The presentation provided an overview of cryptocurrency, including its key features, history from Bitcoin's launch in 2009, and examples like Bitcoin, Ethereum, and Ripple. Cryptocurrency uses cryptography to secure transactions and control the creation of new units in a decentralized, peer-to-peer system without intermediaries. Risks of cryptocurrency include hackers targeting systems and lack of protections if something goes wrong with companies holding cryptocurrencies. The future of cryptocurrency may include more retailers accepting it and reduced volatility increasing its common usage similar to credit cards.

•OVERVIEW

3.  A Crypto Currency is a Digital asset designed to work as a
medium of exchange that uses Cryptography:-
• To secure it’s transactions.
• To control the creation of additional units.
 Crypto Currency is a type of Digital Currency , Alternative
Currency and Virtual Currency.
 Fully Decentralized
 Crypto Currency is produced digitally , stored digitally and
transferred digitally.

4.  Crypto Currency is a digital
money , created from code.
 Free of all government oversight.
The crypto currency economy is
monitored by a peer-to-peer
internet protocol.
 Crypto Currency is an
encrypted string of data or a
hash, encoded to signify one
unit of currency.
 Examples of Crypto currency:-
Bit coin , Ethereum, Ripple , etc.

5.  In 1998, Wei Dai Published a Description
of “B-Money” , an anonymous , distributed
electronic cash system.
 Nick Szabo created “Bit Gold” Like bit-
coin and other crypto currencies .
 The first Crypto currency to capture the
public imagination was Bit-coin , which
was launched in 2009 by an individual or
group known under the pseudonym Satoshi
Nakamoto.
 Since then numerous Crypto currencies
have been created.

10.  Bit coin- launched in 2009
 Litecoin – launched in 2011
 Ethereum (ETH)- launched in 2015
 Dash- launched in 2014

11.  There is no control of anyone over this currency, nobody can
manipulate it, nobody can govern it.
 The first decentralized crypto currency , Bit coin , was created in
2009 by pseudonymous developer Satoshi Nakamoto.
 In April 2011 , Name coin the first altcoin , was created to form
a decentralized DNS to make internet censorship more difficult.
 In October 2011 , Litecoin was released and became the first
successful crypto currency to use scrypt as its hash function.
 Ripple coin,(2011),was built on the same protocol as Bitcoin but
services as a payment system- PayPal that supports any fiat
currency , crypto currency , commodity.

12.  Block chain
 Time stamping
 Mining
 Wallets
4/1/2018 12

13.  A Block chain is a continuously growing list of records,
called Blocks, which are linked and secured
using cryptography.
 Provides validity of crypto currency.
 Each block typically contains a hash pointer as a link to
a previous block, a timestamp and transaction data.
 By design, Block chains are inherently resistant to
modification of the data.
 Highly secure and fault tolerance.
4/1/2018 13

14.  It works like a ledger and is
shared by everyone.
 All Bit coin transactions ,without
exception ,are recorded here.
 Once it is recorded , it cannot be
reversed (to prevent the double-
spending problem).
 Everyone will have the same
Block chain and therefore the
access to the recorded history
transactions is easy

1. A wants to send
money to B.
2. The transactions is
represented online
as a ‘block’.
3. The block is broadcast to
Every party in the networks
4. Those in the network
approve the
transaction is valid
5.The block then can be added
To the chain which provides
An indelible and transparent
Record of transactions.
6. The money moves
from A to B.

16.  Crypto currencies uses various time stamping schemes to avoid
the need for a trusted third party to timestamp transactions
added to the block chain ledger.
 Proof-of-work schemes :- The first time stamping scheme
invented was the proof-of-work scheme. SHA-256 and scrypt
are Proof-of-work algorithm.
 Proof-of-stake and combined schemes :- Some crypto
currencies use a combined proof-of-work/proof-of-stake
scheme. The proof-of-stake is a method of securing a crypto
currency network and achieving distributed consensus through
requesting users to show ownership of a certain amount of
currency. It is different from proof-of-work systems that run
difficult hashing algorithms to validate electronic transactions.

