2. Agenda
• What is Fintech ?
• What is a blockchain ?
• Current Infrastructure
• What is Bitcoin ?
• Seriously,Be Careful
• About Ethereum
• Mist Browser
• Building Dapps
• IPFS
• IOTA

3. What is Fintech ?
• Fintech is the short form for
Financial Technology
• The term explores and
empowers the beauty of how
the future of financial banks will
be in the future with technology.

4. What is Blockchain ?
• Blockchain is a shared,
immutable ledger for recording
the history of transactions.
• Blockchain is offered using P2P
communication and
cryptocurrency methodology.

5. Current Infrastructure(General Idea)
Middleware like
RuPay,VISA,MasterCard

6. What is Bitcoin ?
• Bitcoin is the first blockchain.
• Introduced in a white paper by
Satoshi Nakamoto.
• Works on a series of new
concepts that have been
introduced in the whitepaper.

7. Seriously !! Be careful !

8. About Ethereum
• Decentralized platform that runs
smart contracts: applications that run
exactly as programmed without any
possibility of downtime, censorship,
fraud or third party interference.
• Comes along a wallet and mist
browser for secure transactions.

9. How to do It ?
• Installing the ethereum cli
$ sudo apt-get install software-properties-common

10. How to do It ?
• Adding the repository of ethereum
$ sudo add-apt-repository -y ppa:ethereum/ethereum
• Update your system
$ sudo apt-get update

11. How to do It ?
• Adding the repository of ethereum
$ sudo apt-get install ethereum
Try it out using:
$sudo geth console

12. Geth
• Geth is a go based
implementation of a console by
Ethereum
• Geth has been audited for
security and will be the future
basis for the end user-facing
Mist Browser.
• For C++ implementation
checkout eth.

13. Mist Browser
• Tool to browse, test and develop
Dapps.
• Easy to use
• Separate browser for all your
transactions.

14. How to do It ?
• Installing Mist Browser from Downloads page:

15. How to do It ?
• Installing Mist Browser from Downloads page:

16. How to do It ?
Wait for the Download to complete & setup your account to get started

17. Ethereum Wallet
• Simple open source wallet to
maintain your ether currency.
• Easily store currency on your
system.
• You can also use several
different 3rd party companies
for managing the wallet.

18. How to do It ?
• Installing Ethereum wallet from Downloads page:
• Rest setup is similar to mist browser setup and ends us with
formation as a account.

19. Building Dapps
• Decentralized Application (or
'Dapp') is a piece of software
consisting of a user interface (UI)
and a decentralized backend;
typically making use of a
blockchain and smart contracts.
• Can be built using various
frameworkssuch as Truffle.

20. About IPFS
• IPFS is peer-to-peer hypermedia
protocol
• Future replacement for https
certificate methodology.
• Each file and its block is given a
unique fingerprint called
cryptographic hash.
• Uses Git like provisioning.

21. The IPFS Stack
• IPFS is peer-to-peer hypermedia
protocol
• Future replacement for https
certificate methodology.
• Each file and its block is given a
unique fingerprint called
cryptographic hash.
• Uses Git like provisioning.

22. How to do It ?
• Download the tar package available at https://ipfs.io/docs/install/.
• Run the installation script, found in the package
• $ ipfs init
Please Note it Down

23. How to do It ?
• Try showing the output using:
• $ipfs cat ($Hash)

24. IoTA
• Applying IoT(Internet of Things)
on blockchain.
• Aims to provide a distributed
ledger for implementing
transaction through IoT.
• Directed acyclic graph (DAG) as a
distributed ledger which stores
all transaction data of the IOTA
network.

25. Banks using it
• NASDAQ – Linq
• CitiBank – CitiCoin – Internal
Trading System
• US Federal Reserve – IBM
Implementation

26. IBM Blockchain
• The aim of IBM is to have a
blockchain that is reliant on the
exchange of cryptocurrencies
with anonymous users on a
public network (e.g. Bitcoin), a
blockchain for business provides
a permissioned network, with
known identities, without the
need for cryptocurrencies.
• Can be integrated with Bluemix
and Watson.

27. Hyperledger Project
• Open source collaborativeeffort
created to advance cross-
industry blockchain
technologies.
• Fabric is way to easily connect
different nodes,blocks and
identities in a secured manner
so that transactions can happen
in a secure manner.

29. Banks Embracing Blockchain & Clouds
