Block

The Block entity provides a normalized representation of the Casper Network block. It doesn't contain the executed deploy hashes as the network block object. However, they could be queried separately using the Deploy API.

Properties

The Block entity has the following properties:

Property	Type	Description
block_height	uint64	Block height. Primary block identifier
block_hash	string(64)	Block hash represented as a hexadecimal string. Secondary block identifier
parent_block_hash	string(64)	Parent block hash represented as a hexadecimal string
state_root_hash	string(64)	Identifier of the network's state after executing the block's deploys represented as a hexadecimal string
era_id	uint32	Era ID in which the block was created
proposer_public_key	string(68)	Public key of the validator who proposed the block represented as a hexadecimal string
native_transfers_number	uint16	Number of native transfer deploys included in the block
contract_calls_number	uint16	Number of contract calls included in the block
is_switch_block	bool	true if the block is the last one in the era
timestamp	datetime	The timestamp from when the block was proposed
