Perry's Résumé - Distributed Systems & P2P Protocols

Architected and tested prototypes of HoloFuel's partition-tolerant transaction engine in Rust, on Holochain's agent-centric distributed application framework.

• Designed the accounting model explicitly as an alternative to blockchain-style global ordering: each agent holds its own signed transaction chain, counterparties settle bilaterally, and the network never blocks on a global consensus round.
• Implemented agent-centric accounting enabling linear O(n) scaling vs. O(n²) blockchain bottlenecks, with settlement continuing during network partitions.
• Validated simultaneous atomic transactions across partitioned networks; demonstrated that mutual-credit systems can reach cryptographic finality without global consensus.
• Developed statistical models and PID control systems for economic stabilization across distributed agents (holofuel-model, and the much more advanced alberta-buck).
• Contributed to R&D for Holochain's DHT-based distributed application framework.

/Protocol, authorization and communications R&D for industrial, energy and fintech clients; remote systems that run unattended for years. Guide teams through cryptographic and distributed systems architecture./

• Authorization without central accounts:

  • localwebauthn: self-hosted WebAuthn/FIDO2 passkey relying party; credentials and authentication material never leave the operator's infrastructure.
  • crypto-licensing: Ed25519-signed, offline-verifiable licenses with DNS-based public key distribution (DKIM model); possession of a signed token grants a scoped right to a specific resource, with no license server in the critical path.

• Protocol and coding libraries in wide use:

  • cpppo: Python EtherNet/IP and CIP protocol implementation, deployed globally as the integration layer between analytics systems and PLCs.
  • ezpwd-reed-solomon: high-throughput C++/JS/Python Reed-Solomon and BCH codecs, used by aerospace and defence developers for data on lossy channels.
  • python-slip39: cross-platform Shamir secret sharing for seed backup and recovery.
• Delivered rugged satellite-connected monitoring, communications and video systems across Alberta oilfields: intermittent, high-latency links, field-serviceable, diagnosable from 400 km away.
• Designed and delivered a production generative-AI service with three interchangeable inference backends and copy-on-write session cloning, chosen deliberately for vendor reversibility and data sovereignty.
• Mitigated a critical security flaw in a globally deployed enterprise collaboration suite.

• Designed the Alberta Buck protocol, a complete wealth-backed monetary system, as a worked example of carrying a protocol from mechanism design to a checkable specification:

  • Identity-aware transfers gated on Chaum-Pedersen re-encryption proofs; unlinkable Pointcheval-Sanders credentials; privacy-preserving bearer notes over Poseidon Merkle commitment pools with Groth16 spend circuits.
  • Composed and sanity-checked the full cryptographic stack with executable py_ecc tests on BN254; proved completeness, special soundness and honest-verifier zero-knowledge of the bilateral disclosure proofs (independent formal review remains to be done).
  • PID-controlled issuance with median-aggregated independent controllers for oracle manipulation resistance; multi-year economic simulations in Python.
  • Architecture · Formal Proofs · Identity System · Implementation
• Actively share research code and papers; author technical articles on Holochain, consensus, signal recovery and industrial communications.

Replaced custom radio telemetry with commodity hardware and SDR; reached agreement on meter readings across lossy RF channels without global coordination.

• Built a fault-tolerant SDR system processing 25 Msps I/Q across 120 channels on commodity CPUs.
• Designed the decoding and reconciliation pipeline so that independently received, partially corrupted readings converge on a consistent result at the edge, with no central arbiter.
• Optimized multi-channel demodulation with AVX/NEON; integrated with flight-approved hardware, power and communications equipment.

Designed and deployed a cryptographically secured, Reed-Solomon erasure-coded, multi-route communications protocol for real-time pipeline SCADA; still in operation today.

• Architected the transport to keep control traffic flowing through crippling communications failures: erasure coding across independent routes rather than retry on a single path.
• Implemented multi-path routing maintaining cryptographic integrity across hostile networks.
• Developed solid-state RTUs for 24/7 control; <1 defect per 10K LOC in mission-critical firmware protecting $100B+ infrastructure.
• Deployed hundreds of ruggedized units across critical infrastructure sites.

Re-architected the core alarm system of the RTAP SCADA platform around DFA state machines.

• Enabled deterministic state transitions across geographically distributed SCADA nodes without a central coordination authority.
• Enabled end-users to configure complex, distributed safety-critical workflows.
• Remains in operation in pipeline SCADA systems continent-wide, 30+ years on.
