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?
Im trying to better understand blockchain and I cant seem to find the answer for the questions below:
In a blockchain, you would typically store only hashes and no real content such as names or any other text elements, right ?
I understand the blockchain is not hosted with a classical webhosting provider. But doe this mean that the chain is stored on every single computer or server connected to the blockchain and is being synced ? (or only computer that has some kind of software installed which connect to the blockchain)
What if the blockchain is 50 GB large ? Does this mean every single person will store this 50 GB large blockchain on their PC or smartphone ?
How does an application connect to a blockchain, by a port, URL, ID ?
