PoH (Proof of History)

Proof-of-History (PoH) is a consensus mechanism used in Solana blockchain. It timestamps transactions cryptographically, creating an immutable sequence of events. PoH enhances scalability and efficiency by eliminating the need for extensive computational resources in verifying transactions. This mechanism allows for fast transaction processing and confirmation, increasing throughput and reducing latency. Validators reference the PoH sequence to efficiently verify transactions, maintaining the security and integrity of the blockchain. PoH enables Solana to scale effectively, accommodating a higher volume of transactions without compromising performance, making it suitable for real-world applications requiring fast and reliable transaction processing.
