Thanks to you @luckyali for the positive evaluation of my post.
Indeed, it seems that KYC processes are a double-edged sword within the blochain environment, however, I consider that within this environment we have all the necessary tools (from which centralized platforms suffer) to be able to carry out these processes without significantly affecting the protection of the identity or other data of the users, except in those cases in which their identification is vital (as in the case of hacks for example)

Can you imagine a "virtual blockchain police" capable of encrypting and decrypting data and protecting all crypto assets? XD

I think I was daydreaming, but it can be a good script for a blockchain movie right? ;)
