Assets
Neurai inherits the asset layer of Ravencoin and extends it. Assets are tokens created and managed directly on Layer 1, with no smart contract: the node validates naming, supply, ownership and transfer rules as part of consensus. That makes them a natural fit for real-world assets, device identity and memberships.
What is an asset?
An asset is a named token that you create and control. When you issue one you decide:
| Property | Meaning | Limits |
|---|---|---|
| Name | Unique across the whole chain | 3 to 32 characters, uppercase letters, digits, . and _ |
| Quantity | Total supply | Up to 21,000,000,000 |
| Units | Decimal places | 0 to 8. Can be increased later, never decreased |
| Reissuable | Whether more can be minted later | Can be locked permanently |
| Metadata | Optional IPFS hash describing the asset | Updatable on reissue |
Creating an asset burns XNA. The burn is what keeps the namespace free of spam.
The namespace
Assets are organized like folders: one root name, and everything else hangs below it or belongs to a separate family.
Asset types
| Type | Looks like | Cost | Who can create it | What it is for |
|---|---|---|---|---|
| Root | COMPANY | 1,000 XNA | Anyone | Your brand, project or main identity. Unique on the chain |
| Owner token | COMPANY! | Free, automatic | Created with every root and sub-asset | The administrator key: reissue, create sub-assets, unique assets and channels |
| Sub-asset | COMPANY/PRODUCT | 200 XNA | Holder of COMPANY! | Categories, product lines, departments. Gets its own owner token |
| Unique asset | COMPANY#SERIAL_001 | 10 XNA | Holder of the parent owner token | NFTs and real-world items. Exactly one indivisible unit |
| Message channel | COMPANY~NEWS | 200 XNA | Holder of COMPANY! | Verifiable broadcast messages from the owner. Superseded by DePIN messaging |
| Qualifier | #KYC | 2,000 XNA | Anyone | A tag that can be attached to addresses |
| Sub-qualifier | #KYC/#EU | 200 XNA | Holder of #KYC! | Tiers inside a qualifier |
| Restricted | $COMPANY | 3,000 XNA | Holder of COMPANY! | Transferable only to addresses that satisfy a qualifier rule. Freezable |
| DePIN | &DEVICE | 10 XNA | Anyone | Soulbound identity and membership tokens with sections. Testnet and regtest for now |
Root and sub-assets
The root is the top of the tree and nobody else can use its name. Sub-assets live inside it and inherit the trust of the brand: if COMPANY is a game studio, COMPANY/GAME1 is clearly theirs. Both are fungible, can have decimals and can be reissued while the owner keeps that option open.
Owner tokens
Every root and sub-asset comes with an owner token ending in !. Whoever holds it can reissue, create sub-assets, unique assets and channels, change the metadata and lock reissuance. Transferring the owner token transfers full control of the project.
Never send an owner token unless you mean to hand over the project. A multisig address is a good place to keep it.
Unique assets
Unique assets are the NFTs of Neurai: one unit, indivisible, with an optional IPFS metadata hash. They are created under a root or sub-asset and land directly in the recipient's wallet. Typical uses are digital art, game items, tickets, certificates and one token per physical device.
Qualifiers and restricted assets
These are the compliance tools. A qualifier such as #KYC is a tag that its owner attaches to or removes from addresses for a small burn. A restricted asset such as $COMPANY carries a verifier expression, for example #KYC & !#BLOCKED, and can only be sent to addresses that satisfy it. The owner can freeze a single address or the whole asset. This is what tokenized securities and regulated real estate need.
DePIN assets
Introduced with POSITRONIC. A DePIN asset starts with & and is soulbound: holders cannot transfer it, only the owner token can, and a holder may burn its own unit. Sections such as &DEVICE/FLEET_A organize fleets or channels. The owner can freeze holders, and the asset doubles as the access key to a private, encrypted messaging channel. See Tokens and access.
Identity for devices
The same structure gives physical things an unforgeable identity:
- The manufacturer issues the root asset
MANUFACTURER. - Each product line gets a sub-asset,
MANUFACTURER/MODEL_X. - Each unit leaving the factory receives a unique asset,
MANUFACTURER#SN_0001, sent to the device's own address. - The device proves its origin by signing with that address, and anyone can check the chain to see who issued the token.
For fleets that also need private messaging and revocable membership, a DePIN asset per fleet is the modern alternative.
Naming rules
| Rule | Detail |
|---|---|
| Characters | A-Z, 0-9, . and _. Names are uppercase |
| Length | 3 to 32 characters including the owner mark. Testnet allows up to 120 |
| Separators | / sub-asset, # unique asset, ~ channel |
| Prefixes | # qualifier, $ restricted, & DePIN |
| Suffix | ! owner token |
| Reserved | Names that look like XNA, NEURAI or their variants cannot be issued |
Costs and burn addresses
Every issuance sends the burn amount to a type-specific address that nobody controls.
| Operation | Burn | Mainnet burn address |

| Issue DePIN asset | 10 XNA | Same as unique |
| Issue message channel | 200 XNA | NXissueMsgChanneLAssetXXXXXXTUzrtJ |
| Issue qualifier | 2,000 XNA | NXissueQuaLifierXXXXXXXXXXXXWurNcU |
| Issue sub-qualifier | 200 XNA | NXissueSubQuaLifierXXXXXXXXXV71vM3 |
