Altair Mainnet Announcement | Ethereum Basis Weblog

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

Consumer Variations

With a view to be appropriate with the Altair improve, beacon node operators should replace the consumer model that they run. Should you run a validator, you should improve to proceed to comply with 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 most recent Altair consumer releases previous to the mainnet improve. These include safety patches and optimizations so we advocate *all customers improve to the most recent variations.*

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

Improve for Validators

Though this improve has been extensively examined in case you are a validator on Mainnet, we strongly advocate being on-line through the time of the improve within the occasion that any unforseen points emerge.

Bug Bounty Bonus

With a view 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). Essential Altair bugs in each purchasers and specs at the moment are value 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.

Should you run your personal beacon node, it’s good 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 most recent model of your beacon node consumer, as listed within the desk above.

As a validator, what do I must do?

Obtain the most recent 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 normal restart process.

Be aware, node software program that helps unbiased validator purchasers would require an improve and restart to this element as properly. 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?

In case you are utilizing a beacon node consumer that isn’t up to date to the most recent model (listed above), your consumer will sync to the pre-fork beacon chain as soon as the improve happens. You’ll be caught on an incompatible chain following the previous guidelines.

Should you 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. This may end in penalties with respect to the upgraded Mainnet chain.

What occurs throughout a beacon chain community improve?

After the Ethereum neighborhood involves an settlement regarding which modifications ought to be included within the improve, modifications to the protocol are written into the assorted purchasers. 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 previous chain the place the earlier guidelines could live on.

Why “Altair”?

After neighborhood dialogue and emoji voting, consumer 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 situation of the Forbidden Planet. Fairly cool star should you ask us.

Thanks!

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

Now, onward to the Merge 🚀
