ORDI

Overview

ORDI is the first token issued under the BRC-20 standard, an experimental token specification built on Bitcoin's Ordinals protocol and proposed in March 2023 by an anonymous developer known as domo. BRC-20 records token deployment, minting, and transfers by inscribing JSON-formatted text data onto individual satoshis. ORDI has a fixed total supply of 21 million tokens, all of which were distributed through open first-come, first-served minting with no presale or team allocation.

Unlike Ethereum's ERC-20, ORDI does not rely on smart contracts; balances and transfer history exist as inscriptions on Bitcoin that must be interpreted by off-chain indexers. This design means the protocol itself contains no execution logic and depends on consistent indexer implementations, a limitation often noted in technical discussions of BRC-20. ORDI was listed on major exchanges including Binance in late 2023, which brought broader attention to the Ordinals and BRC-20 ecosystem.
