Solana (SOL) vs Sui (SUI)

Solana is a distributed and programmable layer 1 blockchain, part of the trend of "Ethereum Killers," which are competitors of Ethereum looking to replace it. Solana's unique design (notably through the Proof of History consensus) allows it to be optimized for scalability, with an exceptional (and theoretical) execution capacity of 60,000 transactions per second and extremely low fees. SOL is the native cryptocurrency of the Solana network, used to pay transaction fees, reward validators, and contribute to the governance of the project.

Sui is a layer 1 blockchain designed to host smart contracts and operates on a Delegated Proof of Stake (DPoS) consensus mechanism. Following the failure of Facebook's Diem project, some of the engineers came together to form Mysten Labs. The technology of Sui incorporates some technological innovations from the project, including the Move programming language and a modular and parallel architecture that allows for the simultaneous processing of a very large number of transactions.
