A secure element(chip) is what actually stores your private bitcoin key, so it can sign transactions. If someone steals your device, someone can hack it and steal your private key, if not in a secure element.

Jade and SeedSigner do it differently, they don’t have a dedicated secure element, but use a form of multi party encryption (QR code or blind oracle)..

#BlockstreamJade oracle is open source.

It does not and cannot see anything.

You could even run your own.

Rumour of Umbrel integration for it coming soon too 👀

I like that you can run your own blind oracle..

Thinking using Blockstream as a blind oracle is totally different, safer than the Ledger fiasco..

Very disturbing. Or, very comforting depending on how you look at it. So a border agent could confiscate your wallet and hack it to get your keys/coin. Question is: ditch the Ledger, or take our chances.

@NVK​ is the secure element pro white Coldcard offers the latest in duel vendor secure elements..
