1  Economy / Service Discussion / Bitmain now requiring KYC documentation to buy hardware on: August 23, 2018, 06:54:23 PM
Anyone know the reasoning behind this?  Buying and selling hardware is hardly the same as what an exchange does.  I'm leery about giving them a copy of my passport.
2  Alternate cryptocurrencies / Altcoin Discussion / XMR GUI v 0.12.0 before the fork on April 6th? on: March 29, 2018, 05:08:37 PM
I tried looking for this so if this is mentioned elsewhere please link it and I apologize for posting, but...

Does anyone know if there will be an upgraded GUI wallet release prior to the fork?  I see the CLI version is up already but I can find no mention anywhere of a GUI version update.
3  Bitcoin / Mining support / S9 issue - after reboot it mines but the GUI isn't running on: November 27, 2017, 09:33:17 PM
I seem to recall seeing someone with this issue before but I couldn't find it.  Do any of the linux peeps out there know off hand how I can try and run the web GUI from SSH?  I am able to SSH in just fine.  I think if I can get the GUI up I can probably just reflash the firmware and fix it.  I want to avoid use of the reset button if possible, especially since it is clearly mining just fine.
4  Bitcoin / Hardware / Blackened power connectors on: September 11, 2017, 04:05:09 PM
I posted about this some months back in the S9 thread but didn't get much in the way of comments.  I am wondering when I should be concerned about this and what, if anything, I can do about it.  It has definitely gotten progressively worse.  This is one of the autotune S9's (13.5 Th) and it is only happening on two of the boards, so clearly the two drawing the most power (it tunes to 653, 653, 572 freq on the three boards).  Since it is an autotune miner there is no way to downclock it or I would.  I am using an EVGA 1600.  The connectors are definitely hot to the touch.  Weather they are hotter now than they used to be I can't say.  The miner has been running for like 9 months or so.  I'm kind of to the point that I don't want to just wait for the fire and would like to find a solution before that happens.




5  Alternate cryptocurrencies / Speculation (Altcoins) / [Speculation] Poloniex problems related to alphabay on: July 15, 2017, 12:06:10 AM
Pure speculation on my part which is why I put it in the title of the thread but it makes sense.  If "the man" has forced polo to freeze certain wallets belonging to alphabay admins (or vendors for that matter) then that could well mean that many, many, user wallets get frozen right along with it.  It could also mean polo has temporary insolvency issues because their own hot wallet totals might be locked up.  You can be sure that if the government came along and gave orders to freeze certain things they would also be giving court orders not to talk about it at all.

The ZEC wallet is completely down on polo and the explanation makes no sense but I believe I heard that alphabay had recently enabled ZEC on their market (I may be wrong on this so if someone knows first hand please correct me).

It would help explain why polo is such a clusterfuck at the moment and why they don't seem to be able to handle the serious damage to their own reputation that this clusterfuck is causing them.  If they have a gag order and they have multiple cryptowallets that they can't use due to court orders, they may well be muddling the best they can with what they are allowed to still use and can't talk about it openly at the same time.

If they can't touch certain wallets they can still see blockchain transactions which would allow them to still credit accounts for deposit but it would be a more or less manual process. If they are prevented from using some of their main wallets they would also have to figure out how to move coins around in a way to handle withdrawals which would help explain the endless issues there.  Basically temporary insolvency.

6  Alternate cryptocurrencies / Mining (Altcoins) / New X11 asic hardware - PinIdea & Baikal both - just not for you! on: July 04, 2017, 05:29:29 PM
So PinIdea has a new device.  The DRx at supposedly 1200 Mh/s with 4 boards.  There are several listed on aliexpress: https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20170704091749&SearchText=pinidea+drx

It seems to be real based on this github post for the software: https://github.com/stellawxo/X11-Miner/releases/tag/DRX.170414

That is the same person who posted the releases for previous PinIdea miners.

Then Baikal apparently has a new "supergiant" at 2000 Mh/s.  There was already a thread on it that I missed so I'll just post the link to that instead of rehashing it: https://bitcointalk.org/index.php?topic=1989029.0

Both PinIdea and Baikal have websites and yet neither of them have listed these latest devices for sale on their websites.  
7  Alternate cryptocurrencies / Mining (Altcoins) / PinIdea.io x11 asics on: January 18, 2017, 07:24:24 PM
I may be jumping the gun on this but I am making this post for two reasons: one, I have seen enough of these situations to recognize that it looks like I was ripped off, and two, because I wish I had found a post like this before I ordered a miner from this place.  I sincerely hope I will have to come edit this to say that they came through and I was premature to worry about it and I got my miner and it rocks and all is well.  Sadly I fear that in reality I will eventually have to edit out the word "possible" from the thread title instead.

