Agenda

Issues with Online Transactions today…
Power is centralized
Incentive is largely lopsided
Security is still a big issue
Privacy is largely non-existent
IP rights are ambiguous
Inclusion is absent
Integrity is an add on

5
Over years, people have been trying to solve this
problem
The Quest for crypto currency and distributed decentralized design methods continue with
projects in the areas of altcoins (namecoin, litecoin, etc), distributed ledgers (ethereum,
factom, hyperledger etc), meta-networks ( e.g. counterparty), currency platforms (Ripple,
cirlce etc.), micro channel platforms (Lightening network etc.) and many more...

Bitcoin Overview
Bitcoin or bitcoin ? --- both valid, but not the same Bitcoin is an overloaded word
• Protocol – specifying how to construct and parse the blockchain, how transactions should be assembled, what is a valid
transaction …
• Network – Peer-Peer network to which nodes connect and exchange messages containing new blocks and transactions
• Currency – unit of the native currency of the Bitcoin network. Each bitcoin is divisible to 100,000,000 pieces called satoshis
• Open Source Project – The original open source Bitcoin core ( written in C++)

8
What is a Blockchain ?
Blockchain is the technology that enables the existence of cryptocurrency
(among other things)
Bitcoin is the name of the best-known cryptocurrency, the one for which
blockchain technology was invented.
A cryptocurrency is a medium of exchange, such as the US dollar, but is
digital and uses encryption techniques to control the creation of monetary
units and to verify the transfer of funds.

11
Why is the idea of blockchain provocative ?
“BlockChain, as a
framework for Value
Transfer disintermediates
the intermediaries”
In other words, you don’t need an
intermediary to do a(ny) transaction

13
How BlockChain designs out the issues we faced
Power is de-centralized
Incentive is largely lopsided reputation
based
Security is still a big issue PKI based
Privacy is largely non-existent decided by
user
IP rights are ambiguous made clearer
Inclusion is absent made possible by lower
transaction costs
Integrity is an add-on intrinsic

14
Smart Contract
• Smart Contracts is defined as a piece code, able to self-verify their own conditions
using data & self-execute by releasing payment, while remaining tamper resistant.
• Smart contracts aim to provide security superior to traditional contract law and to
reduce other transaction costs associated with contracting.
• Smart contracts are not automatically legal contracts.
Characteristics
• Turning legal obligations into automated processes
• Guaranteeing a greater degree of security
• Decreasing reliance on trust
• Lowering transaction costs
• Self-verifying
• Self-executing
• Tamper resistant

15
Types of Block Chain
• Public blockchains are open-source and everyone can be part of them. Anyone in the world can
explore the blockchain, send transactions or contracts, consult them and participate in the
consensus process – the process for determining what blocks get added to the chain and what the
current state is.
• Examples: Bitcoin, Ethereum
Public blockchains
• Consensus process is controlled by a pre-selected set of nodes; for example, one might imagine a
consortium of 15 financial institutions, each of which operates a node and of which 10 must sign
every block in order for the block to be valid. The right to read the blockchain may be public, or
restricted to the participants.
• Example: R3
Consortium blockchains
• Write permissions are kept centralized to one organization. Read permissions may be public or
restricted to an arbitrary extent. Likely applications include database management, auditing, and
more that are internal to a single company, and so public readability may not be necessary in
many cases at all, though in other cases public auditability is desired.
• Examples: Eris Industries, Multichain
Private blockchains

Agenda

17
Global Financial Industry and its shortcomings
It is built on decades old technology
It is at odds with Rapidly Advancing Technology
It is exclusive, leaving billions of people with no access to basic financial tools
It is centralized, exposing itself to data breaches, other attacks, or outright failure
It is monopolistic, reinforcing the status quo and stifling innovation

18
Reasons why Blockchain Technology will disrupt
Blockchain enables Two parties who neither know each other or trust each
other to transact and do business
Attestation
On the blockchain, the network both clears and settles peer-to-peer value
transfers, and does it so continually so that the ledger is always up to date
Cost
A bitcoin network in contrast takes an average of ten minutes to clear and
settle all transactions conducted during that period
Speed
The Blockchain Technology mitigates several forms of financial riskRisk
The Blockchain Technology was designed to move bitcoins, and not other
financial assets. The technology is OpenSource and evolves due to
experimentation
Value
Innovation

Why are we Talking about Blockchain ?
"If, so many incredibly smart people are working on this and
investing their time and energy, let alone the money that is
flowing into it, 'it's not something that we can all ignore.
However, the community of innovators need to understand
the complexity behind payments"
Ebru Pakcan, Head-Global Payments, citi
“The emerging Technology is fascinating and ING is not in
wait and watch mode but we are in see and do mode”
Mark Buitenhek
Global Head of Payments and Cash Management (PCM)
for ING
" I believe - and this is my personal view - that blockchain
technology will not only change the way we do payments but
it will change the whole trading and settlement topic....When
somebody with a strong brand and security level establishes
it as a reliable service, then the whole industry will follow.
That is my personal prediction."
Oliver Bussman, CIO UBS
“As we build more and more complex infrastructure the
whole maintenance and [impact for] changing regulations is
becoming extremely difficult for most of the banks. What is
being demonstrated here is the quite eye opening and
definitely something to look out for."
Gautam Jain, MD & Global Head-Client Access
• The Bank of England recognized the technology as 'significant innovation' that could have "far-reaching implications".
• New York State has released Bitcoin World's first license - BitLicense!
• Financial Conduct Authority (UK) is investigating ways in which the blockchain can be used in the formal financial
services industry

Conclusions of the WEF Report
The World Economic Forum's analysis has yielded six key findings
DLT has great potential to drive simplicity and efficiency though the establishment of
new financial services infrastructure and processes1
DLT is not a panacea; instead it should be viewed as one of the many technologies
that will form the foundation of next generation financial services infrastructure2
Applications of DLT will differ by use case, each leveraging the technology in different
ways for a diverse range of benefits3
Digitial Identity is a critical enabler to broaden applications to new verticals: Digital Fiat
(legal tender), along with other emerging capabilities, has the ability to amplify benefits4
The most important DLT applications will require deep collaboration between incumbents,
innovators and regulators, adding complexity and delaying implementation5
New financial services infrastructure built on DLT will redraw processes and call into
question orthodoxies that are foundational to today's business models6
