The Global Legal Entity Identifier Foundation (GLEIF) announced the London Stock Exchange Group (LSEG) as the winner of its Global vLEI Hackathon in the Digital Asset and Financial Infrastructures category, selecting LSEG’s entry from 110 submissions. The winning solution illustrates how the Legal Entity Identifier (LEI) and verifiable LEI (vLEI) can support automated compliance, real-time auditability, and trusted digital transactions. Clearstream was named runner-up for applying the vLEI as a secure login standard for its ClearstreamXact platform, positioning organisational digital identity as a means to streamline access and improve operational efficiency. The hackathon, hosted during Chainlink’s SmartCon in New York, centred on how vLEI-based identity and authority verification can be embedded into digital ecosystems to strengthen trust and transparency in financial infrastructure.
