Welcome back to Blockstream Talk #30 - Today, we're in conversation with Ken Sedgwick from VLS, the Validating Lightning Signer project. An open-source initiative focused on enhancing lightning node security through fully validated remote signing. The project aims to safeguard node funds by separating private keys via remote signers. Ken elaborates on the challenges of running a Lightning node compared to a Bitcoin hot wallet and discusses potential applications of VLS software in signing devices. While Lightning Network Security might not be top of mind for most users, its importance grows with the network's expansion. As adoption increases, including more retailers, users, and larger nodes, Ken adeptly communicates these intricate concepts. Enjoy the discussion and share with your Bitcoin network.
