Inspiration

The financial industry is transforming towards tokenized assets to improve the transparency and efficiency of financial instruments settlement. According to World Economic Forum’s report, the total market cap for tokenized assets is beyond $800+ trillion dollars. This transformation brings a tremendous opportunity for web3 to bridge web2 financial institutions to web3 infrastructure. Earlier this year, SWIFT and Chainlink CCIP achieved a pilot and it pointed out data security and privacy is NO.1 concern for web2 financial institutions to adopt web3. We aims to provide a Zero Trust Bridge on top of CCIP to empower security and privacy for across chain transactions and messages.

What it does

Our Zero Trust Bridge is built on top of a research innovation. We proposed and designed a Fully Homomorphic Encryption Due Key Stealth Address Protocol (FHE-DKSAP). It could be built on top of CCIP to make all cross-chain transactions more secure and privacy-preserving.

How we built it

We chose to build our demo on an existing POC from Chainlink CCIP and ANZ bank. We leveraged the API from CCIP and deployed our Zero Trust Bridge on top of it. It demonstrates how Zero Trust Bridge could work with CCIP to offer secure and privacy-preserving cross-chain transactions for ANZ or other financial institutions.

Challenges we ran into

The test net environment is quite unstable, which brought difficulties to test and deploy our solution. The mainnet is also not widely available at the moment, which may cause re-design and re-enginering. It also lack of documentation to understand how the existing solution (CCIP to ANZ) works.

Accomplishments that we're proud of

In such short period of time, we managed to understand the existing CCIP solution and built our innovative solution on top it. It could potentially solve a trillion dollar problem and transform the financial industry to the next stage.
