decentralized and scalable. Its architecture is based on an innovative mechanism called Proof of History (PoH), combined with Proof of Stake (PoS), which enables high transaction speeds (up to 65,000 TPS) at low costs. Launched in 2020, Solana attracts a growing ecosystem of DeFi, NFT, and Web3 projects. Despite past network outages, it remains a serious alternative to Ethereum in terms of scalability. Its native token, SOL, is used for staking and paying transaction fees.
