Sarafu Community Inclusion Currency, 2020-2021

We describe a dataset of account information and transaction records for a digital community currency in Kenya. One unit of “Sarafu” is roughly equivalent in value to a Kenyan shilling. The Sarafu system has existed since 2010 and began operating digitally via USSD feature-code cellular technology in 2017. This dataset includes pseudonymized account information for around 55,000 users and records of all Sarafu transactions conducted from 25/01/2020 to 15/06/2021. User transactions capture various economic and financial activities such as purchases, transfers, and participation in savings and lending groups. So-called "chamas" are key to the operation of the Sarafu system and clearly labeled in the data. This dataset will contribute to research on the operation of community currencies, monetary systems, and economic networks in underdeveloped areas. The observation period includes the first year of the coronavirus pandemic and several documented pilot projects and development interventions.

我们介绍一个关于肯尼亚数字社区货币的账户信息与交易记录数据集。一单位“萨拉夫（Sarafu）”的价值大致相当于一肯尼亚先令。萨拉夫系统自2010年起存在，并于2017年通过非结构化补充数据业务（USSD）特征码蜂窝技术实现数字化运营。该数据集包含约55,000名用户的假名化账户信息，以及2020年1月25日至2021年6月15日期间所有萨拉夫交易的记录。用户交易涵盖多种经济与金融活动，例如购买、转账，以及参与储蓄和借贷小组。所谓的“查马（chamas）”是萨拉夫系统运营的关键，且在数据中被清晰标注。该数据集将为社区货币、货币体系及欠发达地区经济网络的运营研究提供助力。观测期涵盖新冠疫情第一年，以及若干有记录的试点项目与发展干预措施。
