The Altair Beacon Chain improve is able to go dwell on the Ethereum mainnet. The improve will go dwell on Epoch 74240 (Oct 27, 2021, 10:56:23 AM UTC).

shopper model

To be suitable with the Altair improve, Beacon Node Operators Certain Replace the shopper model they’re operating. In case you run a validator, you Certain Improve to proceed following the mainnet beacon chain. Failure to take action will lead to downtime penalty.

The variations listed under assist the mainnet Altair improve.

Edit: The next desk has been edited to seek advice from the newest Altair shopper launch previous to the mainnet improve. These embody safety patches and optimizations so we suggest All Improve customers to the newest model.


*Consumer releases referenced with an asterisk have been modified because the authentic announcement.

Improve for validators

Though this improve has been examined extensively in case you are a validator on the mainnet, we strongly suggest staying on-line in the course of the improve in case any unexpected points emerge.

As a non-verifier beacon node operator, what do I have to do?

Obtain the newest model of your Beacon node shopper, as listed within the desk above.

As a Verifier, what do I have to do?

Obtain the newest model of the software program you are operating, as listed within the desk above. Comply with any directions within the launch and restart your node along with your customary restart process.

In case you run a validator, the validator will likely be unable to take part in superior consensus and can proceed to function on the Beacon Chain community after the improve. It will lead to fines being imposed with respect to the upgraded mainnet chain.

What occurs throughout a Beacon Chain community improve?

After the Ethereum group has reached settlement on which adjustments needs to be included within the improve, adjustments to the protocol are written to varied shoppers. Beacon chain protocol adjustments are activated at a particular epoch quantity. Any node that has not been upgraded to the brand new rule-set will likely be left on the outdated chain the place the earlier ruleset might live on.

Why “Altair”?

Afterwards group dialogue and emoji voting, the shopper groups determined to make use of star names for every improve the place the order of the improve names is in alphabetical order.

Thanks!

Many because of all of the researchers, engineers and group members who’ve put in an unimaginable quantity of labor on this primary Beacon Chain community improve.

Now, onward to the merge 🚀
