Proof-of-Reserves

Definition ∞ Proof-of-Reserves is an auditing method used by cryptocurrency custodians to publicly demonstrate that they hold the assets they claim to possess. This process typically involves a cryptographic verification, often using Merkle trees, to confirm that a custodian’s reported liabilities are fully backed by corresponding assets held in their control. It allows users to independently verify their balances are included in the audit without revealing individual account details. The objective is to enhance transparency and trust in centralized entities by providing verifiable evidence of solvency.
Context ∞ Proof-of-Reserves has become a critical topic in crypto news, especially after incidents involving the collapse of centralized exchanges that lacked transparent asset backing. Regulators and industry participants are increasingly advocating for mandatory and regular PoR audits to protect user funds and prevent fraud within the crypto ecosystem. Reports often scrutinize the methodologies and comprehensiveness of these audits, debating their effectiveness in truly assuring solvency. The ongoing push for greater transparency in custodial services continues to drive discussions around this mechanism.
