Browse Source 
* babe: add babe module trait

* babe: track current slot and epoch start slot

* babe: implement ShouldEndSession based on epochs

* babe: rename weight type to avoid ambiguities

* babe: expose epoch start slot in Epoch digest

* babe: use epoch start for validating epoch transitions

* babe: make the epoch duration a parameter type

* babe: remove unused fields from config

* node: update runtime to use babe instead of aura

* node: use babe instead of aura

* core: generate sr25519 keys from seed and add to keystore

* core: remove AuthorityKeyring

* node: remove unused primitive types related to babe crypto

* uniform babe primitives crate import name

* node: bump spec_version

* node: fix import

* babe: don't use constants in storage fields array sizes

* babe: account for first epoch slot way in the past

* babe: signal next epoch change (not current)

* babe: calculate next epoch randomness with next epoch index

* babe: track next epoch in node

* babe: cache current epoch and authorities separately
