比特币区块链技术是一种分布式节点分类账，授权匿名方之间的交易。它的关键参与者是矿工，他们使用计算能力来解决数学问题，以验证交易。由于分享了区块链的特征，挖掘是一种分散、透明和不受监管的做法，在人机交互中较少被探索，因此我们对矿工的动机和经历知之甚少，以及这些因素可能如何影响不同维度的信任。本文报道了对20名比特币矿工的采访，了解他们的做法和信任挑战。这些发现通过扩展区块链与信任相关的特征的探索，以及支撑挖掘的社会组织的竞争力维度，为人机界面理论做出了贡献。我们讨论了由于集中化和不诚实的管理员而导致的协作挖掘的风险，并总结了设计方面的启示，强调了协作挖掘中监视报酬分配的工具、跟踪数据中心的授权和声誉的工具以及支持分散池发展的工具的必要性。
Bitcoin blockchain technology is a distributed ledger of nodes authorizing transactions between anonymous parties. Its key actors are miners using computational power to solve mathematical problems for validating transactions. By sharing blockchain's characteristics, mining is a decentralized, transparent and unregulated practice, less explored in HCI, so we know little about miners' motivations and experiences, and how these may impact on different dimensions of trust. This paper reports on interviews with 20 bitcoin miners about their practices and trust challenges. Findings contribute to HCI theories by extending the exploration of blockchain's characteristics relevant to trust with the competitiveness dimension underpinning the social organization of mining. We discuss the risks of collaborative mining due to centralization and dishonest administrators, and conclude with design implications highlighting the need for tools monitoring the distribution of rewards in collaborative mining, tools tracking data centers' authorization and reputation, and tools supporting the development of decentralized pools.
