This guide aims to introduce you to the world of Ordinals, explaining their significance and how they work.

Bitcoin Ordinals involve assigning numbers to Satoshis (sats), the smallest units of Bitcoin, to create unique Digital Artifacts directly on the blockchain. These inscriptions contain content such as text, images, or videos, stored in the witness portion of a Bitcoin transaction. With the 2021 Taproot upgrade, inscriptions of nearly 4 MBs in size are now possible, allowing for more complex creations.

Ordinals are numerical values assigned to Satoshis based on their order of mining and transfer. This tracking system facilitates the creation and transfer of individual sats, making it possible to generate unique digital assets, including NFTs (Non-Fungible Tokens), directly on the Bitcoin blockchain. The concept of Ordinal Theory proposes a methodology for identifying and tracking sats individually, even though they are not serialized at the protocol level. Instead, inscriptions provide stable identifiers for various Bitcoin applications.

The term "digital artifact" is sometimes used instead of "NFT" to make the concept more accessible to a broader audience. By associating the word "artifact" with historical or archaeological objects, the significance and value of sat inscriptions as unique digital creations become more apparent. Collectibles on Bitcoin are most commonly called Ordinals.

The Bitcoin Mempool serves as a temporary storage area for pending transactions in the Bitcoin network. When a transaction is initiated, it is broadcast across the network and picked up by a miner to be included in the next block. However, as blocks have limited space, some transactions must wait in the Mempool until they can be processed. The priority for inclusion in the next block is determined by the transaction fees offered by users, creating a queue for unconfirmed transactions.

To receive and store Bitcoin Ordinals, it's essential to utilize a separate address from your primary Bitcoin wallet. Bitcoin wallets like Magic Eden Wallet fully support Ordinals, offering a user-friendly interface for easy management.

When sending Digital Artifacts, ensure that you use addresses specifically set up to receive Ordinals. Standard Bitcoin addresses are not suitable for this purpose. Review this article for more information.
