Data removal and blockchain

[Alexey]

Is it possible to link the uploaded data with the mined block hash value?

Storing data on blockchain is too expensive and inefficient as for upload and for the access. The only small chunks of data can be stored on blockchain and also in most cases they are immutable, i.e. you can’t delete or edit it. To make change you must generate the next block with that change. It’s not fast. And also the size of the blockchain will include all world data, at the moment it’s greater than 460 Exabytes.
