In the proof of stake blockchain, the appending entities are named minters or validators (in the proof of work blockchains this task is carried out by the miners); [2] in most protocols, the validators receive a reward for doing so.

Miners compete to solve crypto challenges on the bitcoin blockchain, and their solutions must be agreed upon by all nodes and reach consensus. The solutions are then used to validate transactions, add blocks and generate new bitcoins. Miners are rewarded for solving these puzzles and successfully adding new blocks.
Blockchain has been acknowledged as a way to solve fair information practices, a set of principles relating to privacy practices and concerns for users.
