This is gonna be a bit off-topic, but still talking about park rates and just to clarify its protocol rules:
From the investors POV, how do park rates work during park length?
1) Do they work like "Fixed rate bonds" which have a coupon that remains constant throughout the life of the bond?
e.g. blockchain shows 1yr length, 12% pa => investor parks 100 NBT; after 1yr he gets back 112 NBT unparked no matter what subsequent changes in park rates might be during his NBT parked time.
2) Do they work like "Floating rate notes" (FRNs, floaters) which have a variable coupon that is linked to a reference rate of interest?
e.g. blockchain shows 1yr length, 12% pa => investor parks 100 NBT; after 1yr he gets back 100 NBT (principal) unparked plus (previously) unknown interest depending on the median park rate voted for that whole 1yr invested period.
P.s. I think it's important to clarify that details before advertising this offer beyond this forum...
