Cool tidbit: other than SeedSigner,
Blockstream (npub1jg5…6n8n) Jade is the only fully open-source Bitcoin hardware wallet that is impervious to physical key extraction.
You must collect three separate secrets to decrypt your keys: one is in the encrypted blob on the device, the second is the user-generated pin you set, and the third is only accessible via the blind oracle (that you can also run yourself).
Only with all three secrets, can you then get and decrypt the private key. So, by not having a secure element directly on the device, but rather this unique security model of three decentralized secrets, physical key extraction is not possible.
Bonus tidbit: the Jade is 50%-75% cheaper than any of the other Bitcoin hardware wallet on the market, meaning you can buy two or three of them (or even build a DIY ver for $15) for the cost of the others, allowing you to create your own multisig.
Jade definitely doesn’t get the attention it deserves!
Heading to Pacific Bitcoin by Swan (npub1tft…xar5)?
Make sure your first stop is the Blockstream booth so you can get your hands on the new Jade stock!
