Bitcoin Cash Note details
1. The note id
This is the production number of the note. All Bitcoin Cash Notes are produced sequentially and are marked as such.
2. The version number
The version number provides the exact release of the note. All changes to the note are released with a new version number – please see our changelog for details of the version history. Each release has a note id range associated with it, which is the note ids that were printed as of the particular version.
3. The face value
The face value is only for display purposes.
4. The Bitcoin Cash address
The unique public address in Bitcoin Cash address format for the note and its corresponding private key.
5. The QR Code
The QR code displayed on the note is an alternative ‘matrix barcode’ representation of the unique Bitcoin Cash address printed on the note. Use the QR code to conveniently capture the Bitcoin Cash address for blockchain explorer validation.
6. The private key & tamper-evident seal
This is where the private key for the note is sealed and where much of the note innovation and security is located. The private key is non-deterministic meaning it is unique, random and independently generated for the note. The private key is a string of random characters embedded underneath a tamper evident seal. Within the seal, the private key is further concealed with light impenetrable material. Any copies of the key made during the manufacture of the note e.g. for printing purposes, have been destroyed.
Advice for accessing the private key is below on this page.
7. The tamper-evident seal code
The 4 digit code printed at the top left-hand corner of the tamper-evident seal provides enhanced security against covering a tampered seal with a new seal. The 4 digit code equals the last 4 digits of the Bitcoin Cash address.
On the back of all of our notes, the background color has the words Bitcoin Cash repeated many times. To see these features more clearly, please use a loupe or magnifying glass.
9. The disclaimer
As stated on all of our notes releases, and also found in our terms and conditions.
