ChainThink News, May 13: According to an official announcement, Polygon has announced the completion of a privacy enhancement upgrade to Polygon CDK, introducing a new Validium configuration based on the Succinct SP1 Hypercube zero-knowledge proof system.

This configuration enables institutions to retain original transaction data within their own infrastructure, submitting only cryptographic commitments and zero-knowledge proofs to Ethereum, achieving "private data, public verification," while maintaining liquidity interoperability with Ethereum and other chains through AggLayer.

The upgrade offers five composability-focused privacy tiers, covering permissioned access, confidential chains (Validium), trusted execution environments (TEE), fully homomorphic encryption tokens (FHE), and client-side zero-knowledge private transactions, supporting integration with enterprise identity systems such as Okta and Azure AD, primarily targeting traditional financial institutions including banks, payment providers, and asset management firms planning to migrate on-chain.
