    Bitcoin core still does not connect with most HWW directly. The last answer is amazing - it solved my problem. I'll do just that. Thanks Andreas!!

    It"s good, that Bitcoin core support BIP 39 and pip 32 hierarchal deterministic wallets?

    Very interesting FAQ, thank you. About hardware wallet, I would add the following question: How can we be sure that hardware wallet are not pre-seeded or there is no failure (like not well randomized seed generator) ?

    • @b.griffin317
      @b.griffin317 5 лет назад +1

      others are saying trezor is open-source, so somebody would've seen that by now?

    • @maartenarnou
      @maartenarnou Год назад +1

      @@b.griffin317 Correct. Open-source is a very important feature of any hardware wallet

  • @sys8188
    @sys8188 6 лет назад +2

    Just on the mnemonic phrase topic, say that Trezor is stolen, the race to sweep the wallet begins. as ordering a new Trezor may take some time. what do you suggest to open that 24 word phrase to re send the funds somewhere else? this is a very very important step.

    • @codymiller8505

      What is the risk to having it stolen? How is someone going to steal your crypto?

  • @hitwill

    Very informative . A.A. - What is the best way to store the BIP 39 phrase? Perhaps encode it in some way and keep it online, to protect from the sock drawer attack? Or bury it in the ground, or a bank safe?

    • @codymiller8505
      @codymiller8505 6 лет назад +1

      hitwill your 12,18,24 word seed should never, ever, EVER be put on an electronic device of any sort. Period. If it is on a device, it is compromised. It should be written on a piece of paper by you and only you. It should not be photographed. You should physically secure it. This is the best way to ensure that your seed is both secure and unknown to anyone.

  • @hhhgggds
    @hhhgggds 6 лет назад

    Andreas, security wise would you recommend trezor one or model t? They say firmware is different on model t implying like it is " better ". Is that just marketing to sell new more expensive option or it actually is?

  • @vhs431

    Andreas, at 16:55 you state that one can initialize a „watch-only“ bitcoin core node with an xpub key so that it watches the balance of your wallet. I‘ve tried importing my xpub key into my satoshi 0.16.1 node, but get error messages „...must be hex string“. How exactly are you supposed to do that? The answers on stackexchange say it’s impossible...

    What if a crypto wallet manufacturer is corrupt? They have your wallet's "seed words." Right? So, they can use your seed words to take your Bitcoin?

    16:54 - Bitcoin Core supports BIP-39? I think this is an error.

    what if trezor company is not there is 10 years how would that work?

    • @aantonop
      @aantonop  6 лет назад +2

      It would still be possible to use the hardware wallet with a different software wallet (ex. Electrum). As long as you have the mnemonic backup, you can import the private keys to any compatible wallet.

    • @Xgrosz
      @Xgrosz 6 лет назад

      aantonop thank you can you also confirm that there is no way SatoshiLabs have our private keys
      I would like my viewers to hear it from you directly

  • @dajosova

    Andreas, thanks once again. I've bought a BitFi "unhackable" wallet... but I'm not sure if it is safe or not since BitFi company did not release their algorithm to the public yet and I don't know what device hardware really does.
    Would you have any advice on this, please. Cheers!

    • @don.mccracken
      @don.mccracken 6 лет назад

      I would also like to hear Andreas’ view on the new Bitfi hardware wallet. To me, it look extremely promising, since the keys are generated on the fly by the device, after entering your passphrase, and only the signed transaction is transmitted over Wi-Fi, not the private key itself. And if I understand it correctly, it seems like we should be able to use any Bitfi wallet to send coins from the Bitfi dashboard website, since nothing is stored on the device itself. And if so, that’s a huge bonus.

    • @dajosova
      @dajosova 6 лет назад

      Yep, precisely... it's open source too but I would like an expert/tech opinion.
      It also supports many coins such as Monero which is great. I bought it, received it but hadn't use it yet. I will with some amount and wait further for more technical reviews since it's something really new but a nice concept (quad-core processor, touch screen, WiFi and a leather wallet).
      It cost 120$, paid with Bitcoin... unfortunately the customs of my country (Portugal) and also UPS ate a lot of money.
      Final cost: almost 190€ (222$).

  • @robertklaassen2628
    @robertklaassen2628 6 лет назад

    How is this concept ever going to be adopted cheaply, securely and to be easy to use worldwide? In the way this sounds, this will never reach all the poor people in the world in which this was initially intended and promoted along that lines in the beginning. And my first and foremost concern is having my personal information (ID) online in order to have a variety of transactional wallets.

    • @b.griffin317
      @b.griffin317 5 лет назад

      in what way is your ID online to have wallets? IP? coinbase or similar account?

  • @mencheswest8993
    @mencheswest8993 6 лет назад

    Please guys tell me how much time will take to find the keys for satoshi's wallet, for any "lost forever" wallet. if the key is just a number-letter line in the right order then find it by simple guessing is just a matter of time and energy, right?

    • @mencheswest8993
      @mencheswest8993 6 лет назад

      Freedom ForAll its not about mnemonic frase, the actual private key like ey37eyw8383gw8w8e7wy3g3ue88eu3h3heie8833 etc.
      Isn't it possible to find it with enough attempts? The question is how much time it takes with enough hardware. . Prove me if I am wrong

    • @codymiller8505
      @codymiller8505 6 лет назад +1

      MAX WEST youre right, but you would need BILLIONS of attempts per second for TRILLIONS of years in order to break the private keys. There are more combinations of words for your key than atoms in a billion galaxies. It is an unfathomably large number. Theres a reason that Ledgers slogan is "safety in numbers".
