Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Example one

Fig. 1 is a flowchart of a method for processing block chain abnormal data in one embodiment of the present application, where the embodiment of the present application is suitable for a case where abnormal data such as error data and illegal data stored in a block chain network is processed, and the method is executed by a block chain abnormal data processing apparatus, which is implemented by software and/or hardware and is specifically configured in an electronic device that carries a block chain node.

A method for processing block chain exception data as shown in fig. 1 includes:

s101, deleting the transaction data which the abnormal data belong to as a target, wherein the abnormal data are data which are stored in a block chain.

Illustratively, the exception data may be error data or illegal data already stored in the block chain, or the like.

The transaction data to which the abnormal data belongs may be transaction data including the abnormal data, or transaction data using the abnormal data as input data and/or output data.

It can be understood that, since the stored content of each block in the block chain is usually presented in the form of transaction data item by item, in order to facilitate processing of the abnormal data in the block chain, the abnormal data is usually located in units of the transaction data to which the abnormal data belongs.

S102, deleting the data content in the target deletion transaction data, and keeping the transaction identification in the block.

Because hash calculation is performed on each piece of transaction data in the block, a hash value corresponding to the transaction data is obtained as a transaction identifier and is stored in the block. Thus, in a block, the transaction identification of the target delete transaction data associated with the exception data is included in addition to the target delete transaction data corresponding to the exception data.

Because the transaction identifier can be used for assisting operations such as query positioning of the transaction data, generation of a block header, verification of correctness or validity of the transaction data, and the like, in order to avoid synchronous deletion of the transaction identifier, a large influence is brought to the block link point when other operations are performed, and the transaction identifier of the target deleted transaction data in the block is retained while the data content in the target deleted transaction data is deleted.

In an optional implementation manner of the embodiment of the application, if the target deletion transaction data is transfer transaction data, the roll-out account information in the transfer transaction data is deleted, and the roll-in account information is reserved. The transfer-out account information may be information related to the transfer-out account, such as transfer output information, intelligent contract output information, and transaction description information.

For example, in the transfer transaction, when the user a transfers a set number of block chain circulation elements to the user B, if it is determined that the transfer transaction is abnormal data, the operation information of the set number of block chain circulation elements is transferred from the block chain account to a roll-out account (an account of the user B) in the transfer is deleted, and the operation information of the set number of block chain circulation elements is reserved from the roll-in account (an account of the user a) to the block chain account to a transfer-in account (an account of the user a), so that the block chain circulation elements owned by the roll-in account (an account of the user a) are normally deducted, which is equivalent to performing penalty on the roll-in account (an account of the user a), so as to perform penalty on illegal transfer behaviors of the roll-in account (an account of the user a).

S103, deleting marks are set for the target deleting transaction data in the block chain.

In order to effectively identify the deletion state of the target deletion transaction data and distinguish the deletion condition of the stored transaction data from the incomplete storage condition of the data (for example, in a lightweight node, only a transaction identifier is stored, and only part of the transaction data is not stored or is only stored) at the same time, a corresponding deletion flag is generally set for the target deletion transaction data in a block chain.

Illustratively, the deletion marker may be obtained by character concatenation of a set length. Wherein the delete marker may include a delete identification marked for the deleted transaction data. To ensure consistency of the stored formats in different blocks, the delete markers may also include an undelete identification that marks the transaction data that was not deleted.

It can be understood that, in order to facilitate the subsequent verification of the deletion operation of the transaction data, the deletion participant signature may also be marked in the blockchain for the operation of deleting the transaction data targeted at the same time as the deletion of the data content in the targeted deletion transaction data. The deletion participant may include at least one of a deletion initiator, a deletion executor, a deletion supervisor, and the like. Wherein the number of deletion participants is at least one.

The deleting initiator can be understood as a blockchain account which actively initiates a request to delete the abnormal data; the deletion executor can understand as the node identifier of the block chain node for performing the deletion operation of the data content in the target deletion transaction data; the deletion supervisor can be each block chain link point account authorizing the abnormal data deletion request initiated by the deletion initiator or each block chain link point account authorizing the deletion authority when the deletion executor executes the deletion operation.

