pub fn set_proofs_parameter_cache_dir_env(data_dir: &Path)
Expand description
Forest uses a set of external crates for verifying the proofs generated by
the miners. These external crates require a specific set of parameter files
to be located at in a specific folder. By default, it is
/var/tmp/filecoin-proof-parameters
but it can be overridden by the
FIL_PROOFS_PARAMETER_CACHE
environment variable. Forest will automatically
download the parameter files from Cloudflare/IPFS and verify their validity. For
consistency, Forest will prefer to download the files it’s local data
directory. To this end, the FIL_PROOFS_PARAMETER_CACHE
environment
variable is updated before the parameters are downloaded.
