Was KNC mining LTC with a Titan farm that just went off line ?

Next LTC difficulty - 16%


https://bitcoinwisdom.com/litecoin/difficulty

I wouldn't put it past these bastardos to have been front-running us on LTC even before they shipped customer Titans.
Maybe now somebody at KNC will feel free to talk ...


If true, enjoy the lower diff til the A4's get here =(

I think its mostly just luck tho, looking at the larger pools individual stats, their hashrate is much higher than the overall estimated breakdown hashrate of those pools @ litecoinpool.org
Which usually means diff projection is just bad luck atm.

I hope the A4's miss their target release by a longshot!
The Titan is still the most profitable ASIC to date and has been for quite some time. The S9 doesnt even compare. LOL!
Think the Titan has enjoyed ... what, like a 2 year profitable mining stretch? ... not much hardware can claim that.

That ended at 12 months after last Titan sale. So my guess is by now KNC is off the hook in that it has been more then one year?

Or so I figure. Others on here with better info?

I'd say someone find a Wayback archived copy of the site and any mention of support time.

Joshua Zipkin former owner of AMT for months spanning August 2013 through their closure in Sept. 2014 touted on their website pushing their 'American Made' licensed copies of Bitmine.ch's doomed to failure A1 chip boards a 'Lifetime FREE upgrade as miner tech evolves'. We know how that went... AFAIK Josh is still stalling the Court on getting new representation since his original lawyers were relieved of Burden last year due to Josh not paying them...  Think the latest stall makes 3 or 4. Hopefully the Court will eventually tire of this and issue a Summary Judgment?

edit: I found a Wayback to AMT's 1.2THs rigs ($5,599. ea) http://web.archive.org/web/20140321031122/http://advancedminers.com/bitcoin-mining-hardware/1-2ths-bitcoin-miner/ That particular page from March 2014 claims 'Lifetime Warranty on the hash boards.  Tongue

DISCLAIMER: For whatever reason, in Sept of 2014 I was one of the damn Lucky Few that actually got A1 based rigs from Joshua Zipkin. I actually went 'cheap' and had ordered just a 512GHs rig (advertised as in-production vs the 1.2THs being pre-order only) but as all the other lucky few received, I got a 1.2THs Dragon clone thanks to contacts he made during his trip to Shenzhen in the last days (well, 3mo actually) of AMT. So I ended up with 2x the purchased hashrate with only a 7mo delay vs the others (the 1.2THs rig customers) only getting as-advertised and most (who actually got a working one) having waited since late 2013. Thank you BTC gods fer that one! Mine ran perfectly 24x7x365 up to last month when I took it off line to use its 1.3-4 kw power budget for a s7 elsewhere.

Seriously, it would be nice if they would release the design stuff into the public domain. There are a few mysteries on that board I am not going to solve without a real parts list or something.

Doubt they ever will.

With the A1 neither Bitmine.ch nor any of the more ah, successful, integrators using the A1 ever released a BOM for the rigs to the Public. All InnoSilicon has ever released is their 2-chip ref design. Sad part is, I have said documents for AMT/Bitmine.ch's original attempts at the CoinCraft rigs and as much later backed by Inno themselves, Bitmine.ch simply took the 2-chip layout and expanded the nodes per-buck regulator with zero regard to what that does to the PDN and even less to the what should have been very obvious thermal points eg needing real full sized heatsinks on top of the chips. .

Since AMT was BItmine's single Authorized dealer of the A1 and rigs based on it (AMT's verbatium clones of all boards used in the CoinCraft Desk) it was the blind leading the even blinder (AMT). Starting June 30 2014 under NDA I did forensics on them and made clear to AMT/Bitmine.ch where they and the PCB house AMT was using blew it. Had they let me look at things a couple mo earlier who knows - they might have recovered from the A1 kerfuffle. Main problem was needing more attention to detail on feeding stable power to the ASIC's as well severe underestimating of the thermals. Both easily solved as proven with the Dragons layouts. That said I still must professionally consider said BOM's including schematics and PCB layers as not for Publication since AMT/Bitmine.ch (well, what is left og them) still hold Copyright on that information. Technically I suppose I should delete it but -- it's safely archived and still gives a good lesson on crossing all the t's and i's. Especially when it comes to brand new node size (28nm) chip releases Wink

Likewise how much power does a S9 use compared to a Titan?

Why the hell are Titans so good? Did everyone else just quit or did KNC pull something out of the pits of hell itself?

(Actually with a few small changes they would break a lot less. But that would have cost about $10 more a miner, can't have that....)

As to how I would improve them:

1) Optoisolators on all signal inputs: Protects the cube against static electricity, plugs loose, ground loops, general fuckage, plugging in backwards, etc.

2) Drivers from the FPGA. You should never power signal lines directly off the output of a small FPGA. Drivers are small, cheap, and save the FPGA.

3) Two power plugs, opposite sides of the cube. Because why not?

4) Power the cube's hotel circuits and SPI lines from an on-board dc-dc charge pump. Simple as hell and you're not powering the thing from a little TPS cube on the controller. Did I mention no more ground faults?

5) Put in 0 ohm jumpers to allow you to isolate a bad die. Then you can build, test, and sell cubes with 75%, 50% dies for whatever. Looking at a dremel to cut signal lines is no way to go through life son....

The relationship between LTC and BTC is very interesting. LTC looks to be pumping over the last week or so and probably (IMO) headed higher, plus the LTC network difficulty is crashing right now.

I would conjecture that there may be some movement in CNY into LTC from BTC because of apprehension about what will happen to BTC value and/or the BTC network after the halving.

LTC mining looks set to become more profitable.

It would be nice to have full source code to the FPGA subsystem too.
