Why can we generate bitcoin wallet offline?

When I generate a bitcoin wallet using a software, how does the software know that there is nobody using my wallet (same numbers and characters ?)

Qvault is now able to generate bitcoin wallets within the app

We just enabled a new feature in Qvault: Bitcoin wallet generation. It is the first password manager that can generate an HD wallet within the manager.
Qvault simply generates a new seed and the appropriate extended public key (xpub). That xpub can then be imported into a watch-only wallet to view balances and create new addresses.

In the coming weeks we will be adding better descriptions and ticker differentiation for bitcoin forks.

Generate bitcoin wallet seed from fingerprint?

I was wondering is there an app that generates a bitcoin seed from your fingerprint data. Would this be a good way to avoid problems from losing your password?
Edit for clarity... Im not talking about a fingerprint that can be lifted. I mean with a fingerprint reader such as on a mobile phone. I was under the impression these needed a "live" finger to actually read them.

Generate bitcoin wallet completely offline

I want to open a bitcoin account, but I am wary of all the online services to do so. I also don't trust my PC enough to install software there and be sure that it doesn't get stolen. What I want to do is to generate the bitcoin account(public key+private key) myself by using calculator and a piece of paper if the algorithm is not very involved. If the algorithm is too complicated I want to write a python script to do it for me. In any case I just want to know, what is the algorithm to generate bitcoin account?

safe offline key generating bitcoin wallet?

It really should not be that hard to have a device like the trezor that has no network capabilities that is a safe alternative to mastering electronic encryption. My goal is to find a device that can generate a valid key from your three inputs: your private key that you obtain from your paper wallet, the public key that you want to send an amount to and the amount you want to send. It then spits out the key you can publish to get integrated into the block chain. This would ensure you need physical access to the wallet to use it and with some moderate password protection (which one would be the best alternative here??) impenetrable.
Is there some solution already out there that I can not find?
EDIT: This is obviously a wallet for longer term storage, not for everyday payment for which I would still use a low-quantity wallet on my smartphone.
EDIT2: this Guide describes what I am seeking but I still want to be able to make transactions eithout the use of a USB device

What's Bitcoin Core behavior after running out of the 999 receiving and change addresses it generates when creating a wallet?

Does it starts reusing them from the beginning again? Or does it keeps generating addresses 1000, 1001, 1002, etc?
If the latter, what are the implications for when you restore from your hdseed? Do you need to take extra steps to make your wallet aware of beyond 999 addresses?
What's the Electrum behavior for this? How many addresses it generates by default?

Why does Bitcoin Core generates a new hdseed after encrypting the wallet?

Wouldn't it be enough to just encrypt the current hdseed together with its current keypool?
Why generating a new hdseed and a new extra keypool?

Generating HD wallet addresses from xpub key using PHP, up to date method? $100 BTC reward for help!

Hi, I've been trying to get this working for a short while now and I am at a loss of what else to do.
I initially found this guide: https://freedomnode.com/blog/58/generate-bitcoin-wallet-addresses-from-extended-public-key-with-php
But have been getting this error:
Fatal error: Uncaught InvalidArgumentException: Invalid fingerprint for BIP32 key, must be in range [0 - (2^31)-1] inclusive in [path_redacted]\vendor\bitwasp\bitcoin\src\Key\Deterministic\HierarchicalKey.php:82 
I believe this error is caused by a fairly recent change to the repository, I've tried using these examples:
https://gist.github.com/daftspunk/8cc1dd787e97bcf4fa563a83102597c1
https://www.reddit.com/Bitcoin/comments/4j468c/php_to_generate_hd_addresses_coding_issues/
Same issue, can anyone with more knowledge on this help to debug? Able to offer a $100 BTC reward! Thanks :)

How are unique links or strings like Bitcoin wallet address generated? At one point it seems that checking if that string is taken seems not efficient, is it just taking the chance and hoping such string will never be generated again ?

'''


  1. Added Metamask wallet to chrome, remitted an amount of ETH to its address, but the balance is still zero.
  2. After careful inquiry, there are two transactions at this address, one is the received ETH, and the other is an automatically generated transaction.
  3. Later, multiple ETH tests were sent to the wallet address, all of which are the same, and a transaction is automatically generated.

Is there anyone who encounter this phenomenon, what is the reason?
