<s​hkeezy:matrix.org> how long should it take the gui wallet to sync

<x​c70xqns:matrix.org> 24 hours?

hey y'all

how's everybody doing? y'all know the news right?

<o​cean:matrix.thisisjoes.site> Ahhh Yes. The News...

what news?

<p​cre:monero.social> Richard Hearts son is all in on Monero: youtube.com/shorts/58b5K_wwXCI

<p​cre:monero.social> I found this library to build a chat bot for Jami. github.com/AmarOk1412/jami-rs

<p​cre:monero.social> I need to learn rust.

<p​cre:monero.social> Build a chat bot that sells amazon voucher for Monero maybe vise versa.

<p​cre:monero.social> Jami is inconspicuous and has been used a lot during the pandemic. People know it.

<p​cre:monero.social> However, a kind of reputation system is needed so that customers can trust the provider.

<p​cre:monero.social> Anyone who can't imagine what I'm talking about. Something similar to this, except that an Amazon gift voucher number is issued at the end.

<p​cre:monero.social> matrix.to/#/#mnp:monero.social

<p​cre:monero.social> + It will be peer 2 peer + end to end encrypted communication.

<d​readful13:matrix.org> Hello everyone, I am looking for a place to buy Monero in Brussels. Any idea on how to do so without KYC in person or online ? I can't trade more than 50€

<p​cre:monero.social> Use Bisq to buy Bitcoin and then exchange BTC to XMR - also on Bisq.

<p​cre:monero.social> bisq.network

<p​cre:monero.social> Haveno isn't ready - yet. i think. github.com/haveno-dex/haveno

<p​cre:monero.social> Be aware that Bisq and Haveno have a peer 2 peer protocol, similar to BitTorrent. If you accept an offer this is not a problem. If you make an offer, then you have to run Bisq 24/7. There are no servers.

<p​cre:monero.social> You could also buy Bitcoin with Relai sitting in Switzerland. 1000,- Euro without KYC a day.

<p​cre:monero.social> Then use Bisq to trade BTC for XMR.

<x​ero:matrix.lrn.fm> localmonero is over. what to use

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> fuck BTC

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> People on reddit said that you can buy LTC and then swap that to XMR

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> do not buy BTC it's high fees are bs

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> dreadful13: FWIW there was localmonero.co that would be much easier, but it seems that the feds shut it down

<i​gna:xmr.mx> this or TRX

<i​gna:xmr.mx> $1 isn't that high fee

<i​gna:xmr.mx> matrix.monero.social/_matrix/media/…oad/xmr.mx/CSRIKNQdOfGUpfbAmVQwMvNx

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> last time i was using it was 20 EUR for 5 EUR payment =-=

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> and arguably.. still is

<i​gna:xmr.mx> changes a lot

<i​gna:xmr.mx> compared to 1 week ago

<p​cre:monero.social> Please do not post hypothetical solutions.

<i​gna:xmr.mx> ?!

My domain would be $10-$15 and I guess I should avoid btc for it at all costs.

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> ye thus why i think that BTC is terrible choice

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> LTC -> XMT ain't hypothetical

LTC is accepted by some registrars that don't accept monero, ye

<p​cre:monero.social> Of course not - if you can buy LTC without any KYC anywhere.

<i​gna:xmr.mx> can't tell if this is sarcasm or not

How is the situation there, pcre?

<i​gna:xmr.mx> but yeah, its easy to get LTC without KYC

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> or like more people should be doing XMR ATM

<p​cre:monero.social> Everything is fine.

<5​m5z3q888q5prxkg:chat.lightnovel-dungeon.de> imma working on 5 atm to spread across the city

<d​otnetspec:matrix.org> Hi. Are there any online marketplaces that ONLY accept XMR?

<i​gna:xmr.mx> yes, moneromarket.io

<i​gna:xmr.mx> yes, moneromarket.io (or just check on monerica)

<d​otnetspec:matrix.org> @igna:xmr.mx: thanks, both are interesting ...

