Chain Infra

Gateway : Issues with Erigon archival nodes caused by snapshots.Erigon team knows, there’s an issue on GitHub. There is a workaround.


Shadowfork? There are two observations for Chiado. The state seems to be increasing way faster than before. It might just be related to the withdrawals in blocks, as previously Chiado blocks were mostly empty. Block processing is ~20ms slower. Might also just be linked to withdrawals in blocks. The gas usage is around the same, but system transactions don’t count towards that limit. Might be worth checking this on mainnet with a shadowfork Chiado upgrade Add debug logs to system level transactions to see how much gas they consume. It should be the same for mainnet and chiado Deposit UI: Staking providers, Rocket pool, Stakewise, Etc


Storage layout issue? gnosischain/deposit-contract#46 Attach storage layout maps comparison to the PR for clarity

Agreed on Slot 10379264 ts 1690889660 UTC Tue 01/08/2023, 11:34:20

Most people from Nethermind will be available. Andrew from erigon team will be available. Somebody from Gateways will be available most likely. Giacomo won’t be available. Releases expected as soon as possible with expected date of ~ 2 weeks

Can Ruben independently check the slot and times so we don’t have the same issue as on Chiado? Test to check if timestamp valid were added on Nethermind


Coinbase issue There are two checks for the account access cost. Hardcoded value that is failing on pre-shanghai Will check with Mario. On post-shanghai we have warm coinbase due to EIP-3651. So it’s not a blocker for the hard fork at all

Issue with Erigon Marcos is already checking with Andrew


Script ran and verified the transfer events for withdrawals Process Fetch withdrawals and transfer events Compare the two Might want to check all gno.balanceOf(address) values in between How was the contract upgraded regarding the storage layout?
