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.
