41  Economy / Computer hardware / Re: [WTS] Hashnest 78TH/39 Units of S4 on: February 18, 2016, 06:48:19 PM
You can't get these shipped anywhere. Its $400 for handling and shipping fees. See the other thread with someone else selling some S4s from hashnest.

I believe he's trying to sell the account, not necessarily have them shipped. If true it might be easier for the buyer to contact Hashnest first about having a new account created so they can simply transfer ownership of the units instead of transferring control of the account.
42  Economy / Computer hardware / Re: [WTB/WTT][Canada] Full/Part GPU rig, GPU rig frame, no PSUs on: February 10, 2016, 06:31:44 PM
I have 2 ASRock H81 Pro BTC motherboards and two open air GPU frames. The frames are stackable. I'm located in the US but these frames are durable, lightweight aluminum. They weigh only a few pounds combined, so shipping should not be overly expensive. If you're interested let me know and I'll send you some pictures when I get home (I'm at work right now   Roll Eyes )

I also have 10 powered risers, 3 that take molex connectors for power and 7 that take SATA.

R3 connects 11 banks to distributed ledger using Ethereum and Microsoft Azure Grin Grin Grin knew this last week  Tongue

They forked Ethereum and will run their own private chain. Its great exposure but I'm not sure it actually helps other than to get minor publicity for the original Ethereum.

Does ETH have a block size issue like Bitcoin?
Does ETH have known scaling hurdles like Bitcoin?
Does ETH have confirmation slowness like Bitcoin?
Does ETH POS have holes that will eventually be its downfall?

So, no answers?

Ethereum does not have a hard coded Block Limit like Bitcoin. Ethereum employs a slightly different system. The number of "contracts" or standard transactions occurring on the Ethereum Blockchain is limited. I remember seeing somewhere that its like 1.20 times the exponential moving average. This effectively means that only so much "gas" can be expended per block which is a limit to the block size, albeit a different kind of limit compared to Bitcoin. In Bitcoin this would be like saying there's no limit to the block size but a block is only allowed to contain a maximum of "X" transactions. Its a different kind of limit.

I'm not exactly sure how this would affect scaling but my guess is that Ethereum will scale more easily than Bitcoin. The amount of "gas" being expended per block will be adjusted upward as blocks become more full, which will make blocks bigger automatically. The only thing I'm not sure about is how they decided on 1.2 times the moving average.

Confirmation times are perfectly fine in Ethereum. Average time is about 12 seconds (in theory), so its significantly faster to confirm compared to Bitcoin. Even if the Ethereum network was operating above capacity, the short block times should allow Ethereum to clear any backlogs significantly faster than Bitcoin does.

As for POS I'm not sure what the long term plans are. I believe they are still working on the POS implementation, but I would expect something fairly innovative since the Etehreum team has a tendency to want to improve on existing tech. Maybe somebody else can provide some information about the impending POS system?
45  Bitcoin / Mining speculation / Re: New Mining Farm on: January 19, 2016, 06:29:21 PM
This is my first topic on this forum , and I am seriously thinking to start a small Bitcoin mining farm , and I have around 30k USD to invest in this venture . Would you consider this investment a good one , considering the current developments in the bitcoin industry as well as the fact that the local power rate in my area is around 0.22 USD/KWh .

I am interested in either the Antminer S7 or the Uranus Miner 6.0 TH/s .

Any tips on how to buy the equipment at a lower price , or cheaper setup alternatives , if any . 

Thanks for your support .

With an electric rate that high I would not consider mining a good investment. That's three times what I pay and probably about double the national average in the US. I think you might be better off spending your money entirely on Bitcoin miners, and then finding a good hosting service to run them for you. Otherwise your electricity costs are going to cut into your profits significantly.

47  Other / Beginners & Help / Re: HELP! Total Newbie was told I needed to accept Bitcoin for charity on: January 14, 2016, 09:57:25 PM
The easiest way would be to simply post a donation address and its qr code on the website.

It looks like OP is trying to scam in the name of charity Sad Utterly disgusting.
He will probably reply posting his Bitcoin address and adding a sob story,
Watch.
Provided that he posts the address on the website, I highly doubt that. This is their website: http://www.silverstatehope.org/home.html and you can look up the name on the IRS site here: https://apps.irs.gov/app/eos/mainSearch.do?mainSearchChoice=pub78&dispatchMethod=selectSearch. The organization is located in Las Vegas Nevada.

Yes it definitely appears to be a valid organisation, although if the OP could post the EIN for their charity we could verify that immediately. According to their facebook page they just recently opened: https://www.facebook.com/Silverstatehopefund

To answer the OP, the simplest thing to do would be to open an account with https://www.coinbase.com/ or https://www.circle.com/en. Both of these websites will provide you with an online Bitcoin wallet. Its not the most secure because you're relying on a third party, but if you're only interested in immediately converting donated BTC to dollars, these websites will be your best friend. Both of them allow you to link a bank account to your Bitcoin wallet. You can convert to USD and withdraw the funds directly to your bank.

