SRC-20 Tokens: A New Breed of Digital Assets on the Bitcoin Blockchain

SRC-20 tokens represent a new breed of digital assets on the Bitcoin blockchain. They allow users to embed data directly into transactions

SRC-20 tokens, often referred to as SRC 20 or SRC20 tokens, are a new type of digital asset on the Bitcoin blockchain that enables the direct embedding of data within transactions, ensuring immutability and permanence. They are distinct from other token standards in their use of the Bitcoin Stamps technology to store data in unspent transaction outputs (UTXOs).

Here are some key aspects of SRC-20 tokens:

They are fungible tokens that can store a variety of image types, including JPG, SVG, GIF, and PNG, though they're limited to 24x24 pixels in size.

With over 260,000 tokens minted and a market capitalization exceeding $100 million, SRC-20 tokens have gained significant traction.

They are designed to support various digital collectibles use cases within the broader Bitcoin ecosystem.

Bitcoin Stamps, embodied by the SRC20 stamp protocol, are a new method for embedding images directly onto the Bitcoin blockchain. This technology allows users to mint non-fungible tokens (NFTs) and expand the use cases of Bitcoin, in the sense that it allows incorporating unique digital images into the blockchain.

Each Stamp is identified by a unique transaction number and contains a valid image string in base64 format, a component that’s crucial for its legitimacy. This base64 encoding makes sure that the Stamp is safely encoded and easily recoverable from the transaction data.

When you create a Bitcoin Stamp, the metadata for the original image is securely stored in the UTXO, which prevents data pruning. This makes Stamps truly permanent digital artifacts.

Bitcoin Stamps mostly focus on artistic representation and collectibles, and are therefore distinguishable from other asset types. The technology offers users an engaging way to create, buy, and trade unique digital art within the Bitcoin ecosystem.

As opposed to Bitcoin Ordinals, which inscribe data on satoshis that can be pruned, Stamps embed metadata permanently in UTXOs. This difference in storage method leads to distinct use cases and levels of data reliability.

Here are some key distinctions to consider:

The data for SRC-20 tokens is stored by converting images to a Base64 format and decoding it within the description key of a Bitcoin transaction, which ensures permanent and immutable storage on the blockchain.

The process creates a unique, numerical identifier for each token, making them indivisible.

Once encoded, these tokens are broadcast to the Bitcoin network for validation. The use of UTXOs as the storage method sets SRC-20 tokens apart from other standards and makes the data non-prunable, allowing each token to be truly immutable and secure.

After they’re created, these tokens must meet specific criteria. Each stamp must be numerical and have a unique identifier.

As you delve deeper into the Bitcoin ecosystem, it becomes evident that SRC-20 tokens have notably broadened the use cases of this blockchain and made it more competitive with other decentralized platforms.

The SRC-20 token standard has expanded the capabilities of the Bitcoin blockchain. What used to be used purely for financial transactions has now gained new use cases. Four key impacts include:

To fully utilize the versatility of SRC-20 tokens, you begin by understanding the essential steps for creating and managing these innovative assets within the Bitcoin ecosystem.

Transaction fees for SRC-20 tokens are paid in Bitcoin, ensuring seamless integration within the ecosystem.

SRC-20 and BRC-20 tokens each have their own unique features that impact how data is embedded and managed within the Bitcoin ecosystem.

SRC-20 tokens leverage the Bitcoin Stamps protocol for immutable data storage on UTXOs. It's worth noting that the Stamp protocol has its own token, STAMP, which is used for trading, peer-to-peer (P2P) transactions, and memorial inscriptions on the Bitcoin blockchain.

BRC-20 tokens, on the other hand, utilize Bitcoin Ordinals for data that can be modified and potentially pruned. The Ordinal protocol’s native token is ORDI, and it fulfills a similar function as STAMP.

Here are the key differences between SRC-20 and BRC-20:
