Expand description

Parameters describing epoch configuration of a Cardano chain

A Partner Chain must be aware of slot and epoch configuration of its Cardano main chain to be able to correctly observe its state.

Additionally, the Partner Chains Toolkit:

  • can only observe Cardano state produced during Cardano Eras no older than Shelley
  • expects the Cardano main chain’s epoch and slot duration to remain constant throughout the lifetime of a particular Partner Chain

Because of those constraints, the configuration includes a reference point in time from which it is safe for a Partner Chain to observe its main chain’s history. This reference point should be the beginning of some Cardano epoch. For most Partner Chains a good default value is the beginning of the Shelley era on their main chain. If the main chain’s slot or epoch duration was changed after it entered Shelley era, the reference point should be one after this happened, eg. the beginning of the first epoch in which all slots are of the new duration.

Fields§

§epoch_duration_millis: Duration

Duration of a single epoch on the Cardano main chain

This value must remain constant after first_epoch_timestamp_millis.

§slot_duration_millis: Duration

Slot duration of the Cardano main chain

This value must remain constant after first_epoch_timestamp_millis.

§first_epoch_timestamp_millis: Timestamp

Reference point in time from which the Cardano main chain’s state is safe for a Partner Chain to be observed.

This timestamp should be the starting timestamp of the Cardano epoch and slot indicated by first_epoch_number and first_slot_number.

§first_epoch_number: u32

Number of the Cardano Epoch starting at first_epoch_timestamp_millis

§first_slot_number: u64

Number of the Cardano slot starting at first_epoch_timestamp_millis
