I think we first need to do some experiments to see if any of those claims can be justified. In general, the logic for when to use ERIS transports needs more thought. For one, I think it should be user configurable. I can imagine that certain users do not want to use decentralized substitutes at all. Users should be able to deactivate the entire ERIS thing. For the default, I personally think it would be ok to try and use ERIS. The only thing we absolutely need is a clean fallback logic that transparently falls back to getting the entire NAR by HTTP. Currently such a fallback is not yet implemented. -pukkamustard
