Tue Nov 08 15:13:11 UTC 2016 <punkman> might be interesting if foundation set up trb testnet node and made a competition for double-spend against it
Tue Nov 08 14:56:46 UTC 2016 <funkenstein_> could make a deal though
Tue Nov 08 14:31:47 UTC 2016 <funkenstein_> you still need a preimage collision to spend the thing
Tue Nov 08 14:03:36 UTC 2016 <adlai> (trb would not eat a spend to that specific tx, because it's already spent, although you could create such a spend using the script 5121029b6d2c97b8b7c718c325d7be3ac30f7c9d67651bce0c929f55ee77ce58efcf8451ae)
Tue Nov 08 14:02:52 UTC 2016 <adlai> p2sh only needs a valid preimage, for trb to eat a spend
Tue Nov 08 14:02:16 UTC 2016 <funkenstein_> i mean, without a valid signature in the first output script
Tue Nov 08 14:00:03 UTC 2016 <funkenstein_> so am i understanding this right, consider TX 9c08a4d78931342b37fd5f72900fb9983087e6f46c4a097d8a1f52c74e28eaf6, alleged first 3xxx address in chain, you could craft a TX which moved this coin and would be confirmed valid by 0.5.3 and lower?
Tue Nov 08 13:55:57 UTC 2016 <adlai> one moment you understand this and i feel like an idiot spelling it out, but the next, you say that a confirmed transaction, with p2pkh outputs, but a p2sh INPUT, is not valid.
Tue Nov 08 13:54:57 UTC 2016 <adlai> once a p2sh input is spent to a p2pkh output, that output is no longer gavinola
Tue Nov 08 13:54:51 UTC 2016 <asciilifeform> if it is successfully send ~from~ a 1xxx, ~to~ a 1xxx.
Tue Nov 08 13:53:44 UTC 2016 <adlai> p2sh is a property of an output, which does NOT carry over into the outputs from a transaction spending it
Tue Nov 08 13:53:14 UTC 2016 <adlai> bitcoin are secured by a script. this is a particularly bad script, but it no longer secures them once they're safe in your wallet (or that of anybody else using eg p2pkh)
Tue Nov 08 13:52:08 UTC 2016 <adlai> if hitler loses his billfold on a morning walk, right outside your doorstep; all it contains is a metal clasp and bunch of paper, not even a single fingerprint; is it a valid payment from chance to your pocket?
Tue Nov 08 13:50:41 UTC 2016 <asciilifeform> and that these ain't proper coins, is too hard of a concept ?
Tue Nov 08 13:49:30 UTC 2016 <asciilifeform> adlai: the other extra rule: that this is in some way a valid payment.
Tue Nov 08 13:48:43 UTC 2016 <adlai> funkenstein_: p2sh is a script which says, literally, "hash the script and check the hash matches"
Tue Nov 08 13:48:15 UTC 2016 <funkenstein_> i still don't see how anyone would justify a tx which moves ps2h coin to an arbitrary address with no sig
Tue Nov 08 13:47:10 UTC 2016 <*> adlai doubts anybody who is openly affiliated with the mining industry would admit to having such a rocket ready
Tue Nov 08 13:45:09 UTC 2016 <adlai> isn't the right rocket for the forkkrieg a patch that, upon some trigger, begins trying to grab as much ex-p2sh coin as possible?
