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

Pools:  http://mpos.imacredit.org (stratum+tcp://mpos.imacredit.org:10052) - This is a VERY basic, lightly maintained pool.  We REALLY REALLY recommend doing local machine mining.   If you locally mine, give it time:  expect to find blocks per week, not blocks per hour.

Like all high quality coins, IMACredit maintains an active DNSSEED network.  You should NEVER have to specify addnodes.  All wallets should work upon launching.

All rejects using scrypt n miner.

you fast

CPU miner rejects as well.

Hope you set N=16 for your miner.  Would also love to know which miner your using, most we tested crash with a stack overflow running with that high of an N.

Those mining that we are aware of are all using the coin wallet to do so (both Windows and Linux)

How do you set N=16 for your miner? What miner VertMiner?

I tried mining with the wallet and nothing is happening. No blocks being found with a i7-960

Give it awhile.  This coin has a 256 second block time, and steam is still building to achieve that.  Currently 63 blocks have been found.  The rate is improving as more people join in but we just don't have enough yet to achieve target block times.

Please let any of your idle CPUs work on this coin.  I'm personally expecting to mine blocks per week, not blocks per minute.  This coin is for those interesting in putting their otherwise useless (for Bitcoin) or virtually useless (for Litecoin) or marginally useful (for other scrypt coins) to good long term use.

As with any other coin, the most profitable way to mine is solo mining.  That is also currently about the only way TO mine this coin.  We have not found a public n-scrypt miner that can handle N=16, although we have not tested them all.  Technically: Most current miners will need to change their scratchpad allocation to heap based instead of stack based.  Its not hard to do, but the 16MB scratchpad associated with a N of 16 eats through stack space pretty darn quick.

Note that since the scratchpad is 16mb in size, this coin is highly influenced by the Memory architecture of the system and number of cores more than the speed.  Things like L2 cache or Intels "Smart Cache" are overwhelmed by the coins memory reference patterns.  THAT is why the coin is ASIC proof and GPU difficult.  (All currently announced, much less delivered, ASICs can only handle an N of 14 (sometimes marketed as N of 16384 but that is 2^N, not N - not that marketing folks care.))

This is the coin to mine if you want to fight back against large Corporate Data Centers talking over mining.  Help us help you!

Varies by miner.  For sgminer its a setting in the conf file, but I can attest that sgminer dies with a stack overflow (as expected).

Highly recommend you use the coin wallet to do your mining, either the windows one or the linux one.  Website (http://www.imacredit.org) has the details.

Note that most coins, like vertcoin, use N=11. This coin is MUCH more memory intensive and slower to mine, but its slower for everyone, so remains equitable.

92 billion coins

Why even bother ?.

Quote from website


So another BBL-PPL coin.

CPU vs GPU...

 :D :D :D :D :D

Because the true rarity of a coin is defined by the number of coins in existence at any given time.  

If you goal is to own all of the coins, then you are right, don't both.  If after a year, when about 2M coins exist, your subset will still be significant.

This coin has NO half-life, no scams associate with half-lives, etc.

The coin is designed for the long term, not to max out after a few weeks or months of mining.  And if, like some, it maxed out in 24 years, do you really care if it maxes in 24 vs. 48 vs. 96 vs. 1M years?

Cassey

More like CPU - yes, GPU - maybe, with a small advantage over CPUs (perhaps 10X, not 200X), ASIC - never.

If ASICs ever get close, say in a few years, a one line change in the source code and a new wallet is all that is required to regain the distance.  This coin has been tested up to N=20, its works just fine.  Also, with current technology and N=20, it hashes at about 1000 Hash/HOUR.  That was not viewed as practical.   N had to be 15 or greater to provide protection from this upcoming generation of ASIC, so N=16 was chosen to give the coin a few years to grow before technology caught up and required a new wallet.

This coin is NOT a Pump & Dump, there is no way for raiders to jump and and mine millions of early 'easy' coins, hold and then dump them.  In fact, early users are penalized just a bit by the slower block times associated with insufficient nethashrate.  Of course, the chances of finding a block are much greater for early adopters, just the rate of block finds on a network level are slower.

So crank up a wallet, run it in background, and come back in a week to check your balance - then rejoice in doing something different and in helping to prove that distributed mining IS the right way to generate coins.

Cassey

 8)yes, GPU

Please let me know if you find a miner that doesn't stack overflow at N=16.  I have a half dozen GPUs I'd love to assign to IMACredit.

We tried SGMiner, but even at an intensity of 8, it crashed within minutes when N was set to 16.

Cassey

Fully agree with this but you make a point of saying that this is for the 'miners' and not the large datacenters or corps. The problem is that its just not true, reality is that you are just going to switch one group (ASIC farmers) to another group (botnet owners, CPU Farms).

i can not clear this coin is cpu or gpu

I agree, that is a risk.  Not sure what anyone can do to prevent that though.

