- A snapshot shows assets, not proof of solvency.
- A Merkle tree checks only your balance.
- Loans, debts, and omitted liabilities can be missing.
Exchanges publish these reports so customers can check that their coins are there, but they answer only a narrow question about assets at one moment.
What proof of reserves shows
A proof of reserves is a snapshot of assets at one moment. A Merkle tree proof lets you check that your balance is included.
Why snapshots miss liabilities
A proof of reserves usually counts only customer crypto assets. It does not include the exchange's loans, debts, or other obligations.
How it differs from a full audit
An auditor's attestation is a limited review. It checks exchange numbers against wallet addresses at one time, using data the exchange provides. A full audit is broader.
What it cannot guarantee
A proof of reserves does not guarantee that withdrawals will stay open. It does not prove that customer assets are segregated, and US bankruptcy law does not give customers automatic priority.
