Problems solved by technology

However, the hedging operation is actually two operations, not a specific operation in the actual sense (such as a deletion operation), which will lead to an increase in operating costs (especially when the above hedging operation is based on the public chain), and it is not convenient to integrate with other systems ( such as a database with delete operations) to coordinate

Abstract

The invention discloses an information processing method based on a blockchain, and electronic equipment, and the method comprises the steps: determining a pre-operation range in need of a first operation based on account book information recorded in an associated node in the blockchain, the first operation comprising a deletion operation; determining a target operation range of the first operation according to the pre-operation range and based on a negotiation result between associated nodes in the blockchain; traversing data blocks stored in the nodes, and determining target data in a targetoperation range in the data blocks so as to perform first operation on the target data; and according to an operation result of the first operation, re-establishing an association relationship between the data blocks. According to the method, the data blocks stored on the nodes can be flexibly deleted and the like through a negotiation mechanism among the nodes in the blockchain, so that a user can conveniently adjust the data in the blockchain and coordinate with other systems (such as a database supporting deletion operation).

Description

Technical field [0001] This application relates to the field of blockchain, and in particular to an information processing method and electronic equipment based on blockchain. Background technique [0002] Blockchain technology can realize distributed and reliable storage of data. In specific applications, data is incrementally stored on multiple nodes in the blockchain, and the secure hash function (Secure Hash Algorithm, SHA) ensures that the data in the chain cannot be tampered with. But for the blockchain (whether it is a public chain or a consortium chain), some specific operations on the data cannot be performed, such as deletion operations. If the final operation effect of a specific operation is to be achieved, a hedging method is adopted, that is, the For the transaction, the opposite transaction is used again to achieve the final operation effect of the specific operation. However, the hedging operation is actually two operations, not a specific operation in the actua...
