Coinbase's advanced cryptography library
Caution
This fork is not maintained actively, it is only used as a way for the Obol team to update critical dependencies on Charon. It will be deprecated soon
Caution
The FROST DKG implementation in this repository might be vulnerable to a DDoS attack, which could potentially disrupt the keys being generated. Charon is immune to that thanks to its defensive programming approach.
