Module Tezos_base . Block_header
type shell_header = {
level : Int32.t;(*

Height of the block, from the genesis block.

*)
proto_level : int;(*

Number of protocol changes since genesis modulo 256.

*)
predecessor : Tezos_crypto.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 of validation passes (also number of lists of operations).

*)
operations_hash : Tezos_crypto.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.Context_hash.t;(*

Hash of the state of the context after application of this block.

*)
