Hello friends, Hope you are doing good and having fun. I am here with another article on the blockchain. Previously, we have discussed the blockchain, some of its concepts, and its characteristics, and today I will talk about transactions. We would also explore the concept of gas in this tutorial. So let’s start by defining a transaction.
What is Ethereum Transaction?
A transaction is a message signed by an account owner that is added to a block and recorded in the blockchain.
A transaction is initiated by an externally owned account and then it gets transmitted to the Ethereum network.
It can be originated only by an externally owned account (an account owned by a human) and not by a contract account.
Through transactions, one can inter ...
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 ...
