HARDWARE WALLETS FOR LIGHTNING NETWORK
With Bitcoin you can "be your own bank", with Lightning it's time to "be your own Visa". The main challenge in both cases is to secure your private keys. In Bitcoin we already have hardware wallets for this purpose, for lightning they still need to be developed. Lightning requires much more functionality compared to a simple prepare-sign-broadcast approach used in Bitcoin. During the talk I will cover what functionality we need from hardware wallets for Lightning Network, what attacks are possible and how to handle them in a compromised host model. We will discuss challenges and trade-offs between security, privacy and convenience when designing a hardware wallet for lightning node. We will also talk about different use-cases like a routing node operating with minimal user interaction.
