mutable-tx attack on Bitcoin
Has anyone noticed any effects from this "attack?" A couple of days ago when it supposedly started my block template latency shot up from .1 to .45 and has been high every since. If there anyway to counter this kind of thing? Any know bot-net IPs to block?
I'm asking because I haven't seen any discussion about it here...
Thanks
It's being worked on at a level above my pay grade. https://bitcoinfoundation.org/blog/?p=422Roy this issue you are pointing out isn't a bitcoin issue, its a site issue. The exchanges haven't been accountable for really anything that people have found an exploit which now requires them to be accountable for everything coming in and going out of their sites. So until they fix their own code nothing will change. |

Good story, and I it's good to see the someone is attacking bitcoin in away that it requires the exchanges to be more responsible for everything that comes into and goes out of their website.  Yes. Those attacks will show them their problems and if they are smart they will use it as a gift. It will harm bitcoin because it will invoke more bad press. The press already know bitcoin is volatile as it is. I doubt the problem with the exchanges will affect much. |

I don't believe your latency is related to some fake attack as I have been looking around at other p2pool nodes to see what their front-ends look like and noticing their latency's are lower than mine. If you are having a latency issue I would check your internet connection first. |

No 9332 is both mining and web page
9333 is p2p
So I am back to my original question. How do I change the website front-end port? The answer is still -w. You can't change the port for only the website front-end without changing the port for miners. The port for the front-end and the miners is always the same port. That's not true. I have seen P2Pool sites that have bitcoin set to port 9332 but when you try to access the front-end get a message that no page exists, and some have bitcoin on port 9332 and the front-end on a different port like port 80. |

how do I change the port 9332 to something else for the website front-end? I know how to change the port for the bitcoin but I need to change it for the front-end now. I have setup a second server on a different box, also does the server need to communicate with the pool on 9333 or can I change that port too?
Thanks,
https://en.bitcoin.it/wiki/P2Pool --p2pool-port PORT use port PORT to listen for connections (forward this port from your router!) (default: bitcoin:9333, litecoin:9338) -w PORT or ADDR:PORT, --worker-port PORT or ADDR:PORT listen on PORT on interface with ADDR for RPC connections from miners (default: all interfaces, bitcoin:9332, litecoin:9327) so to clarify the --p2pool-port is port that when you access it hits the webpage and not the mining pool for the coin(s)? |

So your update only only applies to the front-end that has the graphs? Will I get any thing out of it if I apply it to my P2Pool that has a different front-end?
Do you run a Vertcoin p2pool node? We need to do a hard fork of the network to fix a setting that was wrong when the network first went live. Has nothing to do with the graphs. I am confused by the comment after the question... I run a Bitcoin p2pool. p2pool.smoothrunnings.ca:9332/ |

When updating networks.py to a new identifier/prefix and a new spread setting, is it okay to keep the existing share chain data file for the new network? I know you can't run two network.py configs on same network, but it seems like keeping the prior share data wouldn't hurt the new network.
We'll probably bite the bullet and roll out the corrected SPREAD setting this week for VTC.
PS- It'd be nice if anyone else has tested my earlier diff to share feedback on it.

This is an interesting discussion, please let us know the results.
P2pool is important for bitcoin and making it accessible to more people is important. This type of change helps public pools - and that helps bitcoin and p2pool. Let's face it, many people won't set up their own p2pool node, they want easy and compared to pools that require registration, p2pool is easy.
Decreasing variance (since people are impatient and don't care about the math) could be helpful too.
Has been working well so far. The diff miners get is lower than it'd normally be, but not as low as if they did /1 to mine at the minimum share diff all of the time. The reason /1 goes lower is that it overrides the dust prevention code. So it's best to not just tell all public node miners to use /1, and instead only have people who can't stomach the variance and are willing to pay the tx fees do that (or they should use a normal pool). The node I'm testing on is http://vtc-us-east.royalminingco.com:9171/static/graphs.html?Weekand the code went live at the Feb 9ths mark (early morning). You can see from the pool shares graph the peaks/valleys have smoothed out, and you can see it happening in a similar way on a per-miner level on the miner graphs. I don't run a BTC node at the present time so I don't know what sort of share difficulties normally get assigned to workers on the public pools. The VTC p2pool network is over 5% of the global network speed and finds many blocks per day. So the behavior here might be quite difference than on BTC itself. Hopefully forrestv or someone with more knowledge and experience with the p2pool code base will review and comment. can you do a comparison shot of before and after? I still don't get what you have changed. Oops just saw you did that. |

