Struct sc_authority_discovery::Worker

pub struct Worker<Client, Network, Block, DhtEventStream> { /* fields omitted */ }

An authority discovery Worker can publish the local node’s addresses as well as discover those of other nodes via a Kademlia DHT.

When constructed with Role::PublishAndDiscover a Worker will

1. Retrieve its external addresses (including peer id).

2. Get the list of keys owned by the local node participating in the current authority set.

3. Sign the addresses with the keys.

4. Put addresses and signature as a record with the authority id as a key on a Kademlia DHT.

When constructed with either Role::PublishAndDiscover or Role::Discover a Worker will

1. Retrieve the current and next set of authorities.

2. Start DHT queries for the ids of the authorities.

3. Validate the signatures of the retrieved key value pairs.

4. Add the retrieved external addresses as priority nodes to the network peerset.

5. Allow querying of the collected addresses via the crate::Service.
