Dynamic-FROST: Schnorr threshold signatures with a flexible committee

Threshold signatures enable any subgroup of predefined cardinality tt out of a committee of nn participants to generate a valid, aggregated signature. Although several (t,n)\left(t,n)-threshold signature schemes exist, most of them assume that the threshold tt and the set of participants do not chan...
