BRC-20 is an experimental token standard for the [[Bitcoin]] blockchain, allowing users to create and transfer fungible tokens. Think of it like a blueprint for making tokens on Bitcoin, similar to how [[ERC-20]] tokens work on Ethereum. It was created by an anonymous on-chain analyst named Domo in March 2023 and utilizes Ordinals inscriptions, which essentially let you attach data to individual satoshis (the smallest unit of Bitcoin). This allows for the creation of tokens that represent anything from memecoins to more serious projects. However, it's important to remember that BRC-20 is still experimental and has limitations compared to other token standards.
