Hi,
I am currently running a full node, and running out of space. For technical reasons I many not be able to upgrade to storage for a while.
1) If I have some more space on another partition, is there a way to tell Core to concatenate another chainstate folder(s) to the current one?
(So it will use the space I have on another partition).
2) What are the consequences of using pruning? Will that impact my ability to send/receive txs, or it just means I can't fully verify everey tx?
3) What does the 'n' in "prune=<n>" stand for, and what is a good configuration to use?
Many thanks!
Here is some info on pruning: https://github.com/bitcoin/bitcoin/blob/v0.11.0/doc/release-notes.md#block-file-pruning"N is the number of MB to allot for raw block & undo data." And https://bitcoin.org/en/release/v0.12.0#wallet-pruning |

24c0e3543b02442bbfb0e5f117029f921ffa41aed9fb3f32078b2552dfa79274 this is the offending txid  As knight said, that block was orphaned, so you would have to contact blockchain.info support if you were trying to transfer from the old blockchain.info wallet to the new one. |

I have the seed words. Honestly, I don'r even remember it asking me to set up a password initially. I only discovered this when went to move some of my btc and it asked me for a password.
Yes, as long as you have the seed words, you are fine. Glad you got it figured out! |

I recently installed an Electrum wallet. In trying to access it, I discovered that I have misplaced my password. I have the private keys recorded but for some reason, the password wasn't with them. How can I re-access my btc?
If you have no password you are screwed up, try to remember it very hard! Do you remember anything about it like 1 or even more letters? if yes you can try to brutforce it, just wait more experienced members will explain on how to do it! If he has the private keys, then he isn't screwed. As far as "password" do you mean the seed list of words? He can import the keys, and then send them to a new address created in a wallet he has the word list for. Moving this to the Electrum sub-section, might be useful too. :-) |

If indeed there is "currency changing hands for people sharing files" the next level "decentralization, anonymity & encryption" will be a must. And if indeed it is using bitcoin, his hyperbole will be completely justified.
Between the halving having been shaken out for 6 months by then, COIN, use cases like this, seg wit deploying, and perhaps sidechains, 2017 could be a banner year.

This is like saying that a bank was robbed in the EU while in the US someone managed to get the Fed to "quantitatively ease" a cool billion $ in their account and yet both the dollar and the euro are to blame. In fact, one is just a bank having poor security, the other is the system behind the currency was the problem.
When you get articles like this posted I always wonder what else in the articles they got wrong,:-)

..."address using `addmultisigaddress` command then that address is attached one particular account which is saved in wallet.dat file"...
Just a quick note since not at a real keyboard, but I'm not clear if you are talking about Bitcoin core accounts or not, but Bitcoin core accounts may not work how you think, and they are deprecated and will be removed relatively soon.

Their FAQ has some explanations about the disparity you see which it sounds like Jhanzo was referencing, particularly the bold portion below: https://support.xapo.com/why-can-t-i-see-my-wallet-balance-on-a-blockchain-explorer/view=faqWhy can't I see my wallet balance on a blockchain explorer?
Xapo protects your privacy by keeping your wallet balance and your wallet transactions private so no one can see them in the public blockchain. You can use your Xapo wallet with the confidence that no one will know your wallet balance or your wallet transactions.
Xapo uses dynamically generated wallet addresses. These are public addresses meant to be shared with anyone you'd like to receive funds from. While you can use the same address multiple times, if the address remains unchanged, anyone you transact with could know the amount of funds you have by simply using a blockchain explorer. We implemented a two-step solution to avoid that from happening.
Each time someone sends bitcoins to your address, a new wallet address will generate, replacing the old address (you will see it by clicking "My Address" button in the web app). This ensures that the person to whom you've sent funds will know only one address, corresponding to a single transaction.
If someone sends funds to an older, previously generated address, you will still receive those funds to your wallet, as we keep all bitcoin addresses ever associated with your account available, just in case you ever plan to reuse or receive ongoing payments to a single address.
The second step involves pooling your wallet funds. As soon as funds arrive to your bitcoin wallet address, we move those funds to a common pool. This prevents anyone from going to the blockchain and seeing the amount of BTC in your addresses or discovering where your are transferring them from. Since the funds are pooled amongst other individuals funds, it is extremely difficult for someone to identify specifically where the original funds that you received were sent from. |

