Libbbf: Bound Book Format, A high-performance container for comics and manga
Summary
BBF: Bound Book Format is a high-performance binary container optimized for digital comics and manga, using DirectStorage-friendly mmap, 4KB alignment, and per-asset XXH3-based integrity checks. It supports deduplication, mixed-codec assets (AVIF/PNG), and a hierarchical, metadata-rich structure with a CLI (bbfmux) for ingestion, verification, and extraction. The format claims significant speed and space advantages over traditional formats like CBZ/CBR and emphasizes verifiable archival integrity.
