A consensus method for IoT blockchain based on timing mechanism

Abstract

The invention discloses a timing mechanism-based Internet of Things block chain consensus method, including steps: S1, the administrator node sets a minimum waiting period T After broadcasting the consensus start information, start the consensus cycle; S2, non-administrator nodes start the timer after receiving the broadcast information and set a random countdown Timer , T < Timer <2 T , send the confirmation message at the end of the countdown; S3. The administrator node sets the sender of the confirmation message received first as the backup node that generates the block, and analyzes the frequency of the block generated by the backup node before, if the frequency is within the preset range , the broadcast information authorizes this node to generate a new block; S4, the preparation node receives the authorization information to generate a new block, and ends the consensus cycle. The present invention can realize the application of blockchain technology in the Internet of Things with weak computing and storage capabilities, can realize the application of high-throughput blockchain, and can also make up for the defects of previous blockchain applications that consume a lot of computing, storage, and bandwidth.

Description

technical field [0001] The invention belongs to the key technical field of block chains, and in particular relates to a consensus method for block chains of the Internet of Things based on a timing mechanism. Background technique [0002] At present, in the field of Internet of Things, the system built by applying blockchain technology is still in the development period. The current research mainly focuses on the theoretical level, including the following aspects: identity authentication system, supply chain traceability, small transactions, data storage management Wait. However, how to achieve consensus among untrusted nodes in different application scenarios in the blockchain has been an important issue for a long time. As early as 1980, this problem was described as the Byzantine generals problem: there is a team of generals who want to capture a city, but in this army, some soldiers intend to attack, and the other part intends to retreat. How to reach a consensus in thi...

Problems solved by technology

[0003] The present invention aims at the problem that the existing block chain consensus method is not applicable to the Internet of Things system, and provides a block chain consensus method of the Internet of Things based on a timing mechanism. Randomly select and only select one node from the administrator node to obtain the right to generate blocks
