How to verify this receipt yourself
- Re-fetch the on-chain transaction:
https://whatsonchain.com/tx/103cffdb71e3b096aa3f28357ffe8e6df59d4f85405559f3bf9c2731bdfc64f3 — confirm an
OP_RETURN output starting with the bytes MBNT.
- Decode the OP_RETURN payload: bytes 6–25 are the
document_hash (sha256 of the canonical receipt doc, truncated to
20 bytes). It must match
6090593bd859cd80fc7577f5d6f9a79f645feeb1.
- Re-canonicalize the included
canonical.json from the
.mbnt bundle (jq -cS . canonical.json),
sha256 it, take the first 40 hex chars — must equal
6090593bd859cd80fc7577f5d6f9a79f645feeb1.
- Sha256 your original file — must equal the File SHA-256 above. The bundle does not contain the file (you kept it private).
What we kept: this bundle (downloadable above) and one
access-log line for this request.
What we did NOT keep: your file — it never left your browser. The on-chain anchor is permanent.
