The renowned Bitcoin Core developer Luke Dashjr recently disclosed a serious flaw in the programme that he dubbed “Inscription,” which is part of the Bitcoin Core. The blockchain’s defence against spam may have a weakness, as this discovery has sparked concerns in the cryptocurrency community.
Breaking down the issue
According to Dashjr, Dashjr, Bitcoin Core users have been able to set limits on extra data in transactions using the -datacarriersize setting since 2013. The clever Inscription method, on the other hand, has found a way around this limitation by concealing its data as program code.
This deft manoeuvre effectively circumvents the intended constraints, resulting in what Dashjr refers to as “spamming the blockchain.” While Bitcoin Knots v25.1 addressed this issue, Bitcoin Core remains vulnerable in its upcoming v26 release. The community is hoping for a fix before the anticipated release of v27 next year.
