The relay

The relay is designed to check signatures and membership, append signed, encrypted changes to a space’s log and hand them out from a cursor. It holds no keys and folds nothing, so it cannot read content.

What it does see. Which key is in which space, when and how much each key writes, the key generations and when they change, the rhythm of work, and who reads which space from where. It can also withhold changes or show members different subsets of a log.
