Proof of Reserves (PoR)
One important factor in determining the efficacy of an exchange’s custody measures is the presence of a proof of reserves policy. In this article, we’ll dive into what proof of reserves is, how it works, and why it’s important for exchange users to consider. <h2 id="whatisproofofreserves">Proof of reserves is a method by which a cryptocurrency exchange can prove to its clients that it is holding enough crypto assets to cover its liabilities. In other words, it is a way for exchanges to demonstrate that they have sufficient funds to meet user withdrawal requests. Proof of reserves requires an exchange to prove that it holds a certain amount of cryptocurrency, usually in the form of a signed message that is cryptographically secured. This message confirms that the exchange holds the requisite amount of assets and can be verified by users if need be. <h2 id="howdoesproofofreserveswork">How Does Proof of Reserves Work? Proof of reserves works by having an exchange sign a message that confirms it holds a certain amount of cryptocurrency. This message is usually a cryptographic hash that contains the following information: <ul> <li>The exchange’s public address</li> <li>The amount of cryptocurrency held in the address</li> <li>The date the message was signed</li> </ul> The exchange can then share this message with its users, who can verify that the exchange has the requisite amount of crypto assets to cover its liabilities. <h2 id="whyisproofofreservesimportant">Why Is Proof of Reserves Important? Proof of reserves is important for users of cryptocurrency exchanges because it ensures that the exchange is honest and has the necessary funds to cover user withdrawals. Without proof of reserves, users don’t know if an exchange is actually holding the amount of cryptocurrency it claims to be holding. Additionally, proof of reserves helps the cryptocurrency industry by preventing scams and fraud. By verifying that an exchange holds the necessary amount of crypto assets, users can rest assured that their funds are safe.
