# 3.30 Account

Rather than utilize a public-key derived address to denote each account, `AMC` adopts an account model based on an account name. One account can be bound from one or multiple public keys and the key requires its owner to register/activate it before any transaction can be made within the account. Each account name is composed of 12 alphanumeric characters (\[`1-5`,`a-z`,`.`]) and can be extended to support 24 such characters (\[`1-9`,`a-z`,`.`,`#`,`@`]). To participate in all kinds of transactions, account owners must stake a certain amount of `$AMAX` tokens to reserve a certain amount of system RAM, CPU, network and other resources.
