 these tokens) to a validator, forming a validator pool. The weight that validators give to blocks is derived from the
 total stake of the pool (i.e., from the locked tokens of the staker and the delegated tokens of all its delegators) and
 the total combined stake among pools. If the validator of a pool performs its task well, the pool is rewarded with Mana.
