Further, block chain node device 100 is the terminal device that can run at least one block chain node, such as can be with It is computer and server etc..It is to be appreciated that the quantity for the block chain node that each block chain node device 100 can be run It can be the configuration parameter based on block chain node device to be determined, do not do any restriction herein specifically.Please referring also to scheme 2a and Fig. 2 b, Fig. 2 a is a kind of structural schematic diagram of another embodiment of decentralization storage system of the application, and Fig. 2 b is the application A kind of structural schematic diagram of another embodiment of decentralization storage system.It is provided herein in Fig. 2 a illustrated embodiment Decentralization storage system 200 includes multiple block chain node devices, specifically includes block chain node device 201, block chain link Point device 202 and block chain node device 203 can carry out between multiple block chain node devices 201,202 and 203 point-to-point logical Letter.The corresponding account of mine program is dug since every block chain node device can run at least one, i.e. every block chain node is set It is standby to run at least one block chain node, therefore the corresponding block chain node angle that ought be based on see that Fig. 2 b was illustrated goes to center Changing storage system may include multiple block chain node A, B, C and D, wherein multiple block chain node A, B, C and D can be by same One block chain node device operation is also possible to different block chain node device operations, therefore in going in other embodiments It include multiple block chain node devices in heart storage system.Run block chain link point block chain node device can be All block chain node devices of other in system are directly communicated, corresponding, any one block chain node can be in system Communication interaction is directly carried out with other block chain nodes.Wherein, the block chain node of block chain link point is run in present example Equipment is the block chain node device as described in the embodiment corresponding to Fig. 1, and every block chain node device can at least be run One block chain node.

Wherein, it should be noted that the block run in block chain node device at least one embodiment of the application Chain node is further referred to as miner in other embodiments, i.e., block chain node can also be referred to as miner.Decentralization Included all block chain nodes are sane level in rank in storage system, i.e., all block chain nodes, which can execute, to be deposited Storage task, all block chain nodes can monitor other block chain nodes execution other than removing itself according to intelligent contract and deposit The case where storage task.In another embodiment, in decentralization storage system provided herein, can also preset by One specific block chain node executes mortgage deduction task.In another embodiment, decentralization provided herein is deposited In storage system, mortgage deduction task is also possible to by removing outside currently monitored block chain node, other all nodes Deduction task is mortgaged to execute.

Before the details for illustrating method provided herein, illustrate that the first block chain node refers to that target is deducted in execution first The node of the process of file mapped underlying mortgage layer unit, the second block chain node refer to the backup for being stored with file destination Data simultaneously execute the block chain node for repairing file destination task, and the 4th block node is the node for storing file destination, third Block chain node is supervision or whether the 4th block chain node of selective examination uploads the node that the storage of corresponding file destination proves.According to The rank of each node is identical in block chain network, therefore can learn the function according to performed by node different moments not Together and the difference of reference mode, it is sequentially or simultaneously the first block chain node, the second block that some block chain node, which can be, One or more of chain node, third block chain node and the 4th block chain node.

Specifically, from the point of view of executing store tasks, each block chain node can receive other block chain nodes Monitoring, therefore can learn every in central store system (also referred to as block chain network or system, hereafter with " system " description) A block chain node can be the 4th block chain node, but can also monitor other according to each block chain node of intelligent contract Block chain node, the block chain node is also third block chain node for the block chain node monitored compared with it. Likewise, when a certain block chain node obtains the deducting file destination mapped underlying mortgage layer unit of the task, it is corresponding The block chain node be the first block chain node, while if the block chain node is also used to repair and a certain there is abnormal mesh File is marked, then the block chain node can also be the second block chain node.

Fig. 3 is referred to, Fig. 3 is a kind of flow diagram of one embodiment of control method of decentralization storage of the application. The executing subject of the method for embodiment corresponding to Fig. 3 is third block chain node, and third block chain node is to execute supervision function The node of energy, the 4th block chain node are the nodes supervised by third block chain node.

In systems, after completing to store a certain file destination, then can generate storage proves to upload each block chain node To the data-link of its own, other block chain nodes can know that the storage proves based on node synchronism in the system.And It in system, removes other than block chain node itself, other block chain nodes all have what the storage detected on its data-link proved Qualification, can also be by detecting in the storage proof or detection data chain that whether upload file destination on its data-link in institute The storage of biography proves whether that the storage for corresponding current time proves, to judge file destination that it is stored with the presence or absence of different Often.

In the embodiment of meaning shown in Fig. 3, this method comprises:

S301: the storage whether the 4th block chain node of third block chain nodal test uploads file destination proves.Third The storage whether block chain node uploads file destination by detecting the 4th block chain node proves, whether to judge file destination There are exceptions.

