Module Extensions

Transition frontier extensions defines the set of extensions which are * attached to an instance of a transition frontier. A transition frontier * extension is an incrementally computed view on the transition frontier's * contents. Extensions synchronously recieve diffs applied to the transition * frontier. Every extension is associated with a broadcast pipe, which allows * outside consumers of extensions to recieve updates a extension's view. * Calling notify from this module will update all extensions with the new * transition frontier diffs, waiting for all consumers of each extensions' * broadcast pipes to finish handling any view updates that may occur.

module Best_tip_diff : sig ... end
module Identity : sig ... end
module Root_history : sig ... end

The root history extension provides a historical view into previous roots the * transition frontier has maintained. The root history will store at most the * 2*k historical roots.

A ledger table maps ledger hashes to ledgers
