Ordinals are now identified as a vulnerability

Bitcoin Core developer, Luke Dashjr, told his 83,300 followers in a recent tweet on X that inscriptions are exploiting a vulnerability in Bitcoin Core to spam the blockchain. Since 2013, Bitcoin Core allows users to set a limit on the size of extra data in transactions that they relay. Inscriptions bypass this limit and this makes them a “vulnerability.”

Dashjr says that Bitcoin Core is still vulnerable in the upcoming v26 release and the developer hopes to finally fix the issue before v27 next year.

Integrating Ordinals into Bitcoin can be likened to the act of spraying neon graffiti on revered ancient monuments like the colosseum or the pyramids. These structures stand as architectural marvels and testaments of historical significance. Imagine them suddenly covered in flashy, modern neon spray paint.

In a similar vein, the introduction of Ordinals into Bitcoin feels like a significant misstep. It disrespects and distorts the foundational principles of Bitcoin, turning a groundbreaking financial innovation into a cluttered display of digital extravagance. This transformation not only undermines the original vision of Bitcoin but also challenges the very essence of what made it a monumental breakthrough in the digital world.
