[ANN][BLC] Blakecoin Blake-256 for GPU/FPGA With Merged Mined Pools Stable Net

[mogrith]

That is one drawback to merged mining. Solo or  reg pool you get BLC but merged you get BLC, PHO and soon more.

So fewer solo miners as everyone moves to pool. But at least with 2 merged pools it's not all in one pool.

That is one drawback to merged mining. Solo or  reg pool you get BLC but merged you get BLC, PHO and soon more.

So fewer solo miners as everyone moves to pool. But at least with 2 merged pools it's not all in one pool.

You can solo merge mine. I believe bzyzny is writing up some mining related info, if he doesn't include the merged setup info I will pass it along for inclusion.

EDIT: Or give the info here, now:

blakecoind setup

1) Obtain a compiled blakecoind.

2) Decide on a data directory location.

3) In this directory, create blakecoin.conf text file, with the following contents:

Code:

rpcuser=MY_RPC_USERNAME
rpcpassword=MY_RPC_PASSWORD
rpcport=8772
logtimestamps=1
listen=1
gen=0
rpcallowip=127.0.0.1
server=1
daemon=1
addnode=162.243.133.80
addnode=162.243.14.130
addnode=146.185.135.24
addnode=184.171.247.23

Obviously, change the MY_RPC_xxx to a username and password.

4) Create a newblock.sh script, with the following contents:

Code:

#!/bin/sh

killall -USR1 eloipool.py

Mark it executeable via "chmod 0755 newblock.sh"

5) Create a run-blakecoind.sh script, with the following contents:

Code:

#!/bin/sh

/pah/to/blakecoind \
	-datadir=/path/to/data -daemon \
	-blocknotify=/path/to/newblock.sh

Mark it executeable via "chmod 0755 run-blakecoind.sh"

You must modify the (a) blakecoind path, (b) -datadir path, and (c) -blocknotify path to fit your local computer.

6) Run blakecoind via the run-blakecoind.sh script.  Watch debug.log in the data directory, to make sure it started the Initial Block Download (blakecoin network sync).  This might take a few minutes, to download all the blocks.  


eloipool setup

1) Download eloipool dependencies, either from your Linux packager, or directly:

Python 3                        http://python.org
python-bitcoinrpc       https://github.com/jgarzik/python-bitcoinrpc
python-base58           https://gitorious.org/bitcoin/python-base58
midstate                        http://gitorious.org/midstate/midstate

2) For python-bitcoinrpc, check out an older release,

Code:

$ cd /repo/python-bitcoinrpc
$ git checkout -b solo-mining 770881c8bd9b1f92427290270b37a28751cf9df0

3) Check out eloipool,

Code:

$ git clone git://github.com/BlueDragon747/eloipool_Blakecoin.git

4) Copy config.py.example to config.py, and make the following several edits,

a) change ServerName to something unique

b) increase share target if desired (note increase '0' and decrease 'f'):

Code:

-ShareTarget = 0x00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffff
+ShareTarget = 0x00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffff

c) DynamicTargetting = 2

d) DynamicTargetGoal = 6

e) change TrackerAddr to YOUR blakecoin address

f) comment out CoinbaserCmd,

Code:

-CoinbaserCmd = 'echo -e "1\\n$((%d / 100))\\n1579aXhdwvKZEMrAKoCZhzGuqMa8EonuXU"'
+#CoinbaserCmd = 'echo -e "1\\n$((%d / 100))\\n1579aXhdwvKZEMrAKoCZhzGuqMa8EonuXU"'

g) update TemplateSources to point to your local blakecoind RPC, including chosen username/password, and comment out the secondary source:

Code:

@@ -57,41 +57,41 @@
 TemplateSources = (
        {
                'name': 'primary',
-               'uri': 'http://user:pass@localhost:8332',
+               'uri': 'http://MY_RPC_USERNAME:MY_RPC_PASSWORD@127.0.0.1:8772',
                'priority': 0,
                'weight': 1,
        },
-       {
-               'name': 'secondary',
-               'uri': 'http://user:pass@localhost:18332',
-               'priority': 1,
-               'weight': 1,
-       },
+#      {
+#              'name': 'secondary',
+#              'uri': 'http://user:pass@localhost:18332',
+#              'priority': 1,
+#              'weight': 1,
+#      },
 )

g) empty TemplateChecks (or comment out 100%),

Code:

 TemplateChecks = (
 )

h) comment out or delete BlockSubmissions

i) change log settings, and switch from testnet3 mining to mainnet:

Code:

-DelayLogForUpstream = False
+DelayLogForUpstream = True
 
 # Bitcoin p2p server for announcing blocks found
-UpstreamBitcoindNode = ('127.0.0.1', 18333)  # testnet
+UpstreamBitcoindNode = ('127.0.0.1', 8772)
 
 # Network ID for the primary blockchain
 # Other known network IDs can be found at:
 #     https://en.bitcoin.it/wiki/Protocol_specification#Message_structure
-UpstreamNetworkId = b'\xFA\xBF\xB5\xDA'  # testnet
+UpstreamNetworkId = b'\xF9\xBE\xB4\xD2'

j) update ShareLogging to reflect your desires.  The simplest is to delete all the SQL-related entries, leaving only the textfile logfile.  With solo mining, you don't care so much about shares. Optionally enable logging to a database here for use via an MPOS gui later.

Code:

ShareLogging = (
        {
                'type': 'logfile',
                'filename': 'share-logfile',
                'format': "{time} {Q(remoteHost)} {username} {YN(not(rejectReason))} {dash(YN(upstreamResult))} {dash(rejectReason)} {solution}\n",
        },
)

k) change log filename to something useful,

Code:

 LogFile = {
-       'filename': 'filename.log',
+       'filename': 'eloipool.log',

l) Create a runit.sh script for eloipool, with the contents,

Code:

#!/bin/sh

PYTHONPATH=/path/to/python-bitcoinrpc:/path/to/python-base58:/path/to/midstate \
     nohup ./eloipool.py 2>&1 >/dev/null &

You must change the paths to suit your local system.

m) Run eloipool with runit.sh script

n) Let's assume you are running the pool software on 192.168.1.40 IP address.  Set up your miner configuration like this:

Pool X: stratum+tcp://192.168.1.40:3334
Pool X username: anyuser
Pool X password: x

The above gets you a private Blakecoin mining pool.

The pool we created above only mines Blakecoins, to merged mine BLC and PHO:

Acquire a compiled photond, create a data dir and photon.conf in the same way you did for blakecoind.
Acquire merge-mine-proxy: https://gitorious.org/bitcoin/luke-jr-bitcoin/source/8f3f29550c2ad33f5635799ba835276eaebb4a2e:contrib/merged-mine-proxy

eloipool config.py

Code:

# Secret username allowed to use setworkaux
SecretUser = "ssecreteloipool"

GotWorkURI = "http://mergedproxyuser:mergedproxypass@127.0.0.1:8330/"

GotWorkTarget = 0x00000000000fffffffffffffffffffffffffffffffffffffffffffffffffffff #1024

photond config

Code:

rpcuser=photonrpc
rpcpassword=photonrpcpass
rpcport=9377
listen=1
gen=0
rpcallowip=127.0.0.1
port=35556
server=1

mining proxy command

Code:

python merged-mining-proxy  -w 8330 -p http://ssecreteloipool:222@127.0.0.1:8337/ -x http://photonrpc:photonrpcpass@localhost:9377/

Troubleshooting and optional info by BlueDragon747:

start blakecoin with block notify
start photon
wait for them to be in sync!

start eloi
within 3 secs start mmp
check log, wait for a share if you get a solve its working ignore errors

if you just get update aux and no solve for ages and you have decent amount of hashing or lowish gotworktarget repeat above
if you get stale merkle its fine should get a solve shortly
if you get bad merkle them it seems mmp is not connecting to eloi

In mmp I did tweak the -R rewrite to match the gotworktarget and it does run better than just leaving it out (edit at line 253 and 462 to match your gotworktarget) then just add the -R switch to you command e.g:

python merged-mine-proxy -w 8330 -p http://secretuser:123@127.0.0.1:8337/ -x http://photonrpcuser:rpcpass@localhost:9377/ -l mmp_log.txt -R >/dev/null

You *might* be able to merge mine without eloipool, using only the blake and photon coin daemons coupled with merge-mine-proxy, but I have not tried.