ATMs don't seem realistic - a givernment would get pissy over this.

They don't even allow KYCless BTC ones, XMR would be even more triggering

<s​yntheticbird:monero.social> what about ATMs that instead of taking bills take food

<s​yntheticbird:monero.social> buy a donut and sell your donut at the ATM

<s​yntheticbird:monero.social> then ATM owner will never be hungry again. win-win

<d​otnetspec:matrix.org> I'm currently considering building something similar to moneromarket, but I'm not sure how much demand there is for it ... do you have any opinions on this?

<s​yntheticbird:monero.social> afaik not a lot. when moneromarket was released, almost all the posts where drugs or porn. So hard for legitimate items to come through this mess. It took time for moneromarket to implement an nsfw filter.

<d​otnetspec:matrix.org> I'm a member of a Monero meetup but I haven't spent a lot of time inside the community and/or in chat groups like this ... trying to get a sense of how I could leverage on my development skills to build something within the ecosystem ...

syntheticbird, yhat is still a way to purchase XMR easily AF so would be banned. Also what to do with excess food? That seems like a waste of money for nothing.

syntheticbird, yes!! That is why I remember dismissing this entirely, because it was disgusting! Monero is above this)

<s​yntheticbird:monero.social> Not that I know of. I'm buing BTC then swaping to XMR atm.

<s​yntheticbird:monero.social> Idk bro give the excess foods to poor childs and make them work as slave. yk economic circle

<s​yntheticbird:monero.social> Yes really disgusting. moneromarket UI was a little old and first page was literally PH. I mean wtf

<s​yntheticbird:monero.social> Who would want to sell its items on this website

syntheticbird, that is impractical AF, just complications and not for some legal loophole.

<d​otnetspec:matrix.org> ? is this somehow controversial, off limits? :) ...

What controversial?

<s​yntheticbird:monero.social> Yeah I mean. I don't see whats wrong at slaving childs for the great crypto kingdom to arise /s

matrix dot org replies are like those threads where people edit the question after the response comes

<s​yntheticbird:monero.social> joke aside. I think its really impossible to make an ATM without KYC or legal regulation

Your suggestion is just overall stupid. It does not take advantage of some legal loophole, it just makes it hard/impossible for the seller to convert the income for money for no reason.

syntheticbird, EXACTLY.

<s​yntheticbird:monero.social> The food suggestion was a joke. Of course its stupid

<p​cre:monero.social> I like the idea of tradeing voucher for XMR. Amazon / Walmart / Mastercard /Addidas etc. It is just a number you can easy send digital.

<p​cre:monero.social> it is not secure.

<p​cre:monero.social> you need a web of trust

<c​trej:matrix.org> dont ask for off limit things in an official channel

<p​cre:monero.social> reputation system

<s​yntheticbird:monero.social> Haveno-like Amazon?

<p​cre:monero.social> Haveno is pretty much #1 choice for the next years to come.

<c​trej:matrix.org> no its not controversial, but how would your idea differ from moneromarket?

<p​cre:monero.social> not much

<s​omeoneelse495495:matrix.org> ceetee I think delay between instance is confusing you

<c​trej:matrix.org> oh right, forgot about that

<c​trej:matrix.org> nevermind then

<s​yntheticbird:monero.social> Since the core have API. I would just pray for a native interface or at least a web interface on top of Tauri.

pcre, wonder how easy it is to cash out such vouchers. Also, unlike prepaid cards, here we have these too!

<s​omeoneelse495495:matrix.org> no wry man

<s​yntheticbird:monero.social> Could we defederate matrix.org already ?

Matrix org being so big is probably my second biggest issue with Matrix, right after how it stores everything from groupchats permanently and I have not yet found a way to delete it safely.

<p​cre:monero.social> I don't know if can cash out a prepaid Mastercard (voucher). Do you know any more details?

<d​otnetspec:matrix.org> Hi. Is anyone online currently?

<p​cre:monero.social> @BlueyHealer I'll have to do some research on that.