In order to integrate it with your website you would only need to post a donation address for BTC somewhere on your webpage. This would be your wallet address provided by Coinbase/Circle depending on which you choose. Any donated money is automatically in your account and ready to be converted/withdrawn. You never need to touch the BTC yourself, and you won't need to integrate any Bitcoin wallets with your website. For what you're asking, I believe this will be the simplest solution for you.
48  Economy / Computer hardware / Re: [WTS][EU] Sfard SF100 Miner (Scrypt and SHA-256 Miner) -very eficient- on: January 14, 2016, 07:33:12 PM
according to my calculation this miner barely makes 0.012 btc a day so it will take 200+ days to just break even. 3.3btc is unrealistic. i think 1.2 is a fair price. anyway the only valuable thing on this miner is scrypt, the rest is just burden.

Anybody buying this will be buying it for scrypt hash power. The sha256 is just extra. But I'm fairly certain you can shut off the sha256 functionality and mine only Scrypt. 51 mh/s @ 220 watts probably makes this the best scrypt miner currently available anywhere in the world, at least in terms of efficiency.

That said 3.3 is still too high. I've got a Gridseed G-Black making about half the power at 26 mh/s and I would consider myself lucky if I got 0.4 BTC for it

I am curious though...how did the OP acquire this miner? I was trying for a long time to buy one in the states and nobody had one to sell.

The US is now blowing up cash reserves Grin

http://www.cnn.com/2016/01/11/politics/us-bombs-millions-isis-currency-supply/index.html

On a serious note how do you guys feel about organisations like ISIS turning to Bitcoin because of things like this? Personally it makes me a little sick but I understand that what Bitcoin provides for all of us makes this sort of thing possible. A necessary evil I suppose.

 
in the near future, there will be no cash so everybody needs bitcoin accounts..

I suppose but I'm talking about right now. I don't think its unreasonable a day after having a pile of cash blown up, for ISIS to be looking at alternative ways to store and transfer money.

I just wonder how everybody else feels if we know that this sort of activity was occurring today on the Bitcoin network. Does it affect your outlook on Bitcoin at all going forward? Believe me if you think regulation sucks now wait and see what happens if regulators believe Bitcoin is significantly aiding terrorism...

added all nodes that i found on forum and blockexplorer, still 0 conections lel

That sounds like a firewall problem, I can't imagine there are no nodes available at all.
52  Alternate cryptocurrencies / Announcements (Altcoins) / Re: PotCoin | GROW WITH US | CRITICAL WALLET UPDATE - POSv | on: January 08, 2016, 04:51:23 PM
how to sync wallet.qt long? I have tried to enter the correct node but still can not sync.

Try using a .conf file instead of adding nodes directly to the console.

First open this folder:  C:\Users\YourUsername\AppData\Roaming\Potcoin

Then create an empty text document and enter as many lines for nodes as you want, with one node per line. They should be in the format:

addnode=www.xxx.yyy.zzz

Here is a short list of some nodes I found in my 30 second search, I have no idea if these are still valid:

addnode=162.243.214.135
addnode=213.95.21.24
addnode=88.198.110.120
addnode=91.121.85.62
addnode=188.226.135.210
addnode=162.243.227.221
addnode=5.255.66.44
addnode=23.253.70.235
addnode=162.243.224.78
addnode=172.245.21.210
addnode=162.242.156.243
addnode=209.141.39.184
addnode=23.253.74.25
addnode=23.21.136.204

When you have all the nodes you want, save the file as potcoin.conf and close it. Then run the Potcoin client, and hopefully you will get synced. No need to do anything with the console.

Simple question and maybe this has been addressed someplace else, but from what I've been reading Ethereum will eventually allow anything to serve as a tradeble currency or "token" within the Ethereum ecosystem. So what is the purpose of the Ethereum currency itself (Eth)?

Say for example I'm a company and I want to issue shares. I want to do it simply with a friction-less system (i.e. instant with minimal fees) that allows me to issue or transfer shares easily, and publicly verify ownership. Based on Ethereum I can simply create shares from nothing and issue them within Ethereum. All the share holders have to do is prove they own an address which contains shares that I've created. Those shares would not exist outside of Ethereum but who cares? The point is just to have a publicly verifiable ledger that shows who owns what in my company. In this scenario I would have no need whatsoever for Eth, but I'm still using Ethereum. How would that work?

Edit - I've been thinking about it and the only thing I can think of is that Eth is what will be used to pay fees to support the entire Ethereum ecosystem. Using my previous example say there are a bunch of companies issuing shares. They have each created a token that is unique for their company. But now somebody wants to transfer some shares, which would require a small fee. Well what do you pay the fee in? tokens? Whose token? I think by providing an underlying base level currency (Eth) the developers will be able to get around this. Which would mean all fees are paid in Eth, but whats actually being transferred could be anything. Am I on the right track here?

