[ANN] Krogothmanhattan x Polymerbit: Customer DIY key generation with Trezor

[anonymousminer]

Much love to both of you guys, but this idea is terrible.  Sure, you guys and a few of the collectors can have this new idea on a few notes etc... Woohoo... but what average collector is going to spend $70 plus shipping etc on a trezor, to basically light it on fire by exposing the keys... just to buy a $25 note??  I just think that some people are having a hard time accepting that newly made loaded collectibles are going by the wayside....

 For peace of mind for my BTC…hell yeah…$70 is worth it and it ain’t a one time use for one note…can be used over and over again for any item using this method.

    So its not a waste of waste of money at all…the Trezor can also be used to store your personal Bitcoin stash as well if need be. That’s exactly what I used for the key generation for this note.  Used my personal BTC stash Trezor…simply reset…generated the keys and voila….done deal. All I had to do is reset back and input my original seed for my original BTC…and was back in business.

   And I completely agree with your comment of newly made loaded collectibles are going by the wayside…Trust has been lost especially since Dogg fucked everyone. Also when BTC hit its all time high…guess what a lot of collectors did? Peeled and swept due to anxiety of the BTC getting swept. Especially high value items from past coin makers as well...If done this way...guess who doesn't have to worry about losing their BTC?

   That’s why this way you simply cannot have that happen to you and newly loaded collectables can be sold in that light as well. This is an option a maker can incorporate in their collectables as well as having them issue private keys for people that want them as well.

     But again to each his own as I have said before on earlier threads.

No - I am suggesting they might be doing it - who knows right? It is my fear with any hw wallet - or that they use a preset number of pk’s etc - i would rather trust a collectible maker than a hw maker.

    I see your point....yeah who knows....maybe the roll of the dice is the way to go and generate your own seed that way.

    Nothing is guaranteed in life except Death..and taxes. 

    The main reason I like Trezor is, its open source and has been tested and can be tested for what it is and what it is not.

    I love my paper wallets as well, but the convenience a hardware wallet gives me is much easier than a paper wallet.

     Do you know of anyway you can convert your seed into the actual Public and Private key addresses? I mean without going thru a hardware wallet.

     There has to be something or code out there that can do it especially on Github.

I wonder if they store em like trezor did - without telling anyone. Ledger has been splitting keys to shards and now want to charge a subscription to “recover” your keys.  This is my fear of all hw wallets - that they are secretly storing/saving keys and that is why I dont truly trust any of them. Look at what just happened with Atomic wallet - supposed ti be non-custodial yet was actually custodial so keys were leaked.

  I have heard of ledgers key news...but about Trezor...this is a first...where exactly did you hear that? So Trezor is storing keys without telling anyone? If I am not mistaken Atomic is a hot wallet no?

yes non custodial but apparently they were still sending back everyones private keys.

    I love my paper wallets as well, but the convenience a hardware wallet gives me is much easier than a paper wallet.

a paper wallet can be loaded into a hot wallet and used just as easily as a trezor and use bip 38/39 and/or signing device to keep the key safe.

as for the second part - yes, I do it all the time I use core on an offline airgapped drive. but I guess you could call core a "HW" wallet as well.

Finally got a moment to sit down and check this out. Some interesting concepts. Will have to spend some more time digging in to understand it better as I learn a bit slower than most ya’ll, as I’ve of course made clear many a times. I cheers the effort though just trying to think of innovation ways to make things better. Regardless of the outcome, worth the shot!

I’ll happily take that note off your hands

   Ha!  That note you are referring to is loaded with $200 worth of Bitcoin at the time it was loaded...and I know and generated the passphrase.

    You are more than welcome to try and sweep the BTC if you can figure out what the passphrase/password is though....  

    You can see the seed mnemonic phrase is exposed for anyone to try.

    If you scan the public address QR code it is loaded with 0.00683764BTC

 So.....thanks to Crypto Great Dane we finally made a short video about this. Hope that clarifies things for people as to how its done.  Cheers!

Customer DIY key generation with Trezor


During brunch in NYC, Krog and I were discussing issues faced by the collectible community.  The fact that a buyer has to inherently trust the keymaker to remain honest is a flaw. Polymerbit attempted to test how the market reacts to an alternative by releasing those DIY triangle notes in A4 format. Our findings were clear; only one buyer actually reported adding keys on the note. The fact that most people do not have an air gapped printer, meant that few were willing to go ahead with DIY keys. This stopped the DIY project dead in its tracks, forcing us to scrap the rest of the series. Korg suggested to try something new that may be useful to various coin makers. All coin makers are welcome to test this as well. In theory, this should allow Trezor holders to easily request custom keys for works issued by Polymerbit and others.



A unique test print was made using this process, with the note being shipped to Korg. These notes would not be resold, but would be useful as gifts or for a personal collection.

WARNING: Run a malware and antivirus program prior to starting.

Reset a Trezor hardware wallet.
      Write down the 12- or 24-word seed clearly on a piece of paper in the right order
       Create a long passphrase, at least 16 characters long using letters, numbers and symbols. The longer the better.


       Copy the public address given for the passphrase hidden wallet. Copy the QR code as well by using a screenshot if need be.

      To verify correct transcription, you can confirm the backup via the Trezor “CHECK BACKUP” option or reset the Trezor, and input the seed and then the passphrase. If the correct seed and passphrase are input, then the same public address you have copied will be shown again. If not then you made a mistake and need to try again to confirm that what you wrote down is correct. There can be no errors in this procedure. Once they match, then send the public key to Polymerbit.


                          Sending the SEED and the PUBLIC KEYS to POLYMERBIT
 
             A different device should be used to send the seed to Polymerbit. This is so in the event the computer where the Trezor passphrase is being created is infected or has a keylogger, the only item the hacker will get is the passphrase, which will be useless without the seed.

For additional security, the seed could also be mailed physically.


ADDITIONAL INFO:

      So, as a precaution the seed should be uploaded to Polymerbit’s website via a different device. The passphrase and the seed should never be seen on the same computer at all to ensure there is no vulnerability.


   In the event the seed is compromised, it will be useless without the passphrase and the same if the passphrase is compromised, it is useless without the seed.

The passphrase should be made of alphanumeric/symbols and be at least 16 characters long. Customer should be made aware to never share it and to place in secure spot. As the only way to be able to redeem the notes is with that passphrase and without it, then the Bitcoin will be lost forever.

How about using a Satodime device for that key generation process ?
Private key will be sealed in a cold storage. And there is no security risk as the chip itself will generate the pair of keys (based on the user's co-provided entropy).

     I have bought and used Satodimes I like them. But how would you incorporate this into a physical Bitcoin? You would need to remove the chip from the card and place on the coin or note. I presume that is what you mean?

Hmm.. Good point, very interesting stuff ... Look forward to the reply here.