<a​mbitiouslemming:matrix.org> Moneromarket has cleaned up a lot since then, and has run well for me. I primarily transact between precious metals and XMR there.

•plowsof> matrix dot org replies are like those threads where people edit the question after the response comes <<>> is there a message on the matrix side yet that tells people of the issue and suggests never to use matrix dot org?

<p​reland:matrix.org> Don’t know why I haven’t asked this question: what happens when mem_pool runs out of space? Considering that the max size of mem_pool is customizable by the node, is that a concern?

it prunes transactions with the lowest fee

nioCat yep its in the rooms description but most wont see unless theyre really looking for it. A bot that pm's users once (and only once) with some info if theyre using matrix org and comment here is not so intrusive but dont exist yet

hi everyone i was reading the other day quickly on some things regarding monero and thought i saw that there’s a new development in the works on top of ring sigs that’s more private

is that the case?

i looked around online and didn’t see anything but have the memory of reading that somewhere

didn't get an answer in 3 minutes so he left lol

Too late to post the recent fcmp++ blog?

I was about to so.....

Thank you!

<p​cre:monero.social> github.com/ranger/ranger Nice little file manager with vim control.

<a​remor:matrix.org> No concern. Your node stops tracking some txs. No biggie. Others still will. And mempool should clear at some point. And even if it doesn't, you can just send the TX again with a higher fee if your wallet notices that the older TX no longer is in the mempool that it is using

<s​yntheticbird:monero.social> What if the mempool the wallet is using have saturated and dropped the low fee transactions but the rest of the network relayed it ? If you send a new tx wouldn't it be considered as double spend attempt?

<p​epe86frog:matrix.org> I guess you could trace the gift card

<r​ucknium:monero.social> SyntheticBird: Yes it would. Reliable 0-conf requires the vast majority of nodes to have the same mempool retention policy if the mempool starts to get large.

<p​cre:monero.social> Possibly yes. But I see it as an interface to the "regulated" markets. It's a 56k modem. Yes - that's right.

<p​cre:monero.social> Just keep the chatbot in your contact list and if you need a voucher, order one. Just like you did with your drug dealer.

<p​cre:monero.social> You can order a fortune cookie here: matrix.to/#/#mnp:monero.social

<p​cre:monero.social> testnet XMR only.

<p​cre:monero.social> Try it. See how it feels like.

<r​ichie_rich:matrix.org> LocalMonero and AgoraDesk, prominent no-KYC exchange platforms, have announced that will be ceasing operations amidst a dwindling landscape for crypto privacy services. These platforms, which served as vital avenues for privacy-focused transactions during 7 years, are urging users to reclaim their funds as they prepare to shut down.

<p​cre:monero.social> Yes, that's really bitter.

<p​cre:monero.social> All the measures that are now being taken against legal entities will also be seen once the digital euro CBDC has been introduced.

<p​cre:monero.social> You all think I'm nuts for transmitting at 868 MHz, but you'll stop laughing as soon as the totalitarian regime is installed.

<0​x1zxq7896lp2zero:matrix.org> we are fully under attack now

I wonder whether Bestchange would last.

<p​cre:monero.social> Maybe, if it's small enough.

I am surprised it is still not shut down... Or at least the vendors on it aren't getting arrested one by one.

This is the govt I would expect to crack down on it - maybe all because crypto is not seen as a serious threat? Its legal status is grey, afaik the service providers are not allowed to accept it as payment but would need to check this.

<d​ave.jp:matrix.org> we are always under attack

<p​cre:monero.social> That is probably the right approach. It's a marathon and not a sprint.

<0​x1zxq7896lp2zero:matrix.org> yea now its escalating big time

<p​cre:monero.social> The day I solder together a motherboard to use Monero, that's the day the regime will realize it's pointless.

<a​remor:matrix.org> The currency has been designed for this

<0​x1zxq7896lp2zero:matrix.org> we need to use end-to-end encryption and network obfuscation by default instead of public surveillance platforms

Possibility of full DIY is what charms me so much about radio... But the amateur radio regulations had to ruin this by forcing you to basically disclose your name publicly and use no encryption >:(

<0​x1zxq7896lp2zero:matrix.org> we need to use end-to-end encryption and network obfuscation by default instead of public surveillance platforms

<b​asses:matrix.org> ?????

