The document provides an overview of the Hyperledger community update and blockchain frameworks. It summarizes that Hyperledger is an open source collaborative effort hosted by The Linux Foundation to advance blockchain technologies across multiple industries. It then provides details on the various Hyperledger frameworks such as Fabric, Sawtooth, Iroha, Indy, and Burrow. It also summarizes the business blockchain tools under Hyperledger like Composer, Cello, Explorer, and Caliper. The document outlines the leadership and global community engagement efforts around Hyperledger.

Blockchain allows multiple different parties to securely
interact with the same universal source of truth
Streamlined settlement,
improved liquidity,
increased transparency
and new products/markets
Finance
Unite disparate processes,
increase data flow and
liquidity, reduce costs and
improve patient
experience and outcomes
Healthcare
Track parts and service
provenance, ensure
authenticity of goods,
block counterfeits, reduce
conflicts
Supply Chain

5. 5
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:

7. 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
7

8. 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
8

9. Hyperledger Iroha
Business Blockchain Framework
● Contributed by Soramitsu, Hitachi, NTT Data and Colu
● Written in C++
● Emphasis on mobile application development
● Provides both Android and iOS SDKs
9

10. Hyperledger Indy
Business Blockchain Framework
● Contributed by the Sovrin Foundation
● Focuses on identities rooted on blockchains
● Utilizes zero-knowledge proofs to provide verifiable claims
● These verifiable claims can be used to prove something about the identity
without providing access to the underlying data
10

11. Hyperledger Burrow
Business Blockchain Framework
● Contributed by Monax
● First permissioned ledger with support for the Ethereum Virtual Machine (EVM)
● Originally named ErisDB
● Uses Tendermint as its consensus mechanism
11

12. Hyperledger Composer
Business Blockchain Tool
● Contributed by IBM and Oxchains
● Suite of tools to quickly develop your blockchain business networks
● Modeling language allows you to have your business people specify the
participants, assets, and transactions
● Developers write transaction logic in JavaScript
● Ability to generate a REST API and Angular application from the model
12

13. Hyperledger Cello
Business Blockchain Tool
● Contributed by IBM, with sponsors from Soramitsu, Huawei and Intel
● Used for DevOps
● Allows you to quicly deploy your blockchain networks
● Provides the ability to monitor your blockchain networks
● Blockchain network can be deployed on baremetal, virtual machine, or cloud
13

14. Hyperledger Explorer
Business Blockchain Tool
● Originally contributed by IBM, Intel and DTCC. Recent release contributed by
OneChain
● Allows you to visualize the blockchain
● Blocks
● Transactions
● Network information
● Chaincodes or Transaction families
14

15. Hyperledger Quilt
Business Blockchain Tool
● Contributed by NTT Data and Ripple
● Java implementation of the Interledger protocol
● Interledger protocol provides:
● atomic swaps between ledgers (even non-blockchain or distributed ledgers)
● a single account namespace for accounts within each ledger
15

16. Hyperledger Caliper
Business Blockchain Tool
● Contributed by Huawei
● Blockchain benchmark framework to provide metrics of various performance
indicators such as:
● TPS (Transactions Per Second), transaction latency, resource utilization, etc
● Currently supports: Fabric, Sawtooth, Iroha
● Works in close collaboration with Performance and Scalability WG
