After registering your music in your Soundreef profile, you just need to select the "Actions-->Certificate" tab for a given song in order to start the notarisation process.
The blockchain notarisation will be completed within a few hours. It is confirmation that the song exists at a determined point in time and is considered - at the precise registration date and by Law - a proof of existence and ownership of your works.
The registration does not imply any kind of protection requirements assessment, in accordance with the Copyright Law. Nor does it imply any acknowledgement on the matter. It does provide the possibility to present a definite proof of existence of your works, in case a potential copyright infringement case may arise.
