Actor Selection

The CometBFT consensus algorithm selects the acting validator. The algorithm selects Block creators for each epoch/block.

The thereby elected validator is the master of ceremony for this very execution of the PoP and performs the following actions

1. selects a challenger and a challengee

2. verifies their availability via m2m (mqtt)

3. notarizes the selection via an InitPoP message containing

   • the validator-address,

   • challenger address

   • challengee address

   • block height

4. sends a PopInit command containing the block height of the PoP to the challenger and the challengee with the expectation that both will perform the PoP.
