Embodiment 1

[0066] Such as figure 1 As shown, the present invention provides a personal file permission chain management system based on improved multi-layer PBFT, including a sequentially connected node management module, a hierarchical division module, and a consensus module; the node management module is used to utilize the personal file permission chain to participate in Node creation, level assignment, and node deletion management are performed on the nodes respectively; the level division module is used to divide all nodes into levels according to their levels, and perform custom hierarchical processing through the node level and subordinate node ID list; the consensus module, It is used to optimize the combination of PBFT consensus algorithm, multi-layer nodes and incentive mechanism, and complete the management of personal file permission chain based on improved multi-layer PBFT.

[0067] In this embodiment, the present invention divides the system into three stages: the node mana...

Embodiment 2

[0069] Such as figure 2 As shown, the present invention also provides a personal file permission chain management method based on improved multi-layer PBFT, including node management stage, hierarchical division stage and consensus process stage;

[0070] The node management phase includes the following steps:

[0071] A1. Use the personal file permission chain to register the accounts of employees in various positions, and create nodes for employees to join the network;

[0072] A2. Assign the grades of the created nodes according to the positions of the employees, and the implementation method is as follows:

[0073] A201, the newly added node defaults to the lowest level;

[0074] A202. Allocate nodes according to employee positions, and broadcast proposals for the assigned high level;

[0075] A203. Determine whether more than two-thirds of the consent messages have been received, if so, assign the required grade, and set the highest grade as T0 grade, and enter step A...

Abstract

The invention provides a personal file permission chain management system and method based on improved multi-layer PBFT, belongs to the technical field of block chains, and comprises a node managementmodule, a hierarchical division module and a consensus module which are connected in sequence. The node management module is used for performing node creation, grade allocation and node deletion management on participated nodes by utilizing a personal file permission chain; the hierarchical division module is used for carrying out hierarchical division on all the nodes according to the levels ofthe nodes and carrying out user-defined hierarchical processing through the node levels and the slave node ID list; and the consensus module is used for realizing optimization in combination with a PBFT consensus algorithm, the multi-layer nodes and an excitation mechanism. Through the design, the problems that a license chain system is poor in node expansibility, high in inter-node communicationcomplexity, low in system efficiency after the number of nodes is increased and the like are solved, the total single consensus communication duration of the license chain management system is effectively shortened, and the single consensus communication frequency is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a personal file permission chain management system and method based on improved multi-layer PBFT. Background technique [0002] As the underlying technology of Bitcoin, blockchain has gradually appeared in the public eye. Since then, blockchain technology has entered the era of 1.0 digital currency, and the real application of blockchain technology to scenarios other than digital currency is due to Ethereum. Ethereum has brought blockchain technology into the 2.0 era of smart contracts, and it is currently developing rapidly. Whether it is Bitcoin or Ethereum, or any other blockchain application, it should be supported by four major technologies: cryptography, distributed technology, smart contract and consensus algorithm. The consensus algorithm is responsible for the consensus between nodes in the blockchain. Consensus verification of block data, while the cor...
