Overview

Package corerepo provides pinning and garbage collection for local IPFS block services.

IPFS nodes will keep local copies of any object that have either been added or requested locally. Not all of these objects are worth preserving forever though, so the node adminstrator can pin objects they want to keep and unpin objects that they don't care about.

Garbage collection sweeps iterate through the local block store removing objects that aren't pinned, which frees storage space for new objects.
