New report outlines a modern alternative to “Exchange-in-a-Box” platforms and legacy market technology

NEW YORK, Jan. 15, 2026 /PRNewswire-PRWeb/ — Fundamental Interactions, a provider of high-performance electronic trading systems for regulated markets, today announced the release of a new white paper titled “Matching Engine Technology: Architecture, Determinism, and Comparison to Global Exchange Platforms.” The paper explains how deterministic system design enables modern exchanges and Alternative Trading Systems (ATSs) to achieve predictable execution, regulatory auditability, and long-term strategic independence.

As trading venues expand to support equities, private securities, and digital assets, many operators face difficult trade-offs between performance, compliance, and control. The white paper addresses these challenges by presenting a deterministic matching engine architecture modeled on the same design principles used by leading global exchanges, while remaining independent of exchange-operated outsourcing models.

“Market operators are under increasing pressure to launch quickly, but many turnkey solutions introduce hidden long-term risks around control, auditability, and strategic independence,” said Kun Luo, Chief Technology Officer of Fundamental Interactions. “This white paper demonstrates that venues can achieve exchange-grade performance without compromising deterministic behavior or regulatory confidence. A deterministic architecture provides a durable foundation for modern regulated markets.”

The white paper highlights several key themes:

• Deterministic Execution and Audit Replay
• Strict global event sequencing ensures identical outcomes from identical inputs, enabling exact replay for regulatory audits and investigations.
• Unified Multi-Asset Trading
• A single execution framework supports traditional securities, private markets, and digital or tokenized assets, reducing fragmentation and operational complexity.
• Strategic Independence
• Fundamental Interactions operates solely as a technology provider, allowing venues to retain full ownership of their execution logic, market data, and intellectual property.

The paper also examines the risks of exchange-operated “Exchange-in-a-Box” solutions and discusses how ATS operators can balance the build-versus-buy decision while preserving long-term enterprise value.
