Stellar (XLM) vs Sui (SUI)

Stellar is a layer 1 blockchain platform designed to support fast, secure, and low-cost value transfers between different currencies. Launched in 2014 by one of the co-founders of Ripple, another cryptocurrency project aimed at facilitating cross-border payments for businesses and institutions, Stellar focuses more on modest daily exchanges. The Stellar network uses a unique consensus protocol, the Stellar Consensus Protocol (SCP), which allows for rapid transaction confirmation without relying on Proof of Work (PoW) or Proof of Stake (PoS).

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.