In order to reduce the influence of the deleted transaction data on the normal operation of the block chain network, the valid time range can be marked for the target deletion transaction data in the block chain while deleting the data content in the target deletion transaction data, and the valid time range is used for marking the usable interval range of the deleted target deletion transaction data. Illustratively, the valid time range may be determined by the block height.

For example, when the data to be verified is firstly uplink-stored in the 100 th block in the block chain, and the data to be verified is determined to be abnormal data in the 200 th block, and the transaction request to which the abnormal data belongs is deleted, the interval range corresponding to the 100 th to 200 th blocks is used as the valid time range, and the transaction data in the range is determined to be valid when the abnormal data is represented to be used in the valid time range; at block 200 and blocks thereafter, it is determined that the transaction data associated with the exception data within the range is invalid.

It can be understood that, in order to implement the standardized management of the data stored in the block chain and implement the unification of the data formats stored in the blocks, corresponding fields may be set in the blocks in advance corresponding to the respective flag contents: a delete marker field is set for delete marker, a party marker field is set for delete party signature, and a validity time field is set for validity time range. Accordingly, at least one of the deletion flag, the deletion participant signature, and the validity time range is recorded in a set field in the data content of the target deletion transaction data.

In the embodiment of the application, the transaction data to which the abnormal data stored in the block chain belongs is used as the target to delete the transaction data; deleting the data content in the target deletion transaction data, and reserving the transaction identifier in the block; and setting a deletion mark for the target deletion transaction data in the block chain, wherein the deletion mark is used for indicating that the transaction identifier of the target deletion transaction data is valid in the verification process of the target deletion transaction data. According to the technical scheme, the data content of the transaction data to which the abnormal data belongs is deleted, the transaction identifier of the deleted transaction data is reserved, and the deletion mark is introduced to indicate that the transaction identifier corresponding to the deleted transaction data is effective, so that the abnormal data such as error information or illegal records in the block chain are physically deleted, the purpose of effectively processing the abnormal data stored in the block chain is achieved, and the influences of the irreparability of the abnormal data on the correctness and the legality of the data stored in the block chain are avoided.

Example two

Fig. 2 is a flowchart of a method for processing block chain anomaly data in the second embodiment of the present application, and the second embodiment of the present application performs optimization and improvement on the basis of the technical solutions of the foregoing embodiments.

Further, in the process of executing processing of the block chain exception data, when any transaction data stored in the block chain is verified, if the dependent data of the transaction data to be verified is identified as the target deleted transaction data and the uplink block of the transaction data to be verified is within the valid time range, the transaction data to be verified is determined to be valid, otherwise, the transaction data to be verified is determined to be invalid, so as to verify the validity of the transaction data to which the deleted exception data belongs.

A method for processing block chain exception data as shown in fig. 2 includes:

s201, deleting the transaction data by taking the transaction data to which the abnormal data belongs as a target, wherein the abnormal data is data stored in a block chain.

S202, deleting the data content in the target deletion transaction data, and keeping the transaction identification in the block.

S203, setting a deletion mark for the target deletion transaction data in the block chain.

S204, when any transaction data stored in the block chain is verified, judging whether the dependent data of the transaction data to be verified is the target deletion transaction data or not; if so, S205 is executed, otherwise, S208 is executed.

It should be noted that, when a node in the blockchain network needs to synchronize data stored in the blockchain (for example, a new blockchain link point is added to the blockchain network, or a lightweight node acquires blockchain data from all nodes), data acquired from other blockchain nodes needs to be verified to verify the validity of the acquired data.

When any transaction data stored in the block chain is verified, if the identified to-be-verified transaction data is realized depending on the target deletion transaction data, for example, the target deletion transaction data is input data in the process of forming the to-be-verified transaction data, the data content of the target deletion transaction data is deleted and cannot be acquired, and the verification process of the to-be-verified transaction data cannot be performed by adopting a conventional verification mode.

