Hello friends, hope you are doing fine and doing great. In the previous tutorial for introducing Smart Contracts, I told you about Solidity. Solidity is a high-level programming language for writing smart contracts. It is the most popular programming language for Ethereum. So, in this article, I will explain the basic components of solidity. Let’s get started by revising the key points of solidity.
Solidity Programming
Solidity programming language is made for writing code for the Ethereum platform. These codes (smart contracts) help in executing different functions in Ethereum virtual machine (EVM).
It is easy to learn the language. If you are familiar with C and JavaScript, you can easily learn solidity.
The code written in solidity is con ...
Hello guys, hope you are doing good and enjoying your lives. Today, I am going to introduce you to the blocks of a blockchain. I gave you an understanding of blockchain, its characteristics, and some idea about accounts and wallets in my previous tutorials, and today my article is about the structure of a block in the blockchain.
I will first define the block before going into the details about its structure. So let’s start without any further delay.
Block in Blockchain
A block is actually the building block or the key element of a blockchain.
The definition of a blockchain is based on its blocks. As I defined in my previous posts, a blockchain is a chain of multiple blocks.
Blocks contain transac ...
Hello friends, I hope you are happy, healthy and content. We have been discussing embedded systems lately and this discussion would be incomplete without an in-depth discussion on Real time embedded systems. You might have observed their utility and their absolute need in our constantly changing external and internal environment, the ease of managing the room temperature with a single tap, generating several results with a single click and streaming videos and playing games anytime and anywhere are the blessings of real time embedded systems.
Definition of Real Time Embedded Systems
Real time embedded systems can be defined as;
"The embedded systems which respond to real time situation with the help o ...

Hello friends, Hope you are doing fine and having a good time in your life. The topic that I am going to discuss today is a very interesting and important one in the context of blockchain. I will discuss smart contracts in this article and I am sure you will learn the concept by the end of this tutorial. I have mentioned smart contracts in my previous articles and defined them before.
Before discussing smart contracts, let’s first revise what a contract is, and then we will talk about smart contracts.
Contract
When two persons or two parties want to carry out a deal or a transaction such as buying property, they need some proof for future reference.
So, a contract between two or more individuals is a legal document that serves as proof for t ...
Hello friends, hope you are doing fine and enjoying your life. In today’s article, I am going to discuss decentralized applications that are abbreviated as dApps. With the invention of blockchain technology and afterward Ethereum, the idea of decentralized applications has gained a lot of attention. So let’s get into the details and learn what a dApp is.
Decentralized Applications (dApps)
An application built on a decentralized platform such as Ethereum is called a Decentralized Application(dApp).
A dApp generally consists of a backend and a frontend.
The backend of a dApp is a smart contract mostly written in solidity language.
The front end of a decentralized application is the user in ...
Hello friends, hope you are doing good and enjoying your life. Today, I am going to introduce you to the Ethereum wallets. I have given you an introduction to blockchain, its characteristics, and an introduction to accounts in my previous tutorials, so let’s get started with today’s tutorial on Ethereum wallets.
What is Ethereum Wallet???
In this section, I will introduce you to the Ethereum wallet and then we will move into its further details.
A blockchain wallet is just like a real-life wallet but in software form. It is the digital form of a wallet.
A wallet is application software that acts as a user interface to the Ethereum network.
The wallet is a system to manage and store the keys.
This digital wallet allows transferring crypto ...
Hello friends, hope you are doing good and enjoying your life. Today, I am going to introduce you to Ethereum accounts. I have given you an introduction to blockchain in my previous tutorials, so let’s get started on the essentials of this technology. I am going to start with accounts.
Ethereum Accounts
An account is an important component of the Ethereum system.
It is the main building block and has a balance in ether (ETH) (Ethereum currency).
An account is capable of sending transactions on the Ethereum network.
The interactions between different accounts create transactions that are stored in the distributed database.
Each transaction involves the sender account, receiver account and contract account.
An account can be controlled b ...
Hello Friends, Hope you are doing fine and having fun in your lives. In my previous tutorials on blockchain and Ethereum, I have talked about mining a few times. So, in today’s article, I am going to discuss the concept of mining with you. This is an important part of learning the working of blockchain to see how the decentralization of blockchain happens. Let’s start today’s article by defining mining.
Blockchain Mining
As blockchain is a peer-to-peer network. Mining is also a peer-to-peer process.
Blockchain (or Ethereum) mining is used to verify transactions on the network.
In this process, miners (the person or node who performs mining) add transaction records to the decentralized distributed ...
Hello friends, Hope you are doing good. In my last tutorial, I gave you an introduction to blockchain technology and this article is the second one of this series. Today I am going to talk about Ethereum. In simple words, Ethereum is an open-source platform of blockchain technology. But unlike the bitcoin blockchain, it offers more functionality. The blockchain in bitcoin tracks bitcoins only. It tracks the ownership and transfer of bitcoins. While Ethereum is not only a payment network for cryptocurrency but also termed as the world computer due to its wide functionality. First, let’s go through the key introductory points of Ethereum, and then we will dive into the details:
What is Ethereum Blockchain?
Ethereum blockchain is an open-source g ...
