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
