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 blockchain abnormal data in one embodiment of the present application, where the embodiment of the present application is applied to a case where abnormal data such as error data and illegal data stored in a blockchain network is processed, and the method is executed by a device for processing blockchain abnormal data, where the device is implemented by software and/or hardware and is specifically configured in an electronic device carrying a blockchain node.
A method for processing block chain exception data as shown in fig. 1 includes:
s101, determining the dependency data of the transaction request in the process of executing the transaction request.
The transaction request can be a transaction request in the form of an intelligent contract and/or a transaction request in the form of a field.
Where the dependent data may be data upon which the transaction request is executed. Illustratively, it may be input data and/or output data when executing a transaction request. Wherein, the input data can be carried in the transaction request and directly obtained by analyzing the transaction request; the input data or the output data may be determined by performing a pre-execution of the transaction request prior to executing the transaction request and by a result of the pre-execution.
If the transaction request is in the form of an intelligent contract, reading data of the transaction request with the dependence data in the form of the intelligent contract correspondingly; if the transaction request is a field-type transaction request, the dependency data is the input field data of the field-type transaction request. 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.
And S102, inquiring the dependent data in a shielded data list.
The shielding data list stores the corresponding relationship between the dependent data in the block chain and the shielding state in advance, and the shielding state corresponding to the dependent data can be inquired in the shielding data list according to the corresponding relationship.
For example, in order to simplify the data content stored in the masked data list, the masked data may be stored only in the masked data list, so that when the dependent data is queried in the masked data list, it indicates that the dependent data is in a masked state; when the dependent data is not searched in the masked data list, the dependent data is in an unmasked state.
It is understood that, in order to reduce the data storage amount in the mask data list, the mask data may be embodied in the mask data list in the form of identification information. Typically, the transaction identifier of the transaction data to which the abnormal dependency data belongs is stored in the mask data list instead of the dependency data, that is, the transaction identifier and the mask status are recorded in the mask data list.
Correspondingly, the dependent data is queried in the shielded data list, which may be to query the transaction identifier of the transaction data to which the dependent data belongs in the shielded data list.
Specifically, the dependent data is queried in the masked data list, so as to determine the masking state of the dependent data in the masked data list.
For example, if the dependent data is a transaction identifier corresponding to the transaction data acquired in the transaction data acquisition transaction request, if the transaction identifier is recorded in the masked data list, it is determined that the dependent data is in a masked state.
For another example, if the dependent data is input data of the intelligent contract corresponding to the kinetic energy called by the function call transaction request, the input data is transaction data stored in the block chain, and if the transaction identifier of the transaction data corresponding to the input data is recorded in the mask data list, it is determined that the dependent data is in the masked state.
For another example, if the dependent data is the block id of the white query block in the block data query transaction request, if the transaction id corresponding to the transaction data contained in the merkel tree of the block is recorded in the mask data list, it is determined that the dependent data is in the masked state.
S103, processing the transaction request according to the shielding state of the dependent data.
In an optional implementation manner of the embodiment of the present application, the transaction request is processed according to the mask status of the dependent data, which may be returning to an execution process of the transaction request to re-determine new dependent data of the transaction request if the dependent data is in the mask status.
For example, when a user a transfers a set number of blockchain circulation elements to a user B, if some non-spent circulation elements in the user a are transferred by the user C, but the user account of the user C is in a shielded state, other non-spent circulation elements unrelated to the user C need to be searched from the user a to perform a transfer transaction.
It can be appreciated that the use of masking of exception data in a masked state is achieved by actively bypassing dependent data in the masked state when processing transaction requests.
In another optional implementation manner of the embodiment of the present application, the transaction request is processed according to the mask state of the dependent data, and the transaction request may be rejected to be executed if the dependent data is in the mask state.
It can be appreciated that the use of masked packed dependent data is enabled by directly rejecting execution of the masked dependent data when processing a transaction request.
In the process of executing the transaction request, determining the dependent data of the transaction request; inquiring the dependent data in a shielded data list; the transaction request is processed according to the data dependent mask state. According to the technical scheme, the dependency data is introduced into the transaction request to serve as the basis for determining the abnormal data, the abnormal data is identified according to the query result of the dependency data in the shielding data list, different transaction requests are processed based on the identification result, the abnormal data stored in the block chain is effectively processed, and the influences on the accuracy and the legality of the data stored in the block chain, such as the irreparable error information or illegal record 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.
Furthermore, in the process of processing the abnormal data of the block chain, additionally acquiring a shielded data processing transaction request initiated based on a shielded intelligent contract; executing the shielded data processing transaction request, operating the shielded data list to generate shielded data processing transaction data, and uplink storing; wherein the operations performed on the masked data processing transaction request include: and at least one item of the masked data is added, the masked data is removed and the masked data is inquired, so that the masked data in the masked data list corresponding to the block chain is processed.
A method for processing block chain exception data as shown in fig. 2 includes:
s201, a shielded data processing transaction request initiated based on the shielded intelligent contract is obtained.
The intelligent shielding contract is used for maintaining a shielding data list or performing operations such as query by using the shielding data list.
It will be appreciated that in order to generate a transaction request that can be handled by a masking intelligence contract, the generation of a masking data processing transaction request needs to be performed based on the masking intelligence contract.
S202, executing the request for the masked data processing transaction, operating the masked data list to generate masked data processing transaction data, and uploading the masked data processing transaction data for storage.
Wherein the operations performed on the masked data processing transaction request include: at least one of adding masked data, unmasked data, and querying masked data.
In an optional implementation manner of the embodiment of the present application, if the data shielding transaction request is a data shielding transaction request; correspondingly, the operation performed on the mask data list is as follows: and adding the shielding data in the shielding data list. For example, the transaction identifier of the transaction data to which the data to be masked belongs may be added to the masked data list.