These guys manufactured and delivered x11 asics in the recent past but as with so many companies in the cryptospace it appears they may have gone into full scam mode.  They have a website operating and taking payments through coinpayments.net but they are not responding to my emails.  My order has been marked as "on hold" on their website since I made it.  Coinpayments.net basically just says you are on your own with the merchant so they won't help.  I emailed both pinidea.io's listed support address and a gmail address I found for a Tomasen Shen who is listed on the website as a founder of the company.  None of my emails have been answered.

It doesn't look encouraging that the pinidea.io website lists only 3 people associated with the company but Tomasen Shen's linked-in page (which lists his name as Shen Sheng) doesn't list pinidea.io at all.  Instead it lists "PinIdea Co., Ltd." with the same logo but a website of pinidea.com, a website which does not exist.  It also says "PinIdea Co., Ltd." is a computer game company which employees between 50 and 200 people.  I am inclined to think that is made up since the website doesn't even exist but linked-in says there are 35 employees with linked-in accounts, but it won't show me any of their profiles because they are apparently "out of my network".  And why he has this computer game company listed and not pinidea.io I am not sure but not good signs.

The pinidea.io website also lists another person's linked-in page, a Xinjiang Shao who was also active on dash.org in the past year in threads discussing pinidea.io miner sales.  Xinjiang Shao's linked-in does list his association with pinidea.io but it looks like he has a different full time job so I am not sure what association he has with pinidea.io now.  if I continue to have no response from the other email addresses I may contact him on linked-in next.

I paid just under 50 dash for the miner which came to about $660 at the time of purchase.  I will update this thread with new information.
8  Economy / Computer hardware / SOLD on: November 14, 2016, 06:28:11 PM
I don't have screen shots since I would have to unplug an S9 to plug this back in and take one but this is an early batch S7 with the higher chip count.  I ran it slightly OC'd and it hit a solid 5 Th for the entire time I ran it without excessive HW errors.

I am looking for .3 BTC shipped inside the US.  I would consider shipping worldwide but it is not my first choice and would require the buyer to cover some shipping costs.

Ideally though I would like to trade this for a couple of GPUs.  I would like R9 290's with 4GB of RAM or better.  I realize that depending on the card the GPU's will probably be worth more than the S7 so I can talk about trade plus BTC.  I would want to use escrow both directions, we can each pay for one direction of escrow I guess.  My choice for escrow would be philipma1957 but I am open to other escrow agents as long as they have a supporting rep.

EDIT: SOLD
9  Economy / Computer hardware / [SOLD] S7 B9 4.73th/s - .55 BTC shipped to lower 48 on: July 01, 2016, 12:59:48 PM
Here's the specs on this one:

https://shop.bitmain.com/productDetail.htm?pid=00020151212042549033J27u55CO0610

Not including the PSU.

Not really looking to ship outside the lower 48 but we can talk if you want to pay additional for shipping elsewhere.

I pay shipping but buyer pays for escrow.

It OC's a little and I have been running it this way.





10  Alternate cryptocurrencies / Service Discussion (Altcoins) / Allcoin.com Warning Update - Missing deposits, finally resolved after 2 weeks on: May 08, 2015, 01:34:32 AM

12  Economy / Goods / [WANTED] Low value gawminers gift cards you aren't going to use on: August 29, 2014, 01:28:39 AM
Not looking to pay anything for these but I am hoping to make up the difference between what I can pay for and what something costs on the site.  It's a long shot I know but if you have some credit on a gift card that would otherwise go to waste I would like it.

14  Economy / Service Discussion / Was your exchange account or online wallet hacked? - Possible explanation on: January 08, 2014, 05:32:20 PM
I just want to mention to people a possible exploit that some people may be encountering.  I hear people talk about how their account at this or that exchange was hacked or how their wallet at blockchain.info was hacked.  And some of them say they had 2FA and didnít share passwords between accounts or sites and had complex passwords and such. 

Java is not supposed to be able to interact with other web pages when one page kicks off an applet.  However exploits that let java do exactly that are in no way new.  There is a reason Java has to be updated constantly.  In the past, exploits like this have been used to make your webmail account from another browser tab send malicious links to all of your contacts.

If you are already logged in to an exchange or to an online wallet and you go to a malicious page in another tab that has a java applet that uses a zero day cross domain exploit then that applet could conceivably access all of your other open web pages.  If this happens, the exploit does not need your account info, or 2FA info because you already provided it when you logged in.  All it has to do is initiate transactions through your browser without you seeing them.  Java exploits that escape the java sandbox and interact at the OS level could also do the same thing and have also been discovered repeatedly in javaís long history.

This would also explain why most of these same hack threads also say they canít find any malware after the hack.  Once the browser is closed java is closed too.  No malware would be left to be found.

