Solana Proof of History

Algorithm

Solana Proof of History (PoH) represents a novel cryptographic clock designed to provide a verifiable ordering of events without relying on traditional blockchain consensus mechanisms. It achieves this by generating a single, continuously running hash chain, where each block’s hash incorporates the previous block’s hash and a timestamp. This allows for efficient verification of the order and timing of transactions, significantly reducing the computational overhead associated with achieving consensus. Consequently, PoH enables Solana to process transactions at a substantially higher rate compared to blockchains that depend on more computationally intensive consensus protocols.
