BLS is a digital signature scheme with compression properties. With a given set of signatures (signature_1, ..., signature_n) anyone can produce a compressed signature signature_compressed. The same is true for a set of secret keys or public keys, while keeping the connection between sets (i.e., a compressed public key is associated to its compressed secret key). Furthermore, the BLS signature scheme is deterministic, non-malleable, and efficient. Its simplicity and cryptographic properties allows it to be useful in a variety of use- cases, specifically when minimal storage space or bandwidth are required.
