Data processing method for Internet of Things based on blockchain, Internet of Things and storage medium

Abstract

The invention discloses a data processing method for the Internet of Things based on a block chain, and the method comprises the steps that a first consensus node generates a data block according to terminal information data when the terminal information data is received, and stores the data block on the data block chain; and when the user transaction data is received, the second consensus node generates a transaction block according to the user transaction data, and stores the transaction block on the transaction block chain. The invention further discloses an internet of things based on theblock chain and a storage medium. According to the invention, the terminal information data in the Internet of Things is stored in the data block chain based on the workload consensus mechanism; usertransaction data is stored in a transaction block chain based on a practical Byzantine fault-tolerant algorithm; a hybrid consensus mechanism is adopted in the Internet of Things, the advantage of high decentralization degree of a workload consensus mechanism and the advantage of high consensus efficiency of a Byzantine fault-tolerant algorithm can be effectively combined, and the consensus security level and consensus efficiency of the Internet of Things based on the blockchain are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a data processing method of the Internet of Things based on blockchain, the Internet of Things and a computer-readable storage medium. Background technique [0002] Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods. Each data block contains A batch of bitcoin network transaction information is used to verify the validity of the information (anti-counterfeiting) and generate the next block. [0003] The combination of blockchain technology and the Internet of Things mainly solves the storage security problem of the Internet of Things data and the trust problem when transmitting data between devices. The transaction accounting of data transmission is completed by multiple nodes distributed in d...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a data processing method for the Internet of Things based on the block chain, the Internet of Things and a computer-readable storage medium, by dividing the data in the Internet of Things into two types: sensor data and user transaction data, respectively. A large amount of sensor data is stored on the blockchain using the POW consensus mechanism, and user transaction data with a relatively small amount of data is stored on the blockchain using the PBFT consensus mechanism, which combines the high security of the POW consensus mechanism and the PBFT consensus The advantage of high efficiency solves the technical problem of low consensus efficiency of the blockchain-based Internet of Things in the existing technology using a single proof-of-work mechanism
