Bitcoin STAMPS are a relatively new innovation in the blockchain space, allowing users to embed non-fungible tokens (NFTs) directly onto the Bitcoin blockchain. Unlike other NFTs that often reside on blockchain networks like Ethereum, Bitcoin STAMPS leverage the Bitcoin blockchain's immutability and security to ensure the permanence of digital art and other media.

History of Bitcoin STAMPS

Bitcoin STAMPS were conceptualized as an enhancement to the Bitcoin Ordinals protocol, aiming to provide a more robust solution for NFT permanence on Bitcoin. The idea emerged from the need to store NFTs directly on the Bitcoin blockchain rather than relying on off-chain storage, which can be more vulnerable to data loss and tampering.

Bitcoin STAMPS Protocol

The Bitcoin STAMPS (Secure Transmission and Management of Protocols & Services) protocol is designed to facilitate the creation, transfer, and verification of Bitcoin STAMPS. This protocol includes standards for encoding data, ensuring that the NFTs can be easily read and verified by anyone running a Bitcoin node.

How Bitcoin STAMPS Work

Bitcoin STAMPS embed image data directly onto the Bitcoin blockchain using base64 formatting, allowing images to be represented in a text format. This data is included in Bitcoin transactions via the OP_RETURN field, with larger images split across multiple transactions. Once recorded, the image data is permanent and tamper-proof, leveraging Bitcoin's security and decentralization. 

This method is useful for preserving digital art and verifying document integrity, though it can be costly and increase blockchain size. Despite these challenges, Bitcoin STAMPS ensure that important visual data remains immutable and publicly verifiable. This innovative approach highlights the versatility of the Bitcoin blockchain beyond simple financial transactions.

Example Use Cases for Bitcoin STAMPS

Bitcoin STAMPS provide a secure and permanent way to embed and preserve image data on the blockchain. Here are the few examples:

1. Digital Art Preservation:

Artists can embed their digital artworks directly onto the Bitcoin blockchain, ensuring that the images are permanently preserved and can be publicly verified as original works.

2. Document Archiving:

Important documents and images can be embedded in the blockchain, providing a tamper-proof record that ensures the integrity and authenticity of the archived material.

3. Media Integrity:

Embedding media directly on the blockchain guarantees that the content has not been altered, offering a way to verify the integrity of critical visual data.

Bitcoin STAMPS Vs SRC-20 Vs SRC-721

Bitcoin STAMPS, SRC-20 tokens, and SRC-721 tokens represent distinct functionalities within the blockchain ecosystem. Bitcoin STAMPS focus on embedding data, such as images or document hashes, directly into the Bitcoin blockchain using techniques like base64 encoding in the OP_RETURN field of transactions. 

In contrast, SRC-20 tokens adhere to a fungible token standard on platforms like Ethereum, enabling tokenization of assets and facilitating transactions within decentralized applications (dApps). SRC-20 tokens are interchangeable and typically used for cryptocurrencies, loyalty points, or tokenized assets where uniformity in value and divisibility are essential. 

Meanwhile, SRC-721 tokens, a subset of non-fungible tokens (NFTs), are unique and indivisible digital assets. They are employed for representing ownership and provenance of distinct items such as digital art, virtual real estate, or in-game assets, providing a robust solution for managing scarce digital assets securely on the blockchain. 

Each token standard serves specific purposes within the blockchain ecosystem, catering to different use cases ranging from data embedding and fungible asset tokenization to unique asset representation and digital collectibles.

How to Mint Bitcoin STAMPS

Minting Bitcoin STAMPS involves creating a Bitcoin transaction that includes the desired data in the OP_RETURN field. This process ensures that the data is permanently embedded in the Bitcoin blockchain. Here are the steps involved:

1. Prepare the Data

  • Convert to Base64: The image or data you want to embed must be converted into base64 format. This encoding converts binary data into an ASCII string, making it suitable for inclusion in a Bitcoin transaction.

