Solana (SOL) is a digital currency and blockchain project that is considered one of the most prominent currencies in the crypto world due to its high speed and low transaction costs. It was launched in 2020 and aims to provide a decentralized platform that supports smart contracts and decentralized applications (dApps) in a way that surpasses many competitors like Ethereum in terms of performance.

Solana relies on a unique mechanism called "Proof of History" along with "Proof of Stake," which allows it to process thousands of transactions per second. It is used in various fields such as decentralized finance (DeFi), gaming, NFTs, and Web3 applications. The SOL token is used as a means of payment within the network and to pay transaction fees, and it can also be staked to earn rewards.

Thanks to its strong infrastructure and increasing partnerships, Solana has become a focal point for developers and investors, and despite some technical challenges it faced in the past, it still maintains a strong position in the market.
