解释：

C is correct. The underlying processes for distributed ledger technology generally require massive amounts of energy to verify transaction activity.

A is incorrect. The fact that distributed ledger technology can be shared across a network is one of its desirable features.

B is incorrect. The consensus mechanism enables the creation of records that are, for the most part, considered immutable, or unchangeable, yet they are transparent and accessible to network participants on a nearly real-time basis.
