Problems solved by technology

Non-licensed chains often participate in the construction of blockchains by calculating a given hash value. This method not only wastes computing and power resources, but also greatly limits the speed of computing processing. The architecture often adopts a Byzantine fault-tolerant mechanism, which is greatly limited by the bandwidth throughput and cannot achieve effective expansion
Among them, the application of blockchain in the Internet of Things is particularly critical. The blockchain can ensure that communication devices in the Internet of Things can effectively interact and transmit information, preventing possible failures and attacks, but still faces communication efficiency. Bad, there is a lack of connection between various blockchains, or the pressure load of a main chain is too large

Embodiment 1

[0070] Such as figure 1 As shown, the multi-layer blockchain protocol expansion system based on the communication equipment system includes the root chain, several side chains built on the root chain in a tree structure, and communication devices connected to the root chain and the side chain respectively; the side chain It is connected to the root chain through smart contracts, and the side chain regularly submits block headers generated within a fixed time to its parent chain. The side chain is used to use the interactive application of the smart contract to join the root chain, and use the node to run the consensus protocol to submit the generated block header to the parent chain node; the communication device is used to register and run on the side chain, Transfer the communication equipment information on the root chain to the side chain; and send an exit request to return to the root chain; the root chain is used to add the side chain to the root chain through the intera...

Embodiment 2

[0073] Such as figure 2 As shown, based on the communication equipment system-oriented multi-layer blockchain protocol expansion method, the implementation method is as follows:

[0074] S1. The side chain uses the application to join the root chain. The implementation method is as follows:

[0075] S101. Using the IoT master node of the side chain to send registration information requesting to join to the root chain;

[0076] S102. According to the request information, use the block header hash value of the generated first block as the block chain address of the side chain, and use the address of the side chain and the upper-level block that manages the side chain The parent side chain address of the chain is also sent to the side chain;

[0077] S103. Broadcast identity information to the parent side chain through all nodes of the side chain;

[0078] S104. Record the registration information of the side chain to the state tree of the parent side chain, exclude illegal s...

Abstract

The invention provides a multi-layer blockchain protocol expansion system and method based on a communication-device-oriented system, belongs to the technical field of blockchains. The system comprises a root blockchain, a plurality of side blockchains constructed on the root blockchain in a tree structure, and communication devices respectively connected with the root blockchain and the side blockchains. The invention aims to solve the problems that a blockchain expansion technology based on a trusted root blockchain is used for establishing a multi-layer blockchain expansion protocol oriented to the Internet of Things, and under the condition of ensuring the record security of communication equipment, the record change speed of the communication equipment on the root blockchain and the flexibility, autonomy and availability of the record change of the communication equipment are greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a multi-layer block chain protocol expansion system and method based on a communication equipment system. Background technique [0002] With the breakthrough and development of blockchain technology, people's demand for building a complete ecology on the basis of blockchain is becoming stronger and stronger. The blockchain has the characteristics of decentralization, non-tampering, and non-forgery. It is especially suitable for building trust models used in various industries in various dimensions, and has important social practical significance and value. Because the current blockchain architecture is mainly faced with the limitations of consensus and credibility, and the impossible triangle, that is, the problem that security, scalability, and decentralization cannot be achieved at the same time. Non-licensed chains often participate in the construction of blo...
