Solana is a high-performance, decentralised blockchain platform designed to host fast, low-cost applications at global scale. Founded by Anatoly Yakovenko and Greg Fitzgerald in 2018 and launched publicly in 2020, Solana's core innovation is Proof of History (PoH), a timekeeping mechanism that dramatically reduces the time nodes need to agree on transaction order.
How Proof of History Works
Traditional blockchains require all nodes to communicate to agree on transaction sequence — a bottleneck at scale. Solana's Proof of History solves this by creating a cryptographic clock: a historical record that proves each transaction occurred at a specific moment. Because nodes can independently verify timing without constant communication, the network processes thousands of transactions per second without sacrificing decentralisation.
- Proof of History (PoH): the unique timestamp mechanism that orders transactions.
- Proof of Stake (PoS): validators stake SOL to participate in block production.
- Tower BFT: Solana's optimised Byzantine Fault Tolerance for fast finality.
- Turbine: a block propagation protocol that breaks data into smaller packets.
What Can You Do with SOL?
SOL, Solana's native cryptocurrency, serves two primary functions: paying transaction fees and staking to secure the network. Beyond these core uses, SOL is widely traded on cryptocurrency exchanges worldwide and used within Solana's growing ecosystem of DeFi protocols, NFT marketplaces, and gaming platforms.
The goal of Solana is to carry transactions as fast as news travels around the world.

Solana's Ecosystem
The Solana ecosystem spans DeFi, NFTs, gaming, and payments. Decentralised exchanges on Solana process billions of dollars in daily volume at fees that are a fraction of what Ethereum charges. Solana's inclusion in the Mastercard Crypto Partner Program marks a significant step toward mainstream commercial adoption.
- DeFi: lending, borrowing, and trading on decentralised Solana protocols.
- NFTs: low-cost minting and trading on Solana-based marketplaces.
- Gaming: high-throughput transactions ideal for blockchain-based games.
- Payments: Solana's speed and fees make it suitable for everyday transactions.
