What it is
Ordinals is a numbering scheme and protocol that assigns a unique identifier to each individual satoshi, the smallest unit of Bitcoin. This protocol allows users to "inscribe" arbitrary data, such as images, videos, or text, directly onto these numbered satoshis, effectively creating Bitcoin-native digital artifacts similar to non-fungible tokens (NFTs). Each inscribed satoshi is unique and its history can be tracked on the blockchain.
Ordinals generated significant news and debate since their introduction in early 2023, often discussed in relation to Bitcoin's evolving utility and network fees. Reports cover the surging transaction fees and block space demand attributed to Ordinal inscriptions. Readers need to understand that Ordinals leverage Bitcoin's existing security and immutability, but their popularity can lead to network congestion and higher transaction costs for regular Bitcoin users, impacting market dynamics.
Why it matters
Ordinals represent a new use case for Bitcoin, allowing for unique digital assets directly on the blockchain. They can impact network fees and bring new attention to Bitcoin.
