On-chain traceability method for data and data operation algorithm

Abstract

The invention provides an on-chain traceability method for data and a data operation algorithm, and belongs to the field of block chain applications and smart contracts, and the method comprises the steps of deploying a smart contract comprising an application data processing algorithm through a block chain; performing algorithm operation on specific behavior data in an application through a block chain transaction calling intelligent contract function method, recording an operation result and transaction hash called by the block chain transaction to the application, and when data generated by a specific behavior of the next application is subjected to re-operation, in this contract calling transaction, the transaction hash and the transaction result of the last contract calling operation are added; the transaction hash and the transaction result are submitted to the block chain for consensus execution; and the transaction hash and the operation result of this time are also reserved, so that jumping type association between blocks on the chain is realized for data generated by application specific behaviors and a data operation algorithm, and jumping chain traceability between blocks can be carried out according to the transaction hash recorded at the last time, so that the purposes of auditing and the like are achieved, and the traceability efficiency of related data is improved at the same time.

Description

technical field [0001] The invention relates to the fields of block chain applications and smart contracts, in particular to an on-chain traceability method for data and data operation algorithms. Background technique [0002] The distributed, traceable, and non-tamperable features of the blockchain have positive significance for many applications in real life, but at present there are only some data stored on the chain, data storage certificates, and transaction hashes and chains that do not use the blockchain. The traceability mechanism realizes the traceability of the data operation process. Moreover, the current traceability of the blockchain itself is mostly traversal traceability, and it is impossible to realize jump traceability for the same type of data, which greatly restricts the traceability efficiency. The data operation process records the changes of the data, can audit the operation of the data at a specific time point, and can analyze the historical behavior ...
