Aptos vs Manta

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.

Manta Pacific is a modular zk‑EVM Layer‑2 that stores rollup data on Celestia DA and uses universal circuits to keep prover costs low. Users can deploy privacy‑preserving smart contracts with built‑in zero‑knowledge widgets for shielding balances. The 2025 ‘Marlin’ release adds Account Abstraction and native bridges to Polkadot’s parachain ecosystem.