The math works out a bit differently to.  A corporate data center like GAW runs can easily have 1M times as much Scrypt ASIC based mining power as a home user would have with a CPU.  How many botnets are out there that could load a 22MB executable onto a million infected PCs, run it, and not have it show up on the taskbar?  Especially an executable that eats 100% of the systems CPU?

Will some try?  I suspect so.  

Could someone go to Amazon Web Services and rent 1000 VMs to mine?  Of course they could - but even that will hopefully represent a small fraction of the potential miners out there, and it wouldn't be free to the AWS renter.

Admittedly, success of this coin is dependent upon a large number of miners each going in with a relatively small amount of hash rate.  Will that happen?  Well, it won't without a coin to try it with.  It might either on its own, or based on the success of "The Crypto Void" game by 1BillionHex when that becomes available.

Cassey

CPU.

In theory, with a bit of effort by the GPU miner software developers (like bfgminer, cgminer, and sgminer), GPUs could be used - but no software has been identified that currently supports the high N level used by this coin.  Even when they do, because of the high memory requirements of a N=16 n-scrypt coin, the advantage of GPUs will be limited over CPUs.

Cassey

??? what happen

E3-1230 V3

That is not unusual, its hashing.  Just check your CPU usage.  Best I can tell its just a base sampling issue associated with the slow hashing rate this coins yields.  On a Unix wallet I watch regularly, I see it bounce around between 0 and 20 or so, occasionally hitting 120, but rarely.  I'll look into changing the units displayed so something more meaningful shows up - perhaps changing it to hash/minute?

For example, from my PC:  http://puu.sh/bkAuV/839742f46c.png  Note is was showing 75 on the previous getmininginfo, then 0.

Its a new coin, I'll work out these type of kinks as we find them.

Update:  Here is the problematic code, now just need to figure out what we can do about it:

Value gethashespersec(const Array& params, bool fHelp)
{
    if (fHelp || params.size() != 0)
        throw runtime_error(
            "gethashespersec\n"
            "Returns a recent hashes per second performance measurement while generating.");

    if (GetTimeMillis() - nHPSTimerStart > 8000)
        return (boost::int64_t)0;
    return (boost::int64_t)dHashesPerSec;
}

:( look like mined one block
It will take an hour

We definitely have not reach minimum mass to achieve target block times.  If you have more idle cpus, please assign them, and ask your friends to do the same. 

If you have GPU rigs mining other coins, consider having their CPUs mine this one, that would help a lot too.

Be calm, don't panic.  The coin is only 2 days old.  Its doing fine.  It just needs time to build up some momentum.

Cassey

On the zero hashes per second issue after doing a setgenerate:

Please wait at least 8 seconds before querying the hashrate.

I'm playing around with different timings now to see if perhaps a bit more patience (like a 30 second delay) will generate more consistent numbers.

Cassey

Update:  Ok, bumping the timing cycle from 4 seconds to 30 seconds absolutely leveled this out.  On my 6-core development VM, with a 5 second cycle, I was seeing the reported hashrate bounce between 0, 20s, 40s, 70s, 120s, then return to 0 and start the cycle again.  With a 30 second measurement cycle time, its holding steady between 72-78 hashes/sec, typically around 75.  Some variation is, of course, expected.

The next release will have this change.  I'll likely push a new wallet out tomorrow morning.

I've also changed the debug.log message to report hash/sec instead of khash/sec.

Cassey

does not seem to connect to anything...
can someone post a few nodes
thanks

Same here, wallet won't connect to network

it is always funny when a coin announce that there is no need for addnode and you can't even connect to it...
What could be the reason ? Can this be related to the shitty hashrate ?

working fine,

Neat idea too, hope this works out in some fashion.

With how hard this is to mine value could/should be quite high.

can you post a few nodes
thanks

Sure I am just not familiar with the command that shows nodes, is it something I can do from the debug menu? Just let me know the commands I'll post the peer info here for everyone.

you can use "getpeerinfo"
thanks

Here, hope this helps anyone who had issues :)

RE:  Not connecting.

Very odd, we have 3 seed nodes that have never failed any of the development team, one of which was in that list.

The good news is that we have over 120 connections this morning on one of those seeds and the network hashrate is up about 15X over where it was 10 hours ago.  We are still running at minimum difficulty, but I'm seeing blocks tick by fairly quickly now, so we should be getting close to minimum mass.

Keep up the good work!

Cassey

ps. I have a remote node I'll add next time I visit the site as another seed - that should help diversify the network.  

Update:  Think we found it.  Our seednodes were using the default maxconnections of 125 and apparently maxed out.  They have been changed to accept up to 1024 connections now.

Watching this one, I like the idea of making it wallet only and tough to mine. May add this one soon.

Good choice! :-)

The dev team have already shown they are committed to providing long-term support for their coins and it's a refreshing change to see a coin like this. Reminds me of mining BTC on a CPU back in "the day".

cudaminer --algo=scrypt:131072  -lt5x7 -L6 (for a 750ti, need autotune for the other)

I would guess you would need the next step down on cudaminer.  Are you having success with that setting?  e.g. finding blocks?

http://puu.sh/bmzQw/2ef0e85e8b.png

For those just wanting to test a wallet, I'm happy to announce the -testnet functionality has been restored.  You may need to cold sync if you have previously used -testnet.

