It is a nice service, maybe useful, and I think it is also cheaper than the others that do the same thing. However the blockchain has no legal value under the government courts, so you cannot "send notaries on vacation".
Thanks! Well, depending on what kind of service you wanna replace it's actually legally binding.
For example, private documents can be easily stamped using our service.
And anything creative (music, art, etc.) as well.
Anyway, nice job.
