【Abstract】Many blockchain-based cryptocurrencies provide users with online blockchain explorers for viewing online transaction data. How-ever, traditional blockchain explorers mostly present transaction information in textual and tabular forms. Such forms make understanding cryptocurrency transaction mechanisms difficult for novice users (NUsers). They are also insufficiently informative for experienced users (EUsers) to recognize advanced transaction information. This study introduces a new online cryptocurrency transaction data viewing tool called SilkViser. Guided by detailed scenario and requirement analyses, we create a series of appreciating visualization designs, such as paper ledger-inspired block and blockchain visualizations and ancient copper coin-inspired transaction visualizations, to help users understand cryptocurrency transaction mechanisms and recognize advanced transaction information. We also provide a set of lightweight interactions to facilitate easy and free data exploration. Moreover, a controlled user study is conducted to quantitatively evaluate the usability and effectiveness of SilkViser. Results indicate that SilkViser can satisfy the requirements of NUsers and EUsers. Our visualization designs can compensate for the inexperience of NUsers in data viewing and attract potential users to participate in cryptocurrency transactions.

【标题】SilkViser:一个基于区块链的加密货币交易数据的可视化浏览器
【摘要】许多基于区块链的加密货币为用户提供在线区块链浏览器，以查看在线交易数据。然而，传统的区块链探索器大多以文本和表格形式显示事务信息。这种形式使得新手用户(NUsers)很难理解加密货币交易机制。对于有经验的用户(EUsers)来说，这些信息也不足以识别高级交易信息。这项研究引入了一种新的在线加密货币交易数据查看工具，称为SilkViser。在详细的场景和需求分析的指导下，我们创建了一系列欣赏可视化设计，如纸质账本启发区块和区块链启发可视化，古代铜币启发交易可视化，帮助用户理解加密货币交易机制，识别高级交易信息。我们还提供了一组轻量级交互，以促进轻松和免费的数据探索。此外，还进行了一项控制用户研究，以定量评估SilkViser的可用性和有效性。结果表明，SilkViser能够满足NUsers和EUsers的需求。我们的可视化设计可以弥补NUsers在数据查看方面的经验不足，并吸引潜在用户参与加密货币交易。
