Payment Smart Contract: Welcome to this brand new course about blockchain. In this course, and in the upcoming ones, we will make you familiar with everything you need to know about blockchain. We will also teach you some of the latest blockchain coding skills so that you can enter the fascinating world of decentralized applications. In this video, we will learn about simple payment smart contract. The Payment Contract is a smart contract designed to facilitate payments between two parties on the Ethereum blockchain. It includes variables to store the addresses of the payer and payee, as well as the payment amount. Upon deployment, the constructor initializes the payer as the address of the deploying account and the payee and payment amount are provided as arguments. The contract provides a function called makePayment() which can be called by the payer to initiate the payment. It ensures that only the payer can make the payment and checks if the contract has sufficient balance to

Cryptographic assets on a blockchain known as nonfungible tokens (NFTs) are digital objects that are intangible and unique, such as art, photos, in-game collectibles, or tweets, which other assets cannot replace due to their exceptional properties. As a result, it is neither expensive, complex, nor technical to create an NFT. Anyone can create an NFT without writing codes and with the right guide. Anyone who wishes to sell and share their digital creations, such as content, art, music, and photography, can do so. Here's a guide on how to create a nonfungible token successfully. How Do NFTs Work? An NFT involves the creation of digital tokens through a technique called cryptography. This token creation process is commonly known as minting. To mint an NFT, you usually have to use cryptocurrencies to create smart contracts. NFTs and their ownership are managed by smart contracts, which are pieces of software code that enable blockchain to store information securely a

Simple Storage Smart Contract: Welcome to this brand new course about blockchain. In this course, and in the upcoming ones, we will make you familiar with everything you need to know about blockchain. We will also teach you some of the latest blockchain coding skills so that you can enter the fascinating world of decentralized applications. In this video, we will learn about simple storage smart contract. The Solidity Simple Storage smart contract is a basic example of a smart contract that demonstrates how to store and retrieve data on the Ethereum blockchain. It utilizes a single variable called data to hold an integer value, which can be updated and retrieved by the contract's functions. The contract includes a setter function setData that allows users to modify the value of data, and a getter function getData to retrieve the current value. By deploying and interacting with this contract, users can gain a better understanding of the fundamental concepts of state variables,

Using individual Virtual Network Functions (VNFs), a fully virtualized environment can be constructed by connecting or combining them as building blocks. On top of hardware networking infrastructure, VNFs run on virtual machines (VMs). They can run on multiple hardware boxes using all of their resources. In this article, we will discuss the architecture and components of VNFs, their advantages and limitations, and how they differ from NFV. What Are Virtual Network Functions (VNFs)? To achieve agility, flexibility, and dynamic scaling in network infrastructure, Network functions virtualization (NFV) and Software-defined networking (SDN) are being used in technology transformation. Software-defined networking (SDN) allows network administrators and operators to take complete control of their networks, and NFV replaces the network equipment with a virtualized infrastructure. On this virtual infrastructure, Virtual Network Functions (VNFs) will run and host. Virtual Network

Getting Started with Solidity: Welcome to this brand new course about blockchain. In this course, and in the upcoming ones, we will make you familiar with everything you need to know about blockchain. We will also teach you some of the latest blockchain coding skills so that you can enter the fascinating world of decentralized applications. In this video, we will get started with Solidity on Remix IDE. This IDE is browser-based and enables you to easily write, debug, compile, and deploy your smart contracts on different Testnets, Mainnets, and local networks.

Fungible tokens are interchangeable. one unit is the same as another. Whereas non-fungible tokens are unique. No two units are alike. Token fungibility is determined by its degree of divisibility. For example, a Bitcoin can be divided into 100 million smaller units known as satoshis, which are interchangeable. As a result, each Bitcoin is fungible. However, Ethereum's native token, Ether, is not fungible. This is because it is not divisible. Rather than being divided into smaller units, one Ether must be exchanged for another Ether. What are Tokens? Crypto tokens, or tokens representing assets, are a type of cryptocurrency. Blockchain technology and Ethereum are here to stay, regardless of whether you believe it. Crypto tokens represent an asset and can be anything of value. NFTs are the next significant evolution in this ever-changing digital world, as cryptocurrencies are proving their legitimacy and value. The pandemic accelerated digital technological changes ov
