Despite rapid technical advancements in the blockchain space, integrating these new technologies into established financial systems presents complex challenges. Howard Wu, Founder of Aleo and CEO of Provable, an Aleo Labs company renowned for developing compliant and confidential payment products, recently offered insights into the evolving non-technical hurdles institutions face in adopting privacy-preserving blockchain solutions.

Wu, whose notable contributions to zero-knowledge proofs (ZKPs) and elliptic-curve cryptography (including Zexe and DIZK) have been adopted by protocols such as Ethereum, Zcash, and Aleo itself, identified regulatory uncertainty as the primary non-technical barrier for the longest time.

“The biggest non-technical hurdle for the longest time was regulatory uncertainty,” Wu stated.

However, as clarity begins to emerge on the regulatory front, particularly within the U.S., Wu believes a new and formidable challenge has taken its place: implementation. “Now that we’re getting more clarity there, at least in the US, the new hurdle is implementation,” Wu explained.

This shift brings forth critical questions for institutions: How will blockchain and ZKPs effectively integrate into their intricate existing systems? Where can these cutting-edge technologies provide the most tangible value? And perhaps most crucially, who will assume leadership in developing the necessary technological connections to bridge the old with the new?

When pressed on the role of education in accelerating the adoption of ZK proof-based solutions among traditional financial institutions, Wu emphasized a crucial distinction. While Aleo itself aims to simplify the underlying mechanics—it abstracts away much of the complexity of zero-knowledge proofs, making it simpler than ever for developers to build private decentralized applications (dApps)—the focus for traditional finance (TradFi) executives is different.

“Truthfully, TradFi executives don’t need to understand the intricacies of zk-SNARKs,” Wu argued. “Instead, their knowledge gap is fundamentally about understanding the practical applications and strategic benefits. They need to understand how ZKPs reduce operational risk, lower compliance costs, and create competitive advantages.” For Wu, the core questions executives are asking are “what can we use it for, why should we invest in integrating?”

When explaining Aleo’s capabilities, Wu focuses on concrete outcomes that resonate directly with institutional pain points. He highlights scenarios such as: “You can prove regulatory compliance without exposing customer data” and “You can minimize the amount of data your company holds, reducing the risk of a data breach and reducing the amount of laws you need to comply with.” This approach, he insists, aims to demonstrate tangible value rather than technical detail.

Beyond mere technical integration or the creation of new software solutions, the adoption of privacy-preserving blockchain technologies demands comprehensive internal restructuring. According to Wu, this includes extensive retraining of compliance teams, updating established internal controls, and meticulously creating new governance structures tailored for a decentralized future.

Meanwhile, Wu told Bitcoin.com News that he foresees ZKPs introducing proper privacy and guardrails to build compliant crypto-based payment systems.

“The issue today is that if financial institutions used blockchains as they are today, they would reveal sensitive information, including customer addresses, customer balances, business revenues, and business intelligence that could benefit competitors—to name a few,” the CEO said.

This switch is poised to accelerate the adoption of permissionless blockchains across a range of high-value use cases—including financial settlements, tokenized securities, and seamless cross-border payments. Crucially, these innovations can unfold without compromising regulatory compliance, thanks to the emergence of sophisticated tools that integrate transparency, auditability, and decentralized trust mechanisms into previously siloed systems. The result is a more inclusive, interoperable financial ecosystem capable of scaling global commerce with integrity and efficiency.

Turning to the regulatory landscape, which is constantly evolving, Wu argues that regulators do not inherently desire less privacy. Rather, the current system is designed in a way that often exposes the personal information of innocent individuals in the pursuit of identifying malicious actors. He notes that existing regulatory oversight, while rigorous through methods like sampling, cross-referencing, and on-site examinations, is both expensive and invasive. The Provable CEO again touts ZKPs as the panacea to the problem.

“ZKPs could streamline these existing verification mechanisms by enabling more regular monitoring instead of periodic intensive audits—all while preserving the regulatory judgment and policy-setting that human oversight requires,” the CEO stated.

Looking ahead, Wu expresses optimism for the development of “ZKP-native” regulatory frameworks within the next few years. These frameworks would be specifically designed around principles of data minimization and privacy for all users, fundamentally changing how compliance is achieved. He implies that privacy-preserving technologies, when properly understood and integrated, have the potential to accelerate regulatory clarity by providing a more effective and less burdensome means of ensuring compliance, rather than complicating it.
