ARC-20 Tokens: Satoshi Backing, Minting, and Transfers on Bitcoin
Summary
ARC-20 is presented as a standard for fungible tokens on Bitcoin in which each token unit is linked to a satoshi. The article describes two issuance approaches: decentralized minting, where a creator sets parameters such as supply and start height, and direct minting, where the full supply is placed in one output. It also says token metadata and transfer history are carried with the token, supporting lineage that can be checked without relying on a separate indexer.
Under this model, transferring an ARC-20 token means transferring its associated satoshi through Bitcoin transactions. The article contrasts this with BRC-20 and claims ARC-20 transfers require no additional data to be written to Bitcoin, making them more efficient. However, it provides no technical references, measurements, fee comparisons, or independent assessment of these claims. Its discussion is an introductory description of the standard and its stated benefits, not evidence that token value is guaranteed or that every implementation has the described properties.
Key ideas
- Each ARC-20 unit is associated with at least one satoshi on Bitcoin.
- Decentralized minting allows a project creator to specify issuance parameters.
- Direct minting creates an output containing the token supply, with satoshis representing units.
- The article says token lineage and metadata travel with the asset rather than depending on an indexer.
- It claims ARC-20 transfers avoid extra data inscription, but provides no supporting measurements.
