About Bitcoin Ordinals
Ordinals enable inscribing arbitrary data (images, text, HTML, code) directly onto individual satoshis on Bitcoin. Each inscription is immutable, permanent, and fully on-chain.
These tools help you create, explore, and optimize ordinals inscriptions — from metadata and recursive references to parent-child provenance and sat rarity tracking.
