MegaETH vs Sonic

MegaETH is an Ethereum Layer-2 designed as a real-time blockchain, with documentation highlighting roughly 10 ms block times and real-time transaction processing. It keeps the EVM developer surface while redesigning execution, mini-blocks and settlement around low-latency applications. The network uses chain ID 4326 and has MEGA as its associated CoinGecko token.

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.
