Luckily for Dash, our decentralized funding and governance model is so solid, with a high enough marketcap, we could vote to start our own Apple if we wanted.


What does that even mean?

You are all fucking retards spewing idiot dipshit bullshit.
..to make money off your stupid scammy ass "bags"

Well, their gains are measured in BTC aren't they.

Tells you all you need to know  Grin



Why does it matter? Gains are gains.

Otoh was bragging recently about his gains to pay for his lunch/meal.

Did you comment on that as well concerning his gains being denominated in USD?

Question in regards it to a cold wallet, moneroaddress.

When depositing coins to your cold wallet, you can check to see if you received them. You just have to enter the view key, public address, and tx id on xmr.llcoins.

Now, how can I check if there have been any transactions since you've initially deposited them? Verifying that there hasn't been a hack on your wallet>
There is currently no easy way to do this. However, in the future there might:

https://www.reddit.com/r/Monero/comments/51i0n7/solved_it_hopefully_heres_how_we_can_make_the/
What would be the best currently available (though not easy) way to do this?
First, you'd have to fully sync the blockchain on an online computer. Second, copy simplewallet, bitmonerod, and the blockchain to an USB and plug that into the offline computer. Third, use bitmonerod in offline modus (--offline flag) and it should use the blockchain you have already synced on the online computer. Fourth, use --restore-deterministic-wallet to create a wallet with your seed offline. Lastly, use refresh to sync your wallet. It will refresh up to the last block you have synced online. It should then show all the transactions (both incoming and outgoing) of your offline wallet up to that block.
That's quite an ordeal. I think someone (moneromooo?) was working on a way of getting the key image from a transaction so you can check the spent status using Moneroblocks API... (like Luigi's coin checker)
Note if you are already checking arrival of funds via the checktx page, there's a rather simple way you could generate the key image offline for just the output(s) you care about. This would take only a minute or two and not require syncing the chain or restoring a wallet.

I would need to set up the code to do it though.  Cheesy
That sounds potentially very useful. What information would be required on the offline computer to generate the key images in that simple way without restoring a wallet or syncing the chain?


You can generate the key images with the account keys, tx_public_key, and real_output_index (for each output).

You would have to feed your offline machine this information to allow the generate_key_image_helper function to generate the KIs.

The generate_key_image_helper function has a few steps in the KI creation where it calls the base generate_key_image function below:

Code:
void crypto_ops::generate_key_image(const public_key &pub, const secret_key &sec, key_image &image) {
    ge_p3 point;
    ge_p2 point2;
    assert(sc_check(&sec) == 0);
    hash_to_ec(pub, point);
    ge_scalarmult(&point2, &sec, &point);
    ge_tobytes(&image, &point2);
  }

generate_key_image_helper code:

Code:
bool generate_key_image_helper(const account_keys& ack, const crypto::public_key& tx_public_key, size_t real_output_index, keypair& in_ephemeral, crypto::key_image& ki)
  {
    crypto::key_derivation recv_derivation = AUTO_VAL_INIT(recv_derivation);
    bool r = crypto::generate_key_derivation(tx_public_key, ack.m_view_secret_key, recv_derivation);
    CHECK_AND_ASSERT_MES(r, false, "key image helper: failed to generate_key_derivation(" << tx_public_key << ", " << ack.m_view_secret_key << ")");

    r = crypto::derive_public_key(recv_derivation, real_output_index, ack.m_account_address.m_spend_public_key, in_ephemeral.pub);
    CHECK_AND_ASSERT_MES(r, false, "key image helper: failed to derive_public_key(" << recv_derivation << ", " << real_output_index <<  ", " << ack.m_account_address.m_spend_public_key << ")");

    crypto::derive_secret_key(recv_derivation, real_output_index, ack.m_spend_secret_key, in_ephemeral.sec);

    crypto::generate_key_image(in_ephemeral.pub, in_ephemeral.sec, ki);
    return true;
  }

Sorry for quoting the code, I needed to post it for myself as a refresher given it's been a bit since I looked at these functions.

i speculate c++ code.  Tongue

Looks like 0.016 is being defended well. Don't see .015 re-entry especially with all the news coming out of everywhere. Ideally the new floor from this whole DNM run should have been 0.02 to give XMR a lot more visibility and welcoming merchants, but this coin has attracted more greedy regulars than any coin I have seen in my time in Bitcointalk.

Like Adam Sandler said "What is wrong with you people"?  Lips sealed

Who exactly are you accusing?  Markets market.  We would rather have that than the opposite.  Greedy regulars are not causing this correction.  >500℅ rise over a few weeks is.

I didn't mean you and it's OK to feel defensive. No one should feel defensive. You know you have contributed a lot to Monero in terms of this thread, so there is nothing to feel guilty about and hey if some moron wants to be taken advantage of, then you should help them, right? I am not sure but I think you have contributed to the development of Monero in terms of contributing to the codebase, helping newcomers, donating to the development, bringing awareness etc etc. You probably have shined the most in terms of helping noobs not lose their money by giving free trading advice, posting charts and telling this thread what needs to be done in terms of trading. I don't know why the entire thread is not saying they are indebted to you forever.

You know XMR didn't have to rise by 500%, if *that* is the reason that there "needs" to be a correction. Plenty of scamcoins didn't have any reason to but with the rise in prices by a disciplined community they were able to attract developers, marketeers and a thriving community while Monero was busy staying in the gutter. At that time no one was here to help the newbies  Cry
 

Monero did need to rise by 500%.  Did it have to do it overnight?  No, it should have done it gradually over the last year or two to be ready on time.  Sometimes when running late, one must go faster in order to catch up.  When going faster, often a breather is required before resuming faster.  Eventually, when going faster, one overshoots the destination.  That's not yet, BTW.
 

