In one embodiment, as shown in Fig. 2, the broadcast message based on block chain technology that Fig. 2 is one embodiment passes
Transmission method flow chart proposes a kind of broadcast message transmission method based on block chain technology in the present embodiment, specifically can wrap
Include following steps:
S110: shared block chain is constructed using each system mutually communicated as node, the node receives each system
The broadcast message of sending.
In practical applications, the system for needing mutually to communicate is more and more, in order to preferably guarantee to disappear between each system
The efficiency and accuracy rate of transmitting are ceased, thus in this step, several systems mutually communicated are constructed jointly as node
One shared block chain, each node can receive the broadcast message of the sending of the system in the node.
For example, in the case where previous, server is obtained firstly the need of by message sender when needing to push a piece of news
The PUSH message is taken, the PUSH message is pushed into message receiver then through third-party platform or other middlewares, this
The processing mode for needing the centralization of the centralized processings such as server and middleware is planted, can not ensure the authenticity of message, when need
When facing the communication system of certain amount grade, message quickly and accurately can not be transmitted to message by this kind of processing mode
Recipient.
And in the present solution, using the system mutually communicated as the node in shared block chain, for example, above-mentioned push away news
It send in mode, can regard message sender and at least one message receiver communicated with the message sender as shared region
Node in block chain, node corresponding with the message sender is as source node, node conduct corresponding with the message receiver
The message that the system that destination node, source node and destination node all can receive the node issues, thus opposite certain amount grade
When intersystem communications, the transmission of message is carried out by the shared block chain of this programme, can fast and accurately be broadcast out message
It goes.

In with no restrictions.
In addition, the broadcast message in this programme refers to the message for needing to carry out wide-scale distribution, not in general sense
Message through broadcast communication.
S120: when the arbitrary node on the shared block chain generates broadcast message, using the node as source node, to institute
State broadcast message addition source node mark and be packaged into broadcast message wrap transmitted to adjacent node.
In this step, each system can send message, correspond in shared block chain, i.e., arbitrary node can produce extensively
Broadcast message；Such as, relationship trading or information transmission are carried out in the client application that user can install on its computer or mobile phone,
The corresponding client application of the user is a certain node for generating message in shared block chain, which is considered as source section
Point, which carries out relationship trading in the application program of its client or another party of information transmission is then used as in addition to source node
Other nodes in shared block chain, other nodes can quickly receive user's hair by sharing the transmission mode in block chain
The Transaction Information etc. sent.
Certainly, it before the message of the source node is independently sent to other nodes, needs to add the message to be sent
It is packaged after adding source node to mark, forms broadcast message packet, be then transmitted to the broadcast message packet adjacent with the source node
Node in.
Above-mentioned to mark to sent message addition source node, which marks the time that can be the transmission message
Stamp, encryption information etc. can search source node by source node label, and verify the authenticity of message in the source node
Deng.
S130: after adjacent node receives the broadcast message packet, to the node of the broadcast message packet addition itself
Label, and transmitted after being repacked to broadcast message packet to adjacent node；Until being transferred to described shared
All nodes of block chain.
In this step, then broadcast message addition source node is marked and is packaged into broadcast in above-mentioned steps S120
Message package is transmitted to adjacent node, can be by the broadcast message of packing when adjacent node receives the broadcast message packet
Packet is first decompressed, and is repacked after the vertex ticks of itself is then added to the broadcast message after the decompression, adjacent node
Other in addition to broadcast message packet after repacking again sends the respective node come except transmission broadcast message packet to are adjacent
Node, until all nodes of the broadcast message transmission into shared block chain.
Above-mentioned all nodes by broadcast message transmission into shared block chain, refer to the broadcast for sending the source node
Message is transmitted to the other systems of the intercommunication of system corresponding with the source node, the corresponding node of other systems here
Also referred to as destination node.
In addition, vertex ticks here and above-mentioned source node label belong to same type of label, which can be with
It is timestamp, the encryption information etc. for receiving the broadcast message, source node can be traced back to by the vertex ticks, and verifying is extensively
Broadcast whether message is tampered in transmission process.
