Bitcoin – A moeda na era digital | Fernando Ulrich | TEDxUFU


everyone home is a huge pleasure here one

show events and I talk a little

the subject may be slightly different

democratization but this time

the democratization of money

in 2008 the world witnessed the beginning of

two major monetary experiments

but in common these experiments have

only the start date because it does not

could be more distinct one is

Coercive is both voluntary

in these experiments is led by this

group of people

these are the most important central bankers.

of the planet are the owners of the

coin printers

reserve as dollar the euro and in oil

and those injuries that are supported by

almost all economists of most

of economists

Only the experiment a little bit

different because the participants in this

experiment has no alternative are

obliged to participate as if they were

guinea pigs but this experiment is not

I want to talk because from here, nothing.

good

The experiment will not end, I do not want to talk.

is this was created by an individual a

complete anonymity and highly influenced

sai culture was punk from the 90s and

was an experiment that started without

no funding without any support

formal center economist

academic degree from a university or

support of any edition and today

is the computer project

distributed more potent planet

whole away from second place but

before we go a little deeper

of context

everybody is tired knowing

telecommunications revolution

from the invention of the

telegraph in the 19th century that

internet internet Victorian era

after the phone with radio tv

computer the personal computer

mobile phones and after creating the

growth was simply

exponential and scary

today any of you with a

simple mobile phone with a simple

but phone connected to the internet you

they can create a youtube channel by

example and compete until the

television network and that’s enough for a

mobile phone and an internet connection you

can share text photos tweets the

that is

all at almost negligible cost

instantly available for the

hunter globe

but if you try to pay someone

or paid to try to pay

someone as easily as yes

a medium there you can not get there

it will not be possible because this

because this state of affairs

one of the reasons is that it is the

financial system and the

monetary policy are incredibly closed and

anachronistic

if someone tries to send a boredom today

today in lion asks for a dock for any

person will pay about 10 reais and 10

to send a simple request if

You try to send money out.

from the country

there will be more expensive still about 50

dollars will take days and this if not

there is no error in the message that

a space plus one space – ours

money stays in limbo for weeks

who does not know where the money goes

stop never had this experience know

which is the most unpleasant things

can spend with someone trying to do

an international payment because this

because it is so complicated to use the

money in the digital age

if money is nothing more than it is

Our game on the bench is nothing more than

mere electronic digits

why is it so difficult to have a book

from one side to the other because

It needs to take days.

it is as if the financial industry does not

had suffered from all the advances

technologies that we have today because

It is true that our financial system

banking eliete frame to the world

modern

one reason is that unlike

digital files that can be

reproduced infinitely the money of

can not be played back because if this

happen it will be related and will

lose buying power quickly

so we need to make sure that

when we transfer when our

electronic digital exits the account

I’m sure it really comes out of the

account will stop in the account of who was

the national

if this happens we could spend

once again the same coin the same

digital money

and to deal with this issue called

of spending double the banks spent much

money with infra banking structure

with security to maintain a system

without fraud and with great security for

the participants

another reason is that we live today

up in the so-called coin era

state

today is our money the money

state owned by the government itself

and because of that we have a

artificial creation a barrier

artificial man – made called

border for those who do not know this one

It is the border of Brazil with Uruguay.

in the number of the south country that is of the city

Santana of deliverance and the right is

city ​​of rivera if you imagine

Brazilian in Uruguay trying to

transact here in the middle of the street

we won with a paper in kind to

rigor would be an international attraction

a cell of two parts will go

Being an intermediary, no problem.

now if they try to do this

transaction using the banking system

will have to send in the

time of payment from your bank the bank

she lives on the bank’s payment

correspondent who will convert the

dollars to send

payments from the corresponding bank of the

across the border and will convert

the dollars in pesos that will send a

payment to banks subject to sending

Money if you read it does not make sense to it.

It makes no sense

imagine when you can send one and

mail appears on the phone screen

the question crs means pro brazil too

It costs so much to email goes to

even though it is 50 reais and will

take a few days

Ana but today is Saturday 26 does not work

Do not know on Sunday?

[Music]

You can not imagine that really is.

interested but the fifth test

the rest is the current paradigm for

currency for money for the system

financially that people live but is

changing is fast changing

thanks to a technology called beach

boy bug is technological invention

most fascinating

I would say that it is more important since

version since the invention of the internet

It was a digital currency but it is much more

than just a digital currency because

it is also a system of payments

without borders does not depend on

no central bank of any government

of no bank and runs a network

fully decentralized

This really never ever made us

something like something actually

revolutionary and an idea somewhat

subversive that money parallel a

money that does not depend on the government

we understand better how to

In fact, the system must first

How does it work today?

we were just going to find the person who

we want to relate to the fans of

payment between two parties does not

no intermediary and payment is

regressive then we pay a

person passed away with her money

she is good she has no one to turn to and

try to reverse that payment as well

it is not necessary to know the parts of the

when we go to the newsstand

buy a magazine and half you know

we do not need to know the identity but

if we do with the equipment and

we send larger or longer sums

distances

we can not escape a

the payment system you know best

nowadays it is the banks themselves

There are payment systems such as

paypal is a payment system for the

online environment

but today’s paradigm is state currency

on the one hand and payment systems for

other the idea as bystroy

paradoxically is to replicate these

properties of the physical money of the

money kind payment without

intermediates

one does not need to know the identities of

people relate and reversible to

replicate these properties in the environment

digital

only when something extraordinary happens

occurs because we have not only a

payment system, not just a

currency but their payments also

two things at the same time and this is a

of the great innovations of the beach boy toy

just a cell phone connected to the

internet in questions of seconds you

the possibility of transacting with

any person anywhere in the world.

