[ANN] [XJO] Joulecoin | SHA256 | First SHA256 data coin | 0.10.4.3

On the rise. 

Most alt coins I have noticed have been steady for a couple of months.. it's quite interesting.

Joulecoinnnnnnnnn!!

Seems the double pool start has worked well, no down since setting up.

[1Referee]

Nice growth again in price, it even touched the 300 sat again.

I know it's easy to "pump" XJO with low amount, but still, nice to see.

Agreed, seems someone else has some interest in Joule .

Looks like someone put up 1.5 Thash/sec on mininngpool.co.

[spazzdla]

Anyone else mining XJO?  I've got 200 GH/s committed to it's security .

[1Referee]

Some nice buy support in the XJO orderbook, keeps the price stable 

Not long ago there was barely buy support, something has changed 

[spazzdla]

Holy cow someone is dedicated to mining this.. who ever wwwDan is on miningpool.co :O!

3THash/second he/she has  been dedicating for over a week..



I wonder.. WWW are you on this forum?

[spazzdla]

Bam?  Any joule ppl out there?

[spazzdla]

No more Joules out there?!

The name and metrics of this coin are just so awesome!!

I did a little mining of XJO before I found UNO. I've been working with the UNO people. It's a very active community.  I like XJO, I just don't see a lot of action here. 

[techman05]

Xjo would be nice if there was a good conversion rate. Coinmine.pl shows xjo to btc much higher than in reality.

I know there's no such thing as a free buck( dollar ), but I'd mine Jule to the ends if their values were accurate.

I'm looking at adding Joulecoin to my MinerSwitcher setup, but I've run into a snag: I can't get the block reward out of joulecoind.

MinerSwitcher depends on ProfitLib, which in turn depends on a set of coin daemons and some exchange data (currently from Cryptsy, but I'm looking at adding support for more exchanges) to determine which coin to mine at a particular time. 

This block of ProfitLib code uses python-bitcoinrpc calls to retrieve the current block reward:

Code:

        b=jsonrpc.ServiceProxy(url)
    
        # get block reward, including transaction fees
        # note #1: Novacoin (and coins derived from it?) report
        #          1% of actual value here
        # note #2: Namecoin doesn't support getblocktemplate, so get 
        #          coinbase value from last block
        # note #3: PPCoin doesn't want any parameters passed to
        #          getblocktemplate.  Bitcoin requires at least 
        #          an empty dictionary to be passed.  Others don't
        #          care.
    
        reward=Decimal(0)
        try:
          reward=Decimal(b.getblocktemplate()["coinbasevalue"])
        except:
          pass
          
        if (reward==0):
          try:
            reward=Decimal(b.getblocktemplate({})["coinbasevalue"])
          except:
            pass

        if (reward==0):
          try:
            vouts=b.decoderawtransaction(b.getrawtransaction(b.getblock(b.getblockhash(b.getblockcount()))["tx"][0]))["vout"]
            for j, vout in enumerate(vouts):
              reward+=vout["value"]
          except:
            pass
                
        if (coin=="NVC" or coin=="DEM" or coin=="OSC"):
          reward*=100

It tries three different methods, determined over the course of adding 25 other coins, that work:

* getblocktemplate with no input
* getblocktemplate with an empty input
* if getblocktemplate isn't available, get the coinbase value from the first transaction of the last block mined

This works for every other coin, but not for Joulecoin.  getblocktemplate is a valid call; joulecoind getblocktemplate returns what you'd expect.  There appears to be a communication error between python-bitcoinrpc and joulecoind.

I knocked together this test script:

Code:

import bitcoinrpc
import jsonrpc
import sys
from decimal import *
import pprint

url="http://salfter:redacted@localhost:8844"
#url="http://salfter:redacted@localhost:8332"

b=jsonrpc.ServiceProxy(url)

pprint.pprint(b.getblocktemplate()["coinbasevalue"])

The first url definition points to my joulecoind instance.  The second, commented-out definition points to my bitcoind instance.  If you run it against bitcoind, you get the current coinbase value:

Code:

2521327109

Run it against joulecoind, however, and you get this:

Code:

Traceback (most recent call last):
  File "test.py", line 12, in <module>
    pprint.pprint(b.getblocktemplate()["coinbasevalue"])
  File "/usr/local/lib/python2.7/dist-packages/bitcoinrpc/authproxy.py", line 120, in __call__
    response = self._get_response()
  File "/usr/local/lib/python2.7/dist-packages/bitcoinrpc/authproxy.py", line 146, in _get_response
    parse_float=decimal.Decimal)
  File "/usr/lib/python2.7/json/__init__.py", line 351, in loads
    return cls(encoding=encoding, **kw).decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

Something is going seriously wrong here.  I built joulecoind from GitHub source yesterday:

Code:

git clone https://github.com/joulecoin/joulecoin
cd joulecoin
./autogen.sh && ./configure --with-incompatible-bdb && make -j3 && sudo cp src/joulecoind /usr/local/bin

It's hard to reach any other conclusion than that there's a bug somewhere in the Joulecoin codebase, given that I have 25 other coins configured and running properly with the same code.

Sal you scare me!!!

NOT MY JOULECOIN!! I like joulecoin... .

Are you sure you have the correct port, port is open, etc?

Try telnet to the host/port and see if you can connect.

The getblocktemplate command returns the information you are looking for:

Code:

{
"coinbasevalue" : 1600000000,
}

That's about what I'd expect, given that I'm not sending the username and password. "Server: joulecoin-json-rpc/v0.9.2.2-beta" indicates that I'm talking to the right port, at least.

Like the website. I am a newb to all this mining stuff and want to say my first official block to mine was the Joulecoin. I noticed the website and it is looking good. Any word on getting a market tab on your website? Like a market place. People could add hardware new and used. Maybe even an auction function. 

[smalltimer]

is this coin under value right now or do i miss something?

[spazzdla]

is this coin under value right now or do i miss something?

?? What do you mean?

[smalltimer]

is this coin under value right now or do i miss something?

?? What do you mean?

i mean for a no premine fair launch coin (i assume) which has still running chain and is functioning and old coin (not part of the shitcoin wave) and dev still somewhat around AND exchange listing this is a bit beaten down. Can be pumped with very small bankroll.

All it needs are some nice things/goodies/updates and this can be worth multiple times the current exchange price.

0.5 BTC (couple of hundred dollars) invested sends the price 300%+

that's what i mean.

Are you people mining just to keep the house warm or what?

Currently daily cost of running this network are:

0.039936 btc

please tell me why this is not under value or why it should decline much further in price?

[spazzdla]

I'm mining it because I like the name and metrics...  The issue with sending the coin skywards is you have to have the capital to put up a buy wall to keep it there..  Although even 20k USD would allow you to go nuts and put up a large buy wall.

I really really like the min payout amount for mining, IMO BTC should have one but that will never happen.


So yes.. I am mining it to keep the house warm lol.

I cannot see this coin dropping past $4k market cap .
