Bitcoin Deanonymization

How's it going with that 'online bitcoin course', last mentioned in Going Deeper into Bitcoin (March 2016)? At that time I wrote,
It took me exactly a week to work through the first two lectures. I'm sure that I won't be able to maintain this pace week after week, and I only skimmed the readings.

I've reached lecture six where I found an interesting image in '6.2 Overview of Bitcoin Deanonymization'. At about 11:40 into the video, the following chart is shown.

A similar chart can be found in the paper A Fistful of Bitcoins: Characterizing Payments Among Men with No Names Sarah Meiklejohn et al. The caption there (p.9) says,

Figure 6: A visualization of the user network. The area of the cluster represents the external incoming value; i.e., the bitcoins received from other clusters but not itself, and for an edge to appear between two nodes there must have been at least 200 transactions between them. The nodes are colored by category: blue nodes are mining pools; orange are fixed-rate exchanges; green are wallets; red are vendors; purple are (bank) exchanges; brown are gambling; pink are investment schemes; and grey are uncategorized.

Also interesting -- to me, at least -- are the 16 bitcoin services listed in the chart:-

bitcoin.de, bitcoinica, bitmit, bitpay, bitstamp, btc-e, deepbit, gibse, instawallet, mtgox, mybitcoin, okpay, ozcoin, satoshi btc dice, silk road, slush

Since few of those are household names, I'll look at them in another post.
