Singletokens

Singletokens are a class of digital tokens on distributed ledgers designed to represent a single, indivisible unit of value, asset entitlement, or credential. Each singletoken has a unique identifier and cannot be subdivided or merged with another token, unlike fungible tokens that are interchangeable and divisible. Singletokens are commonly implemented using non-fungible token (NFT) standards or by configuring token contracts to enforce a zero decimal place and a fixed supply.

Origin and purpose: The concept arose in tokenization discussions where precise one-to-one mapping to a single asset or entitlement was required. Use cases include certificates of authenticity, event tickets, rare digital collectibles, or proofs of ownership for physical assets. Singletokens help maintain provenance and provide a simple auditable transfer history.

Technical characteristics: Singletokens carry asset metadata such as issuer, issue date, serial number, and provenance. They rely on smart contracts to enforce indivisibility and transfer rights, and may be minted individually or in batches with each unit bearing a distinct token ID. Interoperability depends on adopting standard interfaces (for example, NFT standards) and compatible wallets and marketplaces.

Applications: They are used for digital certificates, tickets, title proofs, collectible items, and other single-use or single-ownership entitlements. In governance contexts, a singletoken can denote a single voting right or a discrete entitlement tied to a specific decision.

Limitations and considerations: Indivisibility can reduce liquidity and complicate fractional ownership. Security relies on safe custody and robust contract design. Environmental impact depends on the underlying blockchain, and some critics argue that singletokens duplicate existing non-fungible token models rather than offering a distinct paradigm.
