What consensus mechanism does Solana use?
Answer: Solana uses a unique consensus mechanism called Proof of History (PoH) combined with Proof of Stake (PoS). The Proof of History mechanism orders events in time without requiring a central clock. This allows the network to process transactions in parallel, increasing efficiency and scalability. Proof of Stake, on the other hand, ensures that the validators reaching consensus have a stake in the network, aligning their incentives with the network’s security and performance. By utilizing both mechanisms, Solana aims to achieve high transaction speeds and low costs, making it a competitive player in the blockchain space.
