What Is the Token ID Structure for a Semi-Fungible Asset?
In ERC-1155, the token ID is a 256-bit integer that is typically structured to encode both the asset's type and its unique characteristics, such as its expiration date or specific class. For a semi-fungible asset, the ID might encode the fungible batch information (e.g. all tickets for a specific date) and later, a unique serial number to mark its non-fungible state.

Characteristic ⎊ Non-fungible describes an asset whose individual units are unique and cannot be mutually substituted, meaning each unit possesses distinct properties, history, and value.
Unique Serial Number
Number ⎊ A unique serial number is a distinct identifier assigned to a specific asset or entity, guaranteeing its non-fungibility.
Fungible Batch Information
Provenance ⎊ Fungible Batch Information, within cryptocurrency and derivatives, denotes a verifiable history of an asset’s origin and custody, crucial for establishing trust in decentralized systems.
Token Id Structure
Identifier ⎊ The token ID structure defines the unique, immutable identifier assigned to every digital asset or tokenized derivative on a distributed ledger, serving as the definitive on-chain proof of existence and ownership.
