3. INTRODUCTI
ON
Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no
central authority or banks; there are no physical Bitcoin, only balances associated with public and privet key.
The first Bitcoin specification and proof of concept was published in 2009 by Satoshi Nakamoto.

4. HOW DOES BITCOIN WORKS
From a user perspective, Bitcoin is nothing
more than a mobile app or computer program
that provides a personal Bitcoin wallet and
enables a user to send and receive bitcoins.
Behind the scenes, the Bitcoin network is
sharing a massive public ledger called the
"block chain".
This ledger contains every transaction ever
processed which enables a user's computer
to verify the validity of each transaction

5. TRANSFERS
PEOPLE CAN SEND BITCOINS TO EACH OTHER USING MOBILE APPS OR THEIR COMPUTERS. IT’S SIMILAR TO SENDING
CASH DIGITALLY.BITCOIN TRANSACTIONS ARE SENT FROM AND TO ELECTRONIC BITCOIN WALLETS, AND ARE DIGITALLY
SIGNED FOR SECURITY. EVERYONE ON THE NETWORK KNOWS ABOUT A TRANSACTION, AND THE HISTORY OF A
TRANSACTION CAN BE TRACED BACK TO THE POINT WHERE THE BITCOINS WERE PRODUCED.

6. MINING
Bitcoin mining is the process by which transactions are verified and added to
the public ledger, known as the block chain, and also the means through
which new bitcoin are released. Anyone with access to the internet and
suitable hardware can participate in mining. The mining process involves
compiling recent transactions into blocks and trying to solve a
computationally difficult puzzle. The participant who first solves the puzzle
gets to place the next block on the block chain and claim the rewards. The
rewards, which incentivize mining, are both the transaction fees associated
with the transactions compiled in the block as well as newly released bitcoin.

7. OWNING
BITCOINS
Bitcoins are stored in a “digital wallet,” which exists either in the cloud or on a user’s
computer.
The wallet is a kind of virtual bank account that allows users to send or receive
bitcoins, pay for goods or save their money.
Unlike bank accounts, bitcoin wallets are not insured by the FEDERAL DEPOSIT
INSURANCE CORPORATION.

8. WHO CONTROLS THE BITCOIN
NETWORK?
Nobody owns the bitcoin network much like no one
owns the technology behind email or the internet.
Bitcoin transactions are verified by bitcoin miners
which has an entire industry and bitcoin cloud
mining options. While developers are improving the
software they cannot
Force a change in the bitcoin protocol because all users
Are free to choose what software and version they use.

9. FUTURE OF BITCOIN
So what’s next for bitcoin? As outlined previously, it has
many advantages and for this reason it will remain
relevant as a currency.
This is centralized system in bitcoin that’s why this is
more secure and can’t hack able. It is quickest way to
transfer money one country to another country with in
very short time(10 min).
Is bitcoin simply a 21st century version of gold, only
without the storage issues? Or is it just a short-lived
popular fad that may soon evolve into something quite
different? Only time will tell. The only certainty is that
its price will remain very volatile in the future.
