Now it's this

{ fetchFromGitHub
, stdenv
, pkgs
, lib
}: pkgs.buildGoModule rec {
  pname = "neutrond";

  version = "2.0.0";

  src = (fetchFromGitHub {
    owner = "neutron-org";
    repo = "neutron";
    rev = "v${version}";
    sha256 = "sha256-NuoOlrciBeL2f/A7wlQBqYlYJhSYucXRhLgxdasfyhI=";
  });

  vendorHash = "sha256-uLInKbuL886cfXCyQvIDZJHUC8AK9fR39yNBHDO+Qzc=";
  # vendorSha256 = lib.fakeSha256;

  doCheck = false;
  
  meta = with lib; {
    description = "Neutron node";

    longDescription = ''
      Neutron node to interact with neutron blockchain
    '';

    homepage = "https://github.com/neutron-org/neutron";
    
    license = licenses.asl20; # Apache license

    maintainers = with maintainers; [
      pr0n00gler
      foxpy
    ];

    platforms = platforms.all;
  };
}

what if you add:

  ldflags = [ "-w -s" ];
