Bitcoin Inscriptions: Foundations and Beyond
Ningran Li, Minfeng Qi, Qin Wang, Shiping Chen
TL;DR
Bitcoin inscriptions extend the Bitcoin blockchain by embedding non-financial data directly into satoshis via the Ordinal protocol, creating on-chain digital artifacts that resemble NFTs. The authors provide a foundational technical treatment of the prerequisite technologies (SegWit, Schnorr, Taproot, Tapscript) and describe the two-phase commit/reveal mechanism that binds data to individual satoshis. They compare Bitcoin inscriptions with conventional NFTs on Ethereum-like blockchains, highlighting differences in protocol form, storage, immutability, minting, scarcity, royalties, and energy profiles, and they survey a range of use cases from digital art to gaming and messaging. The paper also identifies challenges such as bloat, limited smart-contracts, and security and governance concerns, and outlines opportunities in inscription derivatives, Layer2 BTC solutions, and cross-chain interoperability to guide future research and development.
Abstract
Bitcoin inscription marks a pivotal moment in blockchain technology. This report presents a primary exploration of Bitcoin inscriptions. We dive into the technological underpinnings and offer a detailed comparative analysis between Bitcoin inscriptions and NFTs on other blockchains. Further, we explore a wide range of use cases and significant opportunities for future innovation, including inscription derivative protocols, Bitcoin Layer2 solutions, and interoperability techniques.
