomic token trades can be directly and easily integrated into other smart contracts, thereby enabling multiple trades to be performed in a smart contract function.
How each actor works is specified in Section Network Actors. 1. Takers refer to anyone who can directly call the smart contract functions to trade tokens, such as end-users, DApps, and wallets. 2. Reserves refer to anyone who wishes to provide liquidity. They have to implement the smart contract functions defined in the reserve interface in order to be registered and have their token pairs listed. 3. Registered reserves refer to those that will be cycled through for matching taker requests. 4. Maintainers refer to anyone who has permission to access the functions for the adding/removing of reserves and token pairs, such as a DAO or the team behind the protocol implementation. 5. In all, they comprise of the network, which refers to all the actors involved in any given implementation of the protocol.
The protocol implementation needs to have the following: 1. Functions for takers to check rates and execute the trades 2. Functions for the maintainers to registeremove reserves and token pairs 3. Reserve interface that defines the functions reserves needs to implement

1.3 KYBER CORE SMART CONTRACTS

Kyber Core smart contracts is an implementation of the protocol that has major protocol functions to allow actors to join and interact with the network. For example, the Kyber Core smart contracts provide functions for the listing and delisting of reserves and trading pairs by having clear interfaces for the reserves to comply to be able to register to the network and adding support for new trading pairs. In addition, the Kyber Core smart contracts also provide a function for takers to query the best rate among all the registered reserves, and perform the trades with the corresponding rate and reserve. A trading pair consists of a quote token and any other token that the reserve wishes to support. The quote token is the token that is either traded from or to for all trades. For example, the Ethereum implementation of the Kyber protocol uses Ether as the quote token.
In order to search for the best rate, all reserves supporting the requested token pair will be iterated through. Hence, the Kyber Core smart contracts need to have this search algorithm implemented.
The key functions implemented in the Kyber Core Smart Contracts are listed in Figure 2 below. We will visit and explain the implementation details and security considerations of each function in the Specification Section.

1.4 HOW KYBER’S ON-CHAIN PROTOCOL WORKS?

Kyber is the liquidity infrastructure for decentralized finance. Kyber aggregates liquidity from diverse sources into a pool, which provides the best rates for takers such as DApps, Wallets, DEXs, and End users.

1.4.1 PROVIDING LIQUIDITY AS A RESERVE

Anyone can operate a Kyber Reserve to market make for profit and make their tokens available for DApps in the ecosystem. Through an open reserve architecture, individuals, token teams and professional market makers can contribute token assets to Kyber’s liquidity pool and earn from the spread in every trade. These tokens become available at the best rates across DApps that tap into the network, making them instantly more liquid and useful.
MAIN RESERVE TYPES Kyber currently has over 45 reserves in its network providing liquidity. There are 3 main types of reserves that allow different liquidity contribution options to suit the unique needs of different providers. 1. Automated Price Reserves (APR) — Allows token teams and users with large token holdings to have an automated yet customized pricing system with low maintenance costs. Synthetix and Melon are examples of teams that run APRs. 2. Fed Price Reserves (FPR) — Operated by professional market makers that require custom and advanced pricing strategies tailored to their specific needs. Kyber alongside reserves such as OneBit, runs FPRs. 3. Bridge Reserves (BR) — These are specialized reserves meant to bring liquidity from other on-chain liquidity providers like Uniswap, Oasis, DutchX, and Bancor into the network.

1.5 KYBER NETWORK ROLES

There Kyber Network functions through coordination between several different roles and functions as explained below: - Users — This entity uses the Kyber Network to send and receive tokens. A user can be an individual, a merchant, and even a smart contract account. - Reserve Entities — This role is used to add liquidity to the platform through the dynamic reserve pool. Some reserve entities are internal to the Kyber Network, but others may be registered third parties. Reserve entities may be public if the public contributes to the reserves they hold, otherwise they are considered private. By allowing third parties as reserve entities the network adds diversity, which prevents monopolization and keeps exchange rates competitive. Allowing third party reserve entities also allows for the listing of less popular coins with lower volumes. - Reserve Contributors — Where reserve entities are classified as public, the reserve contributor is the entity providing reserve funds. Their incentive for doing so is a profit share from the reserve. - The Reserve Manager — Maintains the reserve, calculates exchange rates and enters them into the network. The reserve manager profits from exchange spreads set by them on their reserves. They can also benefit from increasing volume by accessing the entire Kyber Network. - The Kyber Network Operator — Currently the Kyber Network team is filling the role of the network operator, which has a function to adds/remove Reserve Entities as well as controlling the listing of tokens. Eventually, this role will revert to a proper decentralized governance.

1.6 BASIC TOKEN TRADE

A basic token trade is one that has the quote token as either the source or destination token of the trade request. The execution flow of a basic token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for ETH as an example. The trade happens in a single blockchain transaction. 1. Taker sends 1 ETH to the protocol contract, and would like to receive BAT in return. 2. Protocol contract queries the first reserve for its ETH to BAT exchange rate. 3. Reserve 1 offers an exchange rate of 1 ETH for 800 BAT. 4. Protocol contract queries the second reserve for its ETH to BAT exchange rate. 5. Reserve 2 offers an exchange rate of 1 ETH for 820 BAT. 6. This process goes on for the other reserves. After the iteration, reserve 2 is discovered to have offered the best ETH to BAT exchange rate. 7. Protocol contract sends 1 ETH to reserve 2. 8. The reserve sends 820 BAT to the taker.

1.7 TOKEN-TO-TOKEN TRADE

A token-to-token trade is one where the quote token is neither the source nor the destination token of the trade request. The exchange flow of a token to token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for DAI as an example. The trade happens in a single blockchain transaction. 1. Taker sends 50 BAT to the protocol contract, and would like to receive DAI in return. 2. Protocol contract sends 50 BAT to the reserve offering the best BAT to ETH rate. 3. Protocol contract receives 1 ETH in return. 4. Protocol contract sends 1 ETH to the reserve offering the best ETH to DAI rate. 5. Protocol contract receives 30 DAI in return. 6. Protocol contract sends 30 DAI to the user.

