Technical Deep Dive: The Open Parts Network

    Under the hood of our BSV-powered architecture — from one-satoshi availability tokens to credentialed logistics and LARS/CARS overlays.

    1. One-Sat Availability Token Model

    Each stock item is represented by a single satoshi UTXO whose locking script encodes:

    • SKU or manufacturer part number (hashed for privacy)
    • Quantity, unit price, and currency
    • Location hash (lat/long or facility code)
    • Expiry timestamp so stale listings self-invalidate

    Scripts follow the Lookup Availability pattern (BRC-25) — minimal and SPV-friendly, allowing any wallet to spend the token to both reserve the stock and pay the supplier in a single output.

    2. Distributed Lookup API

    Suppliers run a lightweight index micro-service that advertises a zero-config “parts-lookup” capability. Buyers send one request:

    GET /lookup?mpn=42-13MM-BOLT&radius=250km

    The service responds with a list of UTXO references + signed metadata. It’s the same handshake pattern asLookupResolver, so code reuse is high.

    3. BRC-52 / BRC-53 Provenance Chain

    OEMs issue digital batch certificates as BRC-52 credentials. When suppliers mint their availability tokens they append a pointer to the relevant certificate. Down-stream actors (inspectors, carriers) append BRC-53 attestations to the same UTXO chain, creating an immutable QA timeline.

    Tamper-Proof Certificates

    QR-scan the box on arrival; wallets verify the OEM signature instantly — no HTTPS call required.

    Credentialed Hand-Offs

    Every transfer (forklift → truck → drone) is logged by spending and re-locking the same UTXO to the next actor.

    4. LARS / CARS Overlay for Rich Data

    High-res manuals, images, or test-bench sensor streams live off-chain inside globally replicated object stores. Each chunk hash is reserved inside a companion output, so auditors can reconstruct any reconstruction path from raw parts to installation.

    Sub-Cent Storage Fees

    Anchoring 1 GB of documentation costs less than $0.10 in miner fees.

    5. Instant Settlement & Partial Fills

    Buyers optionally split tokens to support partial quantity fills. Thanks to BSV’s low fees, micro-settlements (even for a single bolt) are economical and final within seconds.

    Smart Escrow Options

    Funds auto-release on delivery confirmation without a third-party escrow agent.

    6. Reference Repo & Sample Flows

    We maintain an open-BSV demo stack. We can help you adapt:

    • TypeScript SDK for token minting & lookup
    • React hooks for BRC-100 wallet interactions
    • sCrypt contract templates for conditional escrow
    • Docker compose for local multi-supplier network
