Blockstream on Nostr: Physical secure elements are closed-source under NDA. Once reverse-engineered ...

Physical secure elements are closed-source under NDA. Once reverse-engineered offline, every unit is compromised.

Jade's virtual SE (Blind Oracle) encrypts your seed so the locked device holds only ciphertext. The AES-256 key is co-created with a truly blind, rate-limited oracle that wipes after 3 wrong PINs. The attack becomes interactive and remote.

Fully open-source. No proprietary silicon. No NDAs. Anyone can audit the code or run their own oracle.

We don't FUD secure elements, we simply explain why we chose the Blind Oracle path for greater transparency and verifiability.
