This document provides an overview of Hyperledger, an open source collaborative effort to advance cross-industry blockchain technologies. It discusses how blockchains and distributed ledgers can increase efficiency in business networks by providing consensus, provenance, immutability and finality. Hyperledger consists of several blockchain frameworks and tools developed by a growing global community to solve problems in industries like supply chains, healthcare, and finance.

2. 2
Business networks, wealth and markets
• Business Networks benefit from connectivity
– Participants are customers, suppliers,
banks, partners
– Cross geography and regulatory boundary
• Wealth is generated by the flow of goods and
services across business network in transactions
and contracts
• Markets are central to this process:
– Public (fruit market, car auction), or
– Private (supply chain financing, bonds)

3. 3
Ledgers are key
Ledgers are THE system of record for a business.
Businesses will have multiple ledgers for the multiple
business networks in which they participate.
• Transaction: an asset transfer onto or off the ledger
– John gives a car to Anthony (simple)
• Contract: the conditions for a transaction to occur
– If Anthony pays John money, then car passes
from John to Anthony (simple)
– If car won't start, funds do not pass to John (as
decided by third party arbitrator) (more complex)

Other types of blockchain exist
– The first blockchain application
– Defines an unregulated shadow-currency
– Resource intensive
• Blockchains for business are generally permissioned
and private, and prioritize:
– Identity over anonymity
– Selective endorsement over proof of work
– Assets over cryptocurrency
is an example of an
unpermissioned, public ledger:

What?
• Track diamonds across supply chain from mine to retail
How?
• Shared ledger for storing digital certification with
supporting material
Benefits
• Protect against the occurrence of fraud, theft, trafficking
and black markets
• Assist in the identification and reduction of synthetic
stones being labelled as authentic
• Increase speed of transparency for cross border
transactions for insurance companies, banks and
claimants
Legitimize Diamonds and Reduce Fraud

8. 8
What?
• Provide a trusted source of information and traceability to
improve transparency and efficiency across the food
network.
How?
• Shared ledger for storing digital compliance
documentation, test results and audit certificates network.
Benefits
• Reduce impact of food recalls through instant access to
end-to-end traceability data to verify history in the food
network and supply chain.
• Help to address the 1 in 10 people sickened and 400,000
fatalities WW which occur every year from food-born
illnesses.
Food Safety

9. 9
What?
• Ninety percent of goods in global trade are carried by the ocean
shipping industry each year. Costs associated with trade
documentation processing and administration are estimated to be
up to one-fifth the actual physical transportation costs.
How?
• A new blockchain solution from IBM and Maersk will help manage
and track the paper trail of tens of millions of shipping containers
across the world by digitizing the supply chain process.
Benefits
1. Enhance transparency and the highly secure sharing of
information among trading partners and customs officials.
2. Reduce fraud and errors, reduce the time products spend in the
transit and shipping process, improve inventory management
and ultimately reduce waste.
3. Potential to save the industry billions of dollars.

Together with the global technology community, The Linux Foundation® is solving the world’s
hardest problems through open source and creating the largest shared technology
investment in history.
With 16 years experience providing governance structure, IT infrastructure and
ecosystem development, The Linux Foundation is the umbrella organization for more than
60 open source projects accelerating open technology development and commercial
adoption.
Some of the game-changing initiatives hosted by The Linux Foundation include:

13. Hyperledger Fabric
Business Blockchain Framework
● Hyperledger’s first project, contributed by IBM and Digital Asset
● Smart contracts called “chaincode” are written in Golang (and with 1.1
Javascript) and run in secure Docker containers
● Channels ensure that only the participants involved in a transaction see the
transaction
● First project to reach ‘Active’ status and to release version 1.0
● 159 contributors from 27 organizations, 3500 change sets
13

14. Hyperledger Sawtooth
Business Blockchain Framework
● Hyperledger’s second project, contributed by Intel
● Second project to reach 1.0 maturity
● Supports both permissioned and permissionless deployments
● Includes a novel consensus algorithm, Proof of Elapsed Time (PoET), which
mimics proof of work without the high energy consumption using the secure
enclave on an Intel chip to provide a random wait timer to each of the
validators (nodes) on the network
● Supports the EVM through a collaboration with the Hyperledger Burrow
community
14

15. Hyperledger Iroha
