Transcripts

welcome to this course

of blockchain today continuing in our

course

we will see about the history and

the future of blockchain we will be

talking about

that how did blockchain evolved and what

does the research suggest

us about the future of blockchain

blockchain as we have seen is a

buzzing technology a new technology but

actually the concepts on which the

blockchain is built

is not new today we'll be seeing

that how did blockchain came into the

picture and

what are the technologies which it is

using

when these technologies were first used

and how these technologies combined

together to make

this world blockchain and what

the future of blockchain lies so let's

see

a timestamp chart which will give us a

clear picture of

from the history to the future of

blockchain

as you can see over here we have

taken the timestamp from 1991 till 2022

the journey of blockchain from 1991 till

2018

is from blockchain 1.0 then blockchain

2.0

and currently we are living in an era of

blockchain

3.0 what the future lies in 2022

and in 2025 and then in 2030

is also present in this video if we go

back

that how did this blockchain evolve and

what were the banner technologies which

used the concept which was very much

similar which is used in

blockchain so history takes us back to

90s

so this is not something which is very

new which is to be afraid of

remember that it is an amalgamation of

things which was

already there so when we see further we

find

that in 1991

the first work of cryptographically

secured block was done

meaning the cryptographic technique was

used to make a secured block to store

the data

the first work of time stamp control was

done in 1991

by stuart harbour then as we move

forward what do we find is that in 1998

the first decentralized digital currency

was introduced by the name of bit gold

it was a decentralized digital currency

made by nick

says bow a computer scientist so this

digital currency

and a cryptographically block it came

long back in 1990s

so what was stopping blockchain how did

this blockchain came to the picture

we will very soon see to it

in 2000 this block

which we talked about that which came in

1991 and then there was a secured

currency also decentralized currency in

2000

first theoretical concept of

cryptography secured chain of block

means which we call a blockchain it is a

cryptographically secure chain of block

the first concept of psychographically

chain of block was given in 2000

by stephen konst so stephen konst was

the first person

who gave this key concept of

cryptographically secured

block in 2001. now

let's move forward and see

what happened in 2008 which is

considered to be a specific change

in the time of blockchain

having seen this journey from 1991 to

2000

which has already given the major

concept and which has already given the

secure chain of blocks

then what happened in 2008 which is

considered

as a remarkable change in 2008 satoshi

nakamoto

which is not actually actually the known

name

we do not know who is satoshi nakamoto

or whether it is a group of people or

not

but satoshi nakamoto released a paper in

2008

he started working on a concept and he

introduced a term which was known as

bitcoin so bitcoin was an application of

rock chain which was the first digital

cryptocurrency

and the first platform which was used

now why did it become so famous it

becomes so famous because

it solved the problem of double spending

there was a drastic change in financial

institutions

the financial market was going down

there was no trust among any financial

institution

and economy was facing a change in 2008

at the time it was a need of the r

to give something which could be trusted

and satoshi nakamoto

introduced the concept of bitcoin

and which prevented double spending

without

any interference of third party so let's

see

what happened in 2008 from the

time stem in 2008 satoshi nakamoto

introduced the concept of bitcoin

paper was published and in 2009

he officially released this blockchain

platform of 2009.

after the success of this platform of

2009

many more companies and many other

organizations started thinking in the

direction of blockchain

and started thinking in the direction of

cryptocurrencies

the main motive of satoshi nakamoto

bitcoin was not

application oriented it was only focused

on cryptocurrencies

in financial institutions to transfer

money from one party to another party

in the form of digital currency so

satoshi nakamoto was the first person

who collaborated this concept of

secured chain digital currency and

introduced this concept of bitcoin in

2008

which was officially launched in 2009

then in 2014 the

system changed from blockchain 1.0 to

blockchain 2.0

many new cryptocurrencies came into the

market like ripple

ether and there were many others

which came and the focus was still

on crypto currencies but work

shifted from cryptocurrencies to smart

contract

due to ethereum in 2013

ethereum was developed and in 2015

ethereum was finally launched by

virtuallynberrat

he finally launched ethereum in 2015

and the concept changed from bitcoin to

smart contract

from cryptocurrencies to smart contract

where

we could focus on other work through

these smart contract but still

the blockchain did not gain it based

many other cryptocurrencies came

to the picture and it was a boom in the

concept of blockchain

in 2014 so this gave a period of

blockchain 2.0

in 2015 a major project which is known

as an enterprise blockchain

hyper ledger an open source blockchain

project was

started by linux which allowed many

industries to focus on blockchain

project to contribute on blockchain

project

and to make an application oriented

blockchain

so an enterprise blockchain was

introduced in 2015 by a project

of linux called hyper ledger

in 2018 the complete picture

changed in 2018 the concept from

bitcoin smart contracts it's shifted to

application oriented that why can't

these a smart contract why can't this

platform of blockchain

be used for different applications in

different scenarios

wherever possible wherever trust is

required so in 2018

it gave birth to blockchain 3.0

so let's see what happened in blockchain

3.0

in 2018 the focus changed that

blockchain platforms ethereum

hyperledger

they can be used for different type of

applications whether it is health

whether it is supply chain whether it is

finance whether it is

medical lines whether it is government

records

land registries in everywhere where

there are different people which are

involved blockchain can be used so

blockchain 3.0

the era where we are currently living is

came in existence in 2013.

then if we talk about

the present scenario it is

believed that by 2020

we will be having a 10 billion dollar

of work of blockchain by 2022

there will be an industry of blockchain

using

10 billion dollars by 2025

the blockchain industry would be of 176

billion dollar and by 2030

that is approximately nine years from

here

the blockchain industry would be of 3.1

trillion dollar so friends blockchain is

an industry which is there to survive

these records of gartner research

already shows

that what is the future of blockchain

and we have also covered what is the

history of blockchain

how did blockchain evolve from 1991

how the bitcoin paper was introduced by

satoshi nakamoto

and how and shift to the scenario to

application

orientation so that's

for this video we'll be seeing more

about

bitcoin and blockchain and ethereum in

the coming video
