Description

Incomplete markets synchronous method, system and equipment based on block chain data

Technical field

The present invention relates to block chain technical field more particularly to a kind of incomplete markets sides of synchronization based on block chain data Method, system and equipment.

Background technique

Block chain technology is also referred to as distributed account book technology, is substantially a kind of distributed interconnection data of decentralization Library.Block chain network can be considered using the network of block chain Technical Architecture, include multiple block chain nodes in the block chain network, Either block chain node can correspond at least one block chain, and either block chain may include at least one block.

In the prior art, the application of block chain can be divided into two classes:

Publicly-owned chain: all nodes can participate in common recognition, competition book keeping operation power.Publicly-owned chain be towards masses, it is any individual or Person group can read, send transaction and transaction can obtain effective confirmation of the block chain, participate in the block chain of common recognition.Number According to open.Its main feature is that: neutrality, open, transactions velocity is slow, needs " digging mine " or similar to common recognition method, commonly uses P2P network, resist Examination property is high.

License chain: the node being only licensed could know together, compete book keeping operation power and create block, include privately owned chain, alliance All non-publicly-owned chains such as chain, enterprise's chain.Data can be openly or underground.Wherein, privately owned chain refers to write-in permission in a group Knit the block chain in hand；Alliance's chain refer to by several personal or tissues, company, government control block chain.The characteristics of permitting chain Be: transactions velocity is fast, not needing the whole network common recognition, transaction cost of " digging mine " class, low (transaction only needs several permit nodes verifyings i.e. Can)；It can examine, the mainstream of commercial application field can be occupied.

Specifically, the process of business datum cochain (being stored in block chain network) includes three phases:

1, the stage is accepted, it can be understood as the business datum to cochain is connect by a certain block chain node in block chain network It receives, and the business datum is accepted by the block chain node；

2, it knows together the stage, it can be understood as block chain node needs after accepting the business datum by block chain network In other block chain nodes participate in carrying out common recognition processing to the business datum, after business datum is by common recognition, can enter and deposit The storage stage；

3, memory phase, it can be understood as the business datum that block chain node passes through common recognition carries out cochain processing.

Common recognition method i.e. common recognition algorithm in block chain technology is realized between different blocks chain node in block chain network Establish the important method for trusting, obtaining equity.So-called common recognition method is the ballot by special joint, in a short period of time The verifying and confirmation of complete swap；To a transaction, if the incoherent multiple a nodes of interests can reach common understanding, so that it may To think that the whole network can also reach common understanding to this.A kind of data structure of the block chain as storing data in chronological order, can prop up Hold different common recognition methods.

Under different common recognition methods, the generating process of block can be slightly different.But on the whole, each node is received in processing After the block information arrived, process of exchange is substantially all according to following process: node receives multiple Transaction Informations, is put into trading pit In；Node obtains the Transaction Information being currently received from trading pit, is ranked up to transaction and executes in order；It is finished it Afterwards, node generates intact block, is finally broadcasted.

Block chain is as emerging technology, and perfect there are also many problems demands, block chain agreement is faced with the obstacle of scalability. The scaling concern of block chain is roughly divided into two aspects:

1, the extension sexual dysfunction of handling capacity of trading and trade confirmation delay；

2, sexual dysfunction is extended caused by block chain overall situation account book data storage bottleneck.

By taking this service request of block cochain in business datum as an example, in the common recognition stage, either block chain node is being received To after the request of block cochain, need to broadcast itself to this cochain from all block chain nodes other in block chain network to the whole network The signature of request, can cochain after through common recognition.It has been used in block chain existing, either publicly-owned chain is privately owned Chain or alliance's chain are all that transaction is handled on a chain, it is contemplated that block chain node is numerous, when there is common recognition demand, holds Easily lead to block chain network congestion.Such as: there is different mechanisms in certain company, and the business of these mechanisms is all such as placed on a chain On, the pressure that will cause processing business on chain increases, and the processing business time can be elongated, is unfavorable for the expansion of business.Also, in area The signature for needing to store all block chain nodes of the whole network in block, as the node on block chain is continuously increased, shared data and altogether Knowing the spent time can also be continuously increased, and cause storage burden to block in this way.

Block chain network is the network system based on distributed principle, theoretically speaking the content on each network node It is consistent, wants to obtain the data in block chain, as long as being obtained from wherein any one node or local node.

