While this expansion has sparked debates within the community about alignment with Satoshi Nakamoto's original vision, SRC-20 tokens continue to reshape the landscape of digital assets by combining cutting-edge technology with artistic expression, enabling the creation of immutable digital assets through distinctive data embedding techniques.

What is SRC-20 and its impact on Bitcoin?

The SRC-20 token standard represents a specialized framework designed for creating and managing tokens on Bitcoin's blockchain, with particular emphasis on Bitcoin Stamps. This standard enables the embedding of data directly into Bitcoin transactions, sharing similarities with the BRC-20 standard while employing distinct data embedding methodologies. Bitcoin Stamps, the primary implementation of SRC-20 tokens, function as digital collectibles permanently stored on Bitcoin's blockchain. The initial implementation leveraged the Counterparty protocol to transform images into encoded files that could be broadcast to the Bitcoin network.

What distinguishes Bitcoin Stamps from other token standards is their unique storage methodology. Rather than utilizing witness data, these SRC-20 tokens employ unspent transaction outputs (UTXOs), which represent the residual balance from Bitcoin transactions. This approach ensures greater permanence and immutability of the stored data. The rise of SRC-20 tokens has significantly expanded Bitcoin's functionality, evolving the network from a simple value store into a versatile platform capable of supporting diverse applications. However, this evolution has generated considerable debate within the community, with some members expressing concerns that these developments deviate from Bitcoin's original purpose as conceived by Satoshi Nakamoto.

The creation of SRC-20 tokens must adhere to specific technical criteria. These SRC-20 tokens can only encode particular image file types, including JPG, GIF, PNG, and SVG formats, and are restricted to a maximum resolution of 24×24 pixels. Each Bitcoin Stamp must possess a unique numerical identifier and is created by incorporating "stamp:base64" encoding within a new transaction. Despite ongoing concerns regarding their impact on blockchain size and transaction fees, SRC-20 tokens have gained substantial popularity. They are increasingly viewed as a catalyst for NFT enthusiasm within the Bitcoin ecosystem and are considered more secure and immutable than alternative standards due to their non-prunable nature. Notable examples of SRC-20 tokens include PEPE SRC, KEVIN, STAMP, and SATO.

What are Bitcoin Stamps?

Bitcoin Stamps, formally known as SRC-20 tokens, represent a novel category of non-fungible tokens (NFTs) constructed on the Bitcoin blockchain. This development signifies a meaningful extension of the blockchain's capabilities beyond its original function as a decentralized financial system. These SRC-20 tokens operate within an emerging protocol called Secure Tradeable Art Maintained Securely (STAMPS), which facilitates the direct embedding of data, including digital artwork, into Bitcoin transactions. This technological advancement has substantially expanded the Bitcoin blockchain's functionality, transforming it from a simple store of value into a platform capable of supporting a broader spectrum of applications.

The conceptual foundation of SRC-20 tokens draws inspiration from both Ordinal Inscriptions and the Counterparty protocol. Ordinal Inscriptions, introduced in early 2023, pioneered the ability to inscribe digital content directly onto the Bitcoin blockchain. Meanwhile, the Counterparty protocol, a peer-to-peer platform built on Bitcoin, had previously been utilized for issuing NFTs through a process of burning Bitcoin. SRC-20 tokens distinguish themselves through their unique data embedding methodology. They encode image data from formats such as GIF, PNG, or SVG into a base64 string, which is then incorporated into the transaction's description key. This approach to storing data directly in transaction outputs renders SRC-20 tokens immutable and permanently integrated into the blockchain, as they cannot be pruned or removed.

The underlying technology of SRC-20 tokens has drawn comparisons to Ethereum's ERC-1155 token standard, which is recognized for its capability to handle both fungible and non-fungible tokens within a single transaction. However, SRC-20 tokens possess specific characteristics that differentiate them from other standards. Due to the substantial costs and block space requirements associated with Bitcoin transactions, SRC-20 tokens can only accommodate small images with a maximum resolution of 24×24 pixels. This limitation contrasts notably with Ordinal inscriptions, which can support larger data sizes and more complex content.

