What Are Bitcoin SRC-20 Token Standard?

Cryptocurrency is constantly developing, and SRC-20 tokens are the latest buzz in the Bitcoin industry. These tokens are similar to the special elements that give Bitcoin new abilities, particularly Bitcoin Stamps.

Is 2023 heralding a significant focus on token standards within the cryptocurrency sphere? A prominent occurrence is the introduction of the SRC-20 standard within the Bitcoin blockchain, drawing parallels with Ethereum’s renowned ERC-20. 

This adoption of SRC-20 is perceived by many as a pioneering step, infusing a fresh facet into digital art and tokens on the Bitcoin network, and amalgamating innovation with established practices. Similar to the well-known token standard BRC-20, this development prompts considerations about its implications for the future of Bitcoin and digital assets.

Impact of SRC-20 Token Standard on Bitcoin

The SRC-20 token standard was developed specifically to generate and oversee tokens, notably Bitcoin Stamps, within Bitcoin’s blockchain. SRC-20 facilitates the incorporation of information into Bitcoin transactions, much like the BRC-20 standard, albeit with distinct methods of embedding data.

Bitcoin Stamps, also recognized as SRC-20 tokens, essentially represent digital collectibles housed on Bitcoin’s blockchain. Initially, they utilized the Counterparty protocol to convert images into encoded files for dissemination across the Bitcoin network.

Benefits of SRC-20 Token Standard

Distinguishing itself through its utilization of unspent transaction outputs (UTXOs) rather than witness data for storage, Bitcoin Stamps stand out. UTXOs resemble the leftover balance from a Bitcoin transaction.

The emergence of SRC-20 tokens has significantly broadened Bitcoin’s functionality, shifting it from a mere store of value to a more versatile platform. Nevertheless, this evolution has ignited debates, with some perceiving it as a departure from Bitcoin’s original intent as conceptualized by Satoshi Nakamoto.

SRC-20 tokens need to adhere to specific criteria for their proper creation. They can encode only specific image file formats and are restricted to a maximum size of 24×24 pixels. Each Bitcoin Stamp necessitates a unique identifier and is formed by appending “stamp:base64” within a new transaction.

Despite concerns regarding their impact on blockchain size and transaction fees, SRC-20 tokens are gaining popularity. They are seen as a driving force behind the enthusiasm for non-fungible tokens (NFTs) within the realm of Bitcoin and are deemed more secure and immutable compared to other standards due to their non-prunable nature. Noteworthy SRC-20 tokens encompass PEPE SRC, KEVIN, STAMP, and SATO.

What Are Bitcoin Stamps?

Bitcoin Stamps, identified as SRC-20 tokens, represent a variant of NFTs integrated with the Bitcoin blockchain. They signify an expansion of the blockchain’s role beyond just being a decentralized financial system.

These tokens are integral to a nascent framework known as Secure Tradeable Art Maintained Securely (STAMPS), which facilitates the inclusion of various data, such as digital artworks, directly within Bitcoin transactions. This advancement broadens the scope of the Bitcoin blockchain, evolving it from merely a repository of value to a platform capable of supporting diverse applications.

SRC-20 tokens draw inspiration from both Ordinal Inscriptions and the Counterparty protocol. Ordinal Inscriptions, introduced in January 2023, enable the inscription of digital content onto the Bitcoin blockchain. Meanwhile, Counterparty, a peer-to-peer platform built upon Bitcoin, was employed to issue NFTs by burning Bitcoin.

The distinctive feature of SRC-20 tokens lies in their method of embedding data into the blockchain. They encode image data, in formats like GIF, PNG, or SVG, into a base64 string, integrating it into the description key of the transaction. This approach of storing data directly in transaction outputs renders SRC-20 tokens immutable and permanently affixed to the blockchain, making them impossible to remove.

The technology underpinning SRC-20 tokens has been likened to ERC-1155 tokens on Ethereum, known for their capability to manage both fungible and non-fungible tokens within a single transaction. 

However, SRC-20 tokens possess unique attributes that set them apart. Due to their high expense and the necessity for block space, they can only accommodate small images (24×24 pixels). This limitation contrasts with Ordinal inscriptions, which can handle larger data sizes.

Comparison Between Bitcoin Stamps and Bitcoin Ordinals

Bitcoin Stamps and Bitcoin Ordinals present two distinctive methods for embedding information within the blockchain, each offering unique traits and functionalities.

Difference between Bitcoin Stamps and Bitcoin Ordinals

Bitcoin Stamps

▪️ Technical Integration: Bitcoin Stamps are directly incorporated into the Unspent Transaction Output (UTXO) set of the Bitcoin blockchain, ensuring the data becomes an enduring and immutable aspect of the blockchain ledger.

▪️ Data Permanence and Security: Their unalterable nature ensures data permanence, with Bitcoin Stamps persisting indefinitely on the blockchain, thereby bolstering security and establishing trust.

▪️ Impact on Blockchain Efficiency: Engineered to occupy minimal space, Bitcoin Stamps have minimal effect on the overall efficiency and scalability of the Bitcoin network.
