PQCCustody: Lattice-Based MPC Sharding, Air-Gapped Cold Enclaves & Multi-Signature Governance

PQCCustody provides institutional-grade digital asset custody, threshold lattice signature schemes (t-ML-DSA), air-gapped hardware security modules (HSM), and SEC/FCA compliant governance frameworks to protect financial institutions, sovereign wealth funds, and exchanges from quantum financial theft.

PQCCustody Institutional Vault Architecture & Governance Topology

Multi-signatory quorum, air-gapped optical data diodes, and cold-storage HSM enclave

Central System: Institutional Vault Core - Threshold Lattice HSM Enclave

Cryptographic Nodes

  • Air-Gapped Cold HSM
  • Optical Data Diode
  • t-of-n Quorum Engine
  • Regulatory Policy Enforcer
  • Disaster Recovery Bunker

Architectural Layers & Protocols

  • Air-Gapped Physical Security Plane (Class-4 High-Security Underground Vaults): Housing cold-storage HSMs in electromagnetic Faraday cages isolated from the public internet.
  • Threshold Lattice Cryptography (Threshold ML-DSA-87 (t-of-n) Signing Protocol): Requiring multiple C-level executives and compliance officers to sign without assembling the master key.
  • Unidirectional Data Transfer (Hardware Optical Data Diodes & QR Air-Gaps): Transferring unsigned transactions into the air-gapped vault via light pulses, preventing incoming cyberattacks.
  • Governance & Regulatory Compliance (SOC 2 Type II / SEC Rule 17a-4 / MiCA Standard): Enforcing dual-authorization, withdrawal velocity limits, and automated tamper-evident audit trails.

Key Metrics: t-of-n (Threshold Governance Quorum) | FIPS 140-3 L4 (Physical Hardware Standard) | $0 Breach (Historical Asset Loss) | 100% Air-Gapped (Zero Internet Connectivity)
