§topic_weight: f64The weight of the topic.
time_in_mesh_weight: f64P1: time in the mesh
This is the time the peer has been grafted in the mesh.
The value of the parameter is the time/time_in_mesh_quantum, capped by
time_in_mesh_cap The weight of the parameter must be positive (or zero to disable).
time_in_mesh_quantum: Duration§time_in_mesh_cap: f64§first_message_deliveries_weight: f64P2: first message deliveries
This is the number of message deliveries in the topic.
The value of the parameter is a counter, decaying with first_message_deliveries_decay,
and capped by first_message_deliveries_cap.
The weight of the parameter MUST be positive (or zero to disable).
first_message_deliveries_decay: f64§first_message_deliveries_cap: f64§mesh_message_deliveries_weight: f64P3: mesh message deliveries
This is the number of message deliveries in the mesh, within the
mesh_message_deliveries_window of message validation; deliveries during validation also
count and are retroactively applied when validation succeeds.
This window accounts for the minimum time before a hostile mesh peer trying to game the
score could replay back a valid message we just sent them.
It effectively tracks first and near-first deliveries, ie a message seen from a mesh peer
before we have forwarded it to them.
The parameter has an associated counter, decaying with mesh_message_deliveries_decay.
If the counter exceeds the threshold, its value is 0.
If the counter is below the mesh_message_deliveries_threshold, the value is the square
of the deficit, ie (message_deliveries_threshold - counter)^2
The penalty is only activated after mesh_message_deliveries_activation time in the mesh.
The weight of the parameter MUST be negative (or zero to disable).
mesh_message_deliveries_decay: f64§mesh_message_deliveries_cap: f64§mesh_message_deliveries_threshold: f64§mesh_message_deliveries_window: Duration§mesh_message_deliveries_activation: Duration§mesh_failure_penalty_weight: f64P3b: sticky mesh propagation failures This is a sticky penalty that applies when a peer gets pruned from the mesh with an active mesh message delivery penalty. The weight of the parameter MUST be negative (or zero to disable)
mesh_failure_penalty_decay: f64§invalid_message_deliveries_weight: f64P4: invalid messages
This is the number of invalid messages in the topic.
The value of the parameter is the square of the counter, decaying with
invalid_message_deliveries_decay.
The weight of the parameter MUST be negative (or zero to disable).
