Let's start this Ethereum for beginners tutorial with introduction of Ethereum:
Ethereum is an open-source operating system that offers smart contract functionality. It is a distributed computing platform that supports developing decentralized Digital Applications (DApps) using blockchain technology. Ethereum provides a decentralized virtual machine called Ethereum Virtual Machine (EVM) that can run scripts using an international network of public nodes.
Ethereum is the biggest decentralized software app. It helps you to build smart contracts and decentralized applications without any downtime or any third-party interference. Ethereum allows the developer to create and publish next-generation distributed applications.
In this Ethereum tutorial for beginners, you will learn Ethereum basics like:
Centralized systems are one of the most widespread models for software applications. This system directly controls the operation of the individual units and the flow of information from a single center. In this kind of system, individuals are depended on the central power to send & receive information.
However, there are issues with the centralized system are:
Decentralized applications never reply on a centralized backend, but they interact directly with a blockchain. Refer this tutorial to learn more about BlockChain
The term DApp is a combination of two words- decentralized applications. In simple words, it is an application, tools, or programs that work on the decentralized Ethereum Blockchain.
A Smart Contract is a computer program that executes automatically. It is a transaction protocol that allows blockchain users to exchange money and property. It also helps users to perform actions like voting without any central authority. It is a virtual third-party software agent that can automatically execute and enforce terms and actions according to the legal agreement.

Duration | 103 Days | Minutes |
Remittance | Manual | Automatic |
Escrow | Necessary | Necessary |
Cost | Expensive | Fraction of the cost |
Presence | Physical presence | Virtual presence |
Lawyers | Lawyers are important | Lawyers may not be necessary |
Ether is a value token of the Ethereum blockchain. It is listed as "ETH" on cryptocurrency exchanges. It helps you to pay transaction fees and computational services on the Ethereum network. In the Ethereum network whenever the contract is executed, Ether is paid.
To perform a transaction on the Ethereum network, a user requires to make a payment (to the miner) Ether via an intermediary token called 'Gas.' It is a unit which allows you to measures the computational work required for running a smart contract or other transactions.
In Ethereum, the transactions fee is calculated in Ether, which is given as
Ether = Tx Fees= Gas Limit * Gas Price
