I could miss $2 a month to support the network. But to me it looks like centralization of bitcoin nodes. Do those nodes share the same ip address? Of so, what's the benefit of running them?
Wouldn't it be better for the network if the nodes are geographically spread around the world, all using different hardware and ip addresses? Or are vps' considered "better than nothing"?
In other words, what's better? A low end home server running a node or a shared centralized node on high end hardware?
Here's the IP address on one of my VPS nodes: http://192.227.139.229/ It doesn't look shared to me. But I'm not the expert on these things. [...] 192.227.139.229 is at ColoCrossing https://getaddr.bitnodes.io/nodes/?q=colocrossing. 45 nodes at that DC. If they have a power outage or worse, that's 45 nodes gone. Just an example of course and who knows how accurate bitnodes is, but different geographic locations help for sure. If you can miss 2$ a month and plan to run a node for two years, you are getting in to Raspberry Pi territory (with an external HDD), if you're internet plan allows for it.

I want to know which bank you are using so that I make my calculations and then to decide whether I am wiring you money or not.
Maybe I don't like your banks or maybe I have bank accounts in the same bank and maybe I am using the same payment processor.
I want to know all these infos prior to verify my account with you, [...]
...which will save me the time to send my docs, if I cannot or don't want to use the banks you use. [...] Our team has decades of experience in commercial banking and investment banking sectors.
Some names and CVs would help. |

My tests didn't agree with this, latency was worse for .kr than .sg, but anywhere closer than US is an improvement.
Well, where are you? And which servers did you ping in .kr and .sg? |

How about overvolting? Any drawbacks for (extreme) example: 800@970 ?
Edit: Apart from temps and power draw?

Yes. There is only one way to find out. Remove Armory and re-install (or set it up on another computer). Then import your backup. This is actually what they recommend to do. Read the "I'm scared" section on this site: https://bitcoinarmory.com/about/using-our-wallet/ |

While I'm at it, another simple request. Bulk import keys into an encrypted wallet.dat from csv. You may need the the private keys to derive the public keys, but the private keys will not be in the new wallet.dat.
I'm trying to create a watch-only full node, using Bitcoin Core. It's on the internet, therefore I prefer it to not have any private keys. All imported keys will be reserve keys or part of the pool. Core will not know the password/passphrase (I give it a dummy one at the start, when first creating the empty-wallet.dat) so it can't create new keys, and will use existing keys as needed.
I'm trying to import 5000 to 10000 keys, where the result will be a wallet file that only has public keys and bitcoin addresses, and the private keys are nuked.
If hackers steal the file, privacy may be lost, but no bitcoins will be lost.
Have you looked at armoryd? |

Here's page with some more info and another demo: http://point-at-infinity.org/ssss/index.html IIRC, you will see different results for the "shares" value, both solutions work as advertised though. ssss is in the Ubuntu repository since Trusty. The way it's implemented on bitadress currently, it will generate a private key for you. For us who like to generate our own private key (outside of bitadddress), but still would like to split it using their site, there is a fix described here: https://bitcointalk.org/index.php?topic=43496.msg8041834#msg8041834 |

I think OP had registered in Blockchain.info, a wallet identifier " f54a0bf0-6839-460a-9980-0f08cbd7d175" was emailed to him, now i hope he does remember the password he uses when registering.
Only blockchain.info has no support for multi sig. And that's the address the funds are currently in. |

One thing I don't see answered: Have you ever created an account at blockchain.info and if yes, can you still access it? And if you can access it, is the 35mYvUjMqiAYeobVhLc85PtHCmZKGeZ9Bi address somewhere in there? If not, by chance did you look at this link and picked any from those? https://www.expresscoin.com/wallets If yes, which one? Some of those support multi-signature transactions. My guess is maybe you created a wallet at BitGo too? |