In order to avoid the above situation, it is necessary to first determine whether the transaction data to be verified is the target deletion transaction data, so as to screen the target deletion transaction data from the block chain.

The dependent data may be data depended on when executing a transaction request corresponding to the transaction data to be verified. Illustratively, it may be input data when executing a transaction request. The input data can be carried in the transaction request and directly obtained by analyzing the transaction request. Wherein the transaction request can be obtained from the corresponding transaction data.

Illustratively, read data of the transaction request in the form of an intelligent contract can be acquired from the transaction request of the transaction data to be verified as dependent data; or optionally, the input field data of the transaction request in the form of a field may also be obtained from the transaction request of the transaction data to be verified as the dependency data. For example, when the transaction request is an unspent transaction output (UTXO), the input field data may be an input account address and/or an output account address, respectively.

For example, the transaction request may be a transaction data acquisition transaction request, and correspondingly, the dependency data may be a transaction identifier corresponding to the acquired transaction data. For another example, the transaction request may be a function call transaction request, and accordingly, the dependency data may be input data of the smart contract corresponding to the called function. For another example, the transaction request may be a block data query transaction request, and correspondingly, the dependency data may be a transaction identifier of each transaction data included in the queried block.

In an optional implementation manner of the embodiment of the application, it is determined whether the dependency data of the transaction data to be verified is identified as the target deletion transaction data, it may be determined whether the dependency data of the transaction data to be verified is the transaction data, and when the dependency data is the transaction data, it is read whether the dependency data has a deletion flag, and if the dependency data has the deletion flag, it is indicated that the dependency data is the target deletion transaction data; or if the dependent data has the deletion marker and the marker information of the read deletion marker is the deletion identifier, indicating that the dependent data is the target deletion transaction data.

S205, judging whether the uplink block of the transaction data to be verified is within the valid time range; if so, perform S206, otherwise perform S207.

When the uplink block of the transaction data to be verified is within the valid time range, it indicates that although the dependent data of the transaction data to be verified is the deleted target deletion transaction data, the target deletion transaction data is not deleted yet when the transaction data to be verified uses the target deletion transaction data, and the target deletion transaction data can be successfully acquired and used. However, since the dependent data itself cannot be acquired in the verification process, the transaction data to be verified can be directly considered to be valid subsequently, that is, the transaction identifier directly receiving the transaction data is correct, and the correctness of the transaction data is no longer verified by executing the transaction request.

When the uplink block of the transaction data to be verified is not in the valid time range, it indicates that the dependency data used in processing the transaction request of the transaction data to be verified, that is, the target deletion transaction data is deleted, and accordingly the use of the target deletion transaction data is limited, and it is obviously not reasonable to use the target deletion transaction data in the generation process of the transaction data to be verified, so that the transaction data to be verified can be directly considered invalid subsequently.

S206, determining that the transaction data to be verified is valid.

And S207, determining that the transaction data to be verified is invalid.

And S208, verifying the transaction data to be verified by adopting the mode of the prior art.

Because the dependent data of the transaction data to be verified is not the deleted target deleted transaction data, the transaction request of the transaction data to be verified can be directly processed, the hash value of the transaction data obtained by processing is compared with the transaction identifier of the transaction data to be verified, if the comparison result is consistent, the transaction data to be verified is determined to be valid, and otherwise, the transaction data to be verified is determined to be invalid.

According to the method and the device, when the validity of the transaction data is verified in the block chain with abnormal data, and the verification process relates to the target deletion transaction data, the transaction data to be verified corresponding to the target deletion transaction data of the uplink block in the valid time range is defaulted to be valid, so that the situation that the verification cannot be performed due to the fact that the target deletion transaction data are deleted is avoided, and a verification mechanism of other transaction data related to the deleted transaction data is perfected.

EXAMPLE III

Fig. 3A and fig. 3B are flowcharts of a method for processing block chain anomaly data in a third embodiment of the present application, and the embodiment of the present application performs optimization and improvement on the basis of the technical solutions of the above embodiments.

