The Altair beacon chain improve is able to be activated on the Ethereum mainnet. The improve will go stay at epoch 74240 (Oct 27, 2021, 10:56:23am UTC).
Consumer Variations
With the intention to be appropriate with the Altair improve, beacon node operators should replace the shopper model that they run. In case 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 under are assist the mainnet Altair improve.
EDIT: The next desk has been edited to reference the most recent Altair shopper releases previous to the mainnet improve. These comprise safety patches and optimizations so we suggest all customers improve to the most recent 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 if you’re a validator on Mainnet, we strongly suggest being on-line throughout the time of the improve within the occasion that any unforseen points emerge.
Bug Bounty Bonus
With the intention 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 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 only 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.
In case 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 under.
As a non-validator beacon node operator, what do I must do?
Obtain the most recent model of your beacon node shopper, 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 commonplace restart process.
Notice, 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 shopper that isn’t up to date to the most recent 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.
In case you 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 may 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 needs 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 particular epoch quantity. Any nodes that haven’t been upgraded to the brand new ruleset shall be deserted on the outdated chain the place the earlier guidelines might live on.
Why “Altair”?
After community discussion 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 evening sky, rotates fairly quickly with an equatorial velocity of 286 km/s, and is the placement of the Forbidden Planet. Fairly cool star in the event you ask us.
Thanks!
Enormous shoutout to all the 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 🚀
