bls

Precompiled bls library for go

This library use the precompiled bls and mcl. Thank herumi for the great work.

And this library also bundle with GMP for the dependency.

Note

Because of the precompiled libs are managed by git-lfs, so before go get github.com/moonfruit/bls or simply clone the repository, you must install git-lfs first.
