BLOCKCHAIN BASICS
(WHAT IS BLOCKCHAIN?)

What is Blockchain?
Blockchain is a type of database
It differs from a typical database - stores information
Blockchains store data in blocks that are then chained together
Different information can be stored on a blockchain - most
common as a ledger for transactions

Decentralized - so that no
single person or group has
control—rather, all users
collectively retain control.
Decentralized – immutable
(data entered is irreversible)
What is Blockchain?

How Blockchain Works?
Nodes receive a
reward for the proof
of work
Nodes validate the
transaction
A block that represents
the transaction is
created
The block is sent to every node
in the network.
(A node is a computer connected to
other computers which follows rules and
shares information)
A transaction is
requested
The block is added to
the existing
blockchain
The transaction is
completed

Hashing Function
A hash function is a mathematical function that converts a
numerical input value into another compressed numerical value.
The input to the hash function is of arbitrary length but output is
always of fixed length.
Values returned by a hash function are called message digest or
simply hash values.

P2P Distribution Ledger
Participants in the network govern and agree by consensus on
the updates to the records in the ledger
A peer-to-peer (P2P) service is a decentralized platform
Two individuals interact directly with each other, without intermediation by a third party
The buyer and the seller transact directly with each other via the P2P service.
A distributed ledger is a type of database that is shared, replicated, and synchronized
among the members of a decentralized network

A blockchain validator is someone who is responsible for verifying transactions on a blockchain.
Once transactions are verified, they are added to the distributed ledger.
Verifying that transactions are legal (not malicious, double spends etc)
Mining is A peer-to-peer computer process
Blockchain mining is used to secure and verify bitcoin transactions
VALIDATION & MINING

CONSENSUS
Two or more parties agree on the correct state of data on the system and synchronize the data
on the blockchain.
Means each copy of the shared ledger will have the exact same data.
Consensus protocol makes sure that every new block that is added to the Blockchain is the one
and only version of the truth that is agreed upon by all the nodes in the Blockchain
Without consensus, deals and transactions fall apart and are not saved to the blockchain
because they are never agreed upon.
Layman’s term - consensus serves to help two or more parties that don’t trust each other to
trust each other.

There are different
consensus
algorithms. Examples
of enterprise
blockchain consensus
algorithms include:
Proof of Work (aka
mining) which
requires network
users to resolve a
complex
mathematical puzzle
with the goal to
validate a
transaction and
create a new block
Proof of Stake (PoS)
which selects the
creator of the next
block based on
several stake related
factors such wealth
and age
Proof of Elapsed Time which is a hybrid
of a random lottery and first-come-first-
serve basis
Proof of Authority which requires
sign-off by a majority of designated
nodes for a block to be created
CONSENSUS

Proof of Work & Proof of Stack
Proof of Work requires ALL of its miners to attempt
to solve a complex sum, with the winner determined
by the person who has the most powerful/quantity
of hardware devices.
Proof of Stake model randomly chooses the
winner based on the amount they have staked.

Data on a public blockchain are secure as it is not possible to modify or alter data once they have
been validated on the blockchain
A public blockchain is decentralized and does not have a single entity which controls the network
Anyone can join the network and read, write, or participate within the blockchain
A public blockchain is permissionless
Public Blockchains
Bitcoin and Ethereum are well-known examples of a public blockchain.

Private Blockchains
In a private blockchain, only the entities participating in a transaction will have knowledge about it,
whereas the others will not be able to access it
There are one or more entities which control the network and this leads to reliance on third-parties
to transact
Private blockchains work based on access controls which restrict the people who can participate in
the network
A private blockchain is a permissioned blockchain
Hyperledger Fabric of Linux Foundation is a perfect example of a private blockchain.

