- The Sepolia testnet will endure a post-merge execution layer (EL) improve at block 1735371, anticipated on August 17, 2022
- The improve will trigger EL purchasers on the community to disconnect from friends which haven’t transitioned to proof-of-stake. It doesn’t add further performance past this.
- Sepolia node operators should improve their execution layer consumer prior to dam 1735371.
- An identical improve is predicted on Goerli and the Ethereum mainnet as soon as these networks have transitioned to proof-of-stake
Background
With a purpose to preserve a wholesome peer listing, nodes on Ethereum’s execution layer will robotically disconnect friends who do not need the identical improve sequence as them. On the Ethereum mainnet, this implies checking whether or not a peer upgrded to Frontier Thawing at block 200,000, then Homestead at block 1,150,000, and so forth all the best way to the most recent improve, Gray Glacier, which occurred at block 15,050,000. EIP-2124 specifies how that is dealt with. In typical community upgrades, that are triggered by a block top, this occurs robotically as nodes use the block top of upcomming upgrades to filter friends.
For The Merge, this was not potential as a result of the improve was triggered utilizing a whole problem worth somewhat than a block quantity. The rationale for this alternative is defined in EIP-3675:
Utilizing a pre-defined block quantity for the hardfork is unsafe on this context because of the PoS fork alternative taking precedence in the course of the transition.
An attacker could use a minority of hash energy to construct a malicious chain fork that will fulfill the block top requirement. Then the primary PoS block could also be maliciously proposed on high of the PoW block from this adversarial fork, changing into the top and subverting the safety of the transition.
To guard the community from this assault situation, problem gathered by the chain (whole problem) is used to set off the improve.
To attenuate adjustments to the protocol throughout its most advanced improve since launch, the design for The Merge excluded EIP-2124 compatibility. This implies an extra improve should now be achieved so as to add this. You will need to be aware that the one change launched as a part of this improve is specifying a block quantity that nodes can use to establish friends who’ve gone by way of The Merge. No different performance is launched or deprecated as a part of this improve.
Improve Data
Timing
This improve will occur on Sepolia at block 1735371, anticipated on August 17, 2022.
Be aware {that a} comparable improve shall be introduced for Goerli and mainnet after these networks have transitioned to proof-of-stake.
Ropsten will not be upgraded since it’s now thought-about deprecated, together with Rinkeby and Kiln. See this post for extra particulars on their deprecation schedule.
Shopper Releases
Solely execution layer purchasers should be up to date for this improve. Node operators can hold operating their present consensus layer consumer launch on Sepolia by way of the transition.
Be aware that consumer releases used for the Goerli/Prater merge all help this improve on Sepolia. In different phrases, when you already downloaded a launch for the Goerli/Prater merge, you should utilize that very same model on Sepolia for this improve.
Execution Layer
Improve Specs
The specification for this modification is tracked as a part of the Paris specs, beneath the FORK NEXT Improve part.
FAQ
As a node operator, what ought to I do?
You need to improve your execution layer consumer to one of many variations listed above earlier than August 16, 2022. Your consensus layer consumer doesn’t should be upgraded.
As a staker, what do I must do?
The validator set on Sepolia is permissioned. In case you are half of the present Sepolia validators, it’s essential to replace your execution layer consumer to one of many variations listed above on August 16, 2022 on the newest.
In case you are not half of the present Sepolia validator set, you don’t want to do something right now.
Goerli/Prater and mainnet validators might want to comply with the identical steps when this improve is introduced on these networks.
As an utility or tooling developer, what ought to I do?
Nothing, except you’re additionally operating a node. If that’s the case, please improve your execution layer consumer to one of many variations listed above earlier than August 16, 2022.
As an Ethereum person or Ether holder, is there something I must do?
No. The Ethereum mainnet is just not affected by this improve. Even when this improve shall be utilized to mainnet, there will not be any motion wanted.
