Solana (SOL) is a blockchain network created with the aim of conducting fast transactions. To enable fast transactions and increase scalability, Solana uses an interesting concept called Proof of History and combines it with the fundamental consensus of Proof-of-Stake. With this innovative hybrid consensus model, Solana seeks to provide a better infrastructure for creating a new generation of decentralized applications (Dapps). Proof-of-History is the main component of the Solana protocol. It is responsible for most transactions within a network. PoH records successfully completed transactions and the time elapsed between individual transactions. Proof-of-Stake, on the other hand, is used as a tool to track the Proof-of-History process and validate each subsequent block. Solana also has the original cryptocurrency SOL. Solana blockchain users need SOL to pay transaction fees. Users who hold (SOL) can also be network validators.
