I need to actualize a piece chain based application for transport industry.

Lets take an illustration/situation , we have to transport a few things which are temperature touchy. For this situation the manufacturer,transport organizations and buyer are the gatherings and installment will be done when the concurred temperature kept up all through things travel from maker's distribution center to buyer's stockroom.

All through the adventure, the temperature can be see/observed by means of a versatile application.

Presently the issues I have

Does every one of the gatherings have to their own particular piece chain server/benefit blockchain where they kept up the information or it will be a brought together area? Just the included gatherings can get to piece chain server/benefit.

How does the concurred temperature will be gone into the record? That is to say, will every one of the gatherings will enter the information or just a single gathering will enter the information and lay will concur on that.

On what condition/circumstance, it will be considered as transaction is begun and finished?

How all gatherings will approve the information?
