GPU mining is over, though.  With all the ASIC's coming out, it'll be more or less useless.

Depends to what level, if the thing does say 1000MH/s it's not bad as long as your not paying for electricity, if you were at a company that has a few of them it's even better, OS X I've found is very easy to run a miner on and find it to be stable.

I'm sure will not be worth the price tag, plus firepros have always been quite weak for mining, don't know why particularly.
43  Bitcoin / Mining / Re: NOTICE: WARNING to NEW CUSTOMERS of BUTTERFLY LABS INC (BFL) on: June 08, 2013, 04:10:32 PM
I think there is something about BFL in how they targeted smaller mining operations, encouraging people with 5Ghz units which cost every little where as most other minors seem to target selling very expensive but still powerful devices. I don't believe BFL is a scam but I do think they're just that bit too dodgy to touch unless you like to live dangerously.

Personally I think the market value of bitcoins are getting somewhat unstable right now, better to hold out, there will be newer generations of miner either way, it's just keeping an eye out on which maker to put your money on when the time comes.

I'm not sure why people bought them up in the first place, they cost the same as a half decent graphics card, they hash about as much, but have no real resell value, it's only the fact that they're USB and lower power consumption that they're worth while, for me they're worth nothing as I mine electricity cost free, I liked the idea of being able to just put loads attached to one machine though.

Sorry, sold them on to a user called Projects. Thank you for the offer anyways.
46  Economy / Trading Discussion / Looking to sell BTC for GBP on: June 03, 2013, 07:53:21 AM
Anyone know a good place to sell off some coins quickly?

I used to use XMLGold.eu which wasn't great but was at least quick but they're down till 6th of June.

I need another site or a good safe way to deal with someone directly to secure GBP or even EUROs at a point?

Hey just what I'm looking for.

Can you take something like this:

https://estore.ti.com/BQ500210EVM-689-Evaluation-Module-for-bq500210-Qi-Compliant-Wireless-Power-Transmitter-Manager-P2529.aspx

 http://uk.farnell.com/jsp/search/productdetail.jsp?sku=2146057&CMP=KNC-GUK-FUK-GEN-SKU-G12&mckv=sLhgWcOs1|pcrid|13359103509|kword|bq500210evm-689|match|p|plid

and simplify the board down to being a basic QI charger board that is driven off a USB connection for power and also has an IO pin(s) for driving two LEDs when a induction of the coil is occurring?

Must use Wireless Power Consortium standard components but I'm sure if you follow what this unit has it'd meet that spec.

I'm assuming this isn't all the horrible a job bar understanding some of the spacing/shielding aspects surely it's just simplifying the layout?

Message me if you wish to ask further questions?
48  Bitcoin / Project Development / Re: Asic Miners Available 05/07/2013 on: May 18, 2013, 02:00:25 PM
Hi Everyone,

Let me introduce myself... we have been way under the radar for a while developing our own ASIC miner similar to the avalon Design, it is very unfortunate that avalon have released this documentation as this has prevented us from being 1 step ahead in the development of our ASIC.

Ok moving on to the point as all of you are well aware there are many people out there who are developing pcb's firmware etc to be able to duplicate an ASIC Rig.

We are announcing that we are in the final stages of development with a successful pcb with successful installation of the ASIC Chips....

upon delivery of our ASIC from batch 1 we stripped down the whole machine to its bear materials & we have had the pcb go through thorough simulation.

We are now at this stage 85% there up & running with a 10 chip pcb running 50% asic power we are at this time currently getting ~138mh/s on average per chip...

We have our order for 30,000 Asic Chips ETA for 4/07/2013...

We would however ask all comments to remain on topic for this project & i wish to repeat this is still a "PROJECT" at this time...

we are not offering and products or assembly or pre orders at this time but this may change in the future depending on how this "project" continues as i said earlier the ASIC chips are performing just under 50% of what they are supposed to & we are working on it daily to increase hash rate.

We will update this post when new information becomes available.

Kind Regards
Phil.

How come your not just using the Klondike designs or contributing to them over working on your own PCB? https://github.com/bkkcoins/klondike

I've gotten an idea... Handmade physical bitcoins

Not sure if trolling... or hasn't seen whats already been done before
50  Economy / Services / Re: What business do you guys recommend? on: May 18, 2013, 12:29:36 AM
On a serious note, whats really strong with bitcoin is quite niche tech/online services, I personally don't think there's a lot you can do standard selling wise that beats other credit card accepting companies, such as selling electronics, you'll never beat the likes of Amazon and if anything when your selling those items you don't want the uncertainty of bitcoin to risk your money, producing digital products on the other hand means you can sell a little lower than you want on the expectation that the value will rise and customers will buy on the basis it's a good deal. The other thing is to look at things like Silk Road and go back a few steps from the illegal part, try to find grey areas where the products are perfectly legal but people don't illegal want it on their credit cards or want a no hassle payment.

I have an idea myself for a service to get started but sadly it does require more of my time than I'd like and I can't pay for other developers at best its money spent on graphics work which is harder for me to spend time on.

I'll give away one free idea though, try working on an Android app market that sells via bitcoin, there's a lot of challenges to it but ultimately I'd like to think there's quite a large market from the number of bitcoin apps on the market the next step might be to see if you can get app makers on your store with the idea of selling it cheaper for customers, taking a lower percentage for yourself than Google would which keeps the maker happy then allow the percentage you take to hopefully grow as an investment.

