A Framework of Blockchain Technology in Intelligent Water Management

Abstract

At present, water resource information management in China is mainly a centralized model, and there exist some problems such as high cost, low efficiency, and data storage insecurity. Blockchain technology provides a good solution which can create an efficient trust mechanism among the links in the process of water resource utilization. It guarantees the security of the data, avoiding the sudden collapse of the central institutions caused by some normal operations of the entire system. Based on a decentralization blockchain, we propose a decentralized water resource information management system for the whole process of “supply-use-consumption-discharge,” which improves the traditional water data storage. Specifically, the monitoring and business data are encrypted by the blockchain and are transmitted using a peer-to-peer network. Moreover, the centralized management mode is changed and part of the management work is dispersed to each node. Thus, decisions and measures can be made and implemented quickly after discovering problems to improve the efficiency of information transmission and management. In addition, two typical blockchain-based application scenarios for water resource management are designed. A blockchain-based approach makes issuing and monitoring water abstraction permits more convenient and obtaining license information more secure and verifiable. A reliable mechanism for tracing water quality ensures the accuracy and reliability of water quality information, enables the detection of locations with inadequate water quality, and clarifies people’s responsibility, thus guaranteeing the water safety of the residents.

Blockchain Opportunities for Water Resources Management: A Comprehensive Review

“…According to Ragghianti [44], blockchain allows for the integration of watershed monitoring and direct management of water usage for all system users, maintaining flexibility and guaranteeing all socio-environmental constraints that apply in that basin. Xia et al [45] consider a distributed and decentralized water data management system for the whole supply, consumption, and discharge processes. The system includes two conceptual hybrid blockchain-based solution scenarios: permits for water abstraction and water quality tracking.…”

Artificial intelligence and machine learning for the optimization of pharmaceutical wastewater treatment systems: a review

“…The convergence of blockchain technology, internet of things, artificial intelligence, and machine learning algorithms into cyber-security systems synergistically enhances trust, transparency, privacy, and cyber-security of overall operational systems in pharmaceutical wastewater treatment systems by providing a shared and decentralized distributed ledger (Xia et al 2022). A blockchain technology, generally known as a distributed ledger, can store all information or data related to industry assets like a register (Thakur 2022).…”
