Understanding Solana Transaction Structure: Week 3 of #100DaysOfSolana

Short summary

Solana transactions consist of four components: signatures (cryptographic proof), instructions (actions), accounts (data being modified), and recent blockhash (expiration timer). Unlike Web2 APIs, they are cryptographically signed, atomic, and require explicit account permissions. Understanding this structure is critical for developers transitioning from Web2 to building on blockchain.
