  31         <p>Bitcoin is a incredible use of peer to peer communication and
  32 encryption, allowing direct and immediate money transfer without any
  33 central control.  It is sometimes claimed to be ideal for illegal
  34 activity, which I believe is quite a long way from the truth.  At least
  35 I would not conduct illegal money transfers using a system where the
  36 details of every transaction are kept forever.  This point is
  37 investigated in
  38 <a href="https://www.usenix.org/publications/login">USENIX ;login:</a>
  39 from December 2013, in the article
  40 "<a href="https://www.usenix.org/system/files/login/articles/03_meiklejohn-online.pdf">A
  41 Fistful of Bitcoins - Characterizing Payments Among Men with No
  42 Names</a>" by Sarah Meiklejohn, Marjori Pomarole,Grant Jordan, Kirill
  43 Levchenko, Damon McCoy, Geoffrey M. Voelker, and Stefan Savage.  They
  44 analyse the transaction log in the Bitcoin system, using it to find
  45 addresses belong to individuals and organisations and follow the flow
  46 of money from both Bitcoin theft and trades on Silk Road to where the
  47 money end up.  This is how they wrap up their article:</p>
  48
  49 <p><blockquote>
  50 <p>"To demonstrate the usefulness of this type of analysis, we turned
  51 our attention to criminal activity. In the Bitcoin economy, criminal
  52 activity can appear in a number of forms, such as dealing drugs on
  53 Silk Road or simply stealing someone else’s bitcoins. We followed the
  54 flow of bitcoins out of Silk Road (in particular, from one notorious
  55 address) and from a number of highly publicized thefts to see whether
  56 we could track the bitcoins to known services. Although some of the
  57 thieves attempted to use sophisticated mixing techniques (or possibly
  58 mix services) to obscure the flow of bitcoins, for the most part
  59 tracking the bitcoins was quite straightforward, and we ultimately saw
  60 large quantities of bitcoins flow to a variety of exchanges directly
  61 from the point of theft (or the withdrawal from Silk Road).</p>
  62
  63 <p>As acknowledged above, following stolen bitcoins to the point at
  64 which they are deposited into an exchange does not in itself identify
  65 the thief; however, it does enable further de-anonymization in the
  66 case in which certain agencies can determine (through, for example,
  67 subpoena power) the real-world owner of the account into which the
  68 stolen bitcoins were deposited.  Because such exchanges seem to serve
  69 as chokepoints into and out of the Bitcoin economy (i.e., there are
  70 few alternative ways to cash out), we conclude that using Bitcoin for
  71 money laundering or other illicit purposes does not (at least at
  72 present) seem to be particularly attractive."</p>
  73 </blockquote><p>
  74
  75 <p>These researches are not the first to analyse the Bitcoin
  76 transaction log.  The 2011 paper
  77 "<a href="http://arxiv.org/abs/1107.4524">An Analysis of Anonymity in
  78 the Bitcoin System</A>" by Fergal Reid and Martin Harrigan is
  79 summarized like this:</p>
  80
  81 <p><blockquote>
  82 "Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a
  83 complicated issue. Within the system, users are identified by
  84 public-keys only. An attacker wishing to de-anonymize its users will
  85 attempt to construct the one-to-many mapping between users and
  86 public-keys and associate information external to the system with the
  87 users. Bitcoin tries to prevent this attack by storing the mapping of
  88 a user to his or her public-keys on that user's node only and by
  89 allowing each user to generate as many public-keys as required. In
  90 this chapter we consider the topological structure of two networks
  91 derived from Bitcoin's public transaction history. We show that the
  92 two networks have a non-trivial topological structure, provide
  93 complementary views of the Bitcoin system and have implications for
  94 anonymity. We combine these structures with external information and
  95 techniques such as context discovery and flow analysis to investigate
  96 an alleged theft of Bitcoins, which, at the time of the theft, had a
  97 market value of approximately half a million U.S. dollars."
