| 04:07:31 | petertodd: | Taek: re: domain separation, I posted a few weeks ago here how you can nearly make a blocksize increase be a softfork, because you can construct a transaction that looks like an inner node |
| 04:07:58 | petertodd: | Taek: however... you have to brute force something like ~48-64 bits to pull that off, soo... not terribly practical :) |
| 04:08:34 | orik_: | orik_ is now known as orik |
| 04:08:38 | Taek: | even 64 bits isn't that bad with today's ASICs, assuming only the miner needs to brute force it |
| 04:09:23 | petertodd: | Taek: right, so you've implemented a merkle mountain range :) one interesting thing there is ask yourself if you're 100% convinced that you can prove everything you might want to prove easily in a context independent way; see my mmr implementation here: https://github.com/proofchains/python-proofmarshal/blob/master/proofmarshal/mmr.py |
| 04:09:37 | petertodd: | Taek: yeah, OTOH, would make testing things in testnet a bitch :) |
| 04:10:05 | Taek: | oh right lol |
| 04:10:35 | petertodd: | Taek: oh, actually, I'll bet you the birthday problem might help... I was a bit too drunk to think of it when I wrote it up in #bitcoin-wizards :P |
| 04:12:17 | Taek: | are the logs the only place you've written about it? |
| 04:12:57 | petertodd: | Taek: yup! seriously, IIRC I'd just gotten home from a bar with friends :) |
| 04:13:20 | petertodd: | Taek: it's a seriously, seriously ugly hack though, lets be honest... |

| 09:36:21 | adam3us: | petertodd: you can make a blocksize extension (an size increase) by soft-fork. interestingly SPV clients might be compatible with a hard fork bitcoin block size increase also (they're just looking at log(n) paths anyway |
| 09:48:19 | gmaxwell: | (as an aside, it's 90 bits of griding, even accounting for 10 bits of meet in the middle, to do the node emulation in the bitcoin tree. If it weren't it would be a serious security vulnerability for SPV nodes. (I'd mentioned it in here prviously)) |

| 19:43:56 | petertodd: | gmaxwell: 90 bits? that doesn't sound right; a simple fix would be a soft-fork to prevent txs smaller than 65 bytes |
| 20:37:32 | arubi_: | arubi_ is now known as arubi |
| 20:43:44 | andytoshi: | petertodd: iirc the calculation was done in the logs somewhere here, it was a sum of like 15 terms |
| 21:08:24 | andytoshi: | maybe not :/ i can't find it anywhere ... was something like 32 to make version == 1, maybe 10 to get a valid locktime, 7 for ninputs == 0 or 1, 5 for noutputs ≤ 8, then the size byte of all the scripts had to be really small |
| 21:08:42 | andytoshi: | the rest had to do with getting an actual attack rather than just a valid tx maybe? |
