## Quick answer
A proof of reserves report is an asset-side snapshot at one block height. Without a verified liability figure, a coverage ratio says little about whether a custodian is solvent.

## Summary
A proof of reserves update shows assets at a moment, not what is owed. Read the scope, the timestamp and the denominator before trusting the coverage ratio.

## FAQ
Q: Does a reserve report prove a platform is solvent?
A: No. It proves assets exist at a moment. Solvency requires liabilities too, and most reports either omit them or state them without independent verification. A reserve report is one input to a solvency question, not an answer.
Q: What is a Merkle tree proof of balances?
A: It is a way to commit to a set of account balances without publishing them. The entity publishes a root hash, and each user can check that their balance is included without seeing anyone else's. It proves inclusion, not completeness: an omitted account leaves no trace.
Q: Why are liabilities harder to prove than assets?
A: Assets sit on a public ledger and can be summed by anyone. Liabilities live in private databases, involve personal data, and require cooperation from customers to verify. Proving the complete set, rather than a selected set, needs controls that a snapshot does not have.
Q: What is the difference between an attestation and an audit?
A: An attestation reports on specific procedures against specific assertions at a point in time. An audit expresses an opinion on financial statements as a whole and includes an assessment of controls. Attestations are narrower and are commonly used because they are faster and cheaper.
Q: Is a coverage ratio above 100 percent a safety signal?
A: Only if the liability figure is complete and the assets are unencumbered. A ratio computed against a partial liability set can exceed 100 percent while the entity is short of what it owes. Recompute it with the numbers in the report and read the scope notes first.
Q: How often should reserves be updated?
A: More often is generally better, but frequency without liability coverage mostly adds snapshots of the same incomplete picture. A monthly update with a clear scope is more informative than a daily total with no stated liabilities. Rules and disclosure expectations differ by jurisdiction, so check local requirements.
