In EOS, there are three types of resources: RAM, CPU, and NET. Users can mortgage EOS in exchange for the right to use resources.
RAM is memory, used to record account information, including account balances, public keys, pledges, voting, smart contracts, and more. A capacity of 3KB-8KB is usually required to store personal EOS account information. RAM can be bought and sold at any time, each charge a 0.5% fee, and the price also changes with the scarcity of RAM.
CPU/NET is a resource of the pledge type. When the EOS account is transferred, voted, etc., it will consume the computing power and bandwidth of the main network. In this case, some EOS needs to be pledged in exchange for CPU/NET, and the daily computing power and bandwidth will be reset after 24 hours. The pledge of EOS can be redeemed at any time, but there will be a 72-hour freeze period.
