NOTE - please look at env.go for the most up to date environment variable configurations.

The PathToBlocklistTxtFile environment variable (PATH_TO_BLOCKLIST_TXT_FILE) should point to a .txt file, use absolute paths. The .txt file should contain valid Filecoin addresses, 1 per line like:

t0123
t15vmf65zmgphczybqlhc6dnfntve4c7sk7eflmly

Local dev:

Load environment variables (been using direnv) so: with a .envrc and then direnv allow

cd filecoin-ffi && make && cd ../
go run *.go
