Taking Self-Custody of Your Bitcoin with Blockstream Jade

TLDRBlockstream Jade is a hardware wallet that offers self-custody of your Bitcoin. It provides a unique set of features, including air gaped transactions, QR code support, and compatibility with Bitcoin and assets on the Liquid sidechain. The device uses a different security model and does not rely on a traditional secure element. Instead, it encrypts the private key and uses a blind Oracle to decrypt it. The firmware can be upgraded using the Blockstream Green app or the upgrade web portal.