Wherein, whether the supervision of third block chain link dimension or the 4th block chain node of selective examination upload the storage of corresponding file destination The block chain node of proof, the 4th block chain node are file destination and by third block chain nodal test the block of storage Chain node, any block chain node can become third block chain node in systems, similarly any block chain node To be the 4th detected block chain node.Storage, which is proved to be after block chain node completes storage file destination, to be generated and is uploaded to Data chain；Storage proves separated in time to be updated after uploading for the first time, with other into system Block chain node prove the file destination corresponding to it still by the message or report of normal storage.Wherein, during storage proves The storage, which can be stored with, proves the time of the time generated either update, to prove what storage proved to other block chain nodes Timeliness.

In one embodiment, third block chain node can be generates at random according to intelligent contract, is also possible to by each A block chain link point progress block book keeping operation power competition is won determining.Third block chain node separated in time detects the 4th area The storage whether block chain node uploads file destination proves, to judge whether the file destination for being stored in the 4th block chain node is deposited In exception.Since block chain network interior joint has synchronism, therefore in other embodiments, third block chain node be can be directly It connects and whether is stored with the storage of the file destination that the 4th block chain node is stored on detection data chain and proves, and then judge The storage for whether receiving the file destination of the 4th block chain node upload proves, is also possible to by accessing the 4th block chain link Whether the data-link of point, which uploads the storage of file destination to detect the 4th block chain node, proves.

When the storage that detection obtains the 4th block chain node upload file destination proves that then judging file destination, there is no different Often；Conversely, not uploading either not no more fresh target on time when third block chain nodal test obtains the 4th block chain node The storage of file proves, then it is abnormal to judge that file destination exists.

If detection, which obtains the 4th block chain node, which does not upload the storage of file destination, proves, step can be successively executed S302 and step S303, conversely, can then execute step when the storage that detection obtains the 4th block chain node upload file destination proves Rapid S304.

S302: it is abnormal to judge that file destination exists.

When the storage of file destination that can not detect that the 4th block chain node uploads proves, or detect the 4th area Block chain node does not timely update the storage of file destination when proving, i.e., current storage proof does not have timeliness, then it represents that The file destination, which may be deleted in the 4th block chain node by malice, either to be lost, then judging file destination, there are different Often, and step S303 can be executed.

S303: distribution or triggering distribution repair file destination task to the second block chain node, while uploading file destination In the presence of the data-link of abnormal message to third block chain node, enter deduction file destination institute to trigger the first block chain link point The process of the underlying mortgage layer unit of mapping.Wherein, the second block chain node is to be stored with file destination Backup Data and final The block chain node for repairing file destination task is executed, the first block chain node is to execute to deduct file destination mapped first Mortgage the block chain node of the process of layer unit.

Further, the first block chain node includes: block chain node, the third block chain that block book keeping operation power competition is won Node itself presets the block chain node for deducting file destination mapped underlying mortgage layer unit or removes the 4th block Either block chain node other than chain node.Wherein, the first block chain node, which can be, can be based on each node of intelligent contract The block chain node that block book keeping operation power competition is won is carried out, is also possible to have whether execution the 4th block chain node of detection uploads mesh The node that the storage of file proves is marked, it can also be by preset for deducting file destination mapped first in systems The block chain node for mortgaging layer unit can also be being selected at random based on intelligent contract, remove other than the 4th block chain node Either block chain node.Wherein, intelligent contract is promise (promises) that is preset, defining in digital form, including is closed About participant (i.e. all block chain nodes) can execute the agreement of these promises above.In different embodiments, in system It may include multiple intelligent contracts, multiple intelligence contracts are correspondingly arranged with different stage mortgage layer unit, and mortgage layer unit is constituted A part of intelligent contract, due to mortgaging layer unit at least underlying mortgage layer unit in technical solution provided herein With two ranks of secondary mortgage layer unit, therefore intelligent contract also includes at least two ranks, and advanced intelligent contract also has The effect of the intelligent contract of management and calling low level.

Further, the second block chain node and the 4th block chain node can be same node, i.e., when the 4th block chain When node is stored with the Backup Data of file destination, it can be completed to repair file destination by the 4th block chain node itself.One In embodiment, file destination then will can be preferentially repaired when the 4th block chain node itself is stored with the Backup Data of file destination Task is distributed to the 4th block chain node.

When third block chain node detect file destination deposit generate when abnormal file destination exist abnormal message or The data-link of third block chain node is reported and is uploaded to, so that other block chain nodes can know according to the synchronism of node The file destination that four block chain nodes are stored exists abnormal.

