Sonic vs Sui

Sonic is an ultra‑fast EVM Layer‑1 claimed to reach 400k TPS and sub‑second finality via a custom SonicVM and DAG‑based consensus dubbed Tempo. Blocks are final once two‑thirds of stake attest, and state is stored in an in‑memory ledger that snapshots to disk every epoch. The project focuses on GameFi and real‑time social dApps, with an incentive testnet launched in May 2025.

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.
