Looks like it pulls and rotates the default mining addresses from bitcoind.

How do you show blocks found that is more than a day ago? I've been looking at the code but I can't seem to find it or rather, changes I make doesn't seem to make it happen. So, as you can tell, I'm not a programmer and am only good at changing letters here and there.

Thanks much.

I saw that too.  Why would you want that?

Anyone else try this?  I'm getting errors all over the place:

Not working for me, can't connect to peers.......

According to the merge it: "Essentially this pulls new addresses from bitcoind, using the account 'p2pool' - which I didn't have, so I created a new account on bitcoind called p2pool & restarted p2pool - no difference.  It's screwed.

Is it possible to do a git clone of the previous version?

[yslyung]

whooops . . . new does not mean good. oldie but goldie here running the .exe version

again the old saying goes : ain't broke, don't fix it

does anyone have any experience with the following scenario ?

does your qt or bticoind crashes when hashrate is over 550th/s ? mine did couple of times, if it's below 550ths it runs normal but once it passes the 500 + th/s mark, bitcoin qt crashes p2pool showing "lost contact with bitcoind/qt"

but when i checked (qt), it seems to be running but i just close and restart it then all goes back to normal. p2p was untouched.

OK, I noticed that the latest git kept trying to connect to  1.202.128.218:9333 - so I checked the IP:

CHINA?  WTF?  Has forrests git repo been compromised?

[mdude77]

I threw the last git I retrieved from p2pool on 12/15/2014 up on my url:  p2pool-master.zip.

p2pool  is single threaded.  My hunch is around 500 TH/s p2pool is taking so long to server your workers that by the time it gets back to checking bitcoind, it's been so long it thinks bitcoind is hung.

You might want to check out using ck's proxy to point to p2pool so your node only sees 1 worker.

Need a little help.

How do you show blocks found that is more than a day ago? I've been looking at the code but I can't seem to find it or rather, changes I make doesn't seem to make it happen. So, as you can tell, I'm not a programmer and am only good at changing letters here and there.

Reason being, it looks really really really bad when recent blocks is blank.......

Thanks much.

Anyone?

Can someone clarify something for me?  How much bandwidth does running a node generally eat up per day?

If you have a server dedicated to P2P with bitcoind running and have your payouts going to another wallet on a different server why would you need to implement address rotation with bitcoind? I read the post on github and do not see why this would have been a benefit. Obviously I need a better education with this aspect. Can someone just point me in the right direction so I can read up on this please.

You would have no need for this.

Address reuse is generally frowned upon from both a security and privacy standpoint, if you were using the node bitcoind wallet this would be a big security improvement.

Privacy
Address reuse harms the privacy of not only yourself, but also others - including many not related to the transaction. In some cases, these risks are serious enough that they are likely in violation of reasonable consumer protection laws.

Security
Bitcoin does not, at a low level, have any concept of addresses, only individual coins. Address reuse, at this layer, requires producing multiple digital signatures when you spend bitcoins. Multiple situations have been found where more than one digital signature can be used to calculate the private key needed to spend bitcoins. Even if you spend all the bitcoins claimed by this private key at once, it is still possible to double-spend them in theft before they confirm. While the situations for finding the private key from signatures have been fixed, it is not prudent to assume there aren't more such situations yet unknown.

In the case of spending all the TXOs in a single transaction, there is an additional risk if someone is actively monitoring the network for vulnerable transactions: upon receiving such a transaction, they can split up their double spends such that there is only one ECDSA verification per transaction (making a single transaction for each TXO); this will cause the attacker's transactions to relay across the rest of the nodes faster than the legitimate one, increasing success of a double spend.

Coincadence gives pool stats and all blocks ever mined from p2pool.  It is very useful.  However, if you are asking how to modify your p2pool server website to show more than just one day of blocks than that code is in p2pool/web.py.  Find the area of code which is "web_root.putChild('recent_blocks', ..." and in there it defines the time period.  Several lines down it should say something like "24*60*60" which represents 24 hours, 60 minutes, and 60 seconds.  If you would like to show more than one day of data just multiply this number larger by the number of days you would to display.

Perfect, I was dumb in thinking that people were no longer using the node bitcoind for payouts, thank you.

Thanks for this link, was able to get my node back up again after faffing around with that latest release.......

When I git pulled it, it had been up for over 12 hours - I can't believe we were the only people to have had problems with it, surely? I mean, wouldn't forrestv have tested it first?    I can't remember ever having problems with new releases, not as severe as this one anyway.

I'd still love to know who my Chinese friend is who's hammering my node from 1.202.128.218:9333 - I ended up having to block it