If for some reason -upgradewallet doesn't work, the source for the older versions is available. Likewise, pywallet is an option to extract the keys if needed. E.g. these are links to the pages where various versions are available: https://github.com/bitcoin/bitcoin/tags?after=v0.3.23https://github.com/bitcoin/bitcoin/tags?after=v0.5.0rc3so you could download, compile, then send to a new address. Or go version 0.3.x to 0.4.x (which, iirc is where the format changed). Whatever you do at this point, make a few backup copies of your wallet.dat just to be safe. |

I am not dismissing concerns about bandwidth or disk space. I am merely pointing out that arguments that don't take into account exponential increases in capacity in both bandwidth and storage space with stable or decreasing costs are (a) purposefully avoiding reality, (b) purposefully trying to mislead people, OR (c) trolling. If you or anyone wishes to code the "distributed file system" and integrate it with Bitcoin Core and convince people it is a better solution so that a majority if people adopt it, please go ahead. Is there a technical paper of how this would work in bitcoin and an analysis as to how it would provide the same security that Bitcoin does now? I am sure that any well-tested code that the people who are complaining about the block chain size (and the like) are willing to commit to Bitcoin Core to decrease the sizes would be more than welcome. Danny is right, and that is just the average.
xfinity runs at least 88 Mbps right now or 8.8 MBps => 528MB/minute = >31GB/hour => 744GB/day.
AT&T Fiber (GigaPower) 300Mbps = about 2.5TB/day.
In 1980 one was lucky to get 300bps (or 180bps). No one serious thinks this has peaked.
So now bandwidth is being dismissed by the same flawed arguments as the disk space?  Completely ignoring data caps and low speed restrictions imposed by providers. Completely ignoring that only first world countries have these sorts of high speed infrastructures (the US is hardly the worst performer in the world). Completely ignoring that most people want to run more than just one application that sucks up all their bandwidth. Completely ignoring that while writing a technology cheque way into some mythical rose-tinted future, the only ones that are likely to be able to afford it are corporations, governments and fat cats. Bitcoin wasn't around in 1980 and has gone from zero to datacenter in a couple of years (let alone 40) due to the resources required to run the system and we are supposed to believe the tech available to the average Joe will be good enough in another 10 when it's struggling now? Makes my blood boil! |

How do you download tons of Gigabyte?
... According to speedmatters.org, average USA broadband speed is 11.7 Mbps. ... Danny is right, and that is just the average. xfinity runs at least 88 Mbps right now or 8.8 MBps => 528MB/minute = >31GB/hour => 744GB/day. AT&T Fiber (GigaPower) 300Mbps = about 2.5TB/day.

The question will be whether this was a "hack" or an inside job with "hack" as the excuse. ;-) All too often it is the later while blaming the former. One hopes that as part of their business they included insurance for this type of event. |

One question, you also had said previously that you had imported some keys. Was this one of them? definetely he used compromised private key. no doubts Obviously. The question is (and was) where he got them and why he imported them? |

I don’t know if the is the right list, but I hope someone can advise.
In the early hours of this morning I sent 1.01 BTC from my Xapo wallet to the address 12iocUthp58E72ZksRmToDFPfM1WCPKv91. This is an address in my Bitcoin Core wallet, running on my laptop, for which I control the private key. My client had been running all day and the blockchain was synced and up-to-date.
The instant that this amount was received into the above address (before the transaction was even confirmed) the entire amount was then sent to another address 1aa5cmqmvQq8YQTEqcTmW7dfBNuFwgdCD which I have never heard and do not have the private key for, something which I did not think was possible.
What the hell happened and where is my Bitcoin?
One question, you also had said previously that you had imported some keys. Was this one of them? And as DH asked above, where did those keys come from? |

...One option is to switch to Ethereum which has an impeccable development team and has announced plans for unlimited scalability...
"impeccable" - in some random persons opinion. In that same way, "the Fed has a impeccable leadership team," assuming you believe some random writer at the NY Times, like perpetual inflation at the whim of a random person who happens to be appointed at this point in time. Rules that can be changed on a dime are not rules. Rules that can be changed when someone doesn't like the outcome of the rules, aren't rules and set terrible precedent going forward. The "easy" solution in the short term is often a bad solution long term. "unlimited scalability" - let's see how that turns out. Bitcoin could have unlimited* scalability (and did for a while and was hit with spam) but with unlimited scalability the block chain would be in the multi-hundred TB range by now. There is a cost to everything, someone will pay it one way or another. TANSTAAFL. *no such thing in reality |
