# Cyberia

Cyberia is a real-time tap-based sandbox MMORPG and the tooling that produces it. It is one
product on the platform: it consumes canonical content from Object Layer and settles economic
questions with ItemLedger and CryptoKoyn, and it owns everything that makes the game a game.

## Purpose

Cyberia turns canonical definitions into a world: maps, entities, quests, actions and the
runtime that simulates them for connected players.

## Responsibilities

| Cyberia owns                                                  | Cyberia does not own                           |
| ------------------------------------------------------------- | ---------------------------------------------- |
| The game runtime: simulation, presentation and the data layer | Canonical definitions, which Object Layer owns |
| The Game Studio and the authoring workflow                    | Content identity, which Object Layer computes  |
| The Cyberia Engine and the Cyberia CLI                        | On-chain registration, which ItemLedger owns   |
| World content, item label bindings and content releases       | CKY and balances, which CryptoKoyn owns        |
| Player progress: inventory, quests, coin balance              | Item ownership, which is chain state           |

## Boundaries

Cyberia authors Object Layer content through the Studio, but the canonical copy is always
written at the Object Layer authority; Cyberia keeps a draft or a cache copy and binds a label
to it. Progress never moves on chain, and ownership never becomes a Cyberia source of truth.

## Current maturity

Open Alpha. The three processes run, content is authored and released, and the economy is
off-chain. On-chain ownership belongs to a later phase.