2.KYBER NETWORK CRYSTAL (KNC) TOKEN

Kyber Network Crystal (KNC) is an ERC-20 utility token and an integral part of Kyber Network.
KNC is the first deflationary staking token where staking rewards and token burns are generated from actual network usage and growth in DeFi.
The Kyber Network Crystal (KNC) is the backbone of the Kyber Network. It works to connect liquidity providers and those who need liquidity and serves three distinct purposes. The first of these is to collect transaction fees, and a portion of every fee collected is burned, which keeps KNC deflationary. Kyber Network Crystals (KNC), are named after the crystals in Star Wars used to power light sabers.
The KNC also ensures the smooth operation of the reserve system in the Kyber liquidity since entities must use third-party tokens to buy the KNC that pays for their operations in the network.
KNC allows token holders to play a critical role in determining the incentive system, building a wide base of stakeholders, and facilitating economic flow in the network. A small fee is charged each time a token exchange happens on the network, and KNC holders get to vote on this fee model and distribution, as well as other important decisions. Over time, as more trades are executed, additional fees will be generated for staking rewards and reserve rebates, while more KNC will be burned. - Participation rewards — KNC holders can stake KNC in the KyberDAO and vote on key parameters. Voters will earn staking rewards (in ETH) - Burning — Some of the network fees will be burned to reduce KNC supply permanently, providing long-term value accrual from decreasing supply. - Reserve incentives — KNC holders determine the portion of network fees that are used as rebates for selected liquidity providers (reserves) based on their volume performance.

Finally, the KNC token is the connection between the Kyber Network and the exchanges, wallets, and dApps that leverage the liquidity network. This is a virtuous system since entities are rewarded with referral fees for directing more users to the Kyber Network, which helps increase adoption for Kyber and for the entities using the Network.
And of course there will soon be a fourth and fifth uses for the KNC, which will be as a staking token used to generate passive income, as well as a governance token used to vote on key parameters of the network.
The Kyber Network Crystal (KNC) was released in a September 2017 ICO at a price around $1. There were 226,000,000 KNC minted for the ICO, with 61% sold to the public. The remaining 39% are controlled 50/50 by the company and the founders/advisors, with a 1 year lockup period and 2 year vesting period.
Currently, just over 180 million coins are in circulation, and the total supply has been reduced to 210.94 million after the company burned 1 millionth KNC token in May 2019 and then its second millionth KNC token just three months later.
That means that while it took 15 months to burn the first million KNC, it took just 10 weeks to burn the second million KNC. That shows how rapidly adoption has been growing recently for Kyber, with July 2019 USD trading volumes on the Kyber Network nearly reaching $60 million. This volume has continued growing, and on march 13, 2020 the network experienced its highest daily trading activity of $33.7 million in a 24-hour period.
Currently KNC is required by Reserve Managers to operate on the network, which ensures a minimum amount of demand for the token. Combined with future plans for burning coins, price is expected to maintain an upward bias, although it has suffered along with the broader market in 2018 and more recently during the summer of 2019.
It was unfortunate in 2020 that a beginning rally was cut short by the coronavirus pandemic, although the token has stabilized as of April 2020, and there are hopes the rally could resume in the summer of 2020.

2.1 HOW ARE KNC TOKENS PRODUCED?

The native token of Kyber is called Kyber Network Crystals (KNC). All reserves are required to pay fees in KNC for the right to manage reserves. The KNC collected as fees are either burned and taken out of the total supply or awarded to integrated dapps as an incentive to help them grow.

2.2 HOW DO YOU GET HOLD OF KNC TOKENS?

Kyber Swap can be used to buy ETH directly using a credit card, which can then be used to swap for KNC. Besides Kyber itself, exchanges such as Binance, Huobi, and OKex trade KNC.

2.3 WHAT CAN YOU DO WITH KYBER?

The most direct and basic function of Kyber is for instantly swapping tokens without registering an account, which anyone can do using an Etheruem wallet such as MetaMask. Users can also create their own reserves and contribute funds to a reserve, but that process is still fairly technical one–something Kyber is working on making easier for users in the future.

2.4 THE GOAL OF KYBER THE FUTURE

The goal of Kyber in the coming years is to solidify its position as a one-stop solution for powering liquidity and token swapping on Ethereum. Kyber plans on a major protocol upgrade called Katalyst, which will create new incentives and growth opportunities for all stakeholders in their ecosystem, especially KNC holders. The upgrade will mean more use cases for KNC including to use KNC to vote on governance decisions through a decentralized organization (DAO) called the KyberDAO.
With our upcoming Katalyst protocol upgrade and new KNC model, Kyber will provide even more benefits for stakeholders. For instance, reserves will no longer need to hold a KNC balance for fees, removing a major friction point, and there will be rebates for top performing reserves. KNC holders can also stake their KNC to participate in governance and receive rewards.

2.5 BUYING & STORING KNC

Those interested in buying KNC tokens can do so at a number of exchanges. Perhaps your best bet between the complete list is the likes of Coinbase Pro and Binance. The former is based in the USA whereas the latter is an offshore exchange.
The trading volume is well spread out at these exchanges, which means that the liquidity is not concentrated and dependent on any one exchange. You also have decent liquidity on each of the exchange books. For example, the Binance BTC / KNC books are wide and there is decent turnover. This means easier order execution.
KNC is an ERC20 token and can be stored in any wallet with ERC20 support, such as MyEtherWallet or MetaMask. One interesting alternative is the KyberSwap Android mobile app that was released in August 2019.
It allows for instant swapping of tokens and has support for over 70 different altcoins. It also allows users to set price alerts and limit orders and works as a full-featured Ethereum wallet.

2.6 KYBER KATALYST UPGRADE

Kyber has announced their intention to become the de facto liquidity layer for the Decentralized Finance space, aiming to have Kyber as the single on-chain endpoint used by the majority of liquidity providers and dApp developers. In order to achieve this goal the Kyber Network team is looking to create an open ecosystem that garners trust from the decentralized finance space. They believe this is the path that will lead the majority of projects, developers, and users to choose Kyber for liquidity needs. With that in mind they have recently announced the launch of a protocol upgrade to Kyber which is being called Katalyst.
The Katalyst upgrade will create a stronger ecosystem by creating strong alignments towards a common goal, while also strengthening the incentives for stakeholders to participate in the ecosystem.
The primary beneficiaries of the Katalyst upgrade will be the three major Kyber stakeholders: 1. Reserve managers who provide network liquidity; 2. dApps that connect takers to Kyber; 3. KNC holders.
These stakeholders can expect to see benefits as highlighted below: Reserve Managers will see two new benefits to providing liquidity for the network. The first of these benefits will be incentives for providing reserves. Once Katalyst is implemented part of the fees collected will go to the reserve managers as an incentive for providing liquidity.
This mechanism is similar to rebates in traditional finance, and is expected to drive the creation of additional reserves and market making, which in turn will lead to greater liquidity and platform reach.
Katalyst will also do away with the need for reserve managers to maintain a KNC balance for use as network fees. Instead fees will be automatically collected and used as incentives or burned as appropriate. This should remove a great deal of friction for reserves to connect with Kyber without affecting the competitive exchange rates that takers in the system enjoy. dApp Integrators will now be able to set their own spread, which will give them full control over their own business model. This means the current fee sharing program that shares 30% of the 0.25% fee with dApp developers will go away and developers will determine their own spread. It’s believed this will increase dApp development within Kyber as developers will now be in control of fees.
KNC Holders, often thought of as the core of the Kyber Network, will be able to take advantage of a new staking mechanism that will allow them to receive a portion of network fees by staking their KNC and participating in the KyberDAO.

