Bitcoin STAMPS (also called SRC-20 tokens) are a new class of Bitcoin-native NFTs that store tiny images directly in spendable transaction outputs on the Bitcoin blockchain. Because the image data is encoded as base64 and split across transaction outputs, STAMPS are designed to be immutable and resistant to pruning, distinguishing them from other inscription methods that rely on witnesses or external databases. Technical constraints limit STAMPS to very small graphics (24×24 pixels) and only a few file types (PNG, GIF, SVG), which reduces storage overhead but also constrains creative possibilities. The protocol is still early-stage: initial implementations used Counterparty broadcasts, while updated SRC-20 encoding writes directly to Bitcoin transactions, and ecosystem integration with wallets and marketplaces is ongoing. Reception is mixed—some criticize the network cost and limited utility, while others view STAMPS as a way to spur Bitcoin infrastructure and collector interest.

This article from The Bitcoin Manual explains the emergence of SRC-20 tokens and the STAMPS protocol as Bitcoin-native experiments for tokenization and lightweight NFTs. It describes how STAMPS (Secure Tradeable Art Maintained Securely) embed data into the Bitcoin UTXO set using either OP_RETURN for very small payloads or a fake multi-signature construction for larger files, leveraging ideas from the Counterparty project. The piece compares STAMPS and SRC-20 tokens with Ordinals and Inscriptions, highlighting trade-offs such as greater permanence in the UTXO set, higher resource usage and costs, and non-interoperability with Ordinals. It reviews likely use cases (fractionalized pixel art NFTs), tooling and integration efforts, and offers a skeptical perspective on speculative adoption and potential network impacts.

SRC-20 tokens are a Bitcoin-based token standard that enables embedding data directly into Bitcoin transactions using the Bitcoin Stamps protocol. They allow creators to mint fungible (and in some workflows non-fungible) digital assets by storing image and metadata in UTXOs in Base64 format, which makes the data immutable and non-prunable. SRC-20 tokens support common image formats such as JPG, PNG, GIF and SVG, but practical implementations impose a strict image size limitation (commonly 24x24 pixels) to keep on-chain storage feasible. The standard has seen rapid adoption with hundreds of thousands of tokens minted and a market capitalization that has grown into the tens of millions. SRC-20 expands Bitcoin’s utility beyond simple payments, offering secure collectible, NFT and token use cases while integrating transaction fees and minting activity into the existing Bitcoin economy.

SRC-20 (Bitcoin Stamps) is a token standard introduced in March 2023 that enables the creation of immutable, image-based tokens on the Bitcoin network by embedding base64-encoded image data into the UTXO set via the Counterparty protocol. Designed by Mike In Space and built on the Secure Tradeable Art Maintained Securely (STAMPS) concept, SRC-20 seeks to address perceived weaknesses of earlier ordinal-based standards like BRC-20 by prioritizing permanence and UTXO-based indexing. SRC-20 stamps typically store small PNG/GIF/WebP/JPG files (commonly suggested as 24x24, 8-color PNG/GIF) encoded in the transaction’s description field, and are mintable via tools such as Stamp Wallet and tradable on marketplaces like OpenStamp. While gaining rapid adoption (examples include tokens like PEPE, STAMP, and KEVIN), SRC-20 tokens remain experimental, volatile, and require careful handling of wallet compatibility and on-chain costs.

Bitcoin Stamps, often referred to as SRC-20 tokens, are a novel form of digital collectible recorded directly on the Bitcoin blockchain. Unlike some other token standards that place data in witness fields, SRC-20 uses spendable transaction outputs (UTXOs) to embed small image data and metadata, giving these tokens enhanced permanence and resistance to pruning. Creation of a Stamp follows strict rules — images must be JPG/GIF/PNG/SVG and limited to 24×24 pixels, each Stamp needs a unique numerical identifier, and encoded data is uploaded to a centralized repository such as stampchain.io with transactions flagged via a "stamp:base64" descriptor. SRC-20 tokens benefit from Bitcoin’s security and immutability but face trade-offs including higher transaction fees, limited scalability, nascent tooling, and regulatory uncertainty. Examples of notable SRC-20 tokens include PEPE SRC, KEVIN, STAMP, and SATO, illustrating the format’s growing creative and cultural uptake within the Bitcoin ecosystem.
