How Does a Permissioned Chain Handle Data Privacy Compared to a Public Chain?

A permissioned chain offers superior data privacy compared to a public chain. Public chains expose all transaction data to everyone.

Permissioned chains use access control lists and often employ privacy-enhancing technologies like zero-knowledge proofs or private channels (e.g. Hyperledger Fabric channels).

This allows organizations to share necessary data with authorized parties only, keeping sensitive financial or client data confidential while still benefiting from a shared, immutable ledger.
