Committee formation
How each epoch's MPC committee is drawn from the subnet.
Routing is computed by a committee of n Bittensor subnet validators. At the start of each epoch the committee is chosen by stake-weighted sampling from the validator set, using the same stake that Yuma consensus uses to weight scores.
Parameters
Set the reconstruction threshold t to a supermajority (t > n/2). A colluding group now needs more than half the committee, and that group's stake is what an attack puts at risk.
Committees rotate every epoch. No fixed group of nodes builds up a view of one trader's history over time.
Liveness
If fewer than t members take part within the time limit, the intent times out and funds go back to the trader. There is never a fallback to unshielded execution. The protocol gives up liveness to keep safety.
