actually good evening everyone
so here we are here to fight
prejudice
nothing really bad so already
first prejudices that I’m going to stop
who knows this guy from the east who comes to us
talk about the dark web
rest assured all is well we will speak
of chain and bitcoin blocks under a beautiful
aspect the first aspect his clothes
the title of my intervention is
bitcoin blocks shine emancipation
digital
so actually the question is
this one
the agglo chain a little everyone has
heard recently especially if
you are a famous financial raptors
as we saw in intro you have
necessarily seen passing blocks
chain somewhere so I have you
made a little small selection of
newspaper headlines that we can have these
last time on the blogo channel for
we understand a little euphoria
general in which we are the
economists and therefore not a newspaper that
tends to do in caricature
seriously spoken of as the machine
has confidence that will revolutionize the
world on the platform in France which in
speak as of the most invention
important since the internet
just that you have two books in
issued 1 but there are plenty of others
who speaks to you about this as a
revolution that will change the world
money the business so there really
we are on the verge of comparing that
with the invention of the lightsaber fire
it’s like you want but overall
everyone agrees everyone
agrees it’s a revolution
problem nobody knows why
it’s annoying we’re going we’re in the process of
to live we will live a revolution but
nobody knows why and we come
often in a situation that is the
next I showed in the small
comic that has become quite iconic
in the community
you have a boss who will see his
developer who tells him we have to
build a block chain to
developers there have already been the
situation on intelligence
artificial on the big data on
internet of things etc
so he knows that according to his boss did
understood nothing to what he said so he
will ask him an absurd question for
check if the reason so we will him
ask what color do you want
your blog shane which pretty much
as much sense as if I ask you
but you prefer facebook salted or
sweet
it has none do not look and so
the boss does not demobilize and he
said bad move because it has more than
ram has more memory
so we’re really on a stadium
quite dramatic and why we are
got there because actually the joke
chain has become the solution but
usually when we talk about a
solution we have a big problem at
departure and in fact we forgot the
problem for me today I you
spoke chain and bitcoin blocks certainly
but not right now
first we’ll talk about the problem
initial that is resolved by quickly known
and the dear hangs and so if we talk
today from the initial problem we are going
talk about money
I usually do not have too much trouble
mobilize the crowds on this subject there
it interests everyone
everyone has more money or
the less we win, we lose all
days more or less also if I
you go out for example a ticket of 10
euros
what is money?
does that mean what does it mean
I have a value of 10 euros in the
this value of 10 euros
it has a value 10 euros why
because the traders accept it
because we all agree on the
makes it worth ten euros so by
example today with 10 euros I
can obtain goods and services in
exchange for example at current course I
can have sixty bread
chocolate 10 15 cents coin but
obviously this money from an exit in
my pocket
is that it really belongs to me there
that’s the question I’m asking is what
the very money you have in
bank accounts today there you
really belongs
obviously if you ask the question
it’s a bit oriented we will see that my
not necessarily and for that we will do
a little trip we will go to Cyprus
a beautiful island of cyprus island
heavenly a little over a million
inhabitants per capita between 25
and 30 thousand dollars a year so it’s okay
honorable numbers
it’s not the top of the basket but it’s
not dramatic and beats Cyprus has
a problem
hyper original really are the only ones
to have it is the public debt
no one else if this problem is
obviously the public debt of cyprus
and beats in 2.95 at 2006 2008
we are generally around 50% good
is not dramatic especially considering the
time running and then there is a
crisis for those who were in a
cave in 2008 there was a crisis enough
important that does in that has made that
to the Cypriot economy ended up
much more indebted than she
was it before and so in the space of
a few years we went from 50%
at 100% is more than 100% and therefore in 2013
little Cypriot crisis where the banks
Cypriots finds herself having to
repay money they did not
not so obviously big enough
problem but they have an idea of
genius you’re going to ask yourself why
they did not think earlier
these summaries in this little
illustration that I show right after
awesome guys we’ll be able to help ourselves
directly to bank accounts
great champagne that is it looks
to be a caricature but that’s
exactly what happened 1 so we
laughs 30 seconds and well done we get
said shit me too I have an account in
bank in cyprus 2013
banks that were in debt
are saying well we’ll take 10% off
all assets over 100 thousand
euros 1
why do not we have access so
this is it now why
she can do that because today
precisely your money and on
bank accounts and accounts
banking and what is it a
bank account today globally
it’s a series 2 0 and 2 1 everything is
digitized and therefore from the time
where it’s scanned you believe that
it’s your money
not really in reality it’s money
from the bank and then from time to time
wanted to ask for access to your money
and so it completely changes the
perspective so here we start already
a little bit to doubt
is that really what it’s my money
there are other examples I do not have all
do them but overall you take
greece took ukraine argentina
or india
two weeks ago was not there is
three years the two weeks india it’s
