and S210, determining violation data in the block chain.
Determining violation data in a blockchain may include a variety of.
For example, the local blockchain may be detected periodically, in real time, or under a specified trigger condition, according to a detection rule, the detection rule may be predetermined and updated periodically, the specified trigger condition may be set differently according to different applications, for example, the specified trigger condition may be that a user complaint is received or a network police complaint is received, and the like. As an example, the step 1) may specifically include: data in the blockchain is detected to determine violation data in the blockchain.
Violation data determined by other blockchain nodes or third party agencies may also be received, for example. For example, as another example, the step 1) may specifically include: a violation data list is received to determine violation data in the blockchain.
The violation data may refer to non-compliant review data or non-compliant transaction data, and so forth. The provision may be a legal regulation or the like.
And S220, adding field identification to the storage address of the illegal data in the block chain. This field identification is used to indicate that the offending data has been deleted.
The storage address of the data is generally recorded in the block chain, and after the storage address is obtained through the block chain, the corresponding data is obtained through the address, so that after the illegal data is determined, the address of the illegal data stored in the block chain can be directly deleted, and the field identification is added for the storage address. The field identifier may include various forms as long as it can identify the storage address recorded in the block chain as an invalid address.
In some embodiments, the blockchain system may interface with other system systems, such as a client or a trading platform, to enable querying of data in the blockchain through the interface. The client or the trading platform can send the query request to the block chain node through a predefined interface. The query request may carry identification information of the data, such as a hash value of the data, an address of the data, or a hash value of a storage address of the data. After receiving the data query request, the blockchain node needs to determine whether the data requested by the data query request is illegal data, that is, whether the queried data corresponds to a field identifier. Based on this, the above method may further include the steps of:
step 1), receiving a data query request. The query request is used for querying target data in a block chain; the data query request may be used to query a plurality of pieces of data, and the target data may be any one of the plurality of pieces of data.
And step 2), determining whether the target data corresponds to a field identifier in the block chain.
And step 3), if the field identification is corresponded, returning a query failure response. The query failure response is used to indicate that the target data has been deleted. And if the field identification does not correspond to the target data, returning the storage address of the target data so as to acquire the target data according to the storage address of the target data.
According to the embodiment of the invention, the detected illegal data in the block chain is deleted and marked, and when the illegal data is inquired, the inquiry prohibition response is directly returned, so that the condition that the illegal data is inquired is effectively controlled, and the transmission or disclosure of the illegal data is effectively displayed, and the more effective management of the data in the block chain is realized.
