He believes that self-custody is crucial because it allows individuals to truly own their Bitcoin and have control over their funds. He recommends using a hardware wallet for self-custody, especially for those with a significant amount of Bitcoin. Aaron explains that a hardware wallet securely stores private keys and allows users to securely sign transactions. He also highlights the importance of secure elements in hardware wallets to prevent physical attacks and reduce the attack surface for private keys. The Keystone hardware wallet is designed to provide a secure and user-friendly self-custody solution for cryptocurrencies. It uses a touch screen display and QR code data transmission to enhance user experience and reduce vulnerabilities. The Keystone 3 is built from scratch, with a focus on security and simplicity. The trade-off made was to remove the Android system and use a general-purpose microcontroller to run the firmware. The Lightning Network and the intersection of AI and blockchain are areas of interest for the guest. While Bitcoin is the primary focus, the guest acknowledges the value and innovation in other cryptocurrencies.
