    DutchX has peaked at $1m daily trading volume yesterday and generated ~$40k in fees since Februray - now we are giving full ownership to the community. Update from the dxDAO.

    Posted: 19 Jun 2019 07:34 AM PDT

    Three weeks ago we announced the dxDAO experiment here.

    Now I want to give an update where we are at. As a recap - the dxDAO is a governance experiment open for anyone to join. It is a general purpose DAO that can be seen as a startup with many hundred co-founders. As a starting point, we (Gnosis) are basically donating the dutchX (a trading protocol/DEX) to it.

    There are 9 more days during those anyone can participate here. Until this point, 319 people/addresses are participating. In total, they have locked ~$10M worth of ERC20 tokens and $6.5M worth of ETH for voting rights. Full statistics here.

    In detail, the 4 ways to participate:

    1. Lock ETHLock ETH for 30 days (you will fully get it back). The more you lock the more you get out of this pool. In total 8% of voting rights are given to ETH lockers. Currently, $6.5M are locked. That means that you need to lock $8k worth of ETH to get 0.01% of the voting power of the DAO.
    2. Lock ERC 20 tokensSame mechanism as ETH lock but with ERC20 tokens. Here is the list of ERC20 tokens that are eligible for locking. 30% of the voting power is given to this category. Currently, ~10M are locked which roughly means that a lock of ~$3.33k worth of any of those ERC20 to get 0.01%
    3. Buy in with GENIn this category, 10% are given out. Here you actually have to spend money (GEN tokens). There are 10 individual auctions that each sell 1% to all the bidders. On average people have paid ~20k GEN ≈ $4k per auction on the first 7 one. That means that paying $40 worth of GEN tokens bought you 0.01% voting rights. (how much you get for the remaining auctions only depends on their total volume) The proceeds from those auctions will fully go to the dxDAO and will be used for the curation of proposals.

    ​

    4) Trade on the dutchX This is the biggest category - 50% will be given to traders. Concretely - every trade on the dutchX will generate MGN (Magnolia) - a kind of reward token. 1 ETH trading = 1 MGN generated. MGN generation has only been activated 3 weeks ago and since than 25k worth of ETH has been traded which resulted in 50k MGN generated since buyer and seller receive MGN. That means that currently, a single trade of 10ETH will generate you 10MGN which will give you as well 0.01% of the voting power. Here is the list of the available trading interfaces.Alternatively, there is also a (not very liquid) market for MGN tokens on Uniswap.

    ​

    Why would you care to participate? First of all, if you are not up for experimentation this is probably not the right thing for you. The question we want to find out whether a DAO with currently 318 "co-founder" can outcompete startups with traditionally just 1-4 founders. The dxDAO is free to do everything that is possible on Ethereum but as a starting point, it will get control over the dutchX.

    While still having not too many users the dutchX managed to peak at 1 million daily trading volume and currently ranks 6th of all trading protocols in terms of weekly transaction count. Since February ~$40k in trading fees (liquidity contribution) have been paid. At the moment those are fully used to incentivize additional liquidity. A good overview of trading activity is here.

    Now, what can the dxDAO do?

    - host an alternative interface via ENS/IPFS (e.g. https://fairdex.net and slow.trade are centrally hosted by different entities that have there own rules what tokens to show/ TOS/ geoblocking/ ...)

    - change the fees mechanism / decide how fees are used

    - try to integrate dutchX into other protocols

    - create/fork other DEFI protocols and integrate the dutchX

    - do some form of marketing for dutchX

    - do completely new/ unexpected things...

    ​

    Finally - tips and tricks you should read if you consider participating and a bunch of resources for a deep dive.

