All of you welcome back to yet another

project video. In this project, you're

going to build your first ever own

private blockchain where you can able to

perform all the transaction. You will

learn how you can integrate your private

blockchain with the metamas and perform

the transaction and you will have your

own block explorer where you can able to

see all the transaction mine the

cryptocurrency see the data and transfer

the token and create your wallet. So let

me give you a complete walkthrough of

all the feature and functionality we

have included in our own private

blockchain. This is our block explorer

where you can able to monitor all the

transactions, send cryptocurrency, mine

block and see the transaction details.

So when the user will come there, they

will find all the details. So the very

first section we have our header section

we have called private blockchain. You

can see this is the currently running

API which connected with our blockchain

and fetching the data based on the event

model we have designed in our

blockchain. So here we have multiple tab

for overview wallet transaction mining

and block explorer. Here you will find

the overall stats about the blockchain

height pending transaction difficulty

and mining reward. So when the user will

mine the transaction we're going to

reward them 100 cryptocurrency. You will

find the pending reward is currently

active and here you will find the stats.

Blockchain is activated. This is our API

endpoint and we are following proof of

work model. So that's the overview. Now

let's come back to the wallet section

and here you will find your details. So

if you want to check the balance of your

wallet, you can check that. If you want

to create your new wallet, you can

create and you can start using straight

away on this particular private

blockchain. If you want to perform

transaction, then you can come back to

the transaction section. And here you

can able to transfer the fund. You can

see the details about the gas. Paste

your address where you want to send that

amount and your private key and you can

perform the transaction. Right now this

particular transaction is in the

pending. Someone need to mine this

transaction. So it will be executed.

Come back to the mining section and from

here you can able to mine the block and

when you will mine it you're going to

have a reward. Come back to the block

explorer. There you will find all the

transaction which we are getting on our

private blockchain. So you can able to

monitor the time, the block, the

transaction, the hash that's all you can

able to find. So right now you can see

here we have the overall. So let me mine

this particular transaction. So I can

simply come back here. I can give my

wault address where you want to receive

the fund. So I can click on this start

mining. And here you will find that I

have mined this particular blocks

successfully. And you can come back to

the overview and you will find the

transaction is mined successful. This is

the one way of performing and doing the

mining. But we have also automated

mining system. So when someone will

perform the transaction from the

metamas, the mining will happen

automatically and the user who's

performing the transaction will be used

as a minor. So that's the general model

we follow on a private blockchain. So

right now this is what we have on the

overview. Now let's come back to the

wallet and you will find that this is

the wallet generated section. So if I

want to create a new wallet, I can click

here and it will be created a new

wallet. I can copy the private key and I

can import in my MetaMask. If I want to

check the fund of any account, I can do

that. I can simply give the address and

I can give the check fund and it's going

to tell me how much fund is available in

my wallet. If I want to see the wallet

of this one, I can give the address and

paste and click on this check and you

will find that I have a zero fund in

this. In the same way, I can able to

perform the transaction. So, I can

simply copy this particular address and

I can use this one. So I can simply give

the address and click on this mine block

and it will used as a minor and if I

come back to the wallet if I check the

balance you will find that I have the

100 coins which I have got because I

have used this wallet as a mining

and that's what we are providing. We are

providing 100 reward when the user will

mine any particular block. If you want

to perform the transaction, you can use

this transaction model we have included

in the block explorer or you can able to

perform the transaction through your

Metamas wallet. I'll show you both the

transaction. So first thing what I will

do, I'll come back here, open up my

Metamas and I'm going to use my account

number four. So right now you can see in

my account number one I don't have any

fund but I can have fund on my account

number four. So I can click on this

account number four and you will find

that I have this much fund available in

my account number four. So I'm going to

use this account for mining the

transaction. So let me provide the

address. So I can simply come back here

and I can copy the address. Copy the

address and that's what I'm going to

provide here. Now I have to give the

address where I want to do this

transfer. I can simply come back here.

Come here. Go back to the account number

one. Then I have to do the transfer.

