What are BRC-20 Tokens?

The BRC-20 token standard represents an intriguing milestone in the realm of cryptocurrency. Launched by Twitter user @domodata on March 8th, 2023, BRC-20 tokens have quickly gained attention within the crypto community. Despite sharing a similar name with Ethereum's ERC-20 token standard, BRC-20 is quite distinct, both in its mechanism and purpose.

Understanding BRC-20 Tokens

BRC-20 is a fungible token standard developed specifically for the Bitcoin blockchain. It uses Ordinal inscriptions of JavaScript Object Notation (JSON) to deploy token contracts, mint, and transfer tokens. In essence, it's a way to attach a script file to bitcoin and use that file to attribute tokens to satoshis, the smallest unit of Bitcoin. These tokens can then be transferred from one user to another.

Unlike the token standards on EVM (Ethereum Virtual Machine) chains, which deploy smart contracts to govern token standards and rules, BRC-20 doesn't interact with smart contracts. Instead, BRC-20 tokens rely on the underlying Bitcoin protocol, utilizing its proof-of-work mechanism for operations.

The BRC-20 token standard uses JSON inscriptions on satoshis to create tokens. JSON, a lightweight data-interchange format, houses executable code bits that define every aspect of the token, including supply, minting limit, and the token's identity. Once successfully deployed, any Bitcoin ordinal wallet can connect to the network, mint the token, and transact with it like any other cryptocurrency.

Although BRC-20 tokens might seem similar to smart contract tokens, they possess an essential difference. While smart contracts allow the conditions to be changed, BRC-20 inscriptions are immutable, being directly inscribed to a satoshi, they cannot be modified by any counterparty.

Advantages of BRC-20 Tokens

BRC-20 tokens, although in their early stages, offer several notable benefits.

  • Fungibility: BRC-20 tokens are fungible, meaning they are interchangeable and can be easily traded on exchanges. This presents an opportunity to interact with the Bitcoin blockchain without necessarily trading Bitcoin itself.

  • Security: Being built on the Bitcoin protocol, BRC-20 tokens inherit the high level of security and resistance to hacking attempts characteristic of Bitcoin.

  • Compatibility: BRC-20 tokens integrate seamlessly with the Bitcoin protocol, which means they can be easily assimilated into the Bitcoin ecosystem.

  • Decentralization: Benefiting from Bitcoin's decentralized network, BRC-20 tokens can be sent between peers just like any other cryptocurrency.

BRC-20 vs. ERC-20 Tokens

While both BRC-20 and ERC-20 tokens run on a parent blockchain network, they differ significantly in their mechanisms and features.ERC-20 tokens are created through a smart contract code written in languages such as Solidity and deployed on the Ethereum Virtual Machine. In contrast, BRC-20 tokens are created through ordinal inscriptions on satoshis using JSON. Unlike BRC-20 tokens that operate parallel to Bitcoin, activities on the ERC-20 protocol are in sync with the Ethereum network. Also, the distribution of ERC-20 tokens can be centrally managed by a single entity, which can lead to potential manipulation, while BRC-20 tokens foster a more decentralized and inclusive token generation process.

In summary, BRC-20 represents a unique approach to fungible tokens on the Bitcoin blockchain. While they don't have the ability to interact with smart contracts like the Ethereum-based ERC-20 tokens, BRC-20 tokens provide a secure, fungible, and decentralized alternative for tokenization on the Bitcoin network. As the Bitcoin ecosystem continues to evolve, it will be exciting to see how BRC-20 tokens and similar innovations contribute to the blockchain's future.
