Simple Vote Smart Contract (Part-2): 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 vote smart contract. The Voting smart contract provides a simple and decentralized way to conduct voting on the Ethereum blockchain. It maintains two important mappings: hasVoted and voteCount. The hasVoted mapping keeps track of whether an address has already cast a vote, preventing duplicate voting. The voteCount mapping stores the number of votes received by each candidate, with the candidate's name being the key. The contract exposes a vote function that allows users to cast their vote for a specific candidate by providing the candidate's name as an argument. The function verifies if ...

In software development, DevSecOps refers to the integration of security measures at every stage of the software development lifecycle in order to deliver robust and secure software. In this article, you learned about the Importance of DevSecOps, its implementation, its benefits and etc. DevSecOps Overview According to the DevSecOps definition, it is a strategy of engineering that eliminates silos and allows development, security, and operations teams to collaborate. Its goal is to automate the delivery of secure software and infrastructure to production. In other words, DevSecOps is an extension of DevOps that emphasizes security. As a result, security becomes a shared burden among all team members. Vulnerability assessments are often done at the end of development. Consequently, there is more back-and-forth between teams, more expensive solutions, and resource waste. DevSecOps can be integrated into your development pipeline to build a cyclical process for testing a...

Several blockchains in the NFT area are gaining popularity, and NFT aficionados and crypto artists have been looking for alternatives to the Ethereum network due to its high transaction costs and environmental impact. It is essential to consider several factors to decide which blockchain to mint on. These include network scale, creator expenses, consumer purchasing patterns, security, and community involvement. To bring some clarity to the fast-paced world of web3 technology, we've put together a complete overview of blockchains for NFTs. NFT blockchains vs. NFT marketplaces In the absence of blockchains, NFTs lose their inherent property as immutable, verifiable, unique identifiers. Consequently, the NFT is useful for determining and validating ownership across various sectors, including art, intellectual property, real estate, and collectibles. In a public-accessible NFT marketplace, users can mint, buy, and sell NFTs. The majority of NFT blockchains offer their ...

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, ...