I'll simply copy and that's what I will

provide here. I want to transfer let's

say 333

333 and now I have to paste the private

key of my wallet which I want to use for

performing the transaction. So this

account private key I have to paste. So

let me quickly get it. So I got the

private key. I can simply paste and you

will find that I got my private key. Now

I'll simply click on this send and you

will find the transaction is executed

successfully. Now it's in the pending

and this pending will be only visible

when you are doing the transaction

manually from this block explorer but

when you will do the transaction from

the metabas it will have a auto minting

auto mining system and that's what we

follow on the private blockchain so this

is what I got it now I can do one thing

I can come back to the mine and I can

simply paste the address of any wallet

and I can simply mine this particular

block so I can simply come back here go

back to to the address to account number

four and I click on this address and now

I can copy that one and I can simply

click on this and click on this start

mining and you will find the transaction

is completed. If you come back here it's

gone. So we have successfully mined the

block and if you come back to the block

floor then you will find the transaction

detail. So this particular mining the

pending mining will only happen when you

are performing the transaction through

the private blockchain. But when you are

doing with the help of the metamas we

have attached a trigger model which will

automatically mine the transaction. So

every single thing is working fine. I

hope you have understood that this is

the private blockchain we have. And if

you want to check your front balance you

can click here and you can see how much

fund you have got. Now let's try to

perform the transaction with our

metamas. So I'm on the account number

four and I have this much fund. If I go

back to my account number one, you will

find that I got this much fund. The fund

we have transferred. So it's taking a

little bit time for getting here and

finally we got it. So if I want to

transfer more token to my account number

one or if I want to transfer from my

account number two other account, I can

do that. I can simply come back here,

click here and I want to transfer the

fund to account number four and I want

to transfer let's say 2002.

That's what I want transfer. I can click

on this continue and the transaction is

happening. You can see the log. Click on

confirm. And here you will find it's in

the pending. I'll click on this close.

And here you are getting pending. Simply

avoid this one. Now you can come back

here and you will find the token is

going to be transferred soon. So it

might takes a little bit time or if you

want to double check you can come back

here. Go back to account number four and

there you will find that this will go

up. So we have automated transfer model

automated mining system we have

included. So every single thing is

working fine. Now let me take you that

how the transaction model is happening

in our private blockchain and here you

will find that all the transaction we

are performing that's all we are getting

right up here. So first we have started

our private blockchain and there you

will find all the mining models we have

called all the data transfer we have

done that's all is getting stored on the

blockchain in our private blockchain.

This is the front end which is executed

and it's connected with our private

blockchain. So whenever I will change

the account, it will trigger the event

and it will fetch the balance of that

particular account. So this is the one I

have. So I'll come back here and if I go

back to my metamas, if I change my

account, so the moment I will change to

account number one, it will reset and f

the balance and if I go back to my

codator, it will trigger the event based

on the event model we have initialized

and it's going to fetch out the balance

of that particular wallet. So this is

the wallet number one and it's got the

details and that's what we have. So it's

a very powerful project which help you

to understand that how core blockchain

exactly work how you can build your own

blockchain customize it based on your

requirement and you can simply launch

and user will start using your own

native blockchain. So this one is a

really powerful project. I hope you have

understood that what are the feature and

functionality we have included and how

every single thing will come together.

You can see all the logs all the

transaction model we are getting right

up here. It's a really powerful project

which you can include in your portfolio

to understand that how exactly

blockchain work if you want to develop

your own blockchain. What are the things

are required? What are the technology?

What are the understanding you have to

know? What are the tools you have to

understand to build your own custom

private blockchain? Because right now

you will find that this one is going to

be a very hot topic. A lot of company, a

lot of sectors going to launch their own

private blockchain for their data

structure. You will see this in the

financial model. You will see this in

the health management. You will see in

the supply chain management there you

will find these projects going to take

where you will have your own private

blockchain which deal with your own

supply chain management. So I hope you

have understood all the feature and

functionality we have included in this

particular dab. So now let me provide

you all the asset which you need to

develop this application including the

finance source code so you can faster

your development. So to get that you can

come back to the blockchain coder. I

will also provide you the link in the

description. So you can click there and

you can come back to the blockchain

coder. Here you will find all the

project we have developed. So we have

more than 120 project. So make sure to

go through each one of the projects. So

make sure to log in and once you will

log in you will have all of this option.

You can click on this click on this

source code and you will come back here

and you will find all the project we

have developed. So I would highly

encourage you to go through each one of

this project and build at least five of

them. So when you will develop five

project you will have the understanding

that how blockchain exactly work. So

click on this click on this recent

project and this is the one you have.

