Solana is a blockchain built for mass adoption. It's a high performance network that is utilized for a range of use cases, including finance, NFTs, payments, and gaming. Solana operates as a single global state machine, and is open, interoperable and decentralized. - Source: Solana Documentation

Solana Name Service (SNS) has a simple mission of providing a decentralized and affordable way to map domain names (represented as .sol) to on-chain data. Where on-chain data can be anything from a Solana (SOL) address to IPFS CID, images, text, and more. - Source: Solana Name Service
