Solana: Proof of History – A Revolution in Blockchain Consensus! ⏳✨
The foundation of Solana's astonishing speed is its unique consensus mechanism — Proof of History (PoH). Unlike other blockchains where nodes spend time synchronizing clocks, PoH creates a historical record of events, proving that they occurred at a specific moment in time.
How it works: PoH is a cryptographic clock that enables validators to synchronize and quickly confirm transactions without the need to exchange timestamps.
Uniqueness: It is not a consensus mechanism in itself but a cryptographically verifiable order and timestamp for all events in the blockchain. It complements Proof of Stake (PoS), which Solana also uses.
Advantages: It eliminates delays associated with waiting for confirmations from other nodes, resulting in unprecedented throughput.
Proof of History is a key innovation that allows Solana to achieve the highest TPS rates and low latency.
