Abstract

The invention provides a block chain data updating method and device and a readable storage medium. The block chain data updating method comprises the following steps of receiving an acquisition request of to-be-updated data, wherein the acquisition request comprises identity information of a user, acquiring the to-be-updated data from a block chain according to the identity information of the user, acquiring unique identity (ID) data of the to-be-updated data, wherein the unique identity ID data comprises an application data category to which the to-be-updated data belongs, a hash value of afirst record of the to-be-updated data on the block chain, and a hash value of a previous record of the to-be-updated data on the block chain, verifying whether the to-be-updated data is unique data or not according to the unique identity ID data, and when determining that the to-be-updated data is unique data, feeding back the to-be-updated data. The method is used for realizing data uniqueness verification, validity verification and data trajectory tracking.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular, relates to a method and device for updating data of blockchain, and a readable storage medium. Background technique [0002] In the blockchain application system, some public data is usually uploaded to the chain. In the life cycle of the application system, the public data needs to be updated over time. Due to the characteristics of the blockchain system itself, the data already on the chain cannot be To update, you need to download the original on-chain data to the local, and then re-uplink the updated data corresponding to the original on-chain data as a new data. When a user obtains public data through the blockchain application system, the system obtains the latest updated data of the user on the chain according to the user information. [0003] In the prior art, the data to be updated on the chain is obtained through the hash (Hash) address of the data on th...
