Introducing Quick Merkle Database (QMDB), a high-performance verifiable database optimized for blockchains. • 2.28M state updates per second, 1M TPS (benchmarked transfers per second). • Benchmarked with workloads up to 15B (10x Ethereum’s 2024 state) and proven capacity to scale to 280B entries on a single server. • Single read per state access, O(1) I/O for updates, and in-memory Merkleization on a footprint as small as 2.3 bytes per entry. • Efficiently scales across both consumer grade and enterprise hardware. Developed by LayerZero Labs, QMDB is MIT and apache-2 licensed and completely open-source.