2. Split the Data

  • Chunking: Since the OP_RETURN field has an 80-byte limit, you need to split the base64-encoded data into chunks that fit within this limit. Each chunk will be embedded in a separate transaction.

3. Construct Transactions

  • Create Transactions: Construct Bitcoin transactions with OP_RETURN outputs containing the data chunks. Each transaction will carry a portion of the base64-encoded data.

4. Broadcast Transactions

  • Broadcast to Network: Once the transactions are constructed, broadcast them to the Bitcoin network. Miners will validate these transactions and include them in the blockchain.

5. Verify and Reconstruct

  • Data Retrieval: After the transactions are confirmed and included in the blockchain, you can retrieve and concatenate the data chunks to reconstruct the original base64 data and decode it back to its original form.

Bitcoin STAMP 0

Bitcoin STAMP 0 refers to the initial prototype or the first implementation of the Bitcoin STAMPS concept. It serves as a proof of concept, demonstrating the feasibility and practicality of embedding NFTs and other data directly onto the Bitcoin blockchain. This prototype showcases how Bitcoin STAMPS can be used for secure, tamper-proof data embedding, highlighting the potential for broader applications in digital art preservation, document archiving, and media integrity.

Key Considerations for Minting Bitcoin STAMPS

When minting Bitcoin STAMPS, there are several important factors to consider:

Permanence and Immutability

One of the key benefits of Bitcoin STAMPS is their permanence and immutability. Once data is embedded into the Bitcoin blockchain, it cannot be altered or removed, ensuring the long-term preservation of the NFT.

Transaction Costs

Embedding data in the Bitcoin blockchain incurs transaction costs, as each byte of data must be stored and maintained by the network. Users need to consider these costs when minting Bitcoin STAMPS, especially for larger files that require multiple transactions.

Bitcoin STAMPS vs. Bitcoin Ordinals

Bitcoin STAMPS is a method for embedding data into the Bitcoin blockchain using a unique technique. This method allows for the permanent storage of small pieces of data (such as text or images) within the blockchain. 

While Bitcoin Ordinals represent a system for creating and managing non-fungible tokens (NFTs) directly on the Bitcoin blockchain. This approach leverages the ordinal theory, which assigns a unique identifier to each individual satoshi (the smallest unit of Bitcoin).

Other key differences are:


Both Bitcoin STAMPS and Bitcoin Ordinals leverage the Bitcoin blockchain's immutability. However, Bitcoin STAMPS embed the entire NFT on-chain, while Ordinals may rely on off-chain storage for larger files, potentially impacting permanence.


Bitcoin STAMPS can be less efficient than Bitcoin Ordinals due to the need for multiple transactions to store large files. This can lead to higher transaction fees and longer processing times.


By storing data directly on the Bitcoin blockchain, Bitcoin STAMPS benefit from Bitcoin's robust security model. However, the increased use of OP_RETURN fields for data storage can raise concerns about blockchain bloat and its long-term implications.

How and Where to Buy Bitcoin STAMPS?

Bitcoin Stamp art can be bought and sold on platforms that support Bitcoin NFTs such as OpenStamp and STAMPScan. These platforms facilitate the transfer of ownership by creating new transactions that update the ownership metadata stored on the blockchain.


What is the purpose of STAMPS?

The purpose of Bitcoin STAMPS is to create immutable, on-chain NFTs that leverage Bitcoin's security and permanence. This ensures the long-term preservation of digital art and other unique assets.

How do I create a Bitcoin stamp?

To create a Bitcoin stamp, you encode your data into the base64 format and embed it within the OP_RETURN field of a Bitcoin transaction. This process includes dividing your data into manageable chunks, crafting the transactions accordingly, and then broadcasting them to the Bitcoin network.

How do you use crypto STAMPS?

Crypto STAMPS, like Bitcoin STAMPS, are used to represent and trade unique digital assets. They can be bought, sold, and transferred between users on the blockchain, with ownership and metadata stored immutably on the network.
