first level titlePhase 0: Beacon ChainVersion 0.12.0 of the specification has been released, and it has a very interesting name:
(isolation haircut).
This release focuses on updates to the highly anticipated BLS signature standard, including updates toNegative punishment。
(“Secondary Leakage”) adjustment. If four epochs pass without a checkpoint being finalized, a negative penalty is applied. The idea is to slash the deposits of lazy validators, forcing them to be evicted from the network, and the remaining active validators can finalize the blockchain again (which could take weeks in practice).
If validators are working properly, they should not be penalized. However, according to the previous specification, even if the verifier performs its duties well, it may suffer certain economic losses. In this version of the specification, this no longer happens. As long as validators participate in the work normally, they will not suffer losses.Another important development is the update of the libp2p Gossipsub protocol toversion 1.1The client team is also currently working on implementing the new version. This version will be used as one of the basic components of the multi-client test network, and if there are no major problems, it will be used when the network is officially launched.Incidentally, also for

. This simulates dealing with similar surprises in a real network and is a useful test case.
existEveryone is so busy these days that it's easy to bury important solutions in a sea of PRs. This situation will improve in the future, and similar situations must be handled and coordinated very carefully.testnetSunset in Schlesi

Some details are given in the update. The process is as follows:
This happens when the number of participants is small. One possible cause is Teku's failure to include a large number of proofs in its blocks.
PrysmandLighthouseEither way, this leads to a "quadratic leak" aimed at weeding out validators who did not participate in the work.
At the same time, the first forfeiture occurred.Immediately afterwards, Prysm, Lighthouse, and Teku were unable to reach consensus with each other, and a three-way fork occurred.and
Both fail to negatively penalize slashed (not expelled) validators

Teku's performance is within specification
Process of multi-client testnetvery hard, to make vulnerabilities invisible, we need to put a lot of pressure on the network. Both inability to finalize and validator slashing events are very meaningful challenges for us.
Teku was the last functioning client on the network, but we also narrowly escaped death. Once finality is lacking, the memory used starts growing infinitely, with the end result forcing the majority of Teku nodes out of the network.
We provide a huge storage space for a pair of partners. Although we can cope with it temporarily, it is also stretched and we should not be able to last for a long time. usSolving。
