Proof of History (PoH) Definition - Glossary

Proof of History (PoH) is a cryptographic method that timestamps events, ensuring a verifiable sequence in blockchain networks.

Proof of History (PoH) is a consensus mechanism used primarily by the Solana blockchain. It creates a historical record that proves events have occurred in a specific sequence. PoH integrates timestamps into the blockchain, significantly improving network efficiency and scalability. Unlike traditional methods that require continuous consensus, PoH allows nodes to independently verify the order of events. This reduces the need for communication between nodes. By establishing a clear timeline, PoH enhances the speed and reliability of transactions, making it a valuable innovation in the blockchain space.
