Aptos vs Unichain

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.

Unichain is an OP‑Stack Layer‑2 built by Uniswap Labs that employs a trusted‑execution‑environment (TEE) block builder to guarantee ordered execution free from MEV. Liquidity pools enjoy baked‑in sandwich protection, and the UNI token governs sequencer whitelists. The chain inherited native hooks from upcoming Uniswap V4, enabling dynamic fee models.
