Design And Implementation Of Anti-tampering Subsystem Of Geological Exploration Big Data Based On Blockchain

Blockchain technology,as an emerging frontier technology in the information age,has attracted extensive attention of the government and the community in recent years,which has achieved remarkable application results in many industries.Geological exploration is a data-intensive work.To further gather and share industry geological exploration data and strengthen the management of data assets in the geological exploration industry is the top priority of the current geological exploration work.This paper combines the blockchain technology with the supervision of geological exploration projects,designes and implementes an anti-tampering subsystem of geological exploration big data based on blockchain by studying the key technologies such as smart contract,blockchain data structure,etc.The system can upload some core data collected during the supervision of geological survey projects to the blockchain by executing smart contracts,and use the consensus mechanism of the blockchain to verify its consensus,which can not only solve the problem of anti-tampering of geological survey big data to a certain extent,but also help to realize the sharing of geological survey data among industries in the future,thereby further promoting the development of the geological survey industry.The research work of this paper is supported by an application platform,a smart geological survey supervision platform,in the field of geological survey project supervision.Therefore,this paper first introduces the business process of the supervision work in geological exploration projects,sorts out the business data collected by the smart supervision platform and extracts the data types that require data tamper-proofing for geological surveys through deep analysis and mining.According to this,this paper proposes the whole architecture of the anti-tampering subsystem of geological exploration big data.Subsequently,based on the underlying development platform of the FISCO BCOS blockchain,this paper builds a blockchain network,carries out detailed design and development of the various functional modules of the geological prospecting big data anti-tampering subsystem.Finally,this paper tests the geological prospecting big data anti-tampering subsystem.The test results show that the geological prospecting big data anti-tampering subsystem designed and implemented in this paper satisfies the need for anti-tampering of geological survey big data with less computational and communication costs,which provides a fast,safe,and reliable data tamper-proof service for geological survey supervision work,and offer a valuable reference for the application of blockchain technology to other industries.
