Solana is a high-performance blockchain known for its fast transaction throughput and low fees. It uses a unique proof-of-history (PoH) mechanism in combination with proof-of-stake (PoS) to process thousands of transactions per second, making it an attractive platform for decentralized applications (dApps), DeFi protocols, and NFT marketplaces. Solana's architecture enables scalability and is optimized for high-speed decentralized finance and crypto projects.
