I am trying to get better price from them, depends of the number of rigs ordered also.
Right now, those are prices in EU with taxes and shipping included in EUrope.
However, I am not very excited about their prices...
China is full of Antminers, Avalons, Bitmains and Bitmines, but still they try to keep the prices high.
But there is place for strong negociation!
When I get an idea about how many rigs to order I will let you know new prices.
If no requests, no orders will be placed.

Bitmain Technologies Limited is proud to announce ANTMINER S2 that features 1TH/s Bitcoin Miner, consist of high-density chip chains and ultra low power consumption.

AntMiner S2 is using the state of the art BM1380 chip, targeting the best possible power efficiency. S2 is built into a 4U size box, and it will come with PSU manufactured by Enermax. S2 will be very convenient to deploy. S2 is still running quietly.

Since November of 2013, BM1380 has been proven to be the most effective IC on the 55nm process among all competitors, even comparable to the most Bitcoin Mining ICs developed on 28nm process nodes. Our first generation Bitcoin Miner, AntMiner S1, demonstrated low power consumption but a high performance.  Currently S1 is most popular miner for mining enthusiasts.  S1 is currently deployed in large binary trees structures within the private and public mining pools servicing 20.3% of the entire network hash rate.

The 1st Batch of AntMiner S2 will be shipped out on April 1st. AntMiner S2 will be available in the global market for a price of $3,899.

Our website store located at https://www.bitmaintech.com.


AntMiner S2 SPEC:

• Hash rate: more than 1,000GH/s
• Power consumption: 1,000W from the wall
• Power efficiency: 1Watt/GH/s
• PSU: 1000W produced by Enermax, 80PLUS gold
• 4U Rack
• PSU inside
• Plug and Mining
• Stable and quiet

they provide S2 at the price of 3599,  shipped in 10 Apr, you tell me which one is worthy to buy, 1 T dragon miner priced 4100 and delivered in 19 March, or S2 priced 3599 delivered in 10 Apr. Now dragon 1T miner can earn 0.12 btc each day, and  you can earn more than  2  btc (value 1200$).

Not that I'm aware off, most are September orders

And it seems they ran out of power supplies

How is that even possible?

They knew how many orders were queue up. I can understand there is a delay in the custom PCB that needs a new revision or that the ASICs are delayed, but power supplies? What's next, no screws for the cases?

Bitmine says they own it. Innosilicon says Bitmine licensed it. Innosilicon isn't a brand new company. Bitmine is. I'd give the benefit of the doubt to Innosilicon.

What is actually Innosilicon's current position on this matter is this, and I quote from their web :
"Innosilicon Announce its 28nm Bitcoin Mining IP core in Production
Innosilicon is proudly announcing that BitMine AG, a leading bitcoin mining system supplier, has licensed its ultra low power Hash IP Core for production at GF 28nm HPP process. This IP is designed from scratch using patent pending, customized VLSI computational Marco cells developed to squeeze the best possible power efficiency in 28nm. Its ultra high power efficiency and thermal reliability allows BitMine AG to pack just the right amount of innovative hash horse power inside a A1 CoinCraft ASIC. The availability of this 28nm hardened IP core instantly raised the bar in a crowded 28nm bitcoin mining ASIC field."

This might mean, that :

a) Bitmine.ch has patented (patent pending), their HPP proces (sublicenced from GF and forked), based on their Bitcoin Mining IP core
b) Innosilicon has given permission to Bitmine.ch to use their ultra-low-power Hash IP core for 28 nm DIE for chips produced by Innosilicon for Bitmine, and probably given only to Bitmine and nobody else.
c) Who did customized VLSI computational Marco cell (power train in 28 nm) - Synapse, Verisilicon, Innosilicon, Bitmine or GlobalFoundries is not known to me at this point. Also not known if this customized VLSI method is patented by someone.

Even though somebody could obtain licence from Innosilicon for power layer, other layers are still not Innosilicon property, so without Bitmine's sublicence on final design, full tapeout of cloned chips is not [legally] possible.

It has nothing to do with BRANDNAME - "COINCRAFT A1" as s BRAND, but with TOPOGRAPHIC DESIGN OF INTEGRATED CIRCUITS, which is SEPARATE LEVEL OF INTELECTUAL PROPERTY PROTECTION FROM BRAND(NAME) PROTECTION, patent pending according to Madrid Convention of the World Intelectual property organisation. Patents are accesible from WIPO portal, and they are many, and non of which are the property JingTian.

So have these knock-off chips been reported to Chinese authorities?

Doubtful. Innosilicon was the one who actually engineered the chip.

Authorised distributors of bitmine tech: http://bitmine.ch/?page_id=5204 - unless the chips were sourced from one of these guys or bitmine themselves it's corporate theft.

Bitmine have already made themselves quite clear on the issue and until they've made a statement retracting the previous statement it's much more likely the the statement was deleted/moderated rather than retracted. Furthermore, we have yet to hear anything from Innosilicon to suggest that they have obtained the rights from bitmine to produce these chips for sale.

