Proof of Reserves enables transparent verification that platforms hold enough on‑chain assets to cover user withdrawals. By combining wallet proofs with Merkle‑tree aggregated liabilities, and backed by auditor oversight, PoR restores trust post‑FTX. However, users must evaluate audit frequency, scope, and coverage of off‑chain obligations. Real‑time systems like Chainlink and live Skynet dashboards from CertiK elevate trust and operational integrity. As crypto matures, PoR will be a cornerstone of credible, compliant custody and asset issuance.