wow newbs and weak hands you just suffered THE GOX.....you have been Goxxed' was that really 100 on btc-e just then......
if mark karples had a buy in on btc-e just before he released he just became solvent again.
Maybe this will be the conspiracy in order to save the ship. Well you know that famous saying, 'We will not go down without a fight!', well that's what MtGox is doing right now. In the end they will simply collapse in on themselves. I just hope the owners of MtGox have learned something from all this and apply what they have learned to the next crypto currency exchange they decide to open after MtGox is gone. |

I think they know they're done. This is probably just their death-rattle. If people still use them after this then I can't even.
I think your right. Instead taking the blame for f'n up they probably thought putting the blame back on bitcoin would save their shirts, and maybe it has a little bit but overall it hasn't. It's time for the owners of MtGox to close their shop and open a new one, hopefully they can apply what they have learned to the next exchange making bitcoin more stronger and stable. |

BTW kiddies, MtGox has the lowest price for BTC, all the other sites (check preev.com) are $600 to $700 USD, even cavirtex.ca is about $700 per BTC. I suspect more and more people as they leave MtGox will drive the price on that exchange and either keep the price going at the other exchanges as they pick up the slack and or drive up the price. In the end the largest exchange is going to take a heavy hit for their own stupidity. |

Sell Sell Sell! Lets have the price drop to $0.05 a bitcoin!!
The price will eventually go back up again.

The biggest problem is if you have been using a standard password in the beginning as had the machine accessible globally via internet.
You will have to reset to factory settings as most probably you have malware on it.
Hi - The ORIGINAL SD Card with MinePeon installed did have the default password. Once I was hacked (the first time) - I switched out an ENTIRELY NEW SD Card with MinePeon reinstalled -- with a VERY secure password (25 char+) -- The Hacker is back -- and seems to have broken that one too. He hasn't broken it, he's just found another way in. He could have modified something in the OS, maybe a command that you are using that executes something that gives him access. |

There was an article posted in December of last year, that says in it: "P2pool is technically a mining pool, but one that acts like solo mining in terms of the end user's view. You enter the pool using your wallet's address, rather than signing up to get an account, and the payments are automatically paid out once blocks are found by anyone on the pool. This cuts down on the middle man and also reduces the time it takes to get paid, although it does bring up another issue: you will get a ton of payments out of it. With each new payment you get, you are potentially adding some bytes (around 230) to your transaction size for when you send coins to someone. As this number grows, the cost of sending the coins also grows along with it." Does anyone know what this comment means? "With each new payment you get, you are potentially adding some bytes (around 230) to your transaction size for when you send coins to someone. As this number grows, the cost of sending the coins also grows along with it."Here is the original article: http://www.michaelnielsen.org/ddi/how-the-bitcoin-protocol-actually-works/Thanks, I think that's a reference to dust... Could you be any more vague? LOL |

I would take that story with a pinch of salt! The guy can jump on a 16 hour flight from Australia but can't be arsed to upload a 30 second video clip from Gox Lobby to YouTube! LMFAO!  Good point A lot of creativity - very little documentation. Who jumps on a plane without an appointment? Does a trip from Australia to Japan really take 16 hours? Maybe the guys is one of the early investors of bitcoin that he's got a lot at stake, and flying out to Tokyo is just a drop in the bucket for him money wise. Not a lot of us are like that but some people are, and the ones who have had enough of MtGox BS I could see doing something like that. |