In another optional implementation manner of the embodiment of the present application, if the data transaction request is a unmasked transaction request; accordingly, the masked data manifest is operated to: unmasked data in the masked data list. For example, the transaction identifier of the transaction data to which the mask data recorded in the mask data list belongs may be deleted.
In yet another optional implementation manner of the embodiment of the present application, if the data transaction shielding request is a query transaction shielding request; correspondingly, the operation performed on the mask data list is as follows: and inquiring the shielding state corresponding to the data to be inquired through the shielding data list. For example, whether the transaction identifier of the transaction data to which the data to be queried belongs is recorded in the masked data list or not can be queried; if yes, the shielding state of the data to be inquired is the shielded state, namely the data to be inquired is the shielded data; if not, the shielding state of the data to be queried is indicated to be an unmasked state, that is, the data to be queried is not the shielded data.
In order to reduce the use permission of a user who maintains and uses the shielding data list and reduce the influence of unnecessary shielding operation on data in the block chain on the transparency of the data stored in the block chain, the voting condition of an initiating account and/or each participant of the shielding data processing transaction request can be compared and determined in the process of executing the shielding data processing transaction request, the validity of the shielding data processing transaction request is determined according to the comparison result, and only the valid shielding data processing transaction request is processed subsequently.
In an optional implementation manner of the embodiment of the present application, an initiating account for shielding a data processing transaction request may be determined, and the initiating account is compared with a set account; and if the initiating account of the data processing transaction request is the set account, confirming that the data processing transaction request is valid.
In another optional implementation manner of the embodiment of the present application, a voting condition of each participant of the data processing transaction request may also be determined; and if the voting result of each participant meets the set requirement, the request for shielding the data processing transaction is confirmed to be effective.
For example, the voting result meets the setting requirement, and may be: the ratio of the number of the support 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 the different 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 weights of different participants can be set when each blockchain node participates in the blockchain network.
Specifically, when the masked data processing transaction request is executed, the masked data to be operated needs to be determined, and the masked data list is operated based on the determined masked data to be operated, so as to generate the masked data processing transaction data, and the masked data processing transaction data is uplink stored.
For example, in the process of executing the masked data processing transaction request, when the masked data to be operated is determined, the executed transaction identifier may be obtained from the masked data processing transaction request as the masked data to be operated.
Specifically, when a data shielding transaction request is generated based on a shielding intelligent contract, a transaction identifier of transaction data to which data to be shielded belongs is added to the data shielding transaction request; correspondingly, when the block chain node processes the data processing transaction shielding request, the data processing transaction shielding request is analyzed to obtain a transaction identifier, and the obtained transaction identifier is used as the to-be-operated shielding data.
It can be understood that the precise positioning of the mask data can be realized by the mode of mask data specification, and the execution efficiency of executing the mask data processing transaction request is improved. Preferably, the specification of the masked data may be made by an administrative account that is granted a particular privilege.
For example, when the to-be-operated mask data is determined in the process of executing the mask data processing transaction request, the to-be-operated mask data may be further determined by performing screening in the block chain historical transaction data according to the mask operation condition in the mask data processing transaction request.
Specifically, when a data shielding transaction request is generated based on a shielding intelligent contract, a shielding operation condition corresponding to data to be shielded is added to the data shielding transaction request; correspondingly, when the block chain node processes the data processing transaction shielding request, the block chain node analyzes the data processing transaction shielding request to obtain a shielding operation condition; and screening the block chain historical transaction data based on the shielding operation condition, and taking the screened shielding data as the shielding data to be operated.
Wherein the operation condition is determined by the initiating account of the data processing transaction request or the voting participant of the data processing transaction request according to the requirement. Optionally, the masking operation condition may include, but is not limited to, a block height interval, or transaction data containing specified data, etc.
For example, when the masking operation condition includes a block height interval, if abnormal data corresponding to the masked data processing transaction request is first uplink stored in a 100 th block in the block chain, and a vote is initiated to each block link point by the initiating account at a 180 th block, and a vote result is required to be counted at the 200 th block; if it is determined that the abnormal data needs to be masked in the 200 th block, the transaction identifier of the transaction data to which the abnormal data belongs between the 100 th block and the 200 th block may be used as the masking data to be operated from the time of generating the abnormal data. It is understood that, in order to reduce the influence range of the masking operation in the block chain, the transaction identifier of the transaction data to which the abnormal data belongs may also be used as the masking data to be operated from the time when the data is suspected (i.e. from block 180 to block 200), or from the time when the data is determined to be abnormal (i.e. from block 200 and other blocks thereafter).
For example, when it is determined that a certain account is an abnormal account, a transaction identifier corresponding to historical transaction data of the abnormal account included in the blockchain may be designated as the mask data to be operated.
S203, determining the dependent data of the transaction request in the process of executing the transaction request.
And S204, inquiring the dependent data in a shielded data list.
S205, processing the transaction request according to the shielding state of the dependent data.
It should be noted that, S201 to S202 correspond to a process of operating on the masked data list; S203-S205 correspond to the use of the masked data list. Therefore, S203 to S205 may be executed before S201 to S202, that is, the masked data list after the previous operation is used for query; or, S203 to S205 may be executed after S201 to S202, that is, the masked data list after the current operation is used for querying, and the specific sequence of executing the two is not limited in this embodiment of the application.
In the embodiment of the application, in the processing process of abnormal data of the block chain, an obtaining operation of a shielding data processing transaction request is added, the obtained shielding data processing transaction request is executed, a shielding data list is operated to generate shielding data processing transaction data, and the shielding data processing transaction data is uplink stored, so that the updating and the use in the shielding data list are realized, and the shielding data list can meet the shielding requirements of the block chain in different time periods in the whole life cycle.
