Fig. 1 and Fig. 2 are please referred to, Fig. 1 is the application scenarios of the method for data synchronization of block chain provided in an embodiment of the present invention
Schematic diagram.Fig. 2 is the schematic flow chart of the method for data synchronization of block chain provided in an embodiment of the present invention.The data of block chain
Synchronous method is applied in server, synchronous for the data to each node in server.
Fig. 2 is the flow diagram of the method for data synchronization of block chain provided in an embodiment of the present invention.As shown in Fig. 2, should
Method includes the following steps S110 to S180.
S110, the synchronizing traffic data of cochain will be needed local to each node using common recognition algorithm.
In the present embodiment, the business datum of cochain is needed to refer to the data for needing to be synchronized in block chain.Pass through on chain
Common recognition algorithm will need the synchronizing traffic data of cochain to node local account book.
In one embodiment, as shown in figure 3, above-mentioned step S110 may include step S111~S113.
S111, acquisition need the business datum of cochain；
S112, to needing the business datum of cochain encrypt and cochain；
Business datum after S113, Network Synchronization cochain of being known together by block chain is local to each node.
According to Scenario Design, needs the business datum of cochain to be digitally signed correlation in user, then and added
The close interface that recalls carries out cochain.After cochain, the block chain between node knows together the corresponding data of Network Synchronization extremely by block chain
Node locally completes common recognition.
S120, block height is obtained.
In this embodiment, block height is determined by the data stored in block, when being stored into new data in block,
Then the block height can change, and therefore, obtain the block height, and then judge whether block height changes, thus
Know whether that needing to carry out data synchronizes.
S130, judge whether block height changes；
S140, if so, the business datum after cochain is cached to relational database and file according to node synchronization rules
System.
The node synchronization rules refer to the principle that data are accordingly filtered and synchronized according to business rule on chain, in synchronization
Afterwards, various dimensions query function can be externally provided.
S150, it gives out information to central node.
In the present embodiment, need the data of cochain in addition to existing, there are also some data without cochain, such as json or
Person's file or image etc., then need according to application scenarios by data separating chaining, two parts under chain, for business number under chain
According to by unified message interaction API driving data be synchronized to node local data base, and support a variety of data formats (such as file,
Video etc.), it is handled up by message duration and final consistency guarantee system height, high failure tolerance.
It gives out information to central node, periodically to retract the message from central node, so that it is synchronous to carry out data.
The message issued refers to obtaining the communication packet of central node.
S160, periodically from message center pull node subscribe to message.
In the present embodiment, node subscribes to message and refers to the communication packet with business datum under chain；Specifically, pass through
It is local to node that messaging service Https interface periodically pulls subscription message from message center, and adjusts back node messages and monitor interface
Storing data.And then synchrodata can also can continue to monitor the height change situation of block in time, to guarantee that data are same
The timeliness of step.
S170, node subscription message is decrypted, to obtain business datum under chain.
S180, to synchronizing traffic data under chain to local.
By to node subscribe to message be decrypted after by business datum under corresponding chain (json/ file/image etc.) therefrom
Heart node is pulled to node local, completes the synchronization of business datum under chain.
If it is not, then returning to the step S120.
To support in a manner of same, asynchronous, more type of message and the unified API message communication of multiple data format support, to being based on
Data communication under block chain complicated business scene has carried out well packaged.And a variety of storages such as support database, file system
Mode.In addition, the distributed environment final consistency supporting interface idempotent repetitive operation that message duration characteristic is realized.It is unified
API (application programming, Application Programming Interface) interface supports the section under complicated business scene
Point communication need, node application cost of access is effectively reduced, greatly reduce exploitation complexity while, persistence characteristic with
Transactional attribute based on message height greatly improves block chain fault tolerant mechanism, in addition, its extremely low communication consumption also ensures
The height of system is handled up, and efficiently solves the problems, such as the data interaction under the magnanimity high concurrent scene based on block chain.
The method of data synchronization of above-mentioned block chain, by knowing together, algorithm will need the data block of cochain to be synchronized to node
Local account book, by unified message interaction API drive chain under synchronizing traffic data to node local data base, for different numbers
According to the different methods of synchronization is used, more type of messages, synchronization or asynchronous progress data can be carried out and synchronized, realize and be suitable for block
Data under mass data and high concurrent business scenario between chain interior joint are synchronous to be required, reach rapidly and efficiently, height handle up with
And effect highly fault tolerant.

Step S110-S180 in embodiment is similar, and details are not described herein.The following detailed description of it is increased in the present embodiment the step of
S290-S294。
S290, message monitoring situation is obtained；
S291, judge whether message monitoring succeeds；
S292, if so, updating monitored information consumption progress；
S293, if it is not, then being consumed in a manner of periodically retrying, to form information consumption implementing result；
S294, encrypt simultaneously cochain to information consumption implementing result.
Whether the business interface for calling message to monitor succeeds according to monitoring, and update message consumes progress if success, otherwise
It is consumed in a manner of periodically retrying and reaches final consistent, to obtain the information consumption implementing result of final consistency, that is, reached
To the formula of each node, and by corresponding message consumption implementing result encrypted after cochain with finishing service closed loop.
In addition, this method further include:
Obtain the heartbeat message regularly sent from member node；
