Proof of Proof (PoP)™ enables blockchains to inherit the proof of work security of Bitcoin (or another blockchain) in a decentralized, trustless, permissionless, and transparent manner. PoP™ introduces a new form of mining—PoP™ mining—which involves the publication of the blockchain’s current state to Bitcoin. PoP™ can be implemented on a proof of work (PoW), proof of stake (PoS), and hybrid consensus blockchains. By utilizing the timely publication of blockchain state data when resolving forks, exchanges and merchants benefit from early detection of potential attacks on a blockchain’s consensus.
