VLS separates your Lightning private keys and security rule validation from your Lightning node, into a discrete signing device. This improves LN security for users by reducing the attack surface.
This enhances security compared to existing blind signing nodes by validating that requests from the node are following the Lightning security model. You can sleep soundly, knowing a compromised LN node does not mean loss of funds.
As the Lightning network implementations of Taproot, Musig2 and FROST mature in the coming months, VLS will be a necessity in creating seamless multi-sig Lightning network channels.
