Perry's Résumé - Blockchain Engineering

/Architected a complete blockchain-based monetary system; smart contracts, cryptographic identity, zero-knowledge privacy primitives, and economic mechanism design. Guided teams through cryptographic and distributed systems architecture./

• Designed the Alberta Buck protocol, a full Ethereum EVM smart contract system comprising:

  • BUCK (ERC-20): Identity-aware fungible token with continuous demurrage accounting, on-chain credit-limit enforcement against pledged assets, and Chaum-Pedersen NIZK re-encryption proofs gating every counterparty-pair transfer.
  • BUCK_CREDIT (ERC-721): Insured real-world-asset NFTs with deterministic depreciation curves and parametric insurance integration; the collateral backing the ERC-20 supply.
  • IdentityRegistry: On-chain PS-signature credential registry with ElGamal-encrypted identity points, verified via BN254 precompile NIZK at registration; the trust anchor every transfer is gated on.
  • Notes: Privacy-preserving bearer-instrument layer. Tornado-style incremental Poseidon Merkle commitment pool with Groth16 SNARK batch-mint and per-flavor spend circuits. Three flavors (A1 addressed cheque, A2 private cheque, B1 bearer cheque) collapse to two circuit shapes covering every deferred-approve use case: self-wormholes, signed cheques, printable paper notes indistinguishable from cash.
  • BUCK_K: PID-controlled algorithmic issuance stabilizer referencing a commodity-basket price oracle; automated monetary policy without central bank intervention.

• Composed and verified the full cryptographic stack with executable py_ecc sanity checks on BN254 (formal verification by qualified mathematicians and cryptographers remains to be done):

  • Pointcheval-Sanders signature rerandomization for unlinkable credentials.
  • Chaum-Pedersen re-encryption equality proofs for bilateral identity disclosure; proved completeness, special soundness, and honest-verifier zero-knowledge, lifting to NIZK via Fiat-Shamir in the random oracle model.
  • A-spend and B-spend SNARK soundness, confirming that only the named recipient can deposit an addressed note and that bearer-cheque deposit always identifies the depositor.
  • Domain-separated Poseidon PRF nullifiers with double-spend prevention across both note flavors.
  • Mutual-decryptability invariant preservation; every note spend yields bilateral identity disclosure between counterparties.

• Designed economic mechanisms for MEV-resistant DeFi integration:

  • Analyzed how PID-controlled issuance (with proportional and derivative terms) automatically counteracts whale manipulation of BUCK/stablecoin AMM pools; the system transfers the attacker's assets to legitimate credit holders.
  • Modeled the effect of front-running-resistant oracle design: multiple independent controller implementations (PID, Kalman-filtered PID, MPC) with median-value aggregation prevent any single oracle compromise from moving the issuance multiplier.
  • Designed parametric default insurance with risk-proportional premium investment in a mutual insurance pool; algorithmic premium setting eliminates underwriter discretion.

• Built Python simulation and modeling infrastructure:

  • Full economic simulations of mortgage vs. BUCK issuance across 25-year horizons.
  • Seigniorage extraction analysis: proved commercial banks earn 2× the profit of a private lender on identical loans, solely from the regulatory privilege of ex-nihilo deposit creation.
  • Commodity-basket stability analysis (BCPI + labour) demonstrating BUCK would have been more stable than CAD$ over the last 50 years.
  • Statistical PID controller tuning for the BUCK_K Value Stabilization Factor.

• Developed widely-used open-source cryptographic libraries:

  • python-slip39: Cross-platform Shamir secret sharing for BIP-39 seed backup and recovery.
  • ezpwd-reed-solomon: High-throughput C++/JS Reed-Solomon FEC, used by aerospace and defense systems globally.
  • cpppo: Industrial EtherNet/IP protocol implementation in Python.

Architected and tested prototypes of HoloFuel's novel partition-tolerant transaction engine in Rust.

• Implemented agent-centric accounting enabling linear O(n) scaling vs. O(n²) blockchain bottlenecks; each agent held its own signed transaction chain, with bilateral settlement during network partitions.
• Validated simultaneous atomic transactions across partitioned networks; demonstrated that mutual-credit systems can settle without global consensus.
• Developed statistical models and PID control systems for economic stabilization across distributed agents.
• Contributed to R&D for Holochain's distributed application framework.

Built fault-tolerant distributed telemetry consensus without synchronized state machines.

• Architected real-time SDR system processing 25 Msps I/Q signals on commodity hardware; consensus on meter readings across lossy RF channels without global coordination.
• Optimized AVX/NEON SIMD vector processing for multi-channel demodulation at the network edge.
• Implemented fault-tolerant distributed consensus for partial data collected from multiple samples across unreliable channels.

Deployed partition-resilient SCADA maintaining safety-critical consensus during network splits.

• Architected Reed-Solomon erasure-coded multi-route protocol enabling real-time SCADA operation through crippling communications failures; a BFT-style availability guarantee implemented a decade before blockchain made the terminology common.
• Implemented multi-path routing maintaining cryptographic integrity across hostile network environments.
• Developed solid-state RTU firmware for 24/7 pipeline control with <1 defect per 10,000 LOC.
• Secured communications for $100B+ critical energy infrastructure.

Pioneered state-machine consensus for distributed industrial control systems.

• Re-engineered RTAP's core SCADA alarm system with DFA state machines for geographically distributed safety-critical workflows; deterministic state transitions without central coordination, deployed continent-wide and still operational after 30+ years.