Click on this and you will come back

here. Click on this starter file and it

will take you to GitHub and here you

will find all the assets which is

required for you to develop this

particular project. So you can see we

have the UI, we have the blockchain

front end, the explorer, we have the

private blockchain, we have the readmi

file and there you will find all the

important details is already given. So I

would highly encourage you to simply

clone this particular repository. So

when the final project will come, we can

start working straight away and building

this one. Now let me provide you the

final source code and tell you how you

can do the setup once you will get the

final source code. To get that you can

come back to the blockchain coder and

when you will take the final code you

will give your valuable contribution to

my team to bring more tutorial like

this. Once you will download the final

source code you will get the zip file.

Make sure to extract the zip file and

you will get this folder in which you

will have the complete source code of

the entire private blockchain. So we

have the private blockchain. This is the

block explorer we have and this is the

readme file and this is the folder you

have to open in your VS code. So make

sure to install a zip extractor then you

can able to extract this particular

folder. Now I'll open this folder in my

VS code. So I'll click here. I'll go

back to open. Go back to my desktop and

click on this folder we have extracted

and click on open. Now let me give you a

complete walkthrough of the entire

architecture because this one is very

important for you to understand that

what logic we have implemented and how

we have built our entire back end and

how we can initialize each one of the

project. So once you will open the

project in your VS code you will find

the blockchain front end which is the

explorer where we have connected with

our private blockchain to see all the

transaction and here we have our private

blockchain in which you will find all

the code for our private blockchain and

here we have the readme file in which

you will find all the important details

which you can simply go through that and

try to understand. So now let me take

you to the first thing which is our

front end. You will find the very first

folder we have is the app in which we

have the global setup like the CSS

layout and the pages. You don't need to

make any changes and you can see all

these red lines. I have a different

configuration in my pier. That's why I'm

getting it's not an error. So just keep

it as it is. You don't need to make any

changes at this moment. Just test the

way I'm doing it. After that do all the

experiment from your end. But first test

as it is. Close this one. The next one

we have is the component in which you

will find all the component we have

developed for our block explorer. That's

all you will find. Just keep it as it

is. Close this one. The next one we have

is the library in which you will find

the API endpoint because we have

connected our blockchain with the API to

fetch the data and display and perform

all the transaction. So just keep it as

it is. Close this one. We have our

environment variable where we have keep

our API endpoint and we have the islain

get ignore and this is the architecture

which I have given. So you can simply go

through that to understand that what

architecture we have implemented on the

front end side to understand the entire

project explorer. Got it. We have the

next config file. Just keep it as it is.

We have the packages and file. And this

one is very important. No matter when

you are developing this project after 5

years, 10 years, as long as you follow

this particular video and use the exact

version, every single thing would be

working absolutely fine. So just keep it

as it is. Don't need to make any

changes. Close this one. Come back to

the post CSS. We are using Telvin CSS

for the styling and that's the

configuration we have done. Come back to

the Telvin config file. This is the

entire code for our Telvin configuration

like the gradient color, the animation.

That's all we have. And we have the TX

configuration. Just keep it as it is.

This will happen. This handles our

Webpack model. So just keep it as it is.

So that's the complete code we have in

our block explorer which is a blockchain

front end. Don't need to make any

changes. Just test as it is. Close this

one. The next one we have is the private

blockchain and here we have the core

functionality of our private blockchain

where we are performing the

cryptocurrency event model transaction

wallet handling that's all we have here

so don't need to make any changes just

test the way I'm doing it after that

make all the experiment so inside this

private blockchain folder you will have

this particular folder called src and

this is the architecture we have

designed for this particular project so

we have tried to break down the entire

blockchain feature into a microats So

one particular feature will deal with

one particular transaction model. So if

you open this blockchain there we have

this four model blockchain contract

manager and transaction. This all work

as a micros to deal with particular

model. So just keep it as it is. Don't

need to make any changes. Close this

one. Come back here. Come back to the

network. And here we have built this two

different model. one for our API server

means the explorer can interact and call

all the blockchain functionality to get

the data and here we have this P2P

server which allow us to integrate with

the web3 wallet to perform the

transaction and execute the blockchain

model so that's all we have here close

this one close this one come back to the

RPC and this RPC server will allow us to

communicate with the contract so we can

able to perform the transaction and have

all the data so just keep it as it is

don't make any changes close this one

come back to the wallet and here we have

the wallet integration model. We have

included the event model which you can

easily able to customize and add more

feature on top of it. So we it's deal

with the wallet integration to perform

the transaction in the crypto wallet

including in the explore model. Close

this one and here we have the main file

which allow us to start our entire

private blockchain. So just keep it as

it is. Don't need to make any changes.