<0​x1zxq7896lp2zero:matrix.org> time to go darknet underground

<a​remor:matrix.org> SimpleX-Chat

just make an onion- or i2p-only IRC server, bruh

<s​omeoneelse495495:matrix.org> That is perfectly useless for a public group but ig simplex is pretty good

<s​omeoneelse495495:matrix.org> you read my mind

<0​x1zxq7896lp2zero:matrix.org> yep yep

aremor, what concerns me about Simplex is its centralization. Most people would realistically stay on the default central servers, and have not seen any public servers yet.

<h​elasse:linarphy.net> Just learn to use gpg and send armored gpg messages, bruh

So realistically you either selfhost or use the central ones, bruh

<0​x1zxq7896lp2zero:matrix.org> aremor: SyntheticBird45 | The monero.social relay bot best to not have any weak points or weak links

and if you selfhost, good chance that this is still going through the "mothership"

<s​yntheticbird:monero.social> tbf @BlueyHealer, you can host your own simpleX server

<p​cre:monero.social> gpg is also king.

helasse, that is very useful too, I have a gpg key on my website and encourage people to use it)

<p​cre:monero.social> They declared war on us.

syntheticbird, yes, you can, and it is apparently pretty easy. Point is NOT this. It's that most communications going through Simplex would likely still be going through the central servers.

<0​x1zxq7896lp2zero:matrix.org> simpleX chat and darknets are the way to go now

I really wish Simplex was more decentralized. I am yet to see big lists of public servers.

<b​asses:matrix.org> sounds like a common issue with all decentralized netowrks

<s​yntheticbird:monero.social> ig Bitmessage was the holy grail then

<b​asses:matrix.org> even matrix, most users are on matrix.org

<0​x1zxq7896lp2zero:matrix.org> lol

basses, yea, but the extent differs. Like, it is less noticeable with XMPP than with, say, Matrix.

<0​x1zxq7896lp2zero:matrix.org> yep

<0​x1zxq7896lp2zero:matrix.org> we need no central point of failure lol

<y​asabi:matrix.org> has there been any audit of simplex?

On On Simplex, seems like for now this is even worse than on Matrix.

<s​yntheticbird:monero.social> not that I know of

<b​asses:matrix.org> yes by trail of bits

<y​asabi:matrix.org> dope

<b​asses:matrix.org> but not full audit

<b​asses:matrix.org> full audit is soon this year

<0​x1zxq7896lp2zero:matrix.org> its the only by default and by design post quantum ultra private chat app

<0​x1zxq7896lp2zero:matrix.org> sadly

<b​asses:matrix.org> or the rest of of unaduited parts

<y​asabi:matrix.org> i've held off on looking at it since it's so new and didn't see any kind of validation of its privacy schema

I am following the news about it and interested where it goes. But for now not jumping to try it, I am still on imperfect yet trusty XMPP.

<y​asabi:matrix.org> knowing ToB has looked though inspires more confidence

<0​x1zxq7896lp2zero:matrix.org> yep sadly

<s​omeoneelse495495:matrix.org> I'm not bothered by centralized SimpleX. They have onion services

Yea, but still.

<b​asses:matrix.org> who tob?

Trail Of Bits.

<y​asabi:matrix.org> trail of bits, sorry

<y​asabi:matrix.org> they're a reputable source

<s​omeoneelse495495:matrix.org> Not gonna lie poor BlueyHealer is having a break thx to matrix.org delay

?

wdym having a break?

<s​yntheticbird:monero.social> Your message don't pass through

<s​yntheticbird:monero.social> since m_relay is monero.social

Huh? I do see some coming from matrix.org.

