Reading Time: 9 minutes

The workshop was intended to excite and inspire some of the minds to set into brain-storming that might help the audience to come up with innovation with 21 st century internet Magnus, BLOCKCHAIN, to solve the real-world problems.

The prerequisite was null and void but an audience with a little bit of patience and curiosity, which certainly the audience was!

The workshop was segmented into two halves. It started with non-technical points to get launched into the topic and later shifted to tech-based. Key points of the talk were:

Intuitive questions like why blockchain, what are the daily life problems that are needed to be addressed through blockchains, how blockchains can solve the crisis of current internet like data tampering and data breaching was answered to create the vacuum in audience minds for the talk.
The talk then moved to introduce the audience with basic key terminologies like cryptography, hashing, mining, genesis block, ledger, nodes, consensus, etc.
Very carefully the backbones of the blockchain were introduced. The network design concept that gives this technology the key power were: a) Distributed system and b) Decentralized systems. How the Blockchain provides architectural and political decentralization and logical centralization was deeply discussed.
All of these gives the blockchain major characteristic system advantages of attack and collusion resistance, fault tolerance, good scalability, etc.
Finally, the real world application of the blockchain was explained and vividly demonstrated. The successful digital currency of Bitcoin, how it solved the major two unsolved problems of its time- malicious activity prevention and the double spending, how it works and some of its basic underlining stories were discussed.
The workshop ended with the display of a few of the projects that instructors made to participate in various hackathons.

Here is the ppt used in the actual workshop. All the references and important links would be uploaded soon, stay tuned!!!!

MetaMask

The most used chrome extension wallet and Web 3 provider that allows users to interact with decentralized applications.

Smart Contract Languages

If you’re developing on Ethereum, you’re going to need to know how to write smart contracts. Luckily there are not too many different languages that you need to know. Solidity the main smart contract language is easier to learn if you already possess a good understanding of Javascript.

Solidity

An object-oriented, high-level language for implementing smart contracts.

Vyper

A pythonic programming language for implementing smart contracts. Vyper is also currently beta software.

IDEs/Editors

IDE stands for Integrated Development Environment. IDEs and Editors are what you need to write and test software. They are software suites that consolidate basic tools that are required to start writing on Ethereum. Below are the most popular IDEs and Editors.

Atom

An open source and usable text editor.

Remix

A suite of tools to interact with the Ethereum blockchain in order to debug transactions.

Visual Studio Code

Visual Studio Code extension that adds support for Solidity.

Public Testnets

Public Testnets on Ethereum offer a way for developers to test what they build without putting their creations on the main Ethereum network. Developers are able to obtain as much ETH as you want on testnets because testnet ETH doesn’t carry any monetary value. Below are the most used testnets to start testing on and the links for where you can request testnet ETH.

Ropsten

A proof-of-work blockchain that most closely resembles Ethereum and allows you to easily mine faux-Ether.

Görli

Proof-of-authority cross-client testnet, synching Parity Ethereum, Geth, Nethermind, Pantheon, and EthereumJS. This testnet is a community-based project, completely open-source.

Kovan

A proof-of-authority blockchain started by the Parity team. Test ether must be requested.

Rinkeby

A proof-of-authority blockchain started by the Geth team. Test ether must be requested.

Local Testnets

Similar to Public Testnets, Local Testnets are a place for you to test your software without pushing it public. Unlike Public Testnets, the Local Testnet software will only run on your computer/node and other users won’t be able to see it or interact with it.

Ganache

Ganache is a personal blockchain for Ethereum development that developers can use to deploy contracts, develop applications, and run tests.

Ganache CLI

Fast Ethereum RPC client for testing and development. The command line version of Ganache, your personal blockchain for Ethereum development.

Front–End Interfaces

If you want to start developing dapps, you’ll need front-end development skills. Below are the most popular front-end interfaces that will help you turn your dapp from an idea to a live Ethereum mainnet application.

Web3.js

An Ethereum JavaScript API which connects to the Generic JSON RPC specification. A local or remote Ethereum node must be run to use this library.

Ethers.js

Ethereum wallet implementation and utilities in JavaScript.

Drizzle

A collection of front-end libraries that make writing decentralized application frontends easier and more predictable. Drizzle provides a Redux library to connect a frontend to a blockchain.

Backend Interfaces

If you want to graduate from just building dapps, you’ll need to start learning and using the backend interfaces listed below. If you’re interested in doing backend/protocol work on Ethereum, you should have significant experience with Go, Rust, Java, .NET, Ruby, or Python. Explore some of the most frequently used backend interfaces below.

Web3.py

A Python implementation of Web3.js.

Nethereum

A .NET integration library for Ethereum allowing users to interact with Ethereum clients like Geth or Parity using RPC.

Web3j

A lightweight Java and Android library for integration with Ethereum clients.

Smart Contract Library

You’ve probably used programming libraries before, and these are no different. A smart contract library is the reusable piece of code for a smart contract which is deployed once and shared many times. Below are the most used smart contract libraries.

OpenZeppelin

A library that provides implementations of standards like ERC20 and ERC721 as well as Solidity components to build custom contracts.

Dappsys

A collection of building blocks for building smart contract systems written in Solidity.

Smart Contract Testing and Deployment

If you are creating a tool, product, or application on Ethereum, you’ll want to make sure your smart contract is in working order before deploying to the mainnet. These tools will help you build, test, and ship your code.

Truffle Suite

The most popular smart contract development, testing, and deployment framework. The Truffle suite includes Truffle, Ganache, and Drizzle. Read a d eep dive on Truffle.

Waffle

Waffle is a library for writing and testing smart contracts. Waffle is based on ethers.js.

Embark

A framework that allows you to easily develop and deploy decentralized applications. Currently integrates with EVM blockchains (Ethereum), IPFS, Swarm, Whisper, and Orbit.

Ethereum Clients

An Ethereum client refers to any node that is able to parse and verify the blockchain, its smart contracts, and everything in between. An Ethereum client also provides interfaces to create transactions and mine blocks which is the key for any Ethereum transaction. Below are the most popular Ethereum clients.

PegaSys Pantheon

Pantheon is an open-source Ethereum client developed under the Apache 2.0 license and written in Java.

Parity

An Ethereum client developed by Parity Technologies using the Rust programming language.

Geth
