 - `max_validator_slots`: Maximum consensus validators, default `128`
 - `min_validator_stake`: Minimum stake of a validator that allows the validator to enter the `consensus` or `below_capacity` [sets](#validator-sets), in number of native tokens. Because the [inflation system](../inflation-system.md#proof-of-stake-rewards) targets a bonding ratio of 2/3, the minimum should be somewhere around `total_supply * 2/3 / max_validator_slots`, but it can and should be much lower to lower the entry cost, as long as it's enough to prevent validation account creation spam that could slow down PoS system update on epoch change
 - `pipeline_len`: Pipeline length in number of epochs, default `2` (see <https://github.com/cosmos/cosmos-sdk/blob/019444ae4328beaca32f2f8416ee5edbac2ef30b/docs/architecture/adr-039-epoched-staking.md#pipelining-the-epochs>)
