FROSTR () takes advantage of Schnorr signatures—which are much more flexible than the old standard—to allow multiple people to share control of a single Nostr account. It uses a method called FROST to let a group (like 2-out-of-3 people) sign off on posts or actions directly through Nostr.
This is a brilliant approach because it allows for easy key updates and better security. It’s very similar to the enterprise-grade tools we are building at PrivKey.io.
