A bug fix on the Bitcoin network has been implemented to address a vulnerability that was being exploited by Bitcoin Ordinals and BRC-20 tokens. These tokens were causing network congestion by spamming the blockchain with inscriptions, which bypassed the limits on the size of extra data in transactions. The bug allowing inscriptions to bypass these limits has been fixed in the latest update to Bitcoin Knots, a derivative of Bitcoin Core. As a result, the blocks on the Bitcoin network will now include more legitimate transactions and the congestion caused by inscriptions and BRC-20 token minting should be alleviated.The developer, Luke Dashjr, who is also the chief technology officer of the decentralized mining protocol Ocean, has been vocal about the negative impact of Ordinal inscriptions on Bitcoin. He believes that the damage caused by these inscriptions is significant and irreversible. Dashjr hopes that the vulnerability will be completely fixed in the upcoming release of Bitcoin Core.The Ordinals protocol, launched in January 2023, allowed users to inscribe data and nonfungible tokens onto satoshis, the smallest unit of Bitcoin. However, Dashjr claims that Ordinals were never allowed and considers them to be an attack on Bitcoin.The Bitcoin network has experienced increased congestion due to the influx of inscriptions and BRC-20 token minting. This has resulted in a large number of unconfirmed transactions and higher transaction costs.Overall, the bug fix on the Bitcoin network is expected to address the vulnerability exploited by inscriptions and improve the efficiency of the network.
