Detailed Description

At present, people pay more attention to management of syndicated data (e.g., contract data for rental relationships, contract data for labor relationships, etc.). Wherein, take the contract data of labor relationship as an example: the traditional labor relation contract is formulated, modified and relieved by centralized management of employment companies, so that contract data signed by the employment companies and the employment companies are not sufficiently transparent, and the risk that the contract data is tampered or the employment companies are not subjected to performance exists. Therefore, making contract data disclosure made by careers and employment companies transparent is a problem that needs to be solved currently.

In order to solve the above-mentioned problems, an embodiment of the present invention provides a data processing method, which may be applied to a block link point device, where the block link point device may be any node in an access block chain network, and the node may be any type of computing device, such as a server, a user terminal, and so on. In one embodiment, the block link point device may obtain first transaction data between the first subscriber and the second subscriber, where the first transaction data includes digital signatures of the first subscriber and the second subscriber for contract data, and a first digest hash corresponding to the digitally signed contract data of the first subscriber and the second subscriber. Further, the blockchain node device checks digital signatures of the first contractor and the second contractor aiming at the contract data, when the digital signatures pass the check, the blockchain node device performs uplink processing on the first transaction data, and sends a signing result of the contract data to the first contractor and the second contractor, wherein the signing result is used for indicating that the first contractor and the second contractor sign up for the contract data successfully. When the contract data is the contract data of the labor relationship, the first subscriber may refer to an employment company, and the second subscriber may refer to an employment person. The management of contract data is realized through the blockchain, the opacity of the traditional centralized management contract data is solved, and the accuracy and the credibility of the contract data in the management process are improved.

A blockchain (blockchain) is a chained data structure in which data blocks are sequentially connected in time sequence, and cryptographically guarantees that the data is not tamperable and counterfeit. Multiple independent distributed nodes (i.e., blockchain node devices) maintain the same record. Blockchain technology enables decentralization, becoming a cornerstone for trusted digital asset storage, transfer, and transactions.

Taking the block chain structure shown in fig. 1 as an example, whenever new data needs to be written into the block chain, the data is summarized into a block (block), and is added at the end of the existing block chain, and the newly added block of each node is ensured to be identical through a consensus algorithm. Each block records a plurality of transaction records, and the transaction records contain the hash value of the previous block, and all the blocks are sequentially connected to form a block chain by storing the hash value in the previous block in the way. The hash value of the previous block is stored in the block head of the next block in the blockchain, and when the transaction data in the previous block changes, the hash value of the current block also changes, so that the transaction data uploaded to the blockchain network is difficult to tamper, the transaction process is disclosed and transparent in the blockchain, and the reliability of the transaction data is improved.

Taking a labor relationship contract scene based on an intelligent contract as an example, the contract template data is labor relationship contract template data of a first subscriber, and the first subscriber is employment company. The smart contract is a set of conventions that are defined, propagated, verified, or executed in digital form, including agreements on which contract participants may execute the conventions. Smart contracts allow trusted transactions to be made without third parties, which transactions are traceable and irreversible.

In one embodiment, the first subscriber may generate a smart contract from the labor relationship contract template content of his company that includes, in addition to the contract template data, an identification of the first subscriber (e.g., a company ID to distinguish from other companies). Further, the first subscriber may send second transaction data to a blockchain node device in the blockchain network by way of a signature transaction, the second transaction data including an intelligent contract generated based on contract template data, and a digital signature of the first subscriber for the intelligent contract.

Further, after receiving the second transaction data, the blockchain node device may first check the validity of the second transaction data, and perform uplink processing on the first transaction data after the second transaction data passes the verification. In one embodiment, the specific way of verifying the validity of the second transaction data is as follows: and the blockchain node equipment verifies the digital signature of the first subscriber aiming at the intelligent contract through the stored public key of the first subscriber.

In one embodiment, a specific implementation of the blockchain node device for performing the uplink processing on the first transaction data includes: and the block chain node equipment checks the intelligent contract in the first transaction data, performs block chain consensus on the contract deployment result when the intelligent contract check is passed, generates a block according to the intelligent contract after the contract deployment result consensus is passed by other block chain nodes in the block chain network, and issues the block to the block chain network to which the block chain node equipment belongs.

Wherein the intelligent contract includes contract template data and an ID of the first subscriber. In one embodiment, the block link point device may determine whether the smart contract meets a smart contract standard specification, determine whether the smart contract has been deployed, and determine whether the first user has deployed other contract template data based on the first subscriber's ID. Further, if the smart contract is judged to be in accordance with the smart contract standard specification, and is never deployed, and the first user is never deployed with other contract template data, the smart contract can be determined to pass the verification.

