To further illustrate the technical solution of the present invention, the following is described with specific examples:
as shown in table 1, a routing table is provided for this example. In the routing table of this example, type a represents a data collection node, type B represents an accounting node, and type C represents a policing node.
Table 1 routing table
First, a routing table is initialized. Each node accessing the blockchain reads an initialized routing table from the database when the node program is started. The initialized routing table has two sources, if the node is a restarting node, the initialized routing table is the last routing table maintained by the node before restarting, and if the node is added into the block chain network for the first time, the routing table is a long-term active or stable node IP carried by the node program.
Then, according to the system rule, reading the initialized routing table, and sending message information through a port in the initialized routing table, wherein the message information comprises the IP address of the node, the network service information, the type information, the time information, the detected adjacent node information and necessary verification information. Then, monitoring a preset interface, receiving the message information, analyzing the network service of the adjacent node and calculating the network delay. And judging whether the network service and the network delay meet the requirement of the routing table of the current node, and if not, continuing to send and receive the message. If the routing table meets the requirement, the message information is analyzed, the information of the type, IP, port and the like of the adjacent node is obtained, and then the initialized routing table is updated.
In the process of chaining the collected power grid data, firstly, the power grid data collection node collects the power grid related data and signs the data.
And then, a data transmission module of the data acquisition node reads a preset rule and a routing table, and for the data acquisition node, the data transmission module is positioned at the most marginal end of the whole block chain network, so that the data acquisition node does not need to have the capacity to participate in accounting rights competition and does not store blocks. So the routing rule for data collection node is a- > B, i.e. data of data collection node a is only broadcast to accounting node B.
And broadcasting the signed data and the certificate address by a data transmission module of the data acquisition node according to the IP address of the type B in the distributed routing table.
And the data transmission module of the accounting node receives the data sent by the data transmission module of the data acquisition node, and stores the data in the data cache.
And starting an account book verification module according to the signature data received by the data transmission module of the accounting node, analyzing and obtaining the public key of the node according to the certificate address, verifying the signature through the public key, passing the verification, and writing the signature into a block chain to be generated.
The accounting node starts an accounting right contention module to contend for accounting right.
And the data transmission module of the node acquiring the accounting right reads a preset rule and reads a classified dynamic routing table, wherein the type A in the dynamic routing table represents a data acquisition node, the type B represents an accounting node, and the type C represents a supervision node. For a new block, the predetermined rule is B- > BC needs to broadcast all nodes except type A.
And the data transmission module of the node acquiring the accounting right proves the IP addresses corresponding to the broadcast type B, the broadcast type C and the node by the new block and the accounting right.
In summary, the present invention employs a classified routing technology to directly access all nodes to the blockchain network, so that the capacity of the blockchain network is greatly increased, the data security is ensured, and meanwhile, the performance degradation caused by the increase of nodes is avoided. By adopting the routing table with the attribute information, the number of unnecessary nodes participating in consensus can be reduced on the premise of ensuring normal data transmission, unnecessary data transmission among the nodes is reduced, network load is reduced, and transmission efficiency is improved. Through testing, compared with a direct uplink mode, the time required for achieving consensus by adopting the method of the patent is reduced by 95% under the virtual machine testing environment of the Ethernet with 100 nodes. In the aspect of safety, compared with the existing central data uploading process, the data uploading and modification need to be agreed by all accounting nodes in the block chain, so that the possibility of data tampering is greatly reduced, and the safety of the system is greatly improved.
As shown in fig. 4, which is a schematic structural diagram of an embodiment 1 of a system for distributing blockchain data based on type attribute information disclosed in the present invention, the system may include:
a routing table initialization module 401, configured to generate a dynamic routing table based on type attribute information of each node on the block chain;

And a data transmission module 402, configured to transmit data by each node in the block chain based on the dynamic routing table corresponding to the node.
Then, when data is distributed, each node on the block chain distributes the data to the nodes with the attributes meeting the rule requirements according to the corresponding dynamic routing table.
In summary, in the above embodiment, when data needs to be distributed, first, each node in the block chain generates a dynamic routing table based on the type attribute information of the node, and then each node in the block chain transmits the data based on the dynamic routing table corresponding to the node. By adopting the routing table with the node type attribute information, the number of unnecessary nodes participating in consensus can be reduced on the premise of ensuring normal data transmission, unnecessary data transmission among the nodes is reduced, network load is reduced, and data transmission efficiency is improved.