In the present solution, adding the vertex ticks of itself after the broadcast message packet that source node is sent is decompressed, then addition is saved
Broadcast message after point label re-starts packing, to transmit it to next node adjacent thereto, under so continuing
It goes, until all nodes that the packet that will broadcast the message is transmitted in shared block chain.Such broadcast mode based on the algorithm that floods, no
It is required that maintenance and relevant router-level topology, require nothing more than and receive the node of information and forward data packet in the form broadcasted, allows data
Packet obtains fast-forwarding.
The above-mentioned broadcast message transmission method based on block chain technology is constructed each system mutually communicated as node
Shared block chain, the node receive the broadcast message that each system issues；When the arbitrary node on the shared block chain produces
When raw broadcast message, using the node as source node, broadcast message addition source node is marked and is packaged into broadcast message packet
It is transmitted to adjacent node；After adjacent node receives the broadcast message packet, certainly to the addition of broadcast message packet
The vertex ticks of body, and transmitted after being repacked to broadcast message packet to adjacent node；Until being transferred to
All nodes of the shared block chain.
By each system for needing mutually to communicate all as the node in shared block chain, each system issues this programme
Message data be packaged into chain, share the resource in block chain；It, will be in shared block chain when needing extensive broadcast message
The arbitrary node of broadcast message is generated as source node, and by the source node by broadcast message transmission to adjacent node, directly
All nodes extremely by the broadcast message transmission into shared block chain, this broadcast mechanism based on the algorithm that floods, can be fast
The message that system issues is spread to all nodes in shared block chain by speed, realizes the communication between big order of magnitude system；Separately
Outside, among the nodes transmit during, the vertex ticks in source node and each adjacent node can be packaged together into
Chain, and then can trace to the source the broadcast message, to verify the authenticity of broadcast message, the message for effectively avoiding system from issuing
A possibility that being tampered.
In one embodiment, the step of each system mutually communicated being constructed shared block chain as node, can be with
Include:
(1) several systems mutually communicated are obtained, and calculate the network distance between each system, obtain most short network
Distance；
(2) shared block chain is constructed for each system as node according to the most short network distance.
In the present embodiment, in order to which the message for allowing system to issue quickly is spread among the system being in communication with each other therewith, share
Network distance in block chain between each node is the smaller the better；Information is carried out by the smallest network distance between system two-by-two
Transmission can guarantee the rate of message transmission.
Thus, when the system for being in communication with each other several constructs shared block chain as node, each system is calculated first
Network distance between system to obtain most short network distance between each system, and is realized altogether according to this most short network distance
The allocation optimum of each node in block chain is enjoyed, provides efficient solution for the transmitting of follow-up system message.
In one embodiment, when the arbitrary node on the shared block chain generates broadcast message, it is with the node
Source node marks and is packaged into the step that broadcast message packet is transmitted to adjacent node to the broadcast message addition source node
After rapid, can also include:
(1) data volume of the broadcast message of the source node publication is obtained, and judges whether the data volume is greater than data
Measure preset value；
(2) when the data volume is greater than the data volume preset value, the broadcast message is divided into and is mutually related
Multiple sub- message, and be packaged into broadcast message packet after successively marking to each sub- message addition source node and carried out to adjacent node
Transmission.
In the present embodiment, in the broadcast message autonomous type for generating source node to adjacent node-node transmission during,
The data volume of the broadcast message issued to system corresponding in the source node is needed to be monitored, to judge the number of system sending
Whether it is more than preset value according to amount, avoids the message when the publication of a certain system excessive, causes to disappear during message is transmitted
The phenomenon that ceasing entanglement.
For example, the data volume setting data volume preset value issued to system in above-mentioned source node is 10Mb/s, when the source is saved
When the data volume that point issues is more than 10Mb/s, that is, the data volume for assert that the source node is sent is excessive, is needed at this time by excessive number
It is divided into multiple sub- message that are mutually related according to amount, and is packaged after successively adding source node label to each sub- message, this
Sample can successively transmit the broadcast message packet that is mutually related, the number for avoiding disposable transmitted data amount excessive into shared block chain
According to packet；Also, it, can be according to multiple broadcast when message reciever receives the broadcast message packet formed after multiple sub- message are packaged
Relevance between message package determines whether the broadcast message packet is tampered or omits.
