1/5 On-chain DAO voting is broken. It secretly taxes every token holder for security. I developed a new model to fix this. Introducing Reactive Governance: A new design for secure, scalable, AND gas-efficient on-chain voting. 🧵 Full research & solution. https://t.co/BCPmUhaqiy

TL;DR: The current standard for secure on-chain voting(ERC20Votes) imposes a hidden "gas tax" on every single token transfer, making tokens less efficient for everyone. I've developed a new open-so...

Week-1 Day-4: EVM Portfolio Tracker (Dissertation) Today was mostly about improving the data pipeline and project structure. 1. While working on https://t.co/53lCXSIWZ5, I realized returning the full dataset at once isn’t ideal when we’re processing data in batches. So instead

Week 1 — Day 3 of building EVM Portfolio Tracker (Dissertation) Today I built a proper token layer so I don’t have to keep re-solving the same problems in every script. I added a token_registry.py module that works hand-in-hand with https://t.co/53lCXSIWZ5: •

Week 1 dissertation progress: EVM Portfolio Tracker. Day-2 Built https://t.co/53lCXSIWZ5, a small token-discovery + caching layer on top of @coingecko . What it does: • Fetches the valid tokens listed on CoinGecko • Stores a local cache so I’m not hitting the API constantly

My Cyfrin's progress is stuck rn, will start to work on it again as soon as I get the Dissertation to a MVP stage. Rn I'm fully invested in this, I have been working on the idea for a while now, finally landed on one.

Dissertation topic locked: EVM Portfolio Tracker. Week 1 goal: get the data layer working (CoinGecko + Etherscan) before I even think about UI. Today’s build: • Started with Etherscan (Ethereum only for now) • Pulled wallet transaction history • Normalized the response:

Reentrancy Guards in Solidity: Basics + Why They Matter + OpenZeppelin's Latest Upgrades 🔥 Reentrancy = deadly vuln where attacker re-calls your function mid-execution → drains funds (e.g., DAO hack ~$60M lost). Guards lock the function during external calls to prevent this.
