Parent-Child Inscriptions Explained
Learn how parent-child inscriptions work — the system for creating on-chain collections, hierarchies, and linked digital artifacts on Bitcoin.
1Simple Explanation
A parent-child inscription is a way to link inscriptions together on Bitcoin. A parent inscription is the main item (like a collection), and child inscriptions belong to it (like items in that collection). It's similar to how a folder contains files.
2Why It Matters
Parent-child relationships enable:
- •Collections — group related inscriptions under one parent
- •Provenance — prove that a child inscription was created by the parent's owner
- •Hierarchies — build complex structures of related content
- •Game assets — link character items, levels, and metadata to a parent game
This is how most major Ordinals collections organize their items on-chain.
3How It Works
- •Create a parent inscription — this is your collection or root item
- •Create child inscriptions — when inscribing, reference the parent's inscription ID
- •The Bitcoin transaction proving the relationship is recorded on-chain
- •Explorers and marketplaces can then display the parent-child hierarchy
The parent must be in your wallet when you create child inscriptions, proving ownership and authorization.
4Real-World Example
Imagine you're creating a pixel art collection called "CryptoCritters":
- •Parent: Inscribe the collection metadata (name, description, image)
- •Children: Inscribe each individual CryptoCritter as a child of the parent
- •Each child references the parent inscription ID
- •Marketplaces automatically group all children under the CryptoCritters collection
This creates a verifiable on-chain collection structure.
5Creating Parent-Child Inscriptions
To create parent-child inscriptions:
- •Inscribe the parent using any standard inscription method
- •Note the parent's inscription ID
- •When inscribing children, include a parent reference in the inscription envelope
- •The child transaction must spend the UTXO containing the parent inscription
- •This proves you own the parent and authorizes the child relationship
Several inscription services support parent-child creation. You can also use our Inscription Creator tool to build the HTML content for your parent inscription.
