隨著科技的演進，各國政府與企業正積極研發區塊鏈技術與尋找應用情境，推動經濟成長和提升企業效率，區塊鏈技術具有去中心化、無法片面竄改、透明公開交易等特性，利用區塊鏈密碼技術在各方和裝置間建立信任關係，並降低共謀和篡改的風險，消除中間人和仲介機構的相關開銷來降低成本，縮短運算時間從而加速交易。電信業在物聯網扮演網路層的角色，擁有可觀的企業與個人用戶量，在5G時代來臨之際，全面智慧化的物聯網情境將快速發展，各種大數據應用也愈來愈豐富，電信業朝物聯網服務的平台層和應用層發展方向，物聯網具有設備多元、資料量龐大等特性，結合區塊鏈應用模式，減少利潤剝削、有保障的信任機制、取回資料自主權，創造新商業模式。因此本研究利用區塊鏈去中心化技術為核心，提供具防竄改性的高安全與高信賴特性，結合電信業物聯網平台，透過網路將資料傳送到物聯網平台，進行不同資料各項數據分析與智慧服務運用，完成資料儲存技術與數位價值傳遞，建立信任、降低成本和加速交易之目的，提供政府與企業平台新應用服務。

The technology of blockchain and the application of blockchain are developing rapidly in many countries and enterprises, which promotes economic growth and improves productivity. The blockchain accelerates trading speed and shortens accounting time with the technology of coding to establish the trust in any devices, to reduce risk of conspiracy and tampering, and to cost down the spending of agency, with its character of decentralized, indelible ledger and transparency.As the coming of 5G (5th Generation Mobile Networks) and the rapid intellectual development of IoT, telecommunications will be toward to develop the service-platform and the application of IoT (Internet of Thing) and combine the application of blockchain to create a brand new business model by cost down, guaranteed trust, and the self-determination of data. Therefore, this study focus on the decentralized technology of blockchain, which is with its highly safe, reliable and tampering-resist character, to provide the new service and platform for government and enterprises by combining the IoT of telecommunication to transfer data in the platform of IoT, analyzing different data, application of intellectual service to reach the purpose of establishing trust, cost down and accelerating the trading speed.
