行動時間銀行在區塊鏈上的系統開發應用於社區高齡照護

Abstract

本研究旨在開發一種基於區塊鏈技術的移動時間銀行系統（Mobile Time-Banking system on Blockchain, MTBB），該系統可以通過相互服務交換以追踪社區高齡照護的服務交易記錄。 MTBB 的開發，是為了使志工組織（企業社會責任組織或非營利組織）能夠向參與志工活動的志工發行專有的時間幣。此研究開發了帶有與 MultiChain 區塊鏈技術整合的智慧型手機應用程式及資料庫應用程式 (MultiChain是一區塊鏈技術軟體)。帶有服務交易資料的詮釋資料或後設資料 (metadata) 儲存在 MultiChain 區塊鏈的區塊中，因此交易記錄是不可變的。 學者Cahn 的時間銀行指南被應用於開發這個 MTBB，其中整合了 MultiChain 區塊鏈技術以用於追踪服務交易記錄。此研究還將一對一的相互服務交換和提供志工活動的相關服務整合在一起，以讓志工組織發行專有時間幣。借助區塊鏈交易追踪機制，可以追踪和分析組織內部或組織內的所有高齡照護服務記錄，以顯示其與聯合國某些可持續發展目標的一致性。

This study aims to develop a mobile time-banking system on blockchain (MTBB), which can track service transaction records for community elderly care via mutual service exchange. The MTBB was developed to enable organizations, either corporate-social-responsibility organizations or nonprofit organizations (NPOs) to issue proprietary time tokens to members who participate in the organizations’ volunteer activities. Database applications with smartphone apps integrated with MultiChain blockchain technology were developed. Metadata with the service transaction information are stored in the MultiChain blocks so that the transaction records are immutable and can be analyzed in the future. Cahn’s time-banking guidelines were applied in developing this MTBB with MultiChain blockchain technology integrated for tracking service transaction records. The study also combines one-to-one mutual service exchange with organizations which offer volunteer activities and issue proprietary time tokens. With the blockchain transaction tracking mechanism, all elderly care service records via or within organizations can be tracked and analyzed to show their alignment with some of the Sustainable Development Goals of the United Nations.
