  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>

 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>

 127       <div class="body">
 128         <p><a href="http://bitcoin.org/">Bitcoin</a> er mye i mediene for
 129 tiden.  Jeg følger med via Mylder for å finne
 130 <a href="http://mylder.no/?drill=bitcoin">artikler som omtaler
 131 temaet</a>, og takket være dette oppdaget jeg at stortingsrepresentant
 132 Ketil Solvik-Olsen fra FrP nylig har spurt finansminister Sigbjørn
 133 Johnsen om hans syn på Bitcoin, og
 134 <a href="http://www.stortinget.no/no/Saker-og-publikasjoner/Sporsmal/Skriftlige-sporsmal-og-svar/Skriftlig-sporsmal/?qid=57052">fått
 135 svar for noen dager siden</a>.  Jeg bet meg spesielt merke til
 136 følgende formulering fra finansministeren:</p>
 137
 138 <p><blockquote>
 139 «Det er også utfordringer ved at handel med Bitcoins er uregulert og
 140 at transaksjonene er anonyme.»
 141 </blockquote></p>
 142
 143 <p>At Bitcoin er anonymt er en myte som spres av både journalister og
 144 andre, så det er ikke veldig overraskende at også finansministeren har
 145 gått på limpinnen.  Det er dog litt rart, da jeg håper at
 146 finansdepartementet ikke baserer seg på rykter og myter når de
 147 besvarer Stortinget.  Men du trenger ikke bare tro på meg som kilde
 148 til påstanden om at Bitcoin ikke er anonymt.  Sondre Rønjom har
 149 <a href="http://blogg.nsm.stat.no/archives/3241">via Sikkerhetsbloggen
 150 hos Nasjonal Sikkerhetsmyndighet</a> uttalt følgende:</p>
 151
 152 <p><blockquote>
 153 «At [bitcoin] i utgangspunktet
 154 <a href="http://arxiv.org/abs/1107.4524"><em>ikke</em> er anonymt</a>,
 155 kommer kanskje som en overraskelse på mange.»
 156 </blockquote></p>
 157
 158 <p>Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle på
 159 Internet, og en må legge svært mye innsats inn hvis en skal hindre at
 160 nettverksanalyse av transaksjonsloggene kan brukes til å identifisere
 161 brukerne.  F.eks. kan en enkelt se hva jeg har mottatt til min
 162 offentliggjorte mottaksadresse ved å besøke blockexplorer og slå opp
 163 adressen
 164 <a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>.
 165 Det virker dermed på meg ganske klart at å påstå at
 166 Bitcoin-transaksjoner er anonyme strengt tatt er å føre Stortinget bak
 167 lyset.</p>
 168
 169 <p>Finansministeren er ikke den eneste som har latt seg forlede av
 170 medieomtalen.  I spørsmålet fra Hr. Solvik-Olsen skriver han at «For
 171 noen dager siden kom den første bitcoin-minibanken på Kypros», hvilket
 172 så vidt jeg har klart å finne ut ikke er riktig.  Det er annonsert
 173 planer om en slik minibank (fra
 174 <a href="http://www.bitcoinatm.com/">BitcoinATM</a>), men jeg finner
 175 intet tegn til at en slik minibank er utplassert noe sted.</p>

 178 mine aktiviteter, så setter jeg pris på Bitcoin-donasjoner til min

 203 bitcoin related blog post</a> mentioned that the new
 204 <a href="http://packages.qa.debian.org/bitcoin">bitcoin package</a> for
 205 Debian was waiting in NEW.  It was accepted by the Debian ftp-masters
 206 2013-01-19, and have been available in unstable since then.  It was
 207 automatically copied to Ubuntu, and is available in their Raring
 208 version too.</p>
 209
 210 <p>But there is a strange problem with the build that block this new
 211 version from being available on the i386 and kfreebsd-i386
 212 architectures.  For some strange reason, the autobuilders in Debian
 213 for these architectures fail to run the test suite on these
 214 architectures (<a href="http://bugs.debian.org/672524">BTS #672524</a>).
 215 We are so far unable to reproduce it when building it manually, and
 216 no-one have been able to propose a fix.  If you got an idea what is
 217 failing, please let us know via the BTS.</p>
 218
 219 <p>One feature that is annoying me with of the bitcoin client, because
 220 I often run low on disk space, is the fact that the client will exit
 221 if it run short on space (<a href="http://bugs.debian.org/696715">BTS
 222 #696715</a>).  So make sure you have enough disk space when you run

