Blockchain fragment enabling knowledge graph file storage method

Abstract

The invention relates to a blockchain fragment enabling knowledge graph file storage method, and belongs to the technical field of blockchain application. According to the method, the knowledge graph file is stored in the blockchain, so that the problems of safe storage and traceability of the knowledge graph construction file are solved. When a reasoning error or a file security problem occurs in the knowledge graph, the corresponding process file can be obtained from the blockchain according to a demand, and a repetitive construction process can be avoided. The method is based on an inter-fragment communication confirmation mechanism, and double-pattern attacks aiming at different fragments are prevented. Through a random verification function, asset mortgage and an improved practical Byzantine fault-tolerant mechanism, malicious behaviors of nodes are prevented, and transaction security in fragments is ensured. According to the method, the throughput of a blockchain system is improved by adopting an optimized fragmentation scheme, and under multiple constraint conditions, an optimal transaction selection scheme is given based on a dynamic programming algorithm to maximize the income of the fragmentation, so that efficient and reasonable transaction fragmentation is realized.

Description

technical field [0001] The invention relates to a method for storing knowledge map files empowered by block chain sharding, and belongs to the technical field of block chain applications. Background technique [0002] With the vigorous development of artificial intelligence, knowledge graph has received extensive attention. In the process of knowledge graph construction, process files are easily tampered and forged maliciously, resulting in deviations in reasoning results. Blockchain has the characteristics of transparency, tamper-proof, traceability, etc., and has broad prospects in the process of building knowledge graphs. When reasoning errors or file security issues occur, the corresponding process files can be obtained from the blockchain according to requirements, avoiding repetitive work such as knowledge map reconstruction. [0003] Scalability is a key factor that hinders the further widespread application of the blockchain system. Its core is to solve the two asp...

Problems solved by technology

In the account / balance model, transactions are usually sharded to a shard based on the sender address. Using this method, double-spend transactions can be easily detected without cross-shard communication, but distributed rejection cannot be prevented. service attack

When an attacker uses the same address to initiate a large number of transactions, these transactions will be assigned to the same shard, causing the resources of the shard to be exhausted rapidly