When third block chain node uploads file destination and there is abnormal message to third block chain node, meeting in system The first block chain node is determined based on intelligent contract, and the first block chain node is triggered into deduction file destination and is reflected at this time The process for the underlying mortgage layer unit penetrated.It should be noted that according to the embodiment of the present application, the first block chain node be triggered into It after the process for entering to deduct file destination mapped underlying mortgage layer unit, can't execute at once, but need further to sentence It is disconnected whether to be met about the preset condition of file destination, it specifically may refer to the elaboration of following FIG. 6 to Fig. 9.

In one embodiment, it deposits when abnormal when third block chain node judges to obtain file destination, also directly divides simultaneously Match or trigger other block chain link points and is allocated reparation file destination task to the second block chain node.Wherein, it is at one In system, there may be multiple block chain nodes and be stored with the Backup Data of file destination, and finally execute reparation file destination The second block chain node of task can be based on intelligent contract in multiple block chains for being stored with file destination Backup Data It is randomly generated in node.

In another embodiment, the second block chain node is also possible to be distributed by third block chain node specified, or Be by a certain Backup Data for being stored with file destination block chain node self-recommendation go execute repair file destination task, then It is to there are multiple block chains for being stored with file destination Backup Data to be at war with and executed by the person of winning to repair file destination task. Wherein, it should be noted that in the present example, do not limit distribution or triggering distribution repairs file destination task to second There is abnormal message to the sequence of third block chain node in block chain node and upload file destination, can be and be performed simultaneously It can be and first upload file destination in the presence of abnormal message to third block chain node, can also be that first distributing or trigger distribution repairs Complicated target file task can also only upload file destination and there is abnormal message to third block chain to the second block chain node Node, does not execute distribution or the movement of file destination task to the second block chain node is repaired in triggering distribution.

Further, when file destination task to a certain block chain node is repaired in distribution, the block chain link can be first determined Whether point is stored with the Backup Data of file destination.Only judging that block chain node is stored with the Backup Data of file destination, Side can will repair file destination task and distribute to the block chain node.It is corresponding, it is understood that be only stored with target text The block chain node of the Backup Data of part just has an opportunity to become the second block chain node.

Otherwise, it when judgement obtains not having in system storing the block chain node of file destination Backup Data, is then unable to complete The reconstruction or reparation of file destination, therefore can directly terminate this node process, it executes and deducts the underlying mortgage of file destination mapped The process of layer unit.

S304: judging file destination, there is no abnormal.If third block chain node detects on the 4th block chain node The storage for having passed file destination proves, or proves according to the punctual storage for updating file destination of setting rule to data-link On, then judging file destination, there is no abnormal.It should be understood that judging file destination in third block chain node, there is no abnormal Later, third block chain node can continue the detection that next round is carried out to the 4th block chain link point, be also possible to directly terminate Current testing process.In embodiment illustrated in Figure 3, by judge file destination deposit when abnormal, distribution or triggering point With there is abnormal file destination, it can be achieved that rebuilding when repairing file destination task to the second block chain node, to reduce mortgage Deduction provides technical foundation.

Fig. 4 is referred to, Fig. 4 is a kind of flow diagram of one embodiment of control method of decentralization storage of the application, The executing subject of method illustrated in Figure 4 is third block chain node.

S401: whether the 4th block chain node of third block chain nodal test uploads file destination in the second preset time Storage prove.

Wherein, the 4th block chain node is the block chain node for storing the file destination, and the second preset time refers to The each block chain node set in centralization storage system uploads or updates storage the time interval of proof, the second preset time It is preset empirical value.Third block chain node is by detecting whether the 4th block chain node uploads mesh in the second preset time The storage of mark file proves, to judge file destination with the presence or absence of abnormal.When detecting that the 4th block chain node is default second The storage that file destination is uploaded in time proves that then judging current goal file, there is no abnormal；Conversely, when that can not detect mesh The storage of mark file proves, or detects the 4th block chain node in the second preset time of setting without more fresh target The storage of file proves, then it is abnormal to judge that file destination exists, then can execute step S402.

S402: elder generation does not execute the process for deducting file destination mapped underlying mortgage layer unit or elder generation does not notify first Block chain node executes the process for deducting file destination mapped underlying mortgage layer unit, and voluntarily judges or notify the firstth area Block chain node judges whether met about the preset condition of file destination in the first preset time.

In one embodiment, it detects that file destination is deposited when abnormal in third block chain node, then directly can voluntarily sentence Break and whether is met about the preset condition of file destination in the first preset time.

In another embodiment, third block chain node detects that file destination is deposited when abnormal, then is notified that the firstth area Block chain link point judge whether being met about the preset condition of file destination in the first preset time.Wherein, first Block chain node is the block chain node of the process of the executable underlying mortgage layer unit for deducting file destination mapping.

Wherein, preset condition includes at least file destination and is successfully repaired.Wherein, file destination is successfully repaired that refer to can It is proved with receiving the storage of target reparation file identical with file destination content.

