Timestamping can easily be *more* vulnerable to malicious miners than finan= cial applications for a number of reasons, including the fact that there's no financial feedback loop of miners destroying the value of the coins they produce - timestamping is a non-financial piggy-back application that doesn= 't directly interact with the Bitcoin economy, beyond a trival number of times= tamp transactions. --=20 https://petertodd.org 'peter'[:-1]@petertodd.org --GLp9dJVi+aaipsRk Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQEcBAEBCAAGBQJZrV7GAAoJECSBQD2l8JH7Zm0H/RWC+eDf2ODQcxtOzNgnU2cm J/q3LIDaRO1Ac2Fr5q4XoDvD718PHSw99M7qvJyVfakjvMyrrkwdhpmFSPto16oS 1M9MeXe9GmqANZ99tNz6hcMV/5te/Gr7UuMXdXJ5GHZ/yiFm0efePynnL9Abcm3I DpxWjr2iSDYrnBxHIUGCvwhaBXWfv0YlQGF5dxYpbi90IjnZJnbPSPdDMnRB0vzR YWtfJ4FNlyRIpOZMz9F1XoxJaLap5qhced/cptnpoiP4EmgEsjyNthEZyWY65Pqi P0zP8h6vL4A6yUMNDeSBQ9dFzypei0La4hYBcad+oohRodDWPBmCR8RgRtW6KcQ= =2nCn -----END PGP SIGNATURE----- --GLp9dJVi+aaipsRk--
