2 Million TPS Without Centralization? How LayerZero Labs Says It Has Cracked Scalability

LayerZero Labs introduces Zero, a new blockchain aiming for two million transactions per second without centralization by leveraging a novel storage layer (QMDB), efficient execution (FAFO), and ZK compression to support global permissionless markets and payments at scale.

• Zero blockchain aims for 2M TPS at low cost while maintaining decentralization through novel tech.

• Key innovations include QMDB storage, FAFO execution, network compression, and ZK proofs for compute.

• LayerZero Labs is partnering with major institutions to drive real-world adoption in global markets and payments.

LayerZero Labs is launching a new blockchain called Zero, designed to achieve unprecedented scalability—up to two million transactions per second—while maintaining decentralization. This breakthrough addresses the limitations of existing blockchain scaling approaches that either centralize or fall short on transaction capacity. Zero achieves this through innovations in its storage layer, execution, networking, and the use of ZK proofs for compute compression rather than just privacy.

Zero Blockchain Introduction

• 00:02:41 LayerZero, originally a messaging protocol, is launching a new blockchain called Zero to address the critical problem of scalability in the blockchain space. The core issue identified is the replication cost, where every node re-executes the same compute, making systems expensive and inefficient. Zero aims to overcome this by introducing four 100x breakthroughs in storage, compute, network, and ZK technology, enabling up to two million transactions per second (TPS) per zone at a cost of 1/10,000th of a penny per transaction and supporting execution across any virtual machine or Linux binary.

Scaling Without Centralization

• 00:05:07 Existing scaling solutions either lead to centralization (like Solana's high node requirements) or rely on Layer 2s that introduce centralized trust assumptions (like Ethereum's scaling roadmap). LayerZero Labs developed Zero to achieve decentralized, permissionless, and censorship-resistant systems that scale to millions of nodes and millions of transactions per second. The fundamental problem of replication cost is tackled by generating a single proof for computation, which all nodes can then efficiently verify, removing the need for every node to re-execute the same work.

Technical Breakthroughs of Zero

• 00:07:37 Zero's scalability is built upon four key technical breakthroughs. First, 'QMDB' is a log-based database that is 100x more performant than previous verifiable databases, enabling three million updates per second. Second, 'FAFO' unlocks execution efficiency, allowing a single node to achieve one million TPS with the EVM overhead, addressing the misconception that EVM is inherently slow. The other breakthroughs include 'SVID' for network data compression and ZK proofs for compute compression, where computations are run once, a proof is generated, and nodes only need to verify the proof, making verification effectively free relative to computation.

Strategic Institutional Partnerships

• 00:17:21 Zero is strategically partnering with major traditional finance institutions like Citadel Securities, DTCC, and Intercontinental Exchange, along with investors like Tether, to co-build and facilitate real-world adoption. The blockchain is designed with a beacon chain architecture supporting multiple application 'zones' for general-purpose smart contracts, global markets, and payments. These partnerships leverage the institutions' expertise and address the demand for permissionless global markets, capable of operating 24/7 across various asset classes, which current centralized systems struggle to meet.
