BRC: Blacklist Request for Comment

Overview

BRC is the official smart contract standard for the Blacklist Network, the first Bitcoin Layer 2 to support channels, smart contracts, invoices, and NFTs. Inspired by Ethereum's ERC-721, BRC goes further by integrating Blacklist payments, automatic royalties, and payment streaming, fostering a robust ecosystem for digital assets and smart contracts on the Bitcoin network.

Modular Structure

All BRC standards are implemented as internal modules of a single crate. This means you only need to add one dependency, and you have access to all standards through the main brc crate:

• brc002: Payment channels and channel states
• brc003: Smart contracts and terms
• brc004: Payment invoices
• brc005: NFT structures, events, traits, validation, payments, and royalties
• brc006: (Describe what this module does here)
• validation: (Describe what this module does here, if public)

The main crate (brc) re-exports all modules, providing centralized access:

use brc::brc002::*;
use brc::brc003::*;
use brc::brc004::*;
use brc::brc005::*;
use brc::brc006::*;
// use brc::validation::*; // Se for público

Installation

Add to your Cargo.toml:

[dependencies]
brc = "0.0.1"

Note: For local development, simply clone the repository and edit the code directly. No need to use path dependencies, as all modules are internal.

Usage Example

use brc::brc005::{BRCToken, BRCMintRequest, MintBRC};

struct MyNFTContract;

impl MintBRC for MyNFTContract {
    fn mint(&self, req: &BRCMintRequest) -> BRCToken {
        // Custom implementation
    }
}

Features

• Standardized NFTs: Structures and events compatible with wallets, marketplaces, and dApps.
• Blacklist Payments: Minting, transfers, and royalties via Blacklist invoices.
• Payment Streaming: Native support for recurring payments (sats/second).
• Automatic Royalties: Configurable percentages, including for secondary sales.
• Traceable Events: Full audit of operations (mint, transfer, approval, payments, streams).
• Modular structure: Each BRC standard is an internal module, making maintenance and extensibility easier.

Use Cases

• Minting and transferring NFTs with Blacklist payment integration.
• NFTs with recurring payments (subscriptions, licenses).
• Automatic royalties for creators on primary and secondary sales.
• Integration with dApps, wallets, and marketplaces on the Blacklist Network.
