This discusses how the Hub resolves delta conflicts. Each delta has a unique conflict ID and state. The winner of conflicting messages are determined by timestamp and then by hash ID. https://www.youtube.com/watch?v=QtAS4PkrGOc&list=PL0eq1PLf6eUdm35v_840EGLXkVJDhxhcF&index=7

A delta is things that a user can do on a social network. A delta graph is used to store and share messages between hubs on a social network. https://www.youtube.com/watch?v=JcO9UA2R6JY&list=PL0eq1PLf6eUdm35v_840EGLXkVJDhxhcF&index=6&t=2s

Farcaster enables account recovery by allowing a recovery address to transfer an ID to a new address with a graceful period of allowing the transfer to be cancelled by the original address when necessary. https://www.youtube.com/watch?v=DnAG4mXlOFI&list=PL0eq1PLf6eUdm35v_840EGLXkVJDhxhcF&index=4
