Week 2 of #100DaysOfSolana — Breaking down what I built and learned, day by day. 🔥

This week was packed. Here's exactly what went down:

📅 Day 8 — Reading Solana Data

Learned how to fetch and read on-chain data using a public address. The blockchain is fully transparent — you just need the right tools to query it. First time pulling live data felt like unlocking a superpower. 📖⚡

📅 Day 9 — Transactions in Solana

Went deep into how Solana transactions are structured, signed, and processed. Understanding the anatomy of a transaction — instructions, signers, recent blockhash — changed how I see every on-chain interaction. ✍️🔗

📅 Day 10 — Building a Solana Dashboard

Put Days 8 & 9 together and built a full dashboard that reads account data and transaction history from any public address. First real project of the challenge — turning raw blockchain data into something visual and usable. 📊🛠️

📅 Day 11 — Solana Accounts vs Traditional Databases

This one flipped my thinking. Solana accounts aren't database rows — they're more like files that store state, owned by programs. The shift from a Web2 database mindset to an on-chain storage model is real and essential. 🧠🗃️

📅 Day 12 — Devnet vs Mainnet

Understood the critical difference between Devnet and Mainnet — same code, completely different consequences. Knowing when and why to use each environment is foundational before you ship anything serious. 🚨🌐
5 days. 5 solid concepts. Each one building on the last.
The foundation is getting stronger — Week 3 is where it gets even more interesting. 🚀
