gleb> Did we think about private set intersection for lists of connected peers, and disconnect from peers my peer is connected to?

(crypto-related, Paillier is nice but not that germane) 17:01 < gmaxwell> I've never seen one that was sutiable for production use. (maybe some exists that are, but I've not seen them)-- usually they're a software engineering disaster, with no comprehensive tests (or no tests at all), thoughtless layering (E.g. socket calls intermixed with big num calculations), and little to no sidechannel resistance. 17:02 < gmaxwell> (I don't hold this against them, like 99% of what I've seen was written by academics as part of their publications, and I'm thankful they published code at all... but the code is usually more or less "what was required to write a paper on the subject" and it shows.) 17:03 < gmaxwell> If someone finds something that actually looks nice from the perspective of production use, I'd love to hear about it. 17:03 < bsm117532> gmaxwell: Agreed on all that. I'm trying to push the state of the art, because I fundamentally believe it will be part of this ecosystem in the future. 17:04 < bsm117532> I'm hopeful for amiller's work https://github.com/amiller/HoneyBadgerMPC but it's still early 17:07 < gmaxwell> Arguably the field of "what cryptosystem is best for this" isn't clear enough yet right now that its even worth the engineering effort to create something production ready. 17:07 < gmaxwell> like... by the time you finished it, there would be some newer hotter cryptosystem, and you'd need to start over, maybe only preserving some of the API and test design. 17:09 -!- tromp [~tromp@ip-217-103-3-94.ip.prioritytelecom.net] has joined #bitcoin-wizards 17:10 < bsm117532> Agreed. And I'm even confused as to how to know when a given protocol is even a candidate for being "productionalized".

Once you put real money behind it, shit becomes real, very fast. Bitcoin is advancing cryptography in a way it couldn't without it. 17:31 < gmaxwell> a little, I dunno, careful not to read too much into that. Like plenty of stuff gets real money put behind it and remains totally insecure for a long time. It's certantly more effective at getting it fixed then not using it at all. 17:32 < gmaxwell> but production use alone isn't a magic elixer than makes things secure. 17:33 < bsm117532> A refrain I keep repeating to certain teams in charge of keys... 17:34 < gmaxwell> I think really things will be secure only if they've had conscious attention from people with the right backgrounds and perspectives, ... and thats more likely to happen if they're used for something actually useful. But it's certantly possible for something to be a well engineered ship in a bottle, just as its not uncommon for people to run into full production use with barely working 17:34 < gmaxwell> disasters and pull it off for years (before all the money vanishes) 17:53 -!- spinza [~spin@155.93.246.187] has quit [Quit: Coyote finally caught up with me...] 18:02 -!- spinza [~spin@155.93.246.187] has joined #bitcoin-wizards 18:08 < bsm117532> Re: "Like plenty of stuff gets real money put behind it and remains totally insecure for a long time" -- there's a number of people in this space interested in active attacks.

(days at least). 19:07 < bsm117532> That's changing, albeit slowly. 19:07 < gmaxwell> and I don't even think that was visible on the market feeds for it. 19:07 < kanzure> another observation is how irrational the market is (note the value of garbage trash "crypto" projects) 19:08 < gmaxwell> kanzure: ehhh. If your hypothesis is that the market is irrational perhaps you should consider other alternatives. 19:08 < bsm117532> Yeah I think this is mostly driven by irrational investors who don't understand. 19:08 < kanzure> well i struggle to justify a million spinoffs 19:08 < gmaxwell> I think the market isn't irrational in investing in obviously broken stuff like iota, in fact. But rather the market is buying something different than what we're assuming they're buying. 19:08 * bsm117532 prices hype 19:09 < gmaxwell> For a lot of these things the market price isn't a "this is a useful/purposeful/secure cryptocurrency" the market price is "maybe something useful will be based off the ownership of this in the future" or other similar things. 19:09 < gmaxwell> or even "a bigger fool will buy this" 19:09 < bsm117532> Markets generally assume price is a proxy for everything else. 19:09 < gmaxwell> And history supports these sorts of theories. 19:10 < gmaxwell> so for example bcash (and esp bsv) you could look as a bet that craig wright really did create bitcoin and will eventually prove it. (among other things) 19:11 < gmaxwell> As that sort of hedge it's radically overpriced, as far as I'm concerned but considering how many people believe it's true or at least vaguely possible, it's almost surprising how low the price is... 19:11 < kanzure> even the greater fool theory can't support a million copycats 19:11 < bsm117532> And price is a proxy for it. Someone else did the DD, not me. 19:11 < gmaxwell> kanzure: well it can until there is enough, like how coingen largely killed the "take bitcoin relaunch with a premine and a new name" 19:12 < kanzure> coingen was killed because someone acquired it and killed it 19:12 < gmaxwell> but before coingen there was still hundreds of them. 19:12 < gmaxwell> kanzure: it served its purpose. 19:12 < gmaxwell> and yes, someone who'd been creating worthless altcoins bought it and let it die. 19:12 < bsm117532> With larger investors, more of them will do due diligence. 19:12 < bsm117532> Because no one will risk a retirement fund on this shit. 19:13 < gmaxwell> I am not sure many people aren't doing due diligence.
