$SOL Solana was born in 2017, when Anatoly Yakovenko, a former Qualcomm engineer, presented the idea of a blockchain capable of processing thousands of transactions per second. His vision was to solve the scalability problems faced by other networks like Ethereum and Bitcoin. Yakovenko proposed Proof of History (PoH), an innovative system of cryptographic timestamps that allows for the efficient and fast ordering of transactions. In 2020, Solana launched its mainnet, attracting developers and DeFi, NFT, and Web3 projects. Since then, it has grown as one of the fastest and most promising blockchains within the crypto ecosystem.
