Many businesses prefer to control their own data centres (servers) - they know where it is, and who is "responsible" for it.
The problem is: when hacked, their data is protected by "encryption".
With CORA, "not knowing" is far better. Even if the corporate server is hacked, they cannot get the data, because they don't know where the rest of the CORA blocs are stored. It really is that simple (from a non-technical perspective - the math and technology is, slightly more interesting).
