In the definition for ion it has mentioned as permissionless

What is mean by permissionless?

[csuwildcat]

Permissionless in ION means as long as you can run an ION node, which only relies on Bitcoin working and being able to expose data CIDs to IPFS peers, you can use/write to/interact with the ION network. Because ION is really just some Bitcoin + IPFS + some local processing logic, there's no one to permission, authorize, or dictate use, you are just using a protocol composed of completely open systems and basic logic your computer runs.
