Solana ($SOL ) is a high-performance blockchain designed for decentralized applications (DApps) and crypto projects. Launched in 2020, it utilizes a unique **Proof-of-History (PoH)** mechanism combined with **Proof-of-Stake (PoS)** to achieve fast transaction speeds and low costs. Solana supports smart contracts, making it a strong competitor to Ethereum in DeFi and NFT markets. Its ecosystem includes decentralized exchanges, gaming platforms, and Web3 applications. Despite occasional network outages, Solana remains a top blockchain due to its scalability and developer-friendly environment. The native token, SOL, is used for transaction fees, staking, and governance, contributing to its growing adoption in the crypto space.
