WARNING americanpegasus and other XMR shrills. I have helped you by sending Ethereum's downfall into Monero investment thus raising your price by 50% overnight.

If you start shrilling the forum again, I will attack Monero's weaknesses.

Please stop this nonsense!

Can't we have a sane forum based in factual discussion!

smooth and fluffypony please talk to your supporters and ask them to stop ruining the reputation of Monero with this shit. Readers are tired of the shrills.

I would like to go quiet. Please let me go peacefully.

Frankly, I am kind of annoyed by these kind of threads as well. Guys, let's stick to the regular threads and stop opening new threads. It's just counterproductive.

/research-lab/ isn't the main Monero repo.

If ShadowTrash refuses to pay Shen for his work, I'll cover the bounty myself.

It's unforgivable SDC would advertise rewards for bug hunters, then renege.
So it hasnt been patched yet?! And you guys think its a good idea to attack another crypto?! Also the bounty is being paid you moron (from what I read in slack).

Patched how? Like I stated earlier, that is a testing branch which has not been merged nor implemented yet to the main/master branch of Monero. That branch is specifically meant for testing currently. Any bugs there won't influence Monero currently.

So shen was working on a Monero bug a week ago:
https://github.com/ShenNoether/RingCT/commit/6640e808018bb47ea34fd112dbf2d2bef9c1156b

Which got pulled into Monero 6 days ago:
https://github.com/monero-project/research-lab/commit/b215a98a749c452c0a0336ab4ee93b1d71df2e78

Then he decided to take the crosshairs to SDC and you guys started this PR blast? Why didn't you scream your bug from the rooftop? I'm not saying you guys used SDC as a diversion from your own fucked up code... but I think you guys used SDC as a diversion for your own fucked up code.

Also I tried to be nice but iCEBREAKER you are a little bitch that likes to kick people while they are down and everyone who posted above can eat a dick. And thanks for the money on your uptrend! I was the one buying 500 chunks and dumping them on your peaks!

First and foremost, that code hasn't been implemented yet into the main chain of Monero. Shen specifically asked for testers of the code a few weeks ago so community members could report bugs etc.. Second, this thread was started by a community member, not by a Monero Research Lab member nor a core-team member. Core-team members can't stop community members from opening threads. Also, the reddit posts were mine and I don't have an official "role" as well.

Congratulations on the trading profits.

Good post LiteBit, but I'll take issue on one point:

  • Shadow's ring signature cryptography protected only the sender's identity and that now appears to be broken. Dual-stealth addresses protect the receiver's identity and that cryptography is not broken.

Agree that stealth addresses are not broken. Disagree that ring signatures protect only the sender's identity. They also serve (together with stealth) to resist blockchain analysis, so breaking them makes the overall chain easier to analyze and potentially hurts everyone's privacy.

But as you say the bug can be fixed and the feature hasn't been used that much in the past anyway.



+1, although I have one thing to add:

"ShadowCash is mathematically broken. I urge all SDC supporters to join Monero."

That thread was made by a community member, not an official core-team member or Monero Research Lab member. It's an opensource project, the core-team can't stop community members from posting it unfortunately.

Looks like the "hypothetical scenario" talked about re. ring sigs is now a real one.

So much for the much heralded "bullet proof" approach to privacy. The whole shadowcash chain instantly de-anonymised with a can-opener.

Of course this doesn't apply to Monero because they understand their "math" and shadowcash didn't.

This does not apply to Monero!

Indeed. Just like sinking didn't apply to the Titanic  Wink

Shnoe = Shen Noether, who is a member of the Monero Research Lab. If you actually read that blogpost you would understand why it doesn't apply to Monero.

Maybe people are starting to look at "altcoins" such as Monero because Bitcoin is showing its age.  
Fine with me!

I bought Litecoin with profits from Bitcoin. I bought Monero with the profits from Litecoin. Not sure what I'll do once we pass 0.002600 Wink

Hodl like a true mustang of course!

This is the wrong thread for this but I know someone here can help me.

I have an old Monero wallet that I haven't touched for 1.5 years. I'm not sure how much I have in it and wanted to check after todays price increase. I downloaded the Monero files and the blockchain. Put the blockchain and my old key file in the same folder as the bitmonero.exe file and simplewallet. When I run them both the wallet won't update because it says the deamon is busy. Has been like this for several hours now. Anyone know how to fix this?

Are you fully synced? Use "diff" in bitmonerod.exe (the daemon) to check your blockheight and compare that to http://moneroblocks.info/.

