I believe I have a decent understanding of how Bitcoin works, but sometimes when I read news I stumble upon "the blockchain technology" - blockchain for banks, blockchain for medical records, blockchain for real estate and so on. From my understanding, most of them are private blockchains (correct me if I'm wrong), but when I tried to find some info on how those private blockchains work, I didn't get much. So, I have some questions:
1. How do they work? How blocks are organized? Are there any miners? Are they at least slightly more decentralized than traditional solutions?
2. Why blockchain? Does it solve any problems? Is this more efficient than traditional solutions? Are there any benefits for customers?
The point here is simple. There is no such thing as private blockchain. It is a scam. It is just a simple DBMS. They cannot afford the structure that is required and needed to maintain a real blockchain. Bitcoin blockchain was built by the world community. Pooling all the needed resources to keep it running for eight straight years. The private sector is not going to do that. It is expensive. Again private blockchain is a scam. You cannot find answers because if they answer your question the scam will be uncovered immediately.
