Phase 0: Beacon Chain
eth2 progress snapshot #15
", as usual, presents us with refined and authoritative information, and readers who want to save time can read this article first.Phase 0: Beacon ChainNo big news from the testnet front. Since Medalla recovered from the turmoil two weeks ago, things have been running smoothly. At present, more than 42,000 validators have been activated, and there is still a ten-day-long queue waiting to join. Validator participation is healthy at around 80%. Blocks also remain finalized.
We plan to do it again at the end of this monthcreationA test of the process, applying lessons learned from the creation of Medalla. This test will not affect the operation of the Medalla test network, and the test beacon chain will only run for a few days. The Launchpad portal has been updated according to the test. The deployment of the test and deposit contract will be around the 21st, and the corresponding genesis time is expected to be a week thereafter. More information on this will be released in the coming weeks.Follow up on GitHub！

Users can voluntarily opt out of beacon chain validation and eventually claim their deposit back, along with any accrued rewards. However, since the deposit needs to be withdrawn somewhere, this facility will have to wait until the economic mechanisms in the Eth2 ecosystem are up and running.suggestionSince we do not fully grasp how the economic mechanism will work at first, the beacon chain currently only provides a minimum feasible exit mechanism. When registering for staking, users will be responsible for the withdrawal keys they hold. There will be a way in Eth2 to prove that the user owns the corresponding key, and the user can then transfer the proposed deposit to an account.Now that the focus has come to Phase 1.5 (see below), this mechanic can be extended in some interesting ways. For example, VitaliksuggestionSet a corresponding Eth1 address for the withdrawal key. This could be a contract on Eth1 that will centralize and distribute withdrawals in phase 1.5. it seemsnot difficultaccomplish. Martin Köppelmann on thisfeel excited

Phase 1.5: Merge of Eth1+Eth2Please note that while we have been focusing on the delivery of the Phase 0 Beacon Chain, work on subsequent phases is ongoing in parallel. The aptly named Phase 1.5, where the Eth1 chain will be merged into the Eth2 system and usher in full proof-of-stake.As originally conceived, this plan is part of phase 2 (full implementation of the execution environment on Eth2). But in recent months the plan has grown in urgency and has been brought forward in the roadmap.prototype demo。

podcastbeaconcha.inAlso very good. The first thirty minutes mainly reviewed and looked forward to the challenges faced by the Medalla testnet, and also included some discussions on how to participate.Proof that packaging is a very hot topic these days. Whether your validator proof can be efficiently packaged into the beacon block is one of the important indicators of performance, which is directly related to the reward of the validator.Last time we mentioned,Currently being able to show a "prove efficiency" metric for validators is attracting a lot of attention. We also recently performed aefficiency optimization, Adrian Sutton produced a。

This work is more valuable for the stage after Eth2.0, as far as the current plan is concerned, we do not rely on it. But it's really rewarding work, especially for apps.
ZenGo has been analyzing the trusted settings required by VDFs and has written anew attack method, called "DogByte".

Another big news is the development pause of the Trinity Eth2 client. This is a Python client developed by the Ethereum Foundation. Trinity is open source and everyone is welcome to contribute. But the Trinity team will now focus on collaborating with other teams to launch the Beacon Chain mainnet.
