Problems solved by technology

[0015] In view of some loopholes in the public chain protocol POW existing in the existing technology (that is, the mining model is not perfect), the defects of the search method in the process of generating and maintaining the blockchain, and the network communication in the real world cannot fully support the public chain. Due to the actual situation of blockchain applications, it is necessary to propose a new basic architecture of blockchain, that is, not to base security on searching from the head upwards, thereby reducing the risk of forks

Abstract

The invention provides a method and a device for preventing bifurcation of a block chain. The method comprises the following steps: selecting continuous s blocks Bn to Bn+s; generating, by the node Ancreating the block Bn, a key pair for the block Bn; enabling the node An to keep active in the process that the block chain continuously generates the blocks Bn+1 to Bn+s until the blocks Bn+s in thecontinuous s blocks become non-tampered blocks; in response to the fact that the block Bn+s in the continuous s blocks becomes a non-tamperable block, signing the block Bn+s by using a private key PK'n; responding to a subsequently generated block Bm of the block chain, and placing the signature in the block Bm; executing the above steps by the node for creating each of the s blocks Bn to Bn+s, thereby forming a plurality of backward links related to the block scale of the block chain; and judging whether the block chain is bifurcated or not by the newly added node for creating the new blockaccording to the number of the backward links.

Description

technical field [0001] The present disclosure generally relates to the technical field of block chains, and in particular relates to a method and device for preventing block chain forks. Background technique [0002] With the rapid development of blockchain technology, many innovations have been proposed in the design, mainly focusing on avoiding evil and consensus mechanisms. Avoiding evil is based on the principle of economic games. In an open network, technical means cannot be used to ensure that everyone is cooperative, but economic games can be used to benefit cooperators and make non-cooperators suffer losses and risks. For example, all participants in the Bitcoin network must first pay the cost of mining and consume computing power. The right to decide to get a new block is proportional to the mortgaged computing power. Once it fails, these computing power will be confiscated and become a sunk cost. When there are many participants in the network, the computing pow...
