5. Introduction to Hyperledger
A global, cross-industry community of communities advancing business
blockchain technologies.
WHAT: Hyperledger is incubating and promoting enterprise grade, open source business blockchain
technologies, including distributed ledgers, smart contract engines, client libraries, graphical interfaces,
utility libraries, and sample applications.
WHY: Hyperledger provides the underlying open source software, on top of which anyone can set up apps
to meet business needs.
HOW: Built under technical governance and open collaboration, individual developers, service and solution
providers, government associations, corporate members and end users are all invited to participate in the
development and promotion of these game-changing technologies.

6. The Linux Foundation hosts many of
the most important open source
projects in the world, including Linux.
With more than 1,000 companies
backing tens of thousands of active
developers, our projects harness the
power of open source development to
fuel innovation at unmatched speed
and scale. Source: https://www.linuxfoundation.org/

10. Hyperledger Frameworks & Use Cases
Hyperledger Fabric: 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.
Hyperledger Iroha: A business blockchain framework designed to be simple and easy to incorporate into
infrastructural projects requiring distributed ledger technology.
Hyperledger Sawtooth: 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.
Hyperledger Burrow: A permissionable smart contract machine. The first of its kind when released in
December, 2014, Burrow provides a modular blockchain client with a permissioned smart contract
interpreter built in part to the specification of the Ethereum Virtual Machine (EVM).
Hyperledger Indy: 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.

11. Hyperledger Tools & Use Cases
Hyperledger Composer is a collaboration tool for building blockchain business networks, accelerating the
development of smart contracts and their deployment across a distributed ledger.
Hyperledger Cello aims to bring the on-demand “as-a-service” deployment model to the blockchain
ecosystem to reduce the effort required for creating, managing and terminating blockchains.
Hyperledger Quilt offers interoperability between ledger systems by implementing ILP, which is primarily a
payments protocol and is designed to transfer value across distributed ledgers and non-distributed ledgers.
Hyperledger Explorer can view, invoke, deploy or query blocks, transactions and associated data, network
information, chain codes and transaction families, as well as any other relevant information stored in the
ledger.
Hyperledger Caliper is a blockchain benchmark tool, which allows users to measure the performance of a
specific blockchain implementation with a set of predefined use cases.
