In a blockchain network, some nodes may exist in both networks simultaneously, and there is a function of associating both networks and broadcasting transactions occurring in both networks, and nodes existing in both networks are referred to as a set of composite node groups.
The nodes in the same composite node group have the same chain structure. Their block contains the transaction information for both networks. And for the block chains of other common nodes, the blocks only contain the transaction information of the network where the common nodes are located.
As shown in fig. 1, there are two blockchain networks network a and network B. Wherein the nodes Node1, Node2, Node3 and Node4 are a composite Node group. They belong to both network a and network B and their chain structures are the same, containing the transaction information that takes place in both network a and network B.
Once a transaction occurs, the compound node assumes the task of broadcasting the transaction across the network. When there is a transaction, if all compound nodes in the same group of compound nodes broadcast the same transaction, the amount of broadcast will be greatly increased. Therefore, the scheme provides a trust broadcast method based on the block chain, and in the same group of composite nodes, a completely trusted node is taken as a trust node and has a broadcast function. And other compound nodes in the same group are used as check nodes to verify whether the content broadcast by the trust nodes is correct or not, and the verification process is completed within the first time.
It should be noted that the technical features such as the block chain and the transaction information related to the patent application of the present invention should be regarded as the prior art, and the specific structure, the operation principle, the control mode and the spatial arrangement mode of the technical features may be selected conventionally in the field, and should not be regarded as the invention point of the patent application, and the patent application is not further specifically described in detail.
It will be apparent to those skilled in the art that modifications and equivalents may be made in the embodiments and/or portions thereof without departing from the spirit and scope of the present invention.
