BLS signatures have the same aggregation feature as Schnorr signatures but
even better because the aggregation can be done non-interactively, at the
expense of being a bit slower. We just released a first draft (but fully
functional) library for doing BLS signatures based on a construction based
on musig. Feedback, discussion, and usage is very welcome.

Awesome! Haven’t had the chance to run it myself yet, so curious what benchmarks you are getting?

Best,
