Altair is right here; the Merge is coming.

tl;dr

Altair improve, Oct 27

Altair, the primary mainnet improve to the Beacon Chain, has been scheduled for epoch 74240 (Oct 27, 2021, 10:56:23am UTC).

A delicate however nice benefit of proof-of-stake is that we are able to exactly time upgrades (Sorry Tim! We’ll be performed with proof-of-work quickly 😉)

This improve brings light-client help to the core consensus, cleans up beacon state incentive accounting, fixes some points with validator incentives, and steps up the punitive params as per EIP-2982.

Enormous shout-out to shopper groups for his or her work on this all year long 🙌

Hold your eyes peeled for one more blogpost on Monday, October 4th. It will embody all mainnet Altair releases.

After which you’ll be able to improve your nodes!

Merge interop specs and coming devnets

The Merge Interop spec was launched on Friday. This “meta-spec” gives steady targets for engineers for an preliminary wave of testing and devnets.

After a flurry of specification exercise over the previous few months, Merge specs are close to characteristic full, and the core logic is steady. On this subsequent part, engineers will construct out the Merge logic and check their software program with different groups on short-lived devnets. The engineers will vet the specs as they stand right this moment and supply dynamic suggestions into the specs to refine and/or repair points as they come up.

On the prime of the checklist is to validate and refine the Merge engine API and to prototype and specify varied variations of sync below the Merge paradigm.

Proof-of-stake superceding proof-of-work is years within the making, and we’re simply as excited as you to see it in motion. A lot enjoyable coming in October 🏺🚀
