Proof-of-Possession for Asset Tokens

If you construct an actor token holding the public key of your asset and sign it with your asset’s private key, Salesforce binds that public key into your asset token. This pattern allows for what’s known as Proof-of-Possession or Holder of Key. The asset can prove that it holds the private key corresponding to the public key that Salesforce binds into the cnf claim during issuance. Proof-of-Possession helps provide greater assurance that the token is being presented by the actual asset it was issued to.
