LayerZero announced the launch of the Quick Merkle Database (QMDB), a high-performance, verifiable database optimized for blockchain. Developed by LayerZero Labs under the MIT and Apache-2 licenses, QMDB is fully open-source. 2.28 million status updates per second 1 million TPS (base transfer per second). Benchmark workloads to 15 billion (10 times the 2024 state of Ethereum) and prove to scale to 280 billion records on a single server. Each state accesses a single read, with an I/O of O (1) for updates, and in-memory merkling at 2.3 bytes per record storage footprint. It can be efficiently scaled on both consumer and enterprise-grade hardware.
