Penetration-type right confirmation and supervision method and system based on master-slave multiple chains

The invention provides a transmission type right confirmation and supervision method and system based on master-slave multiple chains. The method comprises the steps of 1, generating three block chains which are respectively recorded as a supervision chain, a right confirmation evidence storage chain and a flow evidence storage chain; wherein the supervision chain is used as a main chain, the right confirmation evidence storage chain is used as a slave chain of the supervision chain, and the flow evidence storage chain is used as a slave chain of the right confirmation evidence storage chain; step 2, storing user information on a corresponding block of the supervision chain, wherein the user information comprises a digital identity DID of a user and specific identity information bound with the digital identity DID; 3, storing a right confirmation evidence storage record on a corresponding block on the right confirmation evidence storage chain, wherein the right confirmation evidence storage record comprises a
