Highlights
The video introduces a list of engaging and resume-building projects for Web3 and blockchain developers. The speaker shares personal experiences and highlights that many of these projects are covered in their 'Blockchain Expert' course, emphasizing the course's comprehensive approach to learning, including fully guided projects and upcoming Chainlink integration.
The first project recommended for beginners is a blockchain bank account. This project is crucial for understanding how to securely send and receive Ethereum to a smart contract and manage user balances. Extensions could include implementing interest rates, monthly fees, or deposit fees. The speaker stresses the importance of writing automated tests for smart contracts and building a front-end for user interaction, mimicking a traditional banking application.
Following the bank account project, the next recommendation is a decentralized exchange (DEX). This project focuses on interacting with ERC-20 tokens, obtaining user approvals for token transfers, and receiving tokens within a contract. Developers can start with a basic version allowing users to trade custom ERC-20 tokens at a specified price, or advance to creating a liquidity pool with LP tokens that accrue interest.
An NFT auction project is suggested to learn about ERC-721 tokens and the InterPlanetary File System (IPFS). This involves creating an NFT, storing its metadata and associated images on IPFS in a decentralized manner, and then building an auction contract. The auction contract should handle accepting NFTs, managing timed auctions, processing bids, determining winners, and transferring NFTs. A front-end would display ongoing auctions, bidding history, and NFT statistics.
Leveraging IPFS knowledge, the next project is a decentralized voting protocol. This involves creating an organizational structure where members (e.g., paid or whitelisted users) can create and vote on polls. Poll data, including descriptions and options, would be stored on IPFS. The front-end would display the poll, allow eligible users to vote, and track expiry dates, essentially creating a democratic system on the blockchain.
For more advanced developers, the video suggests larger projects involving Chainlink and Layer 2 solutions. Chainlink allows bringing off-chain data (e.g., sports results) onto the blockchain, enabling applications like decentralized gambling platforms. Additionally, developing games on the blockchain is explored, but with a focus on Layer 2 solutions like Roll-ups to overcome the blockchain's inherent slowness. Roll-ups bundle transactions, allowing for faster, more synchronous gaming experiences than traditional Layer 1 implementations.
The video concludes by reiterating the value of these projects and strongly recommending the 'Blockchain Expert' course for anyone serious about becoming a proficient Web3 and blockchain developer. The course promises extensive content, practical projects, and the confidence to create smart contracts.
