Initializer

init(_:)

Parses a block header from its 80-byte serialized form.

init(_ data: Data) throws

Parameters

data: Exactly 80 bytes of serialized header data.

Discussion

The input must be exactly 80 bytes in the standard header layout. Parsing checks only that the data is structurally a header — no proof-of-work check, no linkage check. Those happen in processBlockHeader(_:state:).

Throws

KernelError.blockHeaderCreationFailed when the input is not exactly 80 bytes or otherwise fails to parse.
