A smart waste management system using IoT and blockchain technology

摘要

Blockchain technology and Internet of Things are two of the most popular technologies today. IoT is an interconnection of devices that has the capability to sense, measure, process the state of environmental indicators as well as themselves and actuate based on the input provided. It can help create smart solutions that can enhance the quality of life of people. Likewise, blockchain is distributed database systems that promise high level of security and availability of data with least transaction overhead. In this thesis, we attempt to bring together these two technologies to develop a Smart Waste Management System (SWMS). The SWMS is weight-based i.e. users have to pay for use of services as per the amount of waste they produce. Payments are made using a custom cryptocurrency regulated by Smart Contracts and the entire SWMS can be funded by a DAO through a totally automate, highly secure process. Blockchain can help lower the penetration and service cost which can be specially beneficial to developing countrieswhere governments are not very resourceful. This thesis attempts to establish a proof of concept through measurement of performance and assessment of applicability of such a system.
