[ANN] Slimcoin : Proof of Burn NEW BLOCK GEN, Mineable by low power computer!

[KaTXi]

Sorry, we're getting DDoS'ed. I have to shut down the pool for now to prevent getting null routed. :/
Anyway I'm waiting on some nice servers that I ordered, which will have proper mitigation against these type of attacks.

May I ask how you got dcrypt into NOMP? Did you merge the dcrypt parts of cminer fork into node-multi-hashing ? Any plans to push the changes to the repo?

In case somebody is interested I've just compiled the miner from https://github.com/siklon/slimminer for windows with example how to use with the pool http://77.237.251.163

Thankyou so much i'll try this when i get home
If it works as im sure it will i'll send you 5SLM drop me a pm with your addy

That's a shame.  It's that or the CloudFlare route, I guess.  Good luck

At least it was up and running for a bit

Might want to hold off on that until the pool is back up - it's currently down ( see 2 posts above yours )

Stopped at blocks 4258 for a long time,Why???

Looks like the network hashrate dropped significantly, but the difficulty is still high.

hah, I don't know how well it would run on an Android - just compiling against ARM probably means forking one of the Android bitcoin miners, first

Lol I have linux on my android & ive been trying to get it to work /:

[2014-06-02 15:19:33] accepted: 0/2 (0.00%), 1.66 khash/s (booooo)

I guess that means they were orphans?

Tried mining in your temporary pool for a while sandor111 and it seemed to be working OK.  

Here's how windows users can compile a more optimized / cpu specific build of slimminer for the main pool when its back up.

1 - Download and run Cygwin installer: http://cygwin.com/install.html > 'Cygwin Setup' folder on C:

2 - Ensure that you add the following extra packages to the 'default' install from the menu settings window (a few tabs into the install process);

devel / gcc-g++

libs / libcurl-devel

devel / automake

devel / make

archive / unzip

net (web) / wget

devel / git

net (web) / openSSL-devel

Remember to add: "automake: Wrapper scripts for automake and aclocal" - along with the latest auto make release - or slimminer won't compile.

3. Start the Cygwin terminal from the desktop shortcut you created at install. Now copy and paste the following:

Code:

git clone https://github.com/siklon/slimminer

Code:

cd slimminer

Code:

chmod +x autogen.sh

Code:

./autogen.sh

Code:

CFLAGS="-O3 -march=native" ./configure

Code:

make

Check for errors during the process, however your minerd.exe (slimminer) should now be built in;

C: > cygwin64 > home > 'account name' > slimminer

4. You can start mining from the Cygwin Terminal. Ensure that you cd into slimminer dir after starting the terminal window with;

cd slimminer

./minerd.exe -a dcrypt -o stratum+tcp://POOLADDRESS:POOLPORT -u YOURWALLET -p x

Remember to set the correct pool address, port and your own wallet address. You can also add -t 'number of cores'.

--scantime 15 (is probably optimal for pool mining) and --retries -1 will try to resubmit shares if the connection drops.  

...

To get an optimized build of slimminer for your chipset you need to change -march=native before compiling slimminer.

For an i7 :

Code:

CFLAGS="-O3 -march=corei7" ./configure

Those values can be found at: http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86-64-Options.html#i386-and-x86-64-Options

Just delete everything in the slimminer folder if you want to recompile whilst trying to find the fastest CFLAGS for your chipset.

N.B. your miner will be dependent on your cygwin environment and is therefore not a standalone miner, but it will be optimized for your chipset and should certainly be much faster. You can also compile a working 32bit slimminer on windows this way.

Good Luck.

Please stop PM'ing me about the pool, I know it's down, I'm going to have the new server up pretty soon.

Can cloudflare prevent ddos attacks on pool?

[primer-]

    "difficulty" : 0.01352948,

Solo mining possible again.

Someone probably killed off 500+ Amazon instances. We are going to stay stuck on block 4258 for some time..

Not really, cloudflare filters http/s protocol only.

[TheRealSteve]

Not really, cloudflare filters http/s protocol only.

You mean the actual pool was being DDoS'd?  If so, was it intentional or just an influx of people connecting and the machine not keeping up? (as unlikely as that seems...)

I dont know but i seriously doubt it was a DDoS. Most likely influx of people, i myself had 30 servers connected in a couple of seconds. Maybe that triggered some kind of an alert at the provider that flagged it as DDoS.

We are frozen at block 4258. POW blocks are not accepted by wallet/daemon due to low difficulty(?). There is an actual check in the code.

  if(bnTarget <= 0 || bnTarget > bnProofOfWorkLimit)                                                                                                                                           
    return error("CheckProofOfWork() : nBits below minimum work");

It looks like we need a hard fork. DEV, look at the problem ASAP.

I think its the difficulty retargeting that is causing slow blocks, lets give it couple more minutes.

EDIT: Still on 4258. Not good.

We have a real problem with the coin. Just look at your debug.log. Mine is full of new POW block founds that are rejected due to the check below in main.cpp.

  if(bnTarget <= 0 || bnTarget > bnProofOfWorkLimit)

I am not surprised. The DEV is a fucking tard.

thats just one line in the miner (missing? / modified?).

read the source, even when you mine bitcoin now and remove the pre-diff-checl from the miner source part you'll have shitloads of this in your debug.log
