SOL

Solana is a Layer 1 blockchain launched in 2017 that prioritizes high throughput and low transaction costs through a novel technical architecture combining Proof of Stake consensus with Proof of History, a mechanism that timestamps transactions to function as a decentralized clock. The platform processes thousands of transactions per second with sub-second finality while maintaining costs typically below one cent per transaction, achieved without relying on sharding or layer-two solutions that could fragment liquidity. SOL, the network's native token, functions as the primary medium for transaction fees, network governance participation, and stake-based validation rewards. The Solana network employs the Sealevel runtime engine to execute non-conflicting smart contracts in parallel across multiple processor cores, and the Gulf Stream protocol further optimizes validation by forwarding pending transactions to validators before block completion. Since its inception, Solana has attracted substantial institutional support from venture capital firms like Andreessen Horowitz and Polychain Capital, as well as major partnerships including Visa's integration of USDC settlement and traditional asset tokenization initiatives by firms such as Galaxy Digital. The platform has become notable for supporting both decentralized application development and emerging use cases in institutional finance.
