Proof of Reserves vs. Proof of Solvency

| Term | Definition |
|-----------------------|---------------------------------------------------------------------------|
| Proof of Reserves | Verifies custodian holds claimed assets. |
| Proof of Liabilities | Confirms total owed to customers. |
| Proof of Solvency | Ensures reserves ≥ liabilities (PoR + PoL). |

PoR alone is insufficient—true solvency requires matching reserves to liabilities. OKX combines both for comprehensive verification.
