Prominent Bitcoin developer Luke Dashjr denies involvement in recently categorizing Bitcoin transaction inscriptions as a cyber vulnerability on the U.S. government's National Vulnerability Database (NVD).

Dashjr sparked controversy last week calling inscriptions — used to embed collectible NFT data via the Ordinals protocol — an exploit "spamming" Bitcoin's blockchain. Days later, inscriptions appeared on the NVD Common Vulnerabilities list.

But despite past criticisms, Dashjr claims no role in the surprise NVD designation. He argues the "medium severity" score downplays long-term blockchain bloat risks that may require future mitigation.

Inscriptions facilitate novelty non-fungible tokens on Bitcoin's base layer. Supporters consider them a crucial next wave of network functionality and revenue. Critics say negligible utility drives harmful congestion.

Regardless of Dashjr's involvement, the vulnerability categorization itself signifies the debate reaches beyond social media battles. Restricting future inscription capacity would directly impact emerging Bitcoin business models.

For now, both sides appear digging in on opposing viewpoints airing technical and philosophical differences. But real-world implications loom as narratives shape ecosystem development and technological progress in months ahead.
