### Validator
|
||||
|
||||
Validators are identified according to the `ValOwnerAddr`,
|
||||
an SDK account address for the owner of the validator.
|
||||
Validators are identified according to the `OperatorAddr`, an SDK validator
|
||||
address for the operator of the validator.
|
||||
|
||||
Validators also have a `ValTendermintAddr`, the address
|
||||
of the public key of the validator.
|
||||
Validators also have a `ConsPubKey`, the public key of the validator.
|
||||
|
||||
Validators are indexed in the store using the following maps:
|
||||
|
||||
- Validators: `0x02 | ValOwnerAddr -> amino(validator)`
|
||||
- ValidatorsByPubKey: `0x03 | ValTendermintAddr -> ValOwnerAddr`
|
||||
- ValidatorsByPower: `0x05 | power | blockHeight | blockTx -> ValOwnerAddr`
|
||||
- Validators: `0x02 | OperatorAddr -> amino(validator)`
|
||||
- ValidatorsByPubKey: `0x03 | ConsPubKey -> OperatorAddr`
|
||||
- ValidatorsByPower: `0x05 | power | blockHeight | blockTx -> OperatorAddr`
|
||||
|
||||
`Validators` is the primary index - it ensures that each owner can have only one
|
||||
associated validator, where the public key of that validator can change in the
|
||||
future. Delegators can refer to the immutable owner of the validator, without
|
||||
concern for the changing public key.
