Aptos vs ICP

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.

The Internet Computer (ICP) is a Layer‑1 that runs WebAssembly ‘canisters’ directly on chain, with sub‑second query calls and 2‑second update finality. Boundary nodes translate HTTP requests into signed chain queries, enabling dApps to serve web front‑ends without traditional servers. ICP’s reverse GAS model bills cycles in stable dollar terms, shielding developers from token volatility.
