Origins are lowered into “fixed-output derivations”.  They’re
“fixed-output” because their content hash is known in advance, and thus,
the method you used to produce them doesn’t matter (info "(guix)
Derivations").

So you could specify an origin with ‘bittorrent-fetch’ (to be written)
instead of ‘url-fetch’.

HTH,
Ludo’.
