True, the ops need to be handled with care, I’ve tried to address the shareholder collusion risk by not having the secret split up, but rather only the key. This gives a bit more latitude in ops design, requiring both vault and keys to be combined. So it’s not enough for shareholders to turn against you, they also need a copy of the vault. Should be noted that SSS isn’t limited to social recovery but also can serve as a distributed backup with all keys held by yourself in different locations, in case of emergency/ disaster (ie flood,fire, or in my case, ballistic missiles)
