Chainlink launches private blockchain transactions for institutions

As a seasoned crypto investor with over a decade of experience in the digital assets market, I have seen my fair share of promising technologies that didn’t quite deliver. However, I must admit that Chainlink’s latest privacy-focused developments for financial institutions have caught my attention.


Chainlink, a decentralized oracle network built on the Ethereum blockchain, recently introduced innovative tech aimed at ensuring financial institutions can securely exchange data without compromising privacy when dealing with various blockchain systems.

On October 22nd, Chainlink unveiled two novel, privacy-focused functionalities tailored for financial institutions seeking to utilize blockchain applications without compromising full end-to-end confidentiality.

The newly launched privacy features include the Blockchain Privacy Manager, which enables private chain integration with the public Chainlink Platform and an encryption protocol called CCIP Private Transactions.

ANZ Bank to debut the tech for RWAs

Australian-New Zealand Banking Group (ANZ Bank) is set to be among the pioneers testing Chainlink’s privacy-focused functionalities.

ANZ Bank plans to incorporate technology that facilitates cross-chain transactions for tokens representing real-world assets (RWA), in line with the tokenization project led by the Monetary Authority of Singapore, known as Project Guardian.

As a researcher, I’m excited about the potential applications of Chainlink’s latest innovation, the Blockchain Privacy Manager. This tool will allow institutions such as ANZ Bank to seamlessly connect their private blockchain networks with other public and private blockchains via the Chainlink CCIP network. Moreover, it provides a means for integrating traditional finance and enterprise systems with private blockchains through the Chainlink platform, as per the recent announcement.

In simpler terms, using CCIP Private Transactions enables financial institutions to securely encode and decode sensitive information like transaction values and parties involved, as they carry out transactions that span several private blockchains.

According to Chainlink, their latest privacy features empower institutional users to establish privacy rules such that only authorized parties involved in a transaction or from the compliance sector can access the on-chain data, while keeping it concealed from all external entities and potential threats.

Why do institutions need private blockchain transactions?

As a crypto investor, I’ve noticed that the absence of robust, cross-chain privacy mechanisms has been posing a challenge for financial institutions in securely interacting across various blockchains. This is because many regulations, like the GDPR in Europe, demand stringent data protection standards. Chainlink highlights this issue, emphasizing that addressing it is crucial for seamless and compliant multi-blockchain transactions.

To comply with GDPR regulations, institutions must make sure that all data is protected from start to finish in private chain-to-private chain transfers and minimize the amount of data shared in private chain-to-public chain interactions.

Sergey Nazarov, co-founder of Chainlink, emphasized that privacy is essential for most institutional dealings. He anticipates a surge in institutional use of blockchain technology due to Chainlink’s capability to facilitate private transactions across various networks.

“We are excited to continue our collaboration with ANZ and explore how to make large transactions across multiple chains in a way that helps meet their compliance and legal requirements […].”
