">Bitcoin
</a

15 tiden. Jeg følger med via Mylder for å finne
16 <a href=
"http://mylder.no/?drill=bitcoin
">artikler som omtaler
17 temaet
</a
>, og takket være dette oppdaget jeg at stortingsrepresentant
18 Ketil Solvik-Olsen fra FrP nylig har spurt finansminister Sigbjørn
19 Johnsen om hans syn på Bitcoin, og
20 <a href=
"http://www.stortinget.no/no/Saker-og-publikasjoner/Sporsmal/Skriftlige-sporsmal-og-svar/Skriftlig-sporsmal/?qid=
57052">fått
21 svar for noen dager siden
</a
>. Jeg bet meg spesielt merke til
22 følgende formulering fra finansministeren:
</p
>
24 <p
><blockquote
>
25 «Det er også utfordringer ved at handel med Bitcoins er uregulert og
26 at transaksjonene er anonyme.»
27 </blockquote
></p
>
29 <p
>At Bitcoin er anonymt er en myte som spres av både journalister og
30 andre, så det er ikke veldig overraskende at også finansministeren har
31 gått på limpinnen. Det er dog litt rart, da jeg håper at
32 finansdepartementet ikke baserer seg på rykter og myter når de
33 besvarer Stortinget. Men du trenger ikke bare tro på meg som kilde
34 til påstanden om at Bitcoin ikke er anonymt. Sondre Rønjom har
35 <a href=
"http://blogg.nsm.stat.no/archives/
3241">via Sikkerhetsbloggen
36 hos Nasjonal Sikkerhetsmyndighet
</a
> uttalt følgende:
</p
>
38 <p
><blockquote
>
39 «At [bitcoin] i utgangspunktet
40 <a href=
"http://arxiv.org/abs/
1107.4524"><em
>ikke
</em
> er anonymt
</a
>,
41 kommer kanskje som en overraskelse på mange.»
42 </blockquote
></p
>
44 <p
>Enhver bevegelse av Bitcoin er offentlig tilgjengelig for alle på
45 Internet, og en må legge svært mye innsats inn hvis en skal hindre at
46 nettverksanalyse av transaksjonsloggene kan brukes til å identifisere
47 brukerne. F.eks. kan en enkelt se hva jeg har mottatt til min
48 offentliggjorte mottaksadresse ved å besøke blockexplorer og slå opp
50 <a href=

">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b
</a
>.
51 Det virker dermed på meg ganske klart at å påstå at
52 Bitcoin-transaksjoner er anonyme strengt tatt er å føre Stortinget bak
55 <p
>Finansministeren er ikke den eneste som har latt seg forlede av
56 medieomtalen. I spørsmålet fra Hr. Solvik-Olseb skriver han at «For
57 noen dager siden kom den første bitcoin-minibanken på Kypros», hvilket
58 så vidt jeg har klart å finne ut ikke er riktig. Det er annonsert
59 planer om en slik minibank (fra

61 inten tegn til at en slik minibank er utplassert noe sted.

</a

115 between each other with minimal overhead, is a very interesting
116 experiment. And as I wrote a few days ago, the bitcoin situation in
117 <a href=
"http://www.debian.org/
">Debian
</a
> is about to improve a bit.
118 The
<a href=
"http://packages.qa.debian.org/bitcoin

119 package
</a

0.7.2-

">the NEW queue
</A
>
121 for one of the ftpmasters to approve the new bitcoin-qt package
124 <p
>And thanks to the great work of Jonas and the rest of the bitcoin
125 team in Debian, you can easily test the package in Debian Squeeze
126 using the following steps to get a set of working packages:
</p

128 <blockquote

135 <p
>You might have to install some build dependencies as well. The
136 list of commands should give you two packages, bitcoind and
137 bitcoin-qt, ready for use in a Squeeze environment. Note that the
138 client will download the complete set of bitcoin
"blocks
", which need
139 around
5.6 GiB of data on my machine at the moment. Make sure your
140 ~/.bitcoin/ directory have lots of spare room if you want to download
141 all the blocks. The client will warn if the disk is getting full, so
142 there is not really a problem if you got too little room, but you will
143 not be able to get all the features out of the client.

>It has been a while since I wrote about
157 <a href=
"http://www.bitcoin.org/
">bitcoin
</a
>, the decentralised
158 peer-to-peer based crypto-currency, and the reason is simply that I
159 have been busy elsewhere. But two days ago, I started looking at the
160 state of
<a href=
"http://packages.qa.debian.org/bitcoin
">bitcoin in
161 Debian
</a
> again to try to recover my old bitcoin wallet. The package
162 is now maintained by a
163 <a href=
"https://alioth.debian.org/projects/pkg-bitcoin/
">team of
164 people
</a
>, and the grunt work had already been done by this team. We
165 owe a huge thank you to all these team members. :)
166 But I was sad to discover that the bitcoin client is missing in
167 Wheezy. It is only available in Sid (and an outdated client from
168 backports). The client had several RC bugs registered in BTS blocking
169 it from entering testing. To try to help the team and improve the
170 situation, I spent some time providing patches and triaging the bug
171 reports. I also had a look at the bitcoin package available from Matt
173 <a href=
"https://launchpad.net/~bitcoin/+archive/bitcoin
">PPA for
174 Ubuntu
</a
>, and moved the useful pieces from that version into the
175 Debian package.
</p
>
177 <p
>After checking with the main package maintainer Jonas Smedegaard on
178 IRC, I pushed several patches into the collab-maint git repository to
179 improve the package. It now contains fixes for the RC issues (not from
180 me, but fixed by Scott Howard), build rules for a Qt GUI client
181 package, konqueror support for the bitcoin: URI and bash completion
182 setup. As I work on Debian Squeeze, I also created
183 <a href=
"http://lists.alioth.debian.org/pipermail/pkg-bitcoin-devel/Week-of-Mon-
20121217/
000041.html
">a
184 patch to backport
</a
> the latest version. Jonas is going to look at
185 it and try to integrate it into the git repository before uploading a
186 new version to unstable.
188 <p
>I would very much like bitcoin to succeed, to get rid of the
189 centralized control currently exercised in the monetary system. I
190 find it completely unacceptable that the USA government is collecting
191 transaction data for almost all international money transfers (most are done in USD and transaction logs shipped to the spooks), and
192 that the major credit card companies can block legal money
193 transactions to Wikileaks. But for bitcoin to succeed, more people
194 need to use bitcoins, and more people need to accept bitcoins when
195 they sell products and services. Improving the bitcoin support in
196 Debian is a small step in the right direction, but not enough.
197 Unfortunately the user experience when browsing the web and wanting to
198 pay with bitcoin is still not very good. The bitcoin: URI is a step
199 in the right direction, but need to work in most or every browser in
200 use. Also the bitcoin-qt client is too heavy to fire up to do a
201 quick transaction. I believe there are other clients available, but
202 have not tested them.

