Altair Mainnet Announcement | Ethereum Foundation Blog

The Altair beacon chain improve is able to be activated on the Ethereum mainnet. The improve will go dwell at epoch 74240 (Oct 27, 2021, 10:56:23am UTC).

Shopper Variations

So as to be suitable with the Altair improve, beacon node operators should replace the shopper model that they run. For those who run a validator, you should improve to proceed to observe the mainnet beacon chain. Failure to take action will end in downtime penalties.

The variations listed beneath are help the mainnet Altair improve.

EDIT: The next desk has been edited to reference the newest Altair shopper releases previous to the mainnet improve. These comprise safety patches and optimizations so we suggest all customers improve to the newest variations.

* Shopper releases referenced with an asterisk have been modified because the authentic announcement.

Improve for Validators

Though this improve has been extensively examined if you’re a validator on Mainnet, we strongly suggest being on-line through the time of the improve within the occasion that any unforseen points emerge.

Bug Bounty Bonus

So as to get extra eyes on the Altair improve, all bounties for vulnerabilities associated to the Altair improve have been doubled between now and 4 weeks after the launch (Nov 27). Vital Altair bugs in each shoppers and specs at the moment are price as much as $100k.

See the bug bounty program for extra particulars.

FAQ

As an Ethereum consumer or Ether holder, is there something I must do?

This improve is solely for the beacon chain consensus mechanism and does not have an effect on end-user accounts, contracts, and state secured by the proof-of-work chain.

For those who run your personal beacon node, you’ll want to improve your node. See the “As a non-validator beacon node operator, what do I must do?”” part beneath.

As a non-validator beacon node operator, what do I must do?

Obtain the newest model of your beacon node shopper, as listed within the desk above.

As a validator, what do I must do?

Obtain the newest model of the software program you run, as listed within the desk above. Comply with any directions within the launch and restart your node along with your customary restart process.

Observe, node software program that helps unbiased validator shoppers would require an improve and restart to this part as effectively. Please learn warnings and directions contained within the official releases.

What occurs if I’m a validator or node operator and I don’t take part within the improve?

If you’re utilizing a beacon node shopper that isn’t up to date to the newest model (listed above), your shopper will sync to the pre-fork beacon chain as soon as the improve happens. You’ll be caught on an incompatible chain following the outdated guidelines.

For those who run a validator, the validator might be unable to take part within the upgraded consensus and can proceed to function on the post-upgrade beacon chain community. It will end in penalties with respect to the upgraded Mainnet chain.

What occurs throughout a beacon chain community improve?

After the Ethereum group involves an settlement regarding which modifications must be included within the improve, modifications to the protocol are written into the varied shoppers. The beacon chain protocol modifications are activated at a selected epoch quantity. Any nodes that haven’t been upgraded to the brand new ruleset might be deserted on the outdated chain the place the earlier guidelines could live on.

Why “Altair”?

After group dialogue and emoji voting, shopper groups determined to make use of star names for every improve the place the sequence of improve names are in alphabetical order.

Altair begins with a “A”, is the twelfth brightest star within the night time sky, rotates fairly quickly with an equatorial velocity of 286 km/s, and is the placement of the Forbidden Planet. Fairly cool star in case you ask us.

Thanks!

Large shoutout to the entire researchers, engineers, and group members which have put an unimaginable quantity of labor into this primary beacon chain community improve.

Now, onward to the Merge 🚀