Github is current now, Windows wallet is being uploaded as I type.

Cheers,

Cassey

yes, I wouldn't post something which wouldn't work...
I tried first 2^16 but got only rejected, and I only get accepted blocks with 2^17 which is kind of strange I admit...

From the wallet code:

scrypt.h:static const unsigned long int SCRATCHPAD_SIZE = ((1 << (Nfactor + 1)) * 128 ) + 63;

Wondering if that +63 is biting you?  e.g.  your need 2^16+63?

Purely an intellectual pursuit, just curious...  Happy you found a GPU miner that works!

I'm looking on MediaFire that is hosting the wallet and its been downloaded 277 times.

http://www.mediafire.com/download/1vzyh5h0dg5bljh/imacredit-qt.exe

Please try that link directly.  Just  wondering if I garbled it on the website... Nope, download works for me.  Odd.

ok I will give it a try (cant' guarantee the result, I don't know very well cudaminer)

Thanks for testing.  Let us know and I'll tweet the results!

Unfortunately, most of my GPUs are AMD, not NVidia.  Need to go catch up on cudaminer, its been awhile.

Which version of CudaMiner are you using?  I'm getting an odd error:

user/password/rpcallowip are all set in imacredit.conf and the windows wallet is up and running on the machine.

Any thoughts? 

did you also add "server=1"?

I am running cudaminer 2014-4-12, not sure the link for it as I am at work.

Everything is running fine for me and have found 7 blocks so far.

Edit: I figured like above poster you already had the

server=1
listen=1
daemon=1
rpcport=???

It doesn't work... got validation problem on the cpu (meaning that what is calculated on the GPU is different from the sanity check performed on the cpu using the same nonce)
Actually, This code was also working on Aiden (Nfactor=6 with 2^6... so that's really strange)

OK, helps if I use "rpcpassword" instead of "rpcpass"... needed the "server=1" too.

So now its running, decimating anything I try to do on the windows box, but also seeing the CPU validation error.

Off to try and see if I need to set anything special for a GTX 560 Ti.  I'm noticing two messages that are probably relevant:

[2014-09-05 14:40:36] GPU #0: GeForce GTX 560 Ti with compute capability 2.0
[2014-09-05 14:40:36] GPU #0: the 't' kernel requires 3.5 capability!

Hit the web and sure enough, apparently the 560s are too old.

What hashrate are you seeing using the GPUs?

Cassey

the "t" kernel if for titan, ie for compute 3.5.
Try the fermi kernels "f" or "F", they should work on your card

Yes!  That did the trick.

Seeing a hashrate of about 0.03 khash/s, e.g. 30 hashs/sec - virtually identical to my quad-core CPU - as expected.

Nice to see that validated.

Cassey

I am from China.could you please use mego.io?That works fine .

i get 0.26kh/s out of my gtx660 with k6x11 but no blocks where ever found after several hours...
at the same time, the cpu already found 4 blocks with pooler's cpuminer, getting an average of 0.25kh/s out of a i7-3770 (the wallet gives me at most 77h/s).

Ok so we are also testing at the moment. Hashrate displays are totally wrong (lowered to fractional diff for testing). If anyone wants to help out let me know

Nah, this coin would need value for that to happen.

Very cool.  Out of town for the weekend, but will player with cpuminer when I get back.  Can you share your startup string for cpuminer?

9.1.0 used the standard 4/sec hashrate window and jumped around a lot.  Suggest 9.1.1 or 9.1.2 (latest) which uses a 30/sec hashrate window.  Not perfect, but a LOT better.

Cassey

it's new wallet?

nothing fancy, just the algo selection: --algo=scrypt:131072

update: cudaminer works indeed, it just doesn't print out that the block was accepted (the "yay!!!"), i can tell because overnight cpuminer just found 5 blocks, but the wallet shows up 10 mined blocks, so i assume the other 5 were mined by the gpu...

All great news.  It was my hope that GPUs would perform at about the same rate as CPUs.  Perhaps 5-10X faster, but not 200X like on Scrypt.  Seems we are close.

This, of course, leads us to the question of which is more efficient, both in terms of $/hash and Watts/hash.  My guess is those are pretty close as well.

Cassey

gpu are not efficient in the sense they are bottlenecked and run at only 50%tdp (hence they practically don't consume anything).
But the problem is I am not sure it make much sense to run a gpu on that coin altogether which leave the coin entirely to botnet and aws, which I don't think is a good idea (but that's my opinion...)

