How does the blockchain technology apply to the real world service?

The same it applies everywhere? For instance, public ledger and fast transactions.

If I would like to have a blockchain technology on a supply chain service, which means under this technology, each block contains all the logistics information like storing a transaction from Singapore to Hong Kong right? So then it is just act like a database but just public can view it? then why should I necessary to develop such a service on blockchain but not continue using centralized database technology, only allow permission for beneficial stakeholders?

Please correct me as I am having a very messy concept on this topic right now.... Thank you~!

Bitcoin can definitely change how logistics are handled. But why would you want to make it decentralised? I wouldn't like shipping information or anything that I order on a public chain to be honest.Arent all the supply chain companies centralised already? What benefits would implementing blockchain bring? The supply chain will remain centralised anyway.

I personally don't see blockchains solving the supply chain tracking problem.

If people are unwilling or unable to keep track of data in traditional databases they will also be unwilling or unable to keep track of data using blockchains. If people are unwilling or unable to agree on which central database to use, they will also be unwilling or unable to agree on which blockchain to use. If at the end of the day you come to the agreement that a permissioned blockchain would do the job, you are very likely better of just using a traditional database.

Projects with lots of data (for example a suply chain) requires a lot of data to be stored on the blockchain. That would be very expensive.

That is why projects like OriginTrail develop their own "sidechain" (not exactly a sidechain in OriginTrails case) to store the data and only store the hash of the data to the mainchain.

There are quite some projects that tackle suply cains, I follow OT development so I can only say some words from their project. If you are interested in suply chains you should check it out. They will be launching beta network by the end of the week.

Hi Yodomaster,

First of all; I want to compliment you for thinking critically. It is a good way to learn.

In your specific use case (supply chain) I think you are correct. It would be better to have a database with permissioned access. Something of that sort is often called Private blockchain or Hybrid blockchain (mix between permissionned and permissionless).

The problem now in supply chain is that all different stakeholders hold different centralized databases, store different records and have their own modes of communication. If 2 parties store different records, which one is true? how are other parties in that supply chain able to judge?

Apart from cost and speed benefit (because everyone communicates in the same network; the permissioned blockchain or decentralized database) It also helps to agree on the same truth. All stakeholders involved with the shipment agree on the same status in the same ledger.

This is very general, but I hope it makes sense.
