Blockstream Jade looks interesting.
Camera/ true air gap, color screen, open sources $69.
I’m a huge fan and supporter of Coldcard, but think it is good to have a few trusted vendors.
What are your thoughts on using Blockstream’s ‘blind oracle’ instead of a secure element? Seems a little ‘ledger like’ but not as bad?
You can always build a #[2]
Looks like with Jade you can setup your own blind oracle server? Could be fun.
SeedSigner also doesn’t store the private key on the device, it uses a QR code that the seed signer camera recognizes.
Which is the safest for my 1000 Bitcoin is the question??
Someone should do a Bitcoin wallet write-up..
Forgive me, but what is a secure element? We have the less-expensive Ledger, and have been satisfied until the FUD of today on Nostr. Wired magazine did a great article on it a few months ago, but after reading the feed on Nostr today, doubts are creeping in.
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.
Would love a technical person to give an expert opinion on how secure this is. I’m not sure.
To the layman this ledger controversy and questioning any one hardware wallet massively increases the value of multisig with hardware wallets from multiple vendors.
I have a jade I have not yet setup, still in packaging. When I do so, it will not be network connected. This rules out a default setup using Blockstreams blind oracle and necessitates running one locally, which they've documented the basic steps for here.

It makes for a more complicated setup, but feasible. Still, not something I'd recommend to non technical.
Good point. If you don’t want it to ever touch the network, you’ll have to use your own blind oracle server.
I have a Jade and am not very impressed by it. All the connectivity features (QR, bluetooth) were very finicky and not reliable. Coldcard is way better IMO, the NFC just works and the interface is way smoother.
Jade says, “true air gap” but you have to connect to their server to sign..
You could to use your own off-net computer at home, but at that point ide rather have a secure chip…..
