Abstract
A computer-implemented system and method provide a privacy preserving token generation protocol. The method comprises initiating an order request, where the order request includes order public information and order private information. The method further comprises generating an address in a blockchain network that includes encrypting the address using a private key, and generating a hash of data incorporating the order private information and a signature of the hash. The signature of the hash is generated using the private key. The method further comprises transmitting the order request with the address, hash, and signature to a transport associated with the order, and identifying that the transport fulfilled the order request. The method further comprises validating that the transport fulfilled the order, calculating a token value associated with the transport, where the token value is related to a carbon emission footprint of the transport, and assigning the token value to the address.
