Abstract:	智能合約的不可變性是區塊鏈的一個重要特性。這種不可變性阻止了已部署的智能合約被惡意修改和操縱，也可以保證合約的執行遵循了用戶和合約所有者的初始協議。然而，在合約部署後，也相對的無法靈活地更改程式代碼，很難修復開發缺陷或改進不良設計和實作新的功能。此外，因為智能合約需要根據當前的市場狀態來修改其行為，這也限制了智能合約在金融投資方面的應用。因此，本研究在信託帳戶數位資產平台上實現了可修改智能合約框架的概念，展示了無需重新部署整個合約即可重新設計智能合約的靈活性和調整性。這個數位平台可以隨著新應用、新用戶、新功能甚至新的應用控制流程進行調整。特別是，我們通過信託帳戶發行新的代幣，使得失效的賬戶可以由指定的繼承人重新領取。我們還實現了兩個應用：人工智能投資和年金保險，並以兩個應用為例，展示如何利用該平台進一步開發數位資產應用。 The immutability of smart contract is a significant feature of blockchain. The immutability prevents deployed smart contracts from malicious modification and manipulations, guaranteeing the contract execution obeying the initial agreements of both sides: users and contract owners. On the other hand, without the flexibility of changing codes after the deployment, it is hard to fix software defects or improve poor design and utility functions. Furthermore, the restriction also limits smart contract applications on financial investment while they are required to modify their behaviors according to the current market states. This work realizes the concept of modifiable smart contract framework on digital asset platform with account in trust, demonstrating the flexibility and adjustment to redesign smart contracts without redeployment of the whole contract. We implement the digital platform can be adjusted with new applications, new users, new functions and even new control flows of applications. Particularly, we issue new tokens with account in trust, such that a dead account can be re-claimed by designated survivors. We also implemented two applications: AI investment and annuity insurance as examples to show how digital asset applications can be further developed with the platform.
