=== 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.
