Solution Packs
Solution packs are the product-oriented reference patterns for Xian.
They are not full end-user products. They are narrow, opinionated examples that show how to use Xian as a Python-first decentralized backend for a real application shape.
Every pack should explain:
- the use case
- why Xian fits
- the contract set
- the Python integration surface
- the operator template and recovery story
Available Packs
Intended Progression
The initial pack set is:
- Credits Ledger Pack
- Registry / Approval Pack
- Workflow Backend Pack
The goal is to prove Xian through concrete backend patterns rather than generic toy contracts.
Today the deepest packs are:
- Credits Ledger, with a projected read model built from indexed chain events
- Registry / Approval, with an event-triggered projection hydrated from authoritative contract reads
- Workflow Backend, with separate processor and projector workers plus a projected queue/activity view
