    摘要： A method for automatically provisioning data for an opaque blockchain based on prior consent includes: receiving a consent request including transaction criteria and at least two digital signatures, the first digital signature generated by a regulating entity and the second digital signature generated by a moderating entity in a blockchain network; validating the first and second digital signature; digitally signing the received consent request using a private key of a first cryptographic key pair; transmitting the digitally signed consent request to the regulating entity; receiving a query request from the regulating entity, the query request including an executable query; executing the executable query to identify transaction data for electronic transactions in compliance with the transaction criteria; and transmitting the identified transaction data to the regulating entity.
