Im sure this question has been asked but whats going on with the whole Chainalysis and Integra FEC shenanigans?
-
ghost_matrix[m]
Is this seriously going to effect Moneros privacy?
-
ghost_matrix[m]
Kind of concerning to say the least.
-
selsta
What are you concerned about specifically?
-
yanmaani
ghost_matrix[m]: have they provided any evidence yet?
-
yanmaani
because if it's just a press release, odds are it's a total nothingburger
-
selsta
They don’t have any tracing capabilities yet, IRS paid them to develop something.
-
yanmaani
Should write up a FAQ entry. "Is it true that [entity] can trace Monero?"
-
as2333
"should you believe the so called news?"
-
ghost_matrix[m]
Yeah i guess no evidence has been provided as of yet. Just amazing how much money has been channelled to break Moneros privacy.
-
ghost_matrix[m]
Usual suspects with the usual excuses lol
-
ghost_matrix[m]
<as2333 ""should you believe the so calle"> No

Hi all, I was experimenting with adding a password to the 25 word seed, using cli and luigi1111's webpage (which btw has a mismatching sha256 ckecksum).Since it has been a few years since those pages were written, is it still a good idea to add a password to the raw seed? TIA.
-
luigi1111w
hmm I should fix the checksum
-
endor00[m]
Speaking of tracing, I noticed that there are still many pools that post all their payout transactions and amounts in their 'payments' page. That's a goldmine of information for heuristic tracing
-
sech1
3 top pools don't do that
-
endor00[m]
We need to reach out to pool ops and/or the ui designers and tell them to remove all references to tx amount and tx hashes entirely
-
endor00[m]
Top3 don't, but a bunch of the medium-sized ones do
-
endor00[m]
It's still a large source of info
-
endor00[m]
And the caveat is that it's often not just a ui fix, but an api fix too
-
xmrmatterbridge
<rbrunner7> Just realized that when I am solo-mining in my daemon I have almost exactly 1 millionth of the total net hashes. Easy to calculate my chances for a block!
-
Mochi101
endor00[m], Monero can't expect users to keep things private.
-
Mochi101
It's not a viable strategy.
-
endor00[m]
That's not an excuse to be sloppy about it
-
endor00[m]
Besides, we're not talking about all users here, just a handful of pool ops
-
algo_max[m]
<endor00[m] "Speaking of tracing, I noticed t"> Excuse my noobness, but could you explain what someone could do with that information?
-
endor00[m]
It provides useful information to figure out who those outputs belong to
-
endor00[m]
Plus, in some cases there are payouts with a single payee - in which case you know exactly how much is contained in that specific single tx output
-
endor00[m]
So if you receive a tx for that exact amount (including tx fee) and that output shows up as one of the tx inputs, you can be almost certain that that's a real spend
-
endor00[m]
And therefore you can exclude that output as a decoy from other transactions
-
Mochi101
Grains of sand in a desert endor00[m]
-
sech1
I doubt miner payouts are even 1% of current Monero transaction flow
-
Mochi101
How is something like this, a site that doesn't keep track of its users, supposed to convey confidently to the user that the site has paid out then?
monero.win/#/game/7766e9dafcad333f
-
Mochi101
endor00[m], ^^^
-
endor00[m]
Mochi101: still enough to deanonymize some people
-
Mochi101
Without giving up that information.
-
algo_max[m]
If people used sub-addresses (or separate wallets) for mining they should be fine, shouldn't they?
-
endor00[m]
At least there are two outputs in that tx, already 50-50 chance
-
endor00[m]
algo_max: addresses/subaddresses don't matter in this case - if I see an output in a transaction that I know is connected to you, I know it's yours
-
endor00[m]
still, it provides some free info about the potential origin of a transaction and works in the exact opposite direction of ring signatures - the harder we can make their life, the better it is
-
endor00[m]
and this one is a relatively easy fix that would remove a lot of useful metadata for tracing companies
-
endor00[m]
look at it from the perspective of the swiss cheese model
-
Mochi101
Maybe contact the offending pools endor00[m]
-
algo_max[m]
Shouldn't that information be considered public anyway? I mean I wouldn't trust a mining pool, exchange, dark market seller or amazon. They could all be run by malicious operators who sell that info, could get hacked or whatever...? The protocol should still be safe.
-
endor00[m]
Individual miners can always check their own payouts individually
-
endor00[m]
And as an outside observer you have no way to prove that the info listed on the payouts page is truthful anyway, since you're implicitly 'trusting' the info contained on that page
-
endor00[m]
So it does nothing from the point of view of spotting a malicious pool op

I think I could sync ethereum with this setup. But I might need to add some ssd storage
-
Inge-
still wondering if monero synch time couldn't be reduced. Not sure what the limitation is. moneromooo? I'm running on a 3970x so I have plenty of cpu cores to go around. Also running on 3 sriped PCIe gen4 nvme drives ...