It should be noted that the above-mentioned message issued to correspondence system in source node carries out the setting of data volume preset value,
The setting of data volume preset value can also be carried out to the message that system corresponding in other nodes in shared block chain is issued, and each
The size of data of data volume preset value may be the same or different in node, and the concrete condition depending on the system is set, In
This is with no restrictions.
In one embodiment, when the arbitrary node on the shared block chain generates broadcast message, it is with the node
Source node marks and is packaged into the step that broadcast message packet is transmitted to adjacent node to the broadcast message addition source node
After rapid, can also include:
(1) message frequency of the broadcast message of the source node publication is obtained, and judges whether the message frequency is greater than
Predetermined frequency value；
(2) when the message frequency is greater than the predetermined frequency value, the source node is labeled as suspect node, and refuse
The broadcast message beyond predetermined frequency value range of the source node publication described absolutely.
In the present embodiment, in the broadcast message autonomous type for generating source node to adjacent node-node transmission during,
It also needs the message frequency for the broadcast message issued to source node to be monitored, and judges whether the message frequency of monitoring is greater than frequency
Rate preset value causes altogether in order to avoid sending excessively frequent message when a certain system is by malicious attack or virus infraction
Enjoy in block chain the corresponding system of other nodes also by malicious attack the phenomenon that generation.
For example, it is 20 upper limits per hour that the source node, which is arranged, to issue the predetermined frequency value of broadcast message, when monitoring this
When the frequency that source node sends broadcast message is more than the preset value, which is labeled as suspect node, this is suspicious receiving
When the broadcast message that node issues, selection rejection exceeds the broadcast message of the predetermined frequency value range.
In addition, when continuing for some time interior monitoring suspect node, and find the message frequency for the broadcast message that it sends
When beyond predetermined frequency value, the suspect node of the node can be marked and be converted to abnormal nodes label, and refuse to transmit all be somebody's turn to do
The broadcast message that abnormal nodes are sent, so that convenient checked and corrected to each node in shared block chain.
It in one embodiment, include destination node in the shared block chain, the destination node receives described shared
The broadcast message packet that other nodes are sent in block chain；Until be transferred to the shared block chain all nodes the step of it
Afterwards, can also include:
(1) whether the storage state for detecting destination node in the shared block chain updates, when the storage state updates
When, the storage information of update is obtained, and received broadcast message packet is searched in the storage information；
(2) it is traced to the source according to the source node label in the broadcast message packet broadcast message packet, to determine more
Whether new storage information is broadcast message packet that the source node is sent.
In the present embodiment, the broadcast message packet that source node is issued is transmitted to all nodes by shared block chain,
In include destination node, which can receive the broadcast message packet that source node passes through shared block chain transmission.It needs
Bright, which refers to that corresponding system is the node of message sender, which refers to corresponding system
For the node of message receiver, the number of source node number and destination node here at least one, herein with no restrictions.
After the broadcast message packet that source node is sent is transmitted to all nodes in shared block chain, need to destination node

One shared block chain, each node can receive the broadcast message of the sending of the system in the node.
For example, in the case where previous, server is obtained firstly the need of by message sender when needing to push a piece of news
The PUSH message is taken, the PUSH message is pushed into message receiver then through third-party platform or other middlewares, this
The processing mode for needing the centralization of the centralized processings such as server and middleware is planted, can not ensure the authenticity of message, when need
When facing the communication system of certain amount grade, message quickly and accurately can not be transmitted to message by this kind of processing mode
Recipient.
And in the present solution, using the system mutually communicated as the node in shared block chain, for example, above-mentioned push away news
It send in mode, can regard message sender and at least one message receiver communicated with the message sender as shared region
Node in block chain, node corresponding with the message sender is as source node, node conduct corresponding with the message receiver
The message that the system that destination node, source node and destination node all can receive the node issues, thus opposite certain amount grade
When intersystem communications, the transmission of message is carried out by the shared block chain of this programme, can fast and accurately be broadcast out message
It goes.
The quantity of above-mentioned source node and destination node can be increased or be deleted according to actual needs, not limited herein
System, above-mentioned PUSH message are only an example of this programme, and this programme applies also for other message for needing to broadcast, at this
In with no restrictions.
In addition, the broadcast message in this programme refers to the message for needing to carry out wide-scale distribution, not in general sense
Message through broadcast communication.