In another embodiment, preset condition can also include: the text of file destination mapped secondary mortgage layer unit Part spoilage is less than preset threshold, and file destination is successfully repaired.Secondary mortgage layer unit is inherited out at least one and first is supported Layer unit is given as security, and the underlying mortgage layer unit either lower secondary mortgage layer unit of rank can be managed and resource tune Match.Underlying mortgage layer unit is for establishing mapping relations with the file destination stored in block chain node, it can be understood as The guarantee submitted when block chain node executes task in system.

Further, in another embodiment, judging that file destination deposits when abnormal, then third block chain node directly touches Hair enters the process for deducting file destination mapped underlying mortgage layer unit, i.e. third block chain node and the first block at this time Chain node is same node.In other embodiments, judging that file destination deposits when abnormal, it can be by third block chain node It triggers the first block chain link point and enters the process for deducting file destination mapped underlying mortgage layer unit.It should be noted that In embodiment provided herein, triggering enters the process for deducting file destination mapped underlying mortgage layer unit, and It does not execute at once, it can be in the knot for judging whether to be met about the preset condition of file destination in the first preset time Fruit, further selection executes or cancels the process for deducting file destination mapped underlying mortgage layer unit.

If preset condition is met, step S403 can be executed, otherwise can execute step S404.

S403: cancel the process for deducting file destination mapped underlying mortgage layer unit or notify the first block chain node Cancel the process for deducting file destination mapped underlying mortgage layer unit.

If it is determined that obtaining in the first preset time, when obtaining meeting about the preset condition of file destination, then can The process for deducting file destination mapped underlying mortgage layer unit is not carried out according to intelligent contract, continues next time Poll monitoring.Specifically, when the execution node that mortgage deducts is current third block chain node, then deduction can directly be cancelled The process of file destination mapped underlying mortgage layer unit；If the execution node for deducting mortgage is the first block chain node When, then it can generate command information and the first block chain node is notified to deduct without mortgage；Or be third block chain node not Know that finally which block chain node to execute mortgage by deducts, third block chain node can be sent to all block chain links at this time Point, so that executing the block chain node that mortgage deducts cancels the stream for deducting file destination mapped underlying mortgage layer unit Journey.

S404: it determines and executes the process for deducting file destination mapped underlying mortgage layer unit or notify the first block chain Node executes the process for deducting file destination mapped underlying mortgage layer unit.

If it is determined that obtaining in the case where being still unsatisfactory for preset preset condition in the first preset time, then It can be triggered according to intelligent contract and enter the process for deducting file destination mapped underlying mortgage layer unit.Specifically, third area Block chain node, which can be, is directly deducted file destination mapped mortgage, is also possible to notice and is different from third block chain link First block chain link point of point carries out mortgage deduction, realizes and provides a kind of mortgage deduction mechanism with fault tolerance, improves The enthusiasm of block chain node.

Fig. 5 is referred to, Fig. 5 is a kind of flow diagram of one embodiment of control method of decentralization storage of the application, The executing subject of method illustrated in Figure 5 is to execute the second block chain node for repairing file destination task.In present example In, this method comprises:

S501: the second block chain node obtains the Backup Data of file destination and preservation.

Wherein, the Backup Data of file destination include the initial data of file destination backup and/or file destination it is standby Part.Wherein, the second block chain node mapped underlying mortgage layer unit and the 4th block chain node mapped underlying mortgage Layer unit belongs to the secondary mortgage layer unit of at least one rank, is also possible to belong to the secondary mortgage layer list of multiple ranks Member.Such as, incorporated by reference to Fig. 8, it is assumed that the second block chain node mapped underlying mortgage layer unit is m1, the 4th block chain node institute The underlying mortgage layer unit of mapping is m3, at this time the second block chain node mapped underlying mortgage layer unit and the 4th block chain Node mapped underlying mortgage layer unit belongs to the secondary mortgage layer unit Actor1 and secondary mortgage layer list of different stage First Actor.Wherein the 4th block chain node is the block chain node for storing file destination, and secondary mortgage layer unit is underlying mortgage The higher level of layer mortgages layer unit.

Second block chain node can be the backup that file destination is obtained when the 4th block chain node executes store tasks Data are also possible to the Backup Data of the file destination obtained according to the synchronism of block chain network interior joint.Specifically, herein The mode that the second block chain node obtains the Backup Data of file destination is not limited.For the second block chain node when Obtain time and without limitation of the Backup Data of file destination, it is only necessary to can when obtaining and executing reconstruction file destination task To call to Backup Data.

S502: when receiving reparation file destination task, target is generated based on Backup Data and repairs file.Wherein, mesh It is file identical with file destination content that mark, which repairs file, it should be noted that target repairs the ID number and target text of file The ID number of part is not identical.

