There are three basic things that related to resources that need to be considered when using Vexanium blokchain which is RAM, CPU, and NET.
RAM is used to store data on blockchain. Users will need RAM to create a new Vexanium account, add information to their account such as token ownership in other Vexanium blockchain and DApps will use RAM to store information on the state of their application so the information will quickly available when needed. In both cases, RAM is used to store data records on Vexanium blockchain.
In the case of creating a new account on Vexanium, it does require some portion of the RAM that has to be purchased to store the actual account details (such as account name and creation date). For the moment, a minimum of 4K RAM is required to create an account.
One other thing to keep in mind when we talking about RAM is when a VEX account receives a new VEX token for the first time, new records will be added to the blockchain. The storage space for the note needs to be purchased. In the future after your account has any additional RAM transaction from an account with this type of token, it will not cost you anything. Even if you zero the account completely there will be still records on the blockchain stating you hold zero token from the given type.
CPU refers to the data processing power that you can use on Vexanium network and hence, NET refers to the network bandwith that you are permitted to use. Both resources are measured as your average usage in the past 3 days. The more Vexanium you are staking, the more resources you are allowed to use.
