4. What is common element in each agreement?
TRUST

5. Ways to create trust across organizations
Intermediaries1 Manual verification2
• Increases total cost (transaction cost)
• Adds complexity to business process
• Reduces direct contact between
parties
• Increases total cost (human
resources)
• Is more prone to errors
• It usually takes time to ensure that
records are complete and accurate

6. The ledger can only be updated by
network consensus
Data is distributed and shared to
multiple parties
Data is securely stored in a ledger
—the records are digitally signed
The information is cryptographically
immutable – single source of truth
What if… we count on a secure, shared
distributed ledger

9. Multiple Consensus Algorithm Types
These are just a few examples… the future is pluggable consensus algorithms
Proof of Work
Proof of StakeVoting
Proof of
AuthorityThe Proof-of-Work (PoW)
method asks users to
repeatedly run hashing
algorithms or other client
puzzles, to validate
electronic transactions in
exchange for the
opportunity of a reward.
In Proof of Stake (PoS)
based blockchains the
creator of the next block is
chosen in a deterministic
(pseudo-random) way, and
the chance that an account
is chosen depends on its
wealth (i.e. the stake).
“Voter” nodes can vote on
which block should eb the
canonical head at a
particular height.
The most recent block with
the most votes is
considered the canonical
head of the chain. A block is
only considered valid once
a given threshold of votes
has been received from
valid voters.
Proof-of-Authority (PoA)
uses a hard-configured set
of "authorities" - nodes that
are explicitly allowed to
create new blocks and
secure the blockchain. This
makes it easier to maintain
a private chain and keep
the block issuers
accountable.

12. Customers Success Stories using Blockchain

13. Challenge
• One in six people worldwide live without
legal documentation, striping them access
to critical services like voting, healthcare,
housing, banking, and education
• Without means of identification, refugees
and asylum seekers face detention upon
arrival in a country
Strategy
• Microsoft has partnered
with Accenture to develop a
blockchain-based digital
identity system, combined
with biometrics to help
government agencies
• Establish digital identity,
securely registered on a
distributed ledger
Results
• The blockchain solution is used by the United
Nations High Commissioner for Refugees
which has enrolled more than 1.3 million
refugees in 29 countries
• Agencies can verify identity and interoperate
across systems to provide services
• Verifying identity means refugees can become
productive members of society more quickly

Blockchain for royalty payments
Challenge
• Microsoft used a complicated, manual
method to calculate royalties for XBOX
publishers.
• Microsoft’s royalty process took 45 days,
which delayed payments to publishers.
Strategy
• Microsoft developed a
blockchain-based solution
that offers XBOX royalty
information in near real
time.
Results
• Blockchain technology improved trust by
making the royalty payment calculation
process more transparent for publishers.
• Publishers gained actionable business insights,
enabling them to proactively respond to
customer demand.
• Blockchain technology reduced XBOX process
efforts by two thirds and saved publishers
time by eliminating the need for manual
audits.

Using blockchain to share coffee’s journey with
customers
“While high-quality, handcrafted beverages are so important, it’s the stories, the people, the connections, the
humanity behind that coffee that inspires everything we do. This kind of transparency offers customers the chance
to see that the coffee they enjoy from us is the result of many people caring deeply”
— Michelle Burns, Starbucks senior vice president of Global Coffee & Tea

20. “Every coffee has a story to tell, and I
could not be more excited for people to
be more connected to the whole coffee
experience, from bean to cup, and meet
the many people whose hard work,
time and attention makes coffee
possible,”
Michelle Burns
Starbucks’ senior vice president, Global Coffee,
Tea and Cocoa.
