ZK-proofs ‘Particularly Relevant in Financial Services’: Google Cloud Web3 Lead
On-chain privacy-preserving applied sciences corresponding to zero-knowledge proofs have purposes in fields corresponding to monetary providers and healthcare, in keeping with Google Cloud’s Head Of Web3 Engineering.
Talking at CCDAS 2023, James Tromans referred to as ZK-proofs “significantly related in monetary providers and Web3 extra broadly,” including that, “the thought that you will put choice contracts on-chain and have the counterparties and the strike value and the notional so forth, seen to everyone is unnecessary.”
Zero-knowledge proofs are a cryptographic method used to show that one thing is understood, with out exposing the identified data.
The know-how has turn into a spotlight of efforts to spice up on-chain privateness; Ethereum co-founder Vitalik Buterin not too long ago co-authored a paper exploring how ZK-proofs could possibly be utilized to a privacy-preserving blockchain protocol that balances person anonymity with the necessity for regulatory compliance.
“If we will dwell in a world the place we put these kinds of offers on-chain—and never on a centralized alternate which has the duty of preserving that data secure and personal—then we will want further privacy-preserving applied sciences that maybe aren’t in manufacturing at scale getting used right this moment to resolve these issues,” Tromans mentioned. ZK-proofs, he added, “could also be one technique to obtain that.”
What are Zero Information Proofs?

At CCDAS, Google Cloud’s Tromans argued that ZK-proofs and different on-chain privateness applied sciences may have purposes in fields corresponding to healthcare.
“I believe that is related in different industries, the place plenty of the funding we have seen come into Web3 for the previous few years—and clearly, a lot of that has shifted to AI not too long ago—will bear fruit that is not simply this hypothesis on token costs,” he mentioned, pointing to applied sciences together with ZK-proofs and multi-party computation.

Such applied sciences, Tromans famous, have wider applicability past blockchain. “We’ll see them in use in different places, and that is going so as to add worth,” he mentioned. “So for me, Web3 is far more than simply blockchain and decentralization of knowledge.”
Nonetheless, he cautioned that the oft-touted Web3 idea of customers proudly owning their very own information could also be overstated.
“I do not imagine we will all of the sudden see that companies will not maintain your information,” he mentioned, including, “Placing apart zero-knowledge proofs, we’re nonetheless going to wish to share our information with the companies that we do enterprise with.” If companies provide “a terrific service and [are] including worth, prospects will wish to give them their information,” he mentioned.
Extra broadly, Tromans added, Web3 adoption nonetheless has an extended technique to go, likening it to the “arduous and nonetheless ongoing” transition of enormous organizations to the general public cloud.
“We’re speaking about one thing that is even much less clear to those organizations, about how Web3 and blockchain will work for them,” he mentioned. “They don’t seem to be going to make that transition and simply down instruments on what they had been doing earlier than—except they will notice new income streams and get entry to new issues that they weren’t doing earlier than.”
