Architecture
- How to read this
- Each floor is one level, from the chain at the bottom to people at the top.
- Each tile is one part. Click it to read what it does.
- A dashed outline is a part that comes later.
- Host network, left: how the levels reach each other through the host.
- Chain facts, right: what the chain records, and which parts rely on it.
- Colour shows the level. Batches recolours parts by when they ship.
- Journeys, along the bottom, play one task step by step across the stack.
