Sophisticated Sybil attacks

Well, we have talked of these rules again during last Freedom Money Meeting (5th), and we concluded 2 things:

  • people should be limited in the number of concurrent valid signatures they can issue
  • this rule, mixed with the distance rule, implies a maximum size of the community

And we imagined that a community:

  • requiring individuals to gather 8 signatures to be a member
  • requiring a maximum distance of 5 between its members
  • limiting members to issue 16 concurrent signatures

would lead us to a maximum size of ~1 million people community. Possibly a bit more, but mathematical max is ~2 million.

For comparison, Google is composed of 50.000 people.
