What is the BRC-20 standard?
BRC-20 is a fungible token standard proposed by pseudonymous developer “domo” in March 2023, built on top of Bitcoin Ordinals. The standard uses inscribed JSON text to define token operations: “deploy” creates a new token with name and supply; “mint” allows users to create tokens up to the supply cap; “transfer” moves tokens between addresses. The first BRC-20 token, ORDI, reached USD 1B+ market cap within months.
How BRC-20 mechanically works
Three operations. (1) Deploy — inscribed JSON specifies token ticker (4 characters), maximum supply, and mint limit per transaction. (2) Mint — inscribers create tokens by inscribing mint operations until supply is exhausted; first-mover advantage on minting. (3) Transfer — inscribed transfer operations move tokens between Bitcoin addresses, requiring off-chain indexers to track state. BRC-20 has no smart-contract execution — all state interpretation happens off-chain.
Why BRC-20 is controversial
Three structural critiques. (1) Off-chain dependency — token state requires trusted indexers; Bitcoin nodes don’t validate BRC-20 semantics. (2) Block-space consumption — BRC-20 minting drove Bitcoin transaction fees to multi-year highs in 2023-2024. (3) Meme-economic dynamics — most BRC-20 tokens have no fundamental utility; pure speculation drives valuations. Vitalik Buterin and others have noted BRC-20 resembles ICO-era token issuance without the smart contract automation.
The market
BRC-20 market peaked in mid-2023 with USD 5B+ combined market cap. ORDI dominates the category; other notable tokens include SATS, MUBI, OXBT. Trading happens primarily on Unisat, OKX, and Magic Eden’s Ordinals marketplace. The category has subsequently consolidated, with most early tokens losing 80%+ value as speculation cooled.
Regulatory positioning
BRC-20 tokens face similar securities scrutiny as ICO-era ERC-20 tokens — potentially classified as investment contracts under Howey test depending on issuer marketing and reasonable expectation of profit. EU MiCA treats BRC-20 as utility tokens or asset-referenced tokens depending on backing. Türkiye’s CASP framework would treat BRC-20 listing on Türk exchanges as crypto-asset service activity.
Türkiye context
Türk crypto traders attracted to BRC-20 speculation should understand the off-chain validation risk: a single indexer disagreement could split token state. CASP-licensed Türk exchanges listing BRC-20 tokens require explicit risk disclosure about the non-standard architecture.

How BRC-20 differs legally and technically
Unlike ERC-20 tokens, which are governed by smart-contract logic on Ethereum, BRC-20 tokens are created by “inscribing” data onto individual satoshis using the Ordinals protocol on Bitcoin. There is no smart contract enforcing supply, transfers or permissions — the standard is essentially a shared convention interpreted by off-chain indexers. That has two consequences for lawyers. First, functionality that ERC-20 issuers take for granted (vesting locks, allow-lists, upgradeability) cannot be encoded at the token level, so contractual and operational controls must carry more weight. Second, the regulatory characterisation still turns on economic substance, not the technical standard: a BRC-20 token marketed with profit expectations can be a security or a regulated crypto-asset just as an ERC-20 token can, despite the absence of a smart contract.
