LayerZero and 21X Pilot On-Chain Order Book Achieving 10,000 Matches Per Second

The interoperability protocol LayerZero and the European digital asset trading venue 21X have announced the successful completion of a month-long pilot program focused on institutional-grade on-chain trading. Utilizing a private permissioned instance of the Zero blockchain, the partners demonstrated the viability of a fully decentralized central limit order book (CLOB) capable of matching 10,000 orders per second. This milestone represents a significant advancement in the scalability of Ethereum Virtual Machine (EVM) compatible environments for traditional financial applications.

High-Performance Trading on the Zero Blockchain

The pilot program focused on the trading and settlement of tokenized US equities, conducting all matching processes directly on-chain without the use of off-chain matching engines. By leveraging the Zero blockchain—an infrastructure previously announced in collaboration with major financial entities such as Citadel Securities, DTCC, ARK Invest, and the Intercontinental Exchange (ICE)—the system achieved a performance increase of approximately 45 times over the standard institutional EVM baseline.

The technical success of the trial was underscored by several key features:

• The integration of matching and settlement within the same transaction, reducing counterparty risk.
• Achievement of 10,000 matches per second, rivaling the performance of traditional centralized exchanges.
• The use of a permissioned DLT environment to ensure compliance with institutional regulatory requirements.

Regulatory Compliance and the DLT Pilot Regime

As a licensed trading and settlement venue, 21X operates under the European Union's DLT Pilot Regime, a framework designed to foster the development of distributed ledger technology in financial markets. The DLT Pilot Regime provides a regulatory sandbox for firms to test blockchain-based market infrastructures for financial instruments such as shares and bonds. This institutional-grade environment allows for the exploration of on-chain order books while adhering to strict security and transparency standards required by global regulators.

The collaboration illustrates a growing trend where traditional market participants utilize blockchain-based settlement layers to improve capital efficiency. By removing the need for off-chain reconciliation and ensuring that trades are finalized the moment they are matched, the pilot demonstrates a path toward a more streamlined global financial system.

This successful test on the Zero network marks a pivotal step for LayerZero in its efforts to bridge the gap between decentralized protocols and traditional finance. As the industry moves toward the widespread adoption of Real-World Assets (RWA), the ability to handle high-frequency trading volumes on-chain remains a critical prerequisite for mass institutional migration to blockchain networks.
