Bitcoin core developer Luke Dashjr has denied any involvement in adding Bitcoin inscriptions to the United States National Vulnerability Database’s (NVD) Common Vulnerabilities and Exposure (CVE) list. Dashjr had previously claimed that inscriptions exploit a vulnerability in Bitcoin Core to spam the blockchain. However, despite being a critic of Bitcoin inscriptions, Dashjr stated that he did not play a role in adding them to the CVE list.
The CVE list allows any developer to report a vulnerability, and it is typically included if the CVE Assignment Team deems it important for public awareness. On December 11, the NVD updated the listing for inscriptions and assigned it a base severity score of “5.3 Medium.” This score indicates that the vulnerability provides limited access to a network or is difficult to execute denial of service attacks.
Dashjr argued that the score may underestimate the long-term impact of blockchain bloat caused by inscriptions. He suggested that if the availability impact was classified as “High,” the CVSS base score would be 7.5. The debate around the nature of Bitcoin inscriptions continues, with some claiming they are spamming the network while others argue they are crucial for the Bitcoin network’s future adoption and revenue generation.
The Bitcoin network has experienced increased congestion due to the popularity of Ordinals nonfungible token (NFT) inscriptions and BRC-20 token minting. There are currently over 275,000 unconfirmed transactions, and transaction costs have risen significantly. Patching the Inscriptions bug could potentially restrict future Ordinals inscriptions on the network.
Overall, the controversy surrounding Bitcoin inscriptions and their impact on the Bitcoin network continues to be a topic of discussion among developers and Bitcoin enthusiasts.
