Accounts are not just storage. They're one of the reasons Solana is fast.

Short summary

Solana's account model and parallel processing enable fast transaction execution by storing transactions directly in blocks and processing them in parallel, preventing double-spend through dynamic locking on pre-declared accounts. Unlike EVM chains, Solana avoids mempools and bottlenecks. Accounts store data, programs store code; addresses use public keys for user ownership or program-derived addresses (PDAs) for program ownership.
