Blockchain-The Internet’s New Magnum Opus

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:

  1. 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.
  2. The talk then moved to introduce the audience with basic key terminologies like cryptography, hashing, mining, genesis block, ledger, nodes, consensus, etc.
  3. 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.
  4. All of these gives the blockchain major characteristic system advantages of attack and collusion resistance, fault tolerance, good scalability, etc.
  5. 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.
  6. 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!!!!

What is the Ethereum Developer Portal?

It’s a place to get started and find the tools you need to develop and build applications on Ethereum.

Table of Contents

 


Are You a New Developer to the Ethereum Ecosystem?

Below is a mix of the main infrastructure tools and knowledge centres that will teach you how to build software on Ethereum. We recommend taking a look through the portal and reading about all the developer tools and options before getting started.

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

Solidity

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


ezgif.com-gif-maker

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_editor_logo

Atom 

An open source and usable text editor.


remix

Remix 

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


ETHEREUM-ICON_Black_small

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

Ropsten

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

Görli

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

Kovan

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


Rinkeby

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.





G Truffle

Ganache 

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


ganache-cli-128x128

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.





web3js

Web3.js

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.