2.7 COMING KYBERDAO

With the implementation of the Katalyst protocol the KNC holders will be put right at the heart of Kyber. Holders of KNC tokens will now have a critical role to play in determining the future economic flow of the network, including its incentive systems.
The primary way this will be achieved is through KyberDAO, a way in which on-chain and off-chain governance will align to streamline cooperation between the Kyber team, KNC holders, and market participants.
The Kyber Network team has identified 3 key areas of consideration for the KyberDAO: 1. Broad representation, transparent governance and network stability 2. Strong incentives for KNC holders to maintain their stake and be highly involved in governance 3. Maximizing participation with a wide range of options for voting delegation
Interaction between KNC Holders & Kyber
This means KNC holders have been empowered to determine the network fee and how to allocate the fees to ensure maximum network growth. KNC holders will now have three fee allocation options to vote on: - Voting Rewards: Immediate value creation. Holders who stake and participate in the KyberDAO get their share of the fees designated for rewards. - Burning: Long term value accrual. The decreasing supply of KNC will improve the token appreciation over time and benefit those who did not participate. - Reserve Incentives:Value creation via network growth. By rewarding Kyber reserve managers based on their performance, it helps to drive greater volume, value, and network fees.

2.8 TRANSPARENCY AND STABILITY

The design of the KyberDAO is meant to allow for the greatest network stability, as well as maximum transparency and the ability to quickly recover in emergency situations. Initally the Kyber team will remain as maintainers of the KyberDAO. The system is being developed to be as verifiable as possible, while still maintaining maximum transparency regarding the role of the maintainer in the DAO.
Part of this transparency means that all data and processes are stored on-chain if feasible. Voting regarding network fees and allocations will be done on-chain and will be immutable. In situations where on-chain storage or execution is not feasible there will be a set of off-chain governance processes developed to ensure all decisions are followed through on.

2.9 KNC STAKING AND DELEGATION

Staking will be a new addition and both staking and voting will be done in fixed periods of times called “epochs”. These epochs will be measured in Ethereum block times, and each KyberDAO epoch will last roughly 2 weeks.
This is a relatively rapid epoch and it is beneficial in that it gives more rapid DAO conclusion and decision-making, while also conferring faster reward distribution. On the downside it means there needs to be a new voting campaign every two weeks, which requires more frequent participation from KNC stakeholders, as well as more work from the Kyber team.
Delegation will be part of the protocol, allowing stakers to delegate their voting rights to third-party pools or other entities. The pools receiving the delegation rights will be free to determine their own fee structure and voting decisions. Because the pools will share in rewards, and because their voting decisions will be clearly visible on-chain, it is expected that they will continue to work to the benefit of the network.

3. TRADING

After the September 2017 ICO, KNC settled into a trading price that hovered around $1.00 (decreasing in BTC value) until December. The token has followed the trend of most other altcoins — rising in price through December and sharply declining toward the beginning of January 2018.
The KNC price fell throughout all of 2018 with one exception during April. From April 6th to April 28th, the price rose over 200 percent. This run-up coincided with a blog post outlining plans to bring Bitcoin to the Ethereum blockchain. Since then, however, the price has steadily fallen, currently resting on what looks like a $0.15 (~0.000045 BTC) floor.
With the number of partners using the Kyber Network, the price may rise as they begin to fully use the network. The development team has consistently hit the milestones they’ve set out to achieve, so make note of any release announcements on the horizon.

4. COMPETITION

The 0x project is the biggest competitor to Kyber Network. Both teams are attempting to enter the decentralized exchange market. The primary difference between the two is that Kyber performs the entire exchange process on-chain while 0x keeps the order book and matching off-chain.
As a crypto swap exchange, the platform also competes with ShapeShift and Changelly.

What the minimun amount of nodes to run a blog on IPFS-Cluster?

Hi guys
I'm looking for setting up an ipfs cluster on aws ec2 to build a descentralized version of my blog. But I just dont know the minimum amounts of nodes( ec2 instances ) to run my blog. I read something related to the Raft algorithm or something like that and in that post the author said ' the minimum amount of nodes is above 3' to safe the permanently of the data in case of any node fall.
Another thought, A few minute ago I discover that you can get a decentralized domain names like ones delivered by ethereum name services( ENS ). What other blockchain project are doing the same? I mean , it's really a awesome moment to learn about this stuffs!!

7 legendary and most successful ICOs in cryptocurrency history

Let's find out which companies have succeeded with the initial token offering (ICO), raised as much money as planned, and fulfilled their promises to investors.
Every year, tens of billions of dollars are invested in tokens. The importance of this issue increased after Pavel Durov's TON ICO was actually outlawed by an American court. The uncertain status of cryptocurrency Libra from Mark Zuckerberg also added concern to crypto investors. So was there at least one successful ICO?
Yes, It was, and not just one. Let's arrange these cases in chronological order.

1. Mastercoin — 2013

You could hear about this cryptocurrency under the name “Omni”. This was the first registered ICO (we could call it the grandfather of ICO).
On July 31, 2013, a special fund was created for investment. About 500 people transferred 5,000 BTC into this fund. In 2013, this amount was $ 500 thousand. For the first time in the history of cryptocurrencies, the creators promised anyone who buys a Mastercoin an opportunity to use it as an investment tool. After the launch of the system, the value of coins was supposed to increase, and the holder could sell it freely.
Was this plan implemented? Yes, it was. In less than a year, Mastercoin already ranked seventh in the cryptocurrency market.
The renaming of Mastercoin to Omni took place in 2015. Now it’s not just a coin, but a Bitcoin-based platform, on which the one can trade digital assets, and also create them.

