Expand description

Runtime features.

Runtime features provide a mechanism for features to be simultaneously activated across the network. Since validators may choose when to upgrade, features must remain dormant until a sufficient majority of the network is running a version that would support a given feature.

Feature activation is accomplished by:

  1. Activation is requested by the feature authority, who issues a transaction to create the feature account. The newly created feature account will have the value of Feature::default()
  2. When the next epoch is entered the runtime will check for new activation requests and active them. When this occurs, the activation slot is recorded in the feature account
