# State
The internal state of the `x/upgrade` module is relatively minimal and simple. The
state contains the currently active upgrade `Plan` (if one exists) by key
`0x0` and if a `Plan` is marked as "done" by key `0x1`. Additionally, the state
contains the consensus versions of all app modules in the application. The versions
are stored as big endian `uint64`, and can be accessed with prefix `0x2` appended
by the corresponding module name of type `string`.
- Plan: `0x0 -> Plan`
- Done: `0x1 | byte(plan name) -> BigEndian(Block Height)`
- ConsensusVersion: `0x2 | byte(module name) -> BigEndian(Module Consensus Version)`
The `x/upgrade` module contains no genesis state.
