Move from creation to inscription seamlessly — optimized for desktop and mobile.
Index blocks, collections, and inscription types for fast retrieval and discovery.
Understand parcels, land structure, and how Bitmap indexing works.
Explore real-time indexed data for blocks, parcels, and deployments.
Coordinate trustless actions and extend Ordinals functionality beyond static inscriptions.
Bitcoin Ordinals is a protocol for inscribing data — images, text, video, code — directly onto individual satoshis (the smallest unit of Bitcoin). Each inscription becomes a permanent, immutable digital artifact stored entirely on the Bitcoin blockchain.
Unlike NFTs on other blockchains that often point to external servers, Ordinals inscriptions are fully on-chain. The data lives inside Bitcoin transactions, secured by the most battle-tested blockchain network in the world.
Open the full guideLearn the Bitmap model, understand how block-based land and child inscriptions fit together, and then open the live Bitmap420 explorer.
Open Bitmap guideAsk for a block range, inscription type, or collection to be indexed and added to the open BitmapIndexer workflow.
Open index request formAdd comments, report weak spots, suggest tool improvements, request new guides, or point out broken flows. This gives 0rdinals a visible feedback loop that people and search engines can both understand.
Open community feedbackClear keyword coverage helps search visibility, but real engagement helps even more. Public-facing feedback, feature requests, and guide improvements give the app fresher language around Bitcoin Ordinals, inscriptions, tools, and indexing.
The community page is built to collect comments, tool ideas, bug reports, and content corrections in one place so the app can keep improving in public-facing ways.
0rdinals can expose recursive application data as a virtual API. A recursive inscription can install a fetch shim, call /r/gallery/<inscription-id>, and receive JSON from your domain. This helps developers build recursive apps and also gives search engines and AI systems a clear endpoint to reference.

</script>0rdinals is an all-in-one Bitcoin Ordinals app focused on viewing live inscriptions, learning Ordinal theory, creating inscription-ready assets, handing off to Oodinals for inscription, indexing Bitmap plus BRC-420 data, and exposing gallery-ready recursive APIs.
The service also exposes same-domain content and recursive endpoints, including virtual APIs such as gallery data, so recursive applications can fetch JSON and media from 0rdinals routes instead of relying on multiple external domains.
This plain-language content is intentional: it helps human visitors, search engines, and AI systems understand exactly what the product does and which route to use for each task.

A complete beginner-friendly guide to Bitcoin Ordinals — what they are, how they work, and why they matter for the future of Bitcoin.
Step-by-step guide to creating your first Bitcoin Ordinals inscription — from preparing your file to broadcasting the transaction.
Understand the rarity system in Ordinal Theory — from common sats to the mythic first satoshi ever mined.
Learn how parent-child inscriptions work — the system for creating on-chain collections, hierarchies, and linked digital artifacts on Bitcoin.
Learn how to minimize file sizes for cheaper inscriptions — compression techniques, format selection, and tools to reduce fees.
Understand recursive inscriptions — how inscriptions can reference and compose other inscriptions to build complex on-chain applications.
Optimize files, create pixel art, build HTML inscriptions, and compress 3D models — all designed to help you create better inscriptions at lower cost.
Compress and decompress text or files using Gzip, Deflate, Deflate-Raw, or Brotli with real-time size comparison.
Compress images to WebP, JPEG, or PNG with quality controls and Squoosh-style split comparison.
Compress 3D models (GLB, glTF, STL, OBJ) with Google Draco — full quantization controls, encoding options, and split-screen comparison.
Build pixel art and sprite animations, export PNG sprite sheets, and generate voxel-style STL files for 3D printing.
Multi-page visual builder for on-chain HTML inscriptions. Design pages, add navigation links between pages, embed on-chain assets, and export multi-page inscription packages.
Load inscription-based 3D avatars, extract or paint skin textures with UV guide overlay, and export skin PNGs with metadata.
Inscriptions embed data in Bitcoin transaction witness fields (SegWit/Taproot). The data is assigned to a specific numbered satoshi and becomes permanent once the transaction is mined.
Ordinal Theory is a numbering scheme that assigns a unique sequential number to every satoshi ever mined, based on the order they were created. This allows individual satoshis to be tracked and collected.
Yes. Once inscribed on Bitcoin, the data is immutable and permanent. It becomes part of the blockchain's transaction history and cannot be deleted or modified.
Optimize your files to be as small as possible. Use WebP instead of PNG, compress text with Brotli, minify HTML/CSS/JS, and use our optimization tools to minimize byte count.
