Insecure Lightning Node? VLS Fixes This
summary
Claims a hardened signer that enforces Lightning rules before signing so a compromised node cannot steal funds, implemented as an open source VLS remote signer that already supports core-lightning and LDK via Docker and has finished tag team signing; a Validity prototype runs the signer inside an OP-TEE secure enclave on ARM using QEMU or inexpensive hardware such as a Radxa Rock 4 $60 and can also target tiny devices (ESP32/STM32) or HSMs for higher assurance.
