Embodiment 1

[0030] Such as figure 1 As shown, the block chain-based drawing access device includes: several storage nodes and several use nodes, and the first block chain network interconnecting all storage nodes, and the second block chain network interconnecting all use nodes network; the storage node is used to divide the complete drawing information and store the divided sub-drawing information; the use node is used to read the sub-drawing information in the storage node and use the read sub-drawing information; it is characterized in that the information ratio range of the sub-drawing information that can be read by any one of the using nodes and the complete drawing information is: 1% to 99%; the first block chain network and the second block The communication connection between the chain network; after the complete drawing information is divided, the method for storing the divided sub-drawing information performs the following steps: input the complete drawing information; obtain t...

Embodiment 2

[0033] On the basis of the previous embodiment, the method of calculating the individual energy in the cluster population according to the updated membership degree, and then obtaining the cluster label performs the following steps: use the following formula to calculate the individual energy in the population: Among them, ζ is an adjustment constant, and its value ranges from 20 to 50; according to the obtained individual energy value, the individuals in the clustering population are divided into three categories on average, and different clustering labels are set for the three types of individuals.

[0034] Using the above technical solution, the process of dividing a collection of physical or abstract objects into multiple classes composed of similar objects is called clustering. A cluster generated by clustering is a collection of data objects that are similar to objects in the same cluster and different from objects in other clusters. "Birds of a feather flock together...

Embodiment 3

[0037] On the basis of the previous embodiment, the method of dividing the individuals in the cluster population into three categories on average performs the following steps: use the following formula to divide the individuals into three categories on average according to the energy of the individuals in the middle group:

Abstract

The invention belongs to the technical field of blockchains, and particularly relates to a blockchain-based drawing access device and method, and a storage medium, the blockchain-based drawing accessdevice comprises a plurality of storage nodes, a plurality of use nodes, a first blockchain network for interconnecting all the storage nodes, and a second blockchain network for interconnecting all the use nodes; the storage node is used for segmenting the complete drawing information and then storing the segmented sub-drawing information; the use node is used for reading the sub-drawing information in the storage node and using the read sub-drawing information; and the device hasthe advantages of high safety and high operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a drawing access device, method and storage medium based on blockchain. Background technique [0002] The blockchain originated from Bitcoin. On November 1, 2008, a person who claimed to be Satoshi Nakamoto (Satoshi Nakamoto) published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", explaining that based on P2P network technology, encryption The architectural concept of the electronic cash system, such as time stamp technology, blockchain technology, etc., marks the birth of Bitcoin. Two months later, the theory entered practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, on January 9, 2009, a block with serial number 1 appeared, and was connected with the genesis block with serial number 0 to form a chain, marking the birth of the blockchain. [0003] In recent years, the world's attitude toward...
