2. WHAT IS BITCOIN?
 A peer-to-peer internet currency that
allows decentralized transfers of value
between individuals and businesses.

3. BITCOIN THE PROTOCOL
 A distributed network that maintains a
ledger of balances of bitcoin-the-
token.
 Otherwise known as the Block Chain.

4. HISTORY OF BIT COIN
 In 1983, American cryptographer David Chaum
conceived of a type of cryptographic electronic
money called ecash.
 Later, in 1995, he implemented it through
Digicash an early form of cryptographic electronic
payments.
 In January 2009, Bitcoin was created by
pseudonymous developer Satoshi Nakamoto.

5. UNITS AND DIVISIBILITY
 The unit of account of the bitcoin system
is the bitcoin.
 Currency codes for representing bitcoin
are BTC and XBT.
 Its Unicode character is ₿.

6. BLOCKCHAIN
 A publicly accessible Ledger
 Ordered chronologically in blocks
 Unchangeable
 Verified by a decentralized network of
miners

7.  The bitcoin blockchain is a public ledger
that records bitcoin transactions.
 It is implemented as a chain of blocks,
each block containing a cryptographic
hash of the previous block up to the
genesis block in the chain.

8. WHAT IS BLOCK CHIN?
 A blockchain is a type of distributed ledger
technology (DLT) that consists of growing list of
records, called blocks, that are securely linked
together using cryptography.
 Each block contains a cryptographic hash of the
previous block, a timestamp, and transaction
data.

9. DATA STRUCTURE OF BLOCKS IN THE LEDGER

10. OWNERSHIP
 Users create accounts called wallets.
 Wallets are secured using passwords and
contain the private keys used for
transferring bitcoins.

11. BITCOIN TRANSACTION VISUAL

12. MINING BITCOINS
 Miners solve complicated algorithms to
find a solution called a hash.
 Finding a hash creates a block that is used
to process transactions.
 Each new block is added to the block
chain.

13. WALLETS
 A wallet stores the information necessary
to transact bitcoins.
 While wallets are often described as a
place to hold or store bitcoins, due to the
nature of the system, bitcoins are
inseparable from the blockchain
transaction ledger.

14. E-WALLETS

15. COLD STORAGE
 Wallet software is targeted by hackers
because of the lucrative potential for
stealing bitcoins.
 A technique called "cold storage" keeps
private keys out of reach of hackers.
 This is accomplished by keeping private
keys offline at all times.
