Surely if you want to limit bandwidth, just don't run the core all the time.
A build in limiter is coming with 0.12. Great news. When is 0.12 slated to be released? rc1 was just a few days ago (Sunday). I think the goal was by the end of January depending on how the testing goes. |

Looking at program rules for bitcoind and QT, I could see that there were no restrictions to incoming traffic. I also tried temporarily disabling the firewall. I still get MyIP:8333 is unreachable on bitnodes.21.co. My router is a D-Link DIR-655, Hardware Version: B1, Firmware Version: 2.11NA. After setting up port forwarding in my router for 8333 directly to the computer running Bitcoin core and eliminating my firewall as the problem, I'm not sure what to try next. Is there something else I can check that could be preventing my Bitcoin client from accepting incoming connections from other nodes? Can you look at the router logs and see if you are getting messages about the firewall portion and see if it is giving any messages when you try to probe that port? I didn't see if you answered from above, but can you connect to the bitcoin port from other machines on your network? |

Protecting it is very difficult depending on who you are worried about. A mining pool about 3-4 years ago seemed to have been hacked by a tech at the vps provider. They covered the ~3000 BTC loss themselves. Revisiting the architecture to minimize the exposure of the hot wallet might be a good idea if this will eventually handle any large sums. Hi!
In my next project, I would like to run an altcoin on a Ubuntu VPS and integrate this in my project to withdraw.
Therefore I ask how can I protect the funds on a VPS. I have already experience that I can allow a IP to connect with the RPC and the wallet shouldn't be used as root but as a new user.
Cheers

What is actually the percentage needed for this secession democratic-fork to happen ? If this is 50%, I agree with you that it is no enough. Even 75% could be considered not enough in most of the situations.
I think it will be 75%, although as of now, no changes have been made to the fork so this cannot be known until they actually commit the changes. As theymos said above though, 51% is enough since pro-fork miners could just reject blocks from anti-fork miners making the percentage go above any arbitrary percentage quite quickly. For a hard fork just miner voting is not sufficient. Long term, the number of bitcoin hard forks will need to be kept to a minimum - kind of like a "hard fork" for smtp/ftp/dns/'tcp/ip' etc are exceedingly rare - because this type of political turmoil is a huge risk factor for bitcoin, not to mention the risk that a critical bug is introduced. Things like hard forks to enable sidechains with opcodes such as OP_SIDECHAINPROOFVERIFY, will enable a lot of experimentation without needing hard forks going forward. Perhaps re-enabling select other opcodes. Stability of bitcoin at the protocol level is extremely important due to the risks involved in changing it both technically and politically. If it was still 2008, changes would be much easier but a huge ecosystem and value gives no room for errors. It is like upgrading the engines on an airliner while in the air. :-) |

Can you connect to that port from other machines on your network? (Just to ensure that the firewall is really off for that port). Eg with telnet. |

Yeah I've figured it out few minutes ago but as I've said in my previous post there's no input value:

For:
7f502f28ca8d162300a1bbc8cb7dfa6f38533596ac97c29e1d1de9ca614ae350
Total Inputs 11.69569708 tBTC
Total Outputs -11.69563674 tBTC
= 0.00006034 tBTC fees (subtracting total outputs from total inputs)
For the second, total inputs and total outputs are the same: 506.68468049 tBTC
So there are 0.0 fees.
Does that make sense?
If you aren't asking how to calculate the fees for that transaction as it was confirmed, I am not sure what you are asking.
I'm actually doing it via Bitcoin API and PHP. I tried gettransaction but it doesn't print the fee amount. You might try using getrawtransaction and then subtracting the outputs from the inputs. This has some more info: http://bitcoin.stackexchange.com/questions/11411/in-getrawtransaction-what-is-the-vout-integer-in-the-vin-list |

this is a great thread and a good question.
Hopefully more people can weigh in on their thoughts. I really would like to know exactly how that would happen
or how it would be decided
I agree, very good question and topic. I have the same question, can it ever go past 21 million coins and who and how is it decided? If someone changed their code from the 21 million limit to a higher inflating limit, it becomes an alt-coin and bitcoin itself goes on with the 21 million coin limit. There would be a fork between the two block chains, one fork would be bitcoin, the other inflate-a-coin or something like that. Everyone who had coins pre-fork would have coins on both forks. In all likelihood, the fork with the inflation built in would lose value quickly since it would not hold value over the long term. Smart people would sell their inflate-a-coin coins and buy the real non-inflated bitcoin. thanks for the response. What does this mean that "smart people would sell their inflate-a-coins..." How will these coins differ from Bitcoin? So if I have 2 bitcoin in a wallet online are they still bitcoin? Let's look at what happens: 1. You have bitcoin as it is now. 2. Someone decides to fork bitcoin to create a new coin that includes some inflationary provisions. 3. At this point you have the original bitcoin and the inflate-a-coin fork. 4. Every person who had coins on the original fork has coins on both forks right after the hard fork. 5. Bitcoin continues along with the 21 million limit. Inflate-a-coin also runs in parallel - assuming you got people to switch to this new fork. So you have the smart people who are saying, "inflate-a-coin is not a good store of value, so I'll sell my inflate-a-coins and buy bitcoin with them. Then I can buy back more of the inflate-a-coins later if I want to for some reason and get more of them since they are losing value due to the programmed inflation." OK, that makes sense thank you for a great explanation. Who are the potential people or groups that would be interested in a fork to create a new coin? I think the people or groups who are interested are people who want the ability to have a stealth tax (inflation) on everyone else in order to skim money from a large number of people either for their own pockets or for the power they'd get from being able to hand it to others. These are the people who want power and wealth and are willing to skin everyone else to get it no matter the consequences to people, states, or the world. |