Bare minimum for an ethereum node :P

at least I can run a few FF tabs on it

Mochi101

-
charolastra
expensive setup. exit scammed lately? :p
-
artefact
what setting did you use for db syncing? afaik that's the main source of slowness. and having to verify hashes for the last few percent
-
artefact
if you have really good bandwidth it might be faster just to download the whole lmdb from somewhere
-
selsta
network is usually not the bottleneck
-
selsta
Inge-: what OS are you using?
-
moneromooo
More batching might help a fair bit. Like, batching all BP in a 20 block span.
-
moneromooo
Possibly also verifying a random 1/N PoW hashes for small N.
-
selsta
I also still like the idea of using supercop ASM ECC library for initial sync
-
Inge-
selsta: Linux
-
selsta
Inge-: how long does wallet scan from block 0 take with your setup?
-
Inge-
Good q. I can test that.
-
Inge-
hm. I guess you want the monero node locally on this setup then, for that test.
-
moneromooo
The wallet could do with a block queue too. At the moment it's simple get next blocks and parse the ones before. No queue.
-
moneromooo
Also, rw locks for the daemon.

-
selsta
algo_max[m]: do you have enough storage space left?

See github, there's a report and discussion from a couple months ago with this, can't recall exact details.

But it should be harmless since the associated hang got fixed.

You might not have that patch then. Check if you do, and let me know if you do.

It really should not bind to 0.0.0.0...

I think I've seen this twice in monero-wallet-cli now

maybe on different machines

I've also had some cases of an outgoing transfer go from pending to failed - but then tried to re-do it and get "double spend" error - but then it was suddenly sent

@luigi1111 Hi, it seems that the sha256 hash of the current site.zip (at Github and at
xmr.llcoins.net) isn't valid anymore.
-
luigi1111w
thanks for the report
-
luigi1111w
monerouser1144 it matches for me
-
monerouser1144
Hi all, I would like to ask if adding a passphrase to a raw seed (for a paper wallet) is a good idea, or if the calculation method (CN Add, CN Xor or Keccak) is still subject to change?.
-
moneromooo
If it changes, backward would be maintained.
-
moneromooo
And the calc method is point addition (modulo). So trivial to reimplement anyway.
-
monerouser1144
@luigi1111 yes, now it matches for me too
pastebin.com/TfLhPzP5 (I had a mismatch last night, maybe it was my mistake)
-
luigi1111w
those methods will stay up indefinitely. I think the regular wallet supports the CN add (or offset)
-
moneromooo
Oh, I assumed the question was about the wallet. I did not realize there were other ways to mangle a seed.
-
monerouser1144
@luigi1111 the sha256 hash displayed at the bottom of your webpage, when I unzip and run it locally is different (984ad27b3759b09532dc95ad09d59fd8918cfd0bfc51f53e4dd6371eb321b6f7)

Of the various methods for generating seeds (see
coldbit.com/what-types-of-mnemonic-seeds-are-used-in-bitcoin) I understand that the "official" sw (Monero cli & gui and MyMonero) use the "new Electrum" format, adapted for Monero?

Question about creating an offline wallet using the webpages kindly provided by luigi1111 or moneromoo: would you trust the PRNG of Chromium (Ubuntu/Mint/Debian) with Linux kernel v5.x, or would you prefer to create the address with monero-wallet-cli ?

how big is the blockchain? whats a good size for my vm's hdd

iirc, yes

Pruned takes 25GB currently on my VPS.

I started with a clean system and ran "monerod --prune-blockchain --detach" (it took several days to finsh, I think it downloaded 60+GB but only needs ~25GB currently)

I'm still unclear if I still need to invoke monerod with --prune-blockchain after the initial sync, but I add it just to be sure.
