2. What is a Blockchain network?
2
A set of nodes or peers …
... running a p2p
CONSENSUS protocol ...
... to maintain a common
record of transactions:
the BLOCKCHAIN

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:

Hyperledger: A Linux Foundation project
• A collaborative effort created to advance cross-industry
blockchain technologies for business
• Announced December 2015, now over 150 members
• Open source, open standards, open governance
• Five frameworks and three tools projects
• IBM is a premier member of Hyperledger

“A broad, cross-industry and open source approach is critical to
advance the potential for blockchain and make it mainstream. Even
beyond building out standards, creating common code will allow
organizations to focus on creating industry-specific applications that
enhance the value of this technology.”
Arvind Krishna, Senior Vice President and Director of IBM Research

Hyperledger Fabric: Distributed ledger platform
10
• An implementation of blockchain technology that
is a foundation for developing blockchain
applications
• Emphasis on ledger, smart contracts, consensus,
confidentiality, resiliency and scalability.
• V1.0 released July 2017
– 159 developers from 27 organizations
– IBM is one contributor of code, IP and
development effort to Hyperledger Fabric

Business Application
Hyperledger Composer
Blockchain (Hyperledger Fabric)
– A suite of high level application abstractions for business networks
– Emphasis on business-centric vocabulary for quick solution creation
– Reduce risk, and increase understanding and flexibility
– Features
– Model your business networks, test and expose via APIs
– Applications invoke APIs transactions to interact with business network
– Integrate existing systems of record using loopback/REST
– Fully open and part of Linux Foundation Hyperledger
– Try it in your web browser now: http://composer-playground.mybluemix.net/

Business Network definition

19. 19
– Domain specific APIs very attractive to mobile and web
developers. Resources and operations are business-
meaningful
– Composer exploits Loopback framework to create REST
APIs: https://loopback.io/
– Extensive test facilities for REST methods using loopback
– Secured using JS Passport, giving >400 options for
authentication
– Composer provides back-end integration with any
loopback compatible product
– e.g. IBM Integration Bus, API Connect, StrongLoop
– Outbound and Inbound (where supported by
middleware)
Systems of Record Integration

20. Open Governance
Anyone can join or contribute
Built from the ground up for enterprise
With a maturity model to help companies move to production
Performance
Supports up to 1000 tps*
Confidentiality and privacy
Built-in channels for isolation and membership services for signing and
encryption. Supports IBM Blockchain Platform.
Modularity and flexibility
Choice of consensus algorithms and programming languages

Smart Contracts leveraging IBM Operational Decision Manager
 Externalizing Smart Contract business logic in ODM
- Business decisions involved in Smart Contracts are delegated to the ODM rule engine
- eXecution Object Model generated from HyperLedger Composer Data Model
- Business stakeholders are maintaining the logic in ODM tools, like Decision Center
 Integrating ODM Rule Execution Server with Hyperledger Fabric
- Deploying Rule Execution Server in Blockchain peer nodes
- Calling Decision Services REST API from Hyperledger Composer Smart Contracts
- Deploying Ruleset through Blockchain transactions
