16:50:13 | Taek: | This winter we will probably spend several hundred dollars heating out home |
16:50:56 | Taek: | If Bitcoin miners became efficient enough, people might be able to replace their heating systems with mining rigs |
16:51:13 | Taek: | all the heat that's normally an issue for data centers would be a virtue in a decentralized context |
16:51:25 | Taek: | but only in the winter |

17:07:46 | andytoshi: | link to etay/sirer 2ppow? i thought their proposal was trivially non-progress-free, i don't recall it being interesting or tunable so i guess i am thinking of something else? |
17:08:57 | andytoshi: | in fact, i thought asic-faq.pdf was a perfectly good rebuttal despite having been written several months earlier :P |
17:09:19 | tromp: | http://hackingdistributed.com/2014/06/18/how-to-disincentivize-large-bitcoin-mining-pools/ |
17:11:21 | andytoshi: | yeah, that's right... it's trivially not progress-free because there are two stages which both require work |
17:11:53 | andytoshi: | which i read as "they have not done even basic research into how pow works" and stopped reading there, phd or no this is layman crypto |
17:17:59 | tromp: | it's mostly progress free. way more than cuckoo cycle anyway |
17:18:40 | tromp: | after solving the 1st stage, you only do 1 signature+hash in the 2nd stage |
17:20:21 | tromp: | how would that give fast miners a disproportionate advantage? |
17:59:06 | andytoshi: | the 2nd stage involves many hashes because you are trying to get hash(sig) to be small |
17:59:57 | andytoshi: | oh, i see, if you use a unique sig scheme then it's ok |
18:02:49 | andytoshi: | i read it as deliberately using a randomized sig scheme to do a second pow |
18:03:15 | tromp: | no; it's meant to be a single deterministic check |
18:04:09 | andytoshi: | ok, my bad, i read and dismissed the scheme too quickly |
18:15:15 | gmaxwell: | Weird that they've still not updated their page to point out whats required to make the second a single check. |

22:10:43 | phantomcircuit: | will a transaction which has only 1 output value 0 with op_return be considered standard? |
22:13:02 | gmaxwell: | Yep. |
22:14:15 | phantomcircuit: | the limit is 40 bytes right? |
22:14:56 | gmaxwell: | Yep. |
22:15:17 | gmaxwell: | if you're just making a commitment, you might want to consider using the contract hash tool instead. |
22:17:32 | phantomcircuit: | gmaxwell, hmm interesting |
23:19:26 | phantomcircuit: | are transaction id's reversed in rpc calls? |
23:29:24 | tacotime: | um, depends on your implementation, but i noticed with bitcoind sometimes they were as compared to the raw tx. |
23:31:17 | tacotime: | does that have to do with the byte ordering when you push it off stack for a txin? never thought about it, but this is more #bitcoin-dev |
23:31:55 | tacotime: | ehm, that's not a script either, nevermind, it's just from a struct. |
