HOWEVER, the more i think about that type of system, the more i like hashcash better. ...atom _________________________________________ PGP key - http://atom.smasher.org/pgp.txt 762A 3B98 A3C3 96C9 C6B7 582A B88D 52E4 D9F5 7808 ------------------------------------------------- "Unthinking respect for authority is the greatest enemy of truth." -- Albert Einstein -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.3.6 (FreeBSD) Comment: What is this gibberish?
