Known Issues
2026: Simplicity versus advanced air-gap features
Jade Core removes the camera, battery, SD/USB-drive features, and JadeLink workflows found on Jade Plus, making it easier and cheaper but less suitable for users who want full air-gapped operation.
2026: Virtual secure element debate
Jade Core uses the same blind-oracle virtual secure element design as the broader Jade line, preserving open-source hardware while remaining controversial for users who prefer traditional secure-element chips.
