If like me, some reader does not know what Swarm means, I guess it
refers to “hard disk of the world computer” that the Ethereum Foundation
envisions.  From my rough understanding, it is the way the Ethereum
cryptocurrency [1] stores its blockchain.

The only reference I am able to find – and I have not read it at all –
is this book of 287 pages [2]:

                           the book of Swarm

  (storage and communication infrastructure for self-sovereign digital
           society back-end stack for the decentralised web)

Well, fully ignorant on this topic, I am missing how its design
specifically targeting one blockchain dedicated to cryptocurrency could
be adapted to share Guix susbtitutes.  However, somehow, I am not
convinced that Guix should introduce some mechanisms to tackle some free
rider problems [3].

Could you be provide some details for helping my curiosity?
