The distribution module is responsible for fee distribution, and staking token provision distribution. This simple distribution mechanism describes a functional way to passively distribute rewards between validators and delegators. Note that this mechanism does not distribute funds as precisely as active reward distribution mechanisms and can be upgraded in the future. For more information, visit https://docs.cosmos.network/main/modules/distribution/
