Notes of RollCall #8
Pasted from hackmd: RollCall #8 Summary - HackMD
RIP 7755 - Contract standard for cross L2-calls
- Presented by Wilson from the Base team
- PR link: https://github.com/ethereum/RIPs/pull/31
- The goal of this RIP is to provide low level specification for arbitrary cross-chain calls, to be maximally on chain, and to provide a proof system with minimal trust assumptions
- Discussion
- Andreas Freund raised the question regarding the max time duration to fulfil a call, especially for time-sensitive txns, and another question regarding the time frame of finalityDelaySeconds.
- Elizas Tazartes raised the question regarding the relationship of storage proof & state root, and what exactly the storage proof tries to prove.
- Another suggestion on the finality delay is to include values boundaries as an indication to the wallets.
- Areas need further exploration: Standardization of the pieces needed for the proofs
- Unified way of exposing a trusted L1 block hash/ state root on L2
- Standardize where state roots live on L1
- Common way of describing pending vs finalized state roots on L1
L1 & Pectra updates
- Presented by Ansgar
