Problems solved by technology

[0004] Since one of the original intentions of the invention of the blockchain is to ensure that the chain cannot be tampered with, the existing blockchains are faced with a problem: if illegal or inappropriate data enters the chain for storage, then the illegal or inappropriate data cannot be clear from the chain
[0007] The existing data update scheme in the blockchain needs to back up the data in the entire blockchain and reorganize the blockchain to exclude illegal or inappropriate data in the blockchain, which brings great The amount of calculations cannot efficiently eliminate illegal or inappropriate data in the blockchain

Abstract

The invention discloses a method and device for updating data in a block chain and equipment. The method comprises the following steps that: acquiring information to be stored in the block and internal data of a block head block, and according to the information to be stored in the obtained block and the internal data of the block head block, calculating an association value of a previous block, combining the information to be stored in the obtained block, the internal data of the block head block, the random value of the block and the calculated association value of the previous block into anew block, and replacing the original block with the combined new block. By means of the mode, illegal data or unsuitable data in the block chain can be efficiently eliminated.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, device and equipment for updating data in block chains. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm, which can be applied in many fields. The core advantage of blockchain technology is decentralization. By using data encryption, time stamps, distributed consensus and economic incentives, it can realize point-to-point transactions and coordination based on decentralization in a distributed system where nodes do not need to trust each other. It provides a solution to solve the common problems of high cost, low efficiency and insecure data storage in centralized institutions. [0003] See figure 1 , figure 1 It is a schematic diagram of an example of the chain structure of the existing blockchain. Such ...
