A quick overview on Blockchain and how this technology will help in bringing the trust in a decentralized network. This was presented in IASA eSummit: http://iasaglobal.org/june-2016-esummit/

1. Let the trust evolve itselfin a decentralized network of inter-connected systems….

2. “We” & Trust” - in our day to day life
• We trust our family because we know they will be with us whenever we need
• We trust banks because we know our money is safe with them
• We trust our doctor because we know he cares about our health & suggest the
right medicine for us
• We trust commodity brands because we believe they are made of good quality
• We trust govt. and pay tax because we believe our tax money will be utilizing
for society welfare and country growth.

3. But what if
• Someone breach our trust
• Someone makes fraud and cheat us
• Someone steal our hard work and we are not get paid for our own creativity
• Charge huge premium just for the sake of trust
Its painful… really painful….

4. If not everything, but most of our day to day
life, we have to Trust “someone” for
managing our needs and providing services…
• Investments
• Savings
• Retirement planning
• Land registration
• Notary services
• Buying & Selling
• And lots more….
Trusted
Third Parties

5. Let’s talk about transactions, role of intermediaries &
The existence of “Trust”
Transfer Money
Option 1: Peer to Peer Cash transactions
Considerations:
- Any one to any one means locally distributed
- Mutual Trust for the value of transactions
- Anonymous & Private
- No middleman required
- Quick and Fast
- Not Scaled (many to many)
- Self risk management
- Not feasible in today’s world at scale.

6. Let’s talk about transactions, role of intermediaries &
The existence of “Trust”
Transfer Money
Option 2: Electronic transactions
Considerations:
- Requires 3rd party to bring trust
- The more complex flow, the more 3rd party involvement
- Costly as every party may charge some fees
- Slow Speed
- Examples: Paypal or Banks
- Confidentiality is with 3rd parties database
Trusted 3rd parties
as Intermediary
Services
Centralized | Closed | Private | Isolated

7. “Trusted Third Parties” and “Trust”
“As standards for trustability continue to rise, the
companies, brands, and organizations shown to lack
trustability will be punished more and more severely.”
https://hbr.org/2012/07/trust-in-the-age-of-transparency
“Untrustable business models thrive in our economic system today largely
because being untrustable can be highly profitable—in the short term
anyway—and many businesses are managed almost entirely for short-
term results.”

8. 2009 was the year of
financial crisis when..
People lost Trust
in Trusted Third Parties
(like banks, govt. fin.
institutions etc.)
And that also leads us to do retrospective at a larger scale…

9. Decentralized Payment System - Someone brought the idea of
Bitcoin…
• Peer to peer transactions and interactions
• Without financial institutions
• Cryptographic proof instead of central “Trust”
• Put “Trust” in the network (evolve itself)
instead of in a central institutions

Block is a group of multiple
transactions
Blocks are created by nodes over the network also
called ‘Minors’ and attached to previous blocks
Like in any distributed systems, sometimes participants
may disagree on the state of the ledger and may have
different version of transactions
The conflict is resolved and consensus is
formed on a single version of the ledger

12. The Internet
“The Internet has No Centralized Governance in
either technological implementation or policies for
access and usage; each constituent network sets its
own policies….”
Openness Decentralized Collaborative
Common Set of Rules agreed by majority
Objective to share information

BLOCKCHAIN NATIVE APPS
BLOCKCHAIN HYBRID APPS
• Trust in a trustless network
• Open Network Secure Access
• Open Source
• No SPOF / Redundancy
• Disruptive
• Speed / Real Time
• WORM Compliant /Safekeeping
• Decentralized
• Anonymity
Blockchain SDK / APIs
From “Internet of Information” to “Internet of Value”

14. Blockchain – Some core concepts
• Nodes
• Consensus Mechanisms
• Proof of Work (PoW)
• Proof of Stake (PoS)
• Zero Knowledge Proof (ZKP)
• Practical Byzantine Fault Tolerance (PBFT)
• Permission-less (Public) Vs Permissioned (Private or Consortium)

15. Blockchain – how it is progressing..
Blockchain1.0
• Currency
Blockchain2.0
• Smart
Contracts
Blockchain3.0
• Decentralized
Apps
Major focus is on
cash/payment transfer;
e.g. Bitcoin and lot more…
Brining the business logic into
Blockchain
Already implemented by large
Financial hubs using beyond
cash transactions
Completely new paradigm to
build the complete ecosystem
and build Apps on top of
blockchain platform
e.g. Etherum looks promising
2012 2016
and beyond
