ZKsync Founder Refutes Canton’s "Systemic Risk" Claims on ZKPs

Alex Gluchowski, co-founder of ZKsync, has issued a detailed response to assertions made by the founder of the Canton Network, who previously characterized Zero-Knowledge Proofs (ZKPs) as a systemic risk to institutional finance. Gluchowski argues that the complexity of ZKPs is not an inherent flaw but a manageable technical challenge, asserting that the ZK-based architecture offers superior security through redundancy and isolation compared to the centralized operator models found in permissioned systems.

Redundancy and Blast Radius Control

Gluchowski’s rebuttal focuses on the principles of high-integrity systems, drawing parallels with aviation and nuclear power. He contends that while all complex systems possess potential vulnerabilities, security is achieved by implementing multiple independent defenses and limiting the "blast radius" of any single failure.

• Independent Defenses: ZK-based architectures utilize decentralized verification layers, reducing reliance on any single entity.
• Isolation: By partitioning the network, ZKPs can prevent a local vulnerability from impacting the entire financial ecosystem.
• Transparency: Unlike proprietary models, ZKP systems allow for public auditing of the underlying cryptographic logic.

In contrast, Gluchowski points out that the Canton architecture relies on a single operator trust mechanism. This structure, he argues, creates a single point of failure, which poses a more significant risk to institutional stability than the mathematical complexity of ZKPs.

Open-Source Testing vs. Proprietary Languages

A central point of the critique involves the reliability of the execution environment. Gluchowski emphasized that the Ethereum Virtual Machine (EVM), which serves as the foundation for many ZK-rollups, has undergone years of intensive, open-source stress testing. This collective scrutiny by thousands of global developers provides a level of security assurance that closed proprietary languages used by private blockchains like Canton cannot match.

The ZKsync co-founder noted that the mathematical guarantees of ZK-rollups provide "incorruptible" infrastructure. This is particularly relevant as the industry moves toward the Atlas upgrade, which aims to deliver transaction speeds exceeding 15,000 TPS and one-second finality, further closing the gap between public blockchain performance and traditional financial requirements.

Any complex critical system will have vulnerabilities; the core of its security lies in redundancy and limiting the blast radius, rather than avoiding complexity altogether.

Conclusion

The debate highlights a growing philosophical and technical divide between supporters of permissioned institutional networks and those advocating for ZK-powered public infrastructure. While Canton focuses on legal enforceability and permissioned privacy, Gluchowski maintains that cryptographic proofs and open-source ecosystems offer a more resilient foundation for the future of global finance. As institutional interest in tokenization grows, the security and scalability of ZK-based solutions like ZKsync remain at the forefront of the industry's evolution.
