Blockchain, the future of money | Nicolas Cary | TEDxManchester


all right good afternoon I’m incredibly

excited to be here today I’ve had about

three transatlantic flights this week so

I’m glad you guys are caffeinated I’ll

try and maintain an even cadence in my

speech because when I get excited about

things sometimes I speak a little too

quickly about three years ago I started

a journey not too far away from here in

York and I’ve now flown over a million

miles around the world in pursuit of

answering a question which is what is

the future of money and I hope to share

with you a little bit about what I’ve

learned on that journey the last few

years and I submit that the future of

money may be upon us now technologies

like Bitcoin in its underlying framework

the blockchain we’re going to

fundamentally weave themselves into the

fabric of our society now these things

are exponential technologies and we

actually don’t experience exponential

growth that frequently and I mean that

in the way we experience the world but

let me provide a parable that kind of

helps me think about this imagine a lily

pond that in 30 days will be completely

covered by lily pads and today we plant

one and tomorrow it doubles in size and

then the next day there’s four and then

after that there’s eight does anyone

know what day the lily pond will be 50%

full it happens on the 29th day these

things are sneaky and they sneak up on

you so I’m 31 years old I’m a digital

native and I’ve only ever grown up

around technologies and I think it’s

kind of exciting to take a little trip

down memory lane to help us think about

how fast some of these changes are

happening so let’s take a look I

absolutely love photography so a lot of

the pictures you’re going to see in this

presentation we’re taken during my

travels over the past couple years now

this is kind of a fun one because ten

years ago the iPhone had not been

released yet okay so let that sink in

for just a second I used to have to

develop photography now that word is

extinct I can take a picture with my

smartphone I can broadcast it to all my

friends all over the world wherever they

are and instantly I can become a

photographer

I just have to do the same thing with

film and movies which is sort of funny I

used to drive my truck down to the store

and hope that they had the VHS or the

DVD that was available from a new

release but now at my fingertips on

nearly any device I can download any

piece of digital content I can watch

nearly any digitally release new movie

and I can get any song or any book

that’s ever been written in the history

of time I used to have to keep in touch

with my friends and loved ones by

writing messages to them and it’s a

little annoying when you travel

constantly and you forget your mother’s

birthday and this is a super risky thing

so now I’ve got a reminder in my

calendar and I send my mom a message and

usually some flowers too but think about

just how far we’ve come in the ability

to stay digitally connected so where

does this leave us well the digital

world is part of our DNA now it’s part

of how we share our experiences it’s

part of how we consume our entertainment

and it’s part of how we keep in touch

with our loved ones wherever they are

now I think it’s best not to have your

head stuck in the sand on this issue I

think money can be digital too now human

beings have optimized all kinds of

things it’s kind of what we’re really

really good at we used to live in caves

and then we build shelters we used to

walk around and then we invented the

wheel and we made roads and we’ve done

all kinds of things to make our lives a

little bit better

well we’ve also tried different forms of

money and this is a topic that should be

of real interest to people because a lot

of us will spend our entire lives in

pursuit of money I definitely encourage

you to do some saving too but the most

important aspect of this is that we’ve

optimized our money several times we

used to barter and then we created coins

and then we tried gold and we’ve tried

paper and now it may be time to think

about it in a slightly different way

what human beings need in order to

facilitate commerce

is actually a transaction network now we

interact with these every single day of

our lives whether it’s PayPal or

MasterCard or Visa or these other

systems let us move value around the

world and they all have three things in

common they have a currency that rides

on top of them they have a ledger system

that keeps track of who owns what and

then they have settlement with a high

degree of certainty those are the

ingredients you need to have a

transaction network function now a

simple

like sending money from here to a friend

should be really quick right its 2017

you know what’s crazy is this faster to

sending email from here to New York than

it is to send a hundred dollars to a

banks and all the intermediaries make it

very expensive and costly because they

have to run billions of dollars of

infrastructure just to do simple things

like send information around the world

what if there was a better way

well income a new technology called

blockchain technology and it was

pioneered by an open-source project

released in 2009 it has been running

without interruption for over eight

years now this is really interesting a

blockchain is basically like a big

spreadsheet in the cloud except instead

of there being one copy of this there

are actually copies of it all over the

world and every single one of them is in

exactly the same state all the time now

if there’s one thing you take away from

this conversation try and let this piece

settle in when an update happens on this

record-keeping system it is updated

globally and simultaneously there is

actually more compute power backing up

this network than all of Google and a

lot of people don’t know that but it’s

true now here’s what’s really really

cool about this once you have a

record-keeping system that is globally

distributed then that one single person

can alter or change you have a really

really exciting opportunity to reinvent

lots of new things and the first project

that’s been placed on this network is

money so maybe some of you will have

heard about a digital currency called

Bitcoin and it’s been in circulation now

for quite a while last year it was a

world best performing currency on earth

and there are some reasons for that but

here’s what’s really exciting anyone on

the planet can now download a piece of

software and instantly put it on their

phone that’s completely free and

open-source you can actually with ten

thousand lines of open-source software

code replace your bank now let that sink

in for a second anyone on earth

regardless of where they were born what

color their skin is what their credit

score looks like wherever they are can

now put an app on their phone and then

start to transact with anybody else on

the planet now this is going to start to

change an awful lot of things so if

you’ve never seen the digital currency

transaction do some research online and

check them out it’s pretty neat you

basically have an address you can share

with anybody and then they can make a

transaction with you it works

awful lot like email I can’t blindly

email somebody if I don’t know their

address but if I do then I can send them

