Chainlink has launched CCIP Private Transactions, a new privacy-preserving feature powered by blockchain technology, which aims to enable financial institutions to maintain data privacy, integrity and regulatory compliance when conducting cross-chain transactions. In its announcement, Chainlink said the development addresses pressing privacy concerns that have thus far limited institutions’ participation in blockchain ecosystems due to the need for secure, private transactions.
An early adopter of the technology is the Australia and New Zealand Banking Group (ANZ), which will test the capability as part of the Monetary Authority of Singapore’s (MAS) Project Guardian. The project focuses on the cross-chain settlement of tokenized real-world assets (RWAs), highlighting a use case that complies with regulatory standards such as GDPR and MiFID II.
Previously, financial institutions were reluctant to engage with blockchain due to the lack of privacy solutions for cross-chain transactions. The rules require end-to-end privacy for interactions between private blockchains, as well as limited data disclosure when transactions involve public blockchains. Chainlink said its CCIP Private Transactions aims to address this issue by providing a new encryption and decryption protocol that keeps transaction details private, including data, token amounts and counterparties involved.
