01:30:38 -xmr-pr- > https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/158
08:05:39 <rehrar> so diego.com is available for purchase. It costs $300,000.
08:05:44 <rehrar> Would somebody like to chip in and help?
08:46:12 <fluffypony> I can send you testnet Tari
08:49:10 <needmoney90> Rehrar I just looked through my couch cushions and found you $1.38
08:49:19 <needmoney90> Good luck
12:03:30 <dEBRUYNE> sethsimmons: Have you played around with the Haven stablecoin yourself?
12:03:37 <dEBRUYNE> Afaik you need to burn Haven in order to get xUSD right?
12:13:42 <sethsimmons> Yeah, I've been involved since they launched the testnet, and participated heavily in the stagenet
12:13:51 <sethsimmons> Have been running a node for a while as well
12:14:09 <sethsimmons> It's... pretty amazing, honestly, and I'd love to see something similar built on Monero
12:14:22 <sethsimmons> I doubt the burn/redeem mechanism would fly around here, though
12:14:45 <sethsimmons> But an overcollateralized version with liquidations would be interesting, or something entirely novel
12:15:26 <sethsimmons> I was concerned at first why they chose to build on Haven instead of just on Monero, until I realized their implementation would never fly on Monero.
12:16:41 <sethsimmons> The biggest pitfall is the requirements of oracles, of course, and will be the pushback they get from practically everyone.
12:16:41 <sethsimmons> The implementation appears sound, but it still relies on Chainlink oracles for all pricing data, which is then embedded in blocks, and lockouts occur on conversions to help avoid gaming the system.
12:17:00 <sethsimmons> Sorry for the novel, dEBRUYNE 😅
12:28:50 <sarang> I thought they were using CLSAG for conversions now
12:29:11 <sethsimmons> They are IIRC, but it's via a burn/redeem model
12:29:19 <sethsimmons> You have to burn XHV to mint xUSD, and vice versa
12:31:52 <sarang> In what method?
12:32:23 <sethsimmons> Can you elaborate? Not sure what you mean :)
12:32:57 <sarang> How do you burn the XHV in their transaction model?
12:33:11 <sarang> Is it using a known amount?
12:33:35 <sethsimmons> You burn XHV proportional to the xUSD amount you want to mix, and pricing is pulled from recent blocks
12:33:39 <dEBRUYNE> I think it uses an oracle to gauge price
12:33:50 <sethsimmons> That pricing is provided by Chainlink oracles, and embedded in blocks by miners/validated by nodes
12:34:27 <dEBRUYNE> <sethsimmons> I doubt the burn/redeem mechanism would fly around here, though <= Why wouldn't it?
12:34:58 <sethsimmons> It means that the XMR supply would float and be unpredictable
12:35:36 <sarang> Ok then it's using the CLSAG method I understood them to be using
12:35:58 <dEBRUYNE> Well it would float insofar as it would be possible to decline
12:36:04 <dEBRUYNE> There is still an upper bound as far as I can see
12:36:08 <dEBRUYNE> One cannot create xUSD out of thin air
12:37:16 <sethsimmons> Yes, there would always be an upper bound proportional to the USD price of XMR
12:37:27 <sethsimmons> That's the max liquidity available for conversion
12:38:02 <dEBRUYNE> How do they measure the amount of xUSD outstanding by the way if amounts are encrypted?
12:38:21 <sethsimmons> Thats a question I've asked before, but can't remember ATM
12:38:24 <sethsimmons> Let me find the response
12:41:07 <sethsimmons> "Yes that’s correct. Transactions have been extended to include amount_minted/burnt in plaintext while the commitments are still used to validate. It was felt this visibility of supply was more important as a measure of ecosystem health than the loss in privacy it necessitates."
12:42:16 <sethsimmons> My biggest concern (beyond oracles) is the potential leakage around minting
12:42:23 <sethsimmons> But I understand their design decision overall.
15:27:09 <gingeropolous> so, do we have established liaisons with major exchanges, or do we just send floods of emails when updates are a coming?
15:37:32 <dEBRUYNE> Bit of both afaik
15:54:27 <sgp_> mostly flood of emails tbh
15:58:25 <xmrscott[m]> Yeah, technically there is a mailing list for these kinds of announcements, but I don't know how many services/exchanges are subscribed to it
16:00:03 <sarang> Has it been used reliably for recent upgrades?
16:00:14 <sarang> (I should probably subscribe...)
16:03:26 <xmrscott[m]> @freenode_Lena37:matrix.org: Typically  the Coffee Chat is posted about up to a week in advance here: https://github.com/monero-project/meta/issues
16:11:14 <xmrscott[m]> If you want to post/suggest a topic, you'd do it on the issue when it's created
16:15:38 -xmr-pr- [meta] SarangNoether opened issue #491: Research meeting: 29 July 2020 @ 17:00 UTC

18:51:52 <selsta> 18:00 <sarang> Has it been used reliably for recent upgrades? <-- yes
18:52:02 <selsta> also you should be able to see the archive
23:17:13 <kinghat[m]> why does telegram auto download files and photos by default from every chat you are in?
23:17:32 <kinghat[m]> isnt that a fairly large security risk?
23:18:46 <jwinterm> I mean, it's basically a giant vehicle to push scams, so...
23:21:00 <kinghat[m]> i mean if it wasnt, wouldnt that be a security risk?
23:21:22 <jwinterm> probably I guess
23:21:22 <xmrscott[m]> Narrator: It is
23:22:56 <xmrscott[m]> You can at least turn it off
23:23:08 <xmrscott[m]> Not that that's much comfort
