HistoryLabs

Open-source strategies, zero-trust architectures, and turnkey blueprints for multi-generational digital preservation.

Digital records are inherently fragile. Unlike physical paper or clay tablets, digital data faces continuous threats from silent data corruption (bit rot), vendor lock-in, obsolete file formats, and storage media decay.

HistoryLabs provides vendor-neutral, open-source technical standards to ensure digital assets remain verifiable, intact, and readable across decades.

Core Pillars of Digital Preservation

1. Fixity & Integrity

Data that cannot be verified is data in decay. We mandate end-to-end cryptographic checksums (BLAKE3, SHA-256) combined with copy-on-write (CoW) filesystems running automated scrub routines to catch and repair bit rot before parity loss occurs.

2. Format Longevity

Avoid proprietary or unmaintained wrappers. All preserved assets are normalized into open, well-documented, uncompressed or losslessly compressed formats (FFV1 for video, FLAC for audio, PDF/A for documents, and PNG/TIFF for images).

3. Extended Redundancy

Single backups are single points of failure. We implement the extended 3-2-1-1-0 strategy:

• 3 copies of critical data
• 2 distinct media types (HDD + Optical/Tape)
• 1 offsite copy
• 1 air-gapped or immutable repository
• 0 unverified restores (automated fixity audits)
