Blockchain-Based Decentralized Reputation Framework: Understanding the Residents’ Satisfaction About Living House with Trustworthiness Consideration

Learning the residents’ perspectives on living houses and their satisfaction feedback is meaningful for enterprise reputation service. Some channels (systems of surveys) have already been established in our daily life to help residents publish the residents’ satisfaction feedback. However, related satisfaction feedback data’s authenticity and integrity cannot be guaranteed in centralized architecture channels currently, which limits the authenticity of reputation judgment of related enterprises (e.g., the realtor company, the tenement company, and others) building organizations. To track the issues, a blockchain-based decentralized reputation framework is designed to ensure the tamper-proof and traceability of residence satisfaction feedback. The framework involves two parts: (1) building a residence satisfaction evaluation model; and (2) defining one type of smart contract to create an interactive and efficient feedback-sharing method in a decentralized blockchain architecture, which could effectively achieve the goals of transparency and trustworthiness. This study provides a novel solution for understanding the residence satisfaction with living houses with trustworthiness consideration, inspiring more discussions about blockchain technology.
