Selected from over 110 global submissions, LSEG’s winning solution showcased how the Legal Entity Identifier (LEI) and verifiable LEI (vLEI) can be integrated into crypto and digital asset frameworks to enable automated compliance and real-time auditing. By embedding trust at the protocol level, the innovation supports a future where institutional blockchain transactions are verifiable and regulator-ready.

Embedding digital trust in blockchain systems

The vLEI system, a next-generation digital identity framework, provides verifiable proof of organizational identity and authority — a critical need as crypto markets mature under tighter oversight. LSEG’s implementation demonstrates how decentralized systems can interoperate with traditional financial infrastructure while maintaining auditability and compliance.

Clearstream, the hackathon’s runner-up, was recognized for developing a secure login model using vLEI on its ClearstreamXact platform, showing how regulated institutions can streamline user verification and reduce operational risk through cryptographic identity tools.

Driving regulated innovation in crypto finance

Hosted during Chainlink’s SmartCon in New York, the GLEIF Hackathon underscored the growing convergence of blockchain, regulatory technology, and digital identity. As institutions move toward tokenized securities and on-chain financial operations, vLEI-based identity standards are emerging as the backbone for trusted digital asset ecosystems.

The event reinforced GLEIF’s commitment to building a globally interoperable framework that supports the secure exchange of digital assets and institutional-grade blockchain finance.

Meanwhile, Deutsche Börse Market Data + Services has also announced a strategic partnership with Chainlink to deliver real-time multi-asset market data from Eurex, Xetra, and Tradegate directly on-chain — further reinforcing the shift toward verifiable, blockchain-based financial information. The initiative marks a breakthrough in bridging traditional finance and blockchain-based systems.
