Abstract:
The present invention relates to a system for issuing a document on the basis of a blockchain technology and, more particularly, to a system, for issuing an electronic document, comprising: a main blockchain comprising a plurality of main nodes; a sub-blockchain comprising a plurality of sub-nodes; a certificate request server for requesting an issuance of a certificate; and a certificate issuance server for generating the certificate in response to the issuance request from the certificate request server. The certificate issuance server transmits a first transaction relating to the generation of the certificate to a first main node.
