Some discussion about lightning and relative time locks in the context of Mimblewimble on the Bitcoin dev mailing list: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2019-September/017309.html
However, I believe that Lightning and similar offchain protocols are not possible on MimbleWimble, at least if we want to retain its "magical shrinking blockchain" property.
I do not believe it is the lack of SCRIPT that prevents Lightning-over-MimbleWimble, but rather the lack of relative locktime, which seems difficult to validate without knowing the individual transactions and when they were confirmed.
Are these assertions correct? I was of a different understanding.

MimbleWimble can easily incorporate relative lock heights, in addition to absolute lock heights. Grin and Beam have included the latter since launch. Grin's proposal for relative lock heights is at  with discussion at . Based on these, Grin also has a rough design for payment channels at . Beam included relative lock heights in its recent HardFork  and has a payment channel design at . regards, -John  https://github.com/antiochp/grin-rfcs/blob/relative_lock_heights/text/0000-relative-kernels.md  https://github.com/mimblewimble/grin-rfcs/pull/19  https://gist.github.com/antiochp/e54fece52dc408d738bf434a14680988  https://github.com/BeamMW/beam/releases/tag/beam-3.0.5654  https://docs.beam.mw/laser_beam.pdf
Andrew not really selling MW there -
Historically, this whole adaptor signature business came out of mimblewimble and in particular the question of how to add scripting to mimblewimble. As soon as I came up with this idea, I brought it to bitcoin and forgot about mimblewimble. As soon as I could do it with bitcoin, I ran away.
As part of the tx building research I’m doing, I’ve collated the most relevant papers I’ve come across in one place:
Very much a work in progress, contributions are welcome.
2.1.0-dev.1to reflect the upcoming 2.1.0 release. So if anyone wants to help test some early stuff out then please build and run the grin node from master - https://github.com/mimblewimble/grin
2.0.0) and hope to keep your db data then I would hold off testing master right now. Or test on a new fresh node only.