2. Ethereum (ETH) — 2014

One of the prime examples of a successful token placement campaign. In just 12 hours, it raised $2.3 million. And in September 2014 it raised $18.4 million in total.
This is how it all happened. A unique feature of the platform at that time was the smart contract system. A key feature of Ethereum is to provide a basis for other projects to build and develop their technologies.
Information about the total number of available tokens was not disclosed, but 60 million tokens were successfully sold. Global fundraising goals were not limited to anything.
Was the ICO successful and have all the promises been fulfilled? Definitely. To this day, this ICO is considered one of the most successful in history and an example of worthy crowdfunding. Ethereum lives, develops and is second in terms of capitalization after BTC. On its basis, new platforms are being built.

3. EOS Project (EOS) from block.one — 2017

This project raised $185 million for the development and implementation of a new blockchain architecture that automates financial processes and evaluates transaction parameters. It helps to create high-quality business applications.

4. Status (SNT) — 2017

Another example of brilliant success. This blockchain messenger and mobile operating system (built on Etehreum technologies) were developed to work with decentralized mobile applications. Status raised over $100 million on the first day. Promises are fulfilled, applications work and allow to use encrypted messages, smart contracts, payments, chatbots, and operate with any available ICOs. There's also a built-in currency exchange. The system allows you to store your crypto assets in a special Status wallet.

5. Bancor (BNT) — 2017

In 2016-2017 there was a real ICO boom. The Bancor project's shown even faster fundraising than its predecessors. In just 3 hours, $140 million tokens were bought. In total, BNT was sold in the amount of $153 million. Bancor's goal is to increase the liquidity of ERC-20 tokens (Etehereum) and make BNT actually reserve currency. It doesn't require any exchanges and offers its owners an investment basket. Bancor works with smart contracts and allows you to issue your tokens and link any tokens to a plastic card.
However, you can only call it successful with some limitations. It's restricted in the USA, and there are questions about the tokens that rotate on this platform. However, outside of America, people make BNT transactions, which means that it can’t be called a failure (Gram's also banned in the USA yet).

6. Tezos (XTZ) — 2017

For the first 5 days, the Swiss company Tezos raised $137 million through ICO. The total amount of token sale was about $230 million. This placement is rightfully considered one of the most successful in crypto history.
The project offers a flexible alternative system of smart contracts and is opposed to the Ethereum system on which many companies build their networks.

7. Filecoin (FIL) — 2017

In 2014, Protocol Labs launched this system as part of a secure and reliable data storage program based on IPFS protocol (InterPlanetary File System). The regulated ICO of 2017 showed excellent results with the requested $40 million. It was possible to raise $257 million, i.e. almost 6.5 times more.
After the boom in 2016-2017, there were many successful ICOs, but these seven placements were most memorable.

Where you can see all ICOs yourself

There're several useful resources that allow you to get information about the active and upcoming placement of tokens (without investment recommendations) and an archive of past ICOs. These are ICOMARKS and ICODROPS platforms.

7 legendary and most successful ICOs in cryptocurrency history

Let's find out which companies have succeeded with the initial token offering (ICO), raised as much money as planned, and fulfilled their promises to investors.
Every year, tens of billions of dollars are invested in tokens. The importance of this issue increased after Pavel Durov's TON ICO was actually outlawed by an American court. The uncertain status of cryptocurrency Libra from Mark Zuckerberg also added concern to crypto investors. So was there at least one successful ICO?
Yes, It was, and not just one. Let's arrange these cases in chronological order.

1. Mastercoin — 2013

You could hear about this cryptocurrency under the name “Omni”. This was the first registered ICO (we could call it the grandfather of ICO).
On July 31, 2013, a special fund was created for investment. About 500 people transferred 5,000 BTC into this fund. In 2013, this amount was $ 500 thousand. For the first time in the history of cryptocurrencies, the creators promised anyone who buys a Mastercoin an opportunity to use it as an investment tool. After the launch of the system, the value of coins was supposed to increase, and the holder could sell it freely.
Was this plan implemented? Yes, it was. In less than a year, Mastercoin already ranked seventh in the cryptocurrency market.
The renaming of Mastercoin to Omni took place in 2015. Now it’s not just a coin, but a Bitcoin-based platform, on which the one can trade digital assets, and also create them.

2. Ethereum (ETH) — 2014

One of the prime examples of a successful token placement campaign. In just 12 hours, it raised $2.3 million. And in September 2014 it raised $18.4 million in total.
This is how it all happened. A unique feature of the platform at that time was the smart contract system. A key feature of Ethereum is to provide a basis for other projects to build and develop their technologies.
Information about the total number of available tokens was not disclosed, but 60 million tokens were successfully sold. Global fundraising goals were not limited to anything.
Was the ICO successful and have all the promises been fulfilled? Definitely. To this day, this ICO is considered one of the most successful in history and an example of worthy crowdfunding. Ethereum lives, develops and is second in terms of capitalization after BTC. On its basis, new platforms are being built.

3. EOS Project (EOS) from block.one — 2017

This project raised $185 million for the development and implementation of a new blockchain architecture that automates financial processes and evaluates transaction parameters. It helps to create high-quality business applications.

4. Status (SNT) — 2017

Another example of brilliant success. This blockchain messenger and mobile operating system (built on Etehreum technologies) were developed to work with decentralized mobile applications. Status raised over $100 million on the first day. Promises are fulfilled, applications work and allow to use encrypted messages, smart contracts, payments, chatbots, and operate with any available ICOs. There's also a built-in currency exchange. The system allows you to store your crypto assets in a special Status wallet.

5. Bancor (BNT) — 2017

In 2016-2017 there was a real ICO boom. The Bancor project's shown even faster fundraising than its predecessors. In just 3 hours, $140 million tokens were bought. In total, BNT was sold in the amount of $153 million. Bancor's goal is to increase the liquidity of ERC-20 tokens (Etehereum) and make BNT actually reserve currency. It doesn't require any exchanges and offers its owners an investment basket. Bancor works with smart contracts and allows you to issue your tokens and link any tokens to a plastic card.
However, you can only call it successful with some limitations. It's restricted in the USA, and there are questions about the tokens that rotate on this platform.