It further, then can be to file destination when the Backup Data of file destination is the initial data of file destination Initial data obtains target after being packaged and repairs file.

When the Backup Data of file destination is the backup of file destination, since the backup of file destination is to have completed to seal Dress but the file for not mapping to any underlying mortgage layer unit, so there is no need to the backups to file destination to be packaged, Ke Yizhi The backup that file destination is selected in selecting repairs file as target.

Further, in another embodiment, after step S502, a kind of central store of going provided herein Control method further include: repair file configuration ID number for target and upload, so that the first block chain node or other block chains Target is repaired the ID number of file to node and file destination mapped underlying mortgage layer unit establishes mapping relations.In other realities It applies in example, other block chain nodes, which are included at least, to be competed the block chain node won by block book keeping operation, preset is exclusively used in building Block chain node, the second block chain node or the 4th block chain link of vertical file destination and underlying mortgage layer unit mapping relations Point, the actual needs of concrete foundation are adjusted setting.By the way that resulting content reparation mesh identical with file destination will be repaired Mark file and file destination mapped underlying mortgage layer unit establish mapping relations, can preferably avoid depositing in file destination When abnormal, the mortgage layer unit of corresponding file destination is deducted, to improve the enthusiasm of block chain node.

S503: generating the data-link that target repairs the storage proof of file and is uploaded to the second block chain node, so that First block chain node is known and cancels the process for deducting file destination mapped underlying mortgage layer unit.

Since there are fault tolerance mechanism for method provided herein, therefore target reparation file is obtained in reparation and is stored Afterwards, the storage that file can be repaired by generating target proves and is uploaded to the data-link of the second block chain node, utilizes block chain The synchronism of node is at least so that the first block chain node has an opportunity to know that file destination is successfully repaired, so that One block chain node has an opportunity to cancel the process for deducting file destination mapped underlying mortgage layer unit.

Fig. 6 is referred to, Fig. 6 is a kind of flow diagram of one embodiment of control method of decentralization storage of the application. In the present example, the executing subject of the control method of decentralization provided herein storage is to execute mortgage and deduct to appoint First block chain node of business, this method comprises:

S601: the first block chain node monitors whether to be met about the preset condition of file destination.Wherein, first Block chain node is the block chain node for executing the process for deducting file destination mapped underlying mortgage layer unit, file destination It is to spot-check to obtain through third block chain node in the presence of abnormal file, preset condition includes at least file destination and successfully repaired.

In another embodiment, preset condition can also include: the text of file destination mapped secondary mortgage layer unit Part spoilage is less than preset threshold, and file destination is successfully repaired.Wherein, secondary mortgage layer unit is underlying mortgage layer unit Higher level mortgage layer unit, underlying mortgage layer unit is directly or indirectly inherited from secondary mortgage layer unit.Secondary mortgage layer unit It is also used to manage underlying mortgage layer unit, distributes resource or task for underlying mortgage layer unit.

In decentralization storage system (hereinafter referred system), exist when the first block chain node receives file destination Abnormal information, and when obtaining the deducting the underlying mortgage layer unit that file destination maps more of the task, the first block chain node The process for deducting file destination mapped underlying mortgage layer unit can then be entered.When the first block chain link point enters deduction target After the process of file mapped underlying mortgage layer unit, the first block chain node does not execute at once and deducts the of file destination One mortgage layer unit, and can execute step S601, and the result based on step S601 judges whether to execute and supports to file destination It gives as security and deducts process, wherein mortgage, which deducts process, refers to deduction file destination mapped underlying mortgage layer unit.First block chain Node need to monitor whether after entering the process for deducting file destination mapped underlying mortgage layer unit about file destination Preset condition met.

Further, the first block of step S601 chain node monitors whether to be expired about the preset condition of file destination Foot includes: to monitor whether that the storage for receiving target reparation file proves.Wherein, it is the second block chain node base that target, which repairs file, It repairs to obtain in the Backup Data of file destination, and file identical with file destination content.In technology provided herein In scheme, after the second block chain node is repaired to obtain target reparation file based on the Backup Data of file destination, then it can generate The storage that target repairs file proves and is uploaded to the data-link of the second block chain node, to notify in decentralization storage system Other block chain nodes be stored with target repair file, corresponding, the first block chain node can then be based on block chain link The synchronism of point knows that target identical with file destination content repairs the stored message of file.It is same due to block chain node Step property, therefore the first block chain node can be directly monitor whether to receive target reparation file storage prove；In other implementations It is also possible to access the data-link of the second block chain node in example.In the present example, file is repaired when receiving target Storage then can determine whether that file destination is successfully repaired when proving, then judges that preset condition is met.

