Note: The following feature is only available with Jade Plus.
Each individual Jade Plus manufactured by Blockstream contains a unique private key specific to that device, with its corresponding public key signed by Blockstream. The resulting signature is stored on Jade Plus, and Blockstream will only sign the public key of devices that the company manufactures. This process allows end users to complete a challenge with their Jade Plus once it is received to verify whether or not their unit is genuine or if it was created by a 3rd party.
Genuine Check
1.
During Jade Plus setup with Blockstream Green, a prompt will be shown to initiate the genuine check process. Tap Genuine Check to proceed.
Tip: If you are using a different application or your Jade Plus is already initialized, you can perform a genuine check using the web app.
2.
Select Yes on Jade Plus to sign the genuine check challenge.
3.
If the Jade Plus you received completes the challenge successfully, you may tap Continue with Jade to finish the setup process. If you receive a note that your device is not genuine, please contact support immediately and do not use your Jade Plus.
Note: If you are using DIY hardware, you should not expect your device to pass the Genuine Check and you may select Continue as DIY to use your generic hardware with Green.