But in actual application, local node can freely configure the type of current local node.For example, can be with The full record node (full-node) comprising intact block chain data selectively is configured by local node, or includes part The non-full record node (n-full-node) of block chain data.

Which data is locally stored can be determined by current local node type and concrete configuration, therefore local node Not necessarily there are all data of intact block chain in current network in block chain.Non- full record node is configured in local node When, the data needed for carrying out needing to obtain to other nodes of place block chain network when data are synchronous, currently existing number It is difficult to realize carry out safety in above-mentioned scene according to synchronous method and efficient data is synchronous.

Thus, it needs to find a kind of new block chain synchronization scheme, to overcome the above problem.

The main thought of technical solution of the embodiment of the present invention: synchronous target block is requested to destination node；Reception is requested Target block；If received node is the non-fully node, the target block is forwarded to the complete node；Institute It states complete node to verify the received target block of institute, if by verifying, by the target block fragment and by acquisition Fragment data is stored to business chain.

It is right in conjunction with appended figures and specific embodiments in order to better understand above-mentioned technical solution Above-mentioned technical proposal is described in detail.

Embodiment one

One embodiment of the invention provides a kind of incomplete markets synchronous method based on block chain data, the block chain Including main chain and multiple business chains, the business chain includes a complete node for participating in main chain common recognition and multiple participation business chains The non-fully node of common recognition, as shown in Figure 1, the method for data synchronization can specifically include following steps:

Step S101 requests synchronous target block to destination node；

In the embodiment of the present application, this step is same to the destination node of synchronization object initiation data for business chain timing Step.Specifically, the destination node that can choose short distance sends the synchronization request to destination node；Business chain receives target section The synchrodata of point passback.

Step S102 receives requested target block；

In the embodiment of the present application, business chain can forward requested target block, the interaction by receiving interaction platform Platform can be used for receiving the establishment of item request of project initiator transmission, and create corresponding business item, when the traffic item When mesh is in operating status, which also can receive user and requests for the business processing of the business item, and according to this Business item and business processing request carry out business processing.

Wherein, which can be crowd and raises platform, then the crowd raise platform both can receive raised by the crowd that the side of raising money is sent Establishment of item request, and creates corresponding crowd and raises project, also can receive by raising request with recognizing of throwing that human hair send, this recognize raise request can To be to raise recognizing for project for the crowd in fund raising state to raise request.

In the embodiment of the present application, interaction platform externally provides docking standard agreement, specifically, each business chain network can With the Application Programming Interface (API) provided according to interaction platform, the client of built-in standard agreement is developed, is docked with interaction platform As a common recognition node.

In the embodiment of the present application, a node accepts the business of block, which can be referred to as service handling node, And initiation is to the common recognition of the business.It can also include multiple nodes, if these nodes participate in the business other than the node Common recognition processing, then these nodes can be referred to as common recognition node.In addition, these nodes can also be used as service handling node. Such as: include 5 nodes (such as: node 1, node 2, node 3, node 4 and node 5), each section in the main chain of block chain Point is either service handling node can be common recognition node again.Assuming that node 1 has accepted certain business datum, then node 1 this When be service handling node, node 2, node 3, node 4 and node 5 are then participated in as the common recognition node of the business datum to the industry The common recognition processing for data of being engaged in.

In the embodiment of the present application, what the node of the main chain of block chain can be used as business datum accepts node, can also be with Not as the node that accepts of business datum, and as the node or this complete of processing of knowing together for initiating common recognition processing Node is not specifically limited here.

If the node of the main chain of block chain accepts node as business datum, then the block chain node can be from local A part of business datum is fished for as business datum to be known together in the business datum of storage accepted, and is directed in order to subsequent The partial service data fished for initiate common recognition processing.

If complete node of the node of business chain not as the accepting node of business datum and as this common recognition processing, that The block chain node can fish for a part of business datum as industry to be known together from business datum resource pool to be known together Business data, in order to the subsequent common recognition processing initiated for the partial service data fished for.

Specifically, the node of the business chain receives the target block that interaction platform is sent, and is receiving mesh to be known together After marking block, the corresponding business datum for generating the service request to be known together is obtained.Due to user's letter as target block Breath is sent to the common recognition node, so the node is when receiving the business datum, as long as believing in the business datum comprising user Breath, can determine that the corresponding business processing data of the target block are accepted by which user side.