Just go through the code try to

understand. we have follow a very simple

architecture but this is what you will

find in the actual industry which deal

with the private blockchain let's close

this one and that's what we have in the

src folder so close this one now come

back to the environment variable and

here you will find that I have already

given all of this details so just keep

it as it is don't need to make any

changes first try to understand and test

after that do all the experiment so we

have the server port for the back end

for the RPC endpoint and here I have

initialized the auto mine to false so

when we'll start the blockchain it will

be auto automatically. So just keep it

as it is. Here we have the endpoint for

the websocket and the local host. Keep

it as it is. And this is the network

configuration which you have to add in

your metam mask to connect with our

private blockchain. So this is the chain

ID. This is the name. This is the symbol

and this is the RPC URL. You will find

the difficulty level we are following to

two. And we are providing 100 as a

mining reward. And this is the command

which I have given. So if you face any

error related to server running already,

you can simply execute the command in

your terminal and it's going to stop all

the server. So just keep it as it is.

Close this one. This is the get ignore.

Just keep it as it is. Don't make any

changes. And the next one we have is

this Genesis account. So I have already

given you this accounts which I have

generated and you can simply import the

same account which I have in my wallet.

But you can also delete this one. And if

you delete this one, so our system will

look for this particular file. If it's

not there, it's going to recreate this

particular file, a new account for you.

And each account will have 10,000

PB PCB token.

So this is what I have. So I would

suggest you to simply delete this one.

It will be generated automatically. So

you can import this account into your

metam mask. Now come back JSON file and

these packages are the most stable

version. So no matter when you are

developing it will work absolutely fine.

So first as it is after that do all the

experiment. So close this one and we

have the rhymi file which you have

already explored. So I hope you have

understood the complete architecture of

this particular project that how we are

executing our back end and what we have

in our front end explorer. Now let's try

to do the installation of each one of

these project and let's try to execute

that. So first what I will do I'll going

to drag it here and I'm going to open up

my terminal. Right now you can see I'm

on the main directory blockchain. So

first I have to go back to in this

particular directory then I have to go

back to in this particular directory. So

I'm going to explit my terminal. I'm in

the main directory. So first I'll type

cd

private

chain because I have to get into this

particular directory. Hit enter and I'm

in this particular directory private

blockchain. Now I have to do the

installation of the packages. So simply

type npm I hit enter and it will start

the installation of the package. So just

wait, don't interrupt. Give some time.

The installation will take a little bit

time depending on your internet speed

and your system configuration and how

fast your system is. So don't interrupt

just wait and let it be let the

installation get complete. By the time

it's installing I can come back this

side and I'm going to get into this

particular directory blockchain front

end. So I'll type cd. I'll say

blockchain

chain

front end. Hit enter. Now I'm in this

particular directory. You can see we are

done with the installation and we have

zero vulnerability. You are getting this

particular warning depreciated

depreciated signity ignore that we are

following the stable model. So no matter

when you are developing this project it

will work absolutely fine. So we're done

with the installation. I'll simply

select here and I'm going to clear my

terminal. So we're done with

installation and we got our node module.

Now we have to do the installation in

our front end as well. I'll simply type

npm I hit enter and it's going to start

and it will start the installation of

the packages. So just wait soon the

installation will complete and we'll

start testing our application. So right

now it's installing. What I can do I can

come back here in the private blockchain

and I can see I got the node modules and

this one is also got installed. Simply

ignore all of this warning. Clear up

your terminal. Now we are ready to start

our private blockchain. So first you

have to start your private blockchain.

So I'll simply come back here and type

npm

start and hit enter. And this will start

our private blockchain. you will find

that it will automatically create our

genesis account. So it will create these

five account and you can simply import

these private key in your metamas and

you can able to perform the transaction

and each one of these wallet will have

10,000 PBC token. You can see it started

successfully. Let me drag it here and

let me give you a quick overview.

Bring it up here. You can see this is

the command we have executed first. What

it does? It will run this particular

script and it will check for this

particular file. So this file was not

there. So it created the brand new five

account for us and it funded 10,000 PBC

token in each one of this account. So we

can able to perform the transaction and

here you will find the details. So you

can simply copy the private key in your

metamas and you can simply add the

wallet. And if you want to do the

network configuration in your metamas,

this is what you have to add. So let's

do that. Here I am. I can come back

here, go back in the Metamas and I'm

going to delete my private blockchain

which I have already added. So make sure

to activate your test account in your

Metamas. So I'll simply click here. I

will select this Sofali. I will select

this Sofali. Now I can click here and I

will delete this one. Delete this. I

deleted that particular private

blockchain. Now I can come back here and

I'm going to delete this account as

well. So let's delete this one because

these are the account which I have

created for my private blockchain. So

let's do that. You can or you can keep

it. There is no problem in that. But let

me do it for fresh. So I'll simply come

back here. Click on this details. Click

on this remove. And there is one more

go. I'll click here details and remove.

