CBOPRET creates trustless oracles, which can be used for making a synthetic cash settlement system based on real world prices;
|
|
|
|
|
|
|
|
0.5% fee based on betamount, NOT leveraged betamount!!
|
|
|
|
0.1% collected by price basis determinant
|
|
|
|
0.2% collected by rekt tx
|
|
|
|
|
|
|
|
PricesBet -> +/-leverage, amount, synthetic -> opreturn includes current price
|
|
|
|
funds are locked into 1of2 global CC address
|
|
|
|
for first day, long basis is MAX(correlated,smoothed), short is MIN()
|
|
|
|
reference price is the smoothed of the previous block
|
|
|
|
if synthetic value + amount goes negative, then anybody can rekt it to collect a rektfee, proof of rekt must be included to show cost basis, rekt price
|
|
|
|
original creator can liquidate at anytime and collect (synthetic value + amount) from globalfund
|
|
|
|
0.5% of bet -> globalfund
|
|
|
|
|
|
|
|
PricesStatus -> bettxid maxsamples returns initial params, cost basis, amount left, rekt:true/false, rektheight, initial synthetic price, current synthetic price, net gain
|
|
|
|
|
|
|
|
PricesRekt -> bettxid height -> 0.1% to miner, rest to global CC
|
|
|
|
|
|
|
|
PricesClose -> bettxid returns (synthetic value + amount)
|
|
|
|
|
|
|
|
PricesList -> all bettxid -> list [bettxid, netgain]
