Problems solved by technology

In this way, if the currency holding weight in a blockchain node account exceeds 51%, this blockchain node has a certain opportunity to obtain the packaging right of the next block, which will discourage the mining enthusiasm of other blockchain nodes , and will bring risks to the entire blockchain system

Abstract

The invention discloses a method for effectively preventing 51% attack in a real-name block chain PoS mechanism, a block chain system and a computer readable storage medium. According to the method, the packaging difficulty of accounts is adjusted through a preset modulation factor function and the cash weight of the accounts, wherein the modulation factor function is used for describing the relationship between the cash weight of the accounts and the modulation factors of the probability of an account packaging block, and the modulation factor function is configured to enable the modulation factor of the probability when the cash weight of the accounts is Default to be maximum, and Default is greater than 0 and smaller than 50%. The block chain system solves the problem of 51% attack, andthe efficiency of the block chain system is improved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of blockchain technology, and more specifically to a method for effectively preventing 51% attacks under a real-name blockchain PoS mechanism, a blockchain system, and a computer-readable storage medium. Background technique [0002] Blockchain is a new application technology collection of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. From a data point of view, the blockchain is a chained data structure that combines data blocks in a sequentially connected manner in chronological order, and the data structure is cryptographically guaranteed to be tamper-proof and unforgeable. From a technical point of view, blockchain technology integrates a variety of different technologies. By building a blockchain network, each blockchain node in the network is allowed to obtain a complete ...
