The Block Entity

Block entity represents the summary of a block from the blockchain.

type BlockSummary struct {
	Version 	      string `json:"version" msgpack:"_v"`
	CreationDate 	      common.Timestamp `json:"creation_date"`

Field	Description
version	Version of the block. Latest is "1.0".
creation_date	Time when the block is created.
hash	Hash of the block, which represents a SHA256 hash represented in hex string for all the fields of the block concatenated together and separated with :.
miner_id	The ID of the miner generated the block.
round	Round when the block was generated.
round_random_seed	Seed number used to generate random numbers.
state_changes_count	Count of changes applied on the MPT state.
merkle_tree_root	Current root of the MPT computed from the transactions contained inside the block.
state_hash	Hex hash of the root of the MPT.
receipt_merkle_tree_root	The root of an MPT computed from the transactions of the block.
num_txns	Number of the transactions in the block.
magic_block	Magic Block entity used while generating the block.
