How does the blockchain technology apply to the real world service?
In the real world business blockchain technology secure business transactions, prevent thefts, ease and accelerate transactions, reduces faults without the need of third party
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?
Yes, it does act like data base but the info can be lock away on block chain ledger(public view as you said) and once that is done only people that have smart keys can access their information.