    EthereumJS VM v4.0.0-beta.1 Release: TypeScript / EVM Modularization / Promises / Istanbul Process Start

    Posted: 19 Jun 2019 03:28 AM PDT

    Ok folks, you might be shocked to hear, but there are other non Libra-related news to be proclaimed:

    ​

    We finally have a beta release of our VM out, this is the first VM version which is completely written in TypeScript 😀. This release is nevertheless packed with other goodies, the least visible but maybe most important being a deep reaching rewrite of large parts of the internal structure of the inner virtual machine execution logic.

    ​

    Some tldr;:

    • TypeScript
    • EVM Modularization & Major Refactoring
    • Promise-based API
    • Istanbul Process Start (with a draft EIP-1108 alt_bn128 gas cost reduction implementation)

    ​

    Here is the full release description:

    ​

    Since changes in this release are pretty deep reaching and broadly distributed, we will first drop out one or several beta releases until we are confident on both external API as well as inner structural changes. See v4 branch for some major entry point into the work on the release.

    It is highly recommended that you do some testing of your library against this and following beta versions and give us some feedback!

    These will be the main release notes for the v4 feature updates, subsequent beta releases and the final release will just publish the delta changes and point here for reference.

    Breaking changes in the release notes are preeceeded with [BREAKING], do a search for an overview.

    The outstanding work of @s1na has to be mentioned here. He has done the very large portion of the coding and without him this release wouldn't have been possible. Thanks Sina! 🙂

    So what's new?

    TypeScript

    This is the first TypeScript release of the VM (yay! 🎉).

    TypeScript handles ES6 transpilation a bit differently (at the end: cleaner) than babel so require syntax of the library slightly changes to:

    const VM = require('ethereumjs-vm').default

    The library now also comes with type declaration files distributed along with the package published.

    Relevant PRs

    • Preparation, migration of Bloom, Stack and Memory, PR #495
    • StateManager migration, PR #496
    • Migration of precompiles, opcode list, EEI, Message, TxContext to TypeScript, PR [#497 (https://github.com/ethereumjs/ethereumjs-vm/pull/497)

    • Migration of VM.runBlockchain(), PR #517
    • TypeScript finalization PR, config switch, PR #518
    • Doc generation via TypeDoc, PR #522

    EVM Modularization and Structural Refactoring

    New Call and Code Loop Structure / EVM Encapsulation

    This release switches to a new class based and promisified structure for working down VM calls and running through code loops, and encapsulates this logic to be bound to the specific EVM (so the classical Ethereum Virtual Machine) implementation in the evm module, opening the way for a future parallel eWASM additional implementation.

    This new logic is mainly handled by the two new classes EVM (old: Interpreter) and Interpreter (old: Loop), see PR #483 for the initial work on this. The old VM.runCall() and VM.runCode() methods are just kept as being wrappers and will likely be deprecated on future releases once the inner API structure further stabilizes.

    This new structure should make extending the VM by subclassing and adopting functionality much easier, e.g. by changing opcode functionality or adding custom onces by using an own Interpreter.getOpHandler() implementation. You are highly encouraged to play around, see what you can do and give us feedback on possibilities and limitations.

    EEI for Environment Communication

    For interacting with the blockchain environment there has been introduced a dedicated EEI (Ethereum Environment Interface) module closely resembling the respective EEI spec, see PR #486 for the initial work.

    This makes handling of environmental data by the VM a lot cleaner and transparent and should as well allow for much easier extension and modification.

    Changes

    • Detached precompiles from the VM, PR #492
    • Subdivided runState, refactored Interpreter (old: Loop), PR #498
    • [BREAKING] Dropped emitFreeLogs flag, to replace it is suggested to implement by inheriting Interpreter (old: Loop), PR #498
    • Split EVM.executeMessage() with EVM.executeCall() and EVM.executeCreate() for call and create specific logic (old names: Interpreter.[METHOD_NAME]()), PR #499
    • Further simplification of Interpreter/EVM (old: Loop/Interpreter) structure, PR #506
    • [BREAKING] Dropped VM.runJit() in favor of direct handling in EVM (old: Interpreter), officially not part of the external API but mentioning just in case, PR #515
    • Removed StorageReader, moved logic to StateManager, #534

    Istanbul Process Start

    With this release we start the Istanbul hardfork integration process and have activated the istanbul hardfork option for the constructor.

