/*
make sure to broadcast deposit before claiming refund, or to just skip it if neither is done
*/
// included from basilisk.c

Tier Nolan's approach is followed with the following changes:
a) instead of cutting 1000 keypairs, only INSTANTDEX_DECKSIZE are a
b) instead of sending the entire 256 bits, it is truncated to 64 bits. With odds of collision being so low, it is dwarfed by the ~0.1% insurance factor.
c) D is set to ~100x the insurance rate of 1/777 12.87% + BTC amount
d) insurance is added to Bob's payment, which is after the deposit and bailin
e) BEFORE Bob broadcasts deposit, Alice broadcasts BTC denominated fee in cltv so if trade isnt done fee is reclaimed
