Institutional Blockchain Privacy in 2026: Selective Disclosure with Aztec, ZKsync, and Canton Network

Public blockchains expose every wallet balance and counterparty by default—a non-starter for banks and asset managers. In 2026, institutional blockchain privacy has moved past “dark pools” toward selective disclosure (“verification without revelation”), allowing firms to prove compliance or solvency without exposing proprietary positions (ChainSafe).

Leading 2026 Privacy Approaches Compared

• Aztec Network: A privacy-by-default Ethereum Layer 2 using a Hybrid State model so private and public smart contracts interoperate (ChainSafe).
• ZKsync Hyperchains: Modular, interoperable ZK-chains offering “Privacy-on-Demand” via validiums for institutional deployments (ChainSafe).
• Canton Network: A public network engineered for regulated markets with sub-transaction privacy and EVM compatibility via ERC-20/CIP-56 middleware (ChainSafe).
• zkVerify: A universal proof-verification layer lowering the cost of verifying ZK proofs on public ledgers (ChainSafe).

Frequently Asked Questions

What is selective disclosure in blockchain?

It uses zero-knowledge proofs to prove a rule is satisfied (e.g., Proof of Reserves or KYC eligibility) without revealing the underlying balances or identity (ChainSafe).
