Only BPID allows users to create their own controllable anonymous identity
Everyone has done this:
Perhaps you lost your keys, your pet, a phone, or perhaps, your luggage. You don’t want other people knowing the keys they found is for your apartment and where you live so you don’t put your name and address on your key ring.
Or perhaps there’s a medical condition or emergency. You want to be contacted immediately even if you are on vacation but you don’t want to disclose what the medical condition is, medications you are taking or your travel schedule.
In any case you want people to be able to reach you, but you simply don’t want your identity published or stolen.
BPID’s answer is simple: the “Verifiable Anonymous Identity“.
