Ethereum’s diverse client ecosystem is at the foundation of all that we’re building together. This includes both execution-layer and consensus-layer clients, both of which are essential parts of Ethereum’s post-merge future. Supporting execution-layer (formerly “Eth1”) clients remains one of the Ethereum Foundation’s highest priorities. These client teams have supported Ethereum’s growth over the past several

The Road to Altair edition 🛣⭐️ tl;dr Pyrmont forks, testing in progress After a series of small but very valuable Altair devnets, Pyrmont — a large public testnet — upgraded last week. The transition to Altair went off without a hitch, setting the stage for the next wave of testing and upgrades. This week, Pyrmont

Does development of the core protocols that power the Ethereum blockchain excite you? Are you interested in getting involved at the most fundemental and technical levels of the Ethereum protocol? I am excited to announce that we are now accepting applications for the second cohort of the Core Developer Apprenticeship Program (CDAP)! What is CDAP

Earlier this year, we launched a bug bounty program focused on finding issues in the beacon chain specification, and/or in client implementations (Lighthouse, Nimbus, Teku, Prysm etc…). The results (and vulnerability reports) have been enlightening as have the lessons learned while patching potential issues. In this new series, we aim to explore and share some

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!

Altair is here; the Merge is coming. tl;dr Altair upgrade, Oct 27 Altair, the first mainnet upgrade to the Beacon Chain, has been scheduled for epoch 74240 (Oct 27, 2021, 10:56:23am UTC). A subtle but great advantage of proof-of-stake is that we can precisely time upgrades (Sorry Tim! We’ll be done with proof-of-work soon 😉)

The ethereum.org Translation Program has been live for over two years, and we are excited to share a couple of milestones we have hit since its inception, as well as some of our plans for the future. Since we launched the initiative in 2019, over 2,000 community members have contributed, translating a total of 2.8

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