 248         <p>Let me start by wishing you all marry Christmas and a happy new
 249 year!  I hope next year will prove to be a good year.</p>
 250
 251 <p><a href="http://www.bitcoin.org/">Bitcoin</a>, the digital
 252 decentralised "currency" that allow people to transfer bitcoins
 253 between each other with minimal overhead, is a very interesting
 254 experiment.  And as I wrote a few days ago, the bitcoin situation in
 255 <a href="http://www.debian.org/">Debian</a> is about to improve a bit.
 256 The <a href="http://packages.qa.debian.org/bitcoin">new debian source
 257 package</a> (version 0.7.2-2) was uploaded yesterday, and is waiting
 258 in <a href="http://ftp-master.debian.org/new.html">the NEW queue</A>
 259 for one of the ftpmasters to approve the new bitcoin-qt package
 260 name.</p>
 261
 262 <p>And thanks to the great work of Jonas and the rest of the bitcoin
 263 team in Debian, you can easily test the package in Debian Squeeze
 264 using the following steps to get a set of working packages:</p>
 265
 266 <blockquote><pre>
 267 git clone git://git.debian.org/git/collab-maint/bitcoin
 268 cd bitcoin
 269 DEB_MAINTAINER_MODE=1 DEB_BUILD_OPTIONS=noupnp fakeroot debian/rules clean
 270 DEB_BUILD_OPTIONS=noupnp git-buildpackage --git-ignore-new
 271 </pre></blockquote>
 272
 273 <p>You might have to install some build dependencies as well.  The
 274 list of commands should give you two packages, bitcoind and
 275 bitcoin-qt, ready for use in a Squeeze environment.  Note that the
 276 client will download the complete set of bitcoin "blocks", which need
 277 around 5.6 GiB of data on my machine at the moment.  Make sure your
 278 ~/.bitcoin/ directory have lots of spare room if you want to download
 279 all the blocks.  The client will warn if the disk is getting full, so
 280 there is not really a problem if you got too little room, but you will
 281 not be able to get all the features out of the client.</p>

 305       <div class="body">
 306         <p>It has been a while since I wrote about
 307 <a href="http://www.bitcoin.org/">bitcoin</a>, the decentralised
 308 peer-to-peer based crypto-currency, and the reason is simply that I
 309 have been busy elsewhere.  But two days ago, I started looking at the
 310 state of <a href="http://packages.qa.debian.org/bitcoin">bitcoin in
 311 Debian</a> again to try to recover my old bitcoin wallet.  The package
 312 is now maintained by a
 313 <a href="https://alioth.debian.org/projects/pkg-bitcoin/">team of
 314 people</a>, and the grunt work had already been done by this team.  We
 315 owe a huge thank you to all these team members. :)
 316 But I was sad to discover that the bitcoin client is missing in
 317 Wheezy.  It is only available in Sid (and an outdated client from
 318 backports).  The client had several RC bugs registered in BTS blocking
 319 it from entering testing.  To try to help the team and improve the
 320 situation, I spent some time providing patches and triaging the bug
 321 reports.  I also had a look at the bitcoin package available from Matt
 322 Corallo in a
 323 <a href="https://launchpad.net/~bitcoin/+archive/bitcoin">PPA for
 324 Ubuntu</a>, and moved the useful pieces from that version into the
 325 Debian package.</p>
 326
 327 <p>After checking with the main package maintainer Jonas Smedegaard on
 328 IRC, I pushed several patches into the collab-maint git repository to
 329 improve the package.  It now contains fixes for the RC issues (not from
 330 me, but fixed by Scott Howard), build rules for a Qt GUI client
 331 package, konqueror support for the bitcoin: URI and bash completion
 332 setup.  As I work on Debian Squeeze, I also created
 333 <a href="http://lists.alioth.debian.org/pipermail/pkg-bitcoin-devel/Week-of-Mon-20121217/000041.html">a
 334 patch to backport</a> the latest version.  Jonas is going to look at
 335 it and try to integrate it into the git repository before uploading a
 336 new version to unstable.
 337
 338 <p>I would very much like bitcoin to succeed, to get rid of the
 339 centralized control currently exercised in the monetary system.  I
 340 find it completely unacceptable that the USA government is collecting
 341 transaction data for almost all international money transfers (most are done in USD and transaction logs shipped to the spooks), and
 342 that the major credit card companies can block legal money
 343 transactions to Wikileaks.  But for bitcoin to succeed, more people
 344 need to use bitcoins, and more people need to accept bitcoins when
 345 they sell products and services.  Improving the bitcoin support in
 346 Debian is a small step in the right direction, but not enough.
 347 Unfortunately the user experience when browsing the web and wanting to
 348 pay with bitcoin is still not very good.  The bitcoin: URI is a step
 349 in the right direction, but need to work in most or every browser in
 350 use.  Also the bitcoin-qt client is too heavy to fire up to do a
 351 quick transaction.  I believe there are other clients available, but
 352 have not tested them.</p>
 353
 354 <p>My
 355 <a href="http://people.skolelinux.org/pere/blog/Now_accepting_bitcoins___anonymous_and_distributed_p2p_crypto_money.html">experiment
 356 with bitcoins</a> showed that at least some of my readers use bitcoin.
 357 I received 20.15 BTC so far on the address I provided in my blog two
 358 years ago, as can be
 359 <a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">seen
 360 on the blockexplorer service</a>.  Thank you everyone for your

