The US National Vulnerability Database (NVD) has identified that BRC-20 standard tokens exploit a vulnerability in the Bitcoin code.
According to the official announcement, BRC-20 tokens in some versions of the backbone of the network builders Bitcoin Core and Bitcoin Knots bypass the established restrictions on the size of additional information contained in the “inscriptions”. The Ordinals protocol allows them to obfuscate data by disguising it as code, as one code developer previously discussed.
PSA: “Inscriptions” exploit a vulnerability in #Bitcoin Core to spam the blockchain. Since 2013, Bitcoin Core has allowed users to limit the size of additional data in transactions they forward or mine (“-datacarriersize”). By disguising their data as program code,…

The agency has flagged “inscriptions” created using the Ordinals protocol as a cybersecurity threat to the Bitcoin (BTC) network. Inclusion in the NVD database means that the identified vulnerability has been determined to be of high public awareness. However, it is still in the analysis stage.
The agency also emphasized that BRC-20 has already heavily clogged the first cryptocurrency network. According to representatives, this will negatively impact blockchain performance and transaction fees.
BRC-20 is an experimental token standard on the BTC network. It “labels” satoshis, the smallest unit of Bitcoin, with JavaScript Object Notation (JSON) data.
This allows the coin to be staked, minted and transferred. Such tokens appeared against the backdrop of the crypto community's enthusiasm for the Ordinals protocol, which was launched in early 2023. It allows non-fungible tokens (NFTs) to be added to Satoshi.
Due to the increased excitement, the blockchain of the first cryptocurrency was congested fivefold. The average transaction value increased to $14 to $16.
