Blockchain consensus, Ethereum's account model, Solidity smart contract basics, wallet integration with ethers.js, and a frank assessment of where Web3 is technically mature versus where the trade-offs make it the wrong tool. No speculation, no token promotion.
This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on web3 you can find — even without producing a single minute of custom video.
This course is built by engineers who ship web3 systems in production. It reflects how these tools actually behave at scale.
Every day includes working code examples you can copy, run, and modify. Understanding comes through doing.
Instead of re-explaining existing documentation, this course links to the definitive open-source implementations and the best reference material on web3 available.
Each day is designed for about an hour of focused reading plus hands-on work. Do the whole course over a week of lunch breaks. No live classes, no quizzes.
Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.
Distributed ledgers, cryptographic hashing, Merkle trees, consensus mechanisms (PoW vs PoS), finality, Ethereum's account model vs Bitcoin's UTXO model, and the properties blockchain provides vs what it doesn't.
Solidity syntax, state variables, functions, events, the EVM execution model, gas costs and why they matter for contract design, basic token contract (ERC-20 standard), and the Remix IDE for rapid contract development.
Hardhat for local blockchain development, writing tests with ethers.js, deploying to testnets (Sepolia), contract verification on Etherscan, and the security patterns that prevent reentrancy and integer overflow vulnerabilities.
MetaMask integration, ethers.js Provider and Signer, reading blockchain state, sending transactions from the browser, handling transaction states (pending, confirmed, failed), and the UX patterns for Web3 applications.
IPFS for decentralized file storage, ERC-721 NFT standard, building a simple NFT mint, and an honest assessment of Web3's current limitations — throughput, UX complexity, regulatory uncertainty — and where blockchain adds genuine value vs where it's the wrong tool.
Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.
How blockchains work — consensus, hashing, Merkle trees, and the properties that distributed ledgers provide and don't provide.
Writing, testing, and deploying Solidity smart contracts on Ethereum — syntax, EVM, and the security pitfalls to avoid.
Local Ethereum development with Hardhat — contract compilation, testing, deployment to testnets, and Etherscan verification.
Connecting a web frontend to Ethereum with ethers.js — MetaMask integration, reading state, and sending transactions.
Storing NFT metadata on IPFS, the ERC-721 standard, and the minting flow for a simple NFT contract.
The best way to deepen understanding is to read the canonical open-source implementations. Clone them, trace the code, understand how the concepts in this course get applied in production.
The most-used Ethereum development environment. The /packages/hardhat-core directory shows how the local blockchain node, test runner, and deployment scripts work.
The standard JavaScript library for Ethereum interaction. Provider, Signer, and Contract abstractions — reading the source makes Web3 frontend patterns clear.
Audited Solidity contract templates — ERC-20, ERC-721, access control, and upgradeability patterns. The foundation for nearly every production Ethereum contract.
The official Ethereum documentation site source. The /src/content/developers directory has the canonical developer guides for every topic in this course.
This course explains what blockchain actually does and doesn't do, so you can evaluate whether it fits a technical problem — not whether the token price is going up.
When your company asks whether blockchain solves a problem, you need enough technical depth to give an honest answer. This course covers the real trade-offs.
Solidity is a real, deployable programming language. This course covers enough to write, test, and deploy simple contracts — without the speculation narrative.
