Ethereum(ETH) Sepolia Post-Merge Upgrade

• The Sepolia testnet will undergo a post-merge execution layer (EL) upgrade at block 1735371, expected on August 17, 2022
• The upgrade will cause EL clients on the network to disconnect from peers which have not transitioned to proof-of-stake. It does not add additional functionality beyond this.
• Sepolia node operators must upgrade their execution layer client prior to block 1735371.
• A similar upgrade is expected on Goerli and the Ethereum mainnet once these networks have transitioned to proof-of-stake
