Embodiment 1

[0049] Such as figure 1 As shown, Embodiment 1 of the present invention provides a lightweight blockchain system resistant to parallel attacks. The system consists of bookkeepers, supervisors and business servers. The three can communicate with each other. There is only one bookkeeper, and there can be several supervisors and business servers.

[0050] Bookkeeper, used to generate and publish new business blocks according to the business data sent by the business server;

[0051] The supervisor is used to verify the correctness of the newly released business block, accept the block and update the current state of the block chain after the verification is passed; it is also used to supervise the state of the entire block chain;

[0052] The business server is used to send the business data that needs to be uploaded to the bookkeeper, and is also used to interact with the supervisor to confirm whether the blockchain is in a normal state.

[0053] Each part is described in de...

Abstract

The invention discloses a lightweight block chain system resistant to parallel attacks. The system includes a bookkeeper, a supervisor and a business server; wherein the bookkeeper is used to generate and publish business data sent by the business server New business block; the supervisor is used to verify the correctness of the newly released business block, accept the block and update the current state of the block chain after the verification is passed; it is also used to verify the state of the entire block chain Supervise; the business server is used to send the business data that needs to be uploaded to the bookkeeper, and is also used to interact with the supervisor to confirm whether the blockchain is in a normal state. The present invention implements a lightweight and low-cost blockchain through a new architecture design of "one bookkeeping and multiple supervision", and uses a unique consensus mechanism with anti-parallel computing capabilities, so that only a very small amount of calculation is required Resources and energy consumption can maintain the operation of the blockchain, which has the advantages of low cost and extremely fast deployment.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a lightweight block chain system resistant to parallel attacks. Background technique [0002] Blockchain (Blockchain) technology is a non-tamperable data storage technology. Blockchain technology packs the data to be stored into blocks, and then connects each block one by one through a digital summary algorithm to form a chain structure, which is called a blockchain. At the same time, the blockchain also needs to set a system consensus mechanism to ensure that the blockchain cannot be tampered with. [0003] The traditional blockchain technology adopts a distributed accounting model, which has many disadvantages such as large consumption of computing resources, complex consensus mechanism, and high operating costs. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, and propose a lightweight block chain sys...
