The embodiment of the invention provides a common resource data processing method based on a block chain intelligent contract, which comprises the following steps of:
step S110: a change request initiated for common resource data hosted in a blockchain is received.
For the present embodiment, the common resource data is resource data shared by at least two parties, and the common resource data includes but is not limited to: the system comprises virtual account data with public attributes, value security data entrusted by multiple parties, open source code data on a company open platform and permission level data set for partners.
For the present embodiment, the blockchain intelligent contract technology is specifically applied to an application scenario of common resource data hosting.
The blockchain is a distributed account book, and a technical scheme for maintaining a reliable database collectively in a decentralized and trust-removing mode is provided. "distributed" here is to be understood not only as a distributed storage of data, but also as a distributed recording of data, i.e. maintained jointly by system participants. Reference to a "node" is generally made to a computer in a blockchain, including cell phones, mining machines, desktop machines, servers, and the like. Each device can act as a node, each node allowing a complete copy of the database to be obtained. The nodes are based on a set of consensus mechanism, and the whole block chain is maintained together through competition calculation. The person operating a node may be a general wallet user, a miner, and multiple people collaborating. If a blockchain is to participate, a blockchain node is owned.
The intelligent contract is a set of commitments defined in a digital form, and comprises an agreement on which contract participants can execute the commitments, namely the intelligent contract is a set of agreement which can automatically execute certain manual tasks, namely the intelligent contract can be started to automatically execute contract contents when meeting preset conditions for triggering the execution of the intelligent contract.
For the present embodiment, common resource data is hosted in the blockchain in advance. Specifically, the common resource data is packaged into blocks in advance and added into a block chain, and the associated party of the common resource data is accessed into the block chain as a node of the block chain, each associated party node maintains the blocks in which the common resource data is stored together, and the block chain automatically broadcasts notification information related to the common resource data to each associated party node in the block chain. Wherein the associator is an individual or a unit or an organization associated with the common resource data. Encryption technology and decentralization characteristics in the block chain completely conform to the requirements of common resource data hosting on storage safety and transparency, common resource data can be effectively monitored, real-time broadcasting can really ensure the right of knowledge of common resource data correlation parties, the problem of information asymmetry among the correlation parties is eliminated, and potential risks of common resource data hosting are reduced.
For this embodiment, any one of the associated parties of the common resource data may initiate a change request for changing and modifying the common resource data to the blockchain, and accordingly, the blockchain may receive the change request initiated for the common resource data and sent by any one of the associated parties.
Step S120: and responding to the change request, and acquiring the digital signature of the associator of the common resource data.
For this embodiment, when the blockchain receives the change request, a notification message that one party initiates the change of the shared resource data is automatically broadcast to each associated party node in the blockchain, and meanwhile, the change content of the shared resource data is sent to each associated party of the shared resource data in response to the change request, and if the associated party agrees with the change content of the shared resource data, a digital signature is performed, and accordingly, the blockchain can obtain the digital signature of the associated party agreeing with the change content of the shared resource data.
Step S130: and judging whether the digital signature meets a preset condition for triggering the automatic execution of the intelligent contract.
For the embodiment, the intelligent contracts are written in the blockchain in advance, and preset conditions which can trigger the automatic execution of the intelligent contracts are set. When the digital signature meets a preset condition for triggering the intelligent contract to automatically execute, automatically executing the intelligent contract to change the common resource data; and when the digital signature does not meet the preset condition for triggering the automatic execution of the intelligent contract, the intelligent contract is not executed, and anyone can not change the common resource data.
Step S140: if yes, automatically executing the intelligent contract to change the common resource data.
For this embodiment, when the digital signature meets a preset condition that triggers the automatic execution of the intelligent contract, the automatic execution of the intelligent contract is triggered, and the automatic change of the common resource data is realized. Any change and use of the common resource data are automatically executed by the intelligent contract, so that human intervention can be effectively avoided.
For the embodiment, any change of the common resource data is honestly recorded in the blockchain, the changed common resource data is updated in the blockchain, and the blockchain automatically broadcasts the notification information of the change of the common resource data to each associated party node in the blockchain, so that the right to know of the associated parties of the common resource data can be ensured, the problem of information asymmetry between the associated parties is solved, and the potential risk of common resource data hosting is reduced.
According to the method for processing the shared resource data based on the intelligent contract of the block chain, provided by the embodiment of the invention, the digital signature of the associated party of the shared resource data is obtained, and the intelligent contract is automatically executed to change the shared resource data when the digital signature meets the preset condition, so that the shared resource data can be prevented from being changed under the condition that the associated party does not know, the right of knowledge of the associated party of the shared resource data is effectively ensured, the change details of the shared resource data are stored and recorded in the block chain, the traceability is strong, the illegal tampering of the shared resource data is effectively avoided, and the safety of storage and processing of the shared resource data is obviously improved.
In one embodiment, the determining whether the digital signature meets a preset condition for triggering automatic execution of the intelligent contract includes:
and judging whether the number of the relevant parties corresponding to the digital signature reaches a preset threshold value for triggering the automatic execution of the intelligent contract.
For the embodiment, a multiple signature mechanism is used as a prerequisite for automatic execution of the intelligent contract, and after the digital signature of the associated party of the shared resource data is acquired, whether the digital signature meets a preset condition for triggering automatic execution of the intelligent contract is determined, specifically, whether the number of the digital signatures reaches a preset threshold value for triggering automatic execution of the intelligent contract is determined. If the number of the digital signatures reaches a preset threshold value which triggers the intelligent contract to automatically execute, the intelligent contract is automatically executed to change the common resource data; and if the number of the digital signatures does not reach a preset threshold value for triggering the automatic execution of the intelligent contract, the intelligent contract is not executed, and anyone can not change the common resource data.
