This project looks very promising for me.
I think the idea of robotization of delivery is great and it will have a prosperous future.
Do you develop only operating platform? Where do you plan to get drones?
SKYFchain project develops a unique decentralized platform, which will allow its users to get full and valid data on equipment.
Despite this seeming quite pompous, in fact it will be very easy. Distributed register based on blockchain, incorporated in the platform, will store all the data on technical conditions of drones and history of their usage from certification to technical checkups and passports.
