How does the blockchain technology apply to the real world service? 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~!
Those who opt for blockchain to digitally store their private data consider that blockchain is transparent. Transparent in the sense that no single entity has the power to delete or alter YOUR private data at any given time. Essentially, instead of handing your files to a company like Amazon or Microsoft, you distribute it across a network of people all over the world. The cloud is shared by the community, and nobody can read or tamper with anyone elses sensitive data. In other words, you stay in control. This could also be useful in public services to keep public records safe, available, and decentralized.
