We used to say the same thing about Gigapedia (later library.nu) and had the same sentiment about Smiley (the admin).

And similarly about Grooveshark.

The truth is that, these types of things always come to an end. It is of utmost importance and urgency for the Sci-hub infrastructure to be made distributed and resilient.

This make me thing, could it be possible to set up a Smart Contract in some blockchain to achieve a similar thing? (I understand that this works by using user/passwords provided by some people, so it may not be feasible given the easiness to look at the information). That way the system will be very resilient given the nature of blockchain.

Nevertheless, I think I give more merit to Library Genesis. Even though the concept of Sci-Hub is very good, it is mainly a proxy... whereas Library Genesis actually is saving human knowledge.
