The User holds the private keys to their own Green APP. Green does not have access to user APPs of the green Blockchain. When a User creates a green APP, the green Blockchain software generates a cryptographic private key and public key pair that the User must use to send and receive GREEN. The User is solely responsible for storing, outside of Green’s Services, a backup of any User’s green APP, private key(s), or transaction information that the User maintains in the green APP or otherwise with the Green Services. If the User does not backup the green APP, the User may not be able to access the GREEN in the event that Green discontinues some or all of the Green Services.
