　　隨著物聯網以及工業4.0的蓬勃發展，物聯網終端設備的數量將不斷創新高。在這樣的環境下所帶來的問題，將是中央伺服器因物聯網設備的增加，所造成的穩定性以及用戶的資訊安全威脅，因此我們將迫切需要一個完善且穩定的系統。
　　本研究提出了一個區塊鏈與物聯網結合的系統安全模型解決方案，運用區塊鏈技術取代原本物聯網的中央伺服器系統。區塊鏈網路將做為物聯網的底層運作系統。建構四層智能合約交互合作，分別處理系統的更新、註冊、數據儲存、授權等服務。並且開發讓用戶容易操作的使用者面界，方便使用者對物聯網設備的各項控制與儲存數據的即時掌握。
　　這個系統將會因區塊鏈散佈於各地的分散式節點，以及區塊鏈的容錯技術，而提高物聯網運作的穩定性。同時在區塊鏈加密技術的保護下，提升物聯網用戶資訊的安全性。藉由這套獨特且創新的區塊鏈物聯網系統，讓未來持續複雜與龐大的物聯網設備，有一個良好的底層基礎設施做為其發展的基石。

With the boom of the Internet of Things (IoT) and Industry 4.0, the number of IoT devices will continue to hit a record high. Due to the prosperous development of the IoT, the challenges of both the stability of the central server and the security of the user information are keeping on increasing. Under these circumstances, a stable and secure IoT system is urgently needed. This study proposes a system stability and security solution with the integration of blockchain, smart contract, and IoT technologies in order to replace the original central server system. The developed blockchain network serves as the underlying of operating system for the IoT. There are four interacting layers of the blockchain IoT smart contracts, which include system update, registration, data storage, and authorization layers. An ideal and user-friendly interface of immediate system control and data access for users is also proposed. Owing to the decentralized and distributed node characteristics of the blockchain, in conjunction with and fault-tolerant techniques, the stability and security of the IoT system are improved significantly. Moreover, the security of IoT user information is enhanced on account of the protection of the blockchain encryption technology. The novel intelligent blockchain IoT system can meet the strict requirements of the stability and security for increasing IoT system volume and complexity in the future.