The target block is forwarded to described complete by step S103 if received node is the non-fully node Node.

In the embodiment of the present application, as described above, interaction platform externally provides docking standard agreement, specifically, each industry The Application Programming Interface (API) that chain network of being engaged in can be provided according to interaction platform develops the client of built-in standard agreement, with friendship Mutual platform docking becomes an externally common recognition node, referred to as complete node.It is put down in addition, any main body can also be docked to interaction Platform becomes internally common recognition node, referred to as non-fully node.

Wherein, it is described it is internal common recognition node type can be individual, enterprise, regulatory agency etc., be also possible to credit height, In credit, the different credit grade such as credit is low.In short, internally the type of common recognition node can divide according to the actual situation, this Apply without limitation.

Specifically, the client of built-in docking standard agreement can be installed at the terminal for personal or individual, with After can submit at any time service request by the client；For enterprise, the enterprise especially provided services to the user, Its application can be docked with configuration center, when it is provided services to the user, this can be submitted to service corresponding business and asked It asks, for knowing together accordingly, subsystem carries out common recognition verification.

For example, the client of certain electric business platform built-in can dock standard agreement, docked with interaction platform, when user is at this When electric business platform is done shopping, whether electric business platform request sub-network of knowing together is whether certified products, the user prop up to the purchased commodity of the user It pays the items such as successfully and carries out common recognition verification, and feed back to user.

For example, ordinary individual can become internally common recognition node, when two internally common recognition node is transferred accounts, wherein one A internal common recognition node can be with initiating business request, and requesting the corresponding region block chain network of payment technical field is this progress of transferring accounts Common recognition verification, and this corresponding block of transferring accounts is recorded on the block chain of region.

In short, application scenarios are very rich under the framework of this system, individual can become internally common recognition node, request The various events of its generation are verified, enterprise can become internally common recognition node, trust of the enhancing user to it.

In the embodiment of the present application, the non-fully node is internal node body, can be assigned in the present system internally Node body with the identity of node, but these non-fully node is that cannot participate in externally knowing together under the application scenarios of the application Verification, the external common recognition verification under the application scenarios of the application is executed by complete node.

But non-fully node can execute internally common recognition verification described in the application scenarios of the application, as described above, Entire society can be included in unified credit system based on the business chain, when the business chain corresponds to a publicly-owned block When chain network, which only needs to dock with the business chain, will not influence the publicly-owned block link network The operating of network, that is, main chain script.

Specifically, if the receiving node of the business chain is the non-fully node internally known together, by step The received target block of S102 is forwarded to the complete node externally known together.

In an alternative embodiment, the leader node that the complete node can be elected by Raft algorithm.In Raft In agreement, each node in distributed network can be divided into leader node and subordinate's node, which has to the distribution Subordinate's node in formula network sends the permission of heartbeat message, and subordinate's node in the distributed network is receiving the leader After the heartbeat message that node is sent, which can be updated in contents such as the information logs of subordinate's node local.In addition, When initiating business by subordinate's node, which can be sent to the business leader node, and by the leader node To carry out business processing, or it is distributed to other subordinate's nodes and carries out business processing.

Wherein, which can be when the block chain network brings into operation, and is elected and is produced by each internal consensus node It is raw, the specific leader node how to elect and the leader node how change-session, can be such as Raft agreement one in the prior art It causes, the application does not limit this.

Further, in the embodiment of the present application, when the distributed protocol is Raft agreement, due in Raft agreement Leader node needs each node into the network to send heartbeat message, so the common recognition node is in determining the block chain network Leader node when, which can be determined by the heartbeat message received.If the common recognition node is in heartbeat message pair When the time cycle answered is not received by the heartbeat message of leader node transmission, then the common recognition node can wait other common recognition sections Point initiates election, and receives the ballot request of candidate's node transmission, and by responding ballot request, selects the next term of office Leader node.Certainly, which can also become chooser node, and send ballot request to other common recognition nodes, then The common recognition node can also become the leader node in the block chain network.Since the determination of above-mentioned leader node belongs to existing skill Art, so specific technical detail the application repeats no more.