Regarding block being not reported in cudaminer, you need to use -q to remove all the hashrate info, this way you will see the "yay" when a block is found (haven't had any problem at that level)

nope, all output was redirected to a file and there wasn't any yay... however i've also restarted cudaminer with the -q about 4 hours ago and the gpu found a block but nothing new was printed:

cassey, was the launch of this coin even promoted? judging from from current network rate (~8kh/s) 4 days after launch, seems that just 4 cats are mining it...
i never thought i would ever mine with 1/16 of total net hash power with a common desktop  :o

are you sure it is your gpu ? Mine reported every blocks it found (I can't say precisely it was my gtx660, as I was running a 780ti a 750ti and the 660 at the same time.

well, my cpu wasn't as i know for sure i get the yay from cpuminer:
and the wallet runs with gen=0, so if it wasn't cudaminer, the holy ghost should be the culprit  ;D

edit: found another block right now and no output from either miner...

I've found a few blocks, but what do I do now? Are you pushing towards any exchanges or is it going to take a while? Is there anyone here that would like to buy some IMACredit from me?

We are in discussions with C-Cex and Poloniex right now.  One advantage of being an established developer is that both exchanges currently list one or more of my other coins.  With a bit of luck, we should be up on one or both in a week or two.  Maybe.  Can't promise something I don't control.

Then I'll keep mining! Thanks!

the only problem is it will be like primecoin and mined by botnets and the dudes that run the IT departments at wells fargo and shit, just can't win. if we could just have an asic company that sold shit now and for a reasonable price or some gpu coins that would hold their value against this shitcoin scam infested mess we have now everything would be cool. greedy cocksuckers are the number one problem we have, not algos. but if you can find a way to defeat the scumbags i'm in for sure.

Should I encode a world peace algo as well?  With complete freedom and prosperity for all, no government controls, and everyone will be nice to everyone and never take advantage of the gullible.  Everyone would, of course, WANT to work full time jobs and will happily do so whether that is flipping burgers or doing robotic design, because that will be the right thing to do for society.  We can build home that will last 1000 years, out of rock, so there won't need to be fire department, and safety will be improved.  Very sustainable.

Short form:  Have a real suggestion?

Anybody have a link to a Windows 2.4 version with scrypt:131072 support in it?

I have it running on about 7 Linux boxes just fine, but the 2.4 Windows version from Sourceforge generates:

minerd: unknown algorithm -- 'scrypt:131072'

For reference:

minerd -V
cpuminer 2.4
 built on May 20 2014
 features: x86_64 SSE2 AVX AVX2 XOP
libcurl/7.34.0 zlib/1.2.8

very nice! but how nvidia to work?

set worker=<rpcusername>
set pass=<rpcpassword>
set opts=--algo=scrypt:131072 -lf5x7 -L6
set url1=http://127.0.0.1:9332
set s1=-o %url1% -O %worker%:%pass%

cd x64

cudaminer %opts% %s1%

Works fine on older NVidia.  Use -lt5x7 for Titan class NVidia.

scrypt(N, 1, 1) support was added on may 25, i can't tell if there is a windows build somewhere, but there are building instructions on github (https://github.com/pooler/cpuminer).

is this coin in any exchange?

Yeah, I made one pass using my coin developer box where I build the Windows wallets, but the MinGW environment isn't quite right for building minerd and I would hate to screw it up and break things.  Took me several months of playing to get it working for coin building...

Not yet, but its being discussed with Poloniex and C-Cex.

sorry, can't help you there as i'm windows free since year 2000, but you can gently ask cbuchner1 on this thread (https://bitcointalk.org/index.php?topic=167229.0) for an updated windows build...

Ah, sorry, was looking for a CPUMiner (aka. Minerd) current windows build, not a Cudaminer build.  Have that and its working fine against my NVidia card.

Less and less people mining?

Yeah, we lost somebody.  We need about 5K to reach critical mass.

Remember that you can't measure that hashrate vs. any other coin, at least not unless they are also N=16.

Good news, it looks like we will have a pool or two within a few days for those that want less variance.  Maximum mining results will still occur only if you solo mine, since the pool will have some overhead.

Still talking with Poloniex and C-Cex as well. 

Cassey

:) keep mining every day
 Have something want to know 
can ATI Card like 7850 mined S-N-16？（sphminer or sgminer or djm sgminer）

We haven't found a GPU miner yet that can handle that N.  Most appear to allocate the hash scratchpad from the stack instead of the heap and die with stack overflows.  Good news: that is fairly easily fixed by the code writers if they wish to do so.  Bad news:  we are waiting for it to happen for some someone to find a branch that works.

When they do, I'll post, since I have half a dozen GPUs I'd like to point at it.

Good time to point out that midrange GPUs are hashing at, ballpark, the same speed as CPUs.  e.g.  My GTX 560 Ti is doing about 90hashes/sec which straddles various CPUs I have running (40-120 hashes/sec).

Cassey

Probably a good idea to get a roadmap/promotion going.

Thank you C-Cex!!!

i will give this a go, how long would u expect till i see my first block

If variance is a concern, we should have a pool up soon (e.g. tonight?  maybe... a day or three is more likely).

Otherwise is the standard luck-of-the-draw, but I tell people to think in terms of blocks per week vs. per minute.  E.g.  Let it run for a few days and see.