SMART CONTRACT
Contracts, whether they are leases, mortgages,
loans, or for services, have been around a long
time
But when something goes wrong and one party
fails to perform their part of the contract, what
happens?
Then you have to go back and forth with them
until they come around. And if they don’t?
Then you have to call an attorney or a mediator to
help persuade them
At that point, you are looking at spending hours
and thousands of dollars to get the other party to
simply execute their half of the contract

SMART CONTRACT
Smart contracts are kept on the blockchain and
are executed automatically when a transaction is
processed.
Because data on the blockchain is immutable –
cannot be changed or manipulated by anyone

SMART CONTRACT
For example, if you are a landlord your tenants
have leases
The smart contract contains
key data of both parties
such as the name, contact
information, bank account
details as well as
information about the lease
itself including lease amount
and payment date
When a smart contract
self-executes on the pre-
defined lease payment
date, it automatically
withdraws funds from the
tenant’s bank account
and deposits the funds
into your account
This saves you the monthly
rental statements in advance,
of reminding the tenant to
pay, and from hounding the
tenant once the late date has
passed, never mind eviction
notices, court dates, and
attorney’s fees.

WHAT IS CRYPTOCURRENCY?
Cryptocurrency is decentralized digital money
or virtual currency
Based on blockchain technology and secured
by cryptography which makes it nearly
impossible to counterfeit or double-spend
Example of Cryptocurrency….
5,392 cryptocurrencies
Total market capitalization of $2.23 Trillion

How safe is Cryptocurrency?
As with buying and trading commodities and
fiat currencies, purchasing a
cryptocurrency—isn't free of risk
Volatile price may make it riskier than stocks
and other types of investments, but that
volatility can potentially make it more
profitable too

You can use crypto to buy regular goods and
services, although many people invest
in cryptocurrencies as they would in other
assets, like stocks or precious metals.
Is Cryptocurrency a good investment?
If you believe in blockchain technology,
cryptocurrency
is a great long-term investment.
Bitcoin is seen as a store of value, and some
people think Bitcoin can replace gold in the
future

Ethereum, the 2nd largest cryptocurrency by
market cap, also has huge growth potential as
a long-term investment
Every cryptocurrency has its own function and
usability
BITCOIN – P2P monetary exchange
ETH – more to smart contract

WHERE TO INVEST?
What crypto will explode in 2020?
With all that in mind, I suggest readers keep a close eye on these seven
(might be) explosive cryptocurrencies in the coming year:
DxChain Token (DX)
Bitcoin (BTC) Zcash (ZEC) Ripple (XEC)
Basic Attention
Token (BAT)
Chainlink (LINK)
Synthetix Network Token (SNX)

Released as open-source software
Bitcoin is a decentralized digital currency
Can buy, sell and exchange directly, without an
intermediary like a bank
Began use in 2009
Unknown person or group of people using the
name Satoshi Nakamoto
“An electronic payment system based on
cryptographic proof instead of trust.”
Bitcoin is a cryptocurrency invented in 2008
WHAT IS BITCOIN (BTC) AND HOW IT WORKS?

WHAT IS BITCOIN (BTC) AND HOW IT WORKS?
Will Bitcoin die?
However, it's possible the bitcoin network
protocol will be changed between now and
then.
Bitcoin is not regulated as it is not considered
to be electronic money according to the law.
Bitcoins are still accepted by small businesses
and merchants
In actuality, the final bitcoin is unlikely to be
mined until around the year 2140.
While it warned the public of risks of bitcoins,
and that they are not legal tender

ETHEREUM (ETH) FUNDAMENTALS
Can buy, sell and exchange directly, without an
intermediary like a bank
Open-source, blockchain-based, decentralized
software platform used for its own
cryptocurrency, ether
Enables SmartContracts and Distributed
Applications (ĐApps) to be built and run without
any downtime,
fraud, control, or interference from a third party
Vitalik Buterin is the founder of ETH
Traded as a digital currency exchange like other
cryptocurrencies
Ethereum is a cryptocurrency invented in 2015

ETHEREUM (ETH) FUNDAMENTALS
Latest long-term forecast,
Ethereum price will hit $5,000 by the end
of 2021 **
$10,000 by the middle of 2023.
$20,000 within the year of 2025
$50,000 in 2032.
What will Ethereum be worth in 2030?
Ethereum enables the deployment of smart
contracts and decentralized applications
1 Ethereum = $2630 (RM10,026)
Ethereum to run applications and even
to monetize work

WALLETS FOR CRYPTOCURRENCY
A cryptocurrency wallet is an app that allows
cryptocurrency users to store and retrieve their
digital assets
Wallets can hold multiple cryptocurrencies.
Direct the sender to a unique cryptographic
address issued by the wallet.

