  • This document seeks to describe a Proof of Consensus that is composed of different Proofs of Consensus for the Gasper protocol. The motivation behind this is because all the different Proof of Consensus protocols have varying tradeoffs that are different between them. There is an assumption that the reader already has a very basic understanding of Proof of Consensus, Fault Proofs, and ZKP. Proof of Consensus Properties Bridges today can be catagorized by many different properties. The main properies that are important for DPoC are trustless, speed, cost, and permissionless. To establish common ground, let establish rough definitions of these properties: Trustless describes someones ability to verify the validity of the state of the system. Trustless-ness can be described on a spectrum, ranging from fully trustful to partially trustful to optimistically trustless to fully trustless. Speed describes how long it takes for someone to decide that some cross chain interaction will not reverted. This is can be very context dependant according to the users risk profile and will be examined more when investigating and catagorizing existing Proof of Consensus protocols. Cost describes how much it takes to maintain the Proof of Consensus protocol.