Still further, in another embodiment, further limiting file destination and successfully being repaired within a certain period of time Step S602 can be executed, therefore step S601 includes: whether monitoring receives depositing for target reparation file in the first preset time Storage proves.Wherein, the first preset time is that the text of target transmitted by third block chain node is learnt from the first block chain node There is abnormal beginning timing in part, it is decentralization storage system for failure that the first preset time is set based on experience value The time of tolerance supports when successfully repairing file destination in the first preset time then and will not deduct file destination mapped first Give as security layer unit.

When step S601 monitors to obtain meeting about the preset condition of file destination, step S602 can be executed, it is on the contrary When the preset condition for judging file destination is not met for, step S603 can be executed.

S602: cancel the process for deducting file destination mapped underlying mortgage layer unit.

Since the second block chain node is after executing the repairing file destination of the task, obtain and file destination content phase Same target repairs file, and target can be repaired to file and can be established with file destination mapped underlying mortgage layer unit and mapped Relationship, therefore can be understood as storing file destination for whole block chain network of the task is still completed, therefore first Block chain node can then cancel the process for deducting file destination mapped underlying mortgage layer unit, i.e., will not deduct file destination Corresponding underlying mortgage layer unit.

S603: the process for deducting file destination mapped underlying mortgage layer unit is continued to execute.

If can then execute to deducting file destination mapped the conversely, when judging that preset condition is not met for The process of one mortgage layer unit, that is, remove the mortgage for deducting file destination, to punish the corresponding block chain node damage of file destination File destination.Further, when the first block chain node includes multiple, then the first all block chain nodes will continue to hold Row carries out the process of mortgage deduction to file destination, with and complete to deduct process to the mortgage of file destination.

Method provided in embodiment shown in fig. 6 is detected whether by the first block chain node about target text The preset condition of part is met, and is met if detecting about the preset condition of file destination, and deduction mesh can be cancelled Otherwise the process for marking file mapped underlying mortgage layer unit will continue to execute and deduct the underlying mortgage of file destination mapped The process of layer unit, compared with the prior art in be such as found file destination damage and execute mortgage at once and deduct, the application mentioned The technical solution of confession is after triggering mortgages and deducts process, by monitoring whether that the preset condition about file destination is expired Foot, and cancel the process for deducting file destination mapped underlying mortgage layer unit after preset condition is met, it provides Deduction mechanism is mortgaged with fault tolerance, and then improves the enthusiasm of block chain node.

Fig. 7 is referred to, Fig. 7 is a kind of process signal of another embodiment of control method of decentralization storage of the application Figure.In present example, the method comprising the steps of S701 to step S706.

In one embodiment, before executing step S701, method provided herein further include: the first block chain link Point learns that the file destination that third block chain node is sent has abnormal information.Wherein, third block chain node is detection The block chain node that the storage of file destination proves, when third block chain node detects that the storage of file destination proves that there are different File destination can be had abnormal message and is uploaded on the data-link of third block chain node by Chang Hou, the first block chain node It is abnormal can to know that file destination exists based on the synchronism of block chain node.

Further, in another embodiment, exist in the file destination for receiving the transmission of third block chain node abnormal Information while, the first block chain node will start carry out block book keeping operation power competition, with obtain execute deduct file destination institute The task of the underlying mortgage layer unit of mapping.

S701: obtaining and deduct file destination mapped underlying mortgage layer unit task, and triggers literary into target is deducted The process of part mapped underlying mortgage layer unit.

In embodiment shown in Fig. 7, the first block chain node include: block book keeping operation power competition win block chain node, Third block chain node presets block chain node for deducting file destination mapped underlying mortgage layer unit or removes the All block chain nodes other than four block chain nodes.

Wherein, the 4th block chain node is the block chain node for storing file destination.In one embodiment, storage target text The task of part is distributed from secondary mortgage layer unit to the 4th block chain node, specifically be can be and is directly distributed initial data extremely Each 4th block chain node is voluntarily packaged by the 4th block chain node and obtains file destination and store.Secondary mortgage Layer unit at least refers to the upper level mortgage layer unit of underlying mortgage layer unit, and secondary mortgage layer unit is at least used for its institute The underlying mortgage layer unit inherited out carries out Resource allocation and smoothing, the son mortgage layer unit or underlying mortgage layer list inherited out for it Member is allocated task.For 4th block chain node after storing file destination, the target that can be stored according to preset rules is literary Part sets an ID number, and ID number is uploaded, at least so that underlying mortgage layer unit distributes underlying mortgage layer list as file destination Member.

