FIG. 1 is a flowchart of a federated chain combination consensus method in an embodiment of the present invention. The embodiment of the invention provides a alliance chain combination consensus method, which comprises the following specific implementation processes:
(1) Nodes in the alliance chain can be divided into core nodes, common nodes and query nodes; if a participant applies to join the alliance chain, one node mode can be selected according to the actual situation and the requirement of the participant, so that the participation threshold of the participant of the alliance chain is effectively reduced.
The alliance chain is initiated by some important organizations or important core enterprises in some industries, the alliance chain is built by the important organizations or the important core enterprises and shares data with each other, an initiator node of the alliance chain serves as a core node of the alliance chain, and a chain formed by the core nodes serves as a core chain in the alliance chain. Because the authority of the core node is higher and plays a key role in the alliance chain, firstly, the party applying for the core node needs to be authenticated by other core nodes, and the party applying for the core node needs to have stronger node operation and maintenance capability, can provide high-performance node service, and is suitable for a financial institution or a core enterprise to join the alliance chain in a core node mode.
The application of the common node only needs to authenticate the core node which is in butt joint with the common node, and the core node which is in butt joint with the common node and other common nodes under the core node form a common chain in the alliance chain. The common node only needs to participate in the common knowledge in the common chain, does not need to participate in the common knowledge in the whole alliance chain, has lower requirements on hardware and network of the common node, and is suitable for being added into the alliance chain by upstream and downstream medium-sized enterprises such as core enterprises or medium-sized and small enterprises in the mode of the common node.
The inquiring node only synchronizes the core node data in the alliance chain or forwards the uplink request data to the core node, and does not participate in any data consensus. Therefore, the requirements on the hardware and the network of the query node are minimum, and the method is suitable for some small enterprises in the industry chain to join the alliance chain through the query node.
Fig. 2 is a schematic diagram of a federation chain node network composed of core nodes, common nodes and query nodes according to an embodiment of the present invention.
(2) The core chain adopts RBFT consensus algorithm to ensure the strong consistency of the data among the core nodes, and all the node data of the alliance chain are based on the account book data of the core nodes. The common chain adopts a RAFT consensus algorithm, and common nodes do not participate in the consensus of the core chain.
(3) When the core node receives the data, the core chain adopts RBFT consensus algorithm to make consensus on the data. The core node also transmits the data to the common node connected with the core node, and the common chain carries out consensus on the data by adopting a RAFT consensus algorithm. The common identification of the core chain and the common chain can be synchronously carried out without mutual interference, thereby avoiding the influence of node hardware configuration or network difference among nodes on the whole node network common identification and effectively improving the alliance link point common identification efficiency. When the core chain data consensus is completed, the consensus data is synchronized to the querying node.
When the common node receives data, the common chain carries out consensus on the data by adopting a RAFT consensus algorithm, and distributes the data to other core nodes for carrying out data consensus through the core nodes connected with the common chain.
