Decentralization vs Permissionless

Decentralization is the distribution of authority, control, and decision-making away from a central entity across a network of participants. In cryptocurrency, it refers to blockchain systems operating without central control, where network participants collectively validate transactions and maintain security.

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.
