Solana (SOL) is a high-performance blockchain designed for speed, scalability, and low-cost transactions. Unlike traditional proof-of-work systems, Solana uses a unique consensus mechanism called Proof of History (PoH) combined with Proof of Stake (PoS), enabling it to process tens of thousands of transactions per second with minimal fees. Its ecosystem supports a wide range of applications, including DeFi, NFTs, gaming, and decentralized infrastructure. Solana's fast-growing developer community continues to build innovative tools and apps, while upcoming upgrades like the Firedancer validator client aim to further boost performance and reliability. With increasing institutional interest and real-world adoption, Solana is emerging as a serious contender in the crypto space.
