1. Blockchain & Brooklyn Distributed Ledgers and Smart Contracts with Apache Brooklyn and Hyperledger Andrew Donald Kennedy, October 2017
2. What is Blockchain The Hyperledger Project Available Distributions from Hyperledger Some Example Blockchain Use Cases Apache Brooklyn and Hyperledger Introduction @grkvlt
3. Blockchain A new kind of transactional database. @grkvlt
4. Blockchain? A new way of charging 10x as much for a transactional database. @grkvlt
5. Blockchain "Blockchain is a technology for a new generation of transactional applications that establishes trust, accountability and transparency while streamlining business processes." Or... "Blockchain is a distributed, cryptographically secure ledger of transactions." @grkvlt
6. Blockchain "A blockchain is a fully-distributed, peer-to-peer software network which makes use of cryptography to securely host applications, store data, and easily transfer digital instruments of value that represent real-world money. " — Dannen, Chris; Introducing Ethereum and Solidity; DOI 10.1007/978-1-4842-2535-6_1 @grkvlt
7. Blockchain Overview @grkvlt
8. Blockchain Properties Transactions Security Privacy Reliability Resilience @grkvlt
9. Blockchain Use Cases @grkvlt
10. Hyperledger
11. The Hyperledger Project is a collaborative effort created to advance Blockchain technology by identifying and addressing important features for a cross- industry open standard for Distributed Ledgers that can transform the way business Transactions are conducted globally. Hyperledger Fabric @grkvlt
12. • Open Source • Originally IBM Blockchain • Graduated to become first Hyperledger Foundation Incubator project • Linux Foundation Collaboration Hyperledger Fabric @grkvlt
13. Hyperledger’s Modular Umbrella Approach Tools Typically built for one framework, and through common license and community of communities approach, ported to other frameworks Hyperledger Indy Hyperledger Fabric Hyperledger Iroha Hyperledger Sawtooth Hyperledger Burrow Hyperledger CloudFoundry Node.js Cloud Native 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 from the entire industry Hyperledger Composer Hyperledger Explorer Hyperledger Cello @grkvlt
15. Hyperledger Fabric Hyperledger Burrow Hyperledger Sawtooth Monax Hyperledger Cello and Composer Hyperledger Distributions @grkvlt
16. Brooklyn Blockchain Blueprints Hyperledger Fabric 1.0 Framework Hyperledger Burrow Framework Hyperledger Sawtooth Framework Blockchain Asset Management Application Blockchain Certificate Authority Smart Contract Deployment @grkvlt
17. Cloudsoft Blockchain Service • Deploy Hyperledger Frameworks to virtually any environment • Currently Hyperledger Fabric included in AMP • Hyperledger Burrow and Sawtooth in progress • Let developers focus on creating Chaincode or Smart Contracts, not the infrastructure and plumbing • Accelerate Time to Value for enterprises interested in Blockchain • Cloudsoft Blockchain Service is available via the IBM Marketplace • Cloudsoft is a Founder Member of the IBM Blockchain Ecosystem and a member of the Hyperledger Foundation @grkvlt
18. Blueprints
19. Cloudsoft Blockchain Service @grkvlt
20. • Identity • Privacy • Confidentiality • Auditability Hyperledger Fabric @grkvlt
21. Hyperledger Application Fabric The Hyperledger Application Fabric is a group of Clusters of Docker Engines spread across different regions, giving a global deployment that can be easily scaled and extended. Hyperledger components are Docker containers providing Blockchain services. @grkvlt
22. Hyperledger and Kubernetes With the current popularity of Kubernetes as a container platform, it would be very useful to be able to deploy Hyperledger there. Kubernetes Pods are the unit of deployment for containers, and are defined as YAML resource files. The Cloudsoft AMP Container Service allows deployment of these Kubernetes resources, and we are in the process of developing Pods for the Hyperledger components. This feature will be part of the next release of the Cloudsoft HLF in AMP 5.0. @grkvlt

30. Simple Blueprint Extract the essential components from the previous architecture diagram: 1. Web Application • Node.js Server and Redis Store 2. Chaincode (or Smart Contract) • Reducing Complexity • Simple Brooklyn concepts • Dozen lines of YAML… @grkvlt

38. Hyperledger Sample Application We can demonstrate an asset management Chaincode application that spins up a Non-Validating Peer in a Docker container, deploys the Chaincode onto the Validating Peer Cluster and then performs the following Transactions: 1. Assigns an asset to Alice 2. Transfers to Bob and verifies ownership 3. Transfers to Charlie and verifies ownership 4. Transfers to Dave and verifies ownership @grkvlt
