Chainlink, an oracle platform, has completed the second phase of an industry initiative to standardise and streamline corporate actions processing using a combination of the firm’s platform, blockchain technology, and AI.
The Chainlink-powered solution allows organisations to get structured and validated corporate actions data efficiently across multiple languages directly into their existing systems.
The banking and capital markets industry initiative has expanded to 24 global organisations, including financial and market infrastructures such as the Depository Trust & Clearing Corporation (DTCC), Swift, and Euroclear.
It also involves asset managers and banks such as UBS, DBS Bank, BNP Paribas’ Securities Services business, and ANZ.
In phase 1 of the initiative, Chainlink, Swift, Euroclear, and six financial institutions demonstrated that large language models (LLMs) — such as OpenAI’s GPT series, Google’s Gemini series, and Anthropic’s Claude series — could extract structured data from unstructured corporate action announcements.
It showed LLMs could publish it as unified golden records on-chain — a single source of information that all participants can access, verify, and build upon.
Phase 2 presented a production-grade arrangement by making improvements to the speed, reach, and accessibility of corporate actions data.
The Chainlink Runtime Environment (CRE) arranged the validation of several AI model outputs and transformed the confirmed results into the ISO 20022-compliant messages which were then transmitted to the Swift network.
Simultaneously, Chainlin’s Cross-Chain Interoperability Protocol (CCIP) distributed these confirmed records across DTCC’s blockchain ecosystem and additional public and private blockchain environment, allowing concurrent access across conventional infrastructure and blockchain-based platforms.
The system attained almost 100 per cent data consensus agreement among AI models across all evaluated corporate actions during the testing.
The solution opens up a unified golden record for corporate actions, a real-time source of truth that can be accessed concurrently by smart contracts, custodians, and post-trade systems.
It also enables tokenised equities, an increasingly adopted category of tokenised assets, to reference the same confirmed records across public and private blockchains, the firm says.
Sergey Nazarov, co-founder of Chainlink, says: “I am very excited about our collaboration with Swift, DTCC, Euroclear, UBS, DBS, and many other leading financial institutions on solving corporate actions on-chain, a problem that has to be solved in order for tokenised public equity to scale up and work correctly on-chain.
“Being able to solve the data validation problem of corporate actions using AI Oracle Networks from Chainlink is a big leap forward in what AI Oracle Networks are capable of, showing that multiple AIs can come to consensus on critical information inside of a decentralised oracle network.
“Placing this AI consensus-validated corporate actions record on-chain and across chains using CCIP is a huge step forward for how corporate actions can work across the capital markets.”
