Binance reserves proof 'pointless without commitments': Kraken CEO

The FTX cryptocurrency exchange collapse Reveal the importance of proof of reserves in avoiding situations involving misappropriation of users’ funds. While exchanges have started proactively sharing wallet addresses to prove users’ funds are there, many entrepreneurs, including Kraken CEO and Co-Founder Jesse Powelldescribed this practice as “pointless” as the exchanges failed to include the liabilities.

According to Powell, a full proof-of-reserve audit should include the sum of the client’s liabilities, user-verifiable cryptographic proof that each account was included in the sum and signatures proving the custodian’s control of the portfolios. While Kraken’s Proof of Reserve allows assets to be checked against the company’s liabilities, Powell continues to call out other players who missed including accounts with negative balances.

Powell has called out CoinMarketCap in the past for sharing incomplete proof of reserves because it lacks “cryptographic proof of client balances and portfolio control.” He reiterated that reserves are not a list of portfolios but rather assets minus liabilities.

Binance’s recently released Proof of Reserves system allows users to verify their assets using the Merkle tree. However, Powell shared his displeasure that the system failed to include accounts with negative balances, stating the following:

“The whole point of this is to understand if an exchange has more cryptocurrencies in custody than it owes to clients. Putting a hash on a worthless row identifier is nothing else.”

He also called on the media and journalists to refrain from “exaggerating it and misleading consumers.” Instead, he recommended taking the time to understand the motivation behind Proving Reserves.
