Subsequently, the blockchain node may identify key evidence information for the evidence information, where the key evidence information may include a behavior occurrence time stamp (e.g., a specification of at which time and date object B is violated), a target asset transfer amount (e.g., specific asset data to which object B should be transferred to object a), and a target contract object (e.g., object a or object B or other objects such as houses, antiques, etc.), and the blockchain node may find, from the second electronic contract, that the object B is specifically violated the term information in the second electronic contract, which is the violation data of the second electronic contract, based on the behavior occurrence time stamp, the target asset transfer amount, and the target contract object.
Fig. 3 is a flowchart of a data processing method based on a blockchain according to an embodiment of the present application. As shown in fig. 3, the data processing method may include:
step S101, a first electronic contract sent by a first user terminal is obtained, and the first electronic contract is uplink to a block chain.
In the application, the first electronic contract carries a digital signature obtained by signing the first user terminal based on a private key, after the blockchain node obtains the first electronic contract, the first electronic contract can be checked based on a public key of the first user terminal, if verification is successful, the digital signature is legal, the blockchain node can generate a block according to the first electronic contract, and the block is added into a blockchain to finish the uplink of the first electronic contract.
Step S102, obtaining second electronic contract and evidence information sent by a second user terminal, and obtaining a block containing the first electronic contract from the block chain as a target block.
In the application, the second electronic contract is copy information of the first electronic contract, and the evidence information can be additional evidence provided for any contract object in the first electronic contract, wherein the additional evidence is used for proving that another contract object in the second electronic contract violates contract regulation in the second electronic contract. If the first electronic contract is a contract signed by the object a and the object B, and the object B violates the rule of the first electronic contract, the object a may use an event that the object B violates the rule as evidence information, the object a may submit a copy contract (a second electronic contract) of the first electronic contract and the evidence information to the second user, the second user may upload the second electronic contract and the evidence information to the second user terminal, the second user terminal may send the second electronic contract and the evidence information to a blockchain node, and the blockchain node may obtain the block generated according to the first electronic contract from a blockchain as a target block.
Step S103, verifying the validity of the second electronic contract according to the target block.
In the application, the blockchain node can determine the first hash value of the first electronic contract according to the obtained target block, the blockchain node can calculate the second hash value of the second electronic contract according to the second electronic contract, the blockchain node can compare the first hash value with the second hash value, if the first hash value is the same as the second hash value, the consistency of the content of the second electronic contract with the content of the first electronic contract can be determined, the second electronic contract is not tampered, and the second electronic contract has validity.
Step S104, if the second electronic contract is effective, identifying key evidence information in the evidence information; the key evidence information includes a behavior occurrence time stamp, a target asset transfer amount, and a target contract object identification.
In the present application, the key evidence information may include a behavior occurrence time stamp, a target asset transfer amount, and a target contract object identifier, where the behavior occurrence time stamp target contract object identifier may include a contract object in a second electronic contract, for example, the contract object may be an object a or an object B or a house M or a value article N, and the behavior occurrence time stamp may be an occurrence time violating term information in the second electronic contract, and the target asset transfer amount may be asset data in the second electronic contract.
The blockchain node may obtain a general default keyword from the database, the general default keyword may be preset in advance, the general default keyword may be a text representing a time date (such as xx year xx month xx day), a text representing asset data (such as sensitive words of hundred thousand yuan, house collateral deposit, amount of delivery and the like), and a text representing an object (such as person name a, building B, article C and the like), the blockchain node may match a plurality of text fields in the evidence information according to the general default keyword, find a to-be-verified time source text, a to-be-verified asset transfer text and a to-be-verified contract object identification text matched with the general default keyword from the evidence information, and identify key evidence information of the evidence information based on the to-be-verified time source text, the to-be-verified asset transfer text and the to-be-verified contract object identification text, that is, the occurrence time stamp of the behavior, the target asset transfer amount and the target contract object identification.
Step S105, searching the default data in the second electronic contract according to the action occurrence time stamp, the target asset transfer amount and the target contract object identification.
In the present application, the default data refers to term information determined by the blockchain node in the second electronic contract based on the key evidence information, where the term information is a contract term violated by a contract object, for example, if, during a period from 2 nd of 2 months of 2017 to 2 nd of 2019, the object B in the second electronic contract needs to transfer an asset to the object a for 10 ten thousand yuan, and if the key evidence information identified by the blockchain node based on the evidence information provided by the object a is a behavior occurrence timestamp of 2019.7.5 and the target asset transfer amount is 0, it may be indicated that the object B does not transfer an asset to the object a until 5 th of 7 months of 2019, then it may be determined that the object B violates the term 3 of the second electronic contract, and the term 3 is the default data.
The blockchain node can acquire the universal default key word from the database, match a plurality of text fields of the second electronic contract according to the universal default key word, find a legal time source text, a legal asset transfer text and a legal contract object identification text which are matched with the universal default key word from the second electronic contract, and match the target contract object identification with the legal contract object identification according to the legal time source text, the legal asset transfer text and the legal contract object identification text, the blockchain node can identify a legal time interval, a legal asset transfer amount and a legal contract object identification of the second electronic contract, match the behavior occurrence time stamp with the legal time interval, determine the behavior occurrence time stamp which is outside the legal time interval as first difference data, determine the target asset transfer amount which is different from the legal asset transfer amount as second difference data, and determine the target asset transfer amount which is different from the legal asset transfer amount as second contract data, and the blockchain node can match the target contract object identification with the legal contract object identification as second contract object identification, and determine the difference data of the second contract item and the second contract item information which is different from the second contract item information, and the second contract item information which is different from the second contract item information.
As can be seen from the above, by acquiring the first electronic contract and linking the first electronic contract, the non-volatility and the non-tamper-resistance of the first electronic contract can be ensured, by acquiring the second electronic contract and the evidence information, comparing the hash value of the second electronic contract with the hash value of the first electronic contract, whether the second electronic contract is valid or not can be verified, the efficiency of verifying the contract can be improved, and in the case that the second electronic contract is valid, the key evidence information of the evidence information is identified, the key evidence information is matched with the second electronic contract, the default data can be found in the second electronic contract, and the efficiency of finding the default data can be improved.
