Hi Heiko,

Very interesting. Actually I'm familiar with OpenTimestamps and RFC 3161
timestamping. I've also used raw Bitcoin transactions to timestamp my
key's fingerprint [0] and recently did a small PoC of using Google's
Roughtime protocol to timestamp arbitrary data.

It's definitely nice to see timestamping being considered in scope of
OpenPGP. I'll keep an eye on T4108.

Thanks for the pointers!

Kind regards,
Wiktor
