Solana is a high-performance Layer-1 designed for speed. By combining a Proof-of-History clock with Proof of Stake and a parallelized runtime (Sealevel), Solana processes thousands of transactions per second at sub-cent fees, making it the go-to chain for high-frequency trading, consumer apps and DePIN networks.
Unlike Ethereum's modular, rollup-centric approach, Solana is monolithic — execution, settlement and data availability all happen on one fast base layer. This delivers a seamless user experience but historically came with reliability trade-offs; the upcoming Firedancer validator client aims to harden the network.
SOL is the gas and staking token. Solana has become a center of gravity for memecoins, on-chain order-book DEXs, liquid staking and stablecoin payments, and consistently ranks among the top chains by active users and DEX volume.
