C‐BRC‐20

• Operations
  • Deploy
  • Mint & Transfer

Nowadays, people are crazy about minting inscriptions on Bitcoin. However, most inscriptions they mint are BRC-20 tokens, which use an application protocol based on the original inscription protocol. Minting BRC-20 tokens on Bitcoin is so appealing because of its fairness and narratives. All participants must pay a fee to mint and follow the transaction ordering rules on the chain.

Unlike BRC-20, C-BRC-20 currently only needs two operations: deploy and mint. The "deploy" operation means creating a new C-BRC-20 token. The "mint" operation means minting a C-BRC-20 token. After the inscription of the "mint" operation is revealed on Bitcoin, it will be locked and can only be transferred on the circulating chain.

Operations

Deploy

First, A "deploy" operation is required to deploy a new C-BRC-20 token. After deploying the token on Bitcoin, it can be minted on Bitcoin.

{
  "p": "c-brc-20",
  "op": "deploy",
  "tick": "c-ins",
  "max": "21000000",
  "lim": "1000",
  "dec": "...."
}

Key	Required?	Full Name	Description
p	Yes	Protocol	Identifier of the protocol.
op	Yes	Operation	Types of operation.
tick	Yes	Ticker	The token name has no length limit and can be duplicated. Characters should be limited to 0-9a-z and -.
max	Yes	Max supply	Total supply of the token.
lim	No	Mint limit	Output limit for each minting.
dec	No	Decimals	Decimals, the default value is 18.

Mint & Transfer

These actions should be implemented on a circulating chain using a smart contract. There is no limit to the detail in the implementation, but C-INS does have some recommended practices:

• The contract should be capable of storing the Inscription ID on Bitcoin and providing an API for retrieval.
• The minting process should be as fair as possible.
