Topic: ⭕️LEALANA BRASS XMR COINS FOR SALE ⭕️ (Read 4967 times)

I've done a lot of business with him over the years off and on ofc like everyone else since 2015 or so... He's always treated me quite well, but I'm guessing because I don't fuck up or cause drama/bs, and I'm also prompt on payments and loading, as I know the faster I get it done, the quicker they ship etc etc.

He has always been a fierce privacy advocate, so I don't fault him for not listing his public addresses or giving info to others about re-sold coins, as if you have done business with him, you've probably read his TOS LOL....

I also always knew he was quite long on XMR even before it was worth a dollar, so kind of expected something, just not those awesome silver 3-coin sets right when XMR mooned lol... 🤷‍♂️

He also made me an awesome rainbow blank .25 on my last order of rainbow nickels and dimes, so no complaints here (and no, no hologram sorry lol )



Lastly, he promised me a copy of the first issue of KIZEKRA comics last year, supposedly due out this year, but my PM's and emails to him have gone unanswered like everyone else nowadays...

Anyhow, that's typical smoothie I think.... He takes off on vacation/holiday or whatever, and lets shit build up then is probably like wtf, how can I possibly reply to all this crap lol?

IDK, I've always been a huge fan of his coins, and remember his weekly auctions he used to run for rolls of lealana dimes when 0.1 btc was like 50 bucks ... Damn I wish I had a time machine!

JMO OFC 🤷‍♂️

Edit - the bars he made are really one of a kind, despite the thing about Max/Kialara - Smoothie went super far on the packaging as well as the rainbow steel plates showing the certs etc... Simply beautiful stuff that nobody is ever going to resell, just like the King Kahemena coins we NEVER see for resale here!

I'm not so sure.  He caught a lot of flack for those bars (while being beautiful) for being basically a copy of Kialara's to the T but with his own design.  He was quite rude about things the entire time, he refuses to help anyone out with past product sale questions ets.  The last time I messaged him after sending him a sizable order he never responded back.  Would it kill him to at least say "sorry we've sold out" or whatever.  Quite frankly I'm done doing any business with him as I don't appreciate the way he treats his customers or perspective customers.  Also lets be honest, while he's made some of the greatest coins and designs there are, some of their aspects have been straight up copied details that Casascius did and Kialara most recently.  I also don't like that he doesn't produce the pub-key list like many vendors do.  If he ever reads this my suggestion would be to treat people better, it's not hard to do man.

Always a day late and a dollar short. I'm sure he's coming back someday with something awesome. Those Monero bars he made last year with the Samurai are awesome. Thanks for the info, I'm going to read through that thread.

He just did boys- read his recent topics - one example- https://bitcointalksearch.org/topic/--5308230

Almost shit my pants. Thought he was back with new stuff. Ive been waiting for years to catch Smoothie with a new project. Then realized its an old post. lol.. lame..

Thank you for doing this owlcatz, and for the clear tutorial!

I think a lot of us - including me - will be secretly relieved.

Ah jeez, thanks for doing the google for me!

Update to come soon(tm).... Thanks again!

Lealana 5 XMR Brass Redemption Experiment:

Today I received the coin I'm going to peel.

I looked up the instructions:


Then realized....

I can't redeem it without:

1. The coins XMR address
2. The view key for the address from the COA.

What this means: (PLEASE correct me if I am wrong)!!! 

1. In my case, I have neither, as I received this from another forum member to help me test it - I am waiting to find if he has this information.
2. Anyone with a slabbed coin or otherwise, and DOES NOT have a paper or digital certificate for the coin #, will not be able to redeem it...  (This is not good as I have seen many coins around the forum that people don't have COA's for, and the last 2 rolls of brass coins I purchased, I was never offered the certs, I had to ask, so hopefully anyone else out there got theirs as well).

.... Update coming soon!!! Thanks!!

I should have one in hand in a week or two that I plan to peel. I don't expect any issues, and will post the outcome. 

That's a good question, I don't believe I've seen one stated to be redeemed and I'm wondering the same.  I don't think you'll have any problem and if you peel one please let us know the outcome. 

Just curious - Has anyone tested redeeming one of these yet? They are getting pretty high in loaded value, so I'm a bit nervous and thinking of peeling one to find out if noone else has yet? Thanks. 

I'm interested, are these still available?

I've read the whole post but it is kinda confusing. Do we fund these coins ourselves before you send them out? (I don't want it to say unfunded). Does it have to be 5 XMR?

Thanks.

Can you pick the SN's contained in a roll or are they randomly selected?

I may also be interested in splitting a roll if someone is on the fence about getting a whole one.

Okay so I went through my code on my end to see if I was overlooking anything that gets fed to cn_fast_hash(...) and found nothing really new that hasn't already been shared with you.

There is a '\n' at the end of the END tag line that gets added into the string that is then hashed. For more clarity I am running this on Ubuntu 14.04.

QUESTION: Just to be clear are you able to run your own version of "check_ring_signature" against the information contained in the digital certificate?

If yes, then is your issue mainly about reproducing the hash with the cn_fast_hash(...) function with the input of the digital certificate text?

The hash of the text is used in checking the signature, so if it were incorrect I would assume the check wouldn't work (as in "check out") on my end nor your end. I'm leaning towards this is not the case on your end.

Will do.  The main problem (which isn't actually major) is that I can't get the hashes to match still.  This doesn't affect whether you can verify the
balance of the coin, but it is a bit annoying and is another check which would be nice to do.  I've tried sha256, keccak, cryptonite with the start and end
tags either included / not included.  Extra newlines.  Saving with Windows newline format, unix newline format.  

