WebOur DL-based threshold signatures are the first two-round scheme with security proved based solely on the discrete logarithm assumption in the ROM. The most efficient protocol is FROST [KG20,BCK`22], which is slightly more efficient than our scheme since it generates plain Schnorr signatures; however, FROST relies on the stronger OMDL assumption.
