<p>In a detailed announcement, Dashjr revealed that the issue stems from a vulnerability in Bitcoin Core, allowing users to set a limit on the size of additional data in transactions since 2013 (-datacarriersize). Exploiting this vulnerability, Inscriptions obfuscate their data as program code, thereby surpassing this set limit.</p>
<p>While the bug has been addressed in Bitcoin Knots v25.1, Dashjr notes that its resolution was delayed due to disruptions in his workflow at the end of the previous year, resulting in the complete omission of v24.</p>
<p>Responding to queries on the implications of fixing this vulnerability, Dashjr clarified that after the issue is resolved, <a href="https://decrypt.co/resources/what-are-ordinals-a-beginners-guide-to-bitcoin-nfts" target="_blank" rel="noopener noreferrer nofollow">Ordinals</a> and BRC-20 will cease to exist. This information was shared in response to community queries seeking clarity on the consequences, with one user expressing confusion and requesting an explanation in simple terms.</p>
<p>In response to the plea for clarity, Dashjr affirmed that the resolution of this bug would indeed eliminate <a href="https://cryptonewsland.com/bitcoin-ordinals-inscriptions-surpass-10-million-80-linked-to-brc-20-tokens/" target="_blank" rel="noopener noreferrer nofollow">Ordinals and BRC-20</a> tokens. However, he emphasized the distinction between <a href="https://cryptonewsland.com/ethereum-vs-bitcoin-will-eth-futures-etf-seal-the-victory/" target="_blank" rel="noopener noreferrer nofollow">Bitcoin and Ethereum</a>, highlighting that developers in the Bitcoin space lack full decision-making power.</p>
<p>As the Bitcoin community awaits the release of v27 with the anticipated fix, Dashjr’s commitment underscores the ongoing efforts to maintain the integrity and security of the Bitcoin blockchain.</p>
