Description

Satoshi Proof is your personal notaryleveraging the power of the Bitcoin network to prove existence oftext or images at a certain time.

Examples:
- Prove that a certain damage existed before a given time ( rentalcars, flats, .. ) by proving the existence of an image of thisdamage at a certain time
- Prove that a certain idea ( text ) was existing before a giventime ( e.g. for prior art arguments against patents )

First you select a picture or enter text - then the system checksif the existence is already proven and prints out the time if so.If not you get the option to prove the existence now bytransferring one Satoshi to a calculated address.
The money is going nowhere ( or to a random stranger ) - but it isso little that this should not matter. Note: it can take some timeuntil the existence is signed by the network - especially withthese small amounts ( you can increase the amount if you wantfaster signing ).
