Satoshi Proof APK

Latest update [menu]

- Now 100% written in Kotlin
- Smaller ( no more use of bitcoinj for address calculation )
- Minor UI improvements

Description [menu]

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

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

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

This app is licensed GPLv3 - you can find the sourcecode on github: https://github.com/ligi/SatoshiProof