Cassey

92 billion coins

4.3 minute blocks

.......

Why even bother ?.

GPU mining ??

There's no gpu mining (yet and probably long time) and based on my personal experience we won't see 92 billion coins until about 300 years. Just mine with the wallet as it states in the OP and come back in a week you may have 40-150 coins. This is high coin count with mega slow distribution. In other words no miner dumps and cpu only.

Just do the math.  256 seconds per block * 16 coins/block = ~2M coins a year.  Are you really concerned about coins found 46,640 years from now?  If not, there are 2M coins available over the next 12 months - go get some.

Looks Hash is less than you GTX560
 ;)G1620    1 thread=10H/S

Well, good news and bad news.

Good news:  Your GTX is doing fine.

Bad news:  after an evening or three of testing, we can confirm that --algo=scrypt:131072 is required, although we have no idea why.  That should be the parameter for a N-17 coin.  If you use scrypt:65536 (which is what we expected) the miner will hash, but all blocks were rejected.  This was previously reported and is now confirmed.  Alas, that is what I was using with Cudaminer in my previous reports so my 560Ti numbers were double what they should have been.

Our best guess is that there is an additional 63 byte wrapper associated with the scratchpad space, meaning scrypt:65599 might work, if the code accepted that value, which it doesn't...

Oh well, at least it keeps it going at a nice, slow... but steady pace. ;-)

Here it the N expression:
https://github.com/IMAcredit/imacredit/blob/master/src/scrypt.cpp#L261

So nfactor is 16 -> n = 1 << (16 + 1) = 2 ^ 17 = 131072

Other values are not good.

----------------------------


After 2 days, my balance is zero.

"hashespersec" : 10,

"timeoffset" : -5,

What should I do?

change cpu
or
use GPU

Is there a way I can setup my Gridseed miner to mine this and use my computer's on-board RAM?

any pools yet?

I'm testing on my pool for a day. it works:
http://coinspool.cu.cc/

You need the latest cpuminer (https://github.com/pooler/cpuminer):

Doesn't look like your pool is finding any blocks though. Are those hash measurements correct?

Actually, that makes 3-4 pools.

There is also http://mpos.imacredit.org and http://www.multicoinpool.org.  Stratum ports on the website (http://www.imacredit.org/coin-details.html (http://www.imacredit.org/coin-details.html))

FYI - most pool software really sucks are reporting low hashrates that are the nature of IMA Credit.  One of the devs is going to try and get mpos.imacredit.org reporting in Hash instead of KHash later today.  Wish him luck!

I believe HashHarder also spun up a pool, but don't know much about that one.

Cassey

80-90 blocks have been found with 240 hash/sec, cpuminer report:

Those rates seem right on.  I have a number of machines that vary from 0.01kh to 0.08kh.

Having one of the dev's modifiy mpos.imacredit.org to report things in hash instead of k-hash.  Will then start doing some testing around improving a motherboards performance by using dual memory instead of single, using a GPU instead of the onboard CPU based graphics (which shares memory with the CPU).

Will post when I get some results.  Just thinking this might be the perfect excuse to buy some micro-ATX boards and hang them off my ASIC power supplies that are not using the motherboard power cables...

Cassey

yes pools maybe should display hash in h/s  not kh/s  ;D

{
"blocks" : 3690,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.00078303,

"generate" : true,
"genproclimit" : -1,
"hashespersec" : 0,
"networkhashps" : 15318,
"pooledtx" : 0,
"testnet" : false
}

Which looks quite heathly - about 3X the minimum hashrate to insure target block times.

A bit of good news:  one of the developers modified http://mpos.imacredit.org to display in Hash instead of KHash.  Now you can track what your miners are really doing...

Please do spread the load between pools if your not inclined to solo mine (preferred).  The pool is up mostly so people can verify they are working, we are fine with temporary visitors.

Cassey

can somebody share his/hers settings how to mine over pools,i try everything from cgminer to vertminer,i think i tried 150 miners,but cant put it on work,i have amd fx-6300 cpu and sapphire r9 280x toxic cards...anyone...Cassey....!?
ps..you can even put it like riddle,i think i would faster make it work then this:))...btw,windows 8.1 i have..thx

You are currently limited to mining with the wallet given your configuration.

Under windows, CUDA miner works, and under Linux both CUDA and Pooler's CPUminer (aka. minerd) work just fine.  Alas, CUDA is only relevant if you have a NVidia GPU.

I'm continuing to try and find a Windows version of CPUminer that will accept the scrypt:n parameter, but have not found one yet.  I'm trying to build on from the github repository, but building under windows is proving challenging.

Other miners like sgminer can not handle N=16 due, I believe, to their allocation of scratchpad space from the stack instead of the heap.  They seem to break on any N > 14.

Cassey

ok,thx Cassey..i guess will continue mining with wallet,good luck finding something for windows ,if not we will Better Call Saul;)

But be shy about continuing your quest and posting success here!  Surely somebody has a CPUminer compiled for Windows that came from the current github tree?

