Solana adopts a hybrid consensus mechanism of Proof of History (PoH) and Proof of Stake (PoS). PoH can determine the transaction order and global clock, which is beneficial to improving the block generation efficiency. This innovative consensus mechanism enables Solana to have better scalability and performance, and can better cope with the situation of a large number of users and transactions, providing a technical guarantee for its long - term development, and is one of the important factors attracting investment.
