Cross-chain Governance

Cross-chain governance enables cross-chain voting and proposal creation for DAOs (tokens) on Ethereum through Clique. Clique will support cross-chain governance for Ethereum based projects and DAOs on the Polygon network.

The Cross-chain governance solution comes without the need for projects to issue new tokens or bridge existing tokens to the Polygon. The low gas fees are an advantage for DAOs implementing on-chain governance. Gas fees on Polygon are dramatically reduced compared to Ethereum for all governance activities, including voting and proposal creation.

Architecture of Cross-chain Governance on Polygon

On the Polygon, the governance contract allows users to create and vote on proposals. The voting power of a user is determined by the snapshot of their token holdings at the time a proposal is created.

The Data Bridge serves as a cross-chain synchronizer to communicate data and voting results between the DAO’s original chain (Ethereum) and Polygon chain. The data bridge caches historical data and snapshots from Ethereum as a certificate in order to deliver user signatures on Polygon. The certificate includes the corresponding token holdings of each user. Users can create and vote on proposals using their signature, with each unique signature being validated by the contract.
