  2. Pedersen Verifiable Secret Sharing
  3. Pedersen Distributed Verifiable Secret Sharing
  4. Feldman Verifiable Secret Sharing
  5. Feldman Distributed Verifiable Secret Sharing
  6. Secure Distributed Key Generation for Discrete-Log Based Cryptosystems
  7. Distributed Key Generation from FROST
  8. Distributed discrete log (DLOG) check
