i have my wallet encrypted on my pc..
i just changed this password.. i was wondering if i have to reback it up or if the backup i have, which is secure, is still ok with the old password.
Your question is not clear.

If you backup your current wallet, then the backup would have the new password.

If you want to restore an old backup created before you changed the password, then it will use the old password.

So when is a fork scheduled?
They are all listed on the site.

There is no "schedule" for forks, only the time when the forks can begin deployment and when it expires. Forks are not deployed at a set date.

Note that I was not able to see the thread in question before it was deleted.

Based upon the description of the thread in the other meta topic, it appears that your thread could have been deleted for being a duplicate post. If it was just a link to another thread, this could be seen as a duplicate thread and thus against the forum rules.

It was not though. I realize we are hampered here by not being able to see the post but. It consisted of a paragraph or two warning users about the use of aggressive self-moderated threads as a deceptive promotional tool by a particular coin community and one link to another thread. The bulk of the post was not duplication it was writing on a specific point, and given the topic being multiple, all self-moderated threads about a coin, I would think one post to with one link to one unmoderated thread would in fact be less duplicative.

But if the problem was the link I would be okay with reposting without the link and just suggesting that users view the unmoderated thread (which they can find on their own) to see the only unfiltered discussion on the topic here.

EDIT: Here is the post retrieved from google web cache:


Topic: Vcash -- warning about moderated threads, link to unmoderated thread

The Vcash cryptocurrency scammers frequently create heavily moderated discussion threads, pumping the coin by deleting all posts but their own hype. You can tell it is always the same dozen or so nicks, I wonder how many of them are actually sock puppets.

WARNING: many people have reported that messages are selectively deleted from the self-moderated threads based on expressing any criticism or questioning of Vcash or the claims of its supporters. If you are reading those threads, be aware you are seeing a very one sided version of the discussion that occurred.

Here is a link to the unmoderated Vcash discussion where you can get a balanced unfiltered perspective about the coin.

Hmm. It doesn't look like a duplicate post as the info in that post is not present in the linked thread; it is an entirely different subject. In this case, I'm not sure why this was removed and why it was considered to be spam. You will have to ask grue about it.

Bitcointalk will show you if a post was edited by underlining the time of the post with dashed lines. But it doesn't do show the edit history.

I am not aware that this can be done. Thanks!

Me either.  I just tested it and I'll be damned...  It works.  Now I may have to actually proofread my posts before I hit the post button instead of editing them all immediately afterward.

EDIT:  Just showing it works.  Umm....  I guess it doesn't work in every section.   Huh
There is a 10(?) minute grace period in which any edit will not show the dashed line.
6508  Other / Beginners & Help / Re: stupid question how created blockhain? on: May 25, 2016, 04:19:32 PM
sorry for my idiotic quexsstion but who created it?  bitcoin? if so why companys cann use blockhain for their needs e.g. ibm and other companys  shoudnt they pay a commision to have the right to use the blockhain
The blockhain was created by satoshi. Anyone can download the blockhain and anything can be added to it through bitcoin transactions. It is entirely public, so anyone can do whatever they want with the blockhain.
6509  Bitcoin / Bitcoin Technical Support / Re: Ubuntu and Bash on Windows 10 on: May 25, 2016, 04:18:14 PM
The has to do with an issue with binding to ports from the Linux Subsystem. Because Bitcoin Core can't bind to the necessary ports, you can't access it over RPC nor will it be able to accept incoming connections. This is a problem with the subsystem itself so you will have to wait for later releases to fix that.

It should, however, be possible to fix programmatically IMHO?
No, it's a problem with the Linux subsystem itself.

Is it possible to share my extended public key to an another wallet using the Bitcoin network ?
No. There is no way to share that over the p2p network.
6512  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: May 25, 2016, 11:42:18 AM
site, doesn't work.
No eror code but not working.

Yeah, looks like the whole website is down now. What's happening knightdk? Are you making an update to your website? For sure, many bitcointalk users will be unhappy if bctalkaccountpricer.info will be gone  Cry.
It should be working now.

The problem is a memory leak that I can't find. I think it has something to do with the databases, but I'm not sure. I'm trying to figure out where it is but it is difficult to do. Because of the memory leak, the server crashes every so often and I have to restart it manually. I'm trying to fix the issue, but as I said, it is very difficult to do so.

6514  Bitcoin / Development & Technical Discussion / Re: How to use the BIP-32 keys on: May 24, 2016, 11:39:19 PM
I am trying to built an application that uses the BIP-32. But I am not sure on how to use it.

I have a passphrase with which I generate the Derived Private Key and Derived Public Key. If I share my Derived Public Key with a second wallet will the wallet be able to generate others Derived Public Key from it ? Is it possible ?
No, it is not possible. The second wallet would need to have either the master public key or the master private key in order to generate other addresses.

