BRC-20
Also known as: Bitcoin Fungible Token, Ordinal Token Standard, BRC Ordinal Standard
An experimental token standard for Bitcoin using Ordinals to inscribe fungible tokens onto satoshis.
BRC-20 is a token standard built on the Bitcoin blockchain, enabling the creation and transfer of fungible tokens using Ordinal inscriptions. Inspired by Ethereum's ERC-20, BRC-20 tokens are not natively supported by the Bitcoin protocol, but use JSON-based inscriptions encoded on satoshis. This innovation allows for on-chain token metadata without requiring smart contracts. BRC-20 gained attention for meme tokens and experiments, but also sparked debates on scalability and spam. Tools like Unisat help mint and trade BRC-20 tokens, though adoption remains early-stage.
