Aptos vs Katana

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.

Katana is a DeFi Layer-1 chain incubated by Polygon Labs and GSR, designed to maximize on-chain liquidity and real yield. Its Vaultbridge system redeploys bridged assets like ETH and USDC into yield strategies on Ethereum, while Chain-owned Liquidity (CoL) channels 100% of sequencer fees into deep, protocol-controlled liquidity pools. Katana’s native AUSD stablecoin, backed by US Treasuries, powers lending markets and DEX liquidity with off-chain yield incentives.
