Bitcoin core developer Luke Dashjr has denied playing any part in adding Bitcoin inscriptions as a cybersecurity risk on the United States National Vulnerability Database’s (NVD) Common Vulnerabilities and Exposure (CVE) list.

Dashjr courted controversy in a Dec. 6 post to X (formerly Twitter) claiming that inscriptions — used by the Ordinals protocol and BRC-20 creators to embed data on satoshis — exploit a Bitcoin Core vulnerability to “spam the blockchain.”
