The audit events behind this ledger are sealed into CapchaChain blocks daily; each block is timestamped by an independent RFC 3161 authority and anchored into Bitcoin via OpenTimestamps (proofs confirm in a Bitcoin block hours after sealing — pending proofs are shown as pending, never as confirmed).

Verify offline: recompute SHA-256 of the receipt body (all fields except receipt_sha256, fixed key order) — it must equal the receipt hash above. Re-link the event log from the genesis zeros to the chain tip. If a Bitcoin anchor is confirmed, download the .ots proof and verify it with any standard OpenTimestamps client — no CapchaCloud verifier required.

CapchaCloud is software and never touches funds. This ledger continuously compares an instrument's issued liabilities (derived from a tamper-evident, hash-chained event log) against the most recent reserve figure ATTESTED BY THE TENANT. It is evidence of coverage as reported, NOT an audit of the reserves themselves, which remain the institution's and its regulators'/auditors' responsibility. Tamper-evident, not tamper-proof. No regulatory status is conferred.
