Sui vs Tezos

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.

Tezos is a self‑amending Proof‑of‑Stake Layer‑1 that supports on‑chain governance, letting token holders adopt protocol upgrades without hard forks. Its latest ‘Mumbai’ upgrade activated Smart Rollups, allowing scalable L2s written in Rust and Wasm to inherit Tezos security. Tezos processes ~1 million contract calls daily and is popular for compliant tokenisation of securities in Europe.
