How OKX Uses Merkle Trees to Prove Crypto Reserves

Summary

The document describes OKX’s February 2023 proof-of-reserves report and explains how users can check whether their balances are included in the exchange’s reported liabilities. It says the exchange uses a Merkle tree so an individual can verify their balance is part of the user liability total, then compares that total with the on-chain balances of public wallets. The report covers BTC, ETH, and USDT and says OKX published more than 23,000 wallet addresses for public inspection.

The report also gives user traffic figures and claims that third-party analysis found OKX’s reserves to be fully composed of major crypto assets rather than its own platform token. These are reported claims, not an independent assessment within the document. Proof of reserves can provide evidence about asset holdings and liability inclusion, but the text does not explain how it addresses other obligations, asset encumbrances, or the timing of balances. It is therefore a transparency mechanism with limits, not a complete measure of an exchange’s financial condition.

Key ideas

• Merkle proofs let users check that their balances are included in reported exchange liabilities.
• The report compares total liabilities with balances visible in the exchange’s public on-chain wallets.
• OKX reported BTC, ETH, and USDT holdings in its February 2023 disclosure.
• The document’s clean-reserve designation comes from third-party analysis and excludes an exchange’s own platform token.
• Proof of reserves alone does not establish an exchange’s complete financial condition.
