BRC-20 Protocol in Bitcoin Ecosystem

Background: Bitcoin's UTXO Mechanism

Bitcoin's UTXO (Unspent Transaction Output) mechanism makes each satoshi (smallest unit) traceable and non-homogeneous, enabling protocols like BRC-20, ORC-20, and BRC-21. This supports innovations such as Bitcoin NFTs and BTC domains, fostering ecosystem growth.

BRC-20 Overview

BRC-20 is based on the Ordinals protocol and serves as a standard for deploying and transferring homogenized tokens on Bitcoin. Unlike ERC-20, it uses JSON-formatted inscriptions, treating tokens as annotated satoshis. Deployment follows a "first-is-first" principle, ensuring fairness but limiting capabilities due to Bitcoin's lack of smart contracts.

Comparison with ERC-20

BRC-20 differs from ERC-20 as it is not a digital account system but a ledger entry, lacking advanced features like DeFi applications. ERC-20 enables complex scenarios on Ethereum, while BRC-20 remains largely meme-driven due to Bitcoin's constraints.

Current State: Meme-driven and Ecosystem Impact

BRC-20, inspired by user experiments in 2023, has seen rapid growth, with over 50,000 tokens deployed as of November 2023. Key tokens like ordi exhibit high volatility, driven by speculation rather than utility. This surge boosts Bitcoin transaction volume and fees, advancing NFT and domain ecosystems.

New Protocols: ORC-20 and BRC-21

ORC-20 addresses BRC-20's limitations by improving security, preventing double-spending, and enhancing interoperability. BRC-21 acts as a cross-chain anchor, mapping external assets to Bitcoin. However, Bitcoin still lacks native DeFi innovations like ERC-20 standard.

Comparison with Ethereum and Polygon

BRC-20 on Bitcoin parallels Ethereum's ERC-20, but Polygon introduced PRC-20 (inspired by BRC-20) in late 2023, increasing chain transactions and token minting. This cross-chain innovation shows similarities but lacks Bitcoin's unique satoshi traits.

Risks and Outlook

BRC-20's hype may not translate to sustainable innovation, driven by speculative Meme tokens. Regulatory uncertainties and slower DeFi innovation peritonate development. Further ecosystem growth requires Bitcoin-specific original innovations, similar to Ethereum's role.
