比特币是一种加密货币，在过去五年中受到越来越多的关注。它建立在一个去中心化的点对点系统之上，支持透明、快速、具有成本效益和不可逆转的交易，而无需信任第三方金融机构。然而，我们对人们使用比特币的动机和经验知之甚少。本文报道了对马来西亚20位比特币用户的采访，了解他们的经验和信任挑战。调查结果显示，比特币更多地被用作投机性投资或储蓄保护的价值储存。本文通过识别比特币的主要特征及其对信任的影响，如分散性，不受监管，嵌入式专业知识和声誉，以及交易的透明度，低成本和易于完成，推进了HCI信任理论。我们讨论不安全的交易，不诚实的交易者的风险及其缓解策略。本文的结论与设计的影响，包括支持双向交易的透明度，实现信任的工具，支持可逆交易的工具。
Bitcoin is a cryptocurrency which has received increasing interest over the last five years. Built upon a decentralized peer to peer system, it supports transparent, fast, cost effective, and irreversible transactions, without the need for trusting third party financial institutions. We know however little about people's motivation and experience with bitcoin currency. This paper reports on interviews with 20 bitcoin users in Malaysia about their experience and trust challenges. Findings show that bitcoins are used more as store of value for speculative investment or savings' protection. The paper advances the HCI theories on trust by identifying main bitcoin characteristics and their impact on trust, such as decentralization, unregulation, embedded expertise, and reputation, as well as transactions' transparency, low cost, and easiness to complete. We discuss insecure transactions, the risk of dishonest traders and its mitigating strategies. The paper concludes with design implications including support for the transparency of two-way transactions, tools for materializing trust, and tools for supporting reversible transactions.
