Permissioned vs Permissionless

Permissioned refers to blockchain networks or systems where access, participation, and specific actions require explicit authorization from a controlling authority. Participants must be granted permission before they can join, validate transactions, or access network data.

Permissionless means anyone can participate in a blockchain network without requiring approval from any authority. Users can join, transact, validate, and build applications freely without gatekeepers controlling access or censoring participation.
