Module `Tezos_base.Block_header`Source

Sourcetype shell_header = {

level : Int32.t;
(*
Height of the block, from the genesis block.
*)
proto_level : int;
(*
Number (uint8) of protocol changes since genesis modulo 256.
*)
predecessor : Tezos_crypto.Hashed.Block_hash.t;
(*
Hash of the preceding block.
*)
timestamp : Time.Protocol.t;
(*
Timestamp at which the block is claimed to have been created.
*)
validation_passes : int;
(*
Number (uint8) of validation passes (also number of lists of operations).
*)
operations_hash : Tezos_crypto.Hashed.Operation_list_list_hash.t;
(*
Hash of the list of lists (actually root hashes of merkle trees) of operations included in the block. There is one list of operations per validation pass.
*)
fitness : Fitness.t;
(*
A sequence of sequences of unsigned bytes, ordered by length and then lexicographically. It represents the claimed fitness of the chain ending in this block.
*)
context : Tezos_crypto.Hashed.Context_hash.t;
(*
Hash of the state of the context either before or after application of this block depending on the protocol environment's expected_context_hash value.
*)
