A netizen asked, "If inscriptions want to continue, a more environmentally friendly method is to create an 'inscription chain', similar to Ethereum's Layer 2. This chain only needs to submit hashroot to Bitcoin regularly to run, right?" Bitcoin core developer Luke Dashjr replied, "Yes, that works. And it doesn't even need to have a block size limit. Each node can set its own limit value (or not set a limit)." Earlier, Bitcoin core developer Luke Dashjr wrote on X platform, "Inscriptions are using a vulnerability in the Bitcoin Core client to send garbage information to the blockchain. Since 2013, Bitcoin Core has allowed users to set additional data size limits when relaying or mining transactions. By blurring their data into program code, inscriptions bypassed this limit. This vulnerability was recently fixed in Bitcoin Knots V25.1. Due to serious disruptions in my workflow at the end of last year (V24 was completely skipped), the fix took longer than usual. In the upcoming V26 version, Bitcoin Core still has vulnerabilities. I can only hope that it will be finally fixed before V27 next year." In response to netizens' comments, Luke Dashjr said that after the vulnerability is fixed, it means that Ordinals and BRC-20 will no longer exist.