What bitcoin business do you guys recommend me to do?

Sell blood for bitcoins, that's original right?

what no option that he might just slowly give them away once the currency is more main stream?
53  Bitcoin / Development & Technical Discussion / Re: Is bitcoind reliable when depending on it for web services? on: May 16, 2013, 09:52:29 PM
The matchRequest or scanRequest is to scan the block chain. This would be useful if you import a private key or rescan history for a wallet.
You can submit a long list of patterns (addresses) with a single matchRequest, that is more effective, than one by one. The scanRequest is the same but with abloom filter, this would be useful for to scan for an ever larger set of patterns.

The filterRequest is an ongoing subscription to transactions coming in and matching the filter.

Beware that the bloom filter (for scanRequest or filterRequest) is probabilistic so you can get some transactions you do not care, but it reduces the regular transaction feed by magnitudes. The filter also gets updated automatically, so it will e.g. match for transactions spending a transaction that previously matched the filter. You might want to periodically reset the filter on a long standing connection.

The filter is a bitmap in style of a bloom filter at the moment I can only refer to https://github.com/bitsofproof/supernode/blob/master/api/src/main/java/com/bitsofproof/supernode/api/BloomFilter.java
how it is compiled from byte patterns (keys, addresses, outpoints) you want to filter for.

The Java class https://github.com/bitsofproof/supernode/blob/master/api/src/main/java/com/bitsofproof/supernode/api/DefaultAccountManager.java
shows how filter subscription and scanning is used to implement a client side wallet.


Ok, so I think I've got this down, basically the idea should be rather than directly accessing the 'supernode' from a stateless PHP execution I should probably be creating something like a worker service that will subscribe to batches of addresses and then start storing the results of such like when an address has reached a target amount received?

Cheers for all the help, good luck with the full release  Smiley

bitcoinorama is correct, there are other bits n bats to think about, but as far as the boards go
Quote
but if I had chips then I'd send them to you to put them onto your boards, then they would be ready for mining right?

to answer that :-
You will need to sort software, and housing for the boards
You will need to sort heat sink and fans for the boards (ill be looking into supplying them)
You will need to sort a PSU for the boards
You will need a USB lead

but this is similar to how fpga boards arrive....no fan, no case, no psu...and I see these as just an extension of these


It's a shame no one made a kind of medium sized board that would  have wholes for a PCI back plate so you can basically get a load of them and place them in typical ATX case at the same time probably just building in a cheap atom motherboard for managing them probably about as low powered as you'll get without having more unreliable builds anyways
55  Bitcoin / Development & Technical Discussion / Re: Is bitcoind reliable when depending on it for web services? on: May 16, 2013, 02:10:59 PM
Is there by any chance someone where that documents all the possible messages that can be set and expected results etc? Even as a really rough document?

/queue/filterRequest - send a FilterRequest message to get a ongoing feed of Transaction messages on the reply queue that match the Bloom filter, this will keep going until you disconnect

/queue/matchRequest - send an ExactMatchRequest to scan the blockchain for transactions matching the filter, where filter is a list of byte vectors. The byte vectors can be addresses, keys or any data in a transaction script. This scans once starting from an optional time point "after" in the message. Resulting transactions will appear on the reply queue.



Thanks so ideally I'm guessing to monitor any of the addresses I've got to either:

1) do a MatchRequest for each address with my address as the receiving address?

Or

2) do I just create a filterRequest with a filter for my receiving address and I'll essentially get my transactions that way?

if so do you have a rough guess on how long these requests are likely to take?
56  Bitcoin / Hardware / Re: [TENTATIVE] - Avalon PCB Assembly - UK & Europe on: May 16, 2013, 01:40:50 PM
Potentially interested - I'm still researching this and not up to speed on the specifics, but if I had chips then I'd send them to you to put them onto your boards, then they would be ready for mining right? Or would there be something else that needs doing before they are mine-able?
Where are you located by the way? I'm 30 minutes NW of Birmingham.

Well you need a computer to connect the board to I believe unless I'm wrong
57  Bitcoin / Hardware / Re: You can order Avalon ASIC chips here on: May 16, 2013, 11:53:45 AM
Potentially interested buyer here, would be interesting in about 64 chips?
58  Bitcoin / Hardware / Re: [TENTATIVE] - Avalon PCB Assembly - UK & Europe on: May 16, 2013, 11:47:02 AM
Interested in this but sadly unless someone does have the chips easily in the UK then I'm kind of screwed
59  Bitcoin / Mining / How many ASIC miners are in operation? on: May 16, 2013, 08:10:56 AM
For the first time even the mining pool I use, btcmine.com had what appears to be a ASIC mining running as one user on the top mining board got over 60,000MH/s.

So anyone got a guess how many ASIC devices are out there right now in operation? If you do try and show some working out of how you got to you conclusion Smiley

You can run the server yourself, and we have also hosted offers, as of:

Bits of Proof launches world's first enterprise-ready Bitcoin server

The primary API is the Bus, that speaks STOMP and is transporting Protobuf format messages, so you can connect e.g. with python, ruby or PHP, I am sure you find examples using both STOMP and Protobuf quickly with google for your choice of language.


Is there by any chance someone where that documents all the possible messages that can be set and expected results etc? Even as a really rough document?
