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).
Shopper Variations
With a view to be appropriate with the Altair improve, beacon node operators should replace the consumer model that they run. In the event 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 newest Altair consumer releases previous to the mainnet improve. These include safety patches and optimizations so we suggest all customers improve to the newest variations.
* Shopper releases referenced with an asterisk have been modified for the reason that unique 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
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). Important Altair bugs in each purchasers and specs are actually 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 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.
In the event you run your personal beacon node, it is advisable improve your node. See the “As a non-validator beacon node operator, what do I have to do?”” part beneath.
As a non-validator beacon node operator, what do I have to do?
Obtain the newest model of your beacon node consumer, as listed within the desk above.
As a validator, what do I have to do?
Obtain the newest 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.
Be aware, node software program that helps impartial validator purchasers 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?
If you’re utilizing a beacon node consumer that’s not 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’ll be caught on an incompatible chain following the outdated guidelines.
In the event you run a validator, the validator will likely 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 adjustments ought to be included within the improve, adjustments to the protocol are written into the assorted purchasers. The beacon chain protocol adjustments are activated at a particular epoch quantity. Any nodes that haven’t been upgraded to the brand new ruleset will likely be deserted on the outdated chain the place the earlier guidelines could live on.
Why “Altair”?
After community discussion 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 placement of the Forbidden Planet. Fairly cool star in the event you ask us.
Thanks!
Enormous shoutout to the entire 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 🚀
