Blockchain-based Incentive System for Public Trash Bin

Public trash bins have problems with lack of security and incentive design. In Japan, only a few number of bins can be found because of those reasons. In order to solve this problem, a strong security-featured incentive system is required. This research aims at encouraging more people to provide public trash bins by offering the benefit such as privacy, security and incentive scheme. We propose a blockchain-based incentive system which consists of a smart trash bin, a smartwatch as a wearable payment device, and an incentive scheme using ethereum smart contract.
