Stellar vs Sui

Stellar is a payments‑focused blockchain that uses the Stellar Consensus Protocol (SCP), a federated Byzantine agreement where each node chooses its own quorum slices. Anchors issue fiat‑backed tokens, and Stellar’s built‑in DEX offers path payments that can hop through multiple assets in a single transaction. The 2023 Soroban upgrade added WebAssembly smart contracts, enabling on‑chain AMMs, lending and other DeFi primitives.

Sui employs an object‑based data model and Narwhal/Tusk DAG consensus to execute independent transactions in parallel, giving near‑instant finality. Programmability uses the Move‑based Sui language with object ownership, enabling upgrades without storage migrations. The network supports sponsored transactions, letting dApps pay gas on behalf of users—a boon for mobile onboarding.
