From: Jan Lindemann <[email protected]> via Cryptography Mailing List
<[email protected]> I came up with a funny idea on how to create an
egalitarian POW mechanism that would let everyone have the same or a very
similar "hashing rate".
To keep it short, it uses the active authentication feature of the NFC chip
contained within passports.
This feature consists in having a private key contained within the chip signing
a challenge to prove that it hasn't been cloned.
So my proposal is to use this signing functionality instead of using the typical
SHA256 or Scrypt hashing algorithms.
Passports have likely a similar singing rate, and people are likely to only have
one passport.
