I hate biometrics. Biometrics is the ultimate privacy invasion, and I am a hardcore anonymity advocate. An alternative proof of individuality that does not require biometrics is the proof of individuality that can be implemented if you apply my proposal
. Unfortunately there is not a single cryptocurrency community on earth that has ever applied cryptoparties as a mean of proof of individuality. Many physical cryptocurrency meetings take place all over the world, but no one has ever put a ballotbox, let the attendees put printed wallets/ public keys inside it, in order for the attendees to be anonymized .
