- privacy: limited to a set of users
- secret: unknown to others who aren’t in on the encryption
Because Noosphere is a decentralized service (e.g. we expect other providers), privacy requires secrecy via E2EE.
In a centralized service (Discord), you could have privacy wherein random people can’t view your content, but the discord admins could view it (not secret).
In a decentralized service, your envelope of trust expands to the union of all providers (both now and in the future). This means that in a group of 3 people with a shared note, person 1 needs to trust the providers of 2 and 3, now and in the future. This isn’t very tenable.
