Data is the raw commodity for digital scoiety and human attention is the scarce resource.

# Journals

Journals are end-user encrypted append-only logs stored on IPFS. Journals build on Textile ThreadsDB (which provides logs with a layered encryption schema).

For convenience we will label a collection of journals controlled by a single entity an identity, but note that this label is only visible to the entity.

Journals are built on a permissioning system that is controlled by the end-users. This open protocol, User-Controlled Access Networks ("UCANs"), is designed to handle service authorization without a centralised backend. The design is led by Fission (see an intro [blog](https://fission.codes/blog/auth-without-backend/)).
