Solana (SOL) is a high-performance, open-source blockchain platform built for scalable and decentralized applications and cryptocurrencies. Solana's main advantage is its ability to process up to 65,000 transactions per second thanks to its unique combination of Proof of History (PoH) and Proof of Stake (PoS) consensus algorithms, which provides high speed and low fees. The platform supports smart contracts and decentralized applications (dApps), which makes it attractive to developers and investors. The SOL cryptocurrency is used to pay for transactions and staking on the Solana network, providing security and encouraging participation in the ecosystem.
