@raulvk @_julianma @donnoh_eth @dannyryan @luca_zanolini @mkalinin2 Probably best for validators not to run FCR, just to avoid possible delays due to the extra computation.

I think this website could benefit from: 1. a clear walkthrough of what needs to happen for assumptions to break; i.e. the sequence of conditions that need to stack at once 2. a historical analysis of when those conditions have been met (or been close) over the lifetime of the chain One obvious rule is that FCR should be disabled locally at fork boundaries and during degradation. Not sure if it’s sufficiently clear that FCR on/off is a dynamic local choice, and what vital stats are worth monitoring.

fastconfirm.it The fast confirmation rule is incredible So many years in the making. Super excited to see it finally ship!

Great post by Luca explaining why Dynamic Availability matters for Ethereum!

13-second confirmations are coming to Ethereum! For many applications, this could replace waiting 13+ minutes for finality.

Seoul is officially home! Found the perfect way to mark my first local appearance: speaking at @buidl_conf! Thanks @ekang426 for the invite. I’ll be sharing our work at the @ethereumfndn on consensus & fast confirmation! Builders, let’s connect! #BUIDLAsia #Ethereum #Seoul

@benjaminion_xyz @ethereumfndn This was written in the stars!!! Looking forward to working with you...again!!!

I left paid work almost a year ago saying that only something spectacular would drag me out of retirement. Well, it happened - I am now with @ethereumfndn helping to shepherd fast finality to Mainnet. It's going to be quite the journey, but I am very excited! 🚀

We present Majorum, an ebb-and-flow consensus protocol with dynamic quorums. Our paper got accepted at FC (Financial Cryptography) 2026! @fradamt @robsaltini @thanh_hai_tran @yannvon

Finality is the belief that some things won’t change in the future. In our new post, we unpack how this belief works in blockchains: why it’s conditional, and how its strength evolves over time. Together with @ittaia and @VitalikButerin, we explore this conditional notion of finality. decentralizedthoughts.github.io/2025-11-23-fin…

And here we are, < 1M active validators. Important to keep this momentum going, and even accelerate. EIP-8061 (increasing the churn limit) can make the process fast once the ball gets rolling, while EIP-8062 (withdrawal fee on the sweep) can incentivize 0x02 adoption

1) Thrilled to announce the launch of the new Columbia-Ethereum Research Center on Blockchain Protocol Design! This center will be hosted by @CUSEAS, with funding support by @ethereumfndn, and directed by @Tim_Roughgarden.

1/🧵 Applications for the EF 2026 Internship Program are now open. A paid, full-time, 12-week opportunity to work directly with the teams advancing the Ethereum protocol and ecosystem.

L2 interop working group + special focus this week on accelerating L1 fast finality 🔥🔥 Highly recommend watching / taking a look at the notes below to get the latest on: 1. Fast Synchronous Finality (aka the fast confirmation rule) 2. ENS-based chain registry 3. Sync composability designs from ssv network 4. L2 withdrawal windows Notes and recording: @rudolf/interop-15" target="_blank" rel="nofollow noopener">notes.ethereum.org/@rudolf/intero… thanks to this week's guests @robsaltini @mkalinin2 @unruggable_eth @wonderland @ssv_network

I'm so excited for this research center! Tim is a powerhouse and incredible magnet for talent. I can't wait to see all their contributions to Ethereum (and blockchain protocol design more generally). Super bullish on such cross-pollination between academia and practitioners!

With @robsaltini, we dive into adapting 3SF to ePBS, FOCIL & PeerDAS — features the original protocol didn’t consider. We examine how these components interact and whether their integration could create challenges or incompatibilities in this new context. ethresear.ch/t/integrating-…

Our new fuzzer for zkVMs discovered a critical soundness bug in RISC Zero! 🔥 @RiscZero Thanks a lot for the shout-out! We're happy to contribute to making RISC Zero more safe! 🚀 Building complex ZK infrastructure? Let us help you secure it. Get in touch! ✉️

Thanks @drinkcoffee2010 for hosting our presentation on our proposal for a faster finality and reorg-resilient consensus protocol for Ethereum.

Delighted to share that our paper, co-authored with @fradamt, @robsaltini, and @thanh_hai_tran, has been accepted for presentation at @ICDCS2025: arxiv.org/abs/2310.11331

@benjaminion_xyz @OPLabsPBC Great to hear that L1 got you back! L2 will surely miss you!

So, news is spreading that I left @OPLabsPBC, and people are asking what's next. Tl;dr - I'm getting back to The Book (Upgrading Ethereum, sometimes known as the Eth2 Book). 👇

It was a pleasure to present our work on a Fast Confirmation Rule for Ethereum at #PEEPanEIP! This is a joint effort with @adiasg @fradamt @luca_zanolini and Chenyi Zhan. Thank you for having me!
