In short
ORDI was created in 2023 as the first token minted under BRC-20, an experimental way of representing tokens on Bitcoin. It sits on top of Ordinals, a scheme that numbers Bitcoin's smallest units and inscribes data onto them. Bitcoin itself has no token functionality; balances are determined by off-chain indexers.
Key points
- Ordinals assigns serial numbers to satoshis, Bitcoin's smallest unit, and attaches data to them
- BRC-20 uses that mechanism to inscribe JSON text representing token operations
- Bitcoin's protocol does not recognise these tokens; balances come from how indexers interpret the inscriptions
- ORDI was the first BRC-20 mint, created to test the standard itself
Definition
The first token issued under BRC-20, a standard that represents tokens by inscribing JSON text via Bitcoin's Ordinals scheme.
Start with Ordinals. Published in January 2023, it assigns every satoshi a serial number in mining order and lets arbitrary data be embedded in a transaction spending that satoshi. The data goes into space made available by the Taproot upgrade, attaching images or text to individual satoshis. It changed none of Bitcoin's rules; it is a convention for using the existing ones.
BRC-20, proposed in March 2023, is an experiment on top of that. Operations — deploy, mint and transfer — are inscribed as JSON text, and balances are derived by reading those inscriptions in order. ORDI was the first ticker deployed, to see whether the standard worked at all.
Crucially, Bitcoin does not compute those balances. To a node these are just transactions carrying data. Who holds how much is decided by indexer software that reads the inscriptions in sequence. If indexer implementations disagree, so can the resulting balances; nothing is enforced automatically as a smart contract would be.
As the approach spread, inscriptions took up more Bitcoin block space and fees rose for a period. Whether block space should be used for non-payment data remains an open argument in the developer community.
Watch out for
- · Balance correctness depends on how indexers read the data; nothing is guaranteed by the protocol and implementations can diverge
- · Spending an inscribed satoshi as an ordinary payment can destroy the token attached to it, so handling it outside a compatible wallet is risky
- · BRC-20 has no built-in verification of supply or distribution, and many unrelated tokens simply copy well-known names
Frequently asked questions
Does this mean Bitcoin now supports smart contracts?
No. Ordinals and BRC-20 only write data into Bitcoin blocks; the protocol has no concept of tokens or executable logic. Aggregation and interpretation are done by software outside the chain.
