Ordinals
What Are Ordinals?
Ordinals are a protocol that allows individual satoshis (the smallest units of BTC) to be uniquely identified and inscribed with arbitrary data, such as images, text, or code — enabling NFT-like assets natively on Bitcoin.
Developed by Casey Rodarmor and launched in early 2023, Ordinals use Taproot and SegWit to embed data directly into Bitcoin transactions without changing consensus rules or requiring new tokens.
🔧 How It Works
Each satoshi is assigned a unique ordinal number based on its position in the blockchain.
An inscription attaches data to a specific satoshi using witness data in a Taproot transaction.
The inscribed sat remains part of a UTXO, and can be transferred like any other Bitcoin output.
💡 Key Features
100% on-chain — no external storage or tokens
Immutable — data is stored forever on Bitcoin
Tokenless — no smart contracts, no ERC/BRC standards
UTXO-native — inscriptions live inside Bitcoin’s core structure
📦 What Can Be Inscribed?
Images (PNG, JPEG, SVG, WebP)
Text (Markdown, JSON, etc.)
HTML, JavaScript
Any arbitrary data (up to ~4 MB)
Ordinals turn Bitcoin into a canvas for digital artifacts — fully decentralized, permanent, and secured by the Bitcoin network itself.