Sharder (SS) | Coin Review | Blockfyre

Overview
The Sharder team describes their implementation of the Sharder protocol as a “cross-chain distributed storage mechanism.” In other words, Sharder aims to decentralize the cloud data storage system. It does this by creating an efficient, decentralized, and secure sharing network where users can share their storage space for Sharder tokens. Actually, it’s much more than that, but we will get into that later. They are not the only blockchain project in this space, but they came up with an exciting technology and a huge range of features. The team here is trying to do a lot, which might separate them from their competitors in the long run.
What Problem does Sharder solve?
Sharder aims to solve a number of issues, related to the exploding growth of data in our connected, data-driven world. There are two big problems with current data storage solutions in terms of capacity and utilization. First of all, the growth of data is outpacing the growth of storage capacity. We are in a market where the demand for storage is far from being satisfied. This growth is not going to end soon, according to IBM we create 2.5 quintillion bytes of data a day, and this number is likely going to double over the next 3–5 years. This exponential growth calls for a new decentralized solution, which could offer more efficiency, less friction and a new way to handle, store and even monetize data and therefore data storage capacity.
The second big issue is the inefficient use of said existing storage capacity. There is a significant amount of storage space belonging to individuals and corporations that lie unused and is therefore wasted. Sharder picked up the idea of a sharing economy approach, where users can rent out unused storage space, to other parties in the network, who need more capacity. Users who rent out their idle storage space on Sharder’s network will be rewarded with Sharder tokens.
According to the Sharder whitepaper, there are many additional pain points in today’s centralized data storage market including lack of encryption, proneness to data breach and abuse, mutability, impermanence, and high costs. The Sharder ecosystem aims to solve these issues through its blockchain based data storage solution. With its initiative cross-chain architecture, it optimizes the verification, consensus, and credential mechanisms, contribution quantification, encryption technology, data sharing, file system and dramatically improves the security, availability, and flexibility of the network. Alongside that, Sharder allows its users to perform private file transactions on the network. Wich in a more and more privacy-focused world could play a significant role in the near future.
Product and Vision
The Sharder Protocol is the central part of the Sharder ecosystem. It is a cross-chain distributed storage protocol based on blockchain 3.0. Cross chain-means, that it could be deployed on all public chains (such as Qtum and Ethereum), storage networks (such as IPFS and Aliyun) and personal nodes. Since Sharder is a protocol, DApps can be developed on top of it. This allows for Sharder to not just be a “Dropbox on the Blockchain.” Instead, the network is more than just a decentralized storage solution. The team found ways to allow utilization and monetization of data in many different ways, which separates them from other players in their industry. We’ve already talked about the sharing economy aspect, let’s look into Shaders main functions as a protocol, which, through Dapp development, adds versatility, and therefore allows for limitless implementations of the Sharder Protocol.
Dapps
The ability to build Dapps on the platform makes it highly interesting for different industries to utilize the network, customized to their individual requirements. Four of these applications are already deployed to the system:
SignEase
SignEase is a data storage, certification, and security platform that allows for P2P finance, small loans, consumer finance, e-commerce, ERP system, etc. SignEase stores data such as the e-contracts, payment vouchers, investment records in Sharder Network and It offers a data storage and validation SaaS.
Sharder Matrix
An application that stores personal data and allow for the constant accumulation of this data from individuals or businesses, as the data accumulates, a personal Sharder Matrix will take shape. Sharder Matrix does not only ensures privacy but also provides convenient usage and management.
Sharder Brain
Sharder is making use of developments in the field of artificial intelligence, smart devices, internet of things here. Sharder Brain is an intelligent data service for individuals and enterprises. It could serve in data security, data distribution adjustment, data analysis, data search, data alerts, etc.
One Fair
Simply put, One Fair is a transparent, open-source, peer-to-peer marketplace for data. The tradable items include storage space, digital assets, verified data, valuable information, etc. For instance, one could sell his/her own biological data to medical or research institutes.
ISLAND
Sharder is being paid by ISLAND to develop this app. Know anyone who has sensitive photos, videos or documents on their phone that they want access to but don’t trust who has access to their phone’s gallery, icloud or google cloud? ISLAND is the solution.The app will compete with other hidden / secret photo apps but goes 10 steps further, you can store data behind the app, so its not in your gallery but still uses your phone storage for instant access. Or you can upload / download to Sharder Network so no records are on your phone until you retrieve it with Sharder Chain.
Island will be a blockchain storage app for your mobile phone to store sensitive photos, videos, documents and notes without utilizing your phones storage. It is an ideal solution for anyone concerned about who has access to their phone / cloud storage. The App which will be released on the App Store and Google Play. ISLAND will require SS to pay for storage costs and upload bandwidth.
It is forecast, at current market rates that ISLAND will require to purchase 66 SS per user / per month. They are forecasting 100,000 users by March 2021. 66 SS * 100,000 Users = 6,6 million $SS / per month!
Yet another source of constant buy pressure for the SS token like with Signease.
Blockdrop
Blockdrop is a new app they are developing as a blockchain alternative to the world-famous DropBox. As you probably know, China has always been agressive in promoting their own products over western competitors. That’s why in China you have Weibo being much larger than Twitter, even though it’s essentialy the same product. This makes me think Blockdrop might really take off there. More info on this app will come in Q4.
Privacy and system architecture
Private data storage has an enormous amount of use cases for various industries, such as pharma, healthcare, finance and many more. Sharder-UTXO, zSNARK, and Sharder-Keypair models ensure that data could not be accessed without credentials. Absolute ownership and privacy is guaranteed. Sharder also employs offline data sharing and data encryption to ensure that the network remains private.
Sharder Pools are another interesting aspect of the Sharder Protocol. We’ve already talked about the cross chain ability of Sharder, now each chain on which Sharder is deployed builds their own Sharder Pool. In the whitepaper, these pools are referred to as “mini-networks”, which all run multiple nodes. In our example from earlier, we would have a Qtum-Pool and an Ethereum-Pool. Once Sharder Protocol is deployed, the public chain and storage network becomes the very first Sharder Pool, this pool (Sharder-Pool0), is the cornerstone of Sharder Network, all future pools derive from this one. Therefore, all nodes can be affiliated to the Sharder Pool but can also run separately if they chose too. If they do so, they will remain an isolated network, like a private chain, forming a private cloud storage network. This offers several possibilities when it comes to privacy and is a logical step when we consider businesses as the primary target market for Sharder.
Consensus algorithm and mining
