Sustainable tokens for supply chain with privacy preserving protocol

A system for implementing privacy preserving tokens, comprising:

• a manufacturing system;
• and
• a blockchain controller;
• wherein the system is configured to:
• use a blockchain controller processor of the blockchain controller to:
• receive order information related to an order requiring use of a transport, the order information comprising an address associated with a cryptographic key in a blockchain network;
• validate that the transport fulfilled the order;
• calculate a token value associated with the transport, wherein the token value is related to a carbon emission footprint of the transport for transporting the order;
• and
• assign the token value to the address;
• and
• use a manufacturing system processor of the manufacturing system to:
• initiate an order request, wherein the order request includes:
• a) order public information needed by the transport and a provider of the carbon emission footprint, and b) order private information;
• generate the address in a blockchain network that includes encrypting the address using a private key;
• generate a hash of data incorporating the order private information;
• generate a signature of the hash, wherein the signature of the hash is generated using the private key;
• transmit the order request with the address, hash, and signature to the transport;
• and
• identify that a transport fulfilled the order request.
