Next steps: * ~add [lagrange interpolation optimization](https://github.com/heliaxdev/group-threshold-crypto/issues/7) and benchmark for high thresholds (i.e. 8k)~ * ~implement https://github.com/heliaxdev/group-threshold-crypto/issues/8 and benchmark~

relevant issue for ferveo's TPKE part https://github.com/heliaxdev/arkworks-threshold-decryption/issues/16

Starting a conversation, here are some initial thoughts: ### Proposed methodology/flow (no strict order): 1. Define attack model * attacker profile(s) * environmental factors 2. Choose relevant side-channels (SC) 3....
