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 [1] with discussion at [2].
Based on these, Grin also has a rough design for payment channels at [3].
Beam included relative lock heights in its recent HardFork [4] and has
a payment channel design at [5].