Automatically you will have a wallet when you open a cryptocurrency exchange account (exchange-
hosted wallet)
You do not have control of the private and public keys.
In addition, participating in ICOs require you to have your own private wallets, from which to invest
from.

 The Best Bitcoin Wallets of 2021
 Best for Beginners: Exodus.
 Best For More Advanced Users Interested in
just Bitcoin: Electrum.
 Best for Mobile Users: Mycelium.
 Best Hardware Wallet: Ledger Nano X.
 Best For a Large Number of
Cryptocurrencies: Trezor Model T.

Web Wallets
(Least secure, but usable)
5 Different Types Of Crypto Wallets
Mobile Wallets
(Easy access to
your crypto assets)
Desktop Wallets
(Ease of use, but
not very secure)
Paper Wallets
(Not very relevant
anymore, but good to
know info)
Hardware Wallets
(Recommended crypto wallet
type)

Cold storage (or offline wallets) is one of the safest methods for holding bitcoin, as these wallets are
not accessible via the Internet.
Users can lose bitcoin and other cryptocurrency tokens as a result
of theft, computer failure, loss of access keys, and more.

10 Best bitcoin wallets with low transaction fees
Armory - windows/macOS/linux/raspberry pi.
Myceliumwallet - android/IOS.
Wirex - android/IOS.
Xapo - android/IOS.
Blockchain - windows/macOS/android/IOS.
Bitgo - windows/macOS/android/IOS.
Greenaddress - android/IOS.
Coinbase - windows/macOS/android/IOS.
Currently, the Malaysian Security
Commission has licensed three firms to run
exchange platforms :
Luno Malaysia Sdn Bhd,
Sinegy Technologies (M) Sdn Bhd
Tokenize Technology (M) Sdn Bhd.

WHAT IS ETHEREUM AND DAPP
Decentralized Application (Dapp)
A Dapp has its backend code running on a
decentralized peer-to-peer network.
Isolated, which means they are executed in a
virtual environment known as Ethereum Virtual
Machine.
If the smart contract happens to have a bug, it
won't hamper the normal functioning of the
blockchain network
Dapps have their backend code (smart contracts)
running on a decentralized network and not a
centralized server.

WHAT IS ETHEREUM AND DAPP
Dapp Token (DAPPT) is a cryptocurrency token and
operates on the Ethereum platform.
Unlike a regular web app with built-in ads that are
monitored by the company, a DApp runs on its own.
Using the Ethereum blockchain for data storage and
smart contracts for their app logic.
That means users need to put some money into the
system to keep it going. This money helps support the
nodes that work to validate app transactions.

SETUP ETHEREUM WALLET IN METAMASK
MetaMask is a cryptocurrency wallet but also a
web browser extension (available in Chrome,
Firefox and Brave) used to store, send and
receive
Ethereum and ERC20.
In other words, it allows users to make Ethereum
transactions through regular websites.
MetaMask can be used to store keys for
Ethereum cryptocurrencies only.
It works like a bridge between normal browsers and
the Ethereum blockchain
MetaMask generates passwords and keys on your
device, so only you have access to your accounts and
data

BLOCKCHAIN IMPLEMENTATION STRATEGY
Understand What Blockchain Is
 Understand the blockchain ecosystem
 How to implement the system in your business?
Develop A Business Case
Organisations can use to see if the problem they are trying to address could be
solved by blockchain:
 Do multiple parties share data?
 Do multiple parties update data?
 Is there a requirement for verification?
 Do intermediaries add complexity?
 Are interactions time sensitive?
 Do transactions interact?
If you answer yes to four out of six of these criteria, then it shows blockchain could
be a good idea,”
Choose Your Blockchain Carefully
 Understanding the core benefits
 Don’t fall victim to the hype
 Permissioned network? Decentralised or centralised?
 Different chains perform different functions.”

