LayerZero’s Zero blockchain architecture can now horizontally scale to five million transactions per second. The claim builds on a foundation the team has been laying since early 2026, when it first unveiled its heterogeneous L1 design capable of hitting two million TPS per individual “Atomicity Zone.”
The tech stack behind the numbers
Zero’s architecture separates transaction execution from verification using zero-knowledge proofs. The design allows lightweight Block Validators to run on consumer-grade hardware, while optional high-performance Block Producers handle the heavy lifting.
LayerZero built four proprietary components to make this work. QMDB handles state storage and can process up to 3 million updates per second. FAFO, the parallel computation engine, enables over 1.2 million EVM transactions per second on benchmark hardware. Jolt Pro manages ZK proving, and SVID handles networking.
Transaction costs sit at roughly $0.0001 per transaction.
