1. About the beacon chain
paperpaper, claiming that in the first 8 months of the beacon chain's lifecycle, 478 violations went undetected and therefore went unpunished.
If true, this is definitely a serious incident. This means that confiscible crimes occur four times more often than we thought. And, worse, they go undetected, effectively rendering the entire network-slashing mechanism useless.
Of particular concern is that one of our own team's ETH2 validator accounts was listed as the offender, and we know we haven't done anything weird with the configuration, so it could just be a client bug.
Long story short, Eth2 developers jumped into action and soon realized that, as each breach was investigated, the results were bogus based on actual beacon chain client data. All evidence points to an indexing error in the beaconcha.in browser, which the paper's authors confirm is their only source of data. The whole premise of the paper seems to be incorrect.
I have said many times that I sincerely welcome academic engagement and scrutiny of what we do here: it is very important. But I'm really confused about the way I seek to publish an "aha, got it!", paper that hasn't been reviewed by the core developers. If we investigate early on, we can save everyone a lot of time, not to mention embarrassment.
On the positive side, we got some better tools out of it, found a beacon in a bug, and enjoyed a little comic moment. (Yes, Paul H is running an ETH2.0 client.)

2. About The Merge
Even more exciting,Kiln v2The Merge specification has been released. This adds something to what we're running on merge-devnet-4, and makes one breaking change.
Authentication has been added to EngineAPI.
It provides an optional nifty feature to check that the two paired clients (Eth1 and Eth2) are configured correctly.
random has been renamed to prevRandao after discussions at the last all core devs meeting. This is a breaking change.
Don't forget, you can follow the progress of the client implementation via the Kiln tracker and the overall progress in the ETH1 and ETH2 merge readiness checklist.
Kiln Public Testnet
The public Kiln testnet is expected to launch early or mid next week. Not all clients support authentication on this engine API, but it is currently optional. As long as everyone renames random to prevRandao in time, we're good to go.
As a reminder, we expect this to be the last dedicated testnet before we start forking the existing testnet for The Merge. Kiln v2 should be the final merged spec barring some potentially non-substantial cleanup.

3. Staking
Rocket Pool hits 1% - keep going up and up! Anthony Sassano describes this in The Daily Gwei. My friend Sephiroth at Allnodes wrote about Rocket Pool for Nasdaq.com.
articlearticle. Phiz talked about the development of pools.invis.cloud which provides a good insight into where the primary responsibility for our current unbalanced client distribution lies.
articlearticleExplains how their Vouch "multi-node validators" can help increase customer diversity. Note that Vouch now supports Nimbus as a beacon node.
Rated.network made new progress this week, partly to correct theirBulletin articleURL, partly because they have some front-end improvements and a new API. Their ultimate goal is to crowdsource transparency around the performance of staking services.
A big leap forward in Distributed Validator Technology (DVT) was the release ofspecifications. My colleagues at ConsenSys Protocol R&D are currently working to formally verify this. If you're wondering what I'm talking about, Superphiz wrote a mini explanatory article on DVT, and both Carl and Aditya gave great short talks on DVT at EthDenver last week.

Research
The Danksharding workshop was held on February 14th.video playbackWatch it here. It took Dankrad an hour to complete the proposed new data sharding (or data sampling) design, and then Vitalik completed his blob-transactions proposal. Slides, links to Eth Magicians discussion topics, and other resources are from the workshop overview.
In other Danksharding related news, Protolambda and team prototyped blob transactions at EthDenver. I should explain that blob transactions are an intermediate step towards full darksharding and can be implemented in the first post-merge upgrade (currently called the Shanghai upgrade). These will give Rollup some huge scalability benefits.
There are also plans to include validator balance withdrawals in the Shanghai upgrade. Activities in this area are increasing. Two versions are being explored,andandpush withdrawal, the latter for prototyping in Geth. This "pull" version is automatic once a validator exits and becomes withdrawable, while the "push" version is initiated by a beacon chain message. (Maybe. I don't know.) Lots of talk about PR links, and here's a Twitter thread with more good stuff.

Vitalik willinner product parameterConsidered as an alternative to KZG commitments for data availability sampling. The main motivation is to avoid the trusted setup needed for polynomial commitments, but I don't think that's a big deal. (When he says "the risk in practice is high", he means "low".) Anyway, this is an interesting read and primer on the subject.

Implementer
Conference Call #82 was held on February 24th.
We have some plans for the Kiln public testnet. Not all client teams are fully up to date with the new Kiln v2 spec, but we've come up with a workaround so we can launch testnet as quickly as possible.
We talked about some equity/reward withdrawal mechanisms -some designsWork is in progress.