Is there any issue in sharing my master public key with a second wallet ?
That other wallet would be able to see every single transaction to and from your wallet. If you give this to another person, then you will lose any transaction privacy. Otherwise, there are no security issues with sharing the master public key.

However, if you share the master public key AND a derived private key, then it is possible for that other person to be able to derive the master private key and thus potentially steal all of the Bitcoin.

No, it is not possible. The second wallet would need to have either the master public key or the master private key in order to generate other addresses.

And since I have the original Derived Private Key with me, can I see what is happening in the second wallet ?
If you mean can you see the transactions, then yes. This is with any Bitcoin private and public key. If you know one of those, the address can be derived and all transactions can be viewed by anyone.

Also if I loose both the Derived Private Key and Derived Public Key, will I be able to recover my wallets using only the Passphrase ?

Yes. So long as you don't lose the master private key, all of your addresses and the corresponding keys can be derived.
6516  Bitcoin / Armory / Re: Armory 0.94.1 is out on: May 24, 2016, 02:35:47 AM
I am not calling Armory a trojan, I am talking about a trojan running at the same time as Armory trying to steal bitcoins.

Thanks, I am trying to import now. I am thinking of how this could be possible.
I keep getting Invalid private key encoding (code -5) in bitcoin-qt console
I have no way to verify this is correct in bitcoin core.

I need to export my wallets in core to make sure my coins are stolen.

importprivkey is not working on the armory exports
It just doesn't make sense to me, I need to confirm in bitcore-qt

I'm working to generate payment in coins here.. have about 5..

Then one day armory just shows incorrect balances and the interface starts being buggy..

And so it's now a trojan or something that stole the coins but the interface is buggy so I can't tell

I want to export into bitcoin-qt core to see the balances there before I conclude someone must have trojaned my computer and stole  those from multiple wallets with passphase

But now I can't export to bitcoin-qt with any armory export?

Any ideas?
It works fine for me. You need to make sure that you are not missing any characters and don't have any spaces in the private key.

P.S. You should stop posting consecutive posts like you are doing right now. It is very spammy. Instead, when you have some information to add and no one has responded yet, please edit your last post with that extra info.

Been trying for almost an hour now but the "Request Queuing failed. Please try again." still persist. I'm using latest version of chrome, already tried to clear cookies and cache, but still it don't work.
Sorry, it crashed again. Should work now.
6518  Bitcoin / Armory / Re: Armory 0.94.1 is out on: May 24, 2016, 12:47:03 AM
So I guess this is some type of trojan that has been sitting calling bitcoind every 10 minutes or something trying to extract private keys?

I'm trying to port over to bitcoin-qt now to verify. I don't know exactly how it was done. I remember it was a day I visited a litecoin website and installed litecoin.
If you are calling Armory a trojan, then you are mistaken. It is not a virus nor is it malware.

No, I haven't done this exported and imported before

I am still trying to figure out how to export from armory to a format I can use in bitcoin-qt console for function

importprivkey

I tried PrivBase58, PrivHexBE, SHA256(?) format but it would give me the error:

Invalid private key encoding (code -5)
When you look at the Address key info, you want to use the "Private Key (base58)" or if you exported the key lists you want "PrivBase58", both are the same. You want to copy that string without spaces in order to import to Bitcoin Core. There is a handy little checkbox when you export the key list to "Omit spaces in key data". The key should start with a "5" (all uncompressed Bitcoin Private keys start with a 5). If it does not, then it is not the importable private key.
6519  Bitcoin / Bitcoin Discussion / Re: Should there be a GUI for Bitcoin core? on: May 23, 2016, 11:07:30 PM
let me add another noobish question (offtopic)
How can i proof this payment (and address) is mine?

Somehow the blockchain stores where money comes from and where it goes to. But how can you tell "this address is mine"?

I think thats all for me to start in bitcoin universe right now Smiley

Greetings Astrali
By virtue of having the private key. Whoever has the private key owns the address.  Everyone else can only know who owns an address because that person has the private key and can produce a valid signature for its corresponding address. If someone were to steal the private key, then that person would also own the address even if he really didn't. There is no way to tell. This is why you should always keep your private keys safe and never reveal them.
6520  Bitcoin / Bitcoin Discussion / Re: Should there be a GUI for Bitcoin core? on: May 23, 2016, 08:15:35 PM
hi - i just registered to leave some words here, just because i am quite new to bitcoin and decided to get a full node wallet.

as i am Computer user for Ages (started with DOS) and would not call myself the default noob i am still confused with the bitcoin core gui and what to do ..

When i start bitcoin core and go to the menu theres an Option to show my addresses to receive payments (there was 1 present and i created a second one).
This is where you get your receiving addresses.

now theres also the Option to "receive payments" which will generate a new address (i already understood why) but i need to declare the value incoming on this address .. for me this is confusing!
That is for the BIP70 Payment Requests, which are files that you can send to someone and their wallet will automatically understand the file and send you the right amount. The original goal was to use these payment requests to deprecate the traditional address stuff, but it didn't really catch on.
