Thanks, will check it out. But looking at it so far, it looks like this wallet interacts with web and is open on a port even if used behind the scene with PHP. I will look deeper, I assume there is a way to secure that.
Well it still must be able to connect to the internet in order to get transaction details. Electrum connects to Electrum servers which do the address lookups and provide the client with the necessary transaction information so that you know how much Bitcoin you have and can then send the Bitcoin. Adding to my request is. I only have xPubx given to me. I need to be able to use those to create addresses. I noticed many wallets (like copay) you need to create the watch addresses using the private keys.
Electrum allows you to import a watch-only wallet using the xpub. |

The server=1/RPC cookie issue
If the absence of server=1 can be detected, why not get Armory to produce an Error dialog box to tell the user how to deal with the issue? As I said, there'll be infinity threads about this if it's not handled at the software end somehow
Since the RPC stuff is now handled by the DB side, I imagine there's something that makes it difficult for an error on the DB end to trigger an error on the client end, although I am not sure. I can take a look and see if I can do anything about it this weekend. |

You can use an Electrum wallet for this. Install Electrum on the server and put a watch-only copy of the wallet onto that install. Then you can interact with it using the JSON-RPC interface. See http://docs.electrum.org/en/latest/merchant.html |

achow? really? why? im stressing i just lost a lot of money, and you're correcting my grammar. not nice.
I'm not correcting your grammer. If you actually started entering "aweful" into the seed recovery, it will not recognize that word and correct you to the only word in the wordlist that begins with "awe", which is "awesome". "Awful" is a word in the wordlist, so it should recognize that you are entering "awful" if you spell it correctly. |

|

another weird thing, happend twice, i write down the seed words, begin entering them, and one of the seed words is wrong, i have it written down wright, the word is aweful, but it wants me to put in awesome, which sketches me out. wtf is that about? so i stopped there.
Aweful isn't a word. You have spelled it incorrectly, it's awful (no e's in the word) |

One does not simply "copy a computer chip". Doing that is practically impossible and requires extremely specialized equipment in order to figure out the exact circuitry of the chip and then you have to fab the chip, which is expensive and time consuming. Thank you so much for your reply @DuddlyDoRight, what do you mean by "buy the IP"?
IP means Intellectual Property. He means your only option is to literally buy the designs for the chip from the current owners of the designs. That's not likely to happen. as well as "Just hire an FPGA dev"?
Hire someone who knows how to program Field Programmable Gate Arrays, devices similar to Application Specific Integrated Circuits (i.e. ASIC chips) but a bit more general purpose. No, we don't have the blueprint of the chip @Senior.bla. But the person who wants this job done is a co-developer of the chip but his business partner took all the rights of the chip. and he felt that this was unfair for him and he wants to become independent because of his partner's business practices which was unfortunate.
You and him will be violating copyright laws if you attempt to copy the chip exactly (or even similarly) and attempt to sell it as a product. Given that you have exhibited a clear lack of knowledge, I suggest you first research how chip production is done and how developing Integrated Circuits (i.e. chips) works before you try copying someone else's chip (which is illegal) or attempt to make a business selling computer chips. |

All of Bitcoin Core's data files are completely Operating System independent. You can copy/move all of the files over, including the blockchain block files and the wallet.dat, without worrying about any incompatibilities. If you use the latest version of Bitcoin Core, you are unlikely to run into any issues.

IIRC Armory does not do anything with checking the validity of the blocks it receives, it assumes that Core did that. Since Armory will only connect to the local Core client, it will accept whatever Core gives it. However, since it does use a p2p connection, it will be checking for the magic bytes, so if you change those in your private blockchain, you will have to change those in Armory as well.

Your wallet should be set up with the Ledger now, so it will be displaying whatever the balance of your Ledger is. Electrum supports multiple wallets, but does not show multiple wallets in the same window. If you go to New > Open, you should be able to open your previous normal Electrum wallet.

Segwit essentially introduces a new transaction format. It introduces a new transaction format which is just the current one but with 2 additional bytes signalling that it is the new format, and the additional witnesses field before the nLocktime. When a node connects to another node, it tells that node that it supports segwit. So, that other node, if it also supports segwit, will send transactions with the segwit format. When it goes to send a block, it will send the block with the transactions also serialized in the segwit format. If a node does not say that it supports segwit or if a transaction does not use the witnesses field, then the transaction will be sent with the original format without the witnesses field.
The merkle root of the block header contains the hash of the txids. There will be an additional merkle root of the hashes of all the transactions in the block which will be put in an OP_RETURN output of the coinbase.

Check that the transaction does not spend from any other unconfirmed transactions. Check that the transaction is final, I.e. the sequence number of the inputs are all Max sequence and that the locktime has passed.

Thanks, extracted the tgz and now have in a folder but what do I do with it?
Do I just copy the files of the different folders (bin, include, lib, share) to the corresponding folders in my root directory?
You can do that. You can also just run the binaries directly from the folder they are in. You can also add the path of the binaries to your PATH so they can be run from anywhere. |

Hi I installed this version adding to the repository packages and then sudo apt-get install bitcoin-qt But then I read that it's safer to install directly using the Linux TGZ found at https://bitcoin.org/en/download, which I want to install instead. I'm running latest version of Lubuntu (instead of just Ubuntu because wanted to have better performance as Lubuntu is a lighter ubuntu flavor). Surprizingly I've been looking around all over the web and I cannot find anywhere HOW TO INSTALL the Bitcoin Core tgz. Can anyone help please ? Thanks The archive is not something you install in the traditional sense of "install software". Rather it just contains the binaries that you run, so just extract the archive to some place and add the path to wherever you extracted it to your PATH environment variable. |

Typos, especially just comment typos, are generally very low priority and don't need their own pull requests for every single typo, especially one character ones like this. These are usually batched into big "typo fix" PRs. There really isn't any need to fix typos anyways, the comments are generally understandable.

Does this mean nobody used signrawtransaction to sign multisigs like this for 18 months?
I don't think people use Core for Multisig. There are much better software for multisig. |

It's possible that someone got their hands on the old hacked database from May 2015 and decided to actually attempt to get into accounts with info that they gathered from that database.
Another possibility is that some site Bitcoin related was hacked and people got their hands on their databases and are checking to see if there are reused passwords to get into bitcointalk accounts. For example, recently a database dump from 2014 of btc-e's database reached HaveIBeenPwned so it is likely that that database was floating around publicly for a bit of time beforehand and is still available. So people might be using that to match accounts on btc-e to accounts on the forum and then trying passwords to see if there is any reuse.
Unfortunately the forum can't really do much. If the admins lock accounts which have not changed their passwords and then send password reset emails to all of those accounts, a lot of people will be locked out because emails aren't validated and a lot are either invalid, or just point back to bitcointalk.

Please do not make duplicate topics. Blockchain.info has removed your transaction either because it was unconfirmed for too long or its fee was too low. See https://bitcointalk.org/index.php?topic=1802212.0 for what you can do about "stuck" transactions. |

Are you using the latest version of Electrum? The latest version handles fees differently.

That is a known bug that has been fixed in 0.96. If you can't build 0.96, you will have to wait for the testing builds to be released.
I have never heard of Manjaro. The only linux distros that Armory currently supports are Debian/Ubuntu. Anything else may not necessarily work.
