A backbone node access method and a blockchain system are disclosed. In the backbone node access method, after receiving an access request of a backbone node in a second blockchain system, a first node of a first blockchain system determines a voting node and requests the voting node to vote on the access request; the voting node feeds back a voting result; after determining to approve the access request according to the voting result, the first node determines a second node and sends anchoring message to the second node; and the second node is anchored with the backbone node based on the anchoring message, so that the backbone node accesses to the first blockchain system, the second blockchain system becomes a slave chain system of the first blockchain system, and the first blockchain system becomes a master chain system of the second blockchain system.
