Embodiment

[0030] The core feature of the new blockchain system is that it adopts the quantum Byzantine consensus protocol, and its flow chart is as follows: figure 2 As shown, it mainly includes the following steps:

[0031] Step 1: Master node P in the user layer 1 selection. In this embodiment, each node adopts a rotation system to determine the master node P of each round of consensus 1 . master node P 1 Transmit the quantum state with other ordinary nodes through the quantum channel to cooperate to complete the quantum phase estimation algorithm, thereby generating a set of secret number lists l with specific associations; each consensus on the complete block needs to first select the master node P 1 .

[0032] Step 2: Master node P 1Distribute 256 sets of secret lists l with specific associations with other ordinary nodes through quantum computing and quantum channels.

[0033] In this embodiment, each node needs to generate a corresponding set of secret number lists throug...

Abstract

The invention discloses a novel block chain system based on a quantum Byzantine consensus protocol, and belongs to the field of quantum information calculation and block chain distributed consensus protocols. The system architecture comprises a user layer, a core layer and a base layer. The user layer comprises node management and service functions; the core layer comprises a quantum Byzantine consensus protocol, a smart contract and an encryption algorithm; the base layer includes a computing storage and a peer-to-peer network. Different from other block chain systems, a peer-to-peer network in a base layer of the novel block chain system adopts a classical channel and a quantum channel to realize inter-node communication. The classic channel is used for transmitting a large amount of classic block data; a quantum channel is combined with a quantum computing technology to realize a novel secret digital list distribution mode, and the secret digital list distribution efficiency and the quantum resource utilization rate are improved. And each node in the user layer achieves the quantum Byzantine consensus protocol in the core layer through the secret digital list, so that the fault-tolerant capability and the security of the block chain system are improved.

Description

technical field [0001] The present invention relates to the field of quantum information and computing and the field of block chain distributed consensus protocol, and specifically designs a new type of block chain system based on quantum Byzantine consensus protocol. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Its innovative distributed de-intermediation trust system has changed the traditional Internet relying on centralized institutions to establish and maintain trust systems. It has changed the mechanism of traditional Internet relying on central institutions to establish and maintain trust. have a profound impact. From a technical point of view, the blockchain can be regarded as a distributed ledger for data storage in a distributed system. The consensus mechanism ensures how to maintain data consistency when dis...
