‘Bitcoin Inscriptions’ Listed in the US National Vulnerability Database
The US National Vulnerability Database (NVD) recently identified "inscriptions" created within the Ordinals protocol as a cybersecurity threat to the Bitcoin network.
This warning points to the possibility of circumventing data volume limitations transmitted through transactions in some versions of Bitcoin Core and Bitcoin Knots, using BRC-20. Such data can be disguised as code.
Inclusion of this vulnerability in the NVD database means it has been thoroughly studied and recognized as worthy of public attention.
An "inscription" represents additional data entered into a specific satoshi, which can be any digital media, such as an image or text. Since they become a permanent part of the blockchain, this leads to an increase in its size with each created bitcoin-NFT.
The main threat from this vulnerability is the spread of non-transactional data and spam, negatively impacting network performance and increasing fees.
Previously, the Ordinals protocol had already caused overload in the Bitcoin blockchain.
The NVD website also mentions a recent publication by Bitcoin Core developer Luke Dash Jr., criticizing Ordinals for cluttering the network and calling for the censorship of such transactions.
Despite potential risks, the protocol continues to be popular. According to Dune, since the project's inception, more than 47.2 million bitcoin-NFTs have been created, with over $151 million spent on related fees.
