Aptos vs MegaETH

Aptos is a Layer‑1 written in Rust that uses the Move language and AptosBFT v4—a Diem‑derived HotStuff variant—to finalise blocks in less than 1 second. Its Block‑STM executor runs transactions in parallel and abort‑reexecutes on conflict, achieving > 100k TPS in public benchmarks. The 2024 ‘Quorum Store’ upgrade optimised mempool sharding and reduced latency under network partition.

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.
