[5w00p]

See that which you say is the fallacy.

IT DOES MATTER FOR FUTURE MIXING.

I will try to summon a XMR Dev here to explain.

I am afraid that if your pool does not switch to a mixin of 3 or more with payouts, I will be forced to move to a different pool. I do not say that as a threat, but rather a notice, as I have believed in and used your pool for many months and I wish to stay with it.

But, proper mixin is important to the foundational tenets of Monero, and for pool ops to ignore this is to do XMR a disservice.

[5w00p]

I sent XMR Dev fluffypony a request for explanation.

I realize he is busy, and I don't expect an instant response, and I am capable of finding stuff on my own.

So, I found this from the Monero Missive transcription of Week 2015-02-23:

Riccardo (fluffypony):

"You are spot on…there are two different aspects to privacy in Monero and that is the unlinkability and the untraceability of transactions. Now when we say unlinkability we are talking about the dual-key stealth addressing that addresses that component; but untraceability is another thing entirely. So, the untraceability is dealt with by ring signatures. As MRL 1 pointed out there is a potential compromise, and a cascading compromise, to the ununtraceable nature of CryptoNote transactions.

Just to sort-of explain it quite simply: if I create a bunch of transactions, and in each transaction I have my signature along with your signature…so just by chance I happen to mix with your signature, and it's the same denomination I put every single time. And then in 6 months' time you go and spend that output at a mixin 0. Suddenly what you're effectively doing is you are invalidating all of the times that output was used previously. Which means that all of the transactions where you and I, where I used your signature as a ring signature on it, is suddenly like…well, anybody looking can go "hey, this ring signature is part of an output that was spent, and so therefore the other one must be the correct one." So that revelation becomes dangerous especially when owning a certain number of outputs, and the knowing that you control those outputs leads to a cascade or a snowball.

So what we're really trying to move away from his instead of having "unspent" outputs that we mix with, just having outputs that we mixed with and they should always be unspent; it should be impossible to tell if an output has actually been spent on the blockchain or not.

Now the reason that we might need 0 mix transactions, or mixin 0 transactions, is because traditionally in Monero there is dust. And dust, when you are using it as an input, will never have anything, or will most likely, not have anything it can mix with. So it presented an interesting problem for us and for the rest of the members of the Monero Research Lab. Because not only did we have to devise a scheme that just disallowed mixin 0 transactions, but we also needed to figure out a way to get dust out the system, to maybe do this in a way that dust eventually comes of the system instead of having some sort of magical destroyer of dust go through the blockchain, which is impossible.

So MRL 4 is something that people can read in their own time, but basically the long and the short of it is that we're going to be moving quite soon to a minimum mixin of 2, and we are going to programmatically lock in that within the next 3 to 5 years that minimum mixing is going to move to 4."

Google translation to French:

Vous êtes sur place ... il ya deux aspects différents à la vie privée dans Monero et ce est la intraçabilité et de la non-traçabilité des transactions. Maintenant, quand nous disons intraçabilité nous parlons de la furtivité double clé d'adressage qui traite de cette composante; mais untraceability est tout autre chose. Ainsi, la non-traçabilité est traitée par signatures d'anneau. Comme une LMR a souligné il ya un compromis potentiel, et un compromis en cascade, de la nature des transactions ununtraceable CryptoNote.

Juste pour trier-de l'expliquer tout simplement: si je crée un groupe de transactions, et dans chaque transaction je ai ma signature avec votre signature ... si par hasard il me arrive de mélanger avec votre signature, et ce est la même dénomination je mets à chaque fois. Et puis, dans le temps de 6 mois, vous aller passer cette sortie à un mixin 0. Soudain ce que vous êtes effectivement faire est vous invalider tous les temps que la production a été utilisé précédemment. Ce qui signifie que toutes les transactions où vous et moi, où je ai utilisé votre signature comme une signature de anneau sur elle, est tout à coup comme ... eh bien, ceux qui cherchent peut aller "hey, cette signature de bague fait partie d'une sortie qui a été dépensé, et ainsi donc l'autre doit être la bonne ". Alors que la révélation devient dangereux surtout quand la possession d'un certain nombre de sorties, et sachant que vous contrôlez ces sorties conduit à une cascade ou d'une boule de neige.

Donc, ce que nous essayons vraiment de se éloigner de son lieu d'avoir des sorties «non dépensés» que nous mélanger avec, juste ayant des sorties que nous mélangé avec et ils devraient toujours être dépensés; il devrait être impossible de dire si une sortie a été dépensé sur le blockchain ou non.

Maintenant, la raison pour laquelle nous pourrions avoir besoin 0 opérations de mixage, ou mixins 0 transactions, parce que traditionnellement Monero il ya de la poussière. Et la poussière, lorsque vous l'utilisez comme une entrée, ne aura jamais rien, ou très probablement, ne pas avoir tout ce qu'il peut mélanger avec. Donc, il a présenté un problème intéressant pour nous et pour le reste des membres du Laboratoire de recherche Monero. Parce que non seulement nous ne avons eu à concevoir un système qui vient refusé mixins 0 opérations, mais nous avons aussi besoin de trouver un moyen pour obtenir la poussière du système, à peut-être le faire d'une manière qui la poussière vient finalement du système au lieu d'avoir une sorte de destroyer magique de la poussière passer par le blockchain, ce qui est impossible.