I'm using the yescrypt miner and it's working so far... From GlobalBoost-Y (BSTY)

https://mega.co.nz/#!2Q9AyJbT!2fLnh_5JKzXp_gGGW9_6uoEDvAERYAoPe2npeCK4OZc

Copy and make bat file: minerd -a scrypt:131072 -o stratum+tcp://mpos.imacredit.org:10052 -u youruser.miner -p x

Win7 64 with i7 4770k ~ 0.25khash/s adding -t 4 I got ~ 0.15khash/s (Dunno Why)

Win7 64 with FX6300 ~ 0.09khash/s but adding -t 3 I got 0.26khash/s (Not stable, sometimes go down to 0.06khas/s)

Hope it Helps

Thank you!

thx D.R.O.I

any idea why I get halve the hash while solo-mining to the wallet in comparison to the pool?
I use cudaminer, mining against the wallet.

solomining (self compiled linux wallet):

casseys pool:

...when I start solomining the first round shows the higher hash... but slowsdown right after.


EDIT:
found out that my usual solomining -s 1 switch (upper bound on time spent scanning current work when long polling is unavailable, in seconds) makes trouble.


EDIT2:
getting some json call failed from time to time... often after founding a block.
similar to the first jackpotcoin wallet releases...

would support this nice coin with a small raspberry (raspbian/debian) node.
but get some ugly failures while compiling that I get not on my usual (ubuntu 14.x) node.

You are missing libdb.

I don't have a pi running right now to look but thats where you need to start.

This coin seems very interesting.
Will look..

thanks for pointing me on the right direction. had to install db4.8 manually.
now compiling goes further... but stops here:

Thats saying your hardware does not support msse2. You can take that out of the .pro or makefile.unix but you might want to ask cassey about if it is required for the client or not.

Nothing update

I thought so... the pi has no SSE2. Maybe it's just for mining in the wallet and not nescessary for the imacreditd daemon.
Hope Cassey will give some answer about this. I just deleted this part in the makefile.unix and the compile finished without any other errors.
Everything takes forever on the pi... the network sync too  ;)


question:
cassey's pool: 1,928.717 H/s
"networkhashps" : 10974 (H/s?)

...are those numbers right?
the nethash is 10.9 Khash at the moment?

no win miner on the OP  :( :(

the wallet works... and here is some other point to start:

lol no the pi has no SSE2 and you are probably right that it wont affect anything. I've taken that out on a couple of wallets for pi building and can't say its ever been an issue.

Hey dev any news or updates on IMAC?
 

dev,have no news?

...sad - this coin was a nice concept.

was nice buying on https://c-cex.com/?p=imac-btc the last 10hours...
imacredit were bought up to 0.00006300 sat

as this coin already seems as good as dead, i've created an appeal for economy absorption:
http://coinshieldtalk.org/forum/coin-shield-talk/shitcoin-petitions/348-imacredit-coin
(sorry i forgot to create a poll on the petition, the site admin will add it in a few days for you to vote, meanwhile please post your arguments, thank you)

someone tell me where we will be able to change now that c-cex.com's going to take the 30th of this month

I'd say nowhere..
though keep an eye on 1billionhex.com as IMAC coin is set to be a part of the crypto void game sometime in the future.

is this coin delisted from ccex ???

all you had to do was go to c-cex, the answer is no its not delisted. it is still there open for trading. 1100 satoshi buy side, 1800 satoshi sell side.

i guess we have to buy more coin

https://c-cex.com/?p=imac-btc

delisted... game over... >:(

their is a movement on poloniex calling for the coin, about 5-6 of us have already submitted applications to have Imac added to polo

if you wish to see the coin progress people here could also fill in the form

the more requests they get the more chance it will be listed .

https://poloniex.com/coinRequest (https://poloniex.com/coinRequest)

Q

Submitted

I have also submited to Polo coin request.

good luck to us all :)

I'd say it will pick up traction and be listed somewhere once 1billionhex's "The Crypto Void" game development gets more notice. but who knows. good chance at this time to get coins if you've got some spare cpu cycles.

Is development still happening for this coin?

Is this coin live or dead?


I've been mining for some time now but no exchange is accepting it.

I'm considering stopping.

Any dev - Anyone?

I decided to fire up my wallet tonight and start mining, I made my own wallet some tme ago with upnp support although i only have one connection so far.   I like some of the ideas behind this coin.  The developers are certainly competent.  I doubt they have abandoned the coin since this and others were designed for a large scale project......

Going to try pooler once i get the blockchain up to date.

To those who are upset about exchanges and such consider why you want to mine a coin if all your plans are is to just exchange it for another.....   I realize most will not mine coins not listed on exchanges. A sad reality of the people who haunt these forums.

I've forgot about my miner for this, still hodling, still mining.

