Detailed Description
The actual scene is analyzed to find that the transaction is performed step by step, before the transaction is finally completed, a plurality of matters are confirmed and agreed step by both transaction parties, and finally the transaction is completed only by determining the rest of the matters.
Therefore, if the third party can check the document in the semi-transaction state in advance in a mode of providing the transaction document for the third party for multiple times, the transaction party only needs to continuously edit a small part of content in the document in the semi-transaction state to provide the small part of content to the third party in the transaction link, and the third party only needs to perform supplementary checking on newly edited content, so that the time can be shortened, and the processing efficiency can be improved.
However, there is no such processing mode, and the difficulty may be that a third party needs to ensure that a document provided by a transaction party later is formed by continuously modifying the original document, rather than replacing the original document with another document, and the transaction party is difficult to directly use a system of the third party to manage the document without departing from its own data system, because the third party only has a right to read the transactions but not an editing right, and the transaction document often relates to business secrets, and the transaction party has no practical meaning in directly using the system of the third party to manage the document without departing from its own data system, and the problem that the document is tampered with cannot be solved and the modified document cannot be correctly traced to the source by using a centralized system or an offline tool alone.

generating a document template using an identification based on a modifiable area, a location of the modifiable area, and corresponding variable content;
and converting the spatial point pixel information of the document template into time domain information, and constructing a traceability device by combining a time domain comparison rule and the time domain information.
6. The method according to any one of claims 1 to 5, wherein each block node verifies whether the document to be traced matches with a tracers corresponding to its designated original document, further comprising:
and performing time domain conversion on the document to be traced, and comparing the time domain conversion result of the document to be traced with the time domain information of the template document by using a time domain comparison rule.
7. The method of any of claims 1-5, wherein the modifiable region attributes comprise:
a transaction party attribute, a transaction amount attribute, a transaction deadline attribute, and a transaction contingency attribute.
8. An on-chain contract processing apparatus based on document template definition, comprising:
the transaction side block node stores the original document in a block corresponding to the random factor based on the random factor;
the traceability contract module is used for identifying a modifiable area of the original document by a construction area identification rule, defining and configuring variable content of the identified modifiable area, and constructing a traceability of the document template based on the identification of the modifiable area, the position of the modifiable area and the corresponding variable content;
adding the tracing device into a tracing contract on a block chain, associating the tracing contract with the original document, and acquiring uplink log information;
the recording module stores the uplink result log information into an index library and stores the uplink result log information into a recording linked list of the tracing contract;
the tracing contract module is further used for chaining the document to be traced by the transaction party, verifying whether the document to be traced is matched with a tracing device corresponding to the specified original document by each block node, voting, and summarizing the voting result by the block chain to obtain a tracing verification result.
9. An electronic device, wherein the electronic device comprises:
a processor; and the number of the first and second groups,
a memory storing computer-executable instructions that, when executed, cause the processor to perform the method of any of claims 1-7.
10. A computer readable storage medium, wherein the computer readable storage medium stores one or more programs which, when executed by a processor, implement the method of any of claims 1-7.
