type sources_config = private {

min_agreement : float;
(*
A float between 0 (exclusive) and 1 (inclusive), representing the minimum ratio of endpoints that must agree on data for said data to be accepted. 1 means "require all enpoints to agree" (the default).
*)
uris : Uri.t list;
(*
The list of endpoint URIs used for Light mode consensus. This list must contain at least 2 endpoints (one for data retrieval, one for check).
*)

}

See mk_sources_config smart constructor to build values.

val example_sources : string

An example content of the --sources file

val destruct_sources_config : 
  Tezos_base.TzPervasives.Data_encoding.json ->
  (sources_config, string) Stdlib.result

Ad-hoc type safe JSON parsing function until json-data-encoding library provides a result-returning alternative.

val sources_config_to_uris : sources_config -> Uri.t list

sources_config_to_uris sources returns the Uris contained * in sources.

val sources_config_to_sources : 
  (Uri.t -> Tezos_rpc.Context.simple) ->
  sources_config ->
  sources

sources_config_to_sources f config transforms the value config (which was obtained by parsing the CLI) into a value used by core algorithms of the light mode.

val hash_of_block : 
  Tezos_shell_services.Block_services.block ->
  Tezos_base.TzPervasives.Block_hash.t option

None if the given block is symbolic, otherwise its concrete hash.
