Cryptocurrency

2. What is Blockchain ?
• “The blockchain is a simple digital platform for recording and verifying
transactions so that other people can’t erase them later and anyone can
see them.”
• No one knows who invented blockchain.
• The idea for it came after 2008 financial crisis from a paper
published online.
• The author, Satoshi Nakamoto, is thought to be using a pseudonym.

3. Key concept
• A type of distributed ledger comprises of unchangeable,
digitally recorded data in packages called blocks.
• These digitally recorded "blocks" of data is stored in a linear
chain.
• Each block in the chain containstransactiondata Is
cryptographicallyhashed.
• The blocks of hashed data draw upon the previous-block in
the chain, This ensures all data in the overall "blockchain"
has not been tampered with and remains unchanged.
• The blockchain represents a "golden record" of transactions,
a complete, historical record that technically cannot be
interfered with or undone.

6. What is bitcoin ?

• BUT did you know that Bitcoin is also a giant computing network?

7. Some General Question related to bitcoin
How do people trust in it ?
What is proof of work ?
What is hashing ?
What is the use of private and public key for a
wallet ?
How bitcoin is mined ?

8. Interesting
facts about
bitcoin
• First official transaction
• Market cap
• In 2010 you could have mined 200 bitcoin in just 1
day by your normal pc 1.2 million
• Returns from $.01 to $6500
• How much easy to setup a account

13. Advantages of Bitcoin
• Freedom in Payment.
• Hackproof
• Anonymous
• Control and Security
• Information is Transparent

14. Disadvantages of Bitcoin
• With the absence of any Government backing, Bitcoin’s value is backed by

the flaws of paper-based transaction recording go away when we put
the data on a blockchain. Fraud prevention, low transaction costs,
efficient and secured land title tracking are some of the key benefits

of votes cast and counting of votes by trusting authority to declare

tracking, and counting votes. Delegating audits to the general public
or a group of people will ensure there is no foul play.

18. IOT
• A number of interesting use cases can be solved when we integrate
IoT devices with blockchain. Using blockchain as a public ledger for a
number of IoT devices,
• Databroker allows monetizing sensor data with the help of
blockchain. Slock.it converts any object into a smart object — you can
rent, sell or share anything. Blockchain-based solutions from filament
enable connected machines and devices to transact and exchange
value against a blockchain, taking enterprise and industrial IoT
connectivity benefits to the next level.

19. Payment Settlement
• Blockchain can be used to build a real-time settlement system for
quick payment processing. Ripple has built one such system. Ripple
connects banks, payment providers and digital asset exchanges via
RippleNet to provide one frictionless experience to send money
