When I first started learning Solana, transactions felt like magic. You click "Send", wait a few seconds, and somehow value moves across a decentralised network. But after spending time building and debugging transactions myself, I realised that every Solana transaction has a very clear structure underneath it. And honestly, understanding that structure made blockchain feel far less mysterious. A transaction is more than “sending crypto” Coming from Web2, I initially compared a Solana transaction to an API request. You send data somewhere, something processes it, and the system changes state. That analogy helps at first, but it breaks pretty quickly. A Solana transaction is closer to a signed package of instructions that the network verifies before allowing any state change to happen. It’s atomic too, meaning either everything succeeds or nothing does, similar to a database transaction.…
