Solana is an open-source project that describes itself as a high-performance blockchain platform designed for hosting scalable decentralized applications and marketplaces.
It aims to process transactions quickly and at low cost by using a unique combination of proof-of-stake consensus and a novel mechanism called Proof of History for timestamping transactions.
Most people buy Solana on a major exchange. Binance has the lowest fees and the widest selection — here's the quick version:
SOL is the native cryptocurrency of the Solana network, used for paying transaction fees, participating in network security through staking, and interacting with applications built on Solana.
Solana combines Proof-of-Stake consensus with a cryptographic timestamping system called Proof of History, which helps the network process thousands of transactions per second very efficiently.
SOL can be obtained through cryptocurrency exchanges, by purchasing it directly, or by receiving it as payment for goods, services, or through staking rewards.
