Does anyone know what is going on? In the past few weeks (months) the network has been working slower and slower. But today UNCONFIRMED TRANSACTIONS have reached a new HIGH for me at least:
https://blockchain.info/unconfirmed-transactionsIt is obvious this is no accident, I guess someone is doing this on purpose, but what purpose is that  This is as of the moment I am typing this message, and they are getting more every minute: There are just more people moving their coins round. I don't think anyone is doing this on purpose or it's an attack. If someone want to spam, they can doing much better than 7000 transactions  Their purpose is to stress test the network. In addition to the links above (shorena and amaclin's), here is more of a discussion and analysis: https://bitcointalk.org/index.php?topic=1075590.60 |

Monetary policy, used responsibly, is useful to manage public finances, provided it is not abused to issue too much currency. Greece cannot itself use monetary policy whilst it is part of the eurozone and adopting bitcoin would put Greece in exactly the same position.
...
[/quote] Monetary policy is something that should never be put in the hands of people. They will use it to enhance their own power, nothing more. It cannot be "used responsibly". Deflating the currency hurts the poor, and helps the powerful. It is a tool to obtain and retain power. Consequently the authoritarians in power in Greece (or elsewhere) would never go for it. |

I recently had to format my laptop due to some serious virus issues, I did manage to backup my files and folders but now although I can find things relating to my nxt wallet I can't reinstate it and god knows where the bitcoins have gone to, help  Is this an nxt wallet or bitcoin? As others have said: what OS, what software etc? :-) |

sudo: unable to resolve host ubuntu
wget: unable to resolve host address `samba.org'
wget: unable to resolve host address `bitcoincore.org'
Two questions: 1. Can you specify which "first command" you are running? 2.Can you ping those hosts from your server? e.g. ping samba.org ping bitcoincore.org :-) |

What version of Bitcoin Core are you using?
This. What version is it? What are you intending to do with it? If it is just something like extract the private keys, then you probably are fine. |

He probably could have sent the money for free. Might have taken a bit longer but the fee is always worth it to support the miners. I also think charities are missing out not accepting bitcoin but I'm sure more will get involved over time. Where is the link? I want to read the rest of it.  You could just google for it: [Suspicious link removed]j.com/articles/here-comes-almost-free-money-1433715790 edit: damnit it's not showing up. Just google it then lol.  good article! Yeah, it was good. I posted it above, but if the link above only takes you to the pay-walled version, search with "Money Isn’t Free, but Moving It Is Now Cheaper" in Google and follow that WSJ link, it should give you the full article. |

1) Irreversibility, ie if someone sends to an incorrect / dead address / loses keys then its gone. Or people injection malicious stuff into the blockchain leaving it there forever.
2) Theoretical anonymity. While we all like privacy, there is a problem when something goes from 99.99% untraceable to 100% untraceable (TOR based tumbling). There ARE cases were its important that criminals are traceable even with great efforts, else it makes Bitcoin users a target. Imagine how attractive users are when the goods they take are untraceable, unmarked 'bills' with no risk of ever getting caught. I don't like it.
3) Vulnerable to attacks. With no central body that can react quickly, things like transaction floods can temporarily damage the network. Because it takes a community effort or dev census to nullify the attack, its much slower than someone who can implement needed changes instantaneously. Ie Theymos pulling the plug on the servers when he noticed the intrusion.
I would argue that each of these is a feature, not a point for criticism 1. Irreversibility is a feature. You can safely ship a good, knowing that you will be paid and not defrauded. 2. Anonymity is also a feature. Eg. My landlord doesn't know I got a raise. 3. It is a dynamic system and much more resilient to attacks because there is not a central authority to attack. |

One day last year, at the height of the Ukrainian revolution, Mark Howard spotted something interesting on television. In the background, a protester was holding up a poster with an instantly recognizable logo: A “B” with two vertical bars, the symbol for the digital currency bitcoin.
Mr. Howard is an American IT specialist and a self-described bitcoin enthusiast. He surmised that the poster’s QR code, which is a kind of square bar code, must contain the address of a bitcoin wallet belonging to the protesters. On a whim, he froze the frame, scanned the code with an app on his phone, and sent $10 worth of bitcoin to a country whose banks were paralyzed but whose protesters needed money to continue their fight.
It happened instantly, and the total cost of the transaction was $0.02.
If using unregulated cryptocurrency to crowd-fund foreign revolutions sounds...

