Which 20TB? The last projects or random?

It’s a bit ambiguous question:

A) If you are hosting the blockchain “at home”, then by definition you contribute to the consensus of the network and you are just hosting the blockchain. Self hosting becomes irrelevant as your node becomes part of the never ending non reputation party.

B) If you are are enabling people to host data ON the chain itself: Well, good luck on future technical interviews if you put that on your resume :P