Beware if he removed 1644, someone could have copies of your private keys. Your service guy could have copied your wallet, and a virus could have. 1644 doesn't do that in the variants of which I am aware, but there could have been others or it could be a different variant. So, if it were me, I'd move my coins to be safe. Even if your service guy is honest, there could've been other people around who were not. HI,
Thank you for the much appreciated information on the forum "Untrapping my btc". But I have encountered another
problem I sincerely hope that you can help. Just recently I took my computer in for service, because for a week it
wouldn't allow me to connect to the internet...So the serviceman ran various virus and maleware sweeps.
He told me that he found and removed 1644 . I also noticed that my desktop wallet icon was missing. I immediately
checked the "add remove programs" section it showed the it is still listed. I don't understand what could have happened to the icon. This happened before I had the chance to download the latest qt from the link that you
provided...I remembered to backup the wallet.dat file so is my btc within that file, and by downloading from the link
you provided will that create a new wallet, and by me having the wallet.dat file will from link automatic configurate
itself i.e will open will same passphrase, or what should I do at this point... I hope to hear from you SOON!!!

If you are talking about Bitcoin Core, you can go here and help translate: https://www.transifex.com/bitcoin/bitcoin/It looks like the Russian translation is about 78% complete. Click the "HELP TRANSLATE 'bitcoin'" and sign up. Unfortunately my Russian is now very rusty or I'd help. |

Almost immediately after publicizing their support for Gavin Andressen’s BIP 101 and Bitcoin XT, Coinbase was removed from Bitcoin.org. The de-listing of Coinbase’s bitcoin wallet platform followed a major upheaval in the Bitcoin community, as many of its members began to contest against Bitcoin.org’s unsupported decision to remove the world’s 2nd largest bitcoin wallet application from its website. http://www.newsbtc.com/2016/01/10/bitcoin-org-violates-its-mission-statement-to-censor-coinbase/I think their argument would be that Bitcoin XT is a fork and therefore and alt-coin and therefore not bitcoin and therefore they are no longer supporting bitcoin. Right or wrong, I believe that is what they would say at least in part. |

Thanks guys. Such huge numbers it's difficult to fathom, but that really helps put it in perspective.
And that is the problem. It is very difficult to fathom the size of the space even looking at the numbers. It is easy to think, oh, the number is twice as long, so twice as hard, so I'll just search twice as long when in fact it is nothing like that. Without consciously thinking about it it is hard to grasp. Even thinking about it, the scale is just so immense it is hard to appreciate. Shoot, even looking at the math it is hard to appreciate the enormity of it. Glad Shorena and Danny beat me to the math!  |

If you intend on continuing any type of darknet market activities I highly reccomend learning to use tails or something similar. You are just begging for a repeat of this situation if you continue to use Windows for these types of things.
Definitely good advice. Or if you are handling a substantial number of bitcoins, buy a PC to use only in off-line mode. And don't use Windows with it. |

Then just format the hard drive and reinstall your OS. Since you are trying to delete your private keys anyways, that will take care of that for you.
...
If you already have a backup, keep it. If you can make one, do so. It doesn't hurt to have it so that if they send coins to that address you (or someone) can sweep them and not let the scammers keep them. If you wish to make their life more difficult in terms of using that key, post both the private and public key here. Then someone will no doubt monitor it and try to beat the scammers before they make bitcoins from it. |

Yes, Core 0.11.2. I start it on and off when I need to do something with my wallet. Usually it catches up several days and then I do a transaction. This particular transaction was sent with 0.00013 BTC fee which seems reasonable?
It does in the abstract, but that is just abstract. Currently, Bitcoin Core uses an algorithm to monitor the network and see how long transactions take to confirm and then uses that to determine what fee is needed to get a transaction to confirm quickly. If it doesn't have sufficient information since it had just been started, it could be miscalculating. If you have the tx id, that might be helpful ;-) |
