The FIO Chain inherits EOSIO resource management, but makes a number of modifications to it to remove the user complexity, while supporting its fee model.

RAM limits

Every new account will have initial RAM allocated to 25600 bytes (25K). Every time an account pays a fee or covers a transaction from a bundle, that account’s RAM will be permanently increased by the number associated with the executed action. In case of multi-action transactions, each action will increment the RAM independently.

Example

Account A registers a FIO Crypto Handle for themselves
Account A RAM is increased by 2,560 bytes
Account A transfers funds to a key not associated with an account
Account A RAM is increased by 2,560 bytes
Account B is created with initial limit of 25KB of RAM

Scheduled BP RAM override

When a BP is added to the BP schedule to produce blocks, their RAM limit will be changed to unlimited. When a BP is removed from BP schedule, their RAM will be changed to existing RAM usage of their account + 25K.

Transaction size limit

Every transaction is limited to max size of 8098 bytes. BPs in schedule are exempt from the transaction limit for propose actions.

CPU limit

All accounts are created with unlimited CPU, as only authorized contracts with pre-approved CPU usage can run on the FIO Chain.

NET limit

All accounts are created with unlimited NET, as there is a transaction size limit.
