<h4><strong>Luke Dashjr, a Bitcoin Core developer, has raised concerns about a new form of exploitation known as “Inscriptions.” </strong></h4> 
<p>These inscriptions are capitalizing on a vulnerability within Bitcoin Core. Using a clever technique to spam the blockchain and potentially threaten its sustainability.</p> 
<h5><strong>Bitcoin’s Vulnerability Over Inscriptions</strong></h5> 
<p>The vulnerability that Inscriptions are exploiting revolves around a feature implemented in Bitcoin Core since 2013. Bitcoin Core allows users to set a limit on the size of additional data in transactions they relay or mine. This feature was intended to prevent the blockchain from becoming bloated with unnecessary information, maintaining its efficiency and scalability. However, Inscriptions have found a way to circumvent this limitation.</p>

<p>By disguising their data as program code, Inscriptions manage to bypass the size limit set for extra data in Bitcoin transactions. This obfuscation technique allows them to flood the blockchain with seemingly legitimate transactions, causing congestion and potential disruptions to the network. Luke Dashjr has brought attention to this loophole, emphasizing the need for prompt action to address the threat posed by Inscriptions.</p> 
<h5><strong>Impact on Blockchain Sustainability</strong></h5> 
<p>The influx of Inscriptions poses a significant threat to the sustainability of the Bitcoin blockchain. The increased congestion resulting from these obfuscated transactions can lead to delayed confirmations and higher <a href="https://www.altcoinbuzz.io/?s=transaction+fees" target="_blank" rel="noopener">transaction fees</a> for regular users. Moreover, the scalability of the blockchain is jeopardized, as the network struggles to cope with the additional load imposed by Inscriptions.</p>

<p>This threat is not merely a technical inconvenience but a challenge to the very foundations of the blockchain’s functionality. Blockchain technology relies on a delicate balance of security, decentralization, and efficiency. The exploitation of vulnerabilities, such as that being utilized by Inscriptions, undermines this balance and raises questions about the long-term viability of the Bitcoin blockchain.</p> 
<h5><strong>Potential Solutions</strong></h5> 
<p>Addressing the inscription threat requires a multifaceted approach. Bitcoin Core developers are actively working to identify and patch the vulnerability that allows for this exploitation. However, as the battle between developers and malicious actors continues, a more sustainable solution is needed.</p> 
<p>One proposal gaining traction is to relegate Inscriptions to operate on Layer 2 (L2) blockchains, such as <a href="https://www.altcoinbuzz.io/?s=stacks" target="_blank" rel="noopener">Stacks</a> or Rootstock. Moving these activities to a secondary layer helps alleviate the strain on the primary blockchain. Allowing it to maintain efficiency and scalability. L2 solutions have been explored as a means to offload some transactions from the main blockchain, creating a more streamlined and adaptable network.</p>
