Governance of BSC
There are many system parameters to control the behavior of the BSC:
All these parameters of BSC system contracts should be flexible: slashing threshold, cross-chain transfer fees, relayer reward amount and so on.
params of Staking/Slash/Oracle/IBC modules on BC
All these parameters will be determined by BSC Validator Set together through a proposal-vote process based on their staking. Such process will be carried on BC, and the new parameter values will be picked up by corresponding system contracts via cross-chain communication when needed.