It should be noted that the complete node or non-fully node can be terminal, e.g., mobile phone, PC/plate electricity The equipment such as brain or the complete node or non-fully node is also possible to server, then the server can be the non-fully node Or the non-fully corresponding server of node, and the server can be an individual equipment, be also possible to have multiple devices The system of composition, as long as the equipment can be used as the non-fully node of the block chain network or non-fully node receives and the common recognition section The business datum that the corresponding interaction platform of point is sent, and there is the permission that common recognition is initiated in the block chain network, this Apply to this non-fully node or non-fully node be specially which kind of equipment this and without limitation.

Step S104, the complete node verify the received target block of institute, if by verifying, by the target Block fragment simultaneously broadcasts the fragment data of acquisition to business chain to store.It is described in detail specific as follows:

Step S1041, the preposition Hash and the complete node of the complete more received target block of node Newest block Hash it is whether consistent, if unanimously, the target block is carried out common recognition verification by the complete node, if logical Verification is crossed, then shows to pass through verifying.

As noted previously, as the user information as target block is sent to the common recognition node, so the node is receiving When to the business datum, as long as in the business datum including user information, can determine the corresponding business datum of the block be by What which user side accepted.

Specifically, firstly, by the newest block of the preposition Hash of the received target block and the complete node Unanimously whether Hash be compared, if comparison result is consistent, then it represents that the target block is newest block, such industry The data of business chain node realize data in the data of destination node and synchronize.Then, in the data of business chain node in target section On the basis of the data put realize data synchronization, common recognition verification is carried out to the target block, specifically the complete section The public key that point can be held with itself, verifies the signing messages for including in the target block, is determining the A.L.S. After breath is by verifying, further according to the content for including in the target block, the head cryptographic Hash of the target block is verified.True After the head cryptographic Hash of the fixed target block is by verifying, then it can determine the target block by verifying, i.e., target block passes through industry Business chain verifying, then can be stored in the business chain of itself using the target block as block.Wherein, verification code type can configure For the common Encryption Algorithm of various those skilled in the art or checking algorithm check code generated.

It should be noted that specifically each node carries out target block according to common recognition algorithm in block chain technical field Common recognition verification, also, the privacies such as account, transaction record of each node of block chain network Internet access, for verifying.The application Common recognition checking process and existing common recognition checking process and indistinction in embodiment, therefore will not be repeated in subsequent specification.

The target block cutting is one or more fragment datas by step S1042, and to one or more of points It is corresponding one or more target fragment datas that sheet data, which carries out random coded,.

Preferably, in order to guarantee the load balancing of each node in entire internally common recognition node set, it may be determined that node set In each node load capacity, and then can determine the number of each node current idle resource, so that it is determined that the target block is cut The quantity of the fragment data divided.

Further, in order to further increase the safety of target block, to one or more of fragment datas carry out with Machine coding.Wherein, the random coded in the embodiment of the present invention and existing random linear network encoding and indistinction, therefore rear Continuous specification will not repeat.

Step S1043 obtains the Hash of the target block and the Hash of each target fragment data, by the target area The Hash of the Hash of block and each target fragment data is broadcasted together to business chain to store.

In embodiments of the present invention, this step is mainly used for being recorded in the distribution feelings of the target block stored in business chain Condition, and establish the Hash of target block, target fragment data Hash set and target block unified resource positioning three it Between index relative, in case business chain non-fully node store target block when use.

Specifically, the complete node obtains the Hash of target block and the Hash of each target fragment data, according to each The Hash of a target fragment data forms target fragment data Hash set；Establish Hash, the target fragment data of target block The unified resource of Hash set and target block positions the index relative between table, by the Hash of target block, target fragment number It is broadcasted together to business chain according to the unified resource positioning table and index relative of Hash set and target block to store.

Step S105 receives the fragment data and by the fragment data distributed storage.It is described in detail specific as follows:

Step S1051 obtains the Hash of the target fragment data；

Since each target fragment has a unique Hash corresponding, being identified to target fragment and It distinguishes, therefore the non-fully node of business chain needs to obtain the Hash of target fragment.

