Intelligent contract data, the modification for the account book that any one node safeguards oneself will not all recognize by other nodes, thus
Guarantee that public account book can not be forged and distort.
Intelligent contract, the intelligent contract on block chain, which refers to, to be write and is compiled by solidity and operated on block chain
A string of binary codes, the calling of intelligent contract function will generate primary call on block chain and record, and in the form of transaction
It is permanently stored in block chain, we can realize data storage on block chain, read-write by intelligent contract and some patrol
Operation is collected, therefore some applications based on block chain are completed using intelligent contract.
Due to block chain data structure itself and the characteristic for algorithm of knowing together, block chain participation node, which is generally difficult to be directed to, to be write
The data for entering block chain do subsequent processing.When violation data is recorded in public chain by way of transaction, or pass through intelligence
When energy contract is written into, is stored in public chain, these violation datas are modified by government or other Gong Lian regulatory agencies, delete or shield
Covering, which all will lead to block Hash and generate, changes, and the block after change is re-started broadcast, common recognition will consume larger cost, with mesh
It is relatively difficult to achieve for preceding technology.
Summary of the invention
The purpose of the present invention is being directed to the deficiency of existing block chain technology, a kind of public chain information for not influencing confidence level is provided
Screen method.
The purpose of the present invention is be achieved through the following technical solutions: one kind not influencing the public chain information shield side of confidence level
Method, comprising the following steps:
Step 1:
Monitoring party detects the violation information being stored in transaction or intelligent contract, it is desirable that the super node or intelligence of public chain
It can contract developer shielding violation information
Step 2:
1) when violation information is stored in transaction: regulatory agency initiates transaction of the shielding containing violation information to super node
Transaction Hash, shielding request inside all super nodes complete common recognition.After super node common recognition, initiate to shield to ordinary node
The transaction of violation Transaction Information is covered, public chain participates in node and is updated to the Transaction Information in former block.
2) when violation information is stored in intelligent contract: monitoring party passes through intelligent contract address lookup intelligence contract exploitation
Person notifies intelligent contract developer to delete or shield the violation content in contract；Direction super node is supervised to initiate to prohibit
With the transaction of intelligent contract, after super node verifies monitoring party identity, the contract information for disabling of knowing together in super node.Common recognition
After the completion, super super node disables the intelligent contract containing violation information to whole node broadcasts, completes violation information shielding.
Further, in the step two, transaction includes intrinsic information and self-defined information, and intrinsic information includes handing over
Easy address, transaction acceptance address, transaction are spent, and the field that these intrinsic and content meanings of trading of transaction Hash determine is made by oneself
Adopted information includes payload, extra, and custom field, which is customized by the user, to be filled in, the uncertain field of content meaning.
Further, in the step two, when supervision direction super node initiates shielding transaction, the super of transaction is received
Node carries out transaction common recognition to other super nodes after verifying monitoring party identity.After masking operation carries out, violation information is only right
Super node is as it can be seen that only retain the Hash of violation self-defined information in the block of the ordinary node in public chain.
Further, in the step two, intelligent contract developer possesses deletion or shields the permission of violation information, screen
Violation information after covering is invisible to the caller of intelligent contract.
Further, in the step two, intelligence under the address is forbidden in the address that super node can specify intelligent contract
The calling of energy contract.
Detailed description of the invention
Fig. 1 is the process flow that the transaction of block chain has violation information；
Fig. 2 is the process flow that intelligent contract memory has violation information
Specific embodiment
Below according to the drawings and specific embodiments the present invention is described in detail, the objects and effects of the present invention will become brighter
It is aobvious.
As shown in Figure 1, the present invention handles the step in the transaction of violation information memory block chain:
1. the transaction Hash that regulatory agency initiates transaction of the shielding containing violation information to super node.
2. super node certifying organization identity, then enters step 3 after being proved to be successful, shielding process is otherwise terminated.
3. common recognition is completed in shielding request inside all super nodes, after knowing together successfully, 4 are entered step, otherwise terminates screen
Cover process.
4. super node initiates the transaction of shielding violation Transaction Information to ordinary node, public chain participates in node in former block
Transaction Information be updated, super node then retains shielding content.
As shown in Fig. 2, the present invention handles the step in violation information memory block chain intelligence contract:
1. monitoring party determines the executor for deleting violation content, notify intelligent contract developer to the violation content in contract
It is deleted or is shielded, or initiate the request of disabling contract to super node
2. super node certifying organization identity, then enters step 3 after being proved to be successful, disabling process is otherwise terminated.
3. common recognition is completed in shielding request inside all super nodes, after knowing together successfully, 4 are entered step, otherwise terminates and prohibits
