$BTC Solana - is a smart contract platform that uses electronic signature methods based on public and private keys to ensure the security and trust of the parties to the contract. It operates on blockchain technologies that eliminate human factors in transaction execution. Solana provides decentralization of the smart contract execution environment, making it similar to platforms like Ethereum and Codius. Additionally, Solana employs a proof of stake (PoS) algorithm for consensus and verification among cryptocurrency holders, distinguishing it from cryptocurrencies that use proof of work (PoW).[1][2]
