Bitcoin Stamps vs Ordinals: Why is this new protocol safer?

Core Points

Bitcoin Stamps is a new way to mint digital art on the Bitcoin blockchain, offering several key advantages over Ordinals: data immutability, flexible costs, and enhanced security.

What are Bitcoin Stamps?

In simple terms, it is a protocol that permanently engraves digital art on the Bitcoin blockchain. The way it works is as follows:

  1. Convert the artwork into a Base64 encoded string
  2. Add the prefix “STAMP:” in Bitcoin transactions
  3. Distribute data across multiple UTXOs through multi-signature transactions.
  4. Each Stamp is assigned a number, sorted by transaction time.

The benefits of doing this are: data is permanently stored on the chain and cannot be deleted or tampered with.

Two Protocol Standards

SRC-20: Based on the Counterparty open protocol, directly embed arbitrary data in the transaction output.

SRC-721: Optimized specifically for NFTs, supports layered image storage, and compresses file size using technologies like indexed palettes. An image starting at 24x24 pixels can be minted, with costs lower than single-layer images.

Why do people say Stamps are tougher than Ordinals?

Features Stamps Ordinals
Data Pruning ✓ Non-deletable (exists in UTXO) ✗ Can be pruned (witness data is modifiable)
Data Size Flexibly adjustable, supports layered compression Limited by block size, resolution is constrained
Signing Method Multi-signature framework, higher security Single-signature mode
Cost Adjustable with resolution, can be optimized Trading fees are relatively stable but lack flexibility

The most critical difference: The data of Ordinals can theoretically be deleted by nodes (data pruning), but Stamps exist in UTXO, and deleting them would equate to damaging the transaction output, which is not possible within the Bitcoin mechanism.

How to choose?

  • Want the highest security + file optimization? Choose Stamps
  • Want simplicity and speed + already have a mature ecosystem? Choose Ordinals

Both protocols are evolving, but the multi-signature + UTXO design of Stamps is indeed more robust in terms of tamper resistance.