  Volume (heart rate?) under 7500.  Seems a fairly deep correction off of 115000.  Ready to start running again?  I know it's not the weekend, but...

edit:

Shorters starting to do their thing again...


Yah "they" will do their thing. Seems like something *you* have never done before  Roll Eyes

Good idea to really have some DASH/Darkcoin on the side till this settles down if only because the number of "they" is a LOT less than this pile of gold here that need not be missed.

I am surprised that the entirety of DNM hasn't decided to get rid of Monero just yet, but will not be surprised if it happens.

Why would they get rid of Monero? They just started accepting it.

I'm a bit afraid that the dev team made their cash and are not so much in business to develope the GUI.

I mean i could do this with java in 2 days. I dont unterstand whats their problem here...they have had now 2 years.


Lol epic!!

What movie is this from?

I speculate that monero goes sideways.

Given the world is on the cusp of a financial recession (in my opinion), monero, btc, and precious metals will be a safe haven.

Lots of developments for XMR and with the current stewards of the project I am confident in the direction the project is going in.

GUI or not...

Will you make a thread in the future if and when you make a call and it is wrong?

Smoothie dropping some more nice coins on us. I am really impressed with the holograms on these and am curious how the laser work will turn out on them.

Huli pau!

Thanks Blazed.

What I am aiming for is a sparkle effect. That is a very fine balance between keeping the characters clearly visible but also not burning through the hologram.

I think i've found the sweet spot in the settings. Probably I will do a few tests just on the holograms that are not on any coins.

Where are the first bits?

Sorry I must have misread your question. The first bits will likely be lasered on to the upper left part of the hologram along with the serial #.
890  Economy / Auctions / Re: ❎ LEALANA - "Sailing Into Uncharted Waters" AUCTION #1 ⭕️ on: September 14, 2016, 07:18:43 AM
Where are the first bits?

It is completely random. The coins have not been given addresses yet.

It of course starts with a '1'.

is there a kama aina rate for these coins?  Cheesy

Maybe, if you are Kama'aina.  Wink

Sharp looking coin Smoothie, great work. Reminds me of some of the old school Royal Hawaiian Mint coins done by Norfeds BVNH. Which isn't a bad thing ! Cracking holo, a real step forward IMO

Mintage question .... Is it 250 total across both finishes, or 250 for both of the finishes making 500 total ?



250 for each
893  Economy / Collectibles / Re: ❎ LEALANA - "Sailing Into Uncharted Waters" - KING KAMEHAMEHA I ⭕️ on: September 13, 2016, 06:15:42 PM
I agree they do look awesome.

Seen these are kinda limited edition will they come with certificates, boxes, etc?

Not that I won't be interested without, just curious Wink

Certificates and capsules for sure.

I've been looking around for boxes that fit these and haven't had much luck. There is a site I found that will custom fit your coins in a wooden exterior box.

Probably will include it as an option for those who want it at an added cost. Currently I do not know the cost yet.

It's been crazy just to get these coins out to be posted yesterday.

More info to come...

that's a freaking awesome hologram

was going to say the same. Would love to see a gif or short vid of the hologram at different angles.

Definitely something I could post. Thanks for the suggestion.

Yeah this is a beautiful coin, but I think I'm most impressed by that holo. Amazing work   Shocked

Curious why you snuck a Monero logo into a Bitcoin denomination coin tho?

Symbolism

Monero is going dark in its technological advancements and it is "setting" like the sun does on the horizon.

Can we reserve a set # now??

If so, can I get set #6 Huh

Thanks

Miner, I will post about this in the coming days. Sorry, so many details and not enough time.
897  Economy / Collectibles / Re: ❎ LEALANA - "Sailing Into Uncharted Waters" - KING KAMEHAMEHA I ⭕️ on: September 13, 2016, 12:22:32 PM
If they can be bough unfunded I'd reserve set #7

Can't see anywhere 1 BTC denomination maybe it's on the holo?

It is on the back of the coin. Upper right side (right outside of the hologram) says "LEALANA ONE BITCOIN".
898  Economy / Auctions / Re: ❎ LEALANA - "Sailing Into Uncharted Waters" AUCTION #1 ⭕️ on: September 13, 2016, 12:19:36 PM
Okay, I read the post in its entirety, twice before bidding, and I did not catch that.

I feel that these should have been sold as sets ( #1 and #1 ), but that is obviously not my choice to make.

I am sorry, but I invalidate my bids. This was confusing.

Apologies, smoothie. I am not one to do such a thing, but I feel that the difference between the auctions were the numbers, and not totally different finishes. I do not wish to fight for a set of these over 2 different auctions.

Thanks

As i can see, one for the Reverse proof-like and one for the proof-like

smoothie, you appear to have 2 auctions for the same coin numbers..

Not a problem.  Smiley
899  Economy / Auctions / Re: ❎ LEALANA - "Sailing Into Uncharted Waters" AUCTION #1 ⭕️ on: September 13, 2016, 12:18:49 PM
Can this be bought unfunded?

Doesn't look like it says 1 BTC on the coin itself.

Just to know.

#3 - 0.26 BTC

Yes you can buy it unfunded, but the coin will be marked as such. I haven't decided how that will look just yet but I will make that clear in the next few days.

The denomination is on the back it says "LEALANA ONE BITCOIN".
