TRUST
The Deciding Factor
in Whether a Society Can Function

Put you logo

The 2019 Edelman Trust Barometer, an annual survey of
33k people in 27 markets, reveals that there is still
distrust in several markets and for speciﬁc organizations,
namely in Government and Media institutions.
The Need for Trust

The onus is on businesses to prove that it is possible to
act in the interest of shareholders and society alike.
To show that free markets can succeed for all if
businesses work with the people.
Without trust, the system fails

The way internet technologies tend
to get developed is a partnership
between three organizations:
standards, global governance and
implementors, like Hyperledger.
The Trust Protocol

About Hyperledger

The Hyperledger “Greenhouse”

Put you logo

Intended as a foundation for developing applications
or solutions with a modular architecture, Hyperledger
Fabric allows components, such as consensus and
membership services, to be plug-and-play.

Put you logo

Tools, libraries, and reusable components for
providing digital identities rooted on blockchains or
other distributed ledgers so that they are
interoperable across administrative domains,
applications, and any other silo.

Put you logo

A modular platform for building, deploying, and
running distributed ledgers. Hyperledger Sawtooth
includes a novel consensus algorithm, Proof of
Elapsed Time (PoET), which targets large distributed
validator populations with minimal resource
consumption.

The Challenge
Provide patients' with more control over their
healthcare information and who it is shared
with.
The Technology
Hyperledger Fabric

“We looked at a bunch of private protocols, but with so many diﬀerent
payers and providers on our network, convincing everyone to buy the same
software stack from the same vendor would be very challenging. Not only
does open source leverage the great work of many people, it also makes
that adoption easier.”
— Aaron Symanski, CTO of Change Healthcare

The Challenge
Unnecessary red tape costs are troublesome
for both governments and the industry.
The Technology
Hyperledger Indy
Government Red Tape 1/3
Goal
Assemble an open software stack that helps
business people establish trusted digital
relationships to help governments cut red
tape.
Additional Outputs
- Like-minded groups to share development
- Establish a common ground for the problem

“This can help streamline any process that involves trust. (…) The VON team
contributed the code for the enterprise wallet back to Hyperledger—proof
that the “open by default” approach works well for governments. (…)
We see the proper place for our code is with an open-source organization
with the stability and good governance of the Linux Foundation,”
— John Jordan, Product Lead at the BC Government

The Challenge
When an outbreak of a food-borne disease
happens, it can take days, if not weeks, to find
its source. Better traceability could help save
lives by allowing companies to act faster and
protect the livelihoods of farmers by only
discarding produce from the affected farms.
The Technology
Hyperledger Fabric
Food Supply Chain 1/3
Additional Outputs
- Trace the origin of 25 products from 5
different suppliers
- IBM Food Trust

“The Hyperledger Fabric blockchain-based food traceability system built for
the two products worked. For pork in China, it allowed uploading certiﬁcates
of authenticity to the blockchain, bringing more trust to a system where
that used to be a serious issue. And for mangoes in the US, the time needed
to trace their provenance went from 7 days to… 2.2 seconds!”
— Frank Yiannas, former VP of Food Safety at Walmart
