【Abstract】Bitcoin is a digital currency whose transactions are stored into a public ledger, called blockchain, that can be viewed as a directed graph with more than 70 million nodes, where each node represents a transaction and each edge represents Bitcoins flowing from one transaction to another one. We describe a system for the visual analysis of how and when a flow of Bitcoins mixes with other flows in the transaction graph. Such a system relies on high- level metaphors for the representation of the graph and the size and characteristics of transactions, allowing for high level analysis of big portions of it.

【标题】BitConeView:比特币交易图中的流的可视化
【摘要】比特币是一种数字货币，其交易存储在一个名为区块链的公共账本中，可以看作是一个有向图，有7000万个节点，每个节点代表一笔交易，每个边代表比特币从一笔交易流向另一笔交易。我们描述了一个系统，用于可视化分析比特币流如何以及何时与交易图中的其他流混合。这样的系统依赖于高级的隐喻来表示图形以及事务的大小和特征，允许对其大部分进行高级分析。
