Understanding Proof of Reserves

Proof of Reserves (PoR) is a cryptographic method that:

  1. Verifies custodians hold sufficient assets to cover liabilities
  2. Provides transparent aggregate balance reporting
  3. Maintains individual account privacy
  4. Uses blockchain-based verification

OKX supports PoR for 22 high-liquidity cryptocurrencies including major coins and stablecoins.

OKX's PoR Technology Stack

zk-STARK Verification System

Our proprietary implementation features:

  1. Transparent algorithm: Uses Zero-knowledge proof principles
  2. FRI protocol: Ensures data authenticity
  3. Privacy protection: Never reveals specific amounts or addresses

Three Core Verification Rules

  1. Total Balance Constraint: Sum of all account balances equals reported total
  2. Non-negative Constraint: All accounts maintain positive balances
  3. Inclusion Constraint: Every account participates in verification