    This is meant to be used experimentation and reference implementations, we have made a start with integrating draft EIP-1108 Istanbul candidate support reducing the gas costs for alt_bn128 precompiles, see PR #539 for implementation details.

    Note that this is still very early in the process since no EIP in a final state is actually accepted for being included into Istanbul on the time of release. The v4 release series will be kept as an experimental series during the process with breaking changes introduced along the way without too much notice, so be careful and tighten the VM dependency if you want to give your users the chance for some early experimentation with some specific implementation state.

    Once scope of Istanbul as well as associated EIPs are finalized a stable Istanbul VM version will be released as a subsequent major release.

    Code Modernization and Version Updates

    The main API with the v4 release switches from being callback based to using promises, see PR #546.

    Here is an example for changed API call runTx.

    Old callback-style invocation:

    vm.runTx( { tx: tx, }, function(err, result) { if (err) { // Handle errors appropriately } // Do something with the result }, )

    Promisified usage:

    try { let result = await vm.runTx({ tx: tx }) // Do something with the result } catch (err) { // handle errors appropriately }

    Code Modernization Changes

    • Promisified internal usage of async opcode handlers, PR #491
    • Promisified runTx internals, PR #493
    • Promisified runBlock internals, restructure, reduced shared global state, PR #494

    Version Updates

    • Updated ethereumjs-account from 2.x to 3.x, part of PR #496

    Features

    • The VM now also supports a Common class instance for chain and HF setting, PRs #525 and #526

    Bug Fixes

    • Fixed error message in runTx(), PR #523
    • Changed default hardfork in StateManager to petersburg, PR #524
    • Replaced Object.assign() calls and fixed type errors, PR #529

    Development

    • Significant blockchain test speed improvements, PR #536

    Cereneum Opens Staking In Less Than 15 Hours!

    Posted: 19 Jun 2019 06:25 PM PDT

    Cereneum Opens Staking In Less Than 15 Hours!

    The Cereneum project launched almost 2 weeks ago, and the claims-only phase is ending soon, and the staking phase will begin. You are still able to claim your tokens during this phase. Once you have claimed your tokens they can be staked sending them to the contract address for a period of time which no one has access to. Cereneum is a trustless and provable way to earn interest, and the developers have no more power than anyone else.

    Here is a medium article written by the lead developer explaining how the team was able to do a trust-less and provable airdrop to all holders of the 5 PoW chains(one of which is Ethereum) that it supports: https://medium.com/@ashketchumnakamoto/how-cereneum-airdropped-to-5-pow-chains-on-the-same-day-a0888b42d959?postPublishedType=initial

    Cereneum works on a concept of pooled interest, meaning the less people staked, the more interest you get. a minimum of 5% of the total supply is minted yearly and given to the staker pool as interest to those staking. If you stake for 90 days you get a 5% bonus to your interest, and this scales linearly to a 100% bonus if you stake for 5 years. Once the staking period opens everyone in the staker pool will start to receive bonus tokens based on redistributed unclaimed tokens. This adds extra incentives for staking. Below is a graph that shows the monthly rewards given to the stake pool based on the total unclaimed tokens. These monthly rewards are calculated daily and given to the pool.

    Adding privacy to Ethereum transactions

    Posted: 19 Jun 2019 10:04 AM PDT

    I've been working on a project that will introduce transaction anonymity for Ethereum. It's based on ideas from CoinJoin and mixing services, but implemented with smart contracts, i.e. decentralized and without any trusted 3rd party. I'd like to make a reusable component that can be integrated into other services and wallet.

    I've described the idea here https://github.com/grandletter/really-nice-mixer and working on a first prototype. Would be glad to hear feedback, it's important for me to hear possible security concerns on the early stage of development.
