Blockchain technology has matured to the point where banks, fintechs, and global financial institutions now view it as foundational infrastructure for modern capital markets, drawn by advantages like tokenized assets, 24/7 settlement, and seamless cross-border transactions.

But this momentum hits a wall when it confronts regulatory reality.

Across the U.S. and globally, regulators evaluate blockchain networks through a consistent lens: Who is in control?

If any actor within a network can materially influence transaction outcomes, whether through ordering, prioritization, or censorship, the network risks being treated as a regulated intermediary. Even the possibility of such control creates regulatory uncertainty and raises concerns about market manipulation, regardless of intent.

So, how do you build a system that's rigorously compliant?

Secure Block Building (SBB) provides the technical foundation institutional chains need to meet regulatory standards from day one. It eliminates intermediary-like control at the protocol level, removing the risk that draws regulatory scrutiny and reducing the compliance burden for institutions operating in regulated markets.

But regulatory readiness is only the starting point. SBB moves beyond simple compliance checklists and ensures operational resilience and long-term economic efficiency:

1. Regulatory-readiness: SBB establishes the network as non-intermediary from through neutral transaction ordering. No single actor or coordinated group can unilaterally order, censor, or prioritize transactions.

2. Operational resilience: SBB preserves system integrity under adverse conditions, delivering continuous, fault-tolerant operations that withstand attacks and failures.

3. Scalable revenue: SBB enables efficient market operations that support long-term revenue models. Through transparent price discovery (via built-in arbitrage markets), it creates the economic conditions necessary for institutional-scale markets to thrive.

SBB proves that transaction ordering is neutral by design. It uses cryptographic guarantees to ensure the ordering entity is blind to transaction contents before they are submitted to the chain.

In this demo, SBB applies FCFS (First-Come, First-Served) ordering:

• The ordering entity cannot view transaction contents at the time of ordering, regardless of gas fees.

• This removes the ability, or even the opportunity, for any actor to exert independent control over transaction ordering.

Eliminating intermediary control, reinforcing decentralization, and maintaining transparent behavior are foundational to reducing regulatory risk. SBB delivers these properties at the protocol level, enabling institutions to build onchain infrastructure that meets the demands of modern global finance.
