Blockchain-Based Network Concept Model for Reliable and Accessible Fine Dust Management System at Construction Sites

Abstract

In total, 44.3% of particle matter 10 (PM10) is fugitive dust, and one of the main sources of fugitive dust generation in Korea is construction work (22%). Construction sites account for 84% of the total business places that have reported fugitive dust generation. Currently, the concentration of fine dust at construction sites is being remotely monitored by government inspection agencies through IoT sensors, but it is difficult to trust that appropriate fine dust reduction measures are being taken, because contractors can avoid taking these measures by submitting false reports or photos. In addition, since the fine dust monitoring system under government management is not an open platform and centralized system, residents near construction sites encounter difficulties in accessing information about fine dust. Therefore, in this study, we designed and constructed a blockchain network model to transparently and reliably provide network participants with the information associated with IoT data and fine dust reduction measures. To operate the blockchain network, we designed the chaincode, DApp, and network architecture. In addition, information on fine dust concentration and reduction measure photos were shared with the participants via the blockchain search tool (Hyperledger Explorer). The proposed blockchain network is expected to form a trust protocol among contractors, government inspection agencies, and citizens.

Retracted: The use of the intelligent Bayesian network method combined with blockchain technology in the optimisation of tunnel construction quality control

“…The model established by combining the Internet of Things and blockchain technology can realise remote monitoring of construction sites. The authenticity of monitoring is achieved through the fundamental prevention of data forgery and information sharing of distributed ledger technology and decentralisation [5]. Taking the blockchain network as an example to conduct visualisation can verify the feasibility of blockchainbased construction quality information management.…”

Unlocking Blockchain in Construction: A Systematic Review of Applications and Barriers

“…Cho et al [114] used a blockchain network to manage air quality at a construction site using a fine dust management system by designing a chaincode, dApp, and network architecture. Also, blockchain has been used for environmental monitoring and control of carbon emissions [59] and other pollutants [115] in the construction field.…”

Analysing the alignment between circular economy and industry 4.0 nexus with industry 5.0 era: An integrative systematic literature review

“…Blockchain technology is a secured digital ledger that generates and tracks data (Cho et al, 2021). It comes in various forms depending on the individual's objective, but the outcome extracted is instantaneous Furthermore, it can be noted that resilience has yet to be analysed with a circular paradigm.…”
