The Altair beacon chain upgrade is ready to be activated on the Ethereum mainnet. The upgrade will go live at epoch 74240 (Oct 27, 2021, 10:56:23am UTC). Client Versions In order to be compatible with the Altair upgrade, beacon node operators must update the client version that they run. If you run a validator, you

Earlier this year, the Rayonism hackathon kicked off to protoype the architecture for Ethereum’s transition to proof of stake. The transition, often refered to as The Merge, will keep the existing beacon chain (eth2) and execution layer (eth1) clients, and “merge” both chains by making the beacon chain drive the execution layer’s consensus. This approach

tl;dr Altair is fast approaching. Upgrade your nodes! Now! 🚨Upgrade to Altair before Oct 27🚨 As mentioned in the previous Finalized post, Altair is scheduled to go live at epoch 74240 — Oct 27, 2021, 10:56:23am UTC. See the Altair Mainnet Announcement for details on who, how, and why. Suffice it to say here that

It’s always fun to hear about new grants as they’re awarded, but what happens after the announcement? In this series, we’ll check in on a couple of projects that are well underway – or already at the finish line. Read on to learn about some recent milestones and achievements by grantees! SSZ.dev: Technical Specs and

This issue of Finalized is dedicated to the contextualization of a recently published paper describing three possible attacks on Ethereum’s proof-of-stake algorithm. tl;dr These are serious attacks with a formally-analyzed, technically-simple mitigation. A fix will be rolled out prior to the Merge and will not delay Merge timelines. Forkchoice attacks, mitigations, and timelines There has

The Ethereum network will be undergoing a scheduled upgrade at block number 13,773,000, which is predicted to occur on Wednesday, December 8, 2021. The exact date is subject to change due to variable block times and timezones. Please upgrade your node before Sunday, December 5, 2021 to account for the variable block times. What is

The Ethereum Foundation is allocating 1 million USD in grant funding to organizations that educate governments and policymakers about Ethereum and blockchain technology. We encourage others in the Ethereum community to support their important work. A space to grow, and to do good We understand that transformative technologies raise new questions for regulators and governments.

tl;dr Kintsugi🍵 in progress At the start of November, the Kintsugi🍵 month-long Merge sprint began! Kintsugi specs and milestones/plans were released, and now client teams are deep into the sprint with an aim to launch a persistent testnet in the first week of December. Kintsugi specs incorporate all of the learnings and minor adjustments from