confiscated from the blocked anyone

try to prevent you from parking or

then inflate your digital currency

corrupting her purchasing power is

really revolutionary and subversive

a technology like the one that created it is

Who had this crazy idea?

and out of the box

at the height of the financial crisis in 2008 was

I did not tube a guy named satoshi nakamoto.

posted a message from a message

to a list of topography online where

he said he was creating a system

electronic money by the spirit and

in this message he attached a paper where

nine pages he writes how

system would work

this was in October 2008 three months

then he made available a system

for anyone who wants to start downloading and

to build b’s network was in January

in 2009 the limit was the first currency

that is said to be centralized is the

first decentralized digital currency

because it is said that the first

outdated because other attempts

make a digital currency in the past

always end up having the same problem

when they gave him the question of the

another that is the people’s expense resume

imagine that the ice edict is nothing more

than a computer file that

he was a pretty ex person

advance attach the file in the message

sent to you know that when people

attach a file in the middle for example the

original file is deleted computer

make and attach this same file ia

to another person is fully possible

is filed digital money we

I could spend that money twice

and be a problem to deal with this

question of double spending and other

attempts to make a digital currency

always employed a third party

confidence in the centralized entity

responsible for the validation of the

accounts to ensure that there was no

fraud and also responsible for

digital currency issue

the video was obtained was the first to

able to solve this problem in the

our double in a decentralized way

no central entity does not exist

there is no business

responsible for the beach boy at the beginning

an owner of this system is a protocol of

communication as well as the

communication protocols on the internet

tcp / ip not say that an owner

cause much perplexity

because it is a safety model that

it is the inverse of what we know

and the first question that comes to mind

as they do not have a good control who

controls have no one making

There is no one there.

individually responsible for this

which is when the safety of the

system that emits currency

What is the loop in that big coin?

I was able to delegate from Mexico

this task that until today has been

centralized for multiple users

volunteers who ensure all

days

dedicating computational power to the network

making evaluation of actions and

ensuring that there is no fraud

and no currency inflation and that is

this is a paradigm shift because

instead of time only one entity

only against a system where

nobody knows what ‘s going on

with him the goal is to reverse this

security model where the

transactions are all completely

transparent but no one knows who

is relating and all users

are constantly monitoring

inspecting and auditing that occurs in the

system is the new security model

I know that for a lot of people this collides

she suspects but it’s a

system that has been in use for

almost eight years and never had any

fraud

The accounting book has never been corrupted.

is called a block where

all transactions are there

registered a system like this with

so many characteristic features

different is and trade out of the box

in some rather subversive

it has several implications for

example, the first is that yes and

destroy is the first alternative

of a private currency that does not

because the state that this will grant

a license can not regret the

Private call child can compete

with people like he knows the government

does not like competition

especially in the monetary area

monopoly currency of the state but admits

that exists not because the government has

mita that it exists but because it is

impossible for the beach park

the goal is to build a network

fully decentralized as well as the

bit torrent network that you should already

have known heard until used

without knowing it has a network for

digital file sharing

uses the same network architecture

this means that it is impossible for

the team that does not have who will be the ceará

there’s no one who does not have an address

where you can send a

with a warrant

of security 19 in saw activities

it’s over the joke

there’s more there ‘s no way to do this and

Because of this, it was also a

competition to the banking system

the international shipping company as

the western union or the entities

to provide the messaging service in

international terms between swift banks

is a competition to this whole system

because the offense is committed not

need to use this system uses a network

parallel to the financial system

traditional

but it’s all cool that this new

technology is much more than just

money money is the first

application technology are still

technology that is a win because

football is actually a platform

for informational financial innovation

open to all and without any

need to ask me for any

and nowadays there are companies

like nasdaq that the stock exchange of companies of

technology from the United States that is

using beach boys technology

not because she is interested in

currency in digital money

but rather you can use it to record

other digital information such as

example doing trading of assets of

stocks and bonds debt register

real estate owned by the government

de honduras has a pilot project to

do this or use the beach network

boy to register documents for

location there is not a kind of

digital registry because another

innovations of victory is that it has

all transactions that occur in the

network are recorded a large file

digital your bitcoin ledger

called the box tim and this book

accounting is shared it is

unique and is maintained by all

users on the network and keep

Always updated with new

sanctions to the extent that it does not

occurring

and it’s a file nowadays so

computationally robust

feasible to forge audi and

corrupt that when it was once a

information on it is almost as if it

was immutable

A few hours a few days is impossible.

remove this information from there it

has value

it has a lot of value on June 17

this year on Friday at 7 pm

but me and my daughter and how was the sixth?

seven o’clock in the evening the offices were

closed and I as good enthusiast

technology is good, I’m going to register

my daughter in box tim bishop the record

she no system hla clerk tuesday

Last night her name was alice coimbra

the laugh June 17 , 2016

and this information is there until today

There’s no way that anyone can pay.

there for posterity

this is just an example of what can

be done with this technology

and to finish I want to leave a reflection

with two questions here for you

I got a technology and inclusive

financially inclusive

So what happens when we

boat billions of people

debts and a financial system

really international

the number of people in Brazil only

in Brazil that do not have bank access

it’s amazing

almost half of the people in Brazil do not

have access to the bank account or

basic financial services

What is the transformative potential is a

technology such as this that a

mobile phone and internet access and

without competition and innovation with 100

actually permitted under the currency and

I ‘m not talking about license here

authorization to renew the authorization

is really talking about

Revolutionary innovation is disruptive

if it really had an environment of

innovation and freedom to innovate in the

currency scope

Would we have a better currency?

a worse currency will be who would be

currency more or less inflationary

perhaps would be a form of currency

that we can predict a lot

superior to what we have today

Is it the kind of system that

We are in need thanks

for the attention

[Applause]
