$SOL Solana (SOL) is a digital currency and blockchain platform aimed at achieving high transaction speeds and low fees. Solana uses a Proof of History (PoH) mechanism in addition to Proof of Stake (PoS) to achieve this. Solana is known for decentralized finance (DeFi) applications and non-fungible tokens (NFTs).

Solana features several advantages, including:

* Speed: Solana can process thousands of transactions per second, making it much faster than many other blockchain platforms.

* Low fees: Solana's transaction fees are very low, making it an attractive option for users who want to make small transactions.

* Scalability: Solana is designed to be scalable, meaning it can handle a large number of transactions without sacrificing speed or fees.

However, Solana has also faced some challenges, including occasional network outages.
