Ethereum is open-source and still growing. People come here out of genuine interest. This isn't traditional tech. It's enormous — no course can cover it fully. Everyone works in their own niche. Explore from whatever resources you find.
Ethereum has two sides:
- The core protocol — the blockchain itself. Consensus, blocks, validators, finality.
- The application layer — everything built on top. Smart contracts, development, security.
The blogs here cover some of the most important topics in depth. Not a course from zero, but vital concepts explained properly.
- Foundry from Zero — the most important tool on the application side. Writing contracts, testing, scripting, sending real transactions on-chain.
- WTF is ABI Encode/Decode — how contracts talk to each other and to you. Function selectors, calldata, encoding, the full story.
- The Proxy Story — five ways Ethereum developers have solved contract upgradeability. Transparent, UUPS, clones, beacons, diamonds.
- Call, Send, Transfer — from the 2016 DAO hack to today. The full timeline of how Solidity handles ETH transfers and why it changed.
- Account Abstraction — EOAs are broken. Here's how Ethereum is fixing them. ERC-4337, EIP-3074, EIP-7702, the full evolution.
- ERC-7540 — async vaults, how they work, and where they break.
