TL;DR · WeSearch summary

The article provides a detailed explanation of Solana's account model by breaking down its four core fields: lamports, owner, data, and executable. Each field is illustrated with real on-chain examples that readers can verify using Solana Explorer. The goal is to give developers a precise understanding of how state is stored and managed on the Solana blockchain.

Key facts

▪Lamports are the smallest unit of SOL and serve both as currency and a storage deposit to keep accounts rent-exempt.
▪Every account on Solana is owned by a program, which has exclusive write access to that account's data field.
▪The data field contains arbitrary bytes whose structure is defined by the owning program, such as token balances or NFT metadata.
▪The executable flag indicates whether an account is a program, with executable accounts storing BPF bytecode in their data field.
