A provider does not have to be an interactive third party. One reason I
suggested using X.509 is so secure hardware devices like the TREZOR could
also be instant providers. The hardware would be tamperproof and assert
using a secret key embedded in it that the tx came from a genuine,
unflashed TREZOR. The the server can know the device won't double spend.

In this way you have decentralised anti-double spending. Of course, it's an
old solution. MintChip sort of worked a bit like this.