Further, the operation of ' deleting the transaction data to which the abnormal data belongs as the target transaction data ' is refined into ' acquiring a data deletion notification or a data deletion transaction request initiated by a set supervisory user; and determining target deleted transaction data according to the screening condition of the abnormal data in the data deletion notice or the data deletion transaction request, the content of the abnormal data or the transaction identifier of the transaction data to which the abnormal data belongs, so as to enrich the determination mode of the target deleted transaction data.

A method for processing block chain exception data as shown in fig. 3A includes:

S301A, acquiring a data deletion notice or a data deletion transaction request initiated by a setting supervisory user.

S302A, determining the target deleted transaction data according to the screening condition of the abnormal data in the data deletion notice or the data deletion transaction request, the content of the abnormal data or the transaction identifier of the transaction data to which the abnormal data belongs.

And the abnormal data is data which is stored in a block chain. The supervising user can be at least one specific account in the whole block chain network, and is used for supervising, managing, even controlling and the like the building and using processes of the block chain network. Typically, the administrative user is typically specified at the beginning of the building of the blockchain network, or before the building of the blockchain network. For example, the administrative user may be a user account with public trust.

In an optional implementation manner of the embodiment of the present application, the supervising user may send the data deletion notification through offline; correspondingly, the block link point acquires the data deletion notification sent offline, and determines the target deletion transaction data based on the data deletion notification, so as to limit the range of the data to be deleted subsequently.

In another optional implementation manner of the embodiment of the present application, in order to facilitate subsequent verification of deletion operation of abnormal data, a data deletion transaction request may also be initiated in the blockchain network by a supervisory user; correspondingly, the block chain node acquires the data deleting transaction request, and determines the target deleting transaction data based on the data deleting transaction request, so as to limit the range of the data to be deleted subsequently.

It can be understood that, in order to facilitate the determination of the target deletion transaction data, the administrative user generally adds the abnormal data association information to the initiated data in the data deletion notification or the data deletion transaction request, so that when the block link node receives the data deletion notification or the data deletion transaction request, the block link node obtains the corresponding abnormal data association information by analyzing the received data, thereby determining the target deletion transaction data according to the obtained abnormal data association information. The abnormal data association information comprises at least one of a screening condition of the abnormal data, content of the abnormal data, a transaction identifier of the transaction data to which the abnormal data belongs, and the like.

Illustratively, when the associated information includes a filtering condition for abnormal data, the included filtering condition may include, but is not limited to, a block height interval, or transaction data including specified data, or the like. For example, the transaction data defined within the block height interval by the block height interval is abnormal data; as another example, a certain data is specified, and the transaction data containing the specified data is defined as anomalous data.

S304, deleting the data content in the target deletion transaction data, and keeping the transaction identification in the block.

S305, setting a deletion mark for the target deletion transaction data in the block chain.

Wherein the delete marker is used to indicate that the transaction identifier of the target delete transaction data is valid during the validation process of the target delete transaction data.

It can be understood that, in order to define the usable range of other transaction data associated with abnormal data that is not deleted in the block chain, reduce the influence of a large amount of deletion of abnormal data on the overall integrity of the stored content of the block chain, and also define the valid time range of the target deleted transaction data.

Optionally, when the administrative user generates the data deletion notification or the data deletion transaction request, the administrative user may delete the valid time range of the transaction data of the present price target in the data deletion notification or the data deletion transaction request; accordingly, a chunk chain node may obtain a specified validity time range from a data delete notification or data delete transaction request.

The method and the device have the advantages that the supervision user sends the data deletion notification or the data deletion transaction request to trigger the abnormal data processing, and the target deletion transaction data is determined based on the screening condition of the abnormal data in the data deletion notification or the data transaction request initiated by the supervision user, the content of the abnormal data or the transaction identifier of the transaction data to which the abnormal data belongs, so that the determination mode of the target deletion transaction request is enriched, and different optional channels are provided for the supervision user to delete the abnormal data.

In order to avoid centralization of the block chain network supervision process and influence on the openness and transparency of data stored in the block chain, a plurality of users can be used as voting participants to vote on abnormal data deletion. For example, S301A to S302A in the above embodiment may be replaced with S301B to S303B to achieve the above object.

