Design for L1StateRoot Contract

[kyzooghost]

Description

Throughout our investigation and discussions on storing an L1 state root on L2, a common element in many of the proposed solutions is a contract on L2 that will store the L1 state root as a public state variable. We should draw from the following open source specifications for this contract:

• https://github.com/ethereum/RIPs/blob/master/RIPS/rip-7859.md
• https://eips.ethereum.org/EIPS/eip-2935
• https://eips.ethereum.org/EIPS/eip-4788

Motivation

Access L1 state root on L2

Tasks

• Create design document that L1StateRoot Contract
• Present + discuss above design document

Acceptance criteria

• Discussion and consensus for smart contract implementation

Risks

• Taking too much time

Remember to

• Add the documentation label in case there is an impact on the documentation
• Add priority and team labels
• Add Task for updating the Runbook or adding/updating existing metrics and alerts.
