Permissionless
Open to anyone to use or participate without needing approval from a central authority.
Permissionless systems allow anyone to join, transact, or validate without whitelists. In Bitcoin Cash and similar networks, anyone can run a node, create a wallet, or mine.
Openness improves resilience and innovation but complicates compliance and can attract spam or abuse, mitigated by fees and economic incentives.
