Abstract: | 區塊鏈技術的發展為不但讓我們看到了比特幣這種虛擬貨幣發展的盛況,也為資訊界帶來了很大的啟發,紛紛積極探討未來可能的變化及嘗試各式各樣的應用。作為分散式帳本成功的典範案例,區塊鏈向我們展示了他去中心化、不可竄改…等大幅相異於傳統資訊系統的特性,令人目眩神迷,但也因為和傳統概念的迥異,系統發展的過程也帶來了新的挑戰。雖然區塊鏈的應用方興未艾,但也可能是對於區塊鏈概念掌握的不足,仍有許多區塊鏈應用仍在摸索的階段,甚至出現了為區塊鏈而區塊鏈的不合理設計。因此本研究從發展區塊鏈應用系統的過程中,累積了一些經驗,企圖提出一個泛用型的區塊鏈應用發展架構,經由逐項檢視,協助釐清應用系統發展的疑點,讓區塊鏈的開發人員,有一個基本依循的途徑。
本研究同時將一個案例-食品履歷追溯的應用(校園食材系統),套用在這個發展架構之上,以檢視其運作的適切性。選用這個案例,固然一方面希望經由案例的實證檢視後,能讓這個架構更為適切於實務的運用,另一方面也是有些特別考慮。要能完全達到食品履歷追溯的效果,單靠區塊鏈技術是做不到的,還需要其他相關技術與機制的配合。綜觀目前區塊鏈系統的應用項目,除了比特幣之外,大部分仍脫離不了既有應用的範疇,因此面臨的問題是,如果過去系統運作還過得去,改用區塊鏈技術的優異性何在?考慮引進區塊鏈技術來做應用時,是否也應考慮該問題能被解決的程度有多高,才不至於做出來的區塊鏈應用都只淪為驗證技術的示範案例罷了。 The emerging technology of blockchain brings great inspiration to the information industry. As a success model of distributed ledger technology, it shows us some special characteristics, decentralized system, immutability, fast settlement…, which is quite different from the traditional information systems. It also brings some new challenges to the application developers. This research has accumulated some experience in the process of developing the blockchain application system, and attempts to propose a generic blockchain application framework. It includes evaluation rules whether the application is suitable for blockchain technology and some design guidance, so the application developers can follow easily. This research will also apply a case study, food traceability application (campus food system), to this development structure to examine the relevance of its operations. The selection of this case hopes that after the empirical review of the case, this structure can be more suitable for practical use. |