Food for thought.
15  Economy / Service Discussion / BTC-e removed from bitcoin charts USD on: December 11, 2013, 04:21:14 PM
Why did they remove one of the top 3 exchanges by volume? 

http://bitcoincharts.com/markets/currency/USD.html


Also removed from the euro page.

http://bitcoincharts.com/markets/currency/EUR.html


They still have it on the Roosky money page though.

Just a technical issue or what?
16  Economy / Service Discussion / CampBX Support MIA - Are they stealing customer funds? on: November 21, 2013, 05:24:53 PM
I generated a brand new BTC deposit address at CampBX on Monday night.  I sent 1 BTC to this address without including a fee.  It did not get picked up in a block until about 16 hours later.  At first my CampBX account showed a pending deposit.  By the time the transfer was picked up on the blockchain my CampBX account no longer showed a pending deposit.  The transfer has long since been fully confirmed now though and still my CampBX account shows nothing.  I opened a support ticket on CampBX as soon as I had 6 confirmations and my CampBX account still showed nothing since they say it should be available in my account after 6 confirms.  And the result...nothing.  No response at all.  No activity on my ticket.  Big black hole.

Edited: I had said the transaction was Tuesday night but it was Monday night.

17  Bitcoin / Mining support / Workaround for random miner crashes in Windows on: November 10, 2013, 02:42:30 PM
I didn't have my miner app crash on me when I was using GPU mining, it was always the vid driver.  But now that I have some ASICs I see my cgminer randomly crash, often after working just fine for hours.  For my GPU miners I did something similar to what I am going to recommend here except that I had a script which made them shoot me an email and then reboot (since the video driver would almost never allow me to just restart mining without the reboot).  In this case though, ASICs will allow you to just restart the miner.  So to get my miner back up and mining without my intervention I use this method.

I created a batch file that checks if cgminer is running.  If cgminer is running then the script exits, if it is not running it launches it.

Code:
tasklist /FI "IMAGENAME eq cgminer.exe" 2>NUL | find /I /N "cgminer.exe">NUL
if "%ERRORLEVEL%"=="0" GoTo Eof

start cmd.exe /c "C:\<path to launcher>\Launcher.bat"

Launcher.bat is simply the batch file that I use to launch cgminer in the first place.  If you use a different miner and have a similar problem you can just change the executable name in both places of the first line.

I could make a scheduled task to just run this on a regular basis (every 5 minutes or something) but instead I have a scheduled task that runs this only in the event of an application crash event in the event log.  Since the event log only specifies the crashing app in the details, any crashing application will cause this to run which is why it needs to check for cgminer running first in case some other app is what crashed.  Generally though my miners are dedicated and nothing else is happening on the box so an even log event of 1000 in the application log should always be a cgminer crash for me.

Also, depending on how your mining app is crashing and whether or not you have error reporting on you may want to see this: http://stackoverflow.com/questions/4528697/how-to-immediately-terminate-crashed-application
18  Alternate cryptocurrencies / Altcoin Discussion / a billion flavors of altcoin vs a true electronic currency on: June 27, 2013, 05:11:50 PM
I guess I had hoped for more interest in this topic.
https://bitcointalk.org/index.php?topic=242174.0

I had planned to wait and see what was said before really laying it out there but since no-one had anything to say Iíll just lay it out here.  Some form of widely adopted electronic currency is coming, that much is certain.  It has to be something that is suitable for face to face purchases.  You could theoretically get adoption of bitcoin or litecoin for online merchant purchases where the slow confirmation is not a deal killer.  But if you wanted to pay in electronic currency for in store purchases, slow confirmation will not cut it. Which means bitcoin and litecoin will never be the ubiquitous electronic currency of the masses.

And while I am on the subject of the masses, most people donít care about the technical details (even if they could understand them). They just want something simple that works.  And you can be sure that the powers that be will eventually provide that.  You will get a centralized currency controlled by the world bank or some other existing power structure and it will satisfy the needs of the masses and the merchants but mostly it will satisfy the needs of those in power.  In which case everyone will agree that decentralized crypto currencies like bitcoin and litecoin serve no legitimate purpose and only serve the needs of criminals, and then I think everyone can guess what will happen next.

So if we want the universally accepted electronic currency to also include elements like being decentralized and anonymous then we need to create it now before we wind up with UN COIN or WORLD BANK COIN.

So what is required is an electronic currency with transactions that have a very high degree of confidence in less than 2 minutes.  What that means in terms of finding a fast block time that doesnít cause a massive amount of blockchain bloat in the long run and a lot of orphans in the short run, I donít know.  But you can be sure that confirmations that take more time than that are just too long to be useful.  If I am travelling and I wake up in Thailand and want to pay for breakfast before catching a plane to Japan where I want to pay for dinner, then I need an electronic currency that allows me to pay at the register, which means it needs very fast confirmations.

