Aptos vs Ink

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.

Ink is Kraken's Ethereum OP Stack Layer-2 built as a DeFi-focused member of the Optimism Superchain. It offers EVM compatibility, low fees and one-second blocks from launch, with sub-second blocks planned, so builders can deploy lending, DEX and yield applications close to Kraken's user base. No dedicated Ink token is mapped yet, so the blockchain is imported without an associated token.
