Grey Glacier Improve Announcement | Ethereum Basis Weblog

The Ethereum community can be present process a scheduled community improve at block 15,050,000, which is anticipated to happen on Wednesday, June 29, 2022. The precise date is topic to alter attributable to variable block instances and time zones. Please improve your node earlier than Monday, June 27, 2022 to account for variable block instances.

What’s Grey Glacier?

The Grey Glacier community improve modifications the parameters of the Ice Age/Problem Bomb, pushing it again by 700,000 blocks, or roughly 100 days. This has additionally been finished within the Byzantium, Constantinople, Muir Glacier, London and Arrow Glacier community upgrades. No different modifications are launched as a part of Grey Glacier.

With Ropsten now transitioned to proof-of-stake, the issue bomb solely impacts the Ethereum mainnet. This implies Grey Glacier is not going to be deployed on any testnet.

Shopper Variations

With a view to be suitable with the Grey Glacier improve, node operators might want to replace the consumer model that they run to one of many ones listed under:

Improve Specification and EIPs

The total specification for the improve may be discovered within the execution-specs repository underneath gray-glacier.md.

A single EIP is included within the improve: EIP-5133: Delaying Problem Bomb to Mid September 2022.

As an Ethereum consumer or ether holder is there something I must do?

If you happen to use an alternate, an online pockets service, a cellular pockets service, or a {hardware} pockets you do not want to do something until you might be knowledgeable to take extra steps by your alternate or pockets service.

As a node operator or miner, what do I must do?

Obtain the most recent model of your Ethereum consumer, as listed within the desk above.

What occurs if I’m a miner or node operator and I don’t take part within the improve?

If you’re utilizing an Ethereum consumer that isn’t up to date to the most recent model (listed above), your consumer will sync to the pre-fork blockchain as soon as the improve happens. You’ll be caught on an incompatible chain following the previous guidelines and you’ll be unable to ship Ether or function on the post-upgrade Ethereum community.

What’s a community improve in Ethereum-land?

A community improve is a change to the underlying Ethereum protocol, creating new guidelines to enhance the system. The decentralized nature of blockchain techniques makes a community improve harder. Community upgrades in a blockchain require cooperation and communication with the neighborhood, in addition to with the builders of the assorted Ethereum purchasers to ensure that the transition to go easily.

What occurs throughout a community improve?

After the neighborhood involves an settlement regarding which modifications needs to be included within the improve, modifications to the protocol are written into the assorted Ethereum purchasers, akin to Besu, Erigon, go-ethereum and Nethermind. The protocol modifications are activated at a particular block quantity. Any nodes that haven’t been upgraded to the brand new rule set can be deserted on the previous chain the place the earlier guidelines live on.

Why “Grey Glacier”?

Whereas we usually use Ethereum convention metropolis names for execution layer community upgrades, upgrades that solely delay the issue bomb/ice age use glacier names as an alternative.

Grey Glacier was chosen as a result of it actually merges into one other glacier, similar to how Ethereum’s execution layer will quickly be merged with the Beacon Chain!