The Sharder team believes that proof of work and the related “hardware arms race” is an inefficient, expensive and wasteful process for the creation of new blocks. Because of that, they developed a new mechanism called the Consensus Block Generation. This method allows each Sharder Pool to have its own internal consensus and Transaction-Bundle, which is a block that contains many transaction records. Ultimately the Full Node will generate Sharder blocks and broadcast it to the Sharder Network, with each Transaction-Bundle. To bundle a Sharder block, the node has to connect to the Sharder Chain (Sharder-Pool0). The average time for block generation is 7 minutes in the Sharder testnet (fastest is 10 seconds per block). In the future, the block generation time will be adjustable in accordance with the task being performed.
Team
With 20 active team members listed on their website, the Sharder team is reasonably large. Lets take a look at some of their key roles. Sharder’s CEO and founder Ben Xiong has over 15 years of experience in the digital domain, programming and software development. In terms of his past work experience, Ben has served as the Lead Architect of Seachange, Chief Architect of Yiji Pay, Co-founder and CTO of Taogushen,com, Founder of Conch Chain.
Their COO Jeffrey Zhu has over eight years of experience in domains such as programming, management, operating and entrepreneurship. He holds a B.S. degree in computer science and has been involved in a companies called Beiming and Chain Renaissance Capital, as a co-founder.
Lastly, Rick Wang is the CMO of Sharder. He has over six years of experience in marketing, channel development, and entrepreneurship. His previous work experience includes Marketing Director of Huangcheng Technology Co., Ltd. and General Manager of Zebra Environment Technology Co., Ltd.
The advisory board has some interesting names on it including Aaron Zhang, who was previously leading the strategy department at Houbi exchange. All in all, the team seems very balanced in terms of backgrounds, there is no lack in either direction, whether it’s technical development or business focus. Sharder has multiple programmers and software architects with 10+ years of experience in blockchain and software development. Furthermore, the marketing team has experience in various domains, where they led different successful projects in the past. This is not yet an all-star Team, but I would definitely view them as a strong point for the project.
Tokenomics: What is the SS Token?
Sharder (SS) is the cryptocurrency embedded in Sharder Protocol. It acts as the incentive in the Sharder ecosystem to reward nodes that contribute to the network and penalize malicious nodes. Additionally, SS works as the anchoring token in Sharder’s multi-chain architecture. There are four main contributing parties in the system, who will be rewarded in SS: block generators (similar to miners in blockchain networks, miners need to run a node to store block information and process transactions), watchers (Observes the entire network state, checks the security, and fixes existing or potential loopholes), provers (converts data into digital assets and adds public credibility to it) and storers (provides storage capacity for data). These roles are building the foundation for the Sharder ecosystem.
The team is releasing its own hardware (dedicated storage hubs, sharder boxes). From here, they will enable users to earn SS by providing the network with storage, and by mining. They have partnered with a Chinese hardware manufacturer to ensure the production of around 500 Sharder Hubs in the first batch. They will start shipping in April 2019.
The maximum supply is capped at 500.000.000 SS. The current total supply is 350.000.000 SS, of which 283.282.765 SS are currently in circulation. The team holds 10% of the supply as an incentive for the team members and developers. The lock-up period for the coins is three years, and 1/3 of the coins will be unlocked per year.
Growth potential and Roadmap
Let’s start this section by looking into the whitepaper and roadmap. The technical whitepaper is 24 pages long, which is a standard for a project of Sharder’s size and scope. That said, it is very professional in its format, and mostly clear about the underlying technology, which is not always the case for Chinese projects. The whitepaper focuses on a wide range of problems with current data storage models and the solutions Sharder is offering, this could be perceived as too big of a challenge by investors, because some component could need some more in-depth explanation. While it is clear and concise, the white paper is not written in exceptionally well English, which is not a problem in this case. No doubt these grammatical errors will be revised somewhere down the line.
Some of the terminologies Sharder uses to describe components of the network may be overwhelming for some. With all of the features, Sharder is looking to implement, investors should keep tabs on the development progress of this project, especially with an ambitious roadmap like Sharder has set for themselves.
The full history of Sharder is available from early 2018. The roadmap ends in Q4 2019, which isn’t uncommon for a project in this early stage. The roadmap is packed with updates and improvements, the biggest upcoming events are their mainnet launch, which is scheduled for Q3 2019 and the beginning of the testnet testing, starting in April 2019. At this point, I also have to give them credit for continually providing very detailed updates through their blog.
In terms of potential adoption, Sharder has been able to build partnerships with various companies that could implement Sharder’s technology in the future. These partnerships include ZBJ.com, Yijipay, Seachange, and more. In fact, over 100 businesses have signed up to test their SignEase service for handling sensitive data and SignEase currently as over 500 registered users. The Team is working with relevant government departments in China and are part of an alliance for the development of the blockchain industry in the city of Chongqing.
I believe there is no doubt about the potential overall market for Sharders products. Like I’ve mentioned in the introduction, the amount of data we produce is growing at an immensely fast rate, and the value of this data is increasing too. Therefore Sharder is addressing a very sustainable field, which is ripe for innovative solutions to store, manage and monetize data in a new way.
Big markets naturally attract competition; a number of projects have been popping up over the past year. Sia, Storj, Dadi, and others are all fighting for their share in this space, with their own take on the decentralized storage solution. I don’t have huge concerns here, Sharders platform approach and unique features could make it stand out from the rest.
Conclusion
From an investor standpoint, Sharder is a high-risk/high reward opportunity. If they do pull through their ideas and implement their technology on a broad range, I believe Sharder can find itself in the Top 100 easily.
One issue they will have to overcome is dealing with fluctuating prices of storage capacity. Business clients will need stable costs, which will be hard to maintain when the networks grows, and SS rises in value, as the market will decide the coin’s value. To overcome this problem, the team is encouraging users to pay for services in SS, which could at least decrease volatility. Additionally, they are will also be safeguarding the storage pricing via smart contract, meaning, the pricing will remain the same for the duration of contract validity.
If the Sharder team is able to reach all their milestones and adequately market themselves to new clients, partners and potential miners, I expect to see them becoming a leader in their space. It is necessary for them to I develop additional partnerships with private industry and government and enhance their marketing capabilities and community building. They have taken some steps in the right direction, with their community whitepaper and more aggressive marketing approach, but still, there is no point in developing a great product if no one knows about its existence. Looking through their blog updates, it becomes clear, that the team is very busy in this regard.
SS scored 56 out of 76 Points in our evaluation program.
📊 You can buy and sell SS on HotBit & Uniswap
👥 I have been in contact with one of their Ambassadors (John Vic) who provided me with further information about the project.

