An Anonymity and Interaction Supported Complaint Platform based on Blockchain Technology for National and Social Welfare

People face numerous severe problems in their everyday life. Extortion, corruption, threat, harassment, negligence, poor public service, etc., are some common problems people are dealing with everyday. As it may take a long time, most of the victims do not have the intention to complain anymore. As a result, these issues are getting worse rather than getting resolved. There are some ways online to contact and complain to the competent authorities. However, a complainant may be hesitant to complain in fear of insecurity because of the transparency issue of a centralized system. To resolve the issues, in this paper, we will present a blockchain-based anonymous, transparent, and decentralized platform, where people can complain anonymously and interact with the authorities to resolve their complaints. An authority can start resolving a complaint after receiving it from the platform. Those facing a similar problem or evaluating a problem to be prioritized can support/oppose the complaint. Complaints like damaged roads or pandemic situations like Covid-19 may need some financial support to be solved. In this case, authorities can start crowdfunding where both complainants and authorities can donate. Ultimately, we can claim that our proposed blockchain-based platform will be one of the most secure and reliable platforms for complainants to complain about their issues.
