BRC-20 Tokens

Key points

• BRC-20 is an experimental standard that allows fungible tokens to be created directly on the Bitcoin network.
• It relies on the Ordinals protocol, which inscribes data on small units of the currency, recording the token's information on the blockchain itself.
• It is a simple, limited approach, quite different from token standards on networks designed for smart contracts.

What are BRC-20 tokens?

BRC-20 tokens are fungible tokens created on the Bitcoin network through an experimental standard of the same name. Historically, the Bitcoin network was designed to transfer its own currency, not to host other tokens. BRC-20 emerged as an ingenious way to work around this limitation, using a mechanism that writes information directly to the blockchain.

How it works

The standard relies on the Ordinals protocol, which allows data to be inscribed on minimal units of the network's currency. In the case of BRC-20, these inscriptions contain text-based instructions that define the creation of a token, its supply, and transfers between participants. Instead of a smart contract controlling the token, it is these inscriptions recorded on the blockchain that describe its state.

This approach is deliberately simple and has clear limitations. Unlike standards on networks built for smart contracts, BRC-20 does not offer sophisticated programmable logic; it only records creation and transfers in a basic way. Interpreting what these inscriptions mean depends on external tools, since the network itself does not understand the concept of a token the same way networks designed for that purpose do.

The standard emerged experimentally and quickly gained attention, generating a large volume of inscriptions. This sparked debates within the community, because this use occupies space on the blockchain and competes with regular transfers, which can push up fees during periods of high demand. Some see BRC-20 as creative innovation, while others consider it a deviation from the network's original purpose.

Being experimental, the standard continues to evolve and carries significant technical uncertainties.

Why it matters

Understanding BRC-20 helps you follow one of the most visible debates about using the Bitcoin network beyond its currency. Knowing that it is an experimental and limited standard helps set realistic expectations. This is a technical concept, and none of it represents any recommendation to trade any asset.

Risks and limitations

BRC-20 is experimental, technically limited, and depends on external tools to be interpreted, which increases the chance of errors. Its intensive use can congest the network and raise fees. Being recent and not very mature, it carries significant uncertainty, and the simplicity of the standard greatly restricts what these tokens can do.
