BlockHeader(Int32, Int64, String, ImmutableArray<Byte>, ImmutableArray<Byte>, Int64, BigInteger, ImmutableArray<Byte>, ImmutableArray<Byte>, ImmutableArray<Byte>, ImmutableArray<Byte>, ImmutableArray<Byte>)

Creates a BlockHeader instance.

Declaration

public BlockHeader(int protocolVersion, long index, string timestamp, ImmutableArray<byte> nonce, ImmutableArray<byte> miner, long difficulty, BigInteger totalDifficulty, ImmutableArray<byte> previousHash, ImmutableArray<byte> txHash, ImmutableArray<byte> hash, ImmutableArray<byte> preEvaluationHash, ImmutableArray<byte> stateRootHash)

Parameters

Type	Name	Description
Int32	protocolVersion	The protocol version. Goes to the ProtocolVersion.
Int64	index	The height of the block. Goes to the Index.
String	timestamp	The time this block is created. Goes to the Timestamp.
ImmutableArray<Byte>	nonce	The nonce which satisfy the given `difficulty` with any other field values. Goes to the Nonce.
ImmutableArray<Byte>	miner	An optional address refers to who mines this block. Goes to the Miner.
Int64	difficulty	The mining difficulty that `nonce` has to satisfy. Goes to the Difficulty.
BigInteger	totalDifficulty	The total mining difficulty until this block. See also Difficulty.
ImmutableArray<Byte>	previousHash	The previous block's Hash. If it's a genesis block (i.e., `index` is 0) this should be `null`. Goes to the PreviousHash.
ImmutableArray<Byte>	txHash	The result of hashing the transactions the block has. Goes to the TxHash.
ImmutableArray<Byte>	hash	The hash of the Block<T>. Goes to the Hash.
ImmutableArray<Byte>	preEvaluationHash	The hash derived from the block except of `stateRootHash` (i.e., without action evaluation). Used for Libplanet.Blocks.BlockHeader.Validate(System.DateTimeOffset) checking `nonce`.
ImmutableArray<Byte>	stateRootHash	The Hash of the states on the block.
