I'm going offline until tomorrow, but you guys have my sincere thanks.
Ripper and vokain, I didn't officially set up a bounty, but I would like tip these two guys (maybe 3 BTC each) once I start tapping Exodus Address funds September 1st. Do you approve?
bytemaster needs a tip for his insane persistence, and d'aniel for actually describing the attack that bytemaster felt must exist.
After reading all bytemaster's posts: Wow! Bytemaster that 10BTC really was worth it you've really internalized what I was saying; and you're about to make 3 of it back! As I learned, sometimes you have to attack the same idea from 50 different angles before the person understands the point. I tried, but since dacoinminster accepted that his "GoldCoin" could fail but was willing to go forward I gave up. I think he was thinking "years" while I was thinking "as soon as gold/mastercoin rises 5%"... Kudos to d'aniel for finding that magic recipe.
Ok to business: 1 attack, 1 issue:
Attack:
1. register goldstream
2. create goldcoin based on goldstream
3. Wait...Let people buy into it.
4. inject bad goldstream data indicating gold's price has crashed.
5. buy a huge amount for almost nothing (escrow will be minting like mad to match gold's supposed price)
6. resume with correct gold data.
7. "Failed" underwater currency gets closed out. You get paid out of the escrow for your goldcoins -- essentially stealing the backing from the people who purchased goldcoins at real values.
(bytemaster, did you ever solve this "oracle" trust issue? -- point me to your latest spec)
Issue:
from "registering a data stream, point 5:"
Label = Gold\0 (5 bytes) (if a second Gold is registered in this sub-category, it will be shown as Gold-2)
Two people could independently issue bitcoin txns to create a new currency into the same block and so inadvertently use the same label.
