Can You help mi with this? Thanks!

[moopless]

Sounds like bitbar has a different block structure. We will have to change the block structure in block template. Can you find out what the header sizes/requirements are for bitbar?

[abweb]

How I check this? Block template:

bitbard getblocktemplate {}
{
    "version" : 3,
    "previousblockhash" : "0000000020244248bdeba1906c0f50c6293016ec70f6f047ee9f793deda4181b",
    "transactions" : [
    ],
    "coinbaseaux" : {
        "flags" : "062f503253482f"
    },
    "coinbasevalue" : 195625,
    "target" : "000000002f4ec700000000000000000000000000000000000000000000000000",
    "mintime" : 1373283450,
    "mutable" : [
        "time",
        "transactions",
        "prevblock"
    ],
    "noncerange" : "00000000ffffffff",
    "sigoplimit" : 20000,
    "sizelimit" : 1000000,
    "curtime" : 1373285674,
    "bits" : "1c2f4ec7",
    "height" : 14654
}

It should be in the official documents for the coin. I went looking for them and those don't exist. I can go to the source if need, but my initial research shows that this is just a novacoin fork. Can you try with the PoS branch?

git checkout PoS

[abweb]

I tried and I have another error

I put this check in when using PoS coins.

2013-07-08 15:10:39,470 ERROR template_registry # [Failure instance: Traceback: <type 'exceptions.Exception'>: Invalid Public Key: Check CENTRAL_WALLET

For PoS, you need to have the pubkey instead of the address for CENTRAL_WALLET.

[abweb]

Works! Thanks :)

[sunggeorge]

Thanks! Really save me lots of time.

I never know it's pubkey for POS wallet.

[tbourvon]

Bump! This is happening for Hobonickels, a POW coin. My worker seems to mine just fine but I am worried this might impact my rewards...

[ghost]

ok, where we can find this pubkey. I am trying to setup feathercoin pool with no success - i am getting the same error as abweb?

[nicoschtein]

Use ahmedbodi/stratum-mining , this repo is not maintained any more.
