Solana Account Model

On Solana, all data is contained in what we call "accounts".

 

Accounts can store up to 10MiB of data, which contain either executable program code or program state.

Account require a rent deposit in lamports that is proportional to the amount of data stored.

Every account has a program owner. Only the program that owns an account can modify its data.

Programs(smart contracts) are stateless accounts that store executable code.

Data accounts are created by programs to store and manage program state.

 

Accounts

Every account on Solana is identifiable by a unique 32byte address, which is generally displayed as a base58 encoded string.

The relationship between the account and its address can be thought of as a key-value pair.

Accounts have a max size of 10MiB and every account on Solana has the same base Account type.

 

 

 

pub struct Account {
	pub lamports: u64,
    #[cfg_attr(feature = "serde", serde(with = "serde_bytes"))]
    pub data: Vec<u8>,
    pub owner: Pubkey,
    pub executable: bool,
    pub rent_epoch: Epoch,
}

 

Every Account on Solana has the following fields:

- data

- executable

- lamports

- owner

- rent_epoch
