Everything Is an Account on Solana: A Complete Guide for Web2 Developers
Solana's architecture treats everything as an account, a fundamental concept where all on-chain data and programs are stored in uniformly structured records. Each account contains lamports, an owner, data, and an executable flag, enabling a consistent model for state and program storage. This design separates program logic from state, differing from Ethereum's approach and emphasizing ownership-based access control.
- ▪Every account on Solana has four fields: lamports, owner, data, and executable.
- ▪Only the program that owns an account can modify its data, enforcing access control at the runtime level.
- ▪Programs on Solana are accounts with executable set to true and do not store mutable state.
- ▪Accounts must hold enough lamports to be rent-exempt, determining their eligibility to remain on-chain.
- ▪Wallets, tokens, NFTs, and DEX pools are all implemented as accounts with different data structures.
