confirmations, like 100 or so 03:41 < belcher> "6 confirmations is safe" is a persistent myth 03:42 < belcher> iv heard most ASICs are actually underclocked to increase power efficiency, its possible for miners to overclock them and temporarily get a much larger hash rate if they want to try reversing transactions 03:50 < belcher> waxwing for malleability you could get the other party to sign many versions of the tx, one for each possible highS/lowS 03:50 < belcher> i wrote about it here https://bitcointalk.org/index.php?topic=303088.msg18149691#msg18149691 03:50 < belcher> it limits how many inputs you can use because the number of signatures you have to get is 2^number-of-inputs 03:57 -!- FASDFSF [~FASDFSF@unaffiliated/fasdfsf] has joined #joinmarket 04:01 < waxwing> belcher: huh, never thought of that. should just check the scripts tho', like you did for JM on the outputs (this time need to check the inputs), as long as that always works. 04:01 < belcher> how do you mean check the scripts? 04:01 < belcher> to choose which signature to apply? 04:02 < waxwing> well say the 2 of 2 is being watched in the wallet, watch spends from it, check the inputs for the secret. 04:02 < waxwing> the 2 of 2 which is the scriptPubKey for TX2/TX3 that is 04:03 < waxwing> that's the part that's most important for coinswap, to watch if the other party has spent it out from under you when they have the secret. 04:04 < belcher> yes ok 04:17 < waxwing> so had a chance to read gmaxwell 's comment above, does 'monotone' mean, in this context, that a script's validity only goes from invalid->valid and doesn't oscillate back and forth between them as global state changes? 04:19 < waxwing> i was thinking, what if a reorg occurs, but the number of blocks in the new best chain is shorter? i realize that is super-unlikely. 04:25 < belcher> unlikely but possible... 04:25 < belcher> it would cause a chain split.. since new nodes that join would reject the block 04:26 < waxwing> oh, why? new chain is best (most work) 04:26 < belcher> you need to mine very high difficulty blocks, so that fewer of them reorg out the longer chain 04:26 < belcher> then open a short on all the big bitcoin exchanges and you're done :D 04:26 < belcher> then again.. lots of mining power can already destroy bitcoin 04:26 < waxwing> yes, i was meaning that (and it's unlikely as we say) 04:27 < waxwing> only mentioned it due to the discussion of CLTV and monotonicity (if i interpreted it right) 04:27 < belcher> also we could be misunderstanding what gmaxwell said 04:27 < arubi> not high diff blocks, you might mine a secret chain right before a retarget that makes target lower, and only release it after a retarget that made the target higher 04:28 < waxwing> i was just musing whether the monotonicity argument against things like an 'expiration' script, might also apply to CLTV with block number, in such a scenario. 04:28 < arubi> might need to combine both chain length and absolute time to assert a healthy chain.. 04:31 < arubi> say 10 blocks were mined /and/ 512*9 seconds passed, but it's not always true :( 04:54 -!- belcher [~belcher@unaffiliated/belcher] has quit [Ping
