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

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 front of the note, around the edges of the border, a Bitcoin Cash icon is tessellated as chain mail. On the back of the note, the background orange color are the words Bitcoin Cash repeated many times. To see these features more clearly, please use a magnifying glass.
