Updated the code. Payouts to worker addresses now work! I open my public node to miners again. However, unlike with other p2pools, you have to specify your public key (not an address!) as username.
Since I am not a developer, I used a crazy python hack containing several lines of shit-code to achieve it. However, it works and generates payouts to workers. I have tested it in the testnet.

To point worker to my (or any other) public node you have to get a public key:
1) launch bitbar

2) in bitbar directory, run
you will receive a hex string, call it <your_new_pubkey>, which is the public key to a new address in account "someaccount" (you don't have to keep it secret, as it's public)

3) (optionally) make sure it works as supposed to: run
you should see a new address, and
will return JSON object, which is expected to have 'isvalid' and 'ismine' properties set to 'true'

4)use <your_new_pub_key> as a worker username when connecting to a public node, just like you use your address with other coin p2pools. You may now close your bitbar.

Added bootstrap address.

I closed access to port 8333 from outside because of this:


If I open it, you will be able to connect, but all your work in this case will generate payouts to my address! So it only works like described above: launch bitbard and p2pool on your computer and point your workers to it. Your p2pool node will connect to my p2pool node (and other running nodes), grab an address from your local bitbard and generate payouts to this address.

I am trying to enable payouts to worker addresses now and will update if I get it working. Please read the thread if you want more technical details. Stay tuned!

Which delivery service is that?

Commited some more fixes. Already found 2 blocks. Read this: https://bitcointalk.org/index.php?topic=217894.0

One more fix: disable reward rounding to cents, which is used in NVC but not BTB.
Previously found blocks generated 0.17 BTB instead of 0.172421 (e.g. http://btb.cryptocoinexplorer.com/block/0000000011f9f1834ebb07844db877b6016d9a8b0cb7191a13229066976ef197)

Fixed links to block explorer on the stats page.

First block found!

One more fix. Re-download the source, please.

Download the code from github and clear data/bitbar directory.

All work submitted to a node by workers goes to the node's address!

Oh crap   I shouldn't have changed coinbase type to pubkeyhash.

The situation is like this.

Bitcoin/Bitbar/etc. address is encoded 160-bit hash of the public key. In Bitcoin, it is enough to provide coinbase (generation transaction) output. In PPC/NVC/BTB, coinbase type must be TX_PUBKEY, not TX_PUBKEYHASH, which means that you need full public key to create coinbase, not its 160-bit hash. So when a worker specifies its address as a username, the node cannot give it coins from the coinbase. Type of coinase outputs was TX_PUBKEY in NVC p2pool, so it didn't create payouts for workers. I changed it to TX_PUBKEYHASH, and as a result, the block was not accepted by bitbard. i will now change it back to TX_PUBKEY, so nodes can only mine to their own address. Worker names/addresses will be ignored (just like it is in NVC p2pool).

I'm not sure either. Now reading the logs. It definetly tried to submit it to bitbard, but then... I need a couple of minutes...

Your estimated time to share is  (Time_to_share * Local_hashrate / Your_hashrate). First two are reported on the stats page.

Thank you for your help. I hope we will find a block eventually. Estimated time to block now is 6.5 hours.

Current share difficulty is printed on the stats page. Pseudoshare difficulty can be anything, because it doesn't really matter. You can tune both of them by setting your username like this:
Here, BL5vKqnKHmnzvLZ5qCxETNnMzTM6CCdUzf is payout address, 0.01 is share difficulty and 0.001 is pseudoshare difficulty. However, you can only set share difficulty higher than current p2pool share difficulty, so this is only useful for miners with high hashrate. You can find more p2pool basics here https://bitcointalk.org/index.php?topic=18313.0

In p2pool, there are two types of shares.

'Real shares' are propagated by nodes in the p2pool network, and payouts are calculated based on them.

'Pseudoshares' are shares of small difficulty, which your minerd reports. If one of those pseudoshares meets difficulty requirement for a real share, it is accepted and propagated as a real share. Payout is based on number of submitted real shares.

Public node (0% fee): http://78.27.191.182:8333/

Issues fixed. Everything seems to be working now (including worker address payouts).

Strangely, payout does not increase for worker addresses
