Abstract

The invention provides a block chain-based multi-granularity data processing method, system and device, and a storage medium. The method comprises the following steps of receiving stored business databy a block chain node, and determining a data attribute of the business data; if the data attribute of the business data is a rich text type, storing the data in the block chain node; if the data attribute of the business data is a picture type, storing the data in a private storage cloud, and creating second navigation information of a storage path of the business data of the picture type in theprivate storage cloud by the block chain node; and if the data attribute of the business data is a video type, storing the data in a public storage cloud, and creating third navigation information ofa storage path of the business data of the video type in the public storage cloud by the block chain node. A multi-granularity non-structured data trusted storage scheme is introduced for data processing granularity through automatic judgment of the data type, thereby achieving balance between security and performance or expense.

Description

technical field

[0001] The present invention relates to the field of blockchain, in particular, to a multi-granularity data processing method, system, device and storage medium under the blockchain. Background technique

[0002] In 2008, a scholar named "Satoshi Nakamoto" published the paper "Bitcoin: A Peer-to-Peer Electronic Cash System", laying the foundation for blockchain technology. In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures a non-tamperable and non-forgeable distributed ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate update data, uses cryptography to ensure data transmission and party security, and uses automated script codes to A new distributed infrastructure and computing paradigm that consists of smart contracts to program and manipu...
