The Ethereum network will undergo scheduled network upgrades. Block 15,050,000This is expected to happen in . Wednesday, June 29, 2022. Exact dates may change depending on various block times and time zones. To account for variable block times, please upgrade your nodes before Monday, June 27, 2022.

What is Gray Glacier?

The Gray Glacier Network upgrade changes the parameters of the Ice Age/Difficulty Bomb, pushing it back by 700,000 blocks, or roughly 100 days. This also Byzantium, constantinople, muir glacier, London and Arrow Glacier Network upgrade. No other changes were introduced as part of Gray Glacier.

with Ropsten has now switched to proof-of-stake., the difficulty bomb only affects the Ethereum mainnet. This means that Gray Glacier will not be deployed on any testnets.

client version

To be compatible with the Gray Glacier upgrade, node operators must update the client version they run to one of the versions listed below.


Upgrade Specifications and EIP

Full specifications for the upgrade can be found here: Execution specification repository below gray glacier.md.

Upgrade includes a single EIP. EIP-5133: Difficulty Bomb postponed to mid-September 2022.

Is there anything I need to do as an Ethereum user or Ethereum holder?

If you use an exchange, web wallet service, mobile wallet service, or hardware wallet, you do not need to take any action unless you are instructed by the exchange or wallet service to take further action.

What do I do as a node operator or miner?

Download the latest version of the Ethereum client as listed in the table above.

What happens if I’m a miner or node operator and don’t participate in the upgrade?

If you are using an Ethereum client that has not been updated to the latest version (listed above), your client will be in sync with the prefork blockchain when the upgrade occurs. Depending on the existing rules, you will be stuck on an incompatible chain and will not be able to send Ether or operate on the Ethereum network after the upgrade.

What is Ethereum Land’s network upgrade?

Network upgrades are changes to the underlying Ethereum protocol to create new rules to improve the system. The decentralized nature of blockchain systems makes network upgrades more difficult. Blockchain network upgrades require cooperation and communication with the community as well as various Ethereum client developers to ensure a smooth transition.

What happens during a network upgrade?

After the community reaches a consensus on what changes should be included in the upgrade, the protocol changes will be recorded in various Ethereum clients such as Besu, Erigo, go-ethereum, and Nethermind. Protocol changes are activated at specific block numbers. Any nodes that are not upgraded to the new rule set will be discarded from the old chain where the old rules still exist.

Why “Grey Glacier”?

We generally use Ethereum meeting city names for execution layer network upgrades, but upgrades that only delay difficulty bombs/glaciers use the glacier names instead.

gray glacier It was chosen because of that. literally merge Another glacier, as if Ethereum’s execution layer will soon be merged with the beacon chain!
