How Solana Works https://solanahowitworks.xyz/
Rent on Solana ⇒ Rent is a mechanism on the Solana blockchain that ensures efficient usage of the blockchain’s resources. It requires accounts to maintain a minimum balance proportional to the amount of data they store on the network. Accounts that fail to maintain this minimum balance will be removed from the ledger to free up storage. And Rent is Refundable.^Rent-Explanation There are two ways to store data on BlockchainEither you store some amount from which rent will be deducted for every few minutes or store an minimum amount such that you no need to pay rent at all. For example Banks required minimum balance to keep your account alive or pay some money every month to keep your account alive

  • To know how much rent needed to be store the data use this command in Solana CLI