EDIT/UPDATE 5-15-2014:
Moar coinz!

The launch of B+ and impending launches of Dirac and AT brings the need for config changes.

Acquire a compiled B+, create a data dir and blakebitcoin.conf in the same way you did for the other coins.

Use this copy of merge-mine-proxy: https://github.com/BlueDragon747/eloipool_Blakecoin/blob/master/merged-mine-proxy.py

blakebitcoind config

Code:

rpcuser=blakebitrpcuser
rpcpassword=blakebitrpcpass
server=1
listen=1
maxconnections=180
rpctimeout=30
rpcallowip=127.0.0.1
addnode=146.185.135.24
addnode=162.243.14.130
addnode=188.226.213.85
addnode=107.170.140.27

mining proxy command

Code:

python merged-mining-proxy  -s 4 -w 8330 -p http://ssecreteloipool:222@127.0.0.1:8337/ -x http://photonrpc:photonrpcpass@localhost:9377/ -x http://blakebitrpcuser:blakebtrpcpass@localhost:blakebitport/

You can continue to add coins now by setting up the coin daemon, adding another -x http://user:pass@host:port/ line to the launch arguments for merge-mine-proxy, and incrementing the -s value. -s == <number of aux chains> * 2

That good to know may try it out just to see it work

[cinnamon_carter]

Ignatius looks like a fabulous resource , well done !! I may try it out this week, at the momemt I am 'sloshing it up' in the New York merged pool  !!

[bzyzny]

Ignatius, that looks like some very good info, thanks for sharing it. I'll definitely refer to that in the guide update.

[BlueDragon747]

Updating NY2 merge server expect some down time EU3 will follow once NY2 is working on new code  

Edit:
NY2 is done its only merging BLC+PHO atm other wallets need adding  

EU3 is done same as NY2 any problems let me know  


Note:

for anyone running a private/solo eloipool can you please enable

# Aim to produce blocks with transaction counts that are a power of two
# This helps avoid any chance of someone abusing CVE-2012-2459 with them
# 1 = cut out feeless transactions; 2 = cut out even fee-included transactions (if possible)
POT = 2

and the Blakecoin network is as follows did not notice earlier

# Network ID for the primary blockchain
UpstreamNetworkId = b'\xF9\xBE\xB4\xD2'

[mogrith]

Nice tease what do we call the coin between PHO an DIRAC?  Ƀ the symbol formerly rejected as BTC  BlicCoin?

AT and Dirac  I can at least type without google search to find it

[BlakeBitcoin]

BlakeBitcoin due for release and merge mine very soon 

[BlueDragon747]

I have the pools ready to go on all of them just waiting for wallets atm  

[BlakeBitcoin]

I was mining Myriadcoin with Myriad-Groestl but now i want to try Blakecoin someone can help telling me with the best miner and settings for a ATI 5850 please.

[BlueDragon747]

I was mining Myriadcoin with Myriad-Groestl but now i want to try Blakecoin someone can help telling me with the best miner and settings for a ATI 5850 please.

The default cgminer.conf that is included in any of the pools "Getting Started" is fine for that card can tweak the intensity to about 10, its a simple kernel not many extra options best thing to do is drop the memory clocks and raise the core clocks or just drop the memory and save some watts 

[jetxm]

Thanks BlueDragon747 now im mining Blakecoins!  . Im starting to like this coin , good dev

[BlueDragon747]

Thanks BlueDragon747 now im mining Blakecoins!  . Im starting to like this coin , good dev

[Angelie1LTC]

How about this coin?Is it still alive?

[BlueDragon747]

How about this coin?Is it still alive?

yep alive and kicking especially with the Merged Mine Pools BLC+PHO+B+ 

http://eu3.blakecoin.com
http://ny2.blakecoin.com

[mogrith]

Or merge mine BLC

[BitcoinForumator]

Is Dirac Coin a new coin that will be launched? Or just a rebranded Blakecoin?

[BlueDragon747]

Dirac and AT are to be released both new coins no rebranding going on here

Blakecoin - BLC is here to stay
