#Solana accounts explained in 5 tweets π
1/ There are 2 kinds of accounts in Solana.
Data accounts store data. Program accounts store executable programs.
Each account has an address (usually a public key) and an owner (address of a program account). There are a few more fields every account stores, see π

2/ There are a few important ownership rules:
- Only a data account's owner can modify its data and subtract lamports.
- Anyone is allowed to give lamports to a data account.
- The owner of an account may assign a new owner if the account's data is zeroed out.

3/ If you're coming from Ethereum, there's one major differenceβprogram accounts do not store state!
E.g., if you have a counter program that lets you increment a counter, you must create two accounts: one account to store the program's code, and one to store the counter.

4/ To prevent an account from being deleted, you must pay rent.
Why? B/c account data is stored by nodes in the Solana network. And that costs $!
Rent is regularly deducted from an account's balance. But, if an account has enough lamports, it is exempt from rent.

5/ Let's recap:
- There are 2 types of accounts, data accounts and program accounts.
- Each account has an address (usually a public key) and an owner (a program account).
- Program accounts don't store state (unlike Ethereum).
- Accounts must pay rent to stay alive.
