The Pause Guardian is emergency functionality used to pause supply, borrowing, or liquidation in a market.
This proposal transfers guardianship from Compound Labs (which has always held this role) to Community Multi-Sig created by members of the community: 0xbbf3f1421D886E9b2c5D716B5192aC998af2012c.
The Multi-Sig requires 4-of-6 signers to approve any transaction. The signer addresses can be seen here on Gnosis Safe, and currently include @TennisBowling, @arr00, @blck, Compound Labs, Dharma Labs (@0age), and @jared. For full context and history on the Multi-Sig, please see this post on the Compound Community Forum.
Setting the Pause Guardian address to the Community Multi-Sig will further decentralize and ensure the security of the Compound Protocol.
