#RollupDay was 🔥. My favorite hot takes from the panels were:
There is not a single rollup in production today that is censorship resistant, meaning the rollup has permissionless leader election and non upgradeable smart contracts. - @tyneslol
@tyneslol When considering how to move towards decentralizing rollups and in specific decentralizing sequencers, an underdiscussed issue is the creation of massive amounts of MEV from multiple fork choice rule reconciliation. - @tarunchitra
@tyneslol@tarunchitra It's not clear yet that enshrined PBS should actually be implemented in-protocol on Ethereum. There remains unanswered questions around how PBS would interact with other potential protocol changes like single slot finality and other drawbacks. - @ObadiaAlex
@tyneslol@tarunchitra@ObadiaAlex Unlimited data availability (DA) is possible on Ethereum but not desired. To achieve unlimited DA, Ethereum would have to sacrifice qualities of long-term data preservation and throw out unused data or data of low economic value after a certain period of time. -@dankrad
@tyneslol@tarunchitra@ObadiaAlex@dankrad DA layers should diversify its revenue models so that they are not beholden to user demand and only charging congestion costs in the form of tx fees. Operational and capital costs are two other areas of income for a DA layer that should be considered. - @sreeramkannan
Yesterday, I sat down and read the Cosmos 2.0 whitepaper ⚛️ The changes proposed are extensive and while they do obviously benefit $ATOM holders, the ambitious vision for a revamped Cosmos Hub is bound to face delays and introduce new technological risks to the protocol.
The implementation of an upgrade that fundamentally changes the value proposition of ATOM and the functionality of the Cosmos Hub necessitates a degree of prolonged and coordinated action by a core team of developers, not unlike what we see on Ethereum.
The whitepaper does acknowledge the need for new governance bodies (e.g. Cosmos Assembly) and by association new mechanisms for accountability (e.g. Interchain Allocator) to execute the new vision for the Cosmos Hub.
@etherscan Some quick stats before Bellatrix hits:
- network participation rate is 97.79%
- number of active validators is 420404
- number of offline validators 1105
- and client diversity for consensus layer clients
Yesterday, Ethereum core developers discussed at length different attack vectors against the protocol's censorship resistance following the Merge upgrade and what strategies should be taken to uphold the protocol's integrity in the face of potential state level opposition.
The concerns around Ethereum's censorship resistance as a soon-to-be proof-of-stake blockchain stem from the rattling repercussions of recent sanctions placed against @TornadoCash by the U.S. government. Read more about those repercussions here: docsend.com/view/b9punqc4q…
@TornadoCash Many Ethereum developers were adamant that the censorship resistant qualities of the network should be upheld at all costs. But it wasn't as clear cut what developers felt was necessary to do now before the Merge upgrade in light of recent controversy.
Ethereum core developers wrapped up their 142nd ACD call today.

Livestream:
My recap of the meeting below 👇🪡
PSA before I start the thread: Starting on July 21st, these bi-weekly meetings will be held on Thurs instead of Fri, which means my Fri afternoons from now on will be free for other activities. Yay! Also @TimBeiko wrote up an excellent thread already of today’s call.
For another perspective of the call, check out his thread 👇. As usual, devs spent a lot of time talking about the Merge upgrade. In particular, devs discussed learnings from the Sepolia Merge activation, which went live on Wed.
Ethereum devs have their 8th mainnet shadow fork to test the Merge coming up. @parithosh_j gave an update on preparations for it and said TTD is expected to hit sometime next Tuesday. But coming up sooner than that is the Merge activation on the Sepolia testnet.
I saw some estimations suggesting TTD will hit on Sepolia as early as tomorrow. For more details around Merge activation on Sepolia, read this blog post: blog.ethereum.org/2022/06/30/sep….
.@TimBeiko kicked off the call with a reminder about the Gray Glacier hard fork happening next week on Ethereum. The upgrade is expected to hit around Wed, June 29. Full details about the fork and accompanying client releases here: blog.ethereum.org/2022/06/16/gra…
Next, devs discussed Merge testing related items, starting with a debrief on how the 7th mainnet shadow fork went this past Wednesday. TLDR, it went poorly. 20% of nodes dropped off right at Merge activation and even more nodes dropped off thereafter.