the government that says November 9
well we will demonetize 86% of the
currency in circulation
thank you you have until tomorrow
it’s not a joke it’s really
that happened
so what does that mean
that means that globally your
money it belongs to you no more
you have the answer to my question
why because we want everything to be
in accounts it’s the war of cash
who today still use the cash
as a means of primary payment in all
main case plus a lot of people and
that’s really noticeable
but it’s a bit of a danger and
it’s a trend that’s in there
badly of country we do not know that the countries in
development if you take the
bottles in the countries of the ocde are
generally much earlier
on it you take sweden is
usually the cantor of
social-liberalism of the north and its downs
Sweden 80% of purchases are made without
liquid
What does it mean
concretely it means that if
tomorrow you go to stockholm and that
you take a taxi a bus you have
in a small shop it’s not that
you will not use liquid that’s
he simply could refuse
not pay in cash in a taxi have
no equal london the same thing
I was there a few weeks ago
I’m going on a bus I ‘m going to buy a
cached ticket not possible to
solutions continue on foot or go out the
credit card and so I continued to
foot
so that’s a small problem then
obviously digitized the money that to
full more is not going to veil the face
we can we can thanks to it will avoid
to walk with three tons of
coins and notes in his pocket
we can pay the right amount directly
when you are at the cashier
it saves us from waiting ten minutes
to have the change either send
money all over the world and was
nothing to the full benefits but that to
some small inconveniences that we will
see right now but rest assured
three times nothing so first time
nothing the financial exclusion of the
half of the world’s population
it’s not much of course we’ve
tend to forget it because actually
in the countries ocde down everybody a
Bank account
overall we look around
everyone else is telling
usually it’s sometimes a
legal obligation but in waters
rest of the world and if we take the world
in all its 53% of people who
do not have a bank account and who have
access to any financial service
primary so it means 3.5
billion people is not nothing
all to all these people we go to them
to say very kindly we make war
cash
so sorry you can not use anymore
cash on the other hand do not hesitate to
go through this bank account on you
forbidden to open
it’s going to be very funny to go see
the South African farmer the farmer
Indian to go tell him no open your
bank account but you can not
second problem second time nothing
yes we can why because if the
bank she holds your money and
that’s what you do with
overall your privacy is
reduced to a small portion how 10
at 0
the bank is everything you do
she sells everything you buy everything
what you sell so you will have beautiful
try to hide it from all your
force the bank is that you buy
cds justin bieber and that’s what
is dramatic third time nothing a
intermediation which nobody wants me
explain to me you go to the bakery
today you pay two euros to
baker the baker he receives two
euros in cash very good thanks goodbye
you use the eba bank card you
it changes you nothing is even more
fast by the way you go out more
quickly from the bakery but he
it changes everything when it receives
no zorro life will receive 1 90 to 95
why is he human in the middle
do not see a guy called
payment service providers who
is called bank the establishment of
credit visa mastercard there are many
who are going to take a little commission
better and then he will not have his money
he will have it in 30 days 60
days or 90 days
never do we know so that’s a
third program that is enough
important if I told you that all these
little problems there three times nothing
so we could solve them by having
still the digitization of money
you see coming we come back on the subject
it’s bitcoin what does it avoid
that no I immediately I defuse
is not the money of the dark web I know
what etc
bitcoin we’ll go back to the drawing of
main definitions of its creator
it is a peer-to-peer
electronic cash system system is
digital cash rapper and
it’s very important is hiding money
digital liquid when one is not
sure of the online account we are not
sure of banking online we are not
sure credit card online on
digital cash
so that means all the
properties of cash got
open has decentralized its peers to
peers it’s without intermediary it’s
without borders it is resilience and
respectful of privacy etc etc
all quite quickly colleagues and with
bitcoin for the first time we arrive
to create numerical value a
digital value token ie
it’s not a debt title
it’s not a right of access on a
account someone has somewhere and
sometimes they give you access that’s
of numerical value and that’s it
important because they say value
digital okay very well
today what is the value
bitcoin digital bitcoins and 700
euros
[Music]
it’s okay that means I do not have a
bis
Corinne I have a little less than a mile
ceded tons visible until
millionth so no worries but that
makes a lot of money
what does it allow you to do
bitcoin in reality that allows you to
short circuit the system today
a transfer is like that it is to
to say that you are not giving a transfer to
someone you say to your bank
to send to the bank
usually there is a room of
compensation in the midfield but
I make it short to the other bank
who needs to warn your friend that he has
well received four days later your
money biscayne arrival you say no
no no you do not need all
these people there me I money your friend
receives it directly peer-to-peer
ten minutes
how does it work all that we fall
on our paws block her the joke
chain knows that abbas and nothing else
that the technology that will allow us
that will allow bitcoin obviously
I will not stop there I