The number of the obtained digital signatures may be any specific numerical value or a numerical value calculated according to a certain proportion, and a person skilled in the art may determine the specific numerical value of the number according to actual application requirements.
For example, if the common resource data is shared by two parties, the change request of the common resource data initiated by one party needs to obtain signatures of the two parties to trigger the automatic execution of the intelligent contract.
For another example, if the common resource data is shared by a plurality of associated parties, it may be set that the initiated request for changing the common resource data requires at least more than half of the associated parties to obtain the digital signatures of all the associated parties to trigger the automatic execution of the smart contract.
In this embodiment, the digital signature of the associated party of the common resource data is obtained based on a multiple signature mechanism, so that the common resource data can be prevented from being changed under the condition that the associated party does not know, the right of awareness of the associated party of the common resource data is effectively guaranteed, and the safety of storage and processing of the common resource data is remarkably improved.
In one embodiment, the determining whether the digital signature meets a preset condition for triggering automatic execution of the intelligent contract includes:
and judging whether the number of the correlation parties corresponding to the digital signature is consistent with the total number of the correlation parties of the common resource data.
For this embodiment, a multiple signature mechanism is used as a prerequisite for automatic execution of the intelligent contract, and after a digital signature of an associated party of the shared resource data is acquired, it is determined whether the digital signature meets a preset condition for triggering automatic execution of the intelligent contract, specifically, it is determined whether the number of associated parties corresponding to the digital signature is consistent with the total number of associated parties of the shared resource data.
For this embodiment, only when the digital signatures of all the related parties of the common resource data are acquired, the intelligent contract may be automatically executed to change the common resource data, otherwise, the intelligent contract is not executed, and no one can change the common resource data.
In this embodiment, the digital signatures of all the associated parties of the common resource data are obtained based on a multiple signature mechanism, so that the common resource data can be prevented from being changed under the condition that any associated party is unknown, the right of awareness of all the associated parties of the common resource data is effectively guaranteed, and the storage and processing safety of the common resource data is remarkably improved.
In one embodiment, before automatically executing the intelligent contract to make changes to the common resource data, further comprising:
acquiring the first signature time of the digital signature and the last writing time of the intelligent contract from the block chain;
determining that the last write time is earlier than the first signature time.
For this embodiment, in order to prevent the smart contract from being illegally tampered to implement the illegal modification of the common resource data, it is determined that the signature time of all the acquired digital signatures is later than the last write time of the smart contract, and the step of automatically executing the smart contract to modify the common resource data is continued.
For this embodiment, the signature time of each acquired digital signature of each related party is recorded in the blockchain, wherein the signature time of the acquired first digital signature is the first signature time, and the signature time of the first digital signature acquired by the blockchain can be known by acquiring the first signature time of the digital signature from the blockchain. In addition, a time node in an intelligent contract writing chain is recorded in the block chain, and the last writing time of the intelligent contract is obtained from the block chain, so that the last writing time or updating time of the intelligent contract in the block chain can be known.
In an actual application scenario, the intelligent contract is generally written into the blockchain in advance, and the intelligent contract should not be updated after the blockchain starts to acquire the digital signatures of the various associators, that is, the last write time of the intelligent contract should be earlier than the first signature time of the digital signatures.
If the last write time of the smart contract is later than the first signature time of the digital signature, the smart contract is indicated to have a greater risk of being illegally tampered. It is further determined that the last write time is earlier than the first signature time before the intelligent contract is automatically executed to make changes to the common resource data, and the step of automatically executing the intelligent contract to make changes to the common resource data is executed when the last write time is earlier than the first signature time.
In this embodiment, it is further determined whether to automatically execute the intelligent contract according to the first signature time of the digital signature stored in the block chain and the last write time of the intelligent contract, so that the validity of the intelligent contract can be effectively ensured, and the security of storage and processing of common resource data is further ensured.
In one embodiment, before automatically executing the intelligent contract to make changes to the common resource data, further comprising:
acquiring the last write-in time of the intelligent contract from the block chain;
and determining that the time interval between the last writing time and the current time is greater than a preset time length.
For this embodiment, in order to prevent the smart contract from being illegally tampered to implement the illegal modification of the common resource data, the step of automatically executing the smart contract to modify the common resource data needs to be continuously executed when it is determined that the last write time of the smart contract meets the condition.
For this embodiment, a time node in an intelligent contract write chain is recorded in a blockchain, and the last write time of the intelligent contract is obtained from the blockchain, so that the last time when the intelligent contract is written or updated in the blockchain can be known.
In an actual application scenario, an intelligent contract is generally written into a block chain in advance, and the writing time of the intelligent contract generally has a certain time interval with a time node triggering the automatic execution of the intelligent contract. If the time interval between the last writing time of the intelligent contract and the current time of the intelligent contract to be automatically executed is too small, the intelligent contract is indicated to have a greater risk of being illegally tampered. Therefore, before the intelligent contract is automatically executed to change the shared resource data, it is further determined that the time interval between the last writing time and the current time is greater than a preset time duration, and the step of automatically executing the intelligent contract to change the shared resource data is executed when the time interval between the last writing time and the current time is greater than the preset time duration.
For this embodiment, the preset time duration may be a preset time duration such as 5h, 24h, 7 days, and the like, and a person skilled in the art may determine a specific value of the preset time duration according to an actual application requirement, which is not limited in the embodiment of the present invention.
In this embodiment, it is further determined whether to automatically execute the intelligent contract according to the last write time of the intelligent contract stored in the block chain, so that the validity of the intelligent contract can be effectively ensured, and the security of storage and processing of common resource data is further ensured.