Ethereum on ARM. Ethereum 1.0/2.0 ecosystem installation on Ubuntu server 64bit for Raspberry Pi 4 (step by step guide) - Join ETH 2.0 testnets through Prysm / Lighthouse clients on RPi4. Memory enhancements

Ethereum on ARM is a project that provides custom Linux images for Raspberry Pi 4 (Ethereum on ARM32 repo [1]),NanoPC-T4 [2] and RockPro64 [3] boards (Ethereum on ARM64 repo [4]) that run Geth or Parity Ethereum clients as a boot service and automatically turns these ARM devices into a full Ethereum node. The images include other components of the Ethereum ecosystem such as Status.im, Raiden, IPFS, Swarm and Vipnode as well as initial support for ETH 2.0 clients.
Images take care of all necessary steps, from setting up the environment and formatting the SSD disk to installing and running the Ethereum software as well as synchronizing the blockchain.
All you need to do is flash the MicroSD card, plug an ethernet cable, connect the SSD disk and power on the device.

The what and why of a 64 bits Raspberry Pi 4 image, 32 vs 64 bits

Following my last post [5], there are a couple of ongoing issues with the Raspberry Pi 4 that prevent Ethereum software to run as expected.
Given the massive adoption of the Raspberry Pi device, a 64 bit image would allow users to run full nodes without RAM issues and join ETH 2.0 testnets. While Raspbian certainly has a plan to migrate the OS to a full 64bit image there is not an official statement or roadmap about this. In the meanwhile, as ETH 2.0 phase 0 is around the corner, it is worth to try to find a viable alternative to run a 64bit OS on the Pi.

Installation of an Ubuntu server 64bit image for the Raspberry Pi 4 with Ethereum 1.0/2.0 ecosystem. Step by step guide.

James Chambers released an 18.04 Ubuntu server 64 bit image for the Raspberry Pi 4 using the latest Raspbian and the official 19.04 Ubuntu images [7] (amazing job, by the way). Obviously, this is work in progress, has no official support and is not considered stable. But it runs reasonably well and, as stated before, a native 64 bits image opens the door for joining the ETH 2.0 public test networks for Raspberry Pi 4 users as well as solving the 32 bits “out of memory” RAM issues. So it is worth it to give it a try.
DISCLAIMER: As this is a handcrafted image the installation it is not Plug and Play like the stable Ethereum on ARM images so you will need some Linux skills here. I tried to make the process as straightforward as possible though (it should take just 10-15 minutes).
The installation procedure has two main steps.
  1. Install Raspbian, needed to update the raspberry pi 4 to the latest (unstable) available firmware and format the USB disk
  2. Install Ubuntu 64 bits, to have a system with a 64 bit kernel and user space
INSTALL RASPBIAN
DISCLAIMER: In this step we’re going to update the firmware to the latest unstable version. It can break things and even make the Raspberry Pi unbootable (not likely at all, but possible), so, be careful here.
Prerequisites: Make sure you have the USB disk attached (blue USB port) and the network connected to the RPi 4.
1. In your Linux desktop: Open a terminal, download the Raspbian image, insert the MicroSD and flash it:
wget https://downloads.raspberrypi.org/raspbian_lite/images/raspbian_lite-2019-09-30/2019-09-26-raspbian-buster-lite.zip unzip 2019-09-26-raspbian-buster-lite.zip sudo dd bs=1M if=2019-09-26-raspbian-buster-lite.img of=/dev/mmcblk0 conv=fdatasync status=progress 
2. In your Raspberry Pi 4: Insert the MicroSD, boot up and log in (user:pi password:raspberry). Keep in mind that ssh is not enabled by default so you will need a monitoTV and a keyboard. Download Ethereum on ARM setup script to update the Firmware and format the USB 3 disk.
wget https://github.com/diglos/pi-gen/raw/ethraspbian2.0/stage2/04-ethereum/files/ethonarm-rpi4-ubuntu64bit-setup.sh sudo sh ethonarm-rpi4-ubuntu64bit-setup.sh 
  1. Power off the Raspberry and extract the MicroSD again.
INSTALL UBUNTU SERVER
1. In your Linux desktop: Insert the MicroSD. Open a terminal, download James Chambers Ubuntu image and flash it:
wget https://github.com/TheRemote/Ubuntu-Server-raspi4-unofficial/releases/download/v26/ubuntu-18.04.3-preinstalled-server-arm64+raspi4.img.xz xz -d ubuntu-18.04.3-preinstalled-server-arm64+raspi4.img.xz sudo dd bs=1M if=ubuntu-18.04.3-preinstalled-server-arm64+raspi4.img of=/dev/mmcblk0 conv=fdatasync status=progress 
2. In your Raspberry Pi 4: Insert the MicroSD, boot up and log in (user:ubuntu password:ubuntu). You will be prompted to change the password so you’ll need to log in twice. SSH is enabled by default.
3. RUN ETHEREUM ON ARM INSTALLATION SCRIPT
Download the install script and run it:
wget https://github.com/diglos/pi-gen/raw/ethraspbian2.0/stage2/04-ethereum/files/ethonarm-rpi4-ubuntu64bit-install.sh sudo sh ethonarm-rpi4-ubuntu64bit-install.sh 
4. Reboot the Pi and you will be running a full ETH 1.0 node / ETH 2.0 test client on a native Ubuntu server 64bit OS. Keep in mind that Geth and Status run by default so if you don’t want to run a full Ethereum node or a Status node you need to stop and disable them by running:

ETH 2.0 testnets on Raspberry Pi 4

Prysm and Lighthouse latest versions are now available so you can join/test the ETH 2.0 implementations with your Raspberry Pi 4:
Prysm 0.3.1: Take into account that at the time of writing this post, the sync process is very slow, see [8]. The packages provides 2 binaries: beacon-chain and validator.
Follow the instructions [9] to join the test network. Basically, get the Goerli ETH (no real value), set the validator password and run both clients. Once you have done all required steps and make sure everything goes as expected you can edit the file etc/ethereum/prysm-validator.conf and define the password previously set in order to run both clients as a systemd service:
sudo systemctl start prysm-beacon sudo systemctl start prysm-validator 
For more information about joining the Prysm testnet check the official docs [10]
Lighthouse 0.1.1: Currently provided as a single binary (no systemd service): lighthouse.
Lighthouse team is doing a fantastic progress as well [11] so expect news regarding the testnet soon. You can check their official documentation here [12]
ETH 2.0 is under heavy development right now [13] so I will be providing clients updates as soon as they are released. You can update the Eth 2.0 clients anytime by running:
sudo apt-get update && sudo apt-get install prysm-beacon prysm-validator lighthouse 
If you have the time and the skills to install the image and join the ETH 2.0 testnets, please do. It is a very valuable feedback for all teams involved, particularly at this early stage.