a message and it’s the same thing with

digital currency when you make that

transaction it happens on a peer-to-peer

network there is no bank

there’s no forex market there’s no

intermediary it’s entirely between the

individuals that choose to participate

on this open network and when the

transaction happens it gets broadcast

that big spreadsheet in the sky and all

of the nodes in the network update

simultaneously everyone agrees that a

certain amount of value move from one

place to the next so why is this a

really big deal let’s talk a little bit

about this there are seven point seven

trillion dollars in credit card

transactions last year costing consumers

hundreds of billions of dollars in fees

every time you swipe your card they take

a little bit of that and they actually

charge you for it so all this is costing

us but it’s not just about credit cards

right where I was born in the United

States I just flew in from Bryant Park

in New York City yesterday I can tell

you kind of a sad story

there’s a pond there a little pool and I

was having an important meeting and

there was a poor homeless man going

through the pond picking up coins while

little children if we’re putting coins

in there and making dreams and their

wishes come true hopefully now this is

in the most prosperous powerful country

on earth and we have a world where you

have monuments to capitalism and people

that don’t have enough but it’s not just

obviously the first world right there

were 2.5 billion people on planet earth

that have zero access to financial

services whatsoever today so here’s

what’s kind of interesting about this

technology what if the parents of two

young Thai children had access to a

financial protocol that uses the

internet that actually allows them to be

more efficient than the hedge fund

managers in Canary Wharf now doesn’t

that start to get kind of interesting

all of this technology has been built by

an open source community from the top

trektop cryptographers and computer

scientists in the world and what’s

really neat about open innovation is it

invites everyone to come participate and

do code review and make the project

better so we actually have a way of

upgrading this system to make it faster

and more effective over time so what is

going to happen next is kind of the big

question everyone’s been asking

well every single year since 2009 this

network has quietly doubled in

transaction volume with more and more

people testing it and trying it year

after year so let’s remember about that

lilly pond for just a moment but once

you have that record-keeping system that

big spreadsheet in the cloud that

constantly agrees about what happened

and no central entity owns it well you

can do a lot more than just economic

transactions you can use it to store

reference information to things that you

own like assets like your house or

shares in a corporation or maybe

diamonds or precious artwork and there’s

a company working on that right now

actually there’s a lot of companies

working on that to use the blockchain to

keep track of all the property rights in

the world property rights are the very

basic need for capital formation if you

don’t have a house you can’t use it as

leverage to get a loan for other things

so if you’re an aspiring entrepreneur

you need to be thinking about some of

these things supply chains are kind of

interesting all over the world today we

put things in our bodies and we think

that maybe they’re organic or that

they’re sourced from the place that is

marketed to us from but there’s actually

a very little way to prove that that

happened well if there was a network

that was impossible to forge that could

track the origin of things like tuna

from c4 to fishing boat to

transportation to our plate and we could

verify the provenance of all those

things happening we could bring radical

transparency to the food we put on our

plates but too much more than that – I

think payment rails are really really

obvious ones all those people around the

world that now have a smartphone can now

participate and become harnessed by

economic activity on the Internet and

that is tremendously powerful so let’s

keep that in mind too but maybe one of

the most compelling reasons and when we

should think about the most right now is

a store of value so a lot of us last

year who hold pounds in our bounces saw

a depreciation of 17 percent when that

happens in a frontier in emerging market

you have headlines of collapse and

complete financial instability that

happened here and it wasn’t just here it

happened in Argentina in Venezuela

increase in green in Greece in Ukraine

in China why is the money devaluating

you have all kinds of experts to talk

about this but it’s pretty simple

if they keep making much much more of it

than everything that we own becomes

worth less and less and less in fact

it’s all designed to encourage you to

flip the money over spend an increase

the amount of monetary rapidity and

there’s some economists I think that’s a

really good idea I think there are some

that would argue that that’s not the

case and as a store of value imagine

being a person that was able to hold on

to a digital asset that you yourself are

the bearer of the custodian of and if

you could hedge against the global risk

or hedge against even the local risk of

a currency manipulation well that might

be something that would be important to

you so the most interesting thing if we

just spend a few minutes looking over

the horizon and if we all took out a 20

pound note today and looked at it we

might think it was kind of funny right

we’d have to explain who the picture of

the old person is and why it has all

those numbers on it and it’s kind of

dirty and it’s inconvenient to use for a

lot of transactions so what if that

actual note was a piece of information

that you could program to do other types

of things well this is where the future

gets really exciting imagine that your

refrigerator has a balance on it it’s

actually a smart device connected to the

internet and it knows what your budget

is for food this month and then when you

run out of the beers in your fridge it

actually dials up the local drone

delivery service that flies over to

Amazon that picks up a six-pack of beer

that flies it back and drops it off in

front of your house and then it goes off

and lands on your neighbor’s roof to

recharge on the solar panel that that

guy invested in and when that all

happens a geolocation ‘el trigger goes

off the refrigerator makes payments to

everybody and you have beer before you

get home if you don’t think that’s not

cool

well I don’t know but I’ve got other

ideas too but I think that world’s not

that far away ten years ago we didn’t

have an iPhone where will we be ten

years from now so whether you were born

in the first world or the third whether

you are running a for-profit or a

non-profit whether you’re a parent

sending funds home to a daughter or a

child sending remittances back home to

your parents

I believe this technology that’s built

an open protocol that’s fair that’s

accessible to all is going to

dramatically change the way we think

about the tools that we use on

especially in the way we interact with

each other economically so I think and

submit to you that it’s time to

reimagine money so thank you very much for your time today
