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 present disclosure provides a method and device for preventing blockchain forks. The method includes: selecting s consecutive blocks B n to B n+s ; created by block B n Node A n Generate for block B n key pair; node A n Continuously generate block B in the blockchain n+1 to B n+s remain active during the process until block B in consecutive s blocks n+s Become an immutable block; in response to block B in consecutive s blocks n+s Become an immutable block, use the private key PK' n for block B n+s Signing; Response to block chain subsequent generation of block B m , put the signature in block B m in; by creating s blocks B n to B n+s The nodes of each block in the block perform the above steps, thereby forming multiple backward links related to the block size of the blockchain; the newly added nodes used to create new blocks judge the area according to the number of backward links Whether the block chain is forked.

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...
