A project of ASIC bitcoin mining is ongoing by our group, named btc-garden (www.btcgarden.com).  At the moment, we are at the stage of TAPE OUT.

We have started our project since Feb.2013.Also, according to our timetable, we will have around 100T hashrate online on this August or September as our best situation. The following paragraphs are written to give out a brief introduction of this item. A relative detailed version will be posted on this board & our website at the beginning of June, 2013. Any questions or advices are welcomed in this thread.

A brief introduction

1.   About Us
BTCMAN (WWW.BTCMAN.COM, portals & information site in Chinese,with 15k registered members by far) is a full time bitcoin-related team from china; we currently have a decent PV of our forum & the main site.
 

In terms of the project of BTC GARDEN, all of our core members were graduated from CAS (Chinese Academy of Sciences), after graduation, some of them stayed there to do research works till now, while others make a living at Intel or Nvidia, I.e. we have both R&D Personnels from institute and practical engineers from mature industrial system. From a technical perspective, the difficulty of this project is really easier than many of our previous ASIC projects.
List of Us
ID：W.J, team leader, 8 years experience in system design.
ID：D.M , 3 years Intel experience in VLSI design( front-end and back-end ),5 years
Experience in system design and software design. In charge of ASIC design and software design.
ID: Xrange.G, 8 years Spreadtrum experience in VLSI design (front-end). In charge of RTL design, RTL verification.
ID: Kevin.S, 12 years HuaWei experience in VLSI design (front-end and back-end). In charge of FPGA verification, synthesis.
ID: Y.S, 4 years NIVIDA experience in VLSI design (back-end). In charge of physical design.

2.   Tech Exhibition
a)   Project Milestone
i.   March 15th: We also signed the confidential contract with the IC manufacture and got the library for synthesis and layout.
ii.   April 10th: Our RTL design, optimization and simulation were finished. We have some data to predict the specification of actual chips.
 

iii.   May 16th: layout Version 1 finished.

4.   Q & A

Q:Do you guys have any relationship with ASICMINER or AVALON?

A: No, but we do have a similar background. We also had some contacts with them through either IM tools or in person, although some of their thoughts / behaviours are hardly accepted by us.

Q: how to guarantee the transparency ? I know that a 100% provable openness is impossible in BTC world,but what can you offer as your best?

A: A daily video will be upload every day to show out how much we have digged out. It will be better than pure pictures or photos which can easily be photoshoped. We may adopt a lot of methods like this to reduce the probability we do anything dirty.

Q: Is there a list to show out all the solutions of those possible accidents? For instance, chips broken within first year; unexpected huge hashrate influent our income so much;equipments in the machinery rooms get stolen; Website get hacked;how long time is needed for deploying the first 100T;how to define the”first year”, if there are some offline-days in the first year, is any kind of compensation/refund offered…etc.

A:As we metioned on the 3rd part, we still haven’t decided which mode to choose yet, if we finally prefer Mode B to A, then all kinds of questions may be posted on somewhere at our website and will be replied asap.



Again,any questions or advices are welcomed in this thread.

Well this looks promising to me.

Good luck !  Will be following your announcements.

RIF, dude, the question regarding sales and chip speed are answered quite clearly, if you take the time to read.

130nm isn't outdated until it's outdated. Others may be WORKING on 65 nm technology, but it is still in R&D. It's not available yet, and we don't even know how much progress is actually being made on that.

This thing sounds like it's near release, and if that's the case, the technology will still be current at launch. Who is to say they aren't already looking to the future for a smaller wafer size as well? Cross that bridge when they come to it. For now, there's still a HUGE demand for ASIC, and 110-130nm is still plenty acceptable, assuming they're able to get their equipment online/selling within the next few months. Hell, people are still buying GPUs and FPGAs, and there are people paying 2BTC for the ASIC Miner 300Mhash USB unit. Anything even REMOTELY competitive in price with that nonsense will sell like hotcakes.

They said details will be available in June. Sit tight and let's see what they actually have to show us.

have you already arranged for the infrastructure to deploy your hash rate? the power and physical space needed for such a deployment is one of the biggest concerns for an effective rollout.

can i ask how much the project cost you ?

Took a few moments of puzzlement and contemplation, but do believe for the graphs, PV is 'page views' . Not sure of the other metric. But the graphs show the amount of traffic their site is getting in the lovely China part of the world.

So MODE B is just a hosted situation, meaning they don't ship you the unit correct?

Cool. How do I short AM?

Nope if you paid attention they are 64 pad chips at 400mhz that they seem to be designing themselves looking at the pics posted.

In a lqfp no less, ie something like this.


At last a seemingly properly professional development without daft amounts of pre-hype.

1 vote for lifelong dividends.