So I'm missing something that someone else might catch if I just put it out there as it is.

Another 'problem' is that it's C++ code using Monero libraries and at the moment only compiles on my machine running Ubuntu 16.04, so it will take
a little bit of work to get it to compile on another OS.  I really have very little clue when it comes to compiling with make or other things (or even github).

Will let people know when / if it's up in a usable form.

Please share what you have when you have it, it would definitely make less work for me (hopefully) and help users of the coins and other physical XMR coins.  

owlcatz,

I think there are a couple more steps to verify that the coin is funded.

The steps you have above show that the coin had 5 XMR deposited to it, but it doesn't confirm that they are still there.

In order to confirm they are still there you need to:

1) Check the signature/s.  This confirms that the listed key image matches with the output public key on the digital certificate.
2) Check the spent status of the key image.

If step 1) was successful and step 2) shows that it is unspent, then the funds are still there.

I believe step (2) can be done on some blockchain explorers but step (1) isn't readily available yet without doing some coding yourself.
I've made a little command line thing for myself which verifies the digital certificates, and if I can tidy it up enough I'll get it up on github or something.

The way it works is it creates a signature of a single output and key image.

The idea is that it operates as a degenerate ring signature (only one output is used in creating the "ring signature")

I've ordered some of these coins now, and have been trying to throw together some code to be able to verify the balance of the coin.

I'm not 100% sure about how the signatures are generated and how to check them.  The code I'm using right now is taken from wallet2::import_key_images,
and I basically check using:


In this case the hash_input would be the hash on the digital certificate.

Could you confirm if this is correct, Smoothie?

Looking forward to getting the coins

Could smoothie not just pgp sign each certificate? Anyone that tries to fake one with different info will not be able to sign it with smoothie's key. Unless I misunderstood part of the question.

Hi Smoothie.  Yes I'm talking about funded coins.  It's maybe a silly scenario, but say:

1) I bought a funded coin from you serial number 999.
2) I completely lost the digital certificate because I'm an idiot.  Crud
3) I want to sell the coin (still not opened in any way) to someone else, but have no digital signature
4) I make a new wallet and deposit 5XMR into it.  I make a new digital certificate:


5) Some time after selling the coin I withdraw my funds from my wallet, pissing off the new owner (although the coin hasn't been opened so it hasn't lost funds).


It's maybe a strange scenario.  The coin is never opened and I never see the private spend key.


Edit:  I think you addressed my concerns.  Like I said I was a bit concerned because I thought you need Address, viewkey and spendkey to recover the wallet (I believe monero-wallet-cli asks for all of them), but you technically only need the spendkey, since the seed words are an encoding of spendkey, and the whole wallet can be recovered from the seed words.

This only applies to FUNDED coins. Unfunded coins are marked "UNFUNDED" on their holograms prior to shipping.

Are you asking this to determine if a fake digital certificate generated would lead a buyer to believe a coin was in fact funded when it was not?

If so, then first, the scammer would need to have already gotten access to the private spend key without showing any noticeable marks on the hologram. This is possible as tamper evident holograms are not "tamper proof". This is stated in my terms and conditions for each sale I make.

Yes someone could create a fake digital certificate, but:

1. If they can already gain access to the private spend key in the manner described above, what's the difference, they would not need to create a fake digital certificate.

2. If they can't gain access to the private spend key, then the coin should be funded.

Is this the scenario(s) you are speaking to?

Just so I have a starting point...

Is there any way to verify that a given digital certificate belongs to a given coin?
It looks like with the digital certificate, you can check that the outputs are all unspent,
but not that the outputs actually belong to the coin.

If the hash from the digital certificate appeared on the coin (or something like that, perhaps around the edge) then you would
know for certain that the outputs you are checking can actually be spent using the private key under the hologram.

Maybe I'm missing something?  Would be good to know

I know, but I could create another certificate saying the same serial number, but with different address and transaction details.  If I then showed both digital certificates to someone I was selling the coin to,
how would they be able to tell which one is genuine?

The digital certificate has the coins serial number.

Is there any way to verify that a given digital certificate belongs to a given coin?

I am trying but I need another trustable member from the usa to split a 20 roll with me 50/50. Escrow/Funding and/or shipping all handled by a highly trusted member by the name of minerjones. PM me if interested! 

Thanks!

With 4000 brass coins available, there can only be 200 holders of 1 roll each at maximum!

Do yourself a favor and buy the brass today.

I'd be happy to split a roll 50/50 with you. Smoothie, any way we can pay you separately to ensure the process goes smoothly?

Pretty sure at one point he ruled buyer-funded coins out altogether, so yes, this is a good question.

Edit - if anyone would like to split a roll with me, funded, shoot me a pm. I will pay in xmr, & you can pay me 1/2 in btc or xmr, we can work it out or use escrow if you wish.

thanks! 

I'm still confused because you said "Digital Certificate for each coin similar to below (Only funded coins prior to shipment will receive a digital certificate):"

Never mind, I'm stupid.

 
The only coins smoothie has ever stated would not be sold unfunded are the silver monero coins(25,50,100).  He appears to be structuring these like his previous offerings but with those coins you didn't need a view key to check if they are funded so there was still the possibility of a secondary market.  Without a way to verify the funds no one is going to buy one of these coins on the secondary market.  I'm wondering if that is his intention or he just overlooked it in this case.

View key exists when the coin address is created. That will be given for any and all coins sold.

The digital certificate has the signed message containing the key images that prove the coin is funded.

Can you explain the logic behind this?  How will people get the view key for the buyer funded coins?

Are you funding the coins out of your pocket or do we need to send you XMR first?

When will the auctions go up? and what is the turn around time if we order them?
