Ethereum

CRYPTOCURRENCY

Currency

  • Ether(ETH) is a cryptocurrency that runs on Ethereum network.

  • It is used to pay computational resources and transaction fees on the Ethereum network.

  • Peer to Peer Currency

Why Ether?

Need of Ether

  • Ether can be utilized for building decentralized applications, smart contracts, and making standard peer to peer payments.

  • It is used to pay for gas, a unit of computation used in transactions and other state transitions.

What is Smart Contract?

Smart

Contracts

  • A smart contract is a computer program that facilitates the exchange of money, shares and property.

  • Any user on the Ethereum network can create these contract.

  • Contains the terms and conditions of a mutually agreed contract betwen the peers

Key

Features

Primary features of a Smart contract

  • Once it is executed it cannot be altered.

  • Any transaction done on top of Smart contract is rejected totally making contract to be immutable.

  • Carried out among two anonymous parties without the need of central authority.

  • Provides transfer of any asset or currency in a trustworthy manner.

Ethereum Virtual Machine

Virtual

Machine

  • EVM is a virtual machine designed to operate as a runtime environemnt for ethereum based smart contracts

  • The developers code the agreement of smart contract using ethereum programming language and uploaded on EVM.

  • Operated in sandbox environment.

Working

Features of EVM

  • Any programming language in the smart contract is compiled by 'Bytecode'.

  • 'Bytecode' can be read and executed by Ethereum feature called EVM.

  • EVM guarantees security by preventing cyber attacks.

Decentralized Applications

DAPP

  • A Dapp consists of bunch of backend code and smart contracts that runs on a distributed P2P (Peer to Peer) network.
  • Imagine this as a decentralised version of web2 games where backend is replaced by blockchain.

Decentralized Autonomous Organization

DAO

  • Decentralized Autonomous Organization is a digital organization that aims to operate without the need of hierarchical management.

  • It exists on the block chain network where it is governed by its protocols and rely upon smart contracts.
