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), Proof-of-Capacity (PoC), 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.
