This session will explore how Blockchain technology can solve the 4 major pain points in financial technologies: High maintenance and support costs, Out-dated IT systems, Need for manual reconciliation and Systems that don’t “talk” to each other. Main points covered: • What Is Blockchain technology? • What Blockchain technology can do? • What Blockchain technology cannot do? • Anatomy of a Blockchain solution • Ideal Blockchain use cases for banks Presenter: Our presenter for this webinar is Rohas Nagpal, is a Blockchain evangelist and Chief Blockchain Architect of Primechain Technologies Pvt. Ltd. Rohas comes from a cybercrime investigation and security background and has been working in that field since the mid-1990s. He co-founded Asian School of Cyber Laws in 1999 and has investigated cybercrimes & data breaches for hundreds of organizations across most industry and Government sectors. He has assisted the Government of India in framing draft rules and regulations under the Information Technology Act. Organizer: Ardian Berisha Date: April 18th, 2018

2. Financial markets & institutions rely very heavily
upon technology for every part of their
business. Current pain-points in financial
technologies:
1. High maintenance and support costs
2. Out-dated IT systems
3. Need for manual reconciliation
4. Systems that don’t “talk” to each other
The problem

3. 1. A blockchain is a peer-to-peer network that timestamps
transactions by hashing them into an ongoing chain of
hash-based proof-of-work. Blockchain is the technology
on which the Bitcoin crypto-currency runs.
2. Blockchain is an innovative mix of decades old, tried
and tested technologies including Public key
cryptography (1970s), Cryptographic hash functions
(1970s) and Proof-of-work (1990s).
3. Blockchains are provably immutable and enable the
rapid transfer and exchange of crypto-tokens (which can
represent assets) without the need for separate
clearing, settlement and reconciliation.
What is blockchain technology?
Distributed
Ledger
Technology
Blockchain
All blockchains are distributed ledgers.
All distributed ledgers are not blockchains.

4. 4. Blockchain technology can enable excluded people to
enter the global economy, protect the privacy of
participants, allow people to "monetize their own
information", and provide the capability to ensure
creators are compensated for their intellectual property.
5. Multichain is one of the most popular blockchain
frameworks.
6. Blockchain solutions can be:
• Permissioned (only selected entities can connect).
Permissioned blockchains can be private (one entity
controls all the nodes) or shared (multiple entities
control nodes)
• Permissionless (any entity can connect)
What is blockchain technology..?
Permissioned
Private Shared
Permission-less

Why blockchain?
Higher Security
Lower cost
Transparency
Automated reconciliation

By storing data across its network, a blockchain eliminates
the risks that come with data being held centrally.

Blockchain removes the characteristic of infinite reproducibility
from a digital asset. It confirms that each unit of value was
transferred only once, solving the long-standing problem of
double spending.
A blockchain can assign title rights because it provides a
record that compels offer and acceptance.
A blockchain lacks centralized points of vulnerability that
hackers can exploit. It has no central point of failure.

11. The transaction metadata (e.g.
invoices) are stored in encrypted
form using Advanced Encryption
Standard (AES). The AES
decryption keys are generated at
the creators end.
Addresses, assets and transaction
amounts are stored in all admin,
mining and member nodes in
unencrypted form.
Systems for off-chain and off-line
private key generation, private key
storage and transaction signing are
available.
Platform for secure messaging
(with encryption and digital
signatures).
Data privacy & security
