- 1. Code Camp: Hyperledger Tracy A Kuhrt, The Linux Foundation Community Architect, Hyperledger September 25, 2017
- 2. About Me 2 20+ years of software engineering and architecture experience ● The Linux Foundation ● PayPal ● Microchip Technologies Twitter: @TracyKuhrt email: tkuhrt@linuxfoundation.org
- 3. Agenda 3 1 What are Hyperledger and the Linux Foundation What projects exist under the Hyperledger umbrella2 Introduction to Hyperledger Composer3 Hyperledger Composer in action4
- 4. Open source collaborative effort to advance cross-industry blockchain technologies Hosted by The Linux Foundation, fastest-growing project in LF history Global collaboration spanning finance, banking, IoT, supply chains, manufacturing and technology Introducing Hyperledger 4
- 5. 5 We are helping global privacy and security through a program to encrypt the entire internet. Security Networking We are creating ecosystems around networking to improve agility in the evolving software-defined datacenter. Cloud We are creating a portability layer for the cloud, driving de facto standards and developing the orchestration layer for all clouds. Automotive We are creating the platform for infotainment in the auto industry that can be expanded into instrument clusters and telematics systems. Blockchain We are creating a permanent, secure distributed ledger that makes it easier to create cost-efficient, decentralized business networks. We are regularly adding projects; for the most up-to-date listing of all projects visit tlfprojects.org Web We are providing the application development framework for next generation web, mobile, serverless, and IoT applications. The Linux Foundation is Much More than Linux

Hyperledger Composer Hyperledger Explorer Hyperledger Cello Modules Typically built for one framework, and through common license and community of communities approach, ported to other frameworks Hyperledger Fabric Hyperledger Iroha Hyperledger Sawtooth HyperledgerCloudFoundry Node.js Open Container Initiative Hyperledger Modular Umbrella Approach 6 Infrastructure Technical, Legal, Marketing, Organizational Ecosystems that accelerate open development and commercial adoption Frameworks Meaningfully differentiated approaches to business blockchain frameworks developed by a growing community of communities Hyperledger Burrow Hyperledger Indy
- 8. Introduction to Hyperledger Composer 8 ● A suite of tools that allow you to ○ quickly model your business blockchain network ○ quickly generate REST APIs for interacting with your blockchain network ● Emphasis on business-centric vocabulary for quick solution creation Business Application Hyperledger Composer Hyperledger Fabric (Blockchain Framework)
- 9. Develop blockchain applications more quickly and cheaply High level abstraction makes it easier to iterate Hyperledger Composer Benefits 9 Move from business concepts to blockchain solution

- 11. Business Network is Defined using Four Files 11 Model File (.cto) Access Control (.acl) Script File (.js) Query File (.qry) Defines the structure and relationships between model elements. Defines the access rights of participants on the network. Implements the business requirements. Optional. Defines queries that return data about the blockchain world state.
