The invention relates to a
blockchain-based
domain name resolution
system, characterized in that the
domain name resolution
system adopts a
layered structure comprising a top-level
domain name chain network, a second-level domain name
chain network, a future network node and an existing DNS
system network; the top-level domain name
chain network links the second-level domain name chain network, the future network node and the existing DNS system network respectively, and the top-level domain name chain network is used for each professional organization to deploy the
server nodes having a reliable performance respectively to form a union
blockchain network, wherein each node
server records the information of all the current top-level domain names, the second-level domain name chain nodes, the future network nodes and the root nodes of the existing DNS system; the second-level domain name chain network is used for the registration and management of domain names, and recording of all the second-level domain names and their subdomain names; the future network node is used for the storage of the
metadata and index in the future network. The invention reduces the resolution request, thus effectively improving the efficiency of domain
name resolution.
