Understanding Blockchain & Writing Smart Contracts in Etherium - Talk & Hands-on

Hi,

April edition of Sahaj DevDay is all about block chain. Event is packed with a talk and a hands-on. Here is the take away in brief :

1. Building crypto currency from scratch - components involved, consensus algorithms, cryptography required.
2. Talk on different consensus algorithms and contrast between them including PoW/PoS/PoC/PoB
3. Hands on - Writing smart contracts in Etherium

TODOs for the hands on session -

You will need to bring your laptop for the event. You will have to install the tools, clone the repo prior to the event.

Following are the pre-requisites for this hands-on workshop on Ethereum.

1. Since this is a hands-on workshop on writing code on Blockchain, it will help if the participants have explored the concepts of blockchain to some extent.
2. Bring your own device (Mac OSX/Linux would be ideal)
3. Software to install
   Install Nodejs - Version 8 (https://nodejs.org/en/)
   Install Truffle - npm install -g truffle
   Install Ganache (http://truffleframework.com/ganache/)
4. Kindly clone this repository to get the start up code for this session (https://github.com/sahajsoft/devday_blockchain/tree/devday_bangalore)

Note: This session will involve coding "smart contracts" using Solidity (https://solidity.readthedocs.io/en/develop/ - contract-oriented, high-level language for implementing smart contracts designed to target the Ethereum Virtual Machine) and writing the DAPP layer in Javascript. We will not be spending time on Javascript fundamentals in this session.
