<milas900:matrix.org> In monero cake wallet it just generates new monero address for you when you exchange from ltc to Xmr right ?

hopefully, haven't checked :) would be stupid not to right?

I loke how I can use the same wallet on both PC and android

dont know how it really compares to the default wallet feature wise

sure it's nice to have other coin support etc usability but its a legit fear that might mean the XMR wallet isnt really behaving optimally in that kind of generic wallet...

<tsjk:matrix.org> Is there a particularly efficient way of consolidating amounts in many diverse addresses?

consolidating amounts in many addresses?

to what? one address?

<tsjk:matrix.org> Or do I just send all to a new address in, say, feather?

<tsjk:matrix.org> Cindy: yes

are you talking about subaddresses or regular addresses

<tsjk:matrix.org> I wish I knew. They are coinbase txs. :)

so you're talking about consolidating all the coinbase outputs?

<tsjk:matrix.org> Yes

or just.. are you mining to many seperate addresses or something?

ah

yes, you can just send all the outputs to yourself

sweep all the outputs to yourself, which will merge them all into one

<tsjk:matrix.org> Aight. I remember I read something a long time ago that there was a particularly clever way if one ran ones own node. But I recall neither the motive nor anything else.

<tsjk:matrix.org> Cindy: Thanks!

honestly, you don't need to run your own node for this one

unless you have a LOT of outputs to use

restricted RPCs have a limit on how much outputs you can have in a transaction (to prevent DoSes)

<ofrnxmr:xmr.mx> Cindy: No they dont

oh?

i could have swore

sorry

<ofrnxmr:xmr.mx> The limit is 100kb one way or another. About 146 inputs

<tsjk:matrix.org> idk what a lot is

what ofrnxmr said

<tsjk:matrix.org> maybe 200-ish payouts

<ofrnxmr:xmr.mx> Feather wont create multiple txs when doing a clnsolidation, so youll have tk use another wallet for that (iirc)

<tsjk:matrix.org> so, more than 146

or just split it yourself

make one TX with 146 inputs, and another with the rest that is left

the problem is you'll end up with 2 outputs, rather than one output

unless you refer to the output that was created by the earlier TX

<ofrnxmr:xmr.mx> The main reason to use a local node is that finding decoys is slow, and if it takes too long thr wallet bails out

<tsjk:matrix.org> Aight. Guess it was more complicated than just clicking a button. I'll read up. Thanks for the hints.

<ofrnxmr:xmr.mx> Its not more complicated than clicking a button

<ofrnxmr:xmr.mx> Just sweep all to yourself

<tsjk:matrix.org> The sweep-output thingy in feather then?

<ofrnxmr:xmr.mx> Better to sweep to a new wallet or to a subacccount, so that youre not re-consolidating already consolidated funds

<ofrnxmr:xmr.mx> @tsjk:matrix.org: Use gui or wallet-cli

in GUI, it's pretty simple

copy your primary address, go to send, paste it as the dest, click the infinity button

and send

<tsjk:matrix.org> Okidoki. I'll try that! Guess I'll need to import the seed to the gui. But that's no problem. I'll do that and see. Thanks

ofrnxmr: does GUI let you switch accounts in the same wallet?

Cindy: yes

neat

It makes you think your wallet got drained until you realise you're in the wrong account :D

your wallet has nothing: O_O

you were in the wrong account: :)

your wallet actually has nothing and someone swept it all up: O_O

time for some upgrades!

am5 socket here i come

What about DDR5 RAM though, have you stocked up in advance?

It's not like I could've stocked up on it even if I wanted to.

sech1: i'm glad that i bought storage that i did not need 6 months ago

Thankfully 16 gigs is more than enough for me, and by the time I can afford to upgrade, AI may not have as much money to throw around...

they looked like good value at the time, looks like a genius move now

But storage - yeah. That I could've used.

the 2tb nvme drives that i bought 6 months back have damn near doubled in price

F

I haven't filled up even my 512 SSD + 1 TB HDD, but in hindsight should've bought another SSD. I can't leave the HDD plugged into my Raspberry all the time because I'd need it to be noiseless, and the SSD is getting full...

yeah ima just have to suck it up and pay cpu prices for some ram

is uh matrix doin something weird?

no

why?

i can't login on element

you tried another client?

tryin the web client. monero.social won't work when i put it as the homeserver

The irc-matrix birdge is also down

sgp save us

yeah monero.social must be down

yes, back end admin looking into this 🙏

Hi there. Good to know you guys all alive!

16:50:42 <AlbertLarsan68> The irc-matrix birdge is also down

yeah, it goes via monero.social

Hey everyone! I'm new here and I tried joining the monero:monero.social Matrix channel (and others listed in getmonero.org/community/hangouts), but for some reason neither Cinny nor Element can join it. Cinny fails with "MatrixError: [502] Failed to fetch alias" while Element just hangs. Is the Matrix server still working? Of course, I'm happy to use IRC, but the Matrix error looks weird

matrix monero.social is down

HTTP 502 mostly means it couldn't contact backend

yay

matrix-free day

woohoo

Oh. Will it come back online?

18:09:14 <@plowsof> yes, back end admin looking into this 🙏

Ah, great. Thank you!

also btw, why are there public monero nodes that only work in HTTP

(not HTTPS)

aren't people worried about DPIs?

or maybe setting up monerod to use HTTPS is hard

I wonder if this counts as "DPI" given that it's just reading plaintext. When I think "Deep", I think "figuring out whether this TLS connection is real or hiding a tunnel inside it".

