Internet of Things data expansion storage method and system based on block chain, and computing device

Abstract

The invention discloses an Internet of Things data expansion storage method and system based on a block chain and a computing device, and the method comprises the steps: an environment deployment step: deploying a block chain operation environment at an edge gateway and a server, and building a block chain network by taking the edge gateway and the server as block chain nodes; a request monitoring step: respectively monitoring a device monitoring data storage request sent to the block chain by a user through an interface of a server or an edge gateway by a device detection data storage smart contract in the block chain, enabling an equipment maintenance data storage smart contract in the block chain to monitor an equipment maintenance data storage request sent by a user to the block chain through an interface of a server or an edge gateway; and a data storage step: when the corresponding data storage request is monitored, storing the data in the data storage request into the corresponding fragment according to the block chain fragment capacity expansion storage method. Expansion storage of the block chain is realized through a fragmentation technology, the storage capacity of the block chain is improved, and the storage capacity problem faced by the block chain is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to the field of block chain technology, and in particular to a method, system, and computing device for expanding and storing Internet of Things data based on block chain. Background technique [0002] Blockchain is a new application model that integrates distributed storage, point-to-point transmission, consensus mechanism, encryption algorithm and other existing technologies. It has the characteristics of decentralization, tamper-proof, traceability, openness and transparency, etc. been widely used in. Domestic and foreign researchers have done a lot of research on the application of blockchain in the Internet of Buildings, realizing safe and reliable storage and access control of Internet of Buildings data. [0003] With the rapid development of the Internet of Buildings technology, the number of smart devices and sensors in the Internet of Buildings is gradually incre...

Problems solved by technology

The way to expand the disk is to estimate the disk usage capacity, suspend the blockchain service when the estimated disk usage capacity is about to be reached, and restart the blockchain service after replacing a larger-capacity disk to realize the storage expansion of the blockchain. The blockchain service will be suspended when the disk is deleted, so it will affect the normal use of users

The method of using an external database reduces the amount of data that the blockchain needs to store by transferring part of the data in the blockchain to an external database to achieve storage expansion. However, this method requires an additional external database, which increases storage costs and storage capacity. the complexity

[0005] For the problem of insufficient storage capacity in the prior art, no effective solution has been proposed
