BLOCKCHAIN

5
Blockchain is a transaction database shared by all nodes participating in a
system. In essence, it is a distributed method of tracking and transferring
assets online without need for a trusted party.
What is Blockchain?

6
Imagine there are a group of
lockers in a public place.
Each locker is:
• Free of charge
• Use of “wallets” to keep
track of all owned lockers
• Money is inaccessible if
key is lost
• Has a window
Blockchain Analogy

7
Presume Alice and Bob get into a contract...
• No banks or third party
involvement
• No processing delays
• No additional fees
• The transaction cannot be
reverted
• Only Alice can take ownership
of transferred amount
• The transaction is transparent

Decentralized Money Analogy

8
• The bitcoin network and blockchain system works very similar to the decentralized money management approach
• The bitcoin network consists of thousands of computers (nodes), each of which maintains its own ledger. These computers communicate
with each other by sending messages over the Internet.
• For example, if A was transferring 10 bitcoins to B, A would click initiate the transaction on the bitcoin wallet, and it would broadcast this
transaction to all other bitcoin users.
The Concept of Blockchain

9
• Anyone can join the bitcoin network by
installing the bitcoin software.
• The software automatically downloads
the global ledger – Blockchain, onto the
computer.
• This distributed ledger allows bitcoin
users to see every transaction that has
ever happened in bitcoin’s history! Users
can even browse through them online on
sites.

How a bitcoin transaction takes place
X holds 1 BTC in virtual
wallet with associated
public and private key
Y sends his bitcoin wallet
address and public key to X
X wants to send BTC to Y
who also has a wallet
X creates transaction
message with Y’s address
and transaction amount
X signs transaction with his
private key and announces
his public key for signature
verification
X broadcasts the
transaction on bitcoin
network for all to see

11
Fully Distributed
System
No centralized authority.
Transparency All transactions are publically recorded and available for scrutiny.
Security The ledger is distributed across thousands of computers, meaning a
practical hack is near-impossible.
Risk No single authority has control, which means if there is a fault, the rest of
the network continues.
Privacy The user, or bitcoin owner, is anonymous and doesn’t need to provide ID
credentials.
Dependency Use of the blockchain eliminates dependency on the base layer service
for functionality.
High Network
Effects
There can be substantial benefits from very large groups of people (or
even everyone) using the same service.

Banking giants around the world like Goldman Sachs, Barclays, UBS and others are embracing
bitcoin and Blockchain technology.
Having recognized the potential and advantages of the lightning-fast, decentralized transaction
verification system as having broad applications for transactions involving everything from stock
trades to money and property transfers, banks have been warming to Blockchain technology,
using it to innovate traditional banking processes.
Banks and Blockchain Technology

16
Blockchain is a really disruptive development, and
banks have a lot of fear concerning this
technology because in the pure theory of
blockchain, a lot of processes within a traditional
bank would be obsolete.