Try downloading the Monero files and syncing the blockchain from scratch. After that, place your wallet files in the same directory as simplewallet. If you created the wallet on the same OS, it should update itself.

Alternatively, one can import the blockchain using the method described here:

https://github.com/monero-project/bitmonero/releases/tag/v0.9.0

Make sure to grab the binaries of 0.9.1 though:

https://github.com/monero-project/bitmonero/releases/tag/v0.9.1

Syncing from scratch is more convenient in my opinion and probably faster as well.

Anyone knows where the 130-160 shorts (x3) get margin called?

I already replied in another thread with a rough approximate. To calculate it exactly one needs to apply the following formula:

(amount of collateral - (amount of units/shares * price)) / (amount of units/shares * price) = % of maintenance margin

Amount of collateral is the sum of what is sitting in the account already + the proceeds from the short shale.

Thanks for the info dEBRUYNE. Had no idea about it and -indeed- solved a lot of questions...

That formula is for shorts by the way. Formula for margin longs is:

((amount of units/shares * price) - amount of additional money borrowed) / (amount of units/shares * price) = % of maintenance margin

An example of amount of additional money borrowed would be as follows:

Let's say an investor buys 10k$ worth of shares and loans an additional 10k$ to buy additional shares, then the amount of additional money borrowed is $10k.
2032  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: February 13, 2016, 03:34:07 PM
Looks like there have been liquadated some shorts now. I've seen some repayments of loans recently.
That might be a good shorting opportunity if not that many are not holding a short position + the price has exploded.

My own positions are in lending markets so my views are biased to that direction.  Grin I love passive income and compounding interest which I have been able to collect recently.

Lending rates are still quite high, so probably still a lot of shorts are either taken out or outstanding.

So the 25-35 zone is fireworks probably.

IMO if this breaks 35 no one should be short anyway...

Probably earlier I think, if you use the 33% you get around 200-220k.

Not sure what the bounty is, but if the devs confirm the bug then the bounty should be paid out.

You wouldn't be able to move on to zerocash with this hanging over you. The trusted set-up of zcash is already complicated.

I have been watching / waiting for zerocash to produce something for several years and it seems that their new go-live timing would suit the SDC market launch from Alpha to beta, to production. Good competition for OpenBazaar too.

This is what SWOT is all about. Weaknesses (TBC) can become strengths; threats can become opportunities.

1500$.

binaryFate made this excellent post on reddit a few days ago to explain how ring signatures in Monero work (and a comparison against Bitcoin):

Quote
Here is a short recap, first how Bitcoin works and then the difference when you have ring signatures.

  • "Classic" signing as in Bitcoin: Whenever you want to spend an input (required when you build a transaction), you reference that input and produce a signature with the private key that corresponds to the address to which that input was sent.
  • Ring signing as in Monero: Whenever you want to spend an input, you reference that input PLUS some others with the same amount. Those additional inputs can be anywhere in the blockchain, recent or old. They can belong to dead people or their corresponding private key can be lost (just to underline they are not going to do anything active with you). Once you have this list of inputs (yours + the additionals), you create a ring signature using a private key. To any observer, this signature could have been created by any of the keys corresponding to the inputs. They have no way to know who the signer is, and therefore which input is actually spent in the list and which ones are "the additionals".

To insist that the process is entirely passive for others: they don't need to do anything, they can't even choose who will use their inputs as part of a ring or not. You can be the only user of Monero for an entire week and still create ring signatures as usual. You can also create ring signatures and therefore transactions on an airgap computer without any internet connection. (That should make it clear to you nobody else is involved in the process).

That's difficult to say, depends on the amount of collataral as well. However, normally a ~33% move in the opposite direction of the base price should result in a margin call.

EDIT: Exact formula for anyone interested. To calculate it exactly one needs to apply the following formula:

(amount of collateral - (amount of units/shares * price)) / (amount of units/shares * price) = % of maintenance margin

Amount of collateral is the sum of what is sitting in the account already + the proceeds from the short shale.

And... XMR 20K is broken. Enjoy the ride  Cheesy

Edit: TBH, I didn't expect 100000XMR to be dumped instantly (through static walls on 20000). The first 50000 were bought anyway. Someone wants desperately out, or, wants cheaper coins. The volume on Polo though still is on the rise. Let's have some popcorn. Smiley

There is that one big wall eager to sell, currently ~20k left and sitting at 195k. After that the asks are pretty thin.
