ZKsync Founder Slams Canton's 'Single Point of Trust' Risk

ZKsync Founder: Canton's Model Creates a 'Single Point of Trust'

ZKsync founder Alex Gluchowski directly refuted criticism from the Canton Network's founding team, who questioned the fitness of Zero-Knowledge (ZK) proofs for institutional finance due to their perceived complexity. Gluchowski countered that Canton's architecture, which depends on trusted operators for data isolation, constitutes a "single point of trust." He argued this model presents a more significant systemic danger than the potential for software bugs in ZK systems, which are mathematically verifiable and secured by the underlying public blockchain.

The core of the disagreement lies in two opposing philosophies for institutional security. ZKsync champions a model based on cryptographic guarantees, where transaction validity can be proven without revealing sensitive data. In contrast, Canton and its backers, like Digital Asset co-founder Shaul Kfir, insist that cryptographic security cannot replace legal enforceability, viewing traditional legal frameworks as the ultimate arbiter in disputes.

Three Competing Visions Emerge for Institutional Privacy

The debate between ZKsync and Canton reflects a broader industry-wide race to define the privacy standards for tokenized assets. Three primary technologies are competing for dominance: ZK proofs, permissioned networks, and Fully Homomorphic Encryption (FHE). While ZKsync's Prividium network offers a privacy layer for public blockchains, Canton provides a network of permissioned ledgers designed for data isolation among participants.

A third approach is gaining traction through cryptography startup Zama, which raised $73 million in a 2024 Series A funding round. Zama is commercializing FHE to allow computations on encrypted data, which founder Rand Hindi positions as a complementary technology. FHE aims to solve the "shared state problem" by enabling collaborative workflows on sensitive data without decryption, bridging a gap that affects both ZK and permissioned models. This technological divergence underscores the high stakes involved in building the foundational infrastructure for regulated digital assets.

ZKsync Partners With BitGo for Institutional Tokenized Deposits

Moving beyond theoretical debates, ZKsync is demonstrating tangible institutional adoption through a partnership with digital asset custodian BitGo. The collaboration aims to create a full-stack infrastructure for tokenized deposits, combining BitGo’s custody services with ZKsync’s privacy-preserving Prividium network. The platform, currently in testing with regulated financial institutions, is designed to allow banks to issue and settle tokenized funds within existing regulatory boundaries.

This initiative directly addresses a major hurdle for institutional adoption: performing onchain transactions without exposing sensitive data on public networks. By enabling programmable payments that remain within the traditional banking system, the ZKsync and BitGo partnership provides a concrete example of how ZK technology can serve as a bridge between the innovation of public blockchains and the strict privacy and compliance requirements of traditional finance.