17.  Mining is the process by which a
computer solves a complex math problem
in the hopes of uncovering a new crypto
coin.
 Crypto Currency algorithms are used to
mine coins .There are two different
algorithms that are used for almost all the
coins that is in existence today , which is
the SHA-256 and Scrypt algorithms .
 Anyone can mine with their computer’s
processor, more advanced graphics cards
(GPUs or ‘gaming cards’),and specialized
hardware(ASIC systems).
4/1/2018 17

18.  Crypto Currency obtained from mining or purchased can
be stored in an “e-wallet” in one of two ways:
1. Locally on your computer
2. Online
 E-wallets use private and public keys (cryptography) to
secure and transfer your coins.
 Crypto Currency are traded by sending from your wallet
to the “address” of the recipient’s wallet .Or by
scanning a QR code that corresponds to the recipient’s
wallet.

19.  Bit coin is a crypto currency and worldwide payment system.
 It is the first decentralized digital currency.
 Peer-to-Peer technology and no central authority or banks or
intermediately.
 Open-Source , design is public , nobody owns controls of Bit coin.
 21 million Bit coins are issued .
 Each unit of Bit coin is called Satoshi.
 The value of Bit coin is determined by the “Laws of supply and
Demand”.

Protocol: sending BTC
1. Craft a transaction.
2. Give it to your Computer.
Protocol :participating
On valid transactions:
1. Update ledger.
2. Pass the transaction

21.  Bit coin makes heavy use of
the cryptographic hash
function SHA256, which
stands for secure hash
algorithm 256-bit.
 The SHA algorithms were
originally developed by the
NSA.
4/1/2018 21

22.  Yes , depending on what you are doing with it.
 The RBI says that it has not given license/authorization to any
entity/company to operate such schemes with bit coin or any Crypto
Currencies.
 On 13th August , 2017 Nepal declared BTC as illegal.
 China prohibited financial institutions from handling Crypto Currencies.
 Bangladesh Outlawed Bit coin.

24.  Find a good Bit coin wallet.
 Choose the right Bit coin trader.
 Select your payment method.
 Buy some Bit coin and store
them in your wallet.
 Get ready to use it.
4/1/2018 24

25.  More than 40 years of data retention.
 Compatible with many supporting hardware.
 No separate card reader is required is required to access
our card.
 Reusability of our card is unlimited.
 External complexities are less.
4/1/2018 25

26.  www.btc-e.com and bitstamp.com
 You can send the currency from
your wallet to the exchange
,convert it to whatever currency
you desire (USD , Euro , or
Ruble).
 You can send it to your bank
account through a wire transfer.

Crypto Currency market capitalizations as of 27 January 2018, in billions of US
dollars.

28.  Hackers. Crypto currencies are targets for
highly sophisticated hackers ,who have
been able to breach advanced security
systems.
 Fewer protections. If you trust someone
else to hold your crypto currencies and
something goes wrong , that company
may not offer you the kind of help you
expect from a bank or debit card provider.
 Cost. Crypto currencies can cost
consumers much more to use than credit
cards or even regular cash, often due to
price volatility.
4/1/2018 28

29.  More retailers will begin to
accept BTC.
 Used in international trading to
avoid currency exchanges.
 Become as common as credit
cards.
 Less volatility in hard currency
value.
 Reduces the limitations of crypto
currency presently face.

30.  Recently a digital
currency has been
announced by the
name ‘laxmicoin’.
4/1/2018 30
Indian Telecomm
company Reliance JIO
will be launching new
crypto currency very
soon.

31.  Crypto Currency is an impressive technical
achievement, but it remains a monetary experiment.
 Even if Crypto Currencies survive , they may not fully
displace flat currencies.
 As I have tried to show in this presentation , they
provide an interesting new perspective from which to
view economic questions surrounding currency
governance , the characteristics of money , the political
economy of financial intermediaries , and the nature of
currency competition.
