Blockchain-based Rental Documentation Management with Audit Support

In the rental market, document management is a critical process to ensure the accuracy of financial transactions and regulatory compliance. In Portugal and many other countries, challenges include the complexity of legislation, particularly GDPR compliance, lack of transparency, and bureaucratic inefficiencies. With this in mind, a solution based on Hyperledger Fabric, a blockchain platform, is presented for the implementation of a document management system for the rental process that supports auditing. This system oversees the rental process. We present the system, a prototype, and an experimental evaluation.
