| dc.description.abstract (摘要) | 隨著數位經濟的興起以及區塊鏈技術的進步，加上疫情後電子支付方式的普及，貨幣的流通從實體形式轉化為數位形態。本研究聚焦基於新加坡金融管理局提出的「特殊目的貨幣」（Purpose Bound Money, PBM）概念，探索一種可自訂使用條件的數位貨幣模型。本文設計了靈活的智能合約範本，利用Chainlink預言機技術獲取鏈外數據，實現數位貨幣在不同情境中的應用，提升其附加價值和市場適用性。
本文詳細解構了PBM的生命週期及其架構，介紹其角色功能和運作流程，並探討了PBM在多階段封裝和解封中的技術細節，展示如何透過智能合約和Chainlink技術來實現這些功能。實驗部分以政府發行的振興券和補助計畫為例，展示了PBM在強化可程式化貨幣功能方面的優勢。結果表明，PBM模型在實際開發和應用中具有很大的潛力，為未來可程式化貨幣的研究和創新發展奠定了基礎。
綜上所述，本文證明PBM模型的實際開發和應用潛力，為可程式化貨 幣的未來研究和創新發展奠定堅實的基礎，對於推動金融科技創新與發展具有 重要意義。 | zh_TW |
| dc.description.abstract (摘要) | Amidst the burgeoning digital economy and the advancement of blockchain technology, coupled with the proliferation of electronic payment methods post-pandemic, the circulation of currency has transitioned from physical to digital forms. This study focuses on exploring a programmable digital currency model based on the "Purpose Bound Money" (PBM) concept proposed by the Monetary Authority of Singapore. We have designed a flexible smart contract template that leverages Chainlink Oracle technology to acquire off-chain data, enabling the application of digital currency in various scenarios, thereby enhancing its added value and market applicability.
This paper deconstructs the lifecycle and architecture of PBM in detail, elucidating its functional roles and operational processes. It also delves into the technical intricacies of multi-stage encapsulation and unwrapping within PBM, demonstrating how these functionalities can be achieved through smart contracts and Chainlink technology. The experimental section uses subsidy programs as examples to showcase the advantages of PBM in enhancing programmable currency functionalities.
In summary, this paper substantiates the PBM model, establishing a robust foundation for future research and innovative development of programmable currency. | en_US |
