Aptos vs Solana

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.

Solana combines Proof‑of‑History, Turbine block propagation and Gulf Stream forwarding to achieve throughput exceeding 50 000 TPS with 400 ms block times. The 2024 Firedancer client written in C++ reduced validator CPU requirements and added parallel pipeline execution. Solana Pay and the Saga phone SDK illustrate the project’s push toward consumer‑grade web3 applications.
