These guys really managed to realize something special and unique. I think that this PDG project will be able to solve many things related to the calculations for the work or service performed. It is possible that many people come to use it.
I also liked their ideas about the possibility of the safe transfer of the work performed from the contractor to the customer. I think that it will be claimed.
the security issue today is very relevant. so, I think, the team has chosen the right idea. this is required for many technologies.
