1  Bitcoin / Hardware / USA Import Duty on S9s? on: July 04, 2016, 05:23:35 PM
My B45 order of S9s has hit the United States.  I've been buying miners from Bitmain since the S3, and this is the first time I've had DHL tell me I owe import taxes. Apparently the message is coming DHL Canada, perhaps because its the 4th of July Holiday here in the USA?   I tried calling Customer Support, which is suppose to be open, but got routed to an old DHL Canadian telephone that told me to update my phone records and call 1-855-DHL-SHIP - very strange.

Anybody else having problems today?

Is it normal to have to pay an import duty, or is this likely some type of screwup because DHL Canada appears to be dealing with things today (and Canadians always pay an import duty).

2  Bitcoin / Mining support / Problems upgrading Antminer S7 firmware on: January 21, 2016, 05:28:43 PM
Hello all.  I have a pair of Batch 1 Antminer S7s that I can't seem to upgrade with firmware.  I'm guessing I'm doing something stupid, and would appreciate someone pointing out what.

I've gone to the Antminer download site and grabbed both the October and December 600M firmware files (.gz).

I go into the System->Upgrade panel, browse to my download folder, and select one of the .gz files.

I click "Flash Image" and get:  http://puu.sh/mEegG/d9c7dee733.png

The system stays that way forever.

Going back to the system overview shows the original firmware running (September 15th version).

I'm trying to fix an annoying problem where the miners occasionally stop mining, beep that the internet is down, then resume 10-30 seconds later.  This happens, randomly every hour or so, sometimes a couple of times an hour, sometimes not for several hours.  Both miners are doing this, although I've never seen it at the same time.  If I didn't know any better, I'd say they had duplicate IP addresses, but they are statically configured with unique IPs.  I have other Antminers (S3s and S4s) running through the same switch without problems - its just the S7s.  Of, each time this happens my mining pool tells me I've lost a miner, but just for one polling interval.

Very oddly, we had a power outage a week or two ago, and things were stable after the power came back.  I moved the network cable coming from my machine room (where all the antminers reside) from my general switch to a new firewall and the problems started back up again.

The "sometimes" nature of this issue is driving me mad (as is the random beeping!).

In any case, I'm hoping a firmware update will resolve this, but can't get that working.  Not a good day.
3  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN][1CR] 1Credit: New wallet as of block 16175 on: May 02, 2015, 11:27:39 PM
All 1Credit users should immediately download the latest wallet from http://www.1creditcoin.org or from the source at https://githhub.com/1credit/1credit.

This wallet was announced via Twitter and the website prior to block 16175 and is now mandatory.

The great news is that blocktimes have stabilized.  The original swing was just too wild to make the coin reliable.  By significantly deepening the depth of the Kimoto Gravity Well algo, we appear to have stabilized the coin.  24 hour block averages are now dead on target.

Thanks for your continued support!

4  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] Independant Miners Alliance Official Launch Notification (IMACredit coin) on: September 04, 2014, 02:02:57 AM


Welcome back to Independent Mining!

This coin is for everyone with a normal PC or server wanting to mine without being obliterated by Corporate Data Center ASIC based mining!

What is IMAcredit?
----------------

IMACredit is focused on creating a truly ASIC free and GPU resistant crypto coin.  It accomplishes this goal by utilizing the N-Scrypt algorithm with a much bigger N than any other coin to date.  At launch, N=16.  This is 2 higher than the latest ASIC technology will support and high enough that current graphic miners will crash with stack overflows.  e.g.  This is a CPU only targeted coin.

What is the Independent Miners Alliance?

Well, honestly, its the name of one of the four factions in the apparently defunct game "The Crypto Void" by 1BillionHash.  However the name also reflects the goal of having a coin that is independent of the big data center driven coins like Bitcoin and the popular Scypt based coins.