You have two outputs, maybe from change?
One of them is 0.00000438 BTC and thus below the dust limit, which makes your TX "non standart" and bitcoin-core clients >0.9 will not relay it AFAIK.
Edit: Which wallet did you use? Did it not warn you about this?
I used blockchain.info wallet and it didn't warn me.. But had I other option? If I wanted to send exactly that amount there was no other chance to do it without this problem, right? It depends what is available to the wallet logic to choose from to begin with. blockchain.info has the "Custom Send" option where you can select the addresses the unspent outputs are chosen from. Another option could have been to export the private keys to another wallet software which may chosen differently since it may have been programmed differently, again, also depending on what would have been available to the wallet logic to choose from to begin with. |

I'm fairly active in Technical Support and the big majority of "Help, it takes a long time / what is wrong with Bitcoin Core" problems in this section are usually resolved after they waited for the sync to finish. Things like the bootstrap.dat, peers.dat and connect= may make it quicker, but the bottom line is you just have to wait. So I stand by my comment: Download, double-click, wait, done. ;-) Also, maybe people should just read? https://bitcoin.org/en/choose-your-walletBitcoin Core is a full Bitcoin client and builds the backbone of the network. It offers high levels of security, privacy, and stability. However, it has fewer features and it takes a lot of space and memory. The general clicky-clicky-give-me-ze-coinz-now attitude of people towards bitcoin has ended in tears a many times in various shapes and forms. Bitcoin is not easy. At the very least make an attempt at reading, trying to understand the basic principles, the risks involved with the different options that are available and then make an informed decision. This may mean that a light weight solution is the one for you. Or use something like Circle, if convenience is the most important (*shudder*). But it's more fruitful to go through that process first, before jumping in to something you don't understand and becoming frustrated. Regarding Satoshis post (if it's the one I'm thinking of) on that not everybody will run a full node: note how he talks about "generating" in there. So he was talking about mining. We are already at this point. Now, a bitcoin node without mining can be run on a minimal budget and resources using a RaspberryPi with an external hard drive (not saying *that* is trivial to do, but it works). |

I really don't have experience with those offline wallets but if somehow my PC get burned or something & I can't fix .. does it mean I will lose all my bitcoins unless I took a backup ? if yes how to take a backup
Shutdown bitcoin core. Then find wallet.dat, and copy it to a usb drive or two, store those at the office or another location you see fit. Make sure you've sett a passphrase on the wallet. Also realize that once you do transactions, change might be sent to new addresses in the wallet, requiring you to do a new backup. So each time I use my bitcoins (Send/receive) I have to take new backup of wallet.dat ? should I use Export & Import options or just find the file manually on directory ? Every 50 transactions or so is the recommendation. You can use the export in the program or do it manually. If you do it manually shut it down first. |

This has been asked before in this thread, but it wasn't fully answered: Does the Chain UP/DOWN work out of the box on the Habanero?

Hi Newar, I might be getting somewhere (Maybe!~) Just got an email from express coin containing the link to my wallet with Block chain (I didn't know I had it). Inoticed two difference bit coin addresses as follows: express coin 35mYvUjMqiAYeobVhLc85PtHCmZKGeZ9Bi and for block chain it is f54a0bf0-6839-460a-9980-0f08cbd7d175. Does that shed any light???  The first one is what is generally called a bitcoin address. A multi-signature one in this caae. The second starting with f is a transaction ID. You don't have walleet at blockchain, I don't think. Unless you made one. blockchain.info is also a block explorer site, showing what is happening on *the* blockchain. If you wish, you can double check for example on btc.blockr.io Wrong info, sorry, see below. If I understand you correctly the next step for you to do is a transaction from your Expresscoin account to your Bitcoin Core (Qt). To do this select "Receive" in Bitcoin Core and it will give you a address starting with a 1. This address you copy and paste in to your sending page at Expresscoin (I don't know that site, so don't know it's setup and process exactly). Then authorise the transaction and it should show up in your Bitcoin Qt shortly afterwards, depending on how soon blocks are found. If you are unsure you also can do a test transaction of e.g. 0.01 BTC so see how it works. You will have to pay the miners a small fee every time you do a tx, but in this case, take it as a "tuition fee" for your first bitcoin lesson  |
