The embodiment of the invention provides a public
blockchain network
system. The public
blockchain network
system comprises a
service user application terminal used for uploading basic application service data to a common node
server; a common node
server which performs preliminary
verification on the data and sends the data to the
verification node
server for
consensus processing; a verificationnode server which performs
consensus processing on the data, and establishes block storage basic application service data after the
consensus processing is successful; an extended application unit which is used for customizing an extended application service, so that the
service user application terminal uses an application program corresponding to the extended application service; a cross-chain protocol
management unit which is used for setting a connection protocol between different blockchains; by setting the user application terminal and the node server on the network, the design of a useraccount and a node account is realized, so that the network is more modular,
system management and upgrading are facilitated, meanwhile, an application extension function is added, different enginesare supported, different
technology stack developers can be attracted to join, a cross-chain protocol is also set, and connection between different blockchains is realized.