Build An Ecosystem
 The rules for participation.
 How to ensure that costs and benefits are fairly shared.
 What risks and control framework can be used to address the
shared architecture.
 What governance mechanisms are in place, including continuous
auditing and validation, to ensure that the blockchain functions as
designed.
Design Deliberately
 Blockchain has to be designed carefully, not just to solve the
organizational issues, but to ensure it fits with existing processes.
 Working with not just the tech team but also operations and
management, and pick apart the problems and pain points and
build a solution around that
 Privacy implications, cybersecurity, compliance, and how they
work alongside a blockchain
Navigate Uncertainty
 Blockchain still new, regulations very limited; monitor the changing
regulatory framework
 blockchain differ from country to country
BLOCKCHAIN IMPLEMENTATION STRATEGY

BLOCKCHAIN IMPLEMENTATION ON BIG DATA

Using blockchain adds
another data layer to the Big
Data analytics process
Blockchain-generated Big
Data is secure, as it cannot be
forged due to the network
architecture
Blockchain-based Big Data is
valuable, meaning it is
structured, abundant and
complete, making it a perfect
source for further analysis
Other technologies and
computational/mathematical
techniques that
are used in blockchains
include digital signatures,
distributed (peer-to-peer)
networks, and
encryption/cryptography
methods, among others
linking the records (blocks) of
the ledger

What is the difference between Blockchain and Big Data?
Blockchain ensures data storage and privacy to increase
the data integrity, whereas the big data deals
with data ensuring the data quantity, velocity, and variety to
deliver better predictions.
“Data Science for prediction ; Blockchain for data integrity”
Big data is quantity ; Blockchain is quality
The combination of these technologies is unbeatable.

2017 Survey with 16,000 data professionals
 Biggest challenge of data science - Dirty data (duplicate or incorrect data)
 Blockchain solution gives almost impossible to manipulate the data - (huge amount of computing
power required through decentralized consensus algorithm & cryptography makes data security and
privacy.)
 Cyber attackers – data stored in centralized servers – real threat
 Blockchain focus on validating data - Big data focus on making predictions from large amount of data.
 Blockchain integrates with other advanced solution like cloud solutions, Artificial Intelligence (AI) &
Internet of things (IOT)

ENSURING TRUST (DATA INTEGRITY)
 Last year LENOVO conduct a case study to detect fraudulent documents and forms.
 Blockchain technology used to validate physical documents which encoded with digital signatures.
 Digital signatures processed by computers
 Authenticity of the documents recorded in blockchain.
PREVENTING MALICIOUS ACTIVITIES
 Single person can’t pose a threat to the data network as blockchain uses consensus algorithm to
verify transactions.
 A node (a unit) that works abnormally can easily identified and wipeout from the network.

MAKING PREDICTIONS (PREDICTIVE ANALYSIS)
 Blockchain data same like other data, can be analyzed to predict the outcomes as its behaviors &
trends.
 Furthermore, Blockchain provides structured data from individuals and individual devices.
 Data scientists easily can extract data on a blockchain network as its cloud based service and
connected to several thousand computers. Otherwise collecting data is a tough job.
REAL TIME DATA ANALYSIS
 Blockchain exhibited real time transactions across the borders in financial and payment system.
 In the same manner, some organizations requires real time data analysis which can be done through
blockchain technology.
 Real time data make an organization to act fast on decisions, whether it’s to block a suspicious
transaction or to track abnormal activities.

MANAGE DATA SHARING
 Whatever data gotten from studies, can be stored in blockchain.
 Project teams no need to repeat the same data analysis carried out by other teams or wrongfully
reuse data that already been used.
 Can be monetize their work, probably by trading analysis outcomes stored on a blockchain by an
organization.

Example of Blockchain in Big Data

ACTIVITY
1. Choose an industry to implement the innovation of blockchain technology
3. Identify which blockchain platform to use
2. Develop a business case base on your studies
4. Identify what are the pro and cons by using blockchain technology in that industry
