Validating Lightning Signer Separates Keys From Nodes By Marty Bent The Lightning Network has been at the top of mind for everyone as a Layer 2 solution for Bitcoin to achieve scaling for mainstream adoption. Up until this moment, it has been criticized as having a central point of failure, since the nodes have a need for uptime and the keys are normally stored in the physical device, making it a hot wallet. Finally this might be about to change. Sphinx team shared their new Lightning innovation by constructing a node leveraging Core Lightning and the Validating Lightning Signer architecture, which separates the keys from the Lightning node using a dedicated signing device. With this new feature, users would be able to run their nodes in the cloud, without having the risk of losing access to their bitcoin, even if the hosting server goes off. |
