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
So as to be suitable 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 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 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 unique announcement.
Improve for Validators
Though this improve has been extensively examined if you’re 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
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 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 have to 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, you want to improve your node. See the “As a non-validator beacon node operator, what do I have to do?”” part under.
As a non-validator beacon node operator, what do I have to do?
Obtain the most recent model of your beacon node consumer, as listed within the desk above.
As a validator, what do I have to do?
Obtain the most recent model of the software program you run, as listed within the desk above. Observe any directions within the launch and restart your node together with your commonplace restart process.
Word, node software program that helps unbiased validator shoppers would require an improve and restart to this part as nicely. 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 outdated guidelines.
Should 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 can 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 must be included within the improve, modifications to the protocol are written into the assorted 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 shall be deserted on the outdated 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 evening sky, rotates fairly quickly with an equatorial velocity of 286 km/s, and is the situation of the Forbidden Planet. Fairly cool star for those who ask us.
Thanks!
Enormous shoutout to the entire researchers, engineers, and neighborhood members which have put an unbelievable quantity of labor into this primary beacon chain community improve.
Now, onward to the Merge 🚀
