in Hedera, I got the concept of 'digital twin' and the future of identity verification through tokens Because of this, I realized that, in addition to calaxy managing tokens by user, can you consider managing tokens by hedera's token ID? it would be great Using hedera token ID is like the UID number of a facebook account, thanks to the management by uid, managing transactions, advertising numbers, advertising campaigns... of facebook becomes much simpler and easier than other platforms, they do not use uid but simply use user for accounts Using token ID, further resonates the power of identity for accounts, because later most user identities, or even citizen identification numbers... will also come from hedera token id, so it would be great if they added their identity with token id instead of simply with username The username is a characteristic that whoever registers first will own it first. For example, my name is not tony, but I have registered a username with the character tony, so the next registrant will not be able to register with that username, but they can completely replace their username with the iD identification number they own.