And right now you will find these are my

one and two is my real account. Now I'm

ready to add the network first. So make

sure to activate your test network. Then

you will have the option for custom and

there you will find all the network. So

to add the network we have to click on

this add custom network and we have to

add the details. So I can call it

private

chain and we have to add the RPC RPC

URL. So this is the RPC URL and we have

the chain ID 1 2 3 and PBC is the

symbol. Let's come back. Click here.

Click on this add. Paste the URL. Click

on this add URL. Let's add the chain ID

1 2 3 4. And we have the symbol is going

to be PBC.

Okay. Now click on this save and once

you will save you will have the network

available. Now you can click on this

private network and it's added

successfully. Right now I don't have any

fund in my account one or if I go to my

account two it's absolutely zero. So now

what I have to do I have to import the

account which I have created. So I can

simply come back to my terminal and you

will find that here I got this account.

I can also get the same account right

from here. I can get the private key

from here or I can get it from here. So

let's import the very first one. This is

one. Copy this one. And that's what I

can import. Click here. Click on this

add wallet. Import. Paste the private

key. Click on import. And it will be

import the account. If you select, you

will find the token is available. Now I

can able to do all the transaction.

Let's import one more account. I can

come back here. I'll import this. Copy.

Come back to the browser. And I can

import one more account. Let's click on

this add wallet. Click here. Paste the

private key. Import. And here I have

imported one more. I got this 10,000 PBC

currency. Now I can able to do the

transfer very easily. So if I come back

to my terminal, if I show you the

transaction log, the moment I'm changing

the account, it's fetching the balance.

I hope you can see that the moment I'm

changing the account in my Metamas and

calling the private blockchain and it's

fetching the data. So this is what we

have imported the second account and

it's fetch the data that which is the

address and the fund. If I try to

perform the transaction is going to

reflect that all here. So let's try to

perform couple of transaction through

our metam mask. So I'll come back to my

metamas and let's try to transfer the

token to my account number one. So I'll

click here. Go back to account number

one and I want to transfer let's say

444.

Click on this and you can see the

transaction log. That's all we have.

Click on this confirm. Simply ignore

this one because we are not following

the event. Come back here and see the

fund right appear. You can wait or you

can simply go straight away right up

here to the account number one and you

will find the fund will reflect here

soon and we got the fund and you can

also see the transaction log in your

metamas. You can see the transfer we

have done to account number one. You can

see the transaction detail and that's

all is there. In the same way if you

want to perform more transaction you can

do that very easily. Come back here and

if I want to transfer let's say more I

can do that. I can come back to account

number three because I have done the

previous transfer to the account number

four. I got it. If I want to do the

transfer more, I can simply select come

back here. Go back to account number two

and let's try to give this and click on

this continue. Click on this confirm and

the transaction pending. Simply ignore

this one. Come back here and you can see

the fund will go down. It takes a little

bit time because we have auto mining

system as well. Or you can simply come

back here. Go back to account number two

and you will find the fund is going to

reflect here. We're done with that. If

you check your terminal then you will

find the block mining and the

transaction model and the balance

fetching is all working fine. So our

private blockchain is running absolutely

good. We can able to interact and

perform the transaction and we have

connected with our metamas. Now let's

try to start our block explorer. So I'll

simply come back here and this is the

block explorer. I got it. I'm in this

particular directory blockchain front

end. Now we have done the installation

as well. So I'll simply open this one

and we haven't done the installation

yet. Yes, we have done it. Now I have to

start the front end. I'll say npm run

dev. Hit enter and it will start our

front end and you will find the details.

So our on this particular port I'll

simply copy and come back to the

browser. I'm going to simply close this

one. Close this one. Open a new tab and

paste here and hit enter and you will

find that our private block explorer is

running absolutely fine. Simply ignore

this one. It will only display in the

dev environment. The moment I will

reload it will gone. Okay. So it's not

an error. It's just a warning. Right now

you will find that we have performed two

transaction and that's all is there. So

right now we are on the block number

three. If you go back to the block

explorer you will find the transaction

we have done. That's what is reflecting.

If you come back here to the wallet
