I've added my 5btc to that account and sent my PM to Zefir.

I'm happy for Zefir to hold escrow for my bounty. I'm away from my wallet till the weekend so i'll have to send the coins over on sunday.

3 ppl agreeing on the escrow is just not enough, imho. I have nothing agaist zephir, nor can I say anything for him. Just havent paid that much (or any) attention to he's doings in the bitcoin world. So ramp up some more support and I'll change the post.

Hi Isokivi,

sorry if I got it wrong: you as the thread owner and bounty initiator should have done the escrow, but AFAIR you refused to do that and since some of the folks here know and trust me, I took the initiative. That might have been premature, but anticipating the bitstream to be ready this week it was not too early. If you changed your mind and want to take the responsibility, I'll be glad to send you the collected coins or give you the private key to the existing address.

Otherwise (as already stated somewhere) having 50 CM1 boards I have a personal vital interest that the advanced bitstream shows up as fast as possible and the bounty gets paid. If you need to check whether you want to trust me, just visit my mining bond thread (see my sig) and read the second post.


Thanks, Zefir

All I would like to see is that the majority of pledgers agree that you are "ok" to do the escrow, got no other problems with this.

Cross post from main cairnsmore thread:

Ok, I've changed my mind... This is a little against my better judgement. I'm releasing the bitstream that accompanies the new glasswalker controller that enterpoint released. Keep in mind I have not tested this myself yet. I won't be able to do that until later tonight when I get home from work. I will confirm once I've done that.

But if any of you who are a bit more technical want to dive in and flash this along with the new controller, and let me know how it works, I'd appreciate it. As Enterpoint said, it should work in 3 of the 4 positions. the 4th may or may not work, and may be flaky.

It should mine stable at 175Mhash/s on the chips it does work on (I've tested it on one position for over 24h at a stable 175Mhash/s on my board).

In the meantime Enterpoint is still poking at the problem from the controller side, and I'm re-writing the UART core entirely from scratch which should fully solve the problem, so between the two we should have a stable bitstream very soon. Then we can just worry about driving the hashrate up to the max attainable. Then following that I'll move my focus back to my 100% "from scratch" bitstream which should offer much improved performance.

In addition, one last tidbit. I've begun work on a "from scratch" opensource version of the controller bitstream as well, with some advanced features. That should both be useful for this bitstream, and my future, but also having the opensource controller out there should help any other developers with this in the future. That one is a ways off though, it's low priority and I'm only working on it in my down cycles between the other bitstream work.

Oh and I missed the final bit, I've forked off MPBM as I prefer it to cgminer. I have added cairnsmore support to it in the form of a custom module. It's still reporting hashrate wrong, but I hope to fix that soon. This version of MPBM was tested with this released bitstream.

Here is the link to the bitstream: http://www.btcsyn.com/bitstreams/glasswalker_untested.zip
Here is the link to MPBM github: https://github.com/pmumby/Modular-Python-Bitcoin-Miner
(you want the "testing" branch)

Let me know how these work for you.

EDIT:

Quick update, here's the source. As said it's useless to most in this state, but here it is as per the license. This does not include my new fixes to my newest version, this is the exact version of the code which resulted in the 175Mhz bitstream linked above.

When I get my final version out it will include all the fixes, and hopefully be in a more easily "buildable" state, as well as include documentation on how to build. how to install, and how to run.

EDIT2:

Helps when I post the link:
http://www.btcsyn.com/bitstreams/cairnsmore_os_175_source_temp.tgz

EDIT3:

See this post on the main thread for some (very vague) instructions. I'll post better instructions once it's tested:
https://bitcointalksearch.org/topic/m.1056016

Another note from Yohan. The first ~50 boards suffer a bit more from the line noise than the remaining boards. My dev board is #1 (first board) so I may have poorer results than those of you with serial numbers above ~50. Hopefully the combined efforts from Enterpoint on the controller, and myself in rewriting the UART will fully solve the problem once and for all, resulting in nice stability on all boards.

Just a quick update, I now have a copy working at 175Mhash/s stable for a long period. But there are still some issues with the controller that are impacting communications (which is contributed to a bit by the serial comms code that ngzhang used on his core as well, which I've modified, but it's still based on the same design).

Enterpoint has released a new controller which will solve some of the problems, I believe it will work on 3 of the 4 FPGA positions stable, but I have to do some tests on this tonight before I release the actual bitstream.

In the meantime I've started another round of improvements based on what we've learned, and hope to have an optimized build soon.

Sorry for the delays.

Eberon: only 3 days and you have a working bitstream?  Shocked that's pretty amazing. Is it based on one of the existing opensource builds? or written from scratch? If so I'm curious what fMax your getting on the chips? (or did you just get super lucky and it closed timing on your first try by fluke lol). Also has this been tested on the actual cairnsmore yet?

I'll post an update once I've done testing tonight.

Let it grow up fast and we will have a first (smaller) bitstream today!
I think the faster and bigger the Bounty, the faster we will have the goal!

That's an internal information, the announcement will come shortly form the bitstream guru and he's only working 3 day's on it =D

Sorry! couldn't resist!

Ok folks, here we go.

I have put up a spreadsheet where I will account the contributions for this bounty.

The coins will be deposited to 1CM1bj7jxVskkvKE2kcw6L16rHMXL38aFm.

I am not going to send every contributor a personal address for correct assignment. Instead, send your money to the given address and at the same time PM me (forum mail to zefir or via email) with how much you contributed. That should be enough information to match the payment to sender.


Did I forget something? If not, let the coins roll!


@Isokivi: could you please copy the related info to the first post? Thanks!

Voting for Zefir. A really trustworthy guy who is running a solid mining bond on glbse.

Of course only if he is willing to do the escrow.

2nd proposal is Chefnet - he also proved himself as very trustworthy for selling lots of stuff on the forums.

Thank you for your trust and support. If majority is fine with me, I'll do the escrow.

In fact, I think the coins should be collected beforehand, instead of waiting the bitstream to be finalized. Due to the persistent dynamics in the Bitcoin world, too many potential events (like BTC skyrockets to 100$, pirate loosing all our coins in Vegas Wink, etc.) can make it harder to collect the coins later people are willing to contribute today.

If everyone is ok, I'll set up an offline address for the bounty and a Google Docs spreadsheet to account the contributions.

Cheers, Zefir

i'm cool with that

2BTC pledged as I have 2 * CM1 right now

do we give this to a 3rd party or straight to the winner once bitstream is tested?

Think Isokivi is only acting in an organiser capacity. Aslong as the winner states his bitcoin address I'm sure the rest can be done from there.

Yes, I will not be holding anyones money. Im not a long enough time member, nor well enough known to do this, should a figure the community trusts step up, it can be done, but for now I expect everyone to pay their pledges separateley when a bitstream qualifying is out.

I think we should have a member of the community holding the bounty in an escrow account to ensure the winner gets all pledged btc. someone w/ rank step up.
