IRC:
Code:
start i2p
server: 127.0.0.1
port: 6668
channel #exchange

That server is loopback adapter... O.o Whats the point?

because you connect trough a I2P tunnel, you need to use the tcp proxy built into the i2p client. this client, of course, runs on localhost.

vircurex.com also trades ANC and you have to inform them about the wallet upgrade. I have been trading lots of ANC over there and so far I have not had any problems with deposits or withdrawals

Only vircurex to go... They're slow, let's see if they update or drop ANC

vircurex is run by the known scammer kumala, AVOID or lose your coins.

BTW (and sorry for being slightly off-topic): did blockchain.info remove "shared coin", their coinjoin implementation? Cannot find it anymore!

does not exist anymore Sad

That really sucks.
Just use joinmarket.

Ethereum doesn't use the same format.  The addresses are in hexadecimal and would need to be converted to ASCII to  see any words.

I guess there a few words you can spell with hex:  cafe, babe, abba.  There must be others.

besides that sending back and creating 1 UTXO dosnt not help, as i already did mention.

I thought that consolidating to 1 UTXO should help, but you say it doesn't. Have you tried any other bug-hunting ideas like creating a new wallet, and sending the coins to it, to compare?

I know you're an early adopter of EMC and you run the first emc explorer. So I think your opinion matters. If we can discover the problem then I am sure the devs will take notice and fix it.

Yes, that definitely helps. But a wallet with lots of old (spent!) txs will always have the problem.

you only need more RAM if your on winblows. their mapping SysRAM with GPURAM.

Yes I'm on Windows.
Is there any upper limit on the amount of RAM it will take?
Or will it eventually work it's way through 16 GB and crash again?
Thanks,
Dave
Im sure you'll use the 64bit version, so you wont hit a limit. Unless there are hidden winblows nasties, of course Wink

has there been a resolution to the

Code:
Match idx: 0
CPU hash: 93b30d0ad99f8133a0bc3c4793a27dbad5a0961f
GPU hash: 0a0db39333819fd9473cbca0ba7da2931f96a0d5
Found delta: 1919 Start delta: 1

issue? i'm running into the error trying to generate a simple vanity address and when using -V verification mode its much slower and i get the same error.

running recent (but not latest) catalyst drivers on AMD 79xx series cards on debian OS, all cards report the same error instead of privkeys.

mines every algo fine otherwise.
this has been discussed several times already, go back some pages or use the search function.

Minting on this coin is very cpu intensive due to bad implementation. The problem is mostly ignored and probably wont be fixed.

It is not true. Wallet feels fine even on old processors.

I find it works great staking on old processor too, even virtual machine. However I think there may be some problem if the amount of UTXO in the wallet is very large. Because, all those many amounts trying to stake separately...

The code for staking is at https://github.com/EvgenijM86/emercoin/blob/master/src/wallet.cpp in function CreateCoinStake. But I don't know enough about C++ to understand all implications.

Hopefully K1773R can explain more about his problem. And if there is a problem for some situations, then perhaps the team will investigate the cause.


yes, this is correct. with time your UXTO set gets big. even if your sending your coins back to yourself to consolidate, it wont help (ie having 1 UXTO). so the minting/stacking code is very bad.
Unfortunately this problem is ignored. may it be due to bad English skills or ignorance, it still an issue and others will hit it too.

In looking at it, I think there is nothing noticeably wrong with EMC's stake implementation. In the CreateCoinStake() of wallet.cpp there are conditions under which the stake will "split" or "combine" UTXO, depending on the amount of coins, etc. So if you have a large balance it may keep splitting until you have so many UTXO that it will begin to create server load (after many months). To remedy this you could send all coins back to yourself every few months of staking, to combine again into a single UTXO. This isn't unusual, I have needed to do this with other POS coins. Another option may be to tweak the split/combine thresholds in wallet.cpp and compile your own daemon that keeps the number of UTXO under control for your situation. Obviously you would need to be very careful about making such a change to the split & combine thresholds.

I am no expert in this just sharing what I see and perhaps there are better answers to your issue. I'm sure the EMC devs will agree that anything to improve EMC's useablility is worth discussion Smiley I don't think it is a widespread problem as smaller balances should combine properly but if it is a wider issue then hopefully someone can contribute an improvement to the staking code.
besides that sending back and creating 1 UTXO dosnt not help, as i already did mention.

Emerger, K1773R!

emercoind can load CPU if not found for more than two peers. From the number of transactions it is independent. Even with ~ 1,000 transactions on the simplest VPS ~ 2-3 CPU%
im sry but we are talking about something completely different.
71  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [EMC] EmerCoin — Innovative blockchain services! ( PoW&PoS - SHA-256) on: April 29, 2016, 07:28:45 AM
Do you have forum for technical issues? I dont want spam this thread too much with technical issues..

But, another questions:
Can I install emercoind on rasppi?
Can I mint on vps/rasp with emercoind?

More info. I added some RAM to the system and it kept going for almost 2 days before crashing.
I'm thinking something in one of the windows updates is causing some kind of memory leak in the program or the driver, but that is a guess at best.

I'll throw in another 4GB stick later in the week and try again.

-Dave

The computer doesn't need more Ram (all the work is being done on the GPU).  Have you updated your GPU's drivers?

OgNasty made a patch, search this thread for "LifeBoat"
That's the one I'm using.
I know system RAM should not matter, but @ 2 GB it will never make more then 18 hours. With 4 it makes it more then double that.

Latest NVIDIA drivers are installed.

-Dave

It's definitely something with system RAM
2 GB = 18 hrs before crash
4 GB = Almost 2 days before crash
8 GB = Over 3 1/2 days and still going....

However, I noticed that according to task manager it's not using that much memory. Very odd.

Also, dose anyone know the reason why it's using 50% CPU when all I have it doing is mining the the graphics card?

Does anything change if you increase swap-size? Memory leaks may be swapped away.
Alternative: take 2 GB ram and run oclvanitygen a few hours, then restart it. Repeat that and see if it crashes again.

Here it uses full CPU while mining on Nvidia. I assume it needs CPU to deal with the keys it finds or something. So the videocard just produces millions of keys per second, the CPU checks if they are the right keys. But I'm just guessing here Smiley

Edit: after reading shorena (see below) I am curious now what the CPU is doing Smiley
your guessing wrong Wink

This seems like such a scam, forgive me for saying so but how does anyone expect this to be transparent when its run by people who use the darknet?!!?
you'd be surprised but the I2P people which you refer to "darknet" can be trusted more than people on clearnet...

I forgot I have an account in Cryptostocks.com. This week, I realized that I have 15000 bits there, but cannot withdraw because the minimum amount is 20000 bits.
Is there a way to recover this money?
of course not, because the owner is a scammer... gosh, read!

Hey!

0.8.5.6 is newest wallet?
It looks pretty old, any ETA on new release?
No its not, get the current master.

Still no cryptonote?

All those fake anon coins and premined scamcoins. LOL

Remind me what this exchange is for again? Was it For anonymity?  And still no crytptonote?

I'm really disappointed and this is why I keep an eye on it through a proxy and have no need to run I2P.

And if any Scam Crytonotes are added before XMR (one of the few non scam ones and the obvious leader) you can damn well be sure you will never get any volume.

For those of you that don't know the B Y T E C O I N scam.