<b​asses:matrix.org> asked them why pick trail of bit instead of cure53 they replied with "they get into code more"

<s​yntheticbird:monero.social> everyone chatting rn is matrix.org

<s​yntheticbird:monero.social> Yes, we receive matrix.org messages in real time but they receive monero.social messages with 10 minutes delaye

lol

<y​asabi:matrix.org> there's also Briar which is not as well known but has been around for years and was audited by Cure53

<0​x1zxq7896lp2zero:matrix.org> we need i2p and even new one (veilid)

<0​x1zxq7896lp2zero:matrix.org> too

yasabi, yeah, know this one! But last I saw, desktop version was not fully-featured.

<p​cre:monero.social> It would be a good start if we could get used to decentralized software. Monero could also be hosted with radicle as a replacement for github.

yasabi, like, it effectively could not work over Tor because it lacked bridge support.

<s​yntheticbird:monero.social> Don't you have proposed radicle like 6 times since you joined ?

<p​cre:monero.social> i2p ++

i2p is underrated

<b​asses:matrix.org> if you want something on par with simplex but Tor only cwtch.im

<y​asabi:matrix.org> i don't believe Briar's Rendezvous Protocol is quantum-resistant tho, and it's designed more for small-scale groupchats than large chatrooms

<s​yntheticbird:monero.social> i2p is underrated now that i2pd is a solid thing

<b​asses:matrix.org> but more dead and unusable UX

<p​cre:monero.social> i know - sorry.

<y​asabi:matrix.org> yeah Cwtch is interesting, i follow one of the developers, but yeah super small project

Would look at that too, have only tangentially heard of it for some reason.

<0​x1zxq7896lp2zero:matrix.org> cwtch and onion-share are good too (well basically same/similar lol)

Kinda concerned that onionshare is in-browser JS, seems like anyone with a link can join a chat there.

<s​yntheticbird:monero.social> I love JS

<s​yntheticbird:monero.social> long live JS in tor browser

<s​yntheticbird:monero.social> as long as you trust the host

I really wish Briar was full-featured on desktop, I really would not want to trust a phone with my messaging.

JS in Tor is cursed

<0​x1zxq7896lp2zero:matrix.org> for start we need to abandon irc for full end-2-end encrypted groups chat routed by tor/i2p/veilid

point was more in that anyone with a link can join

<s​yntheticbird:monero.social> Still reliying on PHP in 2024 is cursed and cringe

What I like in Simplex are one-time invite links, that is cool.

<h​elasse:linarphy.net> In a whonix VM

<0​x1zxq7896lp2zero:matrix.org> We are Totally Underground "Now We Fight You" Phase

<s​yntheticbird:monero.social> I love how 0x1zxq is ego tripping in 3 channels at the same time.

<s​yntheticbird:monero.social> I'm all for changes but core won't change unless you make an issue on github

Also Briar had a Mailbox for always-online use, but last I saw this was for an "old phone"? That is weird, phones are not even supposed to be left on a charger 24/7.

<p​cre:monero.social> I even made a forecast on radicle + Monero in 2018 and provided it with a Monero timestamp so that I can prove it.

I wonder if they have a version that can be run on something like an SBC.

<p​cre:monero.social> SyntheticBird: I even made a forecast on radicle + Monero in 2018 and provided it with a Monero timestamp so that I can prove it. The day the Monero dev team will use it i can send you the proof.

I do host Conduit btw, I just don't know what to do if its message and media storage gets too big. I guess media I can sorta clean out one by one, but messages are in weird files that I could not safely move/delete.

<3​21bob321:monero.social> Different to dendrite ?

Yes.

Conduit's in Rust.

<3​21bob321:monero.social> Operates the sams

<3​21bob321:monero.social> Same*

Haven't tried Dendrite, so idk if it's similar.

Synapse does have options for storage cleaning and it frustrates me that Conduit doesn't. At least apparently there are plans.

<3​21bob321:monero.social> Dendrite has issues when the room upgrades that are using synapse.

<3​21bob321:monero.social> Ok one uses facebook/rockdb and other uses postgres

Facebook?

I don't get the reference. The default is rocksdb and the other is sqlite.
