I don't know how Calaxy will handle usernames with long characters in the future, when there are billions of users? Instead of just using usernames, assign more serial numbers to each account in the form of ID serial numbers, just like the serial numbers of Facebook social network, for users they are numbered by UID, and for fanpage groups they are in ID order, they are even classified by industry, because in the future, advertising strategies on the platform will be very large, and not assigning users by serial numbers will certainly encounter many obstacles in management In addition to the idea of assigning serial numbers as above, it is also possible to use the wallet code as an equivalent account authentication tool, instead of just displaying the username as it is now, users can optionally display it as their wallet code id will not encounter annoying duplication by people with bad intentions, creating usernames with names similar to KOLs or famous people for bad purposes