Key Stats:

    Launched on 9/1/2014
    256 second (~4.3) minute block targets
    16 coin payout per block
    No half life
    subsidy constant for life of coin
    ~92B coins (limit of 64 bit math)
     Every block to retarget difficulty with Kimotos Gravity Well algorithm
    ZERO pre-mine, ZERO special blocks, no IPO, nothing hidden,  RAID RESISTANT

As mentioned on the Home page, IMACredit is designed to be CPU bound - a coin for the masses.

Due to its high N factor, each hashing process will require 16MB of memory.  Nothing significant for today's PCs, but an absolute killer for ASICs.  Early testing has also found IMACredit to resist GPU usage, with sgminer crashing due to a stack overflow within minutes.  This testing also shows substantially smaller khash rates than most have gotten use to:  Where bitcoin ASICs are measured in GigaHash, and scrypt ASICs are measured in 10s or 100s of MH, and GPUs generally deliver 100s of KH, IMAcredit's wallet will hash in the 10-100KH range.

Let us be perfectly clear:   This is a coin for the masses, designed to require large numbers of users to meet its block time target.  No handful of users will be able to dominate this coin.    Until N-Scrypt mining code like sgminer implement fixes GPUs and Pool mining will not make sense.  Pool mining may never make sense - this code is designed to be run from the wallet!

Hashing Algorithm:  N-Scrypt, initial N=16.  Codebase tested through N=20 representing 7 generations of ASIC's to come and expected to work at higher Ns.  (for the coders out there:  Heap based scratchpad allocation vs. the typical Stack based which would break at N=15)

Difficulty Algorithm:  Kimoto Gravity Well, with Time Warp Patch

6  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN][1CR] 1CRedit Coin Relaunch on: June 09, 2014, 05:41:27 AM
Today, we are announcing some dramatic improvements to the 1CR coin to address some of the impediments to adoption that have occurred in the past few months.

The coin was designed to be very secure, have little adoption by the multipools, and to be used for longer term investment uses (such as banking in the simulated worlds of OneBillionHex. One of the chief complaints to many of the pool operators was the extended time before pool users were able to receive their first payouts.  This was due to two security measures of 1CR: 1) 256 required confirmations, and 2) a defensive difficulty retargeting, designed to discourage mulitipool raiding of the coin during low diff periods.

Without pool cooperation, we found that general adoption of the coin was low, and the coin would be mined in a very dramatic roller coaster difficulty fashion, which led many to give up.

After careful lab testing – a new source code has been release, that goes into effect at block 4000 – probably within the next day or so.

The new source code will reduce the confirmations to a still very secure 156.  Note that most wallets add 20 to this.  As well, the difficulty retargeting has been ‘dampened’ to still discourage multipool raiding but provide a more consistant coin time.  We hope these changes will encourage pool owners to re-adopt the 1Credit Coin (1CR).  This should start to produce a bit more coins daily, and allow the pool users to receive their coins in a targeted 25 hours, versus 3-4 days the old settings yielded.

The coin is still a very rare coin, and is designed to have minimal forks (several months old and still not a single fork!), and minimal risk of double spend attacks.  There was zero premine, there are not secret payouts in the code, no IPO, and the only way the Dev or the team can make money on this is the same way you can, mining the coin.  It has held a pretty good value on Poloniex so far, even with the earlier design inconveniences, and we expect it to be a great coin to buy and hold as it gets integrated into the Crypto Ecosystems.

We need some community support, in the form of a few new pool operators, to really make this relaunch a success.  PM the Dev and he can introduce you to a few experts if you need a hand.

Mission:
•   To create the investment coin for long term security and stability
•   To avoid Mulitpool Mining that drives the value down
•   To create a stable coin to encourage long term mining (set it and forget it)

Supply:
•   To date – there are less than 4000 coins
•   Each block generates 1 new 1Credit coin
•   No IPO
•   Total Supply – The current block number!  One coin per block of course!
   
