#27 Simple Lottery Smart Contract

Welcome to this brand new course about blockchain. In this course and the next ones we will make you familiar with all you need to know about blockchain and also will 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 lottery smart contract. The smart contract presented in this video is a simple lottery contract built on the Ethereum blockchain. It serves as a decentralized platform for conducting lotteries with transparent and auditable results. The contract allows participants to enter the lottery by sending Ether to the contract's enter function. The addresses of the participants are stored in the players array. The contract includes a pickWinner function that can only be called by the manager, who is the address that deployed the contract. The pickWinner function randomly selects a winner from the list of players and assigns the winner's address to the winnerAddress variable. Once a winner is determined, the players array is reset to prepare for the next round. The getPlayers function enables anyone to view the list of participants. This smart contract is useful in scenarios where a fair and transparent lottery system is required, such as fundraising events, raffles, or other games of chance conducted on the blockchain.

A smart contract is a program that runs when certain conditions are met on a blockchain. An automated agreement executes so that all parties can see its outcome immediately without involving an intermediary. In addition to automating workflows, smart contracts can also trigger the next action when conditions are met. This blog discusses how smart contracts are changing the world around us and the benefits they will bring to the market in the future. What is a Smart Contract? The terms of a smart contract can be established in the same way as those of any other contract. However, unlike traditional contracts, a smart contract is executed as code running on a blockchain, for example, Ethereum. From loans and insurance to logistics and gaming, it offer sophisticated peer-to-peer functionality backed by blockchain security, reliability, and accessibility. Types of Smart Contracts Here are some types of self-executing smart contracts. Smart Legal Contra

Vyper vs. Solidity: Smart Contract Languages for Ethereum

Image
Smart contracts are the most critical aspects of the blockchain ecosystem. Smart contracts offer the ability to create self-executing code based on specific conditions. However, developers are constantly concerned with the Vyper vs. Solidity comparison and the similarities between their functions. In terms of creating smart contracts, which is a better choice? The older solution, Solidity, has been around for a long time. On the other hand, Vyper is relatively new but offers better performance for smart contract development. To find out which one is the best option, we will discuss the important differences between Solidity and Vyper. What Is Smart Contracts? Blockchain technology is characterized by smart contracts, which were introduced on Ethereum for the first time. Today, Ethereum supports the use of smart contracts in the largest ecosystem. It is important to note that without smart contracts, you wouldn't have popular apps like Uniswap or Aave. Essentially, smart contr
