Avalanche vs Sui

Avalanche implements Snowman consensus on its C‑Chain (EVM) and runs a multi‑chain architecture with X‑Chain (UTXO) and P‑Chain (staking). Custom subnets allow projects like DeFi Kingdoms and Intain RWA to spin up their own validator sets with whitelisted tokens. The 2025 Banff hard fork added elastic subnets with dynamic validator staking for improved security sharing.

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.
