7  Bitcoin / Pools / Anyone mining on 0.8 - URGENT!! on: March 12, 2013, 01:13:01 AM
[20:12] <gavinandresen> Everybody mining on version 0.8 should stop mining for now.  When you start again in a few hours, you should set your maxblocksize to 500k or less.

Hello again,

block 000000000000015c50b165fcdd33556f8b44800c5298943ac70b112df480c023 (height=225430) seems indeed to have cause pre-0.8 and 0.8 nodes to fork (at least mostly). Both chains are being mined on - the 0.8 one growing faster.

After some emergency discussion on #bitcoin-dev, it seems best to try to get the majority mining power back on the "old" chain, that is, the one which 0.7 accepts (with 00000000000001c108384350f74090433e7fcf79a606b8e797f065b130575932 at height 225430). That is the only chain every client out there will accept. BTC Guild is switching to 0.7, so majority should abandon the 0.8 chain soon.

Short advice: if you're a miner, please revert to 0.7 until we at least understand exactly what causes this. If you're a merchant, and are on 0.8, stop processing transactions until both sides have switched to the same chain again. We'll see how to proceed afterwards.

Hello everyone,

've just seen many reports of 0.7 nodes getting stuck around block 225430, due to running out of lock entries in the BDB database. 0.8 nodes do not seem to have a problem.

In any case, if you do not have this block:

  2013-03-12 00:00:10 SetBestChain: new best=000000000000015aab28064a4c521d6a5325ff6e251e8ca2edfdfe6cb5bf832c  height=225439  work=853779625563004076992  tx=14269257  date=2013-03-11 23:49:08

you're likely stuck. Check debug.log and db.log (look for 'Lock table is out of available lock entries').

If this is a widespread problem, it is an emergency. We risk having (several) forked chains with smaller blocks, which are accepted by 0.7 nodes. Can people contact pool operators to see which fork they are on? Blockexplorer and seem to be stuck as well.

Immediate solution is upgrading to 0.8, or manually setting the number of lock objects higher in your database. I'll follow up with more concrete instructions.

If you're unsure, please stop processing transactions.

9  Economy / Long-term offers / [CLOSED] BTCST Sub Accounts (PPT) paying 6.8%+ weekly on: July 17, 2012, 08:06:16 PM

Most of you are aware of the changes with BTCST come August 1st.  I am positioned to get a Trust Account but will fall short of achieving the maximum interest rate.  To that end I am gauging interest in managing sub accounts beginning August 1st.

Please PM me with an amount you can deposit.  If within the next 7 days it appears I am unable to achieve the balance threshold I will advise all and close the thread.

  • 250 BTC minimum
  • 7 day (168 hour) minimum deposit
  • Interest can compound or be paid weekly - Monday Evening (US Central Time)
  • Bonus interest rate for "untouched" deposits after 4 weeks, 8 weeks and 12 weeks anniversarys -- 6.95% maximum

Last few days I have notice one single (running 808 FW) has been reporting much lower U (shares per minute) then the two other singles on the same firmware -- NOTE BFL2 - below.

This was after almost 12 hours - so long enough to rule out short-term "luck".

I removed the single from this linux rig and ran the auto-tune on it on a windows rig.  832 was the selected FW (higher than what I had been running) but it might be a tad cooler in my office.  When I started mining (tried BFGminer as well to ensure it wasn't a CGminer issue) the "nonce light" that is visible on the right side of the unit would occasionally turn off (not just blip at each new nonce).  This seems to be completely random and will last from .5 to 12 seconds.  This appears to be the equivalent of the device turning off - hence the lower U.  The weird part is why the Hash Rate still shows fairly high.

I have since flashed to the lowest firmware (768) and it is still happening (nonce light turning off).

RMA is probably not worth it as I will lose more income in not miningg than I would gain from a properly functioning unit?!?

PS - While typing his message the light has turned off 5+ times...  Roll Eyes

PPS - BFL crew - any suggestions?!?

11  Economy / Securities / YABMC Coupon Frequency - Now 2x per week on: May 23, 2012, 02:35:26 PM

It appears that YABMC pricing could be improved by increasing the frequency of the coupon to weekly (or perhaps even several times per week a la Meni's 336 blocks).

The GLBSE contract, to the best of my knowledge, cannot be altered as trading began weeks ago.

I cannot foresee any bondholders objecting but am still kindly asking for comments.  Feel free to PM me if you prefer not posting in the thread.

So, please note your approval to change the contract to coupon payments at something more frequent than the current "every 2016 blocks at diff change".

Again, the thought is weekly and perhaps even more frequent.

Thanks in advance for your time!

15  Economy / Securities / [BTC-TC] YABMC on: April 08, 2012, 03:23:56 AM
==============Revised BTC-TC Contract===============
The holder of this bond will receive as coupons a number of bitcoins equivalent
to 60.303 60.305% PPS output of ONE MILLION HASHES PER SECOND for as long as they hold
the bond. This hashpower will be used in private computer systems owned by THE
ISSUER and used in the process of "mining" bitcoins. Every reasonable effort
will be made to pay the coupons weekly on mid-day Sunday. Coupons are not
pro-rated; you must hold the share at time of coupon to be paid. All dates /
times will be represented in UTC.  THE ISSUER can buy back the bond at any time
at a price equivalent to 105% of the highest price the bond was last traded on
BTC-TC over the previous 15 days (360 hours). Though THE ISSUER will use all
reasonable efforts to ensure value for the holders of these bonds, they are
provided on a best effort basis and as with any investment there is risk
involved. Please do not invest what you cannot afford to lose. Liability of a
bondholder is limited to the capital already invested when this share was
purchased. *** This share does not represent ownership of any company ***

Yet Another Bitcoin Mining Company

Trying to learn from those who have gone before me and provide shareholder value (yes, looking at equity and not debt).

Will be selling ~5Gh/s in the near-term and could increase to 30 Gh/s come June/July.

Again, more to follow and appreciate comments on what the community feels has been lacking (if anything) from previous offers.

20  Economy / Marketplace / [DEAD] 4.8-5.0 Gh/s Mining Contract - 50 Days on: March 24, 2012, 01:20:28 PM
Imitation is the greatest form of flattery...

I have 2 4x7970 rigs that I will offer, currently rock solid stable at 5 Gh/s but with warmer weather approaching they might need to be pulled back to 4.8 Gh/s.

  • Will point the miners at your pool of choice
  • Pool should work with CGminer (what doesn't)
  • Downtime will be appended to contract

Payment will be made 100% up front.

I have perfect eBay, Heatware and OTC ratings and have been active in the community for over a year!