People seem to think it has to do with the wallet version or OS?
That is private information I think.
It must have been some kind of hack trick to put that message into my wallet
like that.
...
Of course it has to do with the wallet you are using and the OS. If you are running Windows 7 you are much more likely to have a virus and a "hack trick" than Windows 10 beta, Ubuntu 14 or OS X. It is just reality. If you are running Bitcoin 0.3.21 or some other wallet you are likely out of date. etc. Without any of that information, don't expect anyone to be able to help you here since there would be too many variables to have any hope of doing anything except guessing. |

What wallet? What version? What OS?

actually I want to compile a OSX version of wallet, I have ubuntu server not not a mac yet
If you look at the gitian compile discussion it shows you how to build Linux, Windows and OS X on one machine. Perhaps that would be a good place to look too. It doesn't need mac ports, btw. |

is there RPC API for making blockchain of altcoin, Not blockchain.info, I means to get info from wallet (Ubuntu Node)
a. This section is for bitcoin, not alt coins. [Someone moved it to the correct area] b. RPC API calls aren't for "making blockchain". c. You may want to ask that again because it is very difficult to understand what you are asking. |

You don't need to do anything, I know many altcoins were forked, and there were no hazard for fork actually, sometimes a coin is forked when it has new significant feature updated or parameter changed, like if btc's block time changes to 1 minutes, there will be a hard for. So you just need to upgrade your new wallet and your money won't be lost, take it easy. Fox, he's talking about the "gavincoin" fork. Ie, the situation with block sizes and the potential hardfork in the network. Under this scenario, bitcoin forks and there's a (potential for) a situation where those who don't upgrade are on an "altcoin". And he'll have coins on both forks - as would everyone else who had bitcoin on the bitcoin chain at the time of the fork being discussed. |

This is likely the most important part. HOW did you "move them to a different computer"? Did you copy only the one private key or the entire wallet.dat? Also, do you still have access to the old computer? If so, (and if what you are saying is accurate), then in all likelihood all the private keys needed to access all your BTC are in there. You can export ALL the private keys from there and import them elsewhere. Likewise for Litecoin (Lite not Light), you should copy your wallet.dat over. The good news is that it seems extremely unlikely you got hacked since the coins have not moved in 18 months. ;-) |

If you are talking about proposals regarding block sizes, you might have to update Multibit, but the addresses won't change.
That's gotta be the one he means. FWIW, OP, you'll probably want to update Multibit several times between now and the date when the hardfork happens on block size. Anyway, good points cr1776 about the fact that there are little forks all the time. The version i use is the same version available for download on their website, will multibit let me know when i need to download the new version? You said the addresses won't change, i will have to import my wallets from the old mulitibit version to the new ones correct? thanks The odds are that there will be quite a long period before it happens. So no doubt Multibit and others will have several updates between the time any block size fork is announced and when it occurs. Then there may be some time between that and when you will see a super large block. I haven't looked at Multibit's code, but a change to support larger blocks shouldn't be a difficult change, so it probably isn't something to worry about. Bitcoin Core's changes to support a larger block are relatively minor. If you are concerned, always make sure you have a backup of your private keys (you should always do that anyway) and then you can use any wallet software that you wish. Once a proposal is settled upon, people will be able to give you better advice. All of this is assuming something happens with regard to block sizes. ;-) |

I use multibit, will i need to update it? can i still keep my old btc addresses?
Any input appreciated
Which fork? Forks happen daily when blocks are orphaned and the chain reorganizes. You shouldn't have to do anything immediately, depending on what you are asking. See e.g. https://en.bitcoin.it/wiki/Block_chainhttps://blockchain.info/orphaned-blocksIf you are talking about proposals regarding block sizes, you might have to update Multibit, but the addresses won't change. |

Thank you. I definitely rushed into it in an effort to get my business back up and running and obviously made a bad decision. I appreciate your input and am looking into an alternate wallet. This has been quite an experience.
Thanks again.
On thing to consider in the future is having backups that are done automatically. e.g. like Time Machine for Mac OS X, so that you don't have to pay in the future. And don't have to panic. Perhaps it can be impetus to implement a continual backup strategy. Your decision to pick Bitcoin Core wasn't bad, just the way things go when rushing. Danny gave you good advice. Good luck. ;-) |

how can we impliment offline payment without the blockchain, at least we can check if the coin is valid if the blockchain on the sellers computer is recent we can ensure no double spending until the last time the blockchain was Synced.
You can just have a database that you sync with when you would be syncing with the block chain. If you are worried that someone could corrupt the database on the computer, they could do the same thing with the block chain stored on their computer. Your "check to see if the coin is valid" would not be foolproof. It sounds like the customer just wants to be able to use a buzzword of "block chain" without understanding the benefits and drawbacks. And this is pretty off-topic for here, it should be in the alt-coin section. |

Activity is updated, the update day (as of today) was the same. And this really belongs in the "Meta" section.
