Can multiple crypto currency clients connect to port 9050 safely? Or should I make a unique SocksPort entry for each client in my torrc file as mentioned here: https://www.torproject.org/docs/tor-manual.html.enDefinition of "SocksPort" as mentioned on torproject.org: SocksPort PORT|auto
Advertise this port to listen for connections from Socks-speaking applications. Set this to 0 if you don’t want to allow application connections via SOCKS. Set it to "auto" to have Tor pick a port for you. (Default: 9050) |

What's up guys? Check out all of the items I am selling on eBay right now right here: http://search.ebay.ca/?sass=ibuyvideocards&ht=-1These are not my cards, they are my crazy friends who does not have an ebay account, but I can assure you they are all in great condition and I am putting up my own reputation to back the sale. The buyer of any auction can make payment in bitcoin if they so choose. |

The Bitcoin community needs coders/programmers/techies/hackers/etc more than miners and speculators. Don't know anything about programming? That's OK! Google to the rescue: https://code.google.com/edu/courses.htmlThe majority of the bitcoin client is written in C++ however python and Java projects are also quite prevalent. It's a billion degrees outside, so cool off in front of your computer fans and start learning to code! |

And then I will promptly call my credit card company crying that I can't find my credit card, file a police report saying I was robbed (should only take me about 15 minutes), and steal every penny of my money back from you. Every, single, time.Any takers?  |

I figure we send in Gavin and Bruce... Both wearing suits... Lots of chairts, graphs, financial know how, numbers, etc... It should be an easy sell to get the sharks to invest $1,000,000 or more dollars into Bitcoins. (If they have not already, that is!) Or possibly even into an ASIC mining project? A huge initial investment by the sharks followed by all of their loyal followers investing would be a great kick-starter for the Bitcoin success path. Thoughts? Shark Tank Info Dragon's Den Info |

Just like "they" did with the pools. When somebody got out of line (when a pool got too large of a hashing share percentage compared to the network) then they would be miraculously attacked, DDoSd, taken offline, whatever... while lots of the smaller pools received no beatings.Now it seems as though pool DDoSing has died down for the most part as nobody really has a large enough share of the network hashing rate to warrant anybody to worry as far as I know. These last few glitches with MtGox don't add up to a whole lot other than a financial company making some very very strange (almost unexplainable) errors that inevitably end up driving more market share to places like TradeHill.com, CaVirtex.com, Etc... Maybe we should just do as they want us to do to speed this whole thing along and stop dragging Bitcoin's credibility through the mud (by making MtGox repeatedly come up with odd/random errors). /conspiracy theory ramblings |

If you don't send your coins to/from an IP obviously  Say you generated a block of 50 coins (ie. didn't buy them anywhere, no trail yet) and then spent them from your machine later to purchase something you didn't want anybody to know about. Or the funds just happen to go to an unscrupulous individual in general and when he cashes them out them somebody wants to speak to you (the person who funded him) for some reason or another let's say. Could somebody tell simply by looking at the block chain or other factors what ip address sent or generated what coins? I know messages can be sent with blocks. Is any information related to the owner's computer stored at all in the block chain basically is my question? |

I can only think of one... Choose a list of ~100 ip address that are constantly "connectable" found by tracking this graph every week or two: http://maps.google.com/maps?q=http://c1958612.r12.cf0.rackcdn.com/bitcoin.kml (not actually that graph, because it is a backup, apparently the live version by MagicalTux is down right now) and add them to your firewall? To only allow those IPs to connect to port 8332 or whatever port you were running bitcoind on? Another option would possibly be changing (to say port 52395 or something) and hiding your bitcoind port, creating the same firewall mentioned above, and marking it "invisible" to any other "port scanners" or what not? That way nobody would even know it existed or that the server was online (unless they were one of the 100 people you automatically connected to). Ideas? Thoughts? |

How many possibly bitcoin addresses are there exactly?
How long does it take to generate one?

