A Complete Guide to ARC-20 and Atomicals: New Applications on the Bitcoin Blockchain

·

The Bitcoin blockchain continues to evolve beyond simple peer-to-peer transactions. While Bitcoin itself and Ordinals inscriptions have gained significant attention, new protocols are expanding the network’s utility. Among these innovations, ARC-20 introduces a fungible token standard that leverages Bitcoin’s smallest unit—the satoshi—to represent digital assets. This approach ensures each token is backed by a satoshi, providing inherent value and seamless integration with existing Bitcoin infrastructure.

At the same time, the Atomicals protocol offers a novel method for representing both fungible and non-fungible assets on-chain. Together, these developments unlock new possibilities for tokenization, digital ownership, and decentralized finance on Bitcoin. This guide explores the fundamentals of ARC-20 tokens, their minting processes, and how they compare to other Bitcoin-based token standards.

Understanding ARC-20 Tokens on the Bitcoin Blockchain

ARC-20 represents a significant leap in Bitcoin’s tokenization capabilities. Unlike other token standards that operate on separate layers or sidechains, ARC-20 is native to Bitcoin. Each ARC-20 token is directly tied to one satoshi, the smallest denomination of Bitcoin. This design ensures that every token has a baseline value equivalent to 1/100,000,000 of a Bitcoin, combining the security of Bitcoin with the flexibility of digital tokens.

This token standard supports a wide range of use cases, from custom currencies and reward points to asset-backed tokens. Because ARC-20 tokens are built on satoshis, they benefit from Bitcoin’s robust network effects, security model, and widespread infrastructure. Wallets like Sparrow Wallet and others that support Bitcoin naturally can hold and transfer ARC-20 tokens, making them highly accessible.

Moreover, the protocol includes a global naming system for token tickers. Once a ticker is registered, it is permanently reserved, preventing duplication and ensuring clarity within the ecosystem. This feature simplifies token discovery and reduces the risk of confusion or fraud.

How ARC-20 Tokens Work: The Minting Process Explained

The creation of ARC-20 tokens, known as minting, involves embedding token information onto individual satoshis. This process ensures that each token is uniquely identifiable and securely backed by Bitcoin’s blockchain. The protocol supports two primary minting methods: decentralized and direct minting, each with distinct advantages.

In decentralized minting, the token creator initializes the token by setting parameters such as the ticker symbol, total supply, minting reward, and starting block height. This method allows for a controlled, gradual distribution of tokens, similar to a fair launch. Participants can mint tokens by contributing computational work, ensuring a decentralized and permissionless process.

Direct minting, on the other hand, involves creating the entire token supply in a single transaction. The creator locks a quantity of satoshis equal to the token supply, with each satoshi representing one token. This method is efficient and straightforward, ideal for projects that require immediate liquidity or centralized distribution control.

Both methods leverage the security and immutability of the Bitcoin blockchain. Once minted, ARC-20 tokens can be transferred using standard Bitcoin transactions, ensuring compatibility with existing tools and services.

Comparing Minting Methods: Decentralized vs. Direct Minting

Choosing the right minting method depends on the project’s goals, distribution strategy, and desired level of decentralization. Here’s a detailed comparison of the two approaches:

Decentralized Minting

Decentralized minting is designed for community-driven projects. It involves several key steps:

  1. Initialization: The deployer sets the token parameters, including the ticker, total supply, and start block.
  2. Customization: Metadata such as descriptions or images can be added to provide context about the token.
  3. Command Execution: Using the Atomicals CLI, the deployer runs commands like npm run cli init-dft to initialize the token.
  4. Gradual Distribution: Minting occurs over time, allowing broad participation and reducing centralization.

This method is ideal for tokens aiming for fair distribution and community engagement.

Direct Minting

Direct minting offers a streamlined approach:

  1. Single Transaction: The entire token supply is created in one operation, with each satoshi representing one token.
  2. Security: The creator must lock Bitcoin equal to the token’s value, ensuring transparency and reducing fraud risk.
  3. Efficiency: Commands like npm run cli mint-ft enable quick deployment, suitable for time-sensitive projects.
  4. Control: Ideal for teams requiring full oversight over token distribution and use cases.

Direct minting provides speed and simplicity, making it a popular choice for enterprise applications.

Step-by-Step Guide to Decentralized Minting of ARC-20 Tokens

For those interested in decentralized minting, the process is broken into two main phases: initialization and minting. Here’s a step-by-step overview:

Phase 1: Initialization

  1. Setup: Define the token’s unique ticker, minting reward, total supply, and start block height.
  2. Command: Use the Atomicals CLI to execute npm run cli init-dft metadata.json.
  3. Custom Flags: Optionally, include flags like --mintbitworkc for proof-of-work requirements or --satsbyte to set transaction fees.
  4. Metadata: Add descriptive details, such as the token’s purpose, image, or official links, to the metadata file.

Phase 2: Minting Process

  1. Execution: After initialization, begin minting with the mint-dft command.
  2. Command Format: Run npm run cli mint-dft <ticker> with optional flags to adjust fees.
  3. Start Point: Minting commences at the predefined block height, allowing participants to claim tokens.

This method ensures a fair and open process, encouraging widespread distribution.

Atomicals vs. Ordinals: Key Differences in Bitcoin Token Protocols

While both Atomicals and Ordinals expand Bitcoin’s functionality, they serve different purposes and use distinct technical approaches.

Ordinals Protocol

Ordinals focus on non-fungible tokens (NFTs) by inscribing data directly onto individual satoshis. This allows for the creation of unique digital artifacts, such as images, texts, or videos, stored permanently on-chain. Key features include:

Ordinals enhance Bitcoin’s cultural value but do not support fungible tokens like currencies or utility tokens.

Atomicals Protocol

Atomicals enable both fungible and non-fungible assets through the ARC-20 and ARC-721 standards. Key features include:

Atomicals provide a versatile framework for tokenization, making Bitcoin a multi-asset network.
