The Concept of Bitcoin Stamps

What are Bitcoin Stamps?

Bitcoin Stamps, or Bitcoin Secure Tradeable Art Maintained Securely (STAMPS), emerged as a trending innovation in the digital collectibles space around March-April of this year. As non-fungible tokens (NFTs) stored directly on Bitcoin's unspent transaction outputs (UTXOs), they offer a unique approach to permanence and immutability, distinguishing themselves within the Bitcoin ecosystem.

Historical Context and Origin

The development of Bitcoin Stamps can be traced back to the Counterparty protocol, an open-source messaging protocol launched in 2014. This protocol laid the foundation for standardized NFTs on the Bitcoin Blockchain, giving rise to collections like Spells of Genesis and Rare Pepes.

In 2017, an artist and developer called “Mike in Space!” began exploring Counterparty, eventually creating a Proof-of-Concept for a Name Service. This work laid the groundwork for the STAMPS protocol, with Kevin and Arwyn later coding a functional version based on Mike's concept.

The Bitcoin STAMP embeds base64-formatted image data onto the Bitcoin blockchain using transaction outputs. This method ensures the data's permanence and immutability, making it impossible to prune from a full node.

The Technology Behind Bitcoin Stamps

How Bitcoin Stamps Work?

Creating a Bitcoin Stamp involves converting an image into a special base64 format, which allows the image to be represented as a string of characters. This image string is added to the description of a Bitcoin transaction and sent to the Bitcoin network using the Counterparty protocol. Each Bitcoin Stamp is given a number based on when the transaction took place, organizing the Stamps in chronological order. Unlike other digital collectibles, Bitcoin Stamps are stored directly on the Bitcoin blockchain, specifically on unspent transaction outputs (UTXOs), ensuring that the images are securely and permanently recorded.

Protocols: SRC-20 and SRC-721

Bitcoin Stamps currently utilize two main protocols: SRC-20 and SRC-721:

• SRC-20: A groundbreaking token specification that revolutionizes counterparty assets. Inspired by the BRC-20 standard, SRC-20 tokens operate uniquely, eliminating the need to burn bitcoins or employ alternative cryptocurrencies. They facilitate seamless payment through BTC transactions, fostering an ecosystem that thrives around their usage.

• SRC-721: A specification focusing on enabling higher-resolution composable NFTs at a more affordable cost. It allows for the storage of collection art as layers using the STAMPS protocol, reducing file size through techniques such as indexed color palettes for each layer. The specification outlines various transaction types, including deployment, reveal, minting for collections and individual items, and transfer/use of SRC-721 tokens.

Minting, Buying, and Selling Bitcoin Stamp Art

Minting stamp art has become more accessible with platforms such as RareStamp, OpenStamp, StampChain, and Assetic. These platforms provide artists and creators the opportunity to showcase unique stamp designs as NFTs on the blockchain. The process of buying and selling Bitcoin Stamp art involves creating a dispenser using FreeWallet functionality, with platforms like xchain.io facilitating visibility.

Trading and Deploying SRC-20 Tokens

Trading SRC-20 tokens is currently possible on marketplaces like The Stamp Wallet and Openstamp. The Stamp Wallet simplifies the process of deploying SRC-20 tokens on the Stampchain, while Rarestamp offers a user-friendly platform for deploying custom SRC-20 tokens.

Bitcoin Stamps and Ordinals Faceoff

The table below illustrates the key differences between Bitcoin Stamps and Ordinals, emphasizing their unique characteristics in terms of immutability, size, file type, integration, cost, and flexibility. While both innovations contribute to the digital collectibles space on the Bitcoin blockchain, they offer distinct advantages and limitations that cater to different needs and preferences.

The Controversy around Bitcoin Stamps

Immutability and UTXO Set Bloating

The controversy around Bitcoin Stamps touches on various areas, including discussions around immutability and bloating the UTXO set. When comparing Bitcoin Stamps to Ordinals, a heated debate emerged about which was more or less prunable. Bitcoin Stamps are less prunable because image data is stored in Bitcoin’s UTXOs instead of its witness data. In crypto lingo, a witness refers to a signature that attests to the authenticity of something. In the context of a Bitcoin transaction, the witness is the contents of the signature scripts since they prove the transaction's authentication.

The initial discussion around the UTXO set bloat largely revolved around the uncertainty of increasing hardware requirements (e.g., RAM) for users running a Bitcoin node.

Block Space Utilization

In addition to the technical debates, there has been disagreement within the Bitcoin community about using block space for the purpose of digital artwork. The ongoing debate around the size of blocks on the Bitcoin blockchain and how an increase in transactions settling on-chain would affect the network has been exacerbated by the emergence of Bitcoin Stamps.

Some community members have proposed increasing the block size, but many argue that it would make the network more vulnerable and raise the cost to miners due to increased data storage requirements.

The Industry’s Reaction to Bitcoin STAMPS

The reception to Bitcoin Stamps has been mixed. From a Bitcoin maximalist perspective, they are viewed as another “built-on-Bitcoin” project that could congest the network. The limited image size and perceived lack of utility have fueled skepticism.

On the other hand, Bitcoin Stamps are generating interest in the infrastructure around the Bitcoin network, impacting adoption, and potentially influencing positive price movements for Bitcoin.

Implications and Perspectives

The emergence of Bitcoin Stamps has sparked both excitement and controversy within the cryptocurrency community. The debates around immutability, UTXO set bloating, and block space utilization reflect broader discussions about the direction and priorities of the Bitcoin network. While some see Bitcoin Stamps as a promising innovation, others express concerns about their long-term impact and utility. The ongoing dialogue around Bitcoin Stamps underscores the dynamic and evolving nature of the blockchain and digital asset space.

Conclusion: Embracing Innovation and Navigating Challenges

The emergence of Bitcoin Stamps and the innovations surrounding them represents a significant milestone in the ongoing evolution of the Bitcoin ecosystem. From the early days of the Counterparty protocol to the latest developments in SRC-20 and SRC-721 tokens, the journey of Bitcoin Stamps encapsulates the creativity, experimentation, and ambition that characterize the blockchain and digital asset space.

Reflecting on the Past and Present

The history of Bitcoin Stamps, dating back to 2014 with the launch of the Counterparty protocol, showcases the relentless pursuit of new ways to utilize the Bitcoin blockchain. The recent trend since March-April this year, culminating in the current popularity of Bitcoin Stamps, illustrates the community's appetite for innovation and exploration.

Bridging Technology and Art

By enabling the minting, buying, selling, and trading of unique digital assets, Bitcoin Stamps have bridged the worlds of technology and art. Platforms like RareStamp, OpenStamp, and StampChain have democratized access to digital art, allowing artists and collectors to engage with the blockchain in novel ways.

Looking to the Future

As the Bitcoin Stamps phenomenon continues to unfold, it offers valuable insights into the potential and limitations of building on Bitcoin. The flexibility, security, and permanence of Bitcoin Stamps, coupled with the ongoing efforts to integrate them into marketplaces and wallets, hint at a promising future.

The enthusiasm around Bitcoin Stamps is a testament to the vibrant and dynamic nature of the Bitcoin community. It's a reminder that even a well-established technology like Bitcoin continues to inspire new ideas, challenge conventions, and drive the industry forward.

Whether viewed as a groundbreaking innovation or a contentious experiment, Bitcoin Stamps have undeniably left an imprint on the landscape of digital collectibles. They invite us to reflect on what's possible, engage with technology creatively, and navigate the ever-changing terrain of the blockchain world with curiosity and critical thinking.
