BlockHeader class

BlockHeader defines information about a block and is used in the bitcoin block (MsgBlock) and headers (MsgHeaders) messages.

Constructors

BlockHeader({required int version, required Hash prevBlock, required Hash merkleRoot, required DateTime timestamp, required int bits, required int nonce})

Creates a new BlockHeader with the specified fields.

const

BlockHeader.deserialize(Uint8List data)

Deserializes a block header from bytes using Bitcoin protocol encoding.

factory

BlockHeader.genesis({int version = 1, Hash? prevBlock, Hash? merkleRoot, DateTime? timestamp, int bits = 0x1d00ffff, int nonce = 0})

Creates a BlockHeader from a genesis block configuration.

factory

Properties

bits → int

Difficulty target for the block.

final

hashCode → int

Hash code implementation.

no setter, override

merkleRoot → Hash

Merkle tree reference to hash of all transactions for the block.

final

nonce → int

Nonce used to generate the block.

final

prevBlock → Hash

Hash of the previous block header in the block chain.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

timestamp → DateTime

Time the block was created. This is encoded as a uint32 on the wire and therefore is limited to 2106.

final

version → int

Version of the block. This is not the same as the protocol version.

final

Methods

blockHash() → Hash

Computes the block identifier hash for this block header.

copyWith({int? version, Hash? prevBlock, Hash? merkleRoot, DateTime? timestamp, int? bits, int? nonce}) → BlockHeader

Creates a copy of this block header with optional field overrides.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

serialize() → Uint8List

Serializes the block header to bytes using Bitcoin protocol encoding.

toString() → String

Returns a string representation of the block header.

override

Operators

operator ==(Object other) → bool

Equality operator.
