The detailed description of above-mentioned steps please refers to following second embodiments, and details are not described herein.
Second embodiment
As shown in fig.2, second embodiment of the invention proposes a kind of block chain common recognition processing method.In the present embodiment,
The execution sequence of the step in flow chart shown in Fig. 2 can change according to different requirements, and certain steps can be omitted.This
Outside, the Conventional processing steps in relation to block catenary system can be included in the present invention according to practical application scene.This method includes following
Step：
Step S10 configures the high-level node and low-level node of block catenary system.
In the present embodiment, using double-deck grade common recognition framework, the common recognition node in block catenary system is divided into low-level section
Point and high-level node.Held using strong consistency common recognition algorithm, such as practical Byzantium when wherein low-level node is known together
Method (Practical Byzantine Fault Tolerance, PBFT) is miscounted, and using weak when high-level node is known together
Consistency common recognition algorithm, such as share authorisation verification (Delegated Proof of Stake, DPoS) algorithm.The high-level
Node can be the strong High Availabitity node of preassigned M public credibility.M is odd number in the present embodiment, commonly such as 21,
31 or 101 etc..The node listing that the low-level node can be pre-established according to one is selected successively, in the node listing
Node can be predesignated, can also be to be selected by some algorithms, such as the proof that works (Proof of Work, POW)
Algorithm or other randomness algorithms.
Step S20, low-level node are packaged block and know together.
Specifically, in block chain process of exchange, when will merchandise be packaged as block after, need by several low-level sections
Point is known together, and uses strong consistency common recognition algorithm, such as PBFT at this time.In low-level knows together mechanism normal course of operation,
High-level node maintenance one can be used for participating in the node listing of low-level common recognition mechanism, and only carry out block synchronization, not influence
Low-level common recognition process.
Whether the common recognition work of step S30, high-level monitoring nodes low-level node are normal.
Specifically, since the block that high-level node can be packaged low-level node synchronizes, when high-level node is supervised
Controlling low-level node can not reach common understanding within a preset period of time, i.e., low-level node can not generate newly within a preset period of time
When block, then it is assumed that low-level know together mechanism operation exception and for a long time do not restore.If the common recognition work of the low-level node
Do not occur exception, then the low-level node continue be packaged block know together, the high-level node continue monitor low-level
The common recognition work of node.
Step S40, when occurring abnormal, high-level node initiates to replace the common recognition of low-level node.
Specifically, when low-level know together mechanism operation exception and for a long time can not restore when, high-level know together mechanism start.
The high-level node is according to the node sequence in the node listing, it is impossible to which the low-level node replacement of normal work is at can
Low-level node, and common recognition is initiated in high-level node to replacing result, weak consistency common recognition algorithm, example are used at this time
Such as DPoS algorithms.The node sequence can preassign good certain sequence, can also be to carry out node according to POW algorithms
Election, calculated result is packaged into the sequencing of block with transaction or other randomness algorithms generate and specify node
Sequentially.
Step S50, when knowing together successfully, high-level node broadcasts common recognition is as a result, replace low-level node.
Specifically, after the request for replacing low-level node is known together successfully between the high-level node, the high-level
Node initiates signature to common recognition result (replacement to low-level node), and is broadcast to all nodes of the block chain network
In, to realize the low-level node replacement that will be worked normally at available low-level node, i.e., follow-up low-level common recognition machine
System will know together between the low-level node after replacement.
Block chain common recognition processing method provided in this embodiment can be that block chain common recognition mechanism carry out layering setting, when
In the case that single layer common recognition can not normally be reached, low-level common recognition is modified by high-level common recognition, to ensure block chain
The availability of system, the business that the system of ensure that is supported can be with normal operations.
3rd embodiment
The present invention also provides another embodiments, that is, provide a kind of computer readable storage medium, the computer
Readable storage medium storing program for executing is stored with block chain common recognition processing routine 10, and the block chain common recognition processing routine 10 can be by least one place
It manages device to execute, so that at least one processor is executed such as the step of above-mentioned block chain common recognition processing method.
Through the above description of the embodiments, those skilled in the art can be understood that above-described embodiment side
Method can add the mode of required general hardware platform to realize by software, naturally it is also possible to by hardware, but in many cases
The former is more preferably embodiment.Based on this understanding, technical scheme of the present invention substantially in other words does the prior art
Going out the part of contribution can be expressed in the form of software products, which is stored in a storage medium
In (such as ROM/RAM, magnetic disc, CD), including some instructions are used so that a client (can be mobile phone, computer, electronics
Device, air conditioner or network equipment etc.) execute method described in each embodiment of the present invention.
It these are only the preferred embodiment of the present invention, be not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
