While Kraken’s proof-of-reserve does allow verification of assets against the company’s liabilities, Powell continues to call out other players that have missed out on including accounts with negative balances.

Powell called out CoinMarketCap in the past for sharing an incomplete proof-of-reserves as it lacked “cryptographic proof of client balances and wallet control.” He reiterated that reserves are not the list of wallets but assets minus liabilities.
Binance’s recently released proof-of-reserves system allows users to verify their assets using a Merkle tree. However, Powell shared his displeasure as the system failed to include accounts with negative balances, stating that:
Moreover, he asked the media and journalists to refrain from “overselling it and misleading consumers.” Instead,
