JPMorgan Adds Privacy Features to Ethereum-Based Quorum Blockchain


JPMorgan Chase’s blockchain team has developed a privacy feature for ethereum-based blockchains, obscuring not only how much money is being sent but who is sending it.
Revealed exclusively to CoinDesk, JPMorgan has built an extension to the Zether protocol, a fully decentralized, cryptographic protocol for confidential payments, compatible with ethereum and other smart contract platforms and designed to add a further layer of anonymity to transactions. The New York-based financial institution will open-source the extension Tuesday, and is likely to use it with Quorum, the bank’s homegrown, private version of ethereum.
Zether, which was built by a group of academics and financial technology researchers including Dan Boneh from Stanford University, uses zero-knowledge proofs (ZKPs), a branch of mathematics which allows one party to prove knowledge of some secret value or information without conveying any detail about that secret.