Certainly it's plausible Innosillion also have the rights to sell the chip, but it is also certainly plausible Innosilicon does not have the rights to sell the chip. In the absence of an official statement from Innosilicon contradicting the official statement from bitmine and the presence of the well known culture of rampant IP theft that goes on in China, on the balance of probabilities, it is much more likely the Chinese machines using 28nm A1 chips from Innosilicon are the product of stolen property and therefore illegal to receive and/or possess in most common law jurisdictions.

Customers have the right to purchase goods that are 100% legitimately manufactured. I would not want to buy a car that has been assembled from stolen parts.

Pretty much everyone uisng a MCU solution is a copy from us.

Klondike_bar, I do not agree with you. Asking for a clarification and Calling FBI are totally different issues. You cannot call FBI to involve until you have valid proof, or else you could be sued for defamation.  Both JT Miner and Bitmine seems use the same A1 chip from a Chinese suppliers and as I understand, Bitmine do not have the patent of the chip. And it seems that Bitmine does not deny it. This seems a fact.

I am tracking new generation of 20nm ASIC miners which is available for US miners currently, JT miners is one of them. Even though JT Miner is not in US market yet, they do have real miners running very stably and they has more than 1000 miners order which are waiting in line.  It is a promising supplier which our US consumers should expect. Therefore we should focus on the fact not the rumor or emotional assertion. We do not want a scam and at the same time we do encourage the good 28nm miner suppliers to join to compete so we have more choice, especially the promising miner suppliers.

On the unit i have it looks linked to Innosilicon.

I've looked through this post, but I'm a bit confused... I'm trying to figure out what everything is and how much they cost and what is shipping/when.

What I've gathered, there are currently 4 units? LA5U, LA3M, LA6M and LA1THS?

The LA3M runs around 3-4 MH/s and the LA6M is actually just two sets of the LA3M.

What is the LA5U?  How much does it cost, and how fast does it hash (Scrypt)?

What is the LA1THS?  How much does it cost, and how fast does it hash (Scrypt)?

A quick informative reply would be greatly appreciated.  I'd like to place an order, but I'm still not sure about the best way to do that.  I've seen multiple people suggest PMing the OP (asiaBTC) and it looks like they are working on a website/store, if I don't want to wait for customs, is Zoomhash reliable and are they priced similarly to ordering myself?

Thanks!

Exactly.

4) Will my unit perform as well as the demo unit
5) Will my order be fulfilled before they run out of stolen chips
6) Will I get in trouble with the police by having this unit, if it makes it past customs
7) Will I need to justify to the police why my other mining hardware are legitimate and should not be seized

Why no video of the miner to prove it is working? What is the identity of the person selling? If the device generates a good revenue, why is being (re)sold?

I think the that the typical consumer is really only going to care about:

1) When can I get it?
2) How much does it cost?
3) Will it do what I need it to?

Your miner is not from us and it is not the same as JTminer. Basically, the JTminer with smaller size is much stable and can do overclock. Please ask the suggestion from who you bought it if you want to do overclock. We are not responsible for what is not from us. Thanks.

Bitmine and Innosilicon worked together to produce the chips, so both of them have rights to produce/resell the chips.

Precisely, we are the owner of the IP inside the A1 chip and the major contributor to the know-how of the inner workings that led to its development. We are aware of things like the one happening here and we even made a press release news concerning this matter:

http://bitmine.ch/?p=5178

Whoever purchases these does that on its own risk and may be liable in its own country since we hold IP on that.

Yes, that's China.

I want one of these but don't have enough BTC left, spent it all on Ants!

I agree. Both Bitmine and Bitmine and Innosilicon worked together to develop the chips, and no-one has posted any proof as to exactly what legal rights Innosilicon has to resell the chips, but it's certainly plausible that they do have some resale agreement based on the contract between the two companies. Innosilicon could have paid for part of the development in order to be able to retain some ownership of the IP.

It sounds like QuestionTime is simply spreading FUD to try to show down a potential competitor to Bitmine. Either post proof to back up your claims of IP theft or STFU.

Thanks for reasonable people's support and also thanks QuestionTime for a debate to make things clear. BTW, QuestionTime made a big mistake to challenge us instead of other agent to sell copycatted miner since JTminer is the original .

A lot of information come out, let's do a summary:
1. dimension: 426*380*200, smaller size than other miners.
2. Can do overclock.
   i. extra power supply can give you the ability to over clock. The boards are equipped with 32+A current capacity power supply per chip:), in 25G/s mode, it only consume 20A per chip. so it has room to do the over clock.
   ii. Linear Tech power supply + careful design gives the ripple only at 20mv:), it will stabilize chips using the higher clock without too much HW error
  
   Kind reminder: For those who bought a copycatted miner from other reseller, please be very cautious to do overclock, it will burn the chip and board.
3.  JT miner spend lot's of effort in the firmware and Pi side. they use the ST MCU. the firmware is written from 0. after JTminer use the ST MCU. some vendors' solution seems to have interests in ST MCU too:)
4. The Pi board can drive up to 8 boards (in lab we do), and each MCU to control the two SPI high speed chain. in this way, give the whole system more flexibility and scalability.
5. We do not have authorized distributor now. Only a few sample units are being sent out.
6. The order for 1200T is to be completed soon. We also have chips in stock for future business.
