How Is Data Privacy Maintained on an Immutable Ledger That Is Also Used for Regulatory Audits?

Privacy is maintained through a combination of techniques, primarily encryption and permissioning. Data can be encrypted before being written to the ledger, so only authorized parties with the correct decryption key can view the sensitive details.

Furthermore, private blockchains are permissioned, meaning access to the ledger itself is restricted, and regulators are typically granted only read-only access to specific, necessary data sets, not the entire, raw transaction history.
