Taking contract data of labor relationship as an example: the establishment, modification and release of the traditional labor relationship contract are managed by the employment company in a centralized way, so that contract data signed by the employment company and the employment company is not open and transparent enough, and the risk that the contract data is falsified or the employment company does not perform is possible. Therefore, it is an urgent problem to make the contract data of the employment company and the employment company public and transparent.

In order to solve the above problem, an embodiment of the present invention provides a data processing method, where the method may be applied to a block-link point device, where the block-link point device may be any node in an access block-link network, and the node may be any form of computing device, such as a server, a user terminal, and the like. In one embodiment, the blockchain node device may acquire first transaction data between a first subscriber and a 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 contract data digitally signed by the first subscriber and the second subscriber. Further, the block link point device verifies the digital signatures of the first subscriber and the second subscriber for the contract data, when the block link point device verifies the digital signatures, the block link point device performs uplink processing on the first transaction data, and sends a signing result of the contract data to the first subscriber and the second subscriber, wherein the signing result is used for indicating that the first subscriber and the second subscriber sign the contract data successfully. When the contract data is the contract data of the labor relationship, the first subscriber may refer to a employment company, and the second subscriber may refer to an employment owner. The management aiming at the contract data is realized through the block chain, the opacity of the traditional centralized management contract data is solved, and the accuracy and the reliability of the contract data in the management process are improved.

The Block Chain (Block Chain) is a Chain data structure which combines data blocks in a sequential connection mode according to a time sequence and is a distributed book which is cryptographically used for ensuring that the data cannot be tampered and forged. Multiple independent distributed nodes (i.e., block-linked node devices) maintain the same record. The blockchain technology realizes decentralization and becomes a foundation for credible digital asset storage, transfer and transaction.

Taking the block chain structure diagram shown in fig. 1 as an example, when new data needs to be written into the block chain, the data is collected into a block (block) and added to the end of the existing block chain, and the newly added block of each node is ensured to be identical through a consensus algorithm. A plurality of transaction records are recorded in each block, and the transaction records also comprise the hash (hash) value of the previous block, and all blocks store the hash value of the previous block in the way and are connected in sequence to form a block chain. The hash value of the previous block is stored in the block head of the next block in the block chain, and when the transaction data in the current block changes, the hash value of the block is changed, so that the transaction data uploaded to the block chain network is difficult to tamper, the transaction is carried out on the block chain, the transaction process is transparent, and the reliability of the transaction data is improved.

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 subscriber has deployed other contract template data based on the ID of the first subscriber. Further, if the intelligent contract is judged to be in accordance with the intelligent contract standard specification and never deployed, and the first user never deploys other contract template data, it can be determined that the intelligent contract is verified.

For example, the first subscriber may generate an intelligent contract from the labor relationship contract template content of its own 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 signing user can send a transaction to the block chain link point device in the block chain network in a signature transaction mode, after the validity of the transaction is checked to pass, a virtual machine can be called to execute the deployment of the intelligent contract, in the process of executing the deployment, the validity of the intelligent contract is checked firstly, whether the intelligent contract meets the standard specification of the intelligent contract or not is checked secondly, whether the intelligent contract is deployed or not is checked finally through the identification of the first signing user, whether the first signing user deploys other labor relation contracts or not is checked finally, if the checks pass, the address information of the intelligent contract is generated, the contract deployment result is subjected to block chain consensus, 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 signing user.

In an embodiment, after the contract template data is deployed in the blockchain network, the first subscriber and the second subscriber may respectively use their own private keys to digitally sign contract data signed by both parties, and further, the first subscriber or the second subscriber may send first transaction data to the blockchain link point device, where the first transaction data includes the digital signature of the first subscriber and the second subscriber for the contract data, the identifier of the first subscriber, the identifier of the second subscriber, the address information of the intelligent contract, and a first digest hash, where the first digest hash is a digest hash corresponding to the contract data digitally signed by the first subscriber and the second subscriber. The contract data is signed by the first subscriber and the second subscriber by using the contract template which is already deployed in the blockchain network.

Illustratively, the first subscriber is a company and the second subscriber is a business owner, the identifier of the first subscriber is a company ID, the identifier of the second subscriber is a business owner ID, the company and the business owner respectively digitally sign the contract data system with their own private keys, and the digitally signed contract data (i.e. the first transaction data) includes: and the company ID, the owner ID, the address information of the intelligent contract and the first abstract hash are used for transmitting the first transaction data to the blockchain node equipment through transaction.

S302: and the block chain node equipment verifies the digital signatures of the first subscriber and the second subscriber for the contract data.

In one embodiment, the block link node device may verify the digital signature of the first subscriber for the contract data based on the public key of the first subscriber and verify the digital signature of the second subscriber for the contract data based on the public key of the second subscriber.

In one embodiment, the first transaction data further includes verification data, and the specific manner of uplink processing of the first transaction data by the block-node device is as follows: the block chain node point equipment verifies the first transaction data based on the verification data, when the block chain node point equipment passes the verification of the first transaction data, the first abstract hash is written into an intelligent contract, block chain consensus is conducted on the intelligent contract written into the first abstract hash, when other block chain node equipment in the block chain network passes the block chain consensus of the intelligent contract written into the first abstract hash, the intelligent contract written into the first abstract hash is generated into a first block, and the first block is issued to the block chain network to which the block chain node point equipment belongs.

In one embodiment, the verification data includes an identifier of the first subscriber, an identifier 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 block chain node equipment judges whether the address information of the intelligent contract is correct or not, whether contract template data corresponding to the contract data is deployed in advance in the block chain network or not and whether the identification of the first signing user has modification authority or not. Further, if the address information of the intelligent contract is correct, contract template data corresponding to the contract data is pre-deployed in the block chain network, and the identifier of the first subscriber has a modification right, whether the second subscriber and the first subscriber have contract data in a performance state is judged based on the identifier of the second subscriber, and if not, the first transaction data is determined to be verified.

For example, when the block link node device passes the verification of the digital signatures of the first subscriber and the second subscriber for the contract data, the virtual machine may be invoked to perform the credentialing of the contract data. In the execution process, 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 the contract template data or not are checked, and if the check fails, an execution failure result is returned. And further, whether the first subscriber has the authority to modify the contract data is checked based on the identifier of the first subscriber, and if the first subscriber has no authority, an execution failure result is returned. If the modification authority exists, whether the second subscriber has a contract with the first subscriber is checked through the identifier of the second subscriber, and if the second subscriber has the contract with the first subscriber, an execution failure result is returned. And if the verification is passed, writing the first abstract hash corresponding to the contract data into the intelligent contract.
