Introduction
BRC-201 proposes an extension protocol to the BRC-20 standard. It is aimed to be backward compatible with BRC-20, to improve scalability, especially to bridge BRC-20 tokens to chains with smart contract support, such as Ethereum, BNB Chain, Near, etc.
Ordinals and BRC-20
imbues satoshis with numismatic value, allowing them to be collected and traded as curios. Individual satoshis can be inscribed with arbitrary content, creating unique Bitcoin-native digital artifacts that can be held in Bitcoin wallets and transferred using Bitcoin transactions.
is experimental token standard by Domo. Tokens can be deployed, minted, and transferred using Ordinal inscriptions.
Definition
BRC-201 is an extension of the BRC-20 token standard that enhances the Transfer operation. This extension remains compatible with the BRC-20 protocol.
BRC-20 token transfer looks like this:
BRC-201 extend operation looks like this:
BRC-201 introduces three additional fields: "chain", "ext", and "ref".
If an indexer does not support the BRC-201 protocol, the transaction will be treated as a regular transfer operation.
However, an enhanced indexer that supports BRC-201 can parse additional extension operations.
Currently, the BRC-201 specification defines "Bridge In" and "Bridge Out" as extension operations.