Bitcoin Stamps vs Bitcoin Ordinals

Bitcoin Stamps and Bitcoin Ordinals represent two innovative yet fundamentally different approaches to embedding data into the Bitcoin blockchain, each characterized by distinct technical implementations and functional capabilities that serve different use cases within the ecosystem. Understanding the differences between these standards, particularly the unique advantages of SRC-20 tokens, is crucial for developers and users.

Bitcoin Stamps, utilizing the SRC-20 standard, are integrated directly into the Bitcoin blockchain's Unspent Transaction Output (UTXO) set, ensuring that embedded data becomes a permanent and immutable component of the blockchain. This unchangeable nature guarantees perpetual data permanence, meaning that once a Bitcoin Stamp is created using the SRC-20 standard, it remains on the blockchain indefinitely, significantly enhancing security and trust. The design of Bitcoin Stamps emphasizes minimal space occupation, resulting in negligible impact on the overall efficiency and scalability of the Bitcoin network. This makes SRC-20 tokens particularly suitable for applications requiring long-term data integrity, such as legal documents, certificates, historical records, and other scenarios where permanent storage is essential. Furthermore, their permanent nature makes Bitcoin Stamps highly reliable for compliance with legal and regulatory requirements, as the data cannot be altered or removed over time.

In contrast, Bitcoin Ordinals employ a different technical approach by inscribing data onto individual satoshis. While this method represents an innovative way to tag and track satoshis, it depends on the discretion of network nodes, which may choose to prune this data for performance optimization purposes. This potential for data pruning introduces concerns about long-term security and reliability, as there is no guarantee that the inscribed data will remain accessible indefinitely. The process of inscribing data on individual satoshis can contribute to blockchain bloat, potentially slowing down network performance and impacting transaction processing times, which raises important scalability considerations. While Ordinals offer unique functionality for tracking and identifying specific satoshis, their potential impermanence makes them less suitable for applications where data longevity and guaranteed preservation are critical requirements, areas where SRC-20 tokens excel.

What are the technical specs of SRC-20?

The technical specifications of SRC-20 tokens encompass several critical components that define their functionality and implementation on the Bitcoin blockchain.

This architectural shift enables direct data embedding into Bitcoin transactions, providing a unique approach that distinguishes SRC-20 from other standards such as BRC-20. The data storage method constitutes one of the most crucial features of SRC-20 tokens, utilizing unspent transaction outputs (UTXOs) for data storage. This methodology ensures that data, including images and text, is permanently stored on the blockchain in a manner that makes it impossible to prune or remove.

Regarding token characteristics, SRC-20 tokens can encode several specific file types, including JPG, GIF, PNG, and SVG formats. However, encoded files are subject to a strict size limitation, restricted to a maximum resolution of 24×24 pixels. Each Bitcoin Stamp must possess a unique numerical identifier to ensure proper tracking and verification within the system. The minting process for SRC-20 tokens involves several technical steps: first, an image is converted to text format, then encoded as a Base64 file, and finally, the prefix "Stamp:" is appended before the text. This encoded file is subsequently broadcasted to the Bitcoin network for validation, where it is compiled back into the original image format.

The transaction and decoding process for SRC-20 tokens involves encoding a "STAMP:base64" string within the description key of a transaction. These SRC-20 tokens can be decoded directly from the original Bitcoin transaction, ensuring transparency and verifiability. When comparing SRC-20 tokens with other standards, they share similarities with Ethereum's ERC-1155 token standard, as both facilitate the efficient transfer of fungible and non-fungible tokens. However, SRC-20 is specifically engineered for the Bitcoin blockchain and possesses unique characteristics tailored to Bitcoin's architecture.

Resource usage and associated costs represent important considerations for SRC-20 token implementation.
