标题： Impact of a Blockchain-based Universal Basic Income Pilot: The case of Circles UBI currency

摘要： UBI 圈子是一种基于区块链的社区货币系统（CCS），自 2021 年 10 月起在柏林（德国）开始运作。 发起该项目的圈子合作社（Circles Coop）于 2023 年 12 月关闭。 本文展示了我们在 2023 年 10 月至 11 月期间进行的一项调查结果。 受访者是二十五位以各种方式参与圈子网络的个人。 主要出现的主题指出，他们的参与深受对圈子社区价值观和理想的认同所驱动。 在他们之中，我们选择了五个具有代表性的个人档案，这些档案因其参与类型和程度的不同而脱颖而出。 最后，我们报告了一些经济联系的故事，表明采用本地社区货币存在正外部性。 据我们所知，这是首个针对作为社区货币设计的普遍基本收入且采用区块链技术的定性研究。 这个试点项目因其采用的先进技术和社会创新而成为一项显著的实验。 事实上，据我们所知，基本收入与本地货币特征的整合仅在另外两个案例中（巴西马里卡和西班牙巴塞罗那）进行了试验，并且它们都没有采用去中心化账本系统。 在这项工作中，我们试图概述在约两年的活动后显现的优势和劣势。 因此，未来对该领域感兴趣的学者和活动家将找到有价值的信息。 显示英文摘要

摘要： Circles UBI is a blockchain-based Community Currency System (CCS) that has been active in Berlin (Germany) since October 2021. The Circles Coop, which launched the project in 2021, was shut down in December 2023. In this paper, we show the results of a survey carried out between October and November 2023. The respondents were twenty-five individuals involved in various ways in the Circles' network. The main emerging narrative points out how their participation was deeply motivated by their identification with the values and ideals of the Circles community. Among them, we selected five profiles that stood for their difference in type and degree of involvement. Finally, we report some stories of economic linkages that suggest a positive externality in adopting a local community currency. To our knowledge, this is the first qualitative study of a universal basic income designed as a community currency and adopting blockchain technology. This pilot project was a remarkable experiment for its adopted advanced technological and social innovations. In fact, as far as we know, the integration of basic income and local currency features has been experimented with only in two other cases (Maric\'a, Brazil and Barcelona, Spain) and none of them adopted a decentralized ledger system. In this work, we try to outline strengths and weaknesses that emerged after about two years of activity. For this reason, future researchers and activists interested in this field will find valuable information.
