Abstract

The invention discloses a lot drawing method based on a random shuffling algorithm with a weight and application, the method comprises two parts of a lot drawing process and a verification process, a shuffling method is provided for determining a block chain block discharger sequence, if a consensus node cannot be discharged from a block, the block is discharged from a second node, and so on; in addition, a random shuffling function with a weight is adopted, and it can be guaranteed that the output priority sequence probability is in direct proportion to held rights and interests. The lot drawing method can be used for leader node election and committee node election. According to the method, block-out consensus in the asynchronous network can be realized, multiple rounds of consensus are not needed, the requirement on network synchronization is greatly reduced, the Sybil attack can be resisted, and the security is greatly improved.

Description

technical field [0001] The invention relates to a lottery method, in particular to a lottery method based on a weighted random shuffling algorithm and its application. Background technique [0002] Blockchain is another Internet revolution after big data and artificial intelligence, which integrates multiple technologies such as distributed computing, encryption technology and provable security. Blockchain technology provides a viable solution for decentralized systems. A core step in the blockchain is consensus, that is, how to decide which miner's block is received on the chain when multiple miners generate blocks. [0003] Bitcoin is the first widely used blockchain system, using the PoW consensus mechanism. In the PoW consensus mechanism, computing power is the decisive factor for block generation, that is, the fastest computing node, its block is easier to be uploaded and rewarded. Under this system, since only one block produced by one node can be accepted into the ...
