đ Original message:*One of my biggest fears about using any wallet is the "whoops, cosmic ray
flipped a bit while producing receiving address; SFYL!" possibility. For
high value cold storage, I always generate my addresses on two independent
machines using two different pieces of software. Am I nuts for doing that?*
A randomly flipped bit would be extremely unlikely to yield a valid
address, however, I still think it you are wise to use independent routes
to confirm that your addresses match the keys. I do the same when I
generating my cold storage key pairs. I think malicious address
substitution is an under appreciated attack vector.
Regarding this thread in general, would it make sense for this proposal to
include standards for multi-sig wallet interoperability? A whole spectrum
of attacks would be made less likely - and easy for typical users to guard
against - by using wallets on separate devices AND where the wallet
software was written and provided by different parties.
