Overview
Solana is a high-performance layer-1 blockchain known for fast transactions and low fees, using a proof-of-history clock combined with proof of stake. Launched in March 2020, it was designed to scale to thousands of transactions per second without sharding. Solana's native token is SOL, and it hosts a large ecosystem of DeFi, NFTs, and consumer applications.
How It Works
Solana's proof-of-history mechanism timestamps transactions before they are included, allowing validators to process them in parallel and finalize blocks in under a second. The network runs on proof of stake with a rotating set of validators, and its single global state makes composability straightforward. Its throughput depends on a fast, high-bandwidth network, which critics note can raise the hardware requirements for validators.
Why It Matters
Solana demonstrated that blockchains can deliver near-instant settlement and negligible fees, making it a popular choice for high-frequency trading, payments, and consumer apps. It has also experienced network outages, highlighting the difficulty of balancing performance with decentralization. As of 2026 it is one of the major ecosystems competing with Ethereum and its rollups.
