# 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`. 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`. The state maintains a
|
|
`Protocol Version` which can be accessed by key `0x3`.
|
|
|
|
- Plan: `0x0 -> Plan`
|
|
- Done: `0x1 | byte(plan name) -> BigEndian(Block Height)`
|
|
- ConsensusVersion: `0x2 | byte(module name) -> BigEndian(Module Consensus Version)`
|
|
- ProtocolVersion: `0x3 -> BigEndian(Protocol Version)`
|
|
|
|
The `x/upgrade` module contains no genesis state.
