Prices CC would best build on top of the oracles CC, ie. to combine payments for multiple oracles and to calculate a 51% protected price feed.
|
||||
CBOPRET creates trustless oracles, which can be used for making a synthetic cash settlement system based on real world prices;
|
||||
|
||||
We need to assume there is an oracle for a specific price. In the event there are more than one provider, the majority need to be within correlation distance to update a pricepoint.
|
||||
|
||||
int64_t OraclePrice(int32_t height,uint256 reforacletxid,char *markeraddr,char *format);
|
||||
|
||||
Using the above function, a consensus price can be obtained for a datasource.
|
||||
0.5% fee based on betamount, NOT leveraged betamount!!
|
||||
0.1% collected by price basis determinant
|
||||
0.2% collected by rekt tx
|
||||
|
||||
given an oracletxid, the marketaddr and format can be extracted to be used for future calls to OraclePrice. This allows to set a starting price and that in turn allows cash settled leveraged trading!
|
||||
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
|
||||
|
||||
Funds work like with dice, ie. there is a Prices plan that traders bet against.
|
||||
PricesRekt -> bettxid height -> 0.1% to miner, rest to global CC
|
||||
|
||||
PricesFunding oracletxid, margin, priceaveraging, maxleverage, funding, longtoken, shorttoken, N [pubkeys]
|
||||
PricesClose -> bettxid returns (synthetic value + amount)
|
||||
|
||||
PricesBet -> oracletxid start with 'L', leverage, funding, direction
|
||||
funds are locked into global CC address
|
||||
it can be closed at anytime by the trader for cash settlement
|
||||
the house account can close it if rekt
|
||||
PricesList -> all bettxid -> list [bettxid, netgain]
|
||||
|
||||
Implementation Notes:
|
||||
In order to eliminate the need for worrying about sybil attacks, each prices plan would be able to specific pubkey(s?) for whitelisted publishers. It would be possible to have a non-whitelisted plan that would use 50% correlation between publishers.
|
||||
|
||||
delta neutral balancing of riskexposure: fabs(long exposure - short exposure)
|
||||
bet +B at leverage L
|
||||
absval(sum(+BLi) - sum(-Bli))
|
||||
|
||||
validate: update riskexposure and it needs to be <= funds
|
||||
|
||||
PricesProfits: limit withdraw to funds in excess of riskexposure
|
||||
PricesFinish: payout (if winning) and update riskexposure
|
||||
need long/short exposure assets
|
||||
|
||||
funding -> 1of2 CC global CC address and dealer address, exposure tokens to global 1of2 assets CC address
|
||||
pricebet -> user funds and exposure token to 1of2 address.
|
||||
pricewin -> winnings from dealer funds, exposure token back to global address
|
||||
priceloss -> exposuretoken back to global address
|
||||
|
||||
exposure address, funds address
