[XMR] Monero - A secure, private, untraceable cryptocurrency

[smooth]

No there is one signature for each input and the key images are not included in the outputs

In this case (key images are not included in the outputs), how do you want to prevent DOUBLE spend ?

whitepaper LNK

LNK: The verifer checks if "keyImage" has been used in past signatures (these values are stored in the set ).
Multiple uses imply that two signatures were produced under the same secret key.

I will sign again and again same input.

Because I made an error (omission). The key images are indeed not included with the outputs, they are included with the inputs.

Corrected:
{

  prefix= {
     input(a1(5 XMR),f1(5 XMR),f2(5 XMR),f3(5 XMR),keyimage(priv(a1)))
     output(r1(3 XMR),c1(1 XMR)) ; fee 1 XMR
  }
  sign(tx_prefix,pub(a1),pub(f1),pub(f2),pub(f3),keyimage(priv(a1)))
}

Different version with two inputs:

tx{
  prefix= {
     input(a1(5 XMR),f1(5 XMR),f2(5 XMR),f3(5 XMR),keyimage(priv(a1)))
     input(a2(4 XMR),f4(4 XMR),f5(4 XMR),f6(4 XMR),keyimage(priv(a2)))
     output(r1(3 XMR),c1(5 XMR)) ; fee 1 XMR
  }
  sign(tx_prefix,pub(a1),pub(f1),pub(f2),pub(f3),keyimage(priv(a1)))
  sign(tx_prefix,pub(a2),pub(f4),pub(f5),pub(f6),keyimage(priv(a2)))
}

Can I use foreign unspent output or this public keys are not known ?

Yes you can use unspent outputs. There is no unspent hash format in the blockchain the way there is for bitcoin.

I found the inclusion of CZ to be bizarre

I don't see why the Czech Republic shouldn't get a voice.

[aminorex]

its already fairy accepted.

not that there's anything wrong with that.

@fluffy, awesome intro on the openalias project.

Can you please check if I've configured an XMR alias correctly at the following DNS location:
myagui.monujo.com

It's not a secured domain or anything at this time, I just wanted to check if I got the implementation basics right.
Thanks!

Might be good for someone to compare XMR price development over the two days to other altcoins. Might well be that the effect of FUD is not even existent...

Quick scan: Over that period the range of LTC was 2.5%,  XMR 13.6%, BBR 27.4%, XCN 34.5%, and all are within 10% of the range closest to their lows over the period.

What I see is that PoW non-app coins (pure currencies) generally, whether CN or BTC based, have declined in degree best indicated by their market cap.

My intuition:  There is no FUD effect.  It is pure imagination.  The price is down because bitcoin.  

My conjecture is that hot money is flowing out of bitcoin into US stocks (BABA) and GBP bets.  This is ADHD money we're talking about.  I give it a week or so, before btc bottoms.  Unless there is an exogenous jump it would be reasonable to expect continuing XMR\BTC decay.  Yet I am unwilling to sell for a turn-around, simply because the scale and likelihood of a positive shock is too large.  The market cap is too small.  One buyer can double the price forever in 20 seconds or less.  I can't risk that.

Looks, it is good. :-) Thank you for your time. I must absorb new information.

There is also a conjecture I've heard that Ethereum is dumping a lot. Why they would be in such a hurry to sell I have no idea. Maybe they got a bill from their lawyer.

I think Ethereum story is more credible. The money which can flow out of BTC is too small compared to the one in stock market/foreign exchanges.

Another one is China money (and I suppose some non-China money) flowing out to speculate on the Alibaba IPO.

EDIT: Oops, didn't see that was already mentioned a few quoted levels back.

You are using opposite logic.  It leads to bizarro results.  GBP and BABA are enormous.  They are sucking the air out of every room, no matter how tiny it is.
Yes, the money flowing from crypto into legacy is tiny compared to the size of the BABA IPO.  That fact is not in any way relevant to the conclusion you are drawing.

An example of a reasonable inference:  BTC is tiny. Therefore the money flowing out of BTC into BABA will not significantly impact the price of BABA.

I'm not above trading BTC comparably aggressive (after all, some of those profits then go into anon coins like XMR), but agreed on what you write here: Unless you trade rather small amounts (and can get in and out without slippage, and are nimble enough to jump back in on short notice), it makes little sense to trade the current swings that are largely secondary effects to XMR's older brother Bitcoin. Small correction maybe: It does make sense if you aren't attached to your XMR position, as in: if you're skimming off profits in USD only. If your goal is increasing an already non-trivial XMR stash, I find it hard to believe this can be achieved by swing trading, given the current market conditions.

I'm glad the dev team is still so dedicated.
Hope you have better donating system before scum starts to attack Monero again (which I hope won't hapen or won't succeed).

Ethereum is cashing out. They announce it in advance and the last round of cashing out is now.

A miner here.

Currently I use Claymore's miner with AMD cards.  I pay a 5% dev fee, which I think is a bit too high, but I acknowledge that the dev deserves something for his/her efforts.

If XMR devs were to create an equivalent or better Windows64 AMD miner with a 4% fee going to the XMR devs I reckon that would be a win/win.


Something to think about.

Big +1

Claymore's is the best available, but comparitively speaking, 5% is highway robbery and he knows it. But when you have no other suitable alternatives, you pay. I would MUCH rather that percentage went to the devs...
