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. |

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. |

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. |

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  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. |

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. |

bump.
is it ready yet?
It is still being reviewed. It's going a bit slowly. The code exists, the PR has been submitted, and AFAIK, it works. However, people are still reviewing it to make sure that there are no bugs and that it is optimized. |

Any coming updates for this App? How was the experience on using this? Any plans for iOS?
Btw Dev, if you are still active, you had experience on making android wallets?
Thank you.
This project is pretty much dead. I have stopped working on it due to my inexperience with and lack of care for GUIs. |

Just wait some minutes and try again...
Request Queuing failed. Please try again.
Actually there is this message probably to many people try to use it in the same time  I can't use the site. The site takes longer to load than other sites such as this one.
I can't use the site. The site takes longer to load than other sites such as this one.
Just checked the site and it is taking long (or not loading at all), probably someone is DDOSing or the server is not able to serve all the requests made. Sorry guys. The software has a memory leak somewhere which crashes the server eventually. It should be working now, at least for the next few hours. |

Good luck with your project. Seems like a cool idea but why would we want to monitor blockchain forks for?
There will be some forks in the future to roll out new features such as Segwit or a larger block size. These all require forks. The point of the site is to monitor blockchain so that we know when/if a fork is going to happen. |

My questions:
1.a How long does it take to verify the validity of a single transaction (not included in a block)? I guess some assumptions must be made (CPU, memory, number of inouts/outputs in a transaction)
It depends on the number of inputs and signature operations. A transaction could theoretically take several minutes to verify. 1.b Is there a tool available with which I can test and observe the verification time (of a single and/or multiple transactions)?
I'm not sure, but you can probably write one. 2. Is transaction validation of a single transaction (not included in a block) similar to transaction validation of a transaction in a block body?
Thanks.
Yes. |

Is there a way to create zero fee transaction anymore.The only way I knew was Blockchain.info and it seems they have removed it now.
PS: I need it for technical purpose.
You can create it by hand using Bitcoin Core's createrawtransaction RPC. |

(Note, I'm not sure, but I think you might need to have txindex=1 set in your bitcoin.conf if you want to be able to run getrawtransaction for transactions that weren't sent to or from your wallet).
That is right. You must either have txindex=1 in the bitcoin.conf file or have -txindex in the startup command. Otherwise you cannot see transactions that are not in your wallet. Using the txindex will require that you also reindex the databases, which can take several hours. |

You earn trust by doing trades or providing services. DO NOT ACTIVELY TRY TO GAIN TRUST BY CONDUCTING TRADES SOLELY FOR THE TRUST! If you are a trustworthy person, then your actions on this forum will speak for themselves and you will earn trust. However, if you actively seek trust and attempt to do reputation trades (small trades solely to earn trust) then you will earn negative trust.

Uwh ,somothing like that,so is unity there.. I hear it can make us do not need a third party ?
Sorry, but your question is incomprehensible. The way that Bitcoin is designed makes it so that you do not need to depend on any other party to do things and that, in theory, you can take matters into your own hands if you don't like something. |

I have some question although I have learned I always go back to newbie and rotates around over there.and now this is my question :
What does it mean by Bitcoin is Decentralization ,is decentralization only in working system along payment system or all about Bitcoin is decentralization ?
very thanks for answer..
regards ,
Your question is hard to understand. What are you trying to ask? Are you asking what is decentralized about Bitcoin? If so, then the answer is everything. Everything about Bitcoin is decentralized as there is no central body which issues Bitcoin and adds to the blockchain. It is entirely peer to peer and does not rely on any one server(s) to do anything. thanks, btw I changed the use of wrong word ,google does not always give the correct word. that only p2p system makes Bitcoin decentralized ? The p2p system and the proof of work system are the primary aspects of Bitcoin's decentralization. P2p make it so that no block or transaction must originate from a central controlling server. The proof of work system makes it so that each node will only accept blocks that prove an amount of work was done. |
