Ronin vs Sui

Ronin is a delegated proof‑of‑authority sidechain built for gaming, best known for powering Axie Infinity. After the 2022 bridge exploit, Ronin migrated to a 17‑validator set with hardware‑signing requirements and added zkSync‑powered zkRonin bridges for withdrawals. The chain supports ERC‑721 and ERC‑1155 NFTs and charges near‑zero fees denominated in RON.

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.
