package tezos-protocol-014-PtKathma
This modules handles all the validation/application/finalisation of any operation related to the DAL.
val validate_data_availability :
Alpha_context.t ->
Alpha_context.Dal.Endorsement.t ->
unit Tezos_protocol_environment_014_PtKathma.Error_monad.tzresultvalidate_data_availability ctxt endorsement ensures the endorsement is valid and cannot prevent an operation containing endorsement to be refused on top of ctxt. If an Error _ is returned, the endorsement is not valid.
val apply_data_availability :
Alpha_context.t ->
Alpha_context.Dal.Endorsement.t ->
endorser:Tezos_protocol_environment_014_PtKathma.Signature.Public_key_hash.t ->
Alpha_context.t Tezos_protocol_environment_014_PtKathma.Error_monad.tzresult
Tezos_protocol_environment_014_PtKathma.Lwt.tapply_data_availability ctxt endorsement ~endorser applies endorsement into the ctxt assuming endorser issued those endorsements.

Alpha_context.Dal.Slot.t ->
unit Tezos_protocol_environment_014_PtKathma.Error_monad.tzresultvalidate_publish_slot_header ctxt slot ensures that slot is valid and cannot prevent an operation containing slot to be refused on top of ctxt. If an Error _ is returned, the slot is not valid.

Alpha_context.t Tezos_protocol_environment_014_PtKathma.Error_monad.tzresultapply_publish_slot_header ctxt slot applies the publication of slot header slot on top of ctxt. Fails if the slot contains already a slot header.

Tezos_protocol_environment_014_PtKathma.Error_monad.tzresult
Tezos_protocol_environment_014_PtKathma.Lwt.tdal_finalisation ctxt should be executed at block finalisation time. A set of slots available at level ctxt.current_level - lag is returned encapsulated into the endorsement data-structure.
lag is a parametric constant specific to the data-availability layer.
