Bitcoin Ordinals

Bitcoin Ordinals are a way to inscribe data directly onto individual satoshis, the smallest units of Bitcoin, creating unique digital artifacts that resemble NFTs but do not use smart contracts. The system relies on the Taproot upgrade that expanded how much data a transaction can carry, which opened the door to storing images and files on-chain. An ordinal links a piece of data to a specific satoshi by assigning that satoshi a sequential rank based on when it was mined, and that rank can create collectible rarity. Think of each inscribed satoshi as a marked coin that carries a story; the coin itself has base monetary value and the inscription can add artistic or historical value. Because ordinals live inside satoshis, they inherit Bitcoin’s UTXO model, and that has practical consequences for everyday use. Each UTXO is spent whole in a transaction, so moving normal bitcoin from a wallet that also holds ordinals can accidentally transfer an inscribed satoshi unless accounts and addresses are segregated. For that reason you should use Taproot-compatible wallets and maintain a dedicated address or account for ordinals separate from your main holdings. Software wallets are convenient and support inscription management, but they expose private keys to the internet and increase risk. Hardware wallets keep keys offline and act like a secure vault for signing transactions, so use them whenever you handle valuable inscriptions. You can obtain ordinals through specialized marketplaces or by peer-to-peer trades, but OTC deals carry higher risk and require strong operational security. To create an ordinal you can run a full Bitcoin node and inscribe directly, which gives maximum control, or you can use trusted inscription services that handle node operations for you and submit the transaction. The ecosystem quickly spawned experiments that include single-piece artworks, generative series, and token-like constructs built on top of inscription mechanics, and those experiments show both the creative power and the fragility of a nascent market. Treat inscriptions as fragile artifacts in a hostile field. Label addresses, generate fresh receiving addresses for each incoming inscription, and double-check UTXO details before signing any transaction. The technology is elegant and robust at the protocol level, but new markets and tooling bring smart risks. Knowledge, discipline, and offline key custody are your best defenses as this class of on-chain collectibles matures.
