Abstract

Disclosed herein are system, method, and computer program product embodiments for issuing assets and/or asset tokens using zero-knowledge proofs (“ZKPs”). An issuance system may receive a command to issue an asset. The issuance system may determine that issuing the assets would not violate administrator-defined or network-defined rules that may govern the types of assets and/or the quantity of assets that the issuance system may issue. The issuance system may then issue the assets and generate a ZKP corresponding to the issuance and indicating adherence to the rules while concealing information related to the asset token, such as the types of assets and/or quantity of assets. The issuance system may publish the ZKP to a blockchain so that verifier nodes may confirm that the issuance system adhered to the rules while still preventing access to the underlying issuance information.
