This event walks through how blockchain technology works with a live demonstration of an actual blockchain with a smart contract implemented in HyperLedger Fabric.

People have shared information in the same ways for hundreds of years: paper was simply replaced by digital computers. In both cases, information is still copied.

Blockchain technology has the potential to fundamentally disrupt this through efficiency and cost savings. This event will walk through how blockchain technology works.

• Why Blockchain?
• How It Works
• Distributed Computing and Data Sharing Architecture
• Append-Only Data Store
• Hashing
• Basic Transaction Data Structure
• Basic Block Structures
• Merkle Tree
• Merkle Root
• Smart Contracts
• Permissioned Blockchains
• Demonstration of a Blockchain implemented in HyperLedger
• Demonstration of enterprise web applications interacting with the Blockchain

So how does a blockchain keep transactions secure and the system in balance and healthy? The best way to discuss this question is to dig into the technical specifics of building an actual blockchain with code. 

For hands-on learning, we will reference the companion projects found on the official Keyhole Software GitHub via the following links:

• Java Blockchain Companion Project https://github.com/in-the-keyhole/khs-blockchain-java-example
• C# Blockchain Companion Project https://github.com/in-the-keyhole/khs-blockchain-csharp-example

This presentation demonstrates building a blockchain smart contract with HyperLedger.

Blockchain smart contracts ensure that agreements are verifiable, permanent, and coded to meet the terms of its parties - without the expense of a middleman. The smart contract executes the instructions consistently and without fail, perhaps enacted based upon a time-based or condition-based trigger.

Smart contract protocols potentially strengthen up the legal standing of contracts, which makes them extremely applicable to enterprise needs.

HyperLedger Fabric is an open source, permissioned blockchain foundation protocol for enterprise use. It is a distributed ledger solution, underpinned by a modular architecture designed to support pluggable implementations of different components, including configurable consensus and membership services.

Many technical presentations simply talk about the benefits of automation and DevOps through bullet point concepts, diagrams, and discussion.

In contrast, this presentation demonstrates the automation of a container-based application on a Kubernetes platform. We will discuss and demonstrate some of the key components and considerations of a DevOps enabled environment.

We walk through a tangible reference implementation to demonstrate the following:

• Ansible-based deployment automation
• Pipelining
• Automated Testing
• Quality Analysis
• Continuous Deployment
• Application Health
• Monitoring and Alerts

The reference application is microservice based (but most of the concepts apply to any application architecture), using Java and Spring Boot/Cloud, and will be deployed in an OpenShift cluster.

RedHat's OpenShift will be used as the Kubernetes distribution, however, that is not the main emphasis of the presentation. The principles discussed are applicable to cloud enablement on any platform.