Further, it when running multiple block chain nodes in a block chain node device, then can be supported from same second Give as security the stored file destination corresponding first that layer unit inherits out all block chain nodes in the block chain node device respectively Layer unit is mortgaged, corresponding can also be that block chain node distributes new deposit in block chain node device by the secondary mortgage layer unit Storage task.Storage file destination task is otherwise allocated it should be understood that can also be in other embodiments

In one embodiment, when the first block chain node is the block chain node that block book keeping operation power competition is won, then After a certain block chain node is won in the block power of keeping accounts competes, which can obtain deduction file destination and be mapped Underlying mortgage layer unit task, become current first block chain node, corresponding first block chain node triggering, which enters, to be deducted The process of file destination mapped underlying mortgage layer unit.Enter in triggering and deducts file destination mapped underlying mortgage layer After the process of unit, the first block chain node can further determine whether to be met about the preset condition of file destination, Cancel the process for deducting file destination mapped underlying mortgage layer unit based on judging result again, or continues to execute deduction The process of file destination mapped underlying mortgage layer unit.Wherein, in the present example, preset condition includes: target text The file corruption rate of part mapped secondary mortgage layer unit is less than preset threshold, and file destination is successfully repaired.Specifically may be used Referring to step S702 to step S705.

In another embodiment, when setting, which carries out mortgage by the block chain link point of execution supervisory role, to be deducted, then the One block chain node and third block chain node are same block chain node.In the present example, when third block chain node It detects that file destination is deposited when abnormal, file destination can be had abnormal message and be sent to including third block chain node certainly All block chain nodes of body, the triggering after receiving file destination and there is abnormal message of third block chain node, which enters, to be deducted The process of file destination mapped underlying mortgage layer unit, and further judge whether the preset condition about file destination Met.

In another embodiment, when the first block chain node is to preset for deducting file destination mapped underlying mortgage The block chain node of layer unit connects when presetting the block chain node for deducting file destination mapped underlying mortgage layer unit After receiving the message that file destination has exception, deduction file destination mapped first is triggered into according to intelligent contract and is supported Give as security the process of layer unit.

In another embodiment, when the first block chain node is the either block chain link removed other than the 4th block chain node When point, it can determine that any node removed other than the 4th block chain node is the first block chain node based on intelligent contract.

S702: the first block chain node calculates file spoilage in the corresponding secondary mortgage layer unit of file destination.

Wherein, secondary mortgage layer unit is that the higher level of underlying mortgage layer unit mortgages layer unit, for managing secondary mortgage Layer, underlying mortgage layer unit are inherited from secondary mortgage layer unit.File corruption rate is secondary mortgage layer unit mapped target There is the ratio of the quantity of abnormal quantity and all file destinations of secondary mortgage layer unit mapped in file.

Refer to Fig. 8, the mortgage layer unit inheritance schematic diagram that Fig. 8 is proposed by the application, in the present example, Mortgage layer unit with inheritance can be referred to as to father and son and mortgage layer unit, in figure shown in Fig. 8, father mortgages layer unit Actor can inherit out son mortgage layer unit Actor1, sub- mortgage layer unit Actor2 and son mortgage layer unit Actor3, and son supports It gives as security layer unit Actor1 and inherits out underlying mortgage layer unit m1, m2 and m3, sub- mortgage layer unit Actor2 inherits out underlying mortgage Layer unit n1 and n2.

In this application will there is the mortgage layer unit of management and resource allocation function to be defined as secondary mortgage layer unit, it is right It answers in figure shown in Fig. 8, it is secondary mortgage layer list that the higher level of underlying mortgage layer unit m1, m2 and m3, which mortgage layer unit Actor1, Member.But in technical solution provided herein, multiple direct management or indirect control underlying mortgage layer can have The higher level of unit m1 mortgages layer unit, therefore can be corresponding with the secondary mortgage layer unit of different ranks.Such as secondary mortgage layer unit It is also secondary mortgage layer unit that the higher level of Actor1, which mortgages layer unit Actor, although mortgage layer unit Actor1 and mortgage layer list First Actor is secondary mortgage layer unit, but the rank for mortgaging management and the distribution of layer unit Actor is higher than mortgage layer list First Actor1, i.e. mortgage layer unit Actor1 can manage mortgage layer unit Actor1.

It should be noted that mortgage this integrated relationship of layer unit theoretically can integrate plurality of layers, illustrated in Figure 8 is The mortgage layer unit of three layers of inheritance, it is possible to understand that, mortgage layer unit in other embodiments may include multilayer after Relationship is held, such as may include 4 layers, 5 layers or more layers, herein and without limitation.

In the present example, underlying mortgage layer unit, which refers to, also not to have followed by son mortgage layer unit is held out The mortgage layer unit of management and distribution function, while being also the minimum mortgage layer unit of rank.Each underlying mortgage layer unit with File destination can be one-to-one, and be that underlying mortgage layer unit and target text are distributed by least one secondary mortgage layer unit Part establishes mapping relations task to underlying mortgage layer unit.After each block chain node completes storage file destination, it can correspond to The ID number that a label identity is assigned to each file destination, is at least uploaded to secondary mortgage layer unit, secondary mortgage layer for ID number Unit, can be by the ID number of each file destination and a underlying mortgage layer list not distributed after receiving the ID number of file destination Member establishes mapping relations.