Some sort of response from the devs would be nice :S

From my little experience on CryptoWorld, dev of this coin ( 1BillionHex on this point) seems trying different logic experimenting with different coin. He develop more then 3 coin and those are still live. Every coin has their own pro and cons like:

1Credit having low block rewards with long block time,
YACC having low difficulty with lots of rewards on block etc etc.
where
IMACredit having fare rewards, fare block time, fare algorithm attached to prevent ASIC's. 

On IMACredit it seems dev wanted to show a different approach of showing negligence and might all of sudden came with some kind of announcement which might worth mining. Unless delisting from some exchange I didn't find any negative on this coin. I still mining it with good block rate. Who knows, one day I may lough on people calling this project 'Dead' ?? Unless I find less then 0 connection on wallet or no transaction in 7 days in network, I will continue mining this.

Some time patience do work!

Isn't it good idea to have 'mining on low difficulty' then 'pre-mining' lots of coin before released ??

People giving up with mining IMACredit can dispose your coin to my address:

Who knows one day I might return you some bits ;))

None of this is true, except coin specs listed. Cassey is the dev not bill. 1Billion Hex is using this and 3 other coins as part of a game he is developing where IMAC, YACC, 1CR, & an unlaunched coin will be used as in game tokens to say unlock items or derive names etc etc.
theres some info about thecryptovoid which is 1billionhex's in progress game at 1billionhex.net

Cool, atleast we got some Info in return of my 'Guess' post. Can we know the reason behind IMAC's inactivity specially in Marketing, Exchange Listings, New Information/update. We wander what makes this IMAC soo ignored people even start calling it as a 'Dead Project' ? Perhaps it's name, the initials conflicts with some other BIG Profile Customer Product??

I´m also mining it, while is at really low dificulty (even lower of dificult minimun). I´m sure that with a some marketing movements, this coin will have value in the future... but perhaps it´s no the moment.

Another miner here :) also supporting network with running wallets on 3 different ip addresses.

if anyone wanna get rid of coins, i'll be happy to collect them. here's address: 98SQU4y24f5doqZ1WSUkVqNY66mnqm53zB

I might even be persuaded to buy them. send me a PM.

GO IMAC!

Could you give me any IP adrress for my wallet sync. THKS

Seems nobody want to give sync IP of wallet in case other minars share on block rewards;)

Here is my one: 104.194.247.235 . Sync & enjoy.

Keep mining IMAC and you IMAC..go go

Anything new?

Nothing till now..don't know if we should stop mining :(

Regarding those seeking nodes or connections, the last time I communicated with the lead dev. of this project he confirmed that he maintains several nodes hard coded in the client and his official wallets have no option for UPnP. 

For myself I just slightly modified the .pro file and built myself a wallet with UPnP to use.

Still I would not disrespect the developers of this project releasing a binary of that build. 

I am just stating my preference is to have more connections when mining/ using a system.

I feel the more nodes someone can connect to the better.

There are others who feel differently and for good reasons of their own.

--- for those looking for something new --- I suggest being patient or contact the dev. in their official forum.

If a coins blockchain is moving and you can connect to the network when you start up the client and stay connected it functions.....

Hello

I 4920.69751472 IMAC

Want to buy ?

Thank you

Maybe, just maybe, might have a project that will use IMACredit as its base.  Should know more in the next week or two.  Until then, I'm working on making sure all the seed nodes are stable and current, and doing a bit of mining.  ps.  mpos.imacredit.org is back online if anyone insist on pool mining.  Recommend tpruvot's miner for those that don't want to solo mine:

nice -n 19 ./cpuminer --algo=scrypt:131072 --url=stratum+tcp://10.184.155.39:10052 --userpass=Cassey.rackserv:pass --quiet

If this take off, it won't be anything quick and not likely public for some time.

Basically the new project developers are looking for an ASIC resistant coin with a bit of history and an established blockchain that they can partner with.  Could be great news, likely will become nothing.  Still, thought I'd mention it, even though the coin currently has no exchange that I'm aware of.

Cautiously optomistic with the new development.  Suspect it will be 3-6 months before any code is made public, but I've been made part of the development team.

If in that time frame, significant progress is made, I'll likely refresh IMACredit off the current Vertcoin stream, retro fitting the significant changes that made IMACredit unique, while preserving the current blockchain.  That will bring the code base up to snuff with features like WebSockets, which will industrialize the coin a bit.

I've refocused a number of my systems to mine IMACredit with blocks coming out close to the expected time.  Suspect we are only a few big machines, or a few dozen small ones, from have a steady flow of blocks at the target interval.

As always, the best thing to do is to solo-mine the coin, but http://mpos.imacredit.org has been up and running steadly since this new initiative started.

Not pumping the coin, especially since there is no exchange handling it, but trying to be as public as I can about whats happening.

wow, that's great news. i haven't mined now for a year or so.  :'( but i've synced wallet without a hitch and  i'm puting some miners to work later today.

also, is there any blockexplorer working? or is there some code, i might be able to host one.

Thanks.  Unfortunately none that I'm aware of - those tend to appear in sync with exchanges.

