Module Tezos_base.Block_header

type shell_header = {
level : Stdlib.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.
