Understanding Proof of Reserves Technology

What is Proof of Reserves (PoR)?

PoR is a cryptographic attestation that verifies a crypto exchange holds sufficient assets to cover all customer deposits. It provides transparency without compromising individual account privacy.

How OKX's PoR Works:

  1. zk-STARK Verification: Uses zero-knowledge proofs to validate reserves without exposing sensitive data
  2. Wallet Ownership Confirmation: Publicly verifiable signatures prove OKX controls reserve wallets
  3. Merkle Tree Accounting: Tamper-proof system verifies inclusion of all user balances
  4. Reserve Ratio Calculation: Compares total user assets to exchange reserves

The zk-STARK Advantage:
