A **permissionless** system is one that does not require permission to participate. Examples include certain [open platforms](https://metavert.io/open-platform), many [blockchain](https://metavert.io/blockchain) protocols, and most [decentralized](https://metavert.io/decentralization) systems; this is in contrast to [walled gardens](https://metavert.io/walled-garden) that control who is able to participate and what they are allowed to do.
