Module notify 

A task that runs an external command whenever the best chain tip changes.

This is Zebra’s port of zcashd’s -blocknotify. Whenever the node’s best chain tip changes, and the node is close to the network tip (Zebra’s analogue of “not in initial block download”), the configured command is run via the system shell with every %s replaced by the new tip’s block hash. The command is run detached and never blocks block validation.
