Stephan Murph: !hat i/ ou could live in a 3itcoin intentional communit#
"here ou are livin$ amon$st people "ho ou ma3e 2no" /rom the Bitcoin
/orums# "ho ou 3u and sell 3itcoins "ith ever da< ou can $o to 3usinesses
around ou that accept Bitcoin# and ou can $et a *o3 that pas ou in Bitcoin. +s
that somethin$ ou0d 3e interested in doin$=
Andreas M. Antonopolous: + thin2 that "e0re increasin$l livin$ in a "orld "ithout
3orders that actuall matter so much anmore. + mean# it0s di//icult to travel# 3ut
once ou $et to places# it matters a lot less. + spea2 /rom an outsider0s
perspective 3ecause + don0t travel unless + a3solutel have to mostl it0s 3een
*ust to spea2 at these con/erences 3ut the concept o/ a$orism and 3
>a$orism?# essentiall + mean participatin$ in sstems that our outside o/ the
normal /lo" o/ commercce# li2e these intentional communities i/ the intentional
communit has an econom unto itsel/# and people do 3usiness "ith each other
in this communit# then that is a /orm o/ a$orism# 3ecause ou0re 3passin$ "hat
"ould 3e the standard methods /or doin$ that same tpe o/ 3usiness.
Bitcoin is such an interestin$ currenc 3ecause it levera$es the $lo3al# on the one
side# 3ut it0s also ver much a3out the local and especiall once ou $et do"n
to the phsical 3itcoins# li2e "e "ere tal2in$ a3out a couple o/ episodes a$o# +
thin2 that the chances /or doin$ somethin$ li2e this# and et havin$ all o/ the
advanta$es that Bitcoin o//ers in the $lo3al sense# are reall interestin$.
S.M.: Bitcoin is decreasin$ the importance o/ 3orders# ri$ht= Li2e# ou can send
Bitcoin all over the "orld# 3ut i/ ou "anna $et a ham3ur$er and ou "anna pa
/or it "ith 3itcoins# ou reall have to have people around ou "ho are "illin$ to
help ou /acilitate that 2ind o/ transaction. So + can see the value o/ intentionalcommunities# and reall *ust livin$ "ith people "ho are more li2e-minded# and i/
Bitcoin is reall important to ou li2e# ou mi$ht "ant to 3e around people "ho
share our love o/ Bitcoin# and the other ideas that sometimes $o alon$ "ith
people "ho love Bitcoin.
!e see some o/ these intentional communities comin$ up< i/ ou $o to Berlin or
some other parts o/ erman# there are "hole nei$h3ourhoods "here all these
3usinesses accept Bitcoin# and o/ course Ar$entina0s 3ecomin$ reall 3i$# and
certain places in the 8S... + mean# all over the place# there are these Bitcoin
hotspots that are poppin$ up. !e0ve 3een invited to several Bitcoin con/erences
since Bitcoin 3e$an# 3ut no" the0re 3ecomin$ "orld"ide. Li2e# Ar$entina# 9apan#
@n$land# Austria... ever"here has a Bitcoin con/erence# and it0s impossi3le to $o
to all o/ them oh# Manila in the Phillippines there0s *ust so man o/ them
(laughs) and it can 3e a /ull time *o3 *ettin$ around the "orld to $o to all these
Bitcoin con/erences. + thin2 it0s a positive si$n to see them poppin$ up all over
the place# 0cause some people *ust "ant local interaction# and the0re not al"as
$onna $o to the hotspots to 3e a3le to $et that.
A.A.: + spent a3out a decade *ettin$ around the "orld# spea2in$ at con/erences /or
technolo$# and + a3solutel loved doin$ that# meetin$ people apart /rom the
con/erences# "e0ve also had this rich tradition o/ intentional communities# "hiche6ist 3oth in the cipherpun2 - as "ell as the c3erpun2 and hac2er - communities