If this is true... Encryption is not some magic dust you sprinkle on an application and it magically becomes secure. If you can come up with a wallet encryption scheme that has more upsides than downsides, there's a good chance it will be implemented.
IMO, that's just inviting disaster. The client should only be running on machines that are inherently secure. Doing this will encourage people to run the client on insecure machines, which will compromise their wallets even if they are encrypted. Strong passwords will be forgotten, leading to lost BitCoins. Weak passwords will be brute forced, accomplishing nothing.
Emphasis mine. Then why do we not simply force the use of the windows security center into all windows builds of bitcoin by default (or enforce the windows security center to be running unless the user is "advanced" and clicks otherwise)... The windows security center for those are are not aware is a notification nag system on windows that constantly nags the user to download the latest virus scanner, make sure their firewall is up, to enable the virus scanner and all updates, etc... If every "basic" windows user was forced to do this by default, I think we could cut down on 90% of the possible thefts by trojan at least - all without much work on our part. Linux systems would be considered safe for now from trojans and would not require the default security settings. |

Like every time I mine a block almost, I am told that the miner is idle.
Could it be that since I am personally mining about 16 blocks per hour that the small bitcoin testnet distribution is not verifying these transactions fast enough?
I have just begun to run phoenix miner in an attempt to see if it is just the miner... however I have run both miners on the regular blockchain recently and have not received this number of "job finished" errors...
There appear to be smooth runs of poclbm miner that show next to no "miner is idle" warnings for quite a few blocks in a row, and then all miners seem to go to spotty chunks of mining time where every other block found there is a "miner is idle" warning.
Could it also be that I am maxing out my "m1.large" EC2 instance in terms of power? (I highly doubt it however, as it is showing between 99% and 100% "idle" CPU with all other values at or near 0% in the linux top command.
I am showing 27 connections on testnet. My port is forwarded.
There are approximately 10 5870s on 2 machines transmitting about 3,7Ghps from my home to the amazon cloud.
I will report back with the results from phoenix miner.

I am working on creating a mysql database and don't want to waste any extra storage space.
So what should I make an entry for a bitcoin address?
CHAR X length? (is the address consistently one length?)
Or VARCHAR X length? (does the address change in length from user to user?)

Why don't we focus at least some effort on convincing a small ATI video card manufacture to make a 5870 * 4 core video card with only 256MB of cheap/slow ram?
That could theoretically do about 2.4 Ghps for maybe 600 watts of power. I don't mind plugging in 4 pcie connectors to power it, either.
The 5870 technology is 2 years old already.
All we would need to do would be to come up with about 1,000 initial orders at say $1,000 a pop and I bet we could convince somebody to make a board like that for $1M USD, no?
I would pay $1,000 for a 2.4Ghps card.

Or how long do I really have to wait to be "sure" that the generated block + 50BTC contained within it are valid?
The default on the bitcoin client is 120 confirmations.
How would somebody manage to "trick" you for 119 confirmations in this day and age at the current difficulty level?
As soon as 1 or perhaps 2 confirmations come in I fail to see how you could declare an older block invalid.

When interacting with the bitcoin client, you have the option of passing two (different?) commands to it that seemingly always return the exact same result.
getblockcount === getblocknumber
Or does it?
And why?

Apparantly pushpool requires a minimum difficulty of 256 to work 100% properly, so I attempted to increase the difficulty (from ~45) to 256 or higher so that I could fully test pushpool on testnet before making any errors on the real blockchain. I should have known this would not be possible since the bitcoin protocol has some sort of difficulty increase limiting factor built into it by default, does it not? I am curious... did testnet just hit (or almost hit) that difficulty increase limit? It's surprisingly close to a 4x increase right now (sitting at ~175 difficulty). If anybody wants to join me in upping the testnet difficulty over the next few days, feel free!

What kinds of attacks have you pool operators been noticing and what was your best bet to mitigate it?
On a side note, the attacks seem to be less frequent and more targeted towards the largest mining pools recently... perhaps they are somewhat benevolent in nature and only trying to "even out" the playing field?

Or are both blockchains kept in the same file, I wonder?
I have run both blockchains from an ubuntu install and only see a single wallet.dat file in my /.bitcoin folder.

So I was running bitcoind through an SSH screen on ubuntu 11.04.
The connection terminates randomly after long periods of inactivity.
Before I disconnected once, I had a running ./bitcoind screen open...
Now when I re-connect I cannot seem to find it, but bitcoind is still running.
How do I go about properly closing bitcoind without corrupting the blockchain or worse?
