=== 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.

Joint work with Giuseppe Di Battista, Maurizio Patrignani,
Maurizio Pizzonia, Vincenzo Roselli, and Roberto Tamassia.

The paper will be presented at the forthcoming IEEE VizSec 2015 – “IEEE
Symposium on Visualization for Cyber Security” October 26, 2015 –
