Namespace​
Another core feature made available by Sirius technology is the ability to generate Namespaces, the blockchain equivalent to a website domain. It is a unique place to link your game company, its games, and tokens (SDAs) on the blockchain. It is necessary for game onboarding as it enables gamers to verify their tokens' authenticity easily and for systems to read off the blockchain and display recognizable names.
A Namespace (root Namespace) can be created with a custom name that must appear as unique in the network, and may have a maximum length of 64 characters. Allowed characters are a, b, c, …, z, 0, 1, 2, …, 9, _ , -.(Excluding capital letters and special characters)
Additionally, a Namespace (root Namespace) can have multiple linked sub-Namespaces with multiple underlying tiers. You can configure your Namespace setup as follows:
- Tier 1: Root namespace: [company or developer name]
- Tier 2: Sub namespace: [game name]
- Tier 3: Multiple sub-namespace: [game tokens]
See the diagram below.

ProximaX Sirius Wallet​
Blockchain wallet that holds blockchain account(s).
An blockchain account is represented by a key pair (private and public key) associated with a mutable state stored on the Sirius Chain. In other words, you have a deposit box, which only you can modify with your private key.
Think of an account as container for assets. It can be used to hold XPX or other SDAs, whether they are tokens or specialized assets.
Moreover, Sirius Chain accounts can also represent non-fungible assets that must be unique and updatable: a package to be shipped, a house deed or a document to be notarized.
Each account has a unique address. You will normally share the derived address instead, as it is shorter and gathers more information.
