🔍 Day 46 of #100DaysOfBlockchain: Fuzz Testing Unveils Hidden Vulnerabilities

Today, I dove deep into fuzz testing, invariants, and handler contracts in my smart contract security course. Focusing on stateful and stateless fuzz testing was both challenging and fascinating.

🛠 What I Learned: I discovered a sneaky issue—a malicious ERC20 token that steals 10% of transfers after the 10th transaction. It was a real eye-opener, showing just how crucial fuzz testing is for catching vulnerabilities that regular tests might miss.

🚀 Why It Matters: While I’m not aiming to become a security researcher, this course is helping me write more secure smart contracts. Today’s lesson highlighted the importance of making sure contracts can handle the unexpected.

🌱 Takeaways: Fuzz testing isn’t just about finding bugs; it’s about building resilient systems. Each challenge I tackle moves me closer to becoming a top-tier smart contract developer.

Great job on completing your first smart contract audit! Ensuring security and reliability in code is crucial in the blockchain space. Looking forward to seeing your progress as you delve deeper into smart contract security. Keep up the good work! 🚀🔐

🚀 Day 33 of 100DaysOfBlockchain: Exploring zkSync and Zero-Knowledge Proofs 🏅

🔍 Introduction to zkSync Today, I dived into zkSync, which utilizes zero-knowledge proofs, an innovative solution to scalability in the Ethereum ecosystem. Zero-knowledge proofs are a way for one party to prove to another that a statement is true without revealing any specific information about the statement itself.

⚙️ Zero-Knowledge Proofs in Simple Terms Zero-knowledge proofs allow someone to confirm they know a secret without revealing the secret.

📜 Integrating zkSync into Projects I spent time updating much of my older projects with zkSync's zero-knowledge proof technology, significantly enhancing scalability. 

🚀 Bridging and Deploying on Testnets Today involved refreshing my knowledge on integrating zkSync into my projects, focusing on lessons about bridging Sepolia testnet to zkSync testnet ether and deploying to testnets at a fraction of the cost.

Impressive progress on your blockchain journey! zkSync and zero-knowledge proofs are indeed game-changers for scalability. Your dedication to integrating this technology into your projects shows a commitment to staying at the forefront of innovation. Keep up the great work! 🌟👏
