Proof of Reserves Meaning

Proof of Reserves (PoR) is an Auditing Procedure used by Crypto Exchanges and Custodians to Prove to their customers and regulators that they Actually Hold the assets they Claim to have in their Vaults. In the Wake of the FTX Collapse, PoR became the Industry Standard for Transparency. It is a Way for a Centralized Company to Prove its Solvency using Blockchain Proofs rather than just a Bank Statement.The technical Gold Standard for PoR is the Merkle Tree.

The exchange Hashes all of its Customer Balances into a Single Root. Each Individual Customer can then Verify that their Account Balance was Included in that root without the exchange Revealing everyone else's private data. At the same time, the exchange Signs a Message with its Cold Wallet to Prove that it Controls enough Bitcoin or ETH to Cover the Total Root Balance.A Complete Proof of Reserves also requires Proof of Liabilities.

Knowing an exchange has 10,000 BTC is Useless if they Owe their customers 20,000 BTC. A Full Audit (PoR + PoL) proves that the Assets are Greater than or Equal to the Liabilities.

Some companies now provide Real-Time Proof of Reserves, where an Attestation is Published Daily on their website, providing Constant Peace of Mind for the users.However, PoR is Not a Perfect Solution. It doesn't Prove that the exchange hasn't Borrowed the money Just for the Audit (a Snapshot Scam).

It also doesn't Account for Off-chain Liabilities (like a Private Bank Loan). Therefore, while PoR is a Huge Step Forward for Transparency, it should be Combined with Regulatory Oversight and Insurance to provide Full Protection for the Retail Investor.
