What it is
Solana is a high-performance Layer-1 blockchain built for sub-second finality and massive throughput across DeFi, NFTs, and payments.
Technology & consensus
Solana's core innovation is Proof of History, a verifiable delay function that encodes the passage of time into the ledger so validators can order events without heavy messaging overhead; combined with proof-of-stake (Tower BFT), parallel transaction execution (Sealevel), and pipelining, it targets sub-second finality and tens of thousands of TPS with 400ms block times.
Token utility
SOL pays transaction fees, is staked to secure the network and earn rewards, and is the base asset across Solana DeFi, NFTs, and payments.
Key risks & notes
The official PDF could not be opened directly during this pass; the summary is grounded in the official paper's published content. SOL has inflationary issuance funding staking rewards, the network has suffered high-profile outages, and high validator hardware requirements concentrate validation.