"ith places li2e the Chaos Computer Clu3# and 5oise3rid$e here in San rancisco#
so there0s also this con/luence o/ Bitcoin and other communities that are comin$
to$ether< *ust li2e our Porcest Li3ertarian $roups up in 5e" Hampshire# here in
San rancisco there0s 5oise3rid$e and thin$s li2e that# and in erman# the
Chaos Computer Clu3. + thin2 there0s a lot o/ overlappin$ communities# and + "ant
to visit all o/ them# so + "ill happil pac2 m 3a$s and visit an con/erence "herepeople are "illin$ to pa m /ares to $et me to spea2 "ith $reat *o
A.L.: And there are a couple o/ other con/erences# too# there are t"o scheduled
/or Canada one in ;cto3er# and then another one a/ter the /irst o/ the ear. 1his
mornin$ + spo2e "ith the /ol2s /rom 3ehind the Bitcoin Cprus Pro*ect# actuall#
and the0re $ettin$ read to put on a con/erence in 5icosia that0ll pro3a3l also
3e ne6t ear. So the con/erence scene has a3solutel e6ploded "e "ent /rom
one a ear# t"o ears a$o# and then "e started havin$ a couple a ear# and no"
there0s literall at least one ever month throu$h March o/ ne6t ear that + 2no"
a3out# and "e0re still hearin$ a3out more on (nearl) a "ee2l 3asis. So on theone hand# it0s $reat that all these con/erences are happenin$# 3ut on the other
hand + "onder i/ people are $onna $et 2ind o/ 3urnt out 3 them# 3ecause there
are *ust so man.
A.A.: + don0t thin2 so.
S.M.: eah# + don0t thin2 so either + mean# the e6ist 3ecause people are super
e6cited and# ou 2no"# some3od "ho0s 9apanese doesn0t necessaril "ant to $o
to Canada to attend a Bitcoin con/erence the "ant to 3e a3le to $o to 1o2o. +
thin2 that ma2es sense< "hat "e mi$ht see is a little 3it more o/ a >splittin$ up?
o/ the Bitcoin communit - people are more li2el to $o to a con/erence that0smore local to them# and so as a result# ma3e the "on0t meet the people that
live hal/"a across the "orld - 3ut as the communit $ro"s# ma3e that0s the
direction it0s naturall $onna $o in an"a.
A.A.: + thin2 "e also have to consider the /act that the $eneral purpose
technolo$ con/erences thin$s li2e +nterop and SA /or securit and various
other con/erences involved in teechnolo$ies and telecommunications and
pament sstems have not et started havin$ dedicated Bitcoin trac2s or
dedicated technolo$ sho"cases around Bitcoin# and Bitcoin presentations. Ma2e
no mista2e a3out it: "e0re $oin$ to 3e in SA# at the con/erences# tal2in$ a3out
Bitcoin0s securit# and "e0re $oin$ to 3e at the technolo$ con/erences
demonstratin$ Bitcoin hard"are. So "e0re $onna start seei$ Bitcoin also "ithin
the conte6t o/ other technolo$ and $eneral con/erences.
A.L.: So one o/ the other thin$s that "e do here at Let0s 1al2 Bitcoin is "e
inter/ace "ith reporters "ho are /rom outside o/ the Bitcoin space# and *ournalists
"ho are outside o/ the Bitcoin space# and are loo2in$ /or e6pertise so that the
can e6plain this complicated issue to their audience# "ho has even less conte6t
to understand it than the did and it0s 3een interestin$ to "atch ho" the
various pu3lications have morphed over time in terms o/ their approach. A couple
o/ months a$o# there "as a 3i$ rush C5BC# and BBC# and a couple o/ other vermainstream pu3lications the "ere incredi3l concerned a3out it 3ein$ a PonDi#

and immediatel /rom moment E%# "hen "e $ot on the phone and started
tal2in$ to them# the vi3e + "as $ettin$ /rom them "as that the /elt li2e + "as
trin$ to sell them somethin$# and trin$ to $et them to put their reputation
3ehind somethin$ Fthat "asG $onna 3e a 3i$ scam# that + "as $onna ma2e a
3unch o/ mone o// o/ it and that reall has $one a"a. +ncreasin$l over the
last# ma3e# t"o months# the reporters have 3een $enuinel interested in trin$to understand ho" the sstem "or2s and "h it0s somethin$ that their readers
and listeners should appreciate. So that0s 3een a reall interestin$ chan$e to see.
1he /lipside o/ that# o/ course# is that a lot o/ them still reall don0t understand it
ou tr to use analo$ies that people can relate to< one o/ the $ood ones /or
descri3in$ ho" Bitcoin as a protocol "or2s relative to Bitcoin as a compan
"hich# o/ course# it "hat most *ournalists thin2 it is is to tal2 a3out 5apster and
Bittorrent# 3ecause 5apster "as 3asicall a centraliDed version o/ Bittorrent# and
Bittorrent is# o/ course# no" the most commonl used protocol /or sharin$ media
/iles on the "e3# i/ +0m not mista2en. +t has no structure# in much the same "athat Bitcoin is a protocol# a set o/ rules that one opts into# rather than 3ein$
somethin$ "here the have o//ices and have revenue and can 3e shut do"n.
So# the pro3lem# o/ course# is that then the "ind up comparin$ it to 5apster#
3ecause their readers 2no" a3out 5apster# 3ut the don0t 2no" a3out Bittorrentnovice user?. 1he Mac is ver popular# especiall in 5orth America#

pro3lem is that the don0t reall re/lect all o/ the Mac user inter/ace $uidelines
and all that# and "e *ust sa" that as an opportunit# as a startin$ point. But
certainl# i/ there is an opportunit to 3uild Hive# speci/icall# /or FotherG
plat/orms# then "e0ll loo2 into it# 3ut the /irst step is to see ho" this $oes# "ith

