Solana is a high-performance blockchain designed to support scalable decentralized applications (dApps). It combines Proof of History (PoH) with Proof of Stake (PoS) to improve transaction ordering and network efficiency, with block times of around 400 milliseconds and high throughput under optimal conditions.

Solana is known for its fast transactions and relatively low fees, supporting use cases in DeFi, NFTs, gaming, and Web3 applications. The network is secured by validators who stake SOL tokens, helping maintain security and network stability.