How do your regulate the share issue system and protect investors? I think for investors, safety is the most important.

This is the point I was getting at. There is nobody to enforce any rules on how a token can be used, atleast not that I've seen. I think this will be a large avenue for abuse. Sure if I was a legitimate company or any other entity I would want to make sure everything is compliant and I'm not knowingly breaking any laws (I say knowingly because here in the US its incredibly easy to break an obscure law without even realizing) But what if I'm not a legitimate company, or just a bored scammer?

Yup. Eth is the "fuel" to keep the network running. To do operations and pay miners. You can make your own tokens to work within this system, but it all needs to be "fueled" by eth.

PS! Before you expose anything of value to ethereum, even when it's fully up and running, you need to check if it's legally recognized by the relevant authorities. You can't normally just issue shares willy nilly (I understand it probably was just an example, but I thought I'd mention it).

I think Ethereum is exactly the sort of of platform that will allow things like that to happen "willy nilly" (using your term cuz I liked it)

There is no central authority that controls the creation of tokens, currency, digital soap bars, whatever you want right? So I would imagine all sorts of "illegal" things will be taking place on Ethereum. By that I mean people may attempt to circumvent laws, not actually selling illegal items.

Try including an extra "add" at the end of your command and also remove the "=" so it looks like this:

addnode 162.243.214.135 add

Don't ask me why you need the extra "add" at the end I just know it works for some clients. And the "=" is only needed if you're using a .conf file. If you add them directly through the console like you're trying to do, I don't think it needs the "="

unbeatable ?

Titen ? 400 MH @ 1400 watt

... not rally unbeatable ...

Titan: 3'5w/mhs
SF100: 4'3w/mhs
Alcheminer: 9'8w/mhs
A2Mega: 12'8w/mhs

IT is not unbeatable, but not too bad...  Roll Eyes

You cannot buy a new Titan. I'm talking about new hardware being manufactured right now. The SF100 is the most efficient scrypt miner still being produced.

Don't bother, the A3 / A4 are going to blow this thing out of the water *IF* SFARDS ever bothers trying to sell any more.

 The whole "dual miner" concept has always been a very bad one - the SHA256 side gets outdated VERY quickly leaving you with an overpriced, not all that great performance Scrypt miner.

 They MIGHT have a faint prayer of making a competative miner if they move to 14/16nm in the next year or two - THAT miner would have a fairly long time at "current tech" and might stay competative long enough to make up for the SERIOUS HANDICAP of pushing 2 different algorythms on one chip.


54 Mh/s @ 250 watts is unbeatable in the Scrypt market right now. The A4 will be better yes, but that is a long time off. Innosilicon is still seeking investors for the A4. It will be a long time before the average person is able to buy one. The 1.7 Th/s mining bitcoin @ 750 watts is, efficiency wise, on par with the Antminer S5. It will be obsolete in 6-12 months thanks to the S7 and others (Avalon 6, Bitfury, etc) but for now its pretty good.

59  Alternate cryptocurrencies / Announcements (Altcoins) / Re: PotCoin | GROW WITH US | CRITICAL WALLET UPDATE - POSv | on: December 15, 2015, 08:02:22 PM
For me Potcoin is just an interesting project. I believe both crypto currencies and the MJ industry are on the rise, and I was hoping Potcoin could make a positive impact. But if 5 years from now nothing has happened and the people in this thread are the only ones who possess any Potcoin, its not going to be a big deal to me. If you lost some money on Potcoin I'm sorry but its a volatile market and you should have been prepared for a loss. If you lost your life savings on Potcoin then you probably were not a very wise investor to begin with.

Having spoken briefly to somebody (RedRhino I believe) representing Potcoin support I believe things are mostly in a hold pattern at this point in time. I was told that in order to proceed with the software development side of things they need a version of bitcoinj for potcoin (called potcoinj...go figure  Roll Eyes ). Bitcoinj is a code library that provides java functions for Bitcoin clients. I think it can even run as a standalone java based Bitcoin wallet. I got the impression that developing a mobile application for Potcoin is not possible without java support, hence the need for a potcoinj.

Also it was mentioned that once the mobile application is ready they would begin approaching merchants. But that is not going to happen until a mobile application is ready. This makes some sense to me as a merchant would have no way to accept payments in person. It also means that all things Potcoin have ground to a halt until the mobile application is ready to go. And there is no end in sight as far as I'm aware...

Any new news on the Pods?  Was hoping the silence meant chips have been sourced or in the works. Roll Eyes

Basically still no chips available. Although I had heard that it took ~3 months for Bitmain to release BM1384 to Sidehack after the S5 was released. Its been ~3 months since the S7 was released. So who knows maybe when S7 sales slow down they will make BM1385 chips available. I think it helps that Bitmain seems to have legitimate competition from Avalon, Spondoolies, and a few others.
