Guide to Bitcoin inscriptions (Ordinals) — creating, minting, and managing content inscribed on the Bitcoin blockchain. Covers Ordinal theory, inscription types (text, images, HTML), BRC-20 tokens, recursive inscriptions, and marketplace integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bitcoin Inscription Guide
Bitcoin inscriptions (Ordinals) let you permanently embed content — text, images, HTML, code — directly on the Bitcoin blockchain. This guide covers the full lifecycle from creation to marketplace.
## What Are Inscriptions?
Inscriptions use the Ordinals protocol to embed arbitrary content into individual satoshis:
```
Bitcoin Transaction
│
└── Witness Data (SegWit)
│
└── Inscription Envelope
├── Content-Type: "text/plain"
└── Body: "Hello, Bitcoin!"
```
## Inscription Types
| Type | Content-Type | Max Size | Use Case |
|------|-------------|----------|---------|
| **Text** | text/plain | ~390KB | Messages, poems, data |
| **Image** | image/png, image/webp | ~390KB | Art, pfps, memes |
| **HTML** | text/html | ~390KB | Interactive content |
| **SVG** | image/svg+xml | ~390KB | Vector art |
| **JSON** | application/json | ~390KB | BRC-20 tokens, metadata |
| **JavaScript** | text/javascript | ~390KB | Recursive inscriptions |
| **Audio** | audio/wav | ~390KB | Music |
| **Video** | video/mp4 | ~390KB | Short clips |

How to install
mdr add nirholas/three.ws/bitcoin-inscription-guide@sha256:10bb96f57c6d3a62The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