Donc LMR 4 est quelque chose que les gens peuvent lire dans leur propre temps, mais, fondamentalement, le long et le court, ce est que nous allons déplacer assez rapidement à un minimum de deux mixin, et nous allons verrouiller programme dans ce dans les trois à cinq prochaines années que le mélange minimum va passer à 4

Can you guys please change the payout mixin to 3?
Mixin 0 hurts the foundational privacy aspects of Monero. Even if we don't care about privacy of payouts right now, it could matter when the coins are spent in the future.
Being a leading XMR pool, you guys can set the example here by making the mixin 3 or more.
Thanks! Merci!

Mixing for payout from pool is useless.
The mixing is for stealh emitor of transaction.
You know all block find with my pool. 
->
You kow all TX spend or not spend for my pool
Where is interest make mixing 3 , 20 , 50,100 ?
If you can find block with TX speend and find my pool as forged block?
I print all transaction send per my pool
For mixing is not useless . I have need 2 prerequire .
1.) I stealh block find
2.) I slealh Payout
You can make payout to youself with mixing you want before .
Is good pratice for spend coin generated per open pool .
You are ready for mine on blackbox pool?

To put it in a nutshell, mixing from pool is no use because we know for sure that all transactions are coming from the pool.
Mixing is useful once the XMR are on your personal wallet.

Wut. How do we know that?

https://github.com/zone117x/node-cryptonote-pool/blob/master/lib/paymentProcessor.js#L93

Payments aren't processed in the coinbase, they're processed as regular transactions sent to a wallet daemon. It's impossible to tell that they're coming from the pool, especially if you do your bit to promote Monero's transactional privacy by flushing coinbase transactions to a payouts wallet and then processing them from there. If you continue to process them as zero-mixin transactions you'll be forced to make the change once we enforce MRL-0004, so you may as well change now.

Hello is kminer safe to use? my miner has very limit memory and CLaymore crashes a lot. kminer seems work but I fear for safety? thank you.

kminer is not safe.
Have you been on the Claymore GPU thread for the crash problem ?

Ok I get your point but how can we process so many transactions without tons of dust ?
I don't think we'll be able to pay people at low fees and on time if we change the setting right now.
We need to work on it.

I  add mixing 3 in todolist

For information TODO LIST

1.) Solved definitvely timeout miner ( Present , I have find solution need more code and test)
2.) Find solution for user can signed message for defined parameter ( Per ex rles payout , email , other ) ( Fake Auth )
3.) Add graph for many metrics and Publish metric ( I think use sensu for at wit server dedied same for monitoring admin)
4.) Fix Payout definetely with mixing 3
5.) Report bad share
6.) Add many information
..
...
Finished recoded all code pool from scratch
....
..
15.) Sleep and Go playa del carmen for vacancy


For waiting graph on metric efficiency: You can now efficiency pool for 20,50,100,300,1000,5000 Block on page monitoring.

Decided to try a coin. Worked directly on the stock exchange on the Base Address. I understand that all the coins are lost or have the ability to recover? Thank U.

je prend un quote de y'a longtemps mais comment on détermine son : low, normal, hight  ?

You can chose different port to mine at :
3333 for low end hardware
6666 for normal hardware
7777 for killer machine (be careful, if the pool get over 45% of the network, miners from this port may be redirected to smaller pool for network safety)
If you need a HTTP connection, please PM me.

3333 low end hardware : a CPU or GPU
6666 normal hardware : gamer GPU
7777 killer machine : GPU rig (multiple GPU)
8888 : multiple GPU rig
9999 : Chinese farmer

It doesn't change much for the miner (same gain) but if you have multiple GPU rig and use low port 3333, it increases the server charge which is bad so avoid it (we'll see it anyway).

If the server overcharge, we can temporary force everyone on a high port.

I have activate Mixing to 3.

For moment is just for test is possible not multiply fee per x3 .

Multiply fee per 3 is when lower number output .

[5w00p]

 

Great work!

I got paid out and the mixin is 3.

Thank you perl and superresistant for making this change.

[perl]

I have not say is definitely .

For moment is on test .

the problem is bitmonerod make useless dust

http://chainradar.com/xmr/transaction/e195f1f289259a777aaed4e62afafb4415a887bde682b4ad1b6f39788a69498e

Speend : 10 XMR
Payout : 0.7XMR

I catch in TXNO
9.000000000000
0.200000000000
0.300000000000   -> Payout one user
0.400000000000 ->  Payout other user
0.080000000000 -> I have patched code for add dust in change  ( If not make , I increase fee per factor 5 )

Why not spend other TX  ( I have more 20.000 TX not spend )

Present code monero try to spend with lower input  and make more dust without spend old dust .



I have one time per mount spend all TX to my self without refresh for reduce my number of TXNO.
I make more 90XMR for dust per mount