As shown in fig. 3B, a method for processing block chain exception data includes:

S301B, acquiring a data deletion voting transaction request initiated by a user.

The user initiating the data deletion voting transaction request may be any user in the blockchain network, or may be a supervising user.

Specifically, a user initiates a data deletion voting transaction request to a block link network; accordingly, the blockchain node receives and processes the data deletion voting transaction request.

It will be appreciated that in order to facilitate the voting participant users in the blockchain to know the relevant information of the pre-deleted data, the users will typically add abnormal data relevant information in the data deletion voting transaction request. The abnormal data association information comprises at least one of a screening condition of the abnormal data, content of the abnormal data, a transaction identifier of the transaction data to which the abnormal data belongs, and the like.

It should be noted that, in order to facilitate the voting participation user to respond to the voting in time, the voting deadline may also be carried in the data deletion voting transaction request. Of course, in order to clarify the coverage of the voting participation users, the account information of each voting participation user can be added to the data deletion voting transaction request.

S302B, determining the target deleted transaction data according to the screening condition of the abnormal data in the data deletion voting transaction request, the content of the abnormal data or the transaction identification of the transaction data to which the abnormal data belongs.

And the abnormal data is data which is stored in a block chain.

And the block chain node determines target deleted transaction data according to the screening condition of the abnormal data in the received data deletion voting transaction request, the specified content of the abnormal data or the transaction identifier of the abnormal data in the transaction data so as to define the range of the data to be deleted subsequently. Correspondingly, the voting participation user can vote according to the determined target deletion transaction data so as to support or object the validity of the target deletion transaction data corresponding to the deletion operation.

S303B, determining validity of the target deletion transaction data according to the voting result of the block link point for the data deletion voting transaction request.

Illustratively, the block chain node collects the voting conditions of all voting participation users, and if the voting result meets the set requirement, the target deletion transaction data is determined to be valid; otherwise, the target delete transaction data is determined to be invalid.

Optionally, the voting result meets the setting requirement, which may be: the ratio of the number of supported votes to the total number of votes satisfies a set proportion threshold. Or, optionally, the voting result meets the setting requirement, and may also be: presetting voting weights of different participants, determining a final voting result according to the product of the voting conditions of different voting participants and the voting weights, and determining that the voting result meets the set requirement if the final voting result meets the set proportion threshold. The setting proportion threshold value can be set by a block chain creator in the initial stage of block chain creation according to needs; the voting weight of different voting users can be set when each block chain link point participates in the block chain network.

S305, setting a deletion mark for the target deletion transaction data in a block chain;

Alternatively, when determining the validity of the target deletion transaction data for the voting result of the data deletion voting transaction request, the block link node may determine, as the valid time range, a block before the voting result validation block of the data deletion voting transaction request.

For example, if abnormal data corresponding to the data deletion voting transaction request is firstly uplink-stored in the 100 th block in the block chain, and a user starts voting to each block chain link point in the 180 th block, and statistics of voting results is required in the 200 th block; if it is determined that abnormal data needs to be masked at the 200 th block, it is determined that a block before the 200 th block is determined as a valid time range. Of course, in order to reduce the storage amount of the abnormal data or other data depending on the abnormal data in the block chain, the block before the data is questioned (i.e. the 180 th block) may be determined as the valid time range; or determining the block before the first ul storage of data (i.e., 100 th block) as the valid time range.

According to the technical scheme, the user initiates a data deletion voting transaction request, triggers abnormal data processing, and determines the target deletion transaction data based on screening and training of the abnormal data in the data deletion voting transaction request initiated by the user, the abnormal data content or the transaction identifier of the transaction data to which the abnormal data belongs, so that the determination mode of the target deletion transaction request is enriched, and the determination of the target deletion transaction data is performed in a voting mode, so that the subsequent deletion operation of the target deletion transaction data is public and transparent, and the possibility of abnormal data deletion is provided for each participating user of the block link network.
