# CBRC-20

## What is Cy\[bord] CBRC-20? <a href="#what-is-cy-bord-cbrc-20" id="what-is-cy-bord-cbrc-20"></a>

### Introduction  <a href="#introduction" id="introduction"></a>

Cy\[bord] CBRC-20 is the proposal of an efficient Metaprotocol standard for fungible tokens on Bitcoin through Ordinals. By utilizing the new **`metadata`** and **`metaprotocol`** fields introduced in ord 0.10+, which allow for arbitrary properties to be stored directly within the Inscription envelope, CBRC-20 keeps the same functional logic of the BRC-20 Metaprotocol while reducing the cost of each inscription and simplifying the indexing process.

#### Overview of CBRC-20 Features <a href="#overview-of-cbrc-20-features" id="overview-of-cbrc-20-features"></a>

* **Reduced Inscription Costs**: CBRC-20 lowers the cost per inscription for token deploy, mint, and transfer operations compared to BRC-20/TAP.
* **Simplified Indexing**: CBRC-20 provides a simple way to index the CBRC-20 Metaprotocol state due to all information being directly available in the envelope of each Inscription.
* **Flexibility with MIME Types**: The CBRC-20 standard allows for any MIME type to be used for deploying, minting, or transferring CBRC-20 tokens.
  * **Examples**:
    * Deploying, minting, or transferring any CBRC-20 token can be done by simply inscribing the number "0" as a text file, reducing the inscription cost by 10 times compared to other Metaprotocol Ordinal Token Standards.
    * Deploying a CBRC-20 token and allowing users to "mint" as part of a PFP collection, with a specific number of tokens minted on each image. These tokens can then be transferred like any other CBRC-20 token (on a new transfer inscription), *without* sending the image the tokens were minted on.
    * The potential applications are endless and unexplored!
* **No Limitations of Ord 0.9**: Unlike previous standards, CBRC-20 is not constrained by the "freeze" of Ordinals version 0.9 and can utilize the latest features of the ord client.
