Danny Ryan’s “Altair Mainnet Announcement” invites all Ethereum 2.0 node operators to upgrade their software in order to avoid the validator downtime penalty.
Altair will go live on October 27, 2021.
The Altair beacon chain (ETH2 initial phase) upgrade will go live in mainnet at epoch 74240, according to Mr. Ryan’s official blog post. This epoch is expected to occur on October 27, 2021, at 10:56 a.m. UTC.

Upgrade your nodes!
Now, onward to the Merge 🚀

Node operators should upgrade their clients to keep their nodes synchronized with post-Altair consensus. The announcement includes links to software builds for all clients (Lighthouse, Lodestar, Prysm, Nimbus, and Teku).
End users, ETH holders, contracts, and the state of the PoW network are unaffected by the updates, as they were with Ethereum 1.0 hardforks.
The Ethereum 2.0 upgrade Altair is intended to advance the economic logics of network validation while also introducing “light client” support for its core consensus.
“Towards the Merge”
To ensure the security and performance of the post-Altair network, EF launches a massive bug bounty campaign. Ethereum enthusiasts can report bugs and receive up to $100,000 in bounty bonuses before November 27, 2021.
Merge With Confidence
As a result, the Ethereum 2.0 network is one step closer to completing the ETH1-ETH2 transition. At the time of writing, more than 7.8 million Ethers were locked in the ETH2 deposit contract.
This amount now exceeds $27 billion in equivalent value, owing to the recent crypto capitalization surge. To put this in context, the “capitalization” of the Ethereum 2.0 deposit contract is greater than that of Yandex, Kia, Deutsche Bank, Panasonic, and Societe Generale.
