brew install fails for blst / libblst on macOS m series

[kushal2060]

While installing libblst it says:

Warning: No available formula with the name "libblst". Did you mean libbsc, libbsd, libplist, libxls, libpst, librist or librest?
==> Searching for similarly named formulae and casks...
==> Formulae
libbsc libbsd libplist libxls libpst librist librest

To install libbsc, run:
brew install libbsc

and for blst:
Warning: No available formula with the name "blst". Did you mean blast?
==> Searching for similarly named formulae and casks...
==> Formulae
blast

So i used nix as nix-shell -p pkg-config libsodium blst secp256k1 zlib
