BitUSD hype and its freaky price discovery lead me to some thoughts.
What if Peercoin would have multiple PoW diffs with different coinbase maturation times, f.e. 3 parallel diffs with 1 day, 7 days, 30 days respectively?
Miner/pool choose which one to mine.
Could diff changes/correlations be a base for price prediction, stabilization, discovery? If yes then we need opcodes(flags?) to make transaction inclusion in block conditional(f.e. diff3 > diff1 & diff2 > 200M ). This could bring far better price discovery mechanism than pegging(???). Since PPC security doesn’t depend on PoW i think that community consensus over changes would be quite easily reached.
Simple output script:
if diff3 > diff1 & diff2 > 200M
HASH160 EQUAL HX CHECKSIG(pubkey_b)
if diff3 <= diff1 & diff2 > 200M
HASH160 EQUAL HX CHECKSIG(pubkey_a)
(this script would require third party to hold X and publish it only if both sides of this ‘betting’ include their bail-in TXs in the blockchain)

Or create sidechain with advanced scripts.