Just a little bit of news:  I know the developers have successfully interfaced their code with the wallet, which isn't quite as easy as it sounds, since every well baked coin has their own "magic number" and similar changes.  For instance, its pretty trivial to figure out what the current block number is, that is just an RPC call, but doing transactions or validating addresses is just a bit harder.

Lots of room for improvement on how they are doing it, although their current approach isn't bad.  I MIGHT have to refresh the code to enable a more efficient interface, but that should become obvious over the next couple of months.  If so, it will be transparent and not require any forking.

I have a little desktop "appliance" class box that is doing pretty well.  Its a $250 quad-core celeron with 4gb of memory running linux and its mined over 800 coins since I cranked it up when this new project started.  That is competing with a 56 core Xeon I'm using to keep blocks flowing.  Point being, everyday home machine have a reasonable chance at finding blocks - just measure success in coins/week, not coins/minute.

If you (or anyone else) does host a block explorer, please let me know.  I'll update the official webpage to point at it.  That would be a great help, since most exchanges require one to be functional.

Just a quick update:  Progress on the new project is continuing.  The next step is a big one - validation of their key algorithm.  Most of the basic window dressing is complete.  The next few weeks will be interesting.

Regarding  IMACredit, I could use a hand with a couple of things:

1)  Need a blockexplorer
2)  Would like to revamp the website and possibly move it off of Weebly (mostly since Weebly wants an arm and a leg and part of my other arm to provide https support, which is kind of basic these days now that letsencrypt.org is available).  Since the project is written in GoLang, I thought Hugo would be cute.  I can provide the VM, certificates, etc. but could really use some help.
3)  Going to spend some time and work on being able to rebuild the Windows GUI.  Most of the original packages have updates, and alas they didn't all play together well on my previous attempt - so will try again.

Last but not least, may end up resetting mpos.imacredit.org.  I appear to be the only user, and this might lighten the load for the maintainer of that site.  Its currently suffering from a mysql database issue (duplicate payment of a block type thing).  I'm open to using newer pool software if anyone has a suggestion for something that is currently ACTIVELY supported.

Good news is the coin blockchain appears to be nicely stable.

Cheers!

ps.  If you happen to want to work on the main project, and are comfortable coding in Go, please let me know.  The project is all volunteer based and not currently paying anything, but still, could be fun.  I'm doing what I can...

Hey,

About blockexplorer. i've been poking around wallet and rpc commands to get out data for blockexplorer. I can get data for blocks, but I didn't figure out yet, how to build data about transaction :/ thou, I didn't spend much time on that. I'll try to lookup my transaction history, and figure it out from there.

guess I could build BE without tx data (just tx ids in block) pretty fast. If time is issue and no tx data is required, I could get things up and running by end of the week. Otherwise, i'll try to figure all out and build a proper BE. Let me know.

best regards

Time is NOT an issue.  This project is being measured in months, not days.

Spent the last few evenings recreating a build environment for the Windows version of the coin, finding capable packages, etc.  Did upgrade to 64-bit.

Having one problem with the new code and wondering if this rings a familiar bell with anyone:

The new executable claims the old wallet is corrupt.  It works fine is allowed to create a new wallet, and the old wallet works fine with the old executable.  Tried 32 & 64 bit versions.  Tried db5.3 as well as the original db4.8 - no difference.

Not really interested in moving all my private keys, would rather figure out whats wrong.

I DO NOT have this problem with the Linux version, the code was completely compatible there.

This isn't hyper critical, but would be nice to get fixed.  Other than going to 64-bit mode, the only other change is additional checkpoint records and a bump in the protocol (which I used to track adoption of wallet packages).

A new windows wallet was published today.  It has the latest checkpoint information and new artwork (some may recognize the heavy influence of my defunct coin, YACCoin).

You can grab it off the link at http://www.imacredit.com. 

PLEASE keep a copy of your original executable.  Testing here at my remote site showed no problems, but previous efforts at another site generated an executable that wasn't compatible with the old wallet (for totally unclear reasons).  If you get a "non-recoverable wallet" type error seconds after launching, just revert to your old code, and PLEASE post here.  In fact, if you don't have any issues, PLEASE post that here as well!  I'll be testing this executable when I visit my other site next week.

Slightly tweaked http://ww.imacredit.com as well, and snuck in the name of the new project that is using IMAC...

I've been syncing a number of new machines, would not expect you to have any problems.

How large of a bounty would you want?  Perhaps PM me and we can negotiate <smile>.

GoArchit (www.goarchit.online) is at 50% complete, next step will take it to 60% expected in the next couple of weeks.

Thanks!  Let me know when the block explorer is up and running.  Note that IMAC is a n-script coin with a large enough n that most generic code needs tweaks to work (mostly just changing stack memory allocations to heap allocations)

Any news about this coin?

hi guys is there any new update information about this project,its already april and no new post yet available here

No discovery. The developer has not managed threads for months, and without knowing what the situation is, the project is at a standstill.