Illustratively, the first subscriber may generate a smart contract from the labor relationship contract template content of his company that includes, in addition to the contract template data, an identification of the first subscriber (e.g., a company ID to distinguish from other companies). Further, the first contractor can send a transaction to a blockchain node device in the blockchain network in a signature transaction mode, after the legitimacy of the transaction is checked, a virtual machine can be called to execute deployment of an intelligent contract, in the process of executing deployment, the legitimacy of the intelligent contract is checked firstly, whether the intelligent contract meets the standard specification of the intelligent contract is checked secondly, whether the first contractor deploys other labor relation contracts is checked finally through the identification of the first contractor, if the check passes, address information of the intelligent contract is generated, a blockchain consensus is conducted on a contract deployment result, the intelligent contract is written into an account book after the consensus is achieved, and the contract deployment result and the address information of the intelligent contract are returned to the first contractor.

In one embodiment, after the above-mentioned contract template data is deployed in the blockchain network, the first subscriber and the second subscriber may respectively digitally sign the contract data signed by both parties with their own private keys, and further, the first subscriber or the second subscriber may send first transaction data to the blockchain point device, where the first transaction data includes digital signatures of the first subscriber and the second subscriber for the contract data, an identification of the first subscriber, an identification of the second subscriber, address information of the above-mentioned smart contract, and a first digest hash, where the first digest is a hash corresponding to the digitally signed contract data of the first subscriber and the second subscriber. The contract data is obtained by signing the first contractor and the second contractor by using the contract templates which are deployed in the blockchain network.

Illustratively, the first subscriber is a company and the second subscriber is a employment, the first subscriber is identified as a company ID, the second subscriber is identified as a employment ID, the company and the employment each digitally sign the contract data system with their own private keys, and the digitally signed contract data (i.e., the first transaction data) includes: the company ID, the employment ID, the address information of the intelligent contract and the first abstract hash are transmitted to the block chain link point device through transaction.

S302: the blockchain node device verifies digital signatures of the first subscriber and the second subscriber for contract data.

In one embodiment, the block link point device may verify the digital signature of the first subscriber against the contract data based on the public key of the first subscriber and verify the digital signature of the second subscriber against the contract data based on the public key of the second subscriber. If both the digital signature and the contract data pass the verification, the digital signature verification of the first contract user and the second contract user aiming at the contract data is determined to pass.

S303: and when the digital signature verification passes, the blockchain node equipment performs uplink processing on the first transaction data, and sends a signing result of the contract data to the first contractor and the second contractor, wherein the signing result is used for indicating that the first contractor and the second contractor sign up the contract data successfully.

In one embodiment, the first transaction data further includes verification data, and the specific way for the blockchain node device to perform uplink processing on the first transaction data is as follows: the block chain link point device checks the first transaction data based on the check data, when the block chain node device checks the first transaction data, the first abstract hash is written into the intelligent contract, the block chain consensus is carried out on the intelligent contract written into the first abstract hash, when the block chain consensus of other block chain link point devices in the block chain network on the intelligent contract written into the first abstract hash passes, the intelligent contract written into the first abstract hash is generated into a first block, and the first block is issued into the block chain network to which the block chain node device belongs.

In one embodiment, the verification data includes an identification of the first subscriber, an identification of the second subscriber, and address information of the smart contract, and the block link point device verifies the first transaction data based on the verification data, including: and the blockchain node equipment judges whether the address information of the intelligent contract is correct, whether contract template data corresponding to the contract data is deployed in advance in a blockchain network, and whether the identification of the first subscriber has modification permission or not. Further, if the address information of the intelligent contract is correct, contract template data corresponding to the contract data is deployed in advance in the blockchain network, and the identifier of the first subscriber has modification authority, judging whether the second subscriber has contract data in a performance state with the first subscriber based on the identifier of the second subscriber, and if not, determining that the first transaction data is checked to pass.

For example, when the blockchain node device verifies that the digital signatures of the first subscriber and the second subscriber for the contract data pass, the virtual machine may be invoked to perform the certification of the contract data. In the execution process, firstly checking whether the address information of the intelligent contract in the first transaction data is correct or not, and whether the contract data has the deployment of contract template data or not, and if the checking fails, returning an execution failure result. Further, based on the identification of the first subscriber, whether the first subscriber has authority to modify the contract data is checked, and if the first subscriber has no authority, an execution failure result is returned. If the modification authority exists, checking whether the second subscriber has a contract with the first subscriber through the identification of the second subscriber, and if the second subscriber has the modification authority, returning an execution failure result. And if the verification passes, the first abstract hash corresponding to the contract data is written into the intelligent contract.

Further, the intelligent contracts written in the first abstract hash are subjected to blockchain consensus, after consensus is achieved, the intelligent contracts written in the first abstract hash are written in an account book, signing results are returned to the first contractor and the second contractor, and subsequent first contractor and the second contractor can inquire contract data signed by both parties in a blockchain network through the first abstract hash of the contract data.

In one implementation, the specific way of verifying whether the first subscriber has the authority to modify the contract data based on the identification of the first subscriber may be: detecting whether the identifier of the first subscriber is stored in a preset database, and if the identifier of the first subscriber is stored in the preset database, determining that the first subscriber has permission to modify the contract data; otherwise, if the identifier of the first subscriber is not stored in the preset database, it is determined that the first subscriber has no authority to modify the contract data.
