[−][src]Struct bls_like::TinyBLS
Infrequently used BLS variant with tiny 48 byte signatures and 96 byte public keys,
We recommend gainst this variant by default because verifiers
always perform O(signers) additions on the PublicKeyGroup,
or worse 128 bit scalar multiplications with delinearization.
Yet, there are specific use cases where this variant performs
better. We swapy two group roles relative to zcash here.