Specifically, Fig. 9 is referred to, Fig. 9 is by the mapping relations between the application mortgage layer unit proposed and encapsulated layer Schematic diagram.In the present example, the memory block of the 4th block chain node encapsulation gained file destination of store tasks will be executed It is defined as encapsulated layer, in the present example, the structure of encapsulated layer can correspond to the structure of proposed mortgage layer unit, wherein by Fig. 8 is it is known that file destination S11 is corresponding with underlying mortgage layer unit m1, m3 pairs of file destination S12 and underlying mortgage layer unit It answers, file destination S13 is corresponding with underlying mortgage layer unit m2, and underlying mortgage layer unit m4 is the underlying mortgage layer list not distributed Member, D1, D2 and D3 are the backup of the initial data backup either file of file destination S11, S12 and S13.In present example Provided in technical solution in, by corresponding each file destination and underlying mortgage layer unit, preferably in fact Show and has been precisely controlled for what the mortgage of stored file destination in each block chain node deducted.

Wherein, the secondary mortgage layer unit in step S702, which refers to, does not upload first corresponding to the file destination that storage proves The higher level for mortgaging layer unit mortgages layer unit.And secondary mortgage layer unit can be the secondary mortgage layer unit across rank, such as exist In Fig. 9, the secondary mortgage layer unit of underlying mortgage layer unit m1 can refer to mortgage layer unit Actor1, may also mean that across grade Other mortgage layer unit Actor.What is calculated in step S702 is each first in the interior secondary mortgage layer unit of current slot Mortgage the probability that mapped file destination in layer unit has damage.Specifically, file corruption rate is equal in current slot Underlying mortgage layer unit mapped file destination included by secondary mortgage layer unit damages quantity and the secondary mortgage layer list The quantity ratio of all file destinations of the mapping of member.Such as, in the mortgage layer unit of meaning shown in Fig. 9, wherein each first supports It gives as security layer unit to map with a file destination, if only having underlying mortgage layer unit m1 to reflect in secondary mortgage layer unit Actor1 Penetrate file destination damage, then can the corresponding layer unit of secondary mortgage at this time Actor1 file corruption rate be equal to one third, About 33.33%, but the file corruption rate of the secondary mortgage layer unit Actor of higher level is but 1/5th, i.e., 20%.Therefore It is corresponding it is possible thereby to the secondary mortgage layer unit of different stage can be set with different file corruption rates by learning, when with Different stage mortgage layer unit is to judge then correspond to when benchmark to set different preset thresholds.

S703: judge whether file corruption rate is less than preset threshold.

Wherein, preset threshold is preset value, can be executed based on intelligent contract, preset threshold, which is intended to indicate that, to be worked as The maximum file corruption rate of mortgage layer unit acceptable of preceding mortgage layer unit either current level.It should be understood that The preset threshold, which can according to need, to be adjusted and sets, and the secondary mortgage layer unit of corresponding different stage can set difference Preset threshold.

If file corruption rate is less than preset threshold, step S704 can be executed.Conversely, when file corruption rate is greater than or equal to When preset threshold, then step S705 can be executed.

S704: execution monitors whether that the storage for receiving target reparation file proves.When file corruption rate is less than default threshold It when value, can also receive the report failed request of block chain link point according to setting the first block chain node of intelligent contract, give an event Hinder patient time to repair file destination.Within the given fault tolerance time, i.e., it can monitor whether to receive and target text The storage that the identical target of part content repairs file proves.Further, step 704 is also possible to execute to monitor and preset first The storage that target reparation file whether is received in time proves.

S705: the process for deducting file destination mapped underlying mortgage layer unit is continued to execute.When file corruption rate is big In or when being equal to preset threshold, according to setting the first block chain node of intelligent contract will not the failure that reports of recipient node ask It asks, then the first block chain node can directly execute the process for deducting file destination mapped underlying mortgage layer unit.

S706: cancel the process for deducting file destination mapped underlying mortgage layer unit.Step S706 can be found in figure 6 above The elaboration of the part step S602 in corresponding embodiment, details are not described herein.

It should be noted that when the file corruption rate of a certain secondary mortgage layer unit of previous moment is equal to preset threshold, but It is wherein to there is underlying mortgage layer unit mapped file destination in part to complete to repair after the time of setting, then at this time It is first pre- to will continue to give corresponding one fault tolerant of file destination of other underlying mortgage layer units for the secondary mortgage layer unit If the time, and execute monitoring whether received in the first preset time target repair file storage prove.
