LayerZero Labs, the team behind the widely used cross-chain messaging protocol, unveiled Zero, a new heterogeneous Layer-1 blockchain architecture on February 10, 2026. The architecture uses zero-knowledge proofs to decouple transaction execution from verification, splitting validators into two roles: lightweight Block Validators that handle verification, and optional high-performance Block Producers that handle execution. The verification layer stays decentralized and accessible. The execution layer scales horizontally through parallel Atomicity Zones.
The performance targets are eye-catching. LayerZero is claiming up to 2 million transactions per second per “Atomicity Zone,” with horizontal scaling potentially pushing that figure to 5 million TPS. Transaction costs sit at roughly $0.0001. For context, Ethereum’s mainnet processes around 15-30 TPS on a good day, and even Solana’s theoretical maximum hovers around 65,000 TPS.
How Zero actually works
Each Atomicity Zone functions as its own specialized environment. Rather than competing for block space on a single chain, different use cases get their own lanes. ZK proofs allow the network to confirm transactions are valid without requiring every node to re-execute them.
