Proposed Bitcoins to

Development Bitcoin Genesis
Block
Cryptographer David
Chaum first
proposed a
blockchain-like
protocol in his 1982
dissertation
"Computer Systems
Established,
Maintained, and
Trusted by Mutually
Suspicious Groups
Further work on a
cryptographically
secured chain of
blocks was
described in 1991 by
Stuart Haber and W.
Scott Stornetta
The first decentralized
blockchain was
conceptualized by a
person (or group of
people) known
as Satoshi Nakamoto in
2008. Nakamoto
improved the design in
an important way using
a Hashcash-like method
to timestamp blocks
without requiring them
to be signed
On 3 January 2009,
the bitcoin network
was created when
Nakamoto mined the
starting block of the
chain, known as
the genesis block
The first transaction
of this type is
registered
on October 12,
2009 where New
Liberty Standard
buys a total of 5.050
BTC from Sirius for
an amount of $ 5.02
through PayPal.
12. What is
CryptoCurrency ??
If you don’t believe it or
don’t get it, I don’t have
the time to try to
convince you, sorry.
– Satoshi Nakamoto
A cryptocurrency, crypto-currency,
or crypto is a digital currency designed to
work as a medium of exchange through
a computer network that is not reliant on
any central authority, such as
a government or bank, to uphold or
maintain it.
13. Type of CryptoCurrency
A cryptocurrency, broadly
defined, is a form of digital
tokens or “coins” that exist
on a distributed and
decentralized ledger called a
blockchain
Coin
A non-fungible token is a non-
interchangeable unit of data
stored on a blockchain, a form of
digital ledger, that can be sold and
traded. Types of NFT data units
may be associated with digital
files such as photos, videos, and
audio
NFT
A utility token is a crypto token that serves some use
case within a specific ecosystem. These tokens allow
users to perform some action on a certain network. A
utility token is unique to its ecosystem
Utility Tokens

Type of Digital wallet
A digital wallet, also known as e-wallet, is an electronic device, online service, or
software program that allows one party to make electronic transactions with another
party bartering digital currency units for goods and services
16. Cryptocurrency wallet
A cryptocurrency wallet is a
device, physical medium,
program or a service which
stores the public and/or
private keys for
cryptocurrency transactions.
In addition to this basic
function of storing the keys, a
cryptocurrency wallet more
often also offers the
functionality of encrypting
and/or signing information.
17. Hot Wallets
and
Cold Wallets
A hot wallet is connected to the
internet and could be vulnerable to
online attacks — which could lead to
stolen funds — but it's faster and
makes it easier to trade or spend
crypto. A cold wallet is typically not
connected to the internet, so while it
may be more secure, it's less
convenient.
