The team behind Validating Lightning Signer (VLS) will be hosting an AMA (Ask Me Anything) session on September 29th at 1500 UTC to answer questions about Lightning and how VLS works. VLS is a dedicated signer that enforces Lightning rules and user policies before releasing a signature, keeping Lightning keys and signing logic isolated to enhance node security. The session aims to provide insights into the technology and its potential to strengthen node security by enforcing Lightning rules and policies.
