目前建築生命週期中的建管履歷書件管理方式主要是依賴肉眼比對，這種方式耗時費力且效率不佳。更甚的是，細微的竄改很難在第一時間被發現，導致出現建管上的四大問題：「建築履歷書件安全問題」、「機關間傳遞建築履歷書件缺乏信任，致使效率低下」、「傳統的中心化驗證系統有真實性之疑慮」和「建築履歷書件欠缺公開透明」。存證雖然能夠驗證文件是否遭到竄改，然而在中心化機制下仍存在存證本身被竄改的可能性。因區塊鏈具去中心化、公開透明和防止竄改的特性，將存證技術與區塊鏈技術結合來解決建築履歷書件的現況問題是一個值得探討的問題。
然而，區塊鏈有三種類型，包括公有鏈、聯盟鏈和私有鏈。本研究參考文獻並制定指標，綜合評估這三種區塊鏈類型，以確定在不同的建管問題下，分別適用於哪種類型的區塊鏈。本研究最終選擇了相對適合的公有鏈作為基礎，設計了一個建築履歷書件管理機制的區塊鏈存證系統。該系統具備多檔上鏈機制，能夠將同一建照下的所有圖說一同上鏈存證。在驗證過程中，只需上傳一個或多個圖說，即可驗證其所屬的建照以及在區塊鏈上的狀態。這不僅能確保案件的完整性，還能提高上鏈效率並降低成本。

Currently, the management of construction-related documents in the building
lifecycle relies primarily on visual comparison, which is time-consuming and
inefficient. Moreover, subtle alterations are difficult to detect in a timely manner,
resulting in four major issues in construction management: "security issues with
architectural documents," "lack of trust in the transmission of architectural documents between agencies leading to low efficiency," "doubts about the authenticity of the traditional centralized verification system," and "lack of transparency in architectural document management." Although record-keeping can verify if a document has been tampered with, there is still a possibility of tampering within a centralized mechanism. Considering the decentralized, transparent, and tamper-resistant characteristics of blockchain, it is worth exploring the integration of record-keeping techniques with blockchain technology to address the current challenges in architectural document management.
However, there are three types of blockchain: public chain, consortium chain, and
private chain. This study references to existing literature and formulates criteria to comprehensively evaluate these three types, determining which type is most suitable for addressing various architectural management issues. Ultimately, this study selected the most appropriate public chain as the foundation and designed a blockchain-based evidence storage system for architectural document management. The system incorporates a multi-file uploading mechanism, enabling the simultaneous storage and verification of all drawings under the same building license on the blockchain. During the verification process, only one or multiple drawings need to be uploaded to verify their association with the building license and their status on the blockchain. This not only ensures the integrity of the case but also enhances the efficiency and reduces the cost of record-keeping.
