1. CRYPTOCURRENCY
Bitcoin,Ether & Beyond.

2. What is a cryptocurrency?
If you take away all the noise around cryptocurrencies and reduce it to a simple definition, you find it to be just limited entries in a database no one can change without fulfilling specific conditions.
Bitcoin & Ether

3. Three Axis of Cryptocurrency
TECHNOLOGICAL AXIS
PHILOSOPHICAL AXIS
FINANCIAL AXIS

4. The Technology
The technology of the cryptocurrency means the underline principle through which the transactions take place.
Blockchain is the backbone of Bitcoin
Ethereum is the backbone of Ether

5. The Blockchain
Blockchain is the decentralized technology that enables transfer of bitcoin from one individual to another
Bitcoin =! Blockchain
Blockchain solves the conventional problem of Money Transfer

6. Conventional Way of Transferring Money
THIRD TRUSTED PARTY $5
$4.9 B

7. How blockchain is better than conventional way
Blockchain removes the 3rd party
Blockchain removes the fee of transfer
Blockchain does it way quicker

8. Distributed Open Ledger in Blockchain

9. Distributed Open Ledger in Blockchain$5
A = $10 A B
A->B = $5
A->B = $5
A = $10
A = $10 D C
A->B = $5
A->B = $5

10. Distributed Open Ledger in Blockchain$5
A = $10 A B
A->B = $5
A->B = $5
$15
A = $10
A = $10 D C
A->B = $5
A->B = $5

11. Miners in Bitcoin Miners are special nodes in the blockchain
They Compete against each other to
Validate
Find the key to complete the transactions
Miners get financially rewarded

12. One way encryption
One way hash encryption is used in cryptocurrency (SHA -256)
0110…01 => e131nd21
A fixed size output is produced
Even one bit change would lead to entirely different output

13. Merle Tree A
Key B
Key C D E

14. Blockchain is a huge Mertle Tree

15. Ethereum Blockchain
Ethereum uses turing complete(Solidity) as a programming language
Smart Contracts
Transactions in Etherum can be programmed
Solidity has loops
Ethereum has fees for each operation solving the spam problem
Ethereum is a platform for decentralized application
Microsoft is investing heavily in Ethereum

16. Ethereum vs Ethereum Classic
The battle of the both is a philosophical battle
The DAO aka the Decentralized Autonomous Organization was a complex smart contract which was going to revolutionize Ethereum forever.
The way it worked was pretty straightforward. If you wanted to have any say in the direction  that would get funded, then you would have to buy “DAO Tokens” for a certain amount of Ether.
A group of hackers found a loophole and took out 50 million dollars worth of ether

17. Rate of Bitcoin 167107.64 Indian Rupee
This rate was ruppes in my last presentation

18. Rate of ETH
₹17,471
On 21st June the price of Ether dropped to 10 cents
Stop losses were executed
Ether doesn’t have circuit breaker
