The centralized finance stalwart is working with Horizen, a platform that develops and maintains the privacy token ZEN, to take a look at creating a proof-of-reserves system using Horizen's zero-knowledge proofs.

"The biggest challenge in DeFi is transparency," said Nuke Goldstein, chief technology officer at Celsius.

The proof-of-reserves pilot would take the information that appears on Celsius' website and have it fed from a Horizen sidechain as opposed to Celsius' internal servers.

The application would show total customer assets per coin type at first and eventually share Celsius transaction data encrypted by Horizen's zero-knowledge-proof toolkit so as to not reveal the personally identifiable information of customers.

That said, the proof of reserves wouldn't give customers a look into what portion of Celsius' lending portfolio is unsecured; what portion of depositors' funds have been invested in derivatives contracts rather than in loans; or the amount of collateral pledged by borrowers that is being rehypothecated by Celsius.

Nic Carter, co-founder of Castle Island Ventures and Coin Metrics, has written extensively about proof of reserves and is advocating for every crypto custody firm to adopt the transparency measure.

"Because I've never seen a proof of reserves for a lender before, it's difficult to conceptualize what they're trying to do," Carter said via email.

Celsius failed to provide a wireframe of the concept.

Celsius will also subject these proofs-of-concept to hackathons in the Celsius community.