">BitCoin
</a

257 what properties the system have, and how it will be affected by laws
258 and regulations here in Norway. Here are some random notes.
</p

260 <p
>One interesting thing to note is that since the transactions are
261 verified using a peer to peer network, all details about a transaction
262 is known to everyone. This means that if a BitCoin address has been
263 published like I did with mine in my initial post about BitCoin, it is
264 possible for everyone to see how many BitCoins have been transfered to
265 that address. There is even a web service to look at the details for
266 all transactions. There I can see that my address

</A
>
272 of EFF have received
2447.38 BitCoins so far. Thank you to each and
273 every one of you that donated bitcoins to support my activity. The
274 fact that anyone can see how much money was transfered to a given
275 address make it more obvious why the BitCoin community recommend to
276 generate and hand out a new address for each transaction. I
'm told
277 there is no way to track which addresses belong to a given person or
278 organisation without the person or organisation revealing it
279 themselves, as Simon, EFF and I have done.
</p
>
281 <p
>In Norway, and in most other countries, there are laws and
282 regulations limiting how much money one can transfer across the border
283 without declaring it. There are money laundering, tax and accounting
284 laws and regulations I would expect to apply to the use of BitCoin.
285 If the Skolelinux foundation
286 (
<a href=
"http://linuxiskolen.no/slxdebianlabs/donations.html
">SLX
287 Debian Labs
</a
>) were to accept donations in BitCoin in addition to
288 normal bank transfers like EFF is doing, how should this be accounted?
289 Given that it is impossible to know if money can cross the border or
290 not, should everything or nothing be declared? What exchange rate
291 should be used when calculating taxes? Would receivers have to pay
292 income tax if the foundation were to pay Skolelinux contributors in
293 BitCoin? I have no idea, but it would be interesting to know.
</p
>
295 <p
>For a currency to be useful and successful, it must be trusted and
296 accepted by a lot of users. It must be possible to get easy access to
297 the currency (as a wage or using currency exchanges), and it must be
298 easy to spend it. At the moment BitCoin seem fairly easy to get
299 access to, but there are very few places to spend it. I am not really
300 a regular user of any of the vendor types currently accepting BitCoin,
301 so I wonder when my kind of shop would start accepting BitCoins. I
302 would like to buy electronics, travels and subway tickets, not herbs
303 and books. :) The currency is young, and this will improve over time
304 if it become popular, but I suspect regular banks will start to lobby
305 to get BitCoin declared illegal if it become popular. I
'm sure they
306 will claim it is helping fund terrorism and money laundering (which
307 probably would be true, as is any currency in existence), but I
308 believe the problems should be solved elsewhere and not by blaming
309 currencies.
</p
>
311 <p
>The process of creating new BitCoins is called mining, and it is
312 CPU intensive process that depend on a bit of luck as well (as one is
313 competing against all the other miners currently spending CPU cycles
314 to see which one get the next lump of cash). The
"winner
" get
50
315 BitCoin when this happen. Yesterday I came across the obvious way to
316 join forces to increase ones changes of getting at least some coins,
317 by coordinating the work on mining BitCoins across several machines
318 and people, and sharing the result if one is lucky and get the
50

321 if this sounds interesting. I have not had time to try to set up a
322 machine to participate there yet, but have seen that running on ones
323 own for a few days have not yield any BitCoins througth mining

350 some help from my friend to get it all running, and he even handed me
351 some bitcoins to get started. I even donated a few bitcoins to Simon
352 for helping me remember BitCoin.

>So, what is bitcoins, you probably wonder? It is a digital
355 crypto-currency, decentralised and handled using peer-to-peer
356 networks. It allows anonymous transactions and prohibits central
357 control over the transactions, making it impossible for governments
358 and companies alike to block donations and other transactions. The
359 source is free software, and while the key dependency wxWidgets
2.9
360 for the graphical user interface is missing in Debian, the command
361 line client builds just fine. Hopefully Jonas
362 <a href=
"http://bugs.debian.org/
578157">will get the package into
363 Debian
</a
> soon.

365 <p
>Bitcoins can be converted to other currencies, like USD and EUR.
366 There are
<a href=
"http://www.bitcoin.org/trade
">companies accepting
367 bitcoins
</a
> when selling services and goods, and there are even
368 currency
"stock
" markets where the exchange rate is decided. There
369 are not many users so far, but the concept seems promising. If you
370 want to get started and lack a friend with any bitcoins to spare,
372 <a href=

</a

0.05
373 bitcoin at the time of writing). Use

375 on the current exchange rates.
