Announcement on Sepolia Post-Merger Update | Ethereum Foundation Blog

Published:

  • Sepolia’s Testnet will be improved at the EL (Execution Layer) block after merger completion. 1735371Expected to be implemented on August 17, 2022
  • This upgrade will cause EL clients to be detached from any peers that have not yet converted to proof-of-stake. This does not offer any extra features.
  • Prior to the block, node operators must update their EL clients. 1735371.
  • Simultaneous upgrades are expected. Once Goerli and Ethereum have moved to proof-of-stake, they will become mainnet.

Background

To Maintain a healthy peer network, nodes in Ethereum Runtime layer will break off relationships with peers that do not have the same upgrade sequence. On The Ethereum This is how you can tell if your peer is up to date with the mainnet Border thawing Block 200,000 Farm Block 1,150,000 and so on, until the last update. Glacier GrayWhat It happened at block 15,050,000 EIP-2124 This article will explain why this choice was made. In The block height triggers network updates. This occurs when peers use the block height to update their networks.

The Pre-defined block numbers for the hard fork are not secure since the PoS fork’s choice will take precedence during the transition.

An An attacker can use a small amount of hash power to create a malicious chain fork that meets the block height requirement. ThenThe first PoS Block can be maliciously suggested on top of the PoW block of this adversarial knife, becoming the head, and undermining the security of the transition.

To Protect the network against this attack scenario by using the total difficulty (total difficulty), to trigger the update.

To Reduce changes to the protocol during the most complicated upgrade since its release. The Merge was not intended to support EIP-2124. This It means that you will need to update the site to include this feature. It It is important to remember that this update only changes the block number that peers can use to identify peers who have passed through. The Merge. No This update may also introduce or remove other functionality.

Data being updated

Timing

This Updates will take place in Sepolia On the block 1735371Expected on August 17, 2022.

Please Please note that an update similar to this will be announced. Goerli After these networks have been transformed to proof of stake, they will be transferred to the mainnet.
