$SOL is a digital currency based on blockchain technology, aiming to achieve fast and cheap settlement of transactions. It was launched in 2020 and has the ability to process up to 65,000 transactions per second, a number that far exceeds most other digital currencies. Solana relies on the Proof of History (PoH) consensus model to achieve this speed, as well as the Proof of Stake (PoS) consensus model to ensure security and decentralization. Solana also features a powerful development environment that allows creating innovative smart applications on the blockchain.