detailed a little bit what is the
next
do you imagine thought experiment
imagine you a notebook until then all
okay
a notebook in which you will write
full full of transactions in
the occurrence all the transactions that
have been done in bitcoin so we
for example this notebook I write
obviously fictitious names have
nothing to do with the news
you have ras bruno that gives
nathalie tauziat who gives to nicolas
once it’s in this notebook and
well this notebook it is distributed
it’s curious because usually
we store some because having hall
locking do not want to be touched
not there if the notebook is distributed
everyone there everybody there all
the world can write on it so there
the two questions because with everything from
it is but if everyone can
write on it what a mess
that is happening
the second question is if he ever
there is a wrongdoer forgiveness if ever there is
a villain who arrive and who says
I’m going to erase a transaction where
I will add transactions
fraudulent how are we doing and there
your notebook you have to consider that it has
a validation system that is a
little bit particular
how’s it going on this notebook there
we are not going to validate transaction by
transaction in validate page by page and
it changes everything because you can
do periodic archiving
sequential every 10 minutes a
new page is added how are we going
choose what is this page in
reality we will let everyone
do what he wants with his page me I
for example imagine that we are at the
page 5 47
we want to go to page 48 all the
world in the network is in the process
to write his own page 48 with
transactions that received it even from
transactions which he is
the observer in the network who did
nothing to do with him he’ll do his
page is a consensus algorithm that
is called like that who will determine
randomly someone in the network
who will have the right to validate his page
what does it do once it is
designated he submits his page to the network
the network looks at it and says is that
all the transactions that are on it
are honest
yes no they all have the notebook so they
can trace all the history for
whether money spent does not
been spent before etc etc
and once it’s done we link the
page we go on after
what connection with the chain lock you
tell me there because for now we
is still in the experience of
think bah it’s very simple your
notebook it’s your blocking everything
simply the pages are blocks
and the binder is a chain the
pages are blocks the binding is
a voo channel digitize all that you
have a long chain a block with
transactions in it goes through
the consensus algorithm that I’m telling you
spoke the block this is your page it
is validated and then spread over the
network if you want to change anything that
it’s going to be complicated because
that you have to go modified on
everybody’s computer is so
there obviously I imagine a little of
disappointment because we sold you the
the most sophisticated technology of
world that will replace the fire the sword
laser and we end up with a notebook
Magic
obviously I understand your dismay
however under his airs a little puny
just introduced the only
ways that exist today
exchanged value on the internet
in peer-to-peer you will read
the operator already exists
certainly it existed torrent etc I
can you send a photo in torrent
very well we listed in reality I
you do not send this picture I create
a copy because I was always
access to the photo after I wanted
to send
so it does not matter when it comes
of a photo but if I resume my
ticket that I give you 10 euros it’s
quite important that I have more 10
euros after because otherwise it’s a
little the very principle of money that
is falling apart
so that we could not do before and
the chain block what is she going
do it will create the property
digital and trust in a
hostile environment without intermediary and
thanks to that you can change the
value on the internet then the value
it has been said that it can be currency
but it can be many others
things that can be titles of
share certificates etc. etc. so you
pay a small anthology of application
from the blog shane then y’a bitcoin on
saw it but I take you a case
very simple
the famous remmy rémy
discounts by donation cost of Filipino
who works in the united states that sends
money to his family etc
today does what they go through
western union western union that’s it
it takes him four days and it takes him
10%
good bitcoin ten minutes 5 cents for
maintain the network
from there the comparison
parties we move on
the certified way scribe
independent and peer-to-peer
decentralized beyond the property
transactive intellectual anti-flu has
renounced to new york
it is energy exchange in pairs
peer passed more by
the intermediary stored farewell the farms
of microsoft or google servers because
that you can do from the cloud
decentralized no one for
control your data I finish with
beats landes quickly for example
it’s in Ghana well we’re starting from
principle that we do not have very
trust in the Ghanaian government
to hold a cadastre so of the
list the properties
geographical of each and ben on va le
to get stuck there because we
does not need trust does not have
need of intermediary
so all that finally means
what does it mean that the chain blocks
has recovered control of its
data about his money on his life’s
general way and in fact I
finishes a little lyrical way but
what does it mean
say that for the first time since
for a very long time we are questioning
trust models that have existed
for centuries the banks the
notaries the governments etc
there we start to say effect finally
it may not be that useful
these people there for the first time in
the story one says to oneself I prefer to do
trust trust the notion is
very important to algorithms
rather than humans and there I you
ask the question is it really that
digital emancipation
thank you
[Applause]