My personal opinion is also that SHA-256 is the best choice as an encryption algorithm based on the fact that bitcoin is already responsible for widely disseminating ASIC gear based on that hashing algorithm.  Every algorithm is potentially open to having ASICís built to work on it.  If a new coin based on scrypt (or anything else for that matter) really takes off, it is not clear that some kind of ASIC gear monopoly would not develop around it.  It is a good bet that an ASIC monopoly on a new SHA-256 based currency would not happen.

So thatís basically my spiel.  Either we can watch a decentralized currency that meets the needs of the real world arise to become the electronic currency of the planet, or we can wait and inherit a centralized electronic currency from someone like the world bank.

I have also watched a remarkable number of altcoin launches in a remarkably short time here so I know a lot of people are probably going to roll their eyes at the suggestion of yet another coin.  However I think that if done correctly, with lots of advanced notice, no premine, multiple pools setup at launch and so on, then it could start with a huge advantage and a much better chance of becoming the universal coin that I believe is coming one way or another.
19  Alternate cryptocurrencies / Altcoin Discussion / Community Coin - just an idea on: June 24, 2013, 06:01:10 PM
I think most of us can agree that there is a glut of altcoins.  But I suspect that most of the people who frequent this part of the forums can also see that bitcoin itself does not have what it takes to really deliver on the promise of what an electronic currency needs to be.  Both bitcoin and litecoin strongly benefit from being the first of their kind despite their drawbacks.

However, some form of electronic currency is, I believe, inevitable.  Something resembling all of these cryptocoins will eventually arise as a truly global electronic currency.  The problem as I see it now is that this altcoin bloat dilutes the field.  Maybe the coin which will gain widespread adoption exists now, but maybe not.

Imagine being able to log into the website for your fiat currency bank and with a few click sending a payment in cryptocoins to anyone in the world with no currency conversion fees, no taxes, no fees at all other than those imposed by the bank itself (which theoretically you could avoid or reduce by switching banks).
   
I know you are probably thinking that you can already do a version of this with bitcoin and other altcoins and why get the bank involved at all.  The answer is that real widespread adoption will not happen unless something like this happens.  Our grandparents, indeed for some of us even our parents, will never use any cryptocoins the way they are now.  It is true that in some respects the infrastructure for ease of use does not exist and that can be remedied to some extent with new crypto coin start-ups.  But the cryptocoin that really gets used as a currency the world over, the one that really gains widespread adoption, has to be easy for the noobs.

In order to be useful for a currency, confirmations have to happen faster than they do for bitcoin.  This I think, goes without saying, but you will never see the sort of ubiquitious adoption of bitcoin as an electronic currency that I am talking about for that reason alone.  And because the world needs some kind of universal electronic currency, there absolutely will eventually be one form that does get the kind of widespread adoption I am talking about. 


Community Coin

With these issues in mind I thought it might be worth creating a coin that the community actually wanted BEFORE it was even released.  Some of the issues that would need to be sorted are block sizes, block times, confirmations, difficulty retargets, hashing algorithm, etc.  If these factors are determined in advance in a way that the community agrees makes the coin look like a potential candidate to be a real contender as a worldwide electronic currency then the hype will exist before the coin.  This should remove the need for a dev premine (to support the coin with giveaways, faucets and whatever else, blah, blah, blah) because theoretically the coin is already popular before it is released based on the fact that the community discussed it and helped create it to begin with.

If it was done right I could see a release that already included multiple pools for people to mine on, promises from cryptsy or other exchanges for early inclusion, and so forth.  The idea being that the interest in the coin exists to such a level before it is released that the release is basically guaranteed to see widespread support.

I am not capable of creating an altcoin so this is not me offering everyone a chance to help me make ďmyĒ altcoin.  This is just an idea I wanted to float to address a problem I perceive in the proliferation of altcoins.  It also seem possible that after some conversation about the ideal characteristics needed for a coin to gain widespread adoption as an electronic currency an existing coin may be discovered to already have the needed characteristics in which case maybe we can focus community awareness on that and support the coin or coins that have real potential.

20  Economy / Trading Discussion / Is this laundering stolen coins? on: April 28, 2013, 02:25:58 AM
Just curious if anyone has noticed in the blockchain largest transactions list how there is frequently a trail of large transactions going from wallet to wallet happening minutes apart.

http://blockchain.info/largest-recent-transactions

If you look you can usually find a series of transactions where the destination wallet from one large transaction is the source wallet in another transaction a short time later and the same coins get transferred over and over again.  Does this look like someone trying to hide or launder stolen coins to anyone else?  I can't think of why anyone would be doing that for a legit purposes.

At the moment I am posting there is this series for example:

http://blockchain.info/tx/118a3b4e337e867c1a5c011a5ffb1ae181521a9281f340658513e661ba58175b
