Bitcoin core developer calls Ordinals a “vulnerability” for the BTC blockchain

Bitcoin community on the internet is embroiled in a debate on whether Ordinals are a vulnerability to the BTC blockchain. While Bitcoin core developers like Luke Dashjr consider inscriptions as spam, they are being considered an evolution of the BTC blockchain by others, on the social media platform X.

Ordinals are now identified as a vulnerability

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. 

The developer argues that miners are expected to be honest and not malicious, however allowing inscriptions on the Bitcoin blockchain racks up the transaction fees. While it is beneficial to miners, it is an attack on the BTC blockchain network. 

Inscriptions are considered a technical vulnerability that could influence Bitcoin users in the long term as a result of its impact on the network’s security and integrity. 

At the time of writing, Bitcoin price is $43,694 on Binance. The asset yielded nearly 11% gains for BTC holders on Binance, in the past week.
