Hardware Transaction Verification: Eliminating Software Vulnerabilities with FPGA-Based 2PC

Hardware Transaction Verification with Distributed Locking, Two Phase Commit, and Automatic Recovery

Applied mathematician Alex Boyarskiy has developed a unique hardware verification project designed to protect against hacker attacks. The system replaces vulnerable software logic with an FPGA/ASIC implementation to ensure atomic execution of transactions.

Why This Matters

Traditional software-defined security layers often introduce excessive vulnerabilities through complex codebases and network dependencies. By shifting critical verification logic—such as balance checks and uniqueness validation—to isolated hardware without direct network interfaces, the system removes the server as a trusted component and eliminates common attack vectors like software-level memory corruption or OS exploits.

Key Insights

• Collision Elimination: A 64-bit password P = [32 bit hardware counter] ⊕ [16 bit internal time] ⊕ [16 bit TRNG] mathematically eliminates replay attacks (Boyarskiy, 2026).
• Atomic Execution via 2PC: The system implements a Two Phase Commit (Prepare → Commit) using a dedicated serial bus to ensure transactions are either fully executed or rolled back.
• Write Ahead Logging (WAL): The architecture prioritizes MRAM for the L1 journal before updating FRAM balances to prevent data loss during power failures.

Practical Applications

• High-Security Financial Gateways: Using isolated FPGA boards to verify balances; avoids the pitfall of relying on untrusted external servers which can lead to unauthorized fund debits.
• Critical Infrastructure Control: Implementing physical ‘Update Enable’ jumpers for blacklist modifications; avoids the anti-pattern of remote administrative access which often leads to unauthorized system overrides.
