Bastian Köcher f6f58f95e1 inspect-key: Adds support for expect-public (#10430 )

* Introduce `SecretUri`

* `inspect-key`: Adds support for `expect-public`

`expect-public` can be used to check that a given secret uri corresponds to the given public key.
This is mainly useful when the secret uri is protected by a password and a new derived account
should be generated. With `--expect-public` the user can pass the public key/account-id of the
"base" secret uri aka the one without any derivation to ensure the correct password was inserted.

* Fixes

* 🤦

* Apply suggestions from code review

I'm online Module

If the local node is a validator (i.e. contains an authority key), this module gossips a heartbeat transaction with each new session. The heartbeat functions as a simple mechanism to signal that the node is online in the current era.

Received heartbeats are tracked for one era and reset with each new era. The module exposes two public functions to query if a heartbeat has been received in the current era or session.

The heartbeat is a signed transaction, which was signed using the session key and includes the recent best block number of the local validators chain as well as the NetworkState. It is submitted as an Unsigned Transaction via off-chain workers.

Interface

Public Functions

is_online - True if the validator sent a heartbeat in the current session.

Usage

use pallet_im_online::{self as im_online};

#[frame_support::pallet]
pub mod pallet {
    use super::*;
    use frame_support::pallet_prelude::*;
    use frame_system::pallet_prelude::*;

    #[pallet::pallet]
    pub struct Pallet<T>(_);

    #[pallet::config]
    pub trait Config: frame_system::Config + im_online::Config {}

    #[pallet::call]
    impl<T: Config> Pallet<T> {
        #[pallet::weight(0)]
        pub fn is_online(origin: OriginFor<T>, authority_index: u32) -> DispatchResult {
            let _sender = ensure_signed(origin)?;
            let _is_online = <im_online::Pallet<T>>::is_online(authority_index);
            Ok(())
        }
    }
}

Dependencies

This module depends on the Session module.