DPI also includes reading into what's inside the packet, determine what kind of service it is for

and deserializing info from it

just look at wireshark, it's an example of a DPI

Cindy: there are issues, but if you are using it to sync + send txs via tor, you are mostly fine

though as always, a bug in how wallet handles this can make issues appear as the most recent one shows

and remember "fine" is relative

Cindy: Almost everything sent to and from a node is public anyway. The only privacy issue is its IP address origin.

Most node SSL certs would be self-signed. They can be swapped out by a man in the middle, theoretically. There is SSL cert pinning to defend against that AFAIK.

I run a public node and don't use an SSL cert. You can connect with the same node through my onion service. That sort of is like an SSL cert.

> That sort of is like an SSL cert.

unless you do ssl cert pinning, Tor is stronger than pure SSL with public certs

it'd make headlines but a rogue public/country CA could issue a cert for the node one, unless you pin to the pubkey/cert (which Tor onion address pins to pubkey)

Rucknium: yes i know

but the IP address thing is what i'm talking about

you can match subscribers up to the TXIDs they sent

IIRC RavFX switched his Monero nodes to use SSL only.

DataHoarder: is it okay to "encrypt" the spend and view key using a XOR cipher?

XORing the keys with hash function outputs

xor cipher means nothing

don't invent own crypto please

Crypto is one of the only space where the NIH syndrome is the worst thing ever

you can store spend/view key encrypted properly, and pubs in the open (it's the main address on legacy wallets)

encrypted properly requires space for the nonce

and other cipher stuff

yes

you can use pubkey as nonce

they can be verified. but straight hashing or password schemes you think of just ad more issues in the future

i figured not adding a MAC either

just verifying the decryption by multiplying the private key by the basepoint and comparing public keys

derive key using PBKDF2

i was thinking of argon2é

then encrypt with a nonce (which might as well be the pubkey)

argon2*

but sure

argon2 is a function

PBKDF2 is a method to use the function

argon2 here being the PRF part

i see

if you didn't have a nonce

someone can build a rainbow table

either for the bruteforce or encryption

nonce for the hash function?

i mean key derivation function

kdf

the key is unlikely to be used more than once for encryption tbh

so i don't need nonce in the encryption algorithm

someone will use password2 as password

yes, but i meant the derived key

which will have nonce applied

But yeah, if you can have the nonce on the kdf that should be relatively ok. You also want a scheme that has them do the full derivation to check, not fast checks where only partial outputs can be extra ted

Extracted*

For example if you used raw SHA3 you can skip some sponge extraction steps to do quick 64-bit checks

i want to save as much space as i can

Also think about: what if the pubkey has been lost :)

You want to save space at the cost of future usability or adding custom complexity

Tbh. Have the spend key be sealed inside a fold

doesn't an address have both public keys serialized in it?

i wanted the gift wallet to take up 1/4 of an A4 paper, but after seeing how massive the QR code was, and how unrealistic it would be to expect most consumer printers to have the amount of DPI required to print it out without ruining the code

i had the QR code take up like 2/4 of the paper

below the whole info above

lemme upload something rq

this is the whole A4 paper lol

(also yes, placeholder QR code, but an actual one is much much larger)

21:42:59 <Cindy> doesn't an address have both public keys serialized in it?

yes

the QR code can be smaller

you can also have it within the layout

just think in bytes if you are encoding raw stuff

i'm encoding a whole URI

containing 1) address, keys, TXIDs

i mean address and keys already make the QR code massive, like version 18 or something

TXIDs would push it to version 25

split it on multiple, too

you can do multi qr encoding

this is with high error correction btw

oh really?

and as said, txids are not needed

you only need the global output index/amount which amount = 0 on all relevant recent hardforks

global output index is an uint64, which gets varint encoded to be much smaller

they are at like 147053899 atm

does the URI allow encoding global output index

with these values you can make RPC calls to get the specific transaction outputs (txid : local output id tuples)

the standard doesn't

I have no idea about what URL you are targeting

monero-wallet URI

it only lets you encode either the block height or list of TXIDs

why are you encoding txid here

yes that

this is to generate the wallet restore height

you can pass a height instead

or leave empty to scan since monero inception

to make it much faster to scan

this is not to scan specific txids

yes, then you just pass an integer as height

txid will just lookup which height that tx was included as part of

did you misunderstand the meaning of that field?

i thought it would lookup each of the TXIDs and then scan the blocks they belong to

nope

wait

it does

"Absence of height"

it was me all along who didn't read

ha

you see

i knew it :D

tbh

it would be dumb to implement it if it didn't do that

just set height to the first tx

yeah this QR would be massive

dedicate an entire A4 for it :)

you also want to be able to support depositing?

if so, just setting the initial creation height works well

i mean, setting the height would make it waste more bandwidth searching from the creation of the gift wallet to the current block height

before it can send anything

that ain't fast

if you constraint to a single txid maybe

but realistically this would be a multipart qr

where you scan wallet details

then txid sets to scan

but ofc. not standard

at that point just encode this onto some NFC chip tbh

you can find 1K/4K ones cheap enough as stickers

then duplicate of the wallet restore (As fallback) without txids

phones can just tap/scan this

hmmm

and there are standards to resolve them as urls automatically

you can even write to them with phones too

but will it be as easy as printing

you can support multiple features Cindy

specially with txids being dynamic

you can always re-scan /write the nfc with more txids

sometimes there are issues with the exact restore height, I believe it is better if you set the restore height some small # of blocks b4

and leave the permanent one with just restore height

indeed nioc

I tend to set it to a week before :')