Current specs:
•   Algorithm: Scrypt PoW
•   Started: April 19th
•   Blocktime: 8.5 Minutes
•   Blocks confirm: 156 confirms (most wallets add 20)
•   Transaction Confirms: 16
•   Retarget: every block (Modified KGW)
•   Block rewards: 1

7  Economy / Service Announcements / [ANN] Gawforum.usertalk.info is open! on: May 31, 2014, 04:09:32 AM
An unofficial user run forum has opened for discussion of GAW Mining products and services.

GAW mining produces a number of custom ASIC based products that apparently use the same chips as the Zeus miners, presumably using different board and configuration designs.  As such, Zeus customers and anyone using zenminer fucntionality are also welcome to join in, since we are likely to have similar issues.

Please come join us at http://gawforum.usertalk.info and enjoy the benefits of being in a community of miners with similar equipment.

The forum runs under normal rules:  be polite not abusive, and state facts not fantasy (unless you in the "anything goes" forum of course! <smile>).  Moderation is expected to be minimal and mostly used just to clean things up once the content is obsolete.

Spammers and trolls, please enjoy life elsewhere.

Thanks!

8  Alternate cryptocurrencies / Altcoin Discussion / Support The Water Project and help 1CR at the same time! on: May 19, 2014, 05:39:19 PM
Voting is currently open at https://www.coinpayments.net/vote

If your not familiar with coinpayments.net - they are a clearing house for vendors who accept bitcoins for their products.  Check them out, you may be surprised by how many vendors they have!

In any case, this is one of those 100% legit events.  They donate all voting proceeds to the Charity after converting it all to BTC.  They accept votes in BTC, LTC, and DOGE.

You can only vote once, and can only vote for a single coin.  We would appreciate if you voted for 1CR.

Donation amount is totally up to you, with a minimum of 0.001 BTC equivalents - that's like 45 cents - everyone can afford to do this.

So please help Charity, and help 1CR in the process.

Thanks,

The 1CR Team.

Oh... don't know about 1CR?  Check out http://www.1creditcoin.org and/or the forum off that page.
9  Alternate cryptocurrencies / Altcoin Discussion / www.multicoinpool.org now supports YACC and 1CR as exploratory coins on: April 29, 2014, 08:25:40 PM
Multicoinpool.org has recently added both YACC and 1CR to its exploratory coin option.

Multicoinpool is primarily a "for profit" pool that shifts between the most profitable coins in its databases.  It supports both SHA256 and Scrypt coins that are marketed on the Cryptsy exchange and features both direct payment and auto-trade capability.  The pool operator monitors the overall pool hashrate and only selects coins that can be potentially mined within 2 hours - enabling it to compete with larger pools by mining lesser known coins.

Daniel, the developer, has heavily modified the base MPOS environment to provide this and a number of other unique features, like profitability charts that explain the why and how coins are selected.

New to Multicoinpool is "explorer" coins.  These are coins that do not meet the requirements outlined above, but that the pool supports by request so that its customers can "one stop shop".  Currently included coins include both YACC and 1CR as well as DGC.  I believe the eventual plan is to allow selection of explorer coins as a percentage of hash:  e.g.  You will be able to state that you want, for example, 80% of your hash going to maximum profitability and 20% of your hash going to explorer coins.  Currently however, explorer coins are enabled by worker.  If any explore coin is enabled, that worker will focus solely on that coin.  If multiple explorer coins are selected, the worker will randomly pick one every 7 minutes, balancing the overall work between them over time.

Other explorer coins are expected to be added soon, with CGA being the next likely one.

In general, it is always recommended that if your using pools, you use more than one either in backup mode or in rotation.  I personally prefer rotation since this helps balance loads and spreads block finds out - making for a better coin network with less chance of forking.

