  This work is organized as follows. In the first section we review the prior
work and we have obtained our data. Next, we will look at address reuse in the
Bitcoin network. We show that a great portion of users reuse their addresses
which could enable us to cluster the addresses and attribute them to single
users. Next, we will categorize the nodes based on their role in the network as
a customer or seller. Finally, we do a study of nodes and network performance.
