Immutable domain objects — the fundamental data model of the private-blockchain library.

Three classes form the immutable core:

  • Block — an immutable unit containing a list of transactions and a cryptographic link to the previous block (FR-CORE-01).
  • BlockHeader — a lightweight record holding the block's version, nonce, Merkle root, and timestamp for header-only validation (FR-CORE-05).
  • Transaction — the abstract base class that consumers must extend to define their own transaction types (FR-CORE-02).

All classes in this package are thread-safe and immutable after construction.
