A » Proof of History (PoH) is a cryptographic innovation used by the Solana blockchain to establish a historical record that verifies the sequence and time of events. Unlike traditional consensus mechanisms, PoH creates a verifiable passage of time between transactions, improving efficiency and scalability by enabling nodes to agree on the order of events without extensive communication, which accelerates transaction processing and reduces latency.
