Creating software to handle risky or sensitive applications is hard. Creating an environment that your systems’ users will trust is even harder. Blockchain is a technology that can provide security and trustworthiness through aspects like decentralization, immutable transactions and transparency.

The session is split into a 1 hour talk, followed by a 3 hour hands-on workshop. The facilitator walks attendees through an introduction of blockchain, comparisons with bitcoin, breaks some myths about bitcoin and blockchain, and throws light on a number of currently implemented examples of blockchain usage. Attendees then move on to setting up and beginning to work through creating a trustworthy, secure voting system using blockchain and the Ethereum development platform.

Attendees will leave this workshop with a solid appreciation for the value of decentralized systems, and an understanding of how to create a basic application. The hands-on aspect of this workshop help drive these learnings home via practical exercises and collaboration throughout the day.

This is the slide-deck (https://speakerdeck.com/abhi12ravi/blockchain-basics-workshop-at-sit-tumkuru) I've used at last week's blockchain basics workshop for college kids at India.

Hands-on workshop
An ubuntu image containing required packages will be shared with participants before hand. They can use VirtualBox to run it on their machines.
Agenda:
1. Setup development environment - Install ganache-cli, web3js and start test blockchain
2. Smart contracts: Use solidity (an object-oriented programming language) to write out a simple contract that increments votes and returns the count of votes
3. Setup a simple website to invoke the contract methods
4. Play with the application and see blockchain in live

Here's the tutorial (https://github.com/abhi12ravi/blockchain-vote) we followed to build the sample voting app.
