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:
- 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() - 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