3usiness module +0m curious# ho" are ou plannin$ to monetiDe this=
!.: Actuall# +0ll caveat this 3 sain$ + 3elieve this0ll 3e some"hat controversial inthe Bitcoin communit# 3ut our /irst idea "as that "e "ould 3e a3le to actuall
ta2e transaction /ees /rom the activit that happens "ithin applications. + "ill
admit to ou that all o/ the details ri$ht no" "e0re still "or2in$ all that out# ho"
that "ould 3e done# especiall since "e don0t "ant to centraliDe that0s one o/
our mantras# to 2eep this ver ver decentraliDed. So "e0re loo2in$ at that# and +
don0t 2no" that that0s necessaril "hat0s $onna 3e the end$ame /or us# 3ut it0s
"hat "e0re $onna 3e trin$ ri$ht no". 1he other possi3ilities that e6ist "ithin this#
o/ course# are i/ "e $et some traction "ith it "e can do man other thin$s. But
/or no"# this is 2ind o/ "here "e0re at "ith 3aseline.
A.L.: !ell# that0s certainl an innovative model + don0t thin2 "e0ve heard o/

"hat tpe o/ level "ould these transaction /ees# i/ that0s the "a that ou $us

small percenta$e-3ased thin$# or "ould it 3e /lat and ver ver small# li2e the
transaction /ees are no"# or ma3e it0s .'''=
!.: !e thin2 that# pro3a3l# a percenta$e-3ased model "here it0s a tin
percenta$e is "hat "e0ll end up pursuin$. Havin$ said FthatG# + have reall no idea
"hat0s $oin$ to 3e accepta3le to the communit# and + hope that "e "ill end up
actuall "or2in$ "ith the communit to /i$ure that out. 1his is $oin$ to 3e anopen-source pro*ect# so + am actuall $oin$ to 3e completel transparent a3out
all that 2ind o/ stu//# and + reall "ould li2e to hear /rom other people a3out "hat
e6actl it is that the thin2 "ould 3e /air< "hat e6actl it is that the "ould li2e to

it0s Bitcoin# so it0s all ver open# and it0s all in/inite possi3ilit as /ar as +0m
concerned.
A.L.: + understand "h some pro*ects approach this /rom an open-source
perspective# 3ut +0m a little 3it surprised that ou0re approachin$ it# $iven the
model ou0re trin$ to pursue# 3ecause it seems li2e the natural ne6t step a/ter
ou0ve done "hat ou0re proposin$ to do here is /or someone to /or2 it# as ou
said# and then ta2e o// the /ees and sa >here0s the version /or /ree?. And there0s
nothin$ actuall stoppin$ anone /rom doin$ that in this situation.
!.: eah# that0s completel true< people could actuall /or2 this application
someone could ta2e it# and remove the /ees# and have the /ree version# 3ut m
assumption is that there is enou$h $ood"ill in the Bitcoin communit to
understand especiall i/ "e0re transparent a3out it that this is ho" "e0re $oin$
to ma2e our mone< that i/ ou do end up $ettin$ the version that actuall has no
/ees# then ou do mana$e to $et around the small /ees# 3ut "e also hope that the
/ees "ill 3e small enou$h that it0s trivial and that people "ill "ant to support this.

A.A.: !ell# map it out= 5o# 3ecause it0s a ver lar$e curve# mappin$ it out is not
possi3le. Ho"ever# the idea o/ a "ea2 curve is 3asicall that the curve itsel/ has
some characteristic that can 3e e6ploited in order to arrive at a mathematical
solution that is less hard than the 3rute/orce solution# so i/ it too2 ou a

to doin$ this in less than 3rute /orce that0s a "ea2 curve.
S.M.: + have a 7uestion that0s related to this. +0ve heard that 3ecause o/ these

A.A.: SSL "as not secure a$ainst the 5SA. + thin2 that0s important to understand#