  98 </blockquote></p>
  99
 100 <p>I hope these references can help kill the urban myth that Bitcoin
 101 is anonymous.  It isn't really a good fit for illegal activites.  Use
 102 cash if you need to stay anonymous, at least until regular DNA
 103 sampling of notes and coins become the norm. :)</p>

 106 activities, please send Bitcoin donations to my address

 127       <div class="body">
 128         <p>I work at the <a href="http://www.uio.no/">University of Oslo</a>
 129 looking after the computers, mostly on the unix side, but in general
 130 all over the place.  I am also a member (and currently leader) of
 131 <a href="http://www.nuug.no/">the NUUG association</a>, which in turn
 132 make me a member of <a href="http://www.usenix.org/">USENIX</a>.  NUUG
 133 is an member organisation for us in Norway interested in free
 134 software, open standards and unix like operating systems, and USENIX
 135 is a US based member organisation with similar targets.  And thanks to
 136 these memberships, I get all issues of the great USENIX magazine
 137 <a href="https://www.usenix.org/publications/login">;login:</a> in the
 138 mail several times a year.  The magazine is great, and I read most of
 139 it every time.</p>
 140
 141 <p>In the last issue of the USENIX magazine ;login:, there is an
 142 article by <a href="http://www.skendric.com/">Stuart Kendrick</a> from
 143 Fred Hutchinson Cancer Research Center titled
 144 "<a href="https://www.usenix.org/publications/login/october-2012-volume-37-number-5/what-takes-us-down">What
 145 Takes Us Down</a>" (longer version also
 146 <a href="http://www.skendric.com/problem/incident-analysis/2012-06-30/What-Takes-Us-Down.pdf">available
 147 from his own site</a>), where he report what he found when he
 148 processed the outage reports (both planned and unplanned) from the
 149 last twelve years and classified them according to cause, time of day,
 150 etc etc.  The article is a good read to get some empirical data on
 151 what kind of problems affect a data centre, but what really inspired
 152 me was the kind of reporting they had put in place since 2000.<p>
 153
 154 <p>The centre set up a mailing list, and started to send fairly
 155 standardised messages to this list when a outage was planned or when
 156 it already occurred, to announce the plan and get feedback on the
 157 assumtions on scope and user impact.  Here is the two example from the
 158 article: First the unplanned outage:
 159
 160 <blockquote><pre>
 161 Subject:     Exchange 2003 Cluster Issues
 162 Severity:    Critical (Unplanned)
 163 Start:       Monday, May 7, 2012, 11:58
 164 End:         Monday, May 7, 2012, 12:38
 165 Duration:    40 minutes
 166 Scope:       Exchange 2003
 167 Description: The HTTPS service on the Exchange cluster crashed, triggering
 168              a cluster failover.
 169
 170 User Impact: During this period, all Exchange users were unable to
 171              access e-mail. Zimbra users were unaffected.
 172 Technician:  [xxx]
 173 </pre></blockquote>
 174
 175 Next the planned outage:
 176
 177 <blockquote><pre>
 178 Subject:     H Building Switch Upgrades
 179 Severity:    Major (Planned)
 180 Start:       Saturday, June 16, 2012, 06:00
 181 End:         Saturday, June 16, 2012, 16:00
 182 Duration:    10 hours
 183 Scope:       H2 Transport
 184 Description: Currently, Catalyst 4006s provide 10/100 Ethernet to end-
 185              stations. We will replace these with newer Catalyst
 186              4510s.
 187 User Impact: All users on H2 will be isolated from the network during
 188              this work. Afterward, they will have gigabit
 189              connectivity.
 190 Technician:  [xxx]
 191 </pre></blockquote>
 192
 193 <p>He notes in his article that the date formats and other fields have
 194 been a bit too free form to make it easy to automatically process them
 195 into a database for further analysis, and I would have used ISO 8601
 196 dates myself to make it easier to process (in other words I would ask
 197 people to write '2012-06-16 06:00 +0000' instead of the start time
 198 format listed above).  There are also other issues with the format
 199 that could be improved, read the article for the details.</p>
 200
 201 <p>I find the idea of standardising outage messages seem to be such a
 202 good idea that I would like to get it implemented here at the
 203 university too.  We do register
 204 <a href="http://www.uio.no/tjenester/it/aktuelt/planlagte-tjenesteavbrudd/">planned
 205 changes and outages in a calendar</a>, and report the to a mailing
 206 list, but we do not do so in a structured format and there is not a
 207 report to the same location for unplanned outages.  Perhaps something
 208 for other sites to consider too?</p>
