Native libraries and PLONK parameters

Section titled “Native libraries and PLONK parameters”

The publish output includes the native FROST and PLONK libraries for the runtime you chose (-r), including arm64 builds for linux-arm64. Run the libraries that ship with the release: the FROST library is pinned to version 0.2.0-frost-real, and a node that loads any other version stays out of vBTC key ceremonies and signings.

On first start the node downloads vfx_plonk_v4.params (about 400 MB) into PlonkParams in its data directory and verifies its SHA-256. Set VFX_PLONK_PARAMS_PATH to the full path of an existing copy to skip the download. A copy that doesn’t match the pinned hash is ignored.
