LayerZero says its in-house layer-one blockchain Zero is designed to horizontally scale beyond five million transactions per second, but the figure remains a theoretical target pending independent validation and public testing. The project, announced on February 10, 2026, uses parallel Atomicity Zones, separating transaction execution from verification through zero-knowledge proofs. Its architecture is intended to let lightweight Block Validators run on consumer-grade hardware while optional Block Producers handle more demanding work. LayerZero’s proprietary stack includes QMDB for state storage, FAFO for parallel computation, Jolt Pro for zero-knowledge proving and SVID for networking; the company says transaction costs are roughly $0.0001 each. Zero was initially reported to process about 200,000 TPS with latency below one millisecond, based on LayerZero’s own benchmarks. On August 25, 2026, LayerZero unveiled ATLAS, a headless exchange and cryptocurrency trading infrastructure on Zero. Citadel Securities, DTCC, ICE and Google Cloud were named as institutional partners, while Tether’s USDt0 stablecoin is already running on the infrastructure. ZRO rose approximately 20% after the ATLAS announcement, taking its market capitalization to around $746 million. The system is aimed at high-frequency trading and other latency-sensitive applications, but its practical significance will depend on whether it can deliver low fees, fast finality, security and decentralization at scale.
