Governor Interop Design Document

[corydickson]

Description

This document outlines changes to the Governor contract to support interop voting. With the additional changes and considerations outlined from @skeletor-spaceman and other members that include possible alternative solutions.

[gotzenx]

After talking with different stakeholders we have proposed a new and simpler path as the first version of GovToken that should respect the following points:

• We will only make one and only upgrade to the OP Token to make it interoperable.
• This MVP version should only move the current delegation logic to an external contract separated from the token contract.
• Delegation contract needs to be compatible to be upgraded into it's interop evolution.
• Interop governance will not be part of this MPV.
• No change is required in snapshot key now.
• Delegation and Voting will only happen on OP-mainnet for now.
• Nothing from future iterations must force a token upgrade.

Any extra features like partial-delegation or interop-delegation are not a priority right now and will happen on future iterations after the token upgrade.

This current design doc aligns with the interop-governance version that will come after the MVP.
So we suggest to have a new doc (or modify this one) that reflects the MVP version, and keep this one as a future version.

Just got off a call between Agora <> Wonderland and we've got some news and a great path forward.

Decision 👩‍⚖️: Focus on Interop Gov Token for liquidity unlock and single chain governance with a separate delegation contract to keep upgrades easier. This will allow Governance to function well and de-risk any token upgrade work.

Plan

Step 1: Ship Interop Gov Token and make sure it's compatible with single chain, OP Mainnet Governance as the V1 for Devnet 2 in 2024.
Step 2: Kick-off more in depth design sessions around how to bring Interop Governance to OP in Q4 2024
Step 3: Ship Interop with Single Chain Governance to OP Mainnet to get the liduidty unlock that @K-Ho / Zain did such a good job pitching last week
Step 4: Build and ship Interop Multi-chain Governance in 2025

Pros

Simpler rollout for 2024
More time to consider complex multichain governance architectures without holding up token upgrade
One token upgrade

Cons:

Takes us a bit longer to get to the multi-chain governance promise land but gives us more time to measure twice and cut once and bring in more governance stakeholders.

Division of labour:

Interop Gov Token & Token Upgrade Logistics -> Wonderland
External Delegation Contract, Updated Governor, Support for Partial Delegation -> Agora

We will be tightly collaborating and reviewing each others specs / implementation so that we can land the plane together.

Next actions on this PR

@gotzenx + @corydickson + @cairoeth -> let's keep this one open and then we can come back to it.

We will also create docs for:

• GovernanceDelegation Contract
• OP Governor w/ Interop Token and External GovernanceDelegation