 387         <p>Slashdot just ran a story about the European Central Bank (ECB)
 388 <a href="http://www.ecb.europa.eu/pub/pdf/other/virtualcurrencyschemes201210en.pdf">releasing
 389 a report (PDF)</a> about virtual currencies and
 390 <a href="http://www.bitcoin.org/">bitcoin</a>.  It is interesting to
 391 see how a member of the bitcoin community
 392 <a href="http://blog.bitinstant.com/blog/2012/10/30/the-ecb-report-on-bitcoin-and-virtual-currencies.html">receive
 393 the report</a>.  As for the future, I suspect the central banks and
 394 the governments will outlaw bitcoin if it gain any popularity, to avoid
 395 competition.  My thoughts go to the
 396 <a href="http://en.wikipedia.org/wiki/Wörgl">Wörgl experiment</a> with
 397 negative inflation on cash which was such a success that it was
 398 terminated by the Austrian National Bank in 1933.  A successful
 399 alternative would be a threat to the current money system and gain
 400 powerful forces to work against it.</p>
 401
 402 <p>While checking out the current status of bitcoin, I also discovered
 403 that the community already seem to have
 404 <a href="http://www.theverge.com/2012/8/27/3271637/bitcoin-savings-trust-pyramid-scheme-shuts-down">experienced
 405 its first pyramid game / Ponzi scheme</a>.  Not very surprising, given
 406 how members of "small" communities tend to trust each other.  I guess
 407 enterprising crocks will try again and again, as they do anywhere
 408 wealth is available.</p>

 429         <p>As I continue to explore
 430 <a href="http://www.bitcoin.org/">BitCoin</a>, I've starting to wonder
 431 what properties the system have, and how it will be affected by laws
 432 and regulations here in Norway.  Here are some random notes.</p>
 433
 434 <p>One interesting thing to note is that since the transactions are
 435 verified using a peer to peer network, all details about a transaction
 436 is known to everyone.  This means that if a BitCoin address has been
 437 published like I did with mine in my initial post about BitCoin, it is
 438 possible for everyone to see how many BitCoins have been transfered to
 439 that address.  There is even a web service to look at the details for
 440 all transactions.  There I can see that my address
 441 <a href="http://blockexplorer.com/address/15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a>
 442 have received 16.06 Bitcoin, the
 443 <a href="http://blockexplorer.com/address/1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3">1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3</a>
 444 address of Simon Phipps have received 181.97 BitCoin and the address
 445 <a href="http://blockexplorer.com/address/1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt">1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt</A>
 446 of EFF have received 2447.38 BitCoins so far.  Thank you to each and
 447 every one of you that donated bitcoins to support my activity. The
 448 fact that anyone can see how much money was transfered to a given
 449 address make it more obvious why the BitCoin community recommend to
 450 generate and hand out a new address for each transaction.  I'm told
 451 there is no way to track which addresses belong to a given person or
 452 organisation without the person or organisation revealing it
 453 themselves, as Simon, EFF and I have done.</p>
 454
 455 <p>In Norway, and in most other countries, there are laws and
 456 regulations limiting how much money one can transfer across the border
 457 without declaring it.  There are money laundering, tax and accounting
 458 laws and regulations I would expect to apply to the use of BitCoin.
 459 If the Skolelinux foundation
 460 (<a href="http://linuxiskolen.no/slxdebianlabs/donations.html">SLX
 461 Debian Labs</a>) were to accept donations in BitCoin in addition to
 462 normal bank transfers like EFF is doing, how should this be accounted?
 463 Given that it is impossible to know if money can cross the border or
 464 not, should everything or nothing be declared?  What exchange rate
 465 should be used when calculating taxes?  Would receivers have to pay
 466 income tax if the foundation were to pay Skolelinux contributors in
 467 BitCoin?  I have no idea, but it would be interesting to know.</p>
 468
 469 <p>For a currency to be useful and successful, it must be trusted and
 470 accepted by a lot of users.  It must be possible to get easy access to
 471 the currency (as a wage or using currency exchanges), and it must be
 472 easy to spend it.  At the moment BitCoin seem fairly easy to get
 473 access to, but there are very few places to spend it.  I am not really
 474 a regular user of any of the vendor types currently accepting BitCoin,
 475 so I wonder when my kind of shop would start accepting BitCoins.  I
 476 would like to buy electronics, travels and subway tickets, not herbs
 477 and books. :) The currency is young, and this will improve over time
 478 if it become popular, but I suspect regular banks will start to lobby
 479 to get BitCoin declared illegal if it become popular.  I'm sure they
 480 will claim it is helping fund terrorism and money laundering (which
 481 probably would be true, as is any currency in existence), but I
 482 believe the problems should be solved elsewhere and not by blaming
 483 currencies.</p>
 484
 485 <p>The process of creating new BitCoins is called mining, and it is
 486 CPU intensive process that depend on a bit of luck as well (as one is
 487 competing against all the other miners currently spending CPU cycles
 488 to see which one get the next lump of cash).  The "winner" get 50
 489 BitCoin when this happen.  Yesterday I came across the obvious way to
 490 join forces to increase ones changes of getting at least some coins,
 491 by coordinating the work on mining BitCoins across several machines
 492 and people, and sharing the result if one is lucky and get the 50
 493 BitCoins.  Check out
 494 <a href="http://www.bluishcoder.co.nz/bitcoin-pool/">BitCoin Pool</a>
 495 if this sounds interesting.  I have not had time to try to set up a
 496 machine to participate there yet, but have seen that running on ones
 497 own for a few days have not yield any BitCoins througth mining
 498 yet.</p>
 499
 500 <p>Update 2010-12-15: Found an <a
 501 href="http://inertia.posterous.com/reply-to-the-underground-economist-why-bitcoi">interesting
 502 criticism</a> of bitcoin.  Not quite sure how valid it is, but thought
 503 it was interesting to read.  The arguments presented seem to be
 504 equally valid for gold, which was used as a currency for many years.</p>