Memory and cache tweaks

Working on enabling swap memory for the Ubuntu 64bit image I realized that Armbian developers put a lot of work trying to maximize the memory usage on these kind of boards [14]. This is something really important with such a limited resource as it needs to be as much efficient as possible (try to avoid "out of RAM" crashes and don’t waste too much CPU as well as disk throughput in swap tasks).
Particularly, I focused on 2 tasks:
I encourage users to test these parameters and try to find the best combination in order to achieve better sync results. I'm currently running several test on the Rpi4 in order to find an optimal setup.
On top of this, I also ran some tests with the NanoPC (in this case, lowering a little the default Geth cache to 768) that resulted on Sync time improvements:
NanoPC-T4 Fast Sync data

A new version of the Streamr Marketplace, Uniswap exchange functionality, Network WebRTC implementation, multi-tracker support testing, and more. Follow the latest tech news in the Streamr dev update.

Dev Update April 2020


https://preview.redd.it/zs18kanjpqz41.png?width=1600&format=png&auto=webp&s=486243fc6649b3c75c1453824cc894aac3c8f621
Welcome to the Streamr dev team update for April 2020. A lot has happened in the last month, so let’s kick off. Streamr has:
  • Released a new version of Marketplace
  • Integrated Uniswap exchange functionality
  • Tested multi-tracker support for the Network
  • Continued WebRTC implementation for the Network
A quick editor’s note: we are adding a new section to our monthly dev update titled Deprecations and breaking changes. As you might have guessed, it is to keep all developers building on top of Streamr ecosystem informed about upcoming deprecations (features or components not supported anymore) and breaking changes (alteration in functions, APIs, SDKs and more, that require a code update from the developer side).
The newly deployed Marketplace contains a suite of analytics that users can explore on published Data Union products — number of users belonging to a particular Data Union, aggregated earning, estimated earning potential per user and more. Here you can see the example for Swash, published on the Marketplace. Note that Swash is still in its beta phase and the Data Union Product has been migrated to a newer version of a Data Union smart contract, so the current metrics don’t show the full picture.
Additionally, we also deployed a long-awaited Uniswap integration on the Marketplace. Thanks to this decentralized exchange (DEX), data buyers now can now use either ETH or DAI to pay for a subscription, in addition to DATA coins. This is an important milestone because it simplifies the purchase process, which had caused some friction for new users.

https://preview.redd.it/nk4dbngopqz41.png?width=1217&format=png&auto=webp&s=8a06698e8e316fd9957efd7df9ab815cc42f9256
Recently, the Network developer team finished testing a multi-tracker implementation. For any readers who are not yet familiar with the role a tracker plays in the Network, our core engineer Eric Andrews wrote the following in his recent blog post on the Network workshop:
An important part of the Network is how nodes get to know about each other so they can form connections. This is often referred to as ‘peer discovery’. In a centralized system, you’ll often have a predetermined list of addresses to connect to, but in a distributed system, where nodes come and go, you need a more dynamic approach. There are two main approaches to solving this problem: trackerless and tracker-based. In the tracker-based approach, we have special peers called trackers whose job it is to facilitate the discovery of nodes. They keep track of all the nodes that they have been in contact with, and every time a node needs to join a stream’s topology, they will ask the tracker for peers to connect to.


A representation of the physical links of the underlay network
Now that we have finished testing the tracker model, the next step is to try to create an on-chain tracker registry and let Network nodes read the tracker list directly from there. This can be accomplished via a smart contract on the Ethereum network, so that this whole process of peer discovery can be handled in a decentralized way. In future, richer features could be deployed for the tracker registry, such as reputation management and staking to lower possibility of misbehavior or network attacks. The team made further progress on the Network side with the gradual implementation of WebRTC for the nodes. We recently ran an experiment, running over 70 WebRTC nodes on Linux local environment, and results were promising. That gave us additional assurance to proceed with the full implementation.
Regarding the Data Union development progress, we noticed there have been some performance issues and potential bugs on the balance calculation, due to Data Union server restarting. We sincerely apologize for the inconvenience caused, and we are working to improve the Data Union architecture to guarantee higher stability before the official public launch later this year.

Deprecations and breaking changes

This section summarizes all deprecated features and planned breaking changes.
  • June 1st, 2020: Support for Control Layer protocol version 0 and Message Layer protocol versions 28 and 29 will cease. This affects users with outdated client libraries or self-made integrations dating back more than a year. The deprecated protocol versions were used in JS client libraries 0.x and 1.x , as well as Java client versions 0.x . Users are advised to upgrade to newest libraries and protocol versions.
  • June 1st, 2020: Currently, resources on Streamr (such as streams, canvases, etc.) have three permission levels: read , write , and share . This will change to a more granular scheme to describe the exact actions allowed on a resource by a user. They are resource-specific, such as stream_publish and stream_subscribe . The upgrade takes place on or around the above date. This may break functionality for a small number of users who are programmatically managing resource permissions via the API. Updated API docs and client libraries will be made available around the time of the change.
  • Further away (date TBD): Authenticating with API keys will be deprecated. As part of our progress towards decentralization, we will eventually end support for authenticating based on centralized secrets. Integrations to the API should authenticate with the Ethereum key-based challenge-response protocol instead, which is supported by the JS and Java libraries. At a later date (TBD), support for API keys will be dropped. Instructions for upgrading from API keys to Ethereum keys will be posted well in advance.
  • Further away (date TBD): Publishing unsigned data will be deprecated. Unsigned data on the network is not compatible with the goal of decentralization, because untrusted nodes could easily tamper data that is not signed. As the Streamr Network will be ready to start decentralizing at the next major milestone (Brubeck), support for unsigned data will be ceased prior to reaching that. Users should upgrade old client library versions to newer versions that support data signing, and use Ethereum key-based authentication (see above), which enables data signing by default.
Below is the more detailed breakdown of the month’s developer tasks. If you’re a dev interested in the Streamr stack or have some integration ideas, you can join our community-run dev forum here.
As always, thanks for reading.

Network

  • Multi-tracker support is done. Now working on reading tracker list from smart contract
  • Moving forward with WebRTC implementation after local environment testing
  • Continuing fixes for Cassandra storage and long resend issues.

Data Unions

  • Some Java client issues were affecting Data Union joins, but these should all be fixed now
  • Improved Data Union Server monitoring. Join process is being continuously monitored in production
  • Team started implementing storing state snapshots on IPFS
  • JS client bugs fixes to solve problems with joins in Data Union server
  • Data Union developer docs are being finalised

Core app (Engine, Editor, Marketplace, Website)

  • Implementing UI for managing buyer whitelist for Marketplace
  • New Marketplace version has been deployed with Data Union metrics
  • New product views and Uniswap purchase flow are now live.
