OTScam

Créer une preuve OpenTimestamps chaque fois que vous prenez une photo

Whenever you take a picture this app send the hash of the picture (not the picture itself, preserving your privacy) to the OpenTimestamps calendar. The calendars will write a reference of this hash inside the bitcoin blockchain, proving the time of the photo in doing so. By later sharing the photo to the app you can update the receipt (without being dependant on the calendar information) and check the ots receipt
