Hello,
I started a great discussion over here:
https://bitcointalksearch.org/topic/lets-embrace-btc-trusted-timestamping-139443 about timestamping files with BTC.
Please read my posts and share your thoughts:
A] You share my vision of BTC Timestamping, fully embrace the point about 'Verifiability' I raised on the second page, and, in fact, will push for its inclusion in Armory and all clients.
B] You think its a great idea but aren't sure its worth the effort or will catch on (you're wrong!).
C] You have problems with the idea (please share them).
I have code to do this in Python, but its so simple that perhaps eipi will just want to do this himself in ~15 minutes. Armory's multiple wallets feature is already a major pro in the ultra-easy implementation of this, as it is essentially ImportPrivateKey(Hash(file)), but you dont want anything to happen to your existing wallet.
This is a very simple feature but without standardization and ease-of-use (read: Windows GUI) there will be insufficient Verifiability...I am reaching out to the Electrum community as well!
What do you think?