Current known YACC pools:

10  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN][YACC] YACCoin 0.9.1.3 maintenace release on: March 14, 2014, 01:04:28 AM


March 23rd, 2014 Maintenance Release

Highlights include:

* (2) addition checkpoint hashes for added blockchain protection
* Client version numbering change in order to allow us to track which client people are connecting with.  This will be incremented new versions become available.
* Protocol version increment.  This will occur anytime new checkpoint hashes are added.  This will allow us to force the wallet version should the blockchain ever fork.  Not a perfect solution to that problem, but we are confident it will help.
* Connection settings tightened up.  Connections will be banned after 16 abuses instead of the default 100, but only for 4 hours, vs, the default of 24 hours.
*  Connection age will be limited to 3 days in your peers.dat hopefully eliminating all the wasted time associated with trying to connect to someone who hasn't been on the net is a weeks.
*  10 connection failures over 2 days will be allowed vs. the default of over 7 days.

We believe the above changes should help speed up resyncs and reduce overhead of trying old, stale, connections as well as provide us some important debugging and control points should we need them in the future.

YACCoin History:

Since its original launch on February 12th, 2014, YACCoin has evolved.  We are now using the Kimoto Gravity Well for better control over difficulty, and have disabled UPNP for the protection of our user base.  Of course, as the block chain has grown, we have been adding additional checkpoint hash keys to protect it.  YACCoin has always been, and will always be, 100% IRC free.  Like disabling UPNP, our development team believes the use of the IRC network unnecessarily exposes our user base to potential security threats.

We are pleased to announce that YACCoin was chosen as the first of eight cyber coins to be used in the new upcoming 1BillionHex game.  Mine now and spend later in the game!  It will also be the first alt coin to be accepted for digital download payments on 1BillionHex.com.  https://www.1BillionHex.com/

YACCoin is simplicity itself for Windows users - just grab the executable and go.  No zip files or special directories needed.

CPU miners will find that the current YACCoin difficulty allows for successful CPU mining on a weekly timescale.   All mined blocks are rewarded with 1024 coins!  The development team continues to seek ways to reward CPU miners since they greatly enhance our network.  Please post your suggestions on our forum!

You won't ever have to worry about adding "Addnode=" statements into your configuration file either - The YACCoin network has multiple seed nodes and a fully functional DNSseed system enabling rapid, automatic, connections and syncing.

As all real developer based coins should have, YACCoin has a fully function -testnet network available if you wish to utilize it.

Of course, full source is maintained at https://github.com/yaccoin/yaccoin.

Windows, Mac OS, and Linux wallets are available at our official website in the download section, although we highly encourage Linux/Unix users to compile their own from the git source.

The YACCoin team believes that security, sustainability, and growth are the most important factors for the coin and are continuing to search and implement methods of improving all three.

Please come join us!

11  Alternate cryptocurrencies / Announcements (Altcoins) / YACCoin up, running, and stable on: February 22, 2014, 06:43:07 PM
Hi all.  Just wanted to make it official by posting here:  YACCoin is up and running.

We launched at ~1000 blocks on February 12th, had a great few hours of CPU miners being very happy before the pools sprung up and the normal launch hell broke lose.  We have successfully converted to Kimoto Gravity Well, and, of course, wish we had launched with it, but that is now history.

Pools came and went and came again.  We now have one stable public pool, at least one private pool, and many individual miners.

Please visit our website at http://www.yaccoin.org for more details.

As of this posting:

{
"blocks" : 14307,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.35780583,
"errors" : "",
"generate" : true,
"genproclimit" : -1,
"hashespersec" : 2253,
"networkhashps" : 17159634,
"pooledtx" : 0,
"testnet" : false
}

An artwork contest is informally under way and we expect to release at least one update (See the forum for the currently leading contender) that will just be a more formalized "coin look" release.

Basic info:

    Scrypt Algo
    1024 coins per block found
    23.5 years of coin generation
    2 year half life
    1.5 minute block time (90 second generation time target)
    Kimoto Gravity Well based difficulty adjustments
    8.4 Billion total coins
    100 confirmations for new blocks
    6 confirmations for transactions

We have a blockchain explorer available, the public pool, full DNSseed support (5 nodes), a forum, twitter account, Windows, Linux & MacOS wallets, full github source code access, etc.

Cheers!