First transmission module 220, for when on the shared block chain arbitrary node generate broadcast message when, with the section
Point is source node, mark to broadcast message addition source node and is packaged into broadcast the message to wrap and passes to adjacent node
It is defeated.
In this module, each system can send message, correspond in shared block chain, i.e., arbitrary node can produce extensively
Broadcast message；Such as, relationship trading or information transmission are carried out in the client application that user can install on its computer or mobile phone,
The corresponding client application of the user is a certain node for generating message in shared block chain, which is considered as source section
Point, which carries out relationship trading in the application program of its client or another party of information transmission is then used as in addition to source node
Other nodes in shared block chain, other nodes can quickly receive user's hair by sharing the transmission mode in block chain
The Transaction Information etc. sent.
Certainly, it before the message of the source node is independently sent to other nodes, needs to add the message to be sent
It is packaged after adding source node to mark, forms broadcast message packet, be then transmitted to the broadcast message packet adjacent with the source node
Node in.
Above-mentioned to mark to sent message addition source node, which marks the time that can be the transmission message
Stamp, encryption information etc. can search source node by source node label, and verify the authenticity of message in the source node
Deng.
Second transmission module 230 wraps the broadcast message after receiving the broadcast message packet for adjacent node
The vertex ticks of itself is added, and is transmitted after being repacked to broadcast message packet to adjacent node；Until
It is transferred to all nodes of the shared block chain.
In this module, then broadcast message addition source node is marked and is beaten in above-mentioned first transmission module 220
Broadcast message packet is bundled into be transmitted to adjacent node, it, can be by packing when adjacent node receives the broadcast message packet
Broadcast message packet is first decompressed, and is repacked after the vertex ticks of itself is then added to the broadcast message after the decompression, phase
Adjacent node will repack again after broadcast message packet send to it is respective in addition to sending the node that broadcast message packet comes
Other adjacent nodes, until all nodes of the broadcast message transmission into shared block chain.
Above-mentioned all nodes by broadcast message transmission into shared block chain, refer to the broadcast for sending the source node
Message is transmitted to the other systems of the intercommunication of system corresponding with the source node, the corresponding node of other systems here
Also referred to as destination node.
In addition, vertex ticks here and above-mentioned source node label belong to same type of label, which can be with
It is timestamp, the encryption information etc. for receiving the broadcast message, source node can be traced back to by the vertex ticks, and verifying is extensively
Broadcast whether message is tampered in transmission process.
In the present solution, adding the vertex ticks of itself after the broadcast message packet that source node is sent is decompressed, then addition is saved
Broadcast message after point label re-starts packing, to transmit it to next node adjacent thereto, under so continuing
It goes, until all nodes that the packet that will broadcast the message is transmitted in shared block chain.Such broadcast mode based on the algorithm that floods, no
It is required that maintenance and relevant router-level topology, require nothing more than and receive the node of information and forward data packet in the form broadcasted, allows data
Packet obtains fast-forwarding.
The above-mentioned broadcast message transmission device based on block chain technology is constructed each system mutually communicated as node
Shared block chain, the node receive the broadcast message that each system issues；When the arbitrary node on the shared block chain produces
When raw broadcast message, using the node as source node, broadcast message addition source node is marked and is packaged into broadcast message packet
It is transmitted to adjacent node；After adjacent node receives the broadcast message packet, certainly to the addition of broadcast message packet
The vertex ticks of body, and transmitted after being repacked to broadcast message packet to adjacent node；Until being transferred to
All nodes of the shared block chain.
By each system for needing mutually to communicate all as the node in shared block chain, each system issues this programme
Message data be packaged into chain, share the resource in block chain；It, will be in shared block chain when needing extensive broadcast message
The arbitrary node of broadcast message is generated as source node, and by the source node by broadcast message transmission to adjacent node, directly
All nodes extremely by the broadcast message transmission into shared block chain, this broadcast mechanism based on the algorithm that floods, can be fast
The message that system issues is spread to all nodes in shared block chain by speed, realizes the communication between big order of magnitude system；Separately
Outside, among the nodes transmit during, the vertex ticks in source node and each adjacent node can be packaged together into
Chain, and then can trace to the source the broadcast message, to verify the authenticity of broadcast message, the message for effectively avoiding system from issuing
A possibility that being tampered.
