Method providing transaction integrity and confidentiality in heterogeneous blockchain platforms

摘要

The method for providing transaction integrity and confidentiality in a heterogeneous blockchain platform according to the present invention is a method of providing transaction integrity and confidentiality by different consensus algorithms when a transaction occurs while configuring different blockchain networks with a plurality of nodes. a plurality of blockchain networks each generating blockchain blocks; and a single circle block chain network that selects one representative node from among a plurality of nodes constituting each of the plurality of block chain networks to operate as an intermediary node that can link the plurality of block chain networks with each other, , it is characterized in that, in the case of a block containing sensitive information that should only be disclosed in a specific blockchain network, a zero-knowledge proof method is provided so that the specific transaction contents of the specific blockchain network can be confidential and verified.
