I see that you can register a .com .net .org account name, but I read that you have to first control the account names com net and org in order to register these new ones. How does one get these 3 letter domain names?
You can buy and sell names on https://eosnameservice.io/
Account names that are 3-11 characters long are considered premium account names. They get auctioned off daily on-chain. You can participate here: https://toolkit.genereos.io/community/bidname
Once you have a premium account name, say
patoshi, you own what we call the namespace. With the
patoshi you will be able to create new accounts in the form
*.patoshi assuming the account name is still less than 13 characters and only uses valid characters (a-z 0-5)
You'd need to reach out to the owner of the
com account name to get access to
patoshi.com. However many namespace owners sell account name in their namespace.
