AI总结：
针对葡萄牙租赁市场文档管理的合规与透明度问题，提出基于Hyperledger Fabric的区块链文档管理系统，通过智能合约记录元数据并协调访问，实现不可篡改、可追溯的租赁全流程记录与审计支持。
摘要：
租赁市场的文档管理是确保该领域金融交易准确性和监管合规性的关键过程。在葡萄牙，面临的挑战包括立法的复杂性，特别是 GDPR 不合规、缺乏透明度以及官僚流程效率低下。考虑到这一点，提出了一种基于区块链平台 Hyperledger Fabric 的解决方案，用于实施租赁流程的文档管理系统。该系统监督租赁流程，该流程包括三个阶段：准租客通过上传必要文件申请房产、房东对收到的各种申请进行接受/拒绝，以及系统创建报告，该报告只有审计员才能请求和查看。系统智能合约记录与文档相关的元数据（哈希、所有者），并协调房东向准租客提出的文件访问请求。因此，系统负责为整个流程创建不可篡改且可追溯的记录。底层平台作为进行未来审计的基础。在房东验证文件并接受租赁提案后，任何经授权的审计员都可以通过访问最终报告中的记录来请求房产报告，该报告包含流程中发生的所有事件。
英文摘要：
Document management in the rental market is a critical process to ensure the accuracy of financial transactions and regulatory compliance in the sector. In Portugal, the challenges include the complexity of legislation, particularly GDPR non-compliance, lack of transparency, and bureaucratic process inefficiency. 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. This system oversees the rental process, which consists of three phases: the application for a property by the prospective tenant through the upload of necessary documents, acceptance/rejection by the landlord of various received applications, and the creation of a report by the system, which only the auditor can request and view. The system smart contract records metadata associated with the documents (hash, owner) and coordinates requests for file access by landlords to prospective tenants. Thus, the system is responsible for creating immutable and traceable records of the entire process. The underlying platform serves as the foundation for conducting future audits. After the landlord verifies the files and accepts the rental proposal, any authorised auditor can request a report for a property by accessing the records through the final report, which includes all events that occurred during the process.
