Not Allowing Miner to Read the Data in the block


#1

Hello,
i’m currently working on the topic blockchain for my mémoire.


Even if transparency is an advantage of the blockchain, it is also a problem for company that want to use blockchain but can’t affort showing their data.
However they like the security provided.


Here is my question
could we consider a blockchain used by a company where miners help secured the chain with their computer power but can’t read the data in the block ?


it seems to me that not allowing access to the data in the bloc is an obstacle to "mining/securing’ the chain but i would like to be sure about it.


I thank for your help and apologize for my english level
