Altair Mainnet Announcement | Ethereum Basis Weblog

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).

Consumer Variations

With a view to be appropriate with the Altair improve, beacon node operators should replace the consumer model that they run. If you happen to 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 under are help the mainnet Altair improve.

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

* Consumer releases referenced with an asterisk have been modified for the reason that 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 in the course of 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 shoppers and specs at the moment are price as much as $100k.

See the bug bounty program for extra particulars.

FAQ

As an Ethereum person 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.

If you happen to run your individual beacon node, you’ll want to improve your node. See the “As a non-validator beacon node operator, what do I must do?”” part under.

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

Obtain the newest model of your beacon node consumer, 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 together with your commonplace restart process.

Be aware, node software program that helps unbiased validator shoppers 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 newest model (listed above), your consumer will sync to the pre-fork beacon chain as soon as the improve happens. You can be caught on an incompatible chain following the previous guidelines.

If you happen to run a validator, the validator shall be unable to take part within the upgraded consensus and can proceed to function on the post-upgrade beacon chain community. This can 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 adjustments must be included within the improve, adjustments to the protocol are written into the assorted shoppers. The beacon chain protocol adjustments are activated at a selected epoch quantity. Any nodes that haven’t been upgraded to the brand new ruleset shall be deserted on the previous chain the place the earlier guidelines might live on.

Why “Altair”?

After group 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 placement of the Forbidden Planet. Fairly cool star should you ask us.

Thanks!

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

Now, onward to the Merge 🚀
