Cardano (ADA) vs Sui (SUI)

Cardano is an open-source, programmable layer 1 blockchain, with a technological approach based on scientific and academic research. The network operates on a Proof of Stake (PoS) mechanism, and the native cryptocurrency, ADA, is used by node operators or delegators to contribute to block design and security.

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.
