I would like a hardware wallet for zcash.
If someone knows of a device with ability to create zero knowledge proof, please let me know.
The 4 GB RAM requirement will probably mean no existing devices are able to?!?
If you are developing one please read my "wish-device"
Thin, square Touchscreen device with around 6.5x6.5cm and camera on the back.
USB-C to charge only - meaning processor etc is not connected to the usb to avoid possible hacks.
no nfc, bluetooth, wifi, firmware updates, etc possible
communication with the internet is through barcodes (qr or possibly colour) screening and scanning with the camera
possibility to exchange messaging keys (pgp,etc) in person through barcodes
popular os apps to send encrypted message via barcode to wallet device, there decrypt, read and write answer, encrypt it and send back to app via barcorde
those apps should also be able to send ZCash adresses, then wallet shows transaction to verify, then creates zero knowledge proof and sends it via barcode to app. from there to zcash network
sorry might sound bit confusing. in any case let me know if you hear of any ZCash hardware wallets