Step S1052 according to the corresponding target block of Hash lookup of the target fragment data and obtains corresponding mesh Mark fragment data content；

Specifically, according to the corresponding target fragment data Hash set of the Hash lookup of target fragment data, according to target The Hash of fragment data Hash set and target block, target block unified resource positioning table between index relative, obtain The unified resource of the corresponding target block of target fragment data Hash set positions table, is positioned according to the unified resource of target block Table reads target block, and corresponding target fragment data content is obtained from target block according to target block fragmentation threshold.

Step S1053 stores the Hash of the target fragment data and the target fragment data content to described non- Business chain where complete node.

In practical applications, it is corresponding to complete first Hash in target fragment Hash set first for the node in business chain Then the storage of target fragment completes next Hash in target fragment data Hash set by other nodes in business chain The storage of corresponding target fragment data, repeatedly until whole Hash in traversal target fragment data Hash set extremely will Entire target block storage finishes.

Other of business chain, can in the same way, by the fragment after non-fully node receives the fragment data Data are stored in the business chain of itself storage as block.

The block piecemeal storage method of the embodiment of the present invention, changes the distributed storage in the prior art based on block chain The mode of used global storage carries out piecemeal storage to block using multiple nodes in business chain, can satisfy data Measure biggish block storage；In addition, block piecemeal storage method provided by the invention also improves the safety of data storage, keep away Exempt from the risk that potential block is integrally damaged under global storage mode.

Embodiment two

Step S201 requests synchronous target block to destination node；

Unlike implementation one, in the embodiment of the present application, the main chain is divided into multiple block subchains first, so It is newest in each block subchain to obtain that the destination node request of backward each block subchain synchronizes the target block Target block.

Specifically, main chain is divided into multiple block subchains that length is 256, successively request traverses each block subchain, respectively The queue number of the block of block subchain be 1-256,257-512,513-768 ..., etc..

In an alternative embodiment, also it can set other different big for the length of block subchain according to actual needs Small regular length or variable-length.

Step S202 receives requested target block；

The target block is forwarded to described complete by step S203 if received node is the non-fully node Node.

Step S204, the complete node verify the received target block of institute, if by verifying, by the target Block fragment simultaneously broadcasts the fragment data of acquisition to business chain to store.It is described in detail specific as follows:

The newest block of step S2041, the preposition Hash of the more received target block and the complete node Whether Hash is consistent, if unanimously, the target block is verified, if showing to pass through verifying by verification.

It should be noted that specifically each node carries out target block according to common recognition algorithm in block chain technical field Common recognition verification, also, the privacies such as account, transaction record of each node of block chain network Internet access, for verifying.

Step S2042, if receiving at least two target blocks, at least two target block is respectively by different institutes The transmission of block subchain node is stated, and a corresponding upper target block is identical, then according to the change at least two target block More time-sequencing at least two target block is added in the block chain where the complete node.

It can be seen from the above, when requesting synchronous target block to destination node, be the main chain is divided into first it is multiple Then block subchain synchronizes the target block to the request of the destination node of each block subchain to obtain each block Newest target block in chain.

In practical applications, there are multiple and different block subchain nodes to send respective target block to complete node simultaneously The case where occur, in this case, the head Hash for the upper block for including in the target block of different block subchain nodes Value may be identical, if node completely determines that these target blocks pass through verifying, these target blocks are stored in area During block chain, the case where branch will occur, to increase the complexity of block chain.

Thus, in embodiments of the present invention, complete node, can be according to each when receiving at least two special objective blocks The block that includes in special objective block generates the head cryptographic Hash of time and/or each special block, to each special objective block into Row sequence, and then based on obtained ranking results, the head cryptographic Hash of the upper target block for including to each special objective block with And the corresponding head cryptographic Hash of each special objective block is updated, and is stored to these special objective blocks.

The target block cutting is one or more fragment datas by step S2043, and to one or more of points It is corresponding one or more target fragment datas that sheet data, which carries out random coded,.

Step S2044 obtains the Hash of the target block and the Hash of each target fragment data, by the target area The Hash of the Hash of block and each target fragment data is broadcasted together to business chain to store.

Step S205 receives the fragment data and by the fragment data distributed storage.It is described in detail specific as follows:

Step S2051 obtains the Hash of the target fragment data；

Step S2052 according to the corresponding target block of Hash lookup of the target fragment data and obtains corresponding mesh Mark fragment data content；

Step S2053 stores the Hash of the target fragment data and the target fragment data content to described non- Business chain where complete node.
