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).
As a way to be suitable 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 lead to downtime penalties.
The variations listed beneath are assist the mainnet Altair improve.
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
As a way 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 are actually value as much as $100k.
See the bug bounty program for extra particulars.
As an Ethereum person or Ether holder, is there something I have to 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.
If you happen to run your individual beacon node, you want to 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 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. 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 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’s not 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 can be caught on an incompatible chain following the previous guidelines.
If you happen to 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 may lead to 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 needs to 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 will likely be deserted on the previous chain the place the earlier guidelines could live on.
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.
Big 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 🚀
That is an emergent and evolving extremely technical area. If you happen to select to implement the suggestions on this publish and proceed to take part, you must ensure you perceive the way it impacts you. It’s best to perceive that there are dangers concerned together with however not restricted to dangers like surprising bugs. By selecting to implement these suggestions, you alone assume the dangers of the implications. This publish and suggestions usually are not a sale of any variety, and don’t create any warranties of any variety together with however not restricted to something associated to the Ethereum community, or the Ethereum shoppers referred to herein.
