Question 21

Solana programs vs Eth programs with regard to state

Answer 21

Remember earlier I said Solana programs are stateless. They don’t hold data permanently. This is very different from the world of Ethereum smart contracts — which hold state right on the contract.
But, Solana programs can interact w/ “accounts”.
Again, accounts are basically files that programs can read and write to. The word “accounts” is confusing and super shitty. For example, when you create a wallet on Solana — you create an “account”. But, your program can also make an “account” that it can write data to. Programs themselves are considered “accounts”.
