Ethereum Report: Validator Economics of Ethereum 2.0 by ConsenSys, Görli Testnet launched, easy-to-install plasma chains by Plasma Group, new Vlad Zamfir’s article about a new crypto-legal system

22nd January — 5th February

This is not financial advice.

During the last two weeks, Ethereum team made progress with the development: Core Devs Meeting took place as Eth2.0 Implementers Call, Prysmatic Labs published their Ethereum 2.0 development update. Görli Testnet (the first cross-client proof-of-authority network for Ethereum) launched. Parity Ethereum 2.2.8-stable/2.3.1-beta: Constantinople + "St. Petersfork" released as Geth Can'tstantinople (v1.8.22) and Pantheon 0.9.1 (ConstantinopleFix and Goerli ready). Plasma Group was introduced. The Beacon Spec for Eth 2.0 is getting closer to completion everyday. Also there was some news on ecosystem projects build on Ethereum: 2M ETH locked in MakerDAO, Status announced the Statusphere Ambassadors, Bounties Network partnered with UNICEF and ETHDenver to prototype a new “positive action token”, Kyber network WBTC is now live on Ethereum and Aragon launched a desktop app. Ethereum ecosystem continues to grow slowly, during these weeks some new projects appeared. A few research articles were published, Vlad Zamfir wrote “Against Szabo’s law, for a new crypto legal system” (with responses from Vitalik Buterin and Gabriel Shapiro). Vitalik Buterin gave a really good talk about CBC Casper. Ethereum 1x Stanford meetings live streams and AraCon videos were published. Diederik Loerakker released his beacon chain schematic. And the last, but not the least — Ethereum community continues to grow and during the last two weeks the number of subscribers of official Ethereum social media channels increased by about 1%.