 526 <a href="http://www.salon.com/news/opinion/glenn_greenwald/2010/12/06/wikileaks/index.html">governmental
 527 attacks</a> on Wikileak and
 528 <a href="http://www.salon.com/technology/dan_gillmor/2010/12/06/war_on_speech">free
 529 speech</a>, it has become obvious that PayPal, visa and mastercard can
 530 not be trusted to handle money transactions.
 531 A blog post from
 532 <a href="http://webmink.com/2010/12/06/now-accepting-bitcoin/">Simon
 533 Phipps on bitcoin</a> reminded me about a project that a friend of
 534 mine mentioned earlier.  I decided to follow Simon's example, and get
 535 involved with <a href="http://www.bitcoin.org/">BitCoin</a>.  I got
 536 some help from my friend to get it all running, and he even handed me
 537 some bitcoins to get started.  I even donated a few bitcoins to Simon
 538 for helping me remember BitCoin.</p>
 539
 540 <p>So, what is bitcoins, you probably wonder?  It is a digital
 541 crypto-currency, decentralised and handled using peer-to-peer
 542 networks.  It allows anonymous transactions and prohibits central
 543 control over the transactions, making it impossible for governments
 544 and companies alike to block donations and other transactions.  The
 545 source is free software, and while the key dependency wxWidgets 2.9
 546 for the graphical user interface is missing in Debian, the command
 547 line client builds just fine.  Hopefully Jonas
 548 <a href="http://bugs.debian.org/578157">will get the package into
 549 Debian</a> soon.</p>
 550
 551 <p>Bitcoins can be converted to other currencies, like USD and EUR.
 552 There are <a href="http://www.bitcoin.org/trade">companies accepting
 553 bitcoins</a> when selling services and goods, and there are even
 554 currency "stock" markets where the exchange rate is decided.  There
 555 are not many users so far, but the concept seems promising.  If you
 556 want to get started and lack a friend with any bitcoins to spare,
 557 you can even get
 558 <a href="https://freebitcoins.appspot.com/">some for free</a> (0.05
 559 bitcoin at the time of writing).  Use
 560 <a href="http://www.bitcoinwatch.com/">BitcoinWatch</a> to keep an eye
 561 on the current exchange rates.</p>
 562
 563 <p>As an experiment, I have decided to set up bitcoind on one of my
 564 machines.  If you want to support my activity, please send Bitcoin
 565 donations to the address
 566 <b>15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</b>.  Thank you!</p>
