Jimmy Song, a Bitcoin
BTC$114,510developer and advocate, slammed the decision by Bitcoin Core developers to remove the OP_Return limit for non-monetary data embedded on the Bitcoin blockchain in the upcoming Bitcoin Core 30 upgrade, calling it “fiat” mentality.
Song accused the Core developers of deflecting user concerns about removing the OP_Return limit, which is currently 80 bytes in size, and ignoring the significant pushback from the Bitcoin community and node runners. He also said:
“The idea that spam is difficult to define, and because of this ambiguity, we shouldn't be making any distinctions at all in the software, is a time-wasting argument from fiat politics where you pretend not to know the obvious, so the actual debate can never get off the ground — the non-monetary uses of Bitcoin are spam.
You can argue whether that's something desirable or not, but saying you can't define it is a stalling tactic meant to avoid the real argument about actual impact — particularly, the long-term impact of this change,” Song continued.

The OP_Return debate has raged on for nearly six months, and is reminiscent of the Bitcoin block size wars that took place between 2015 and 2017, which eventually resulted in a hard fork of the Bitcoin protocol that spawned Bitcoin Cash
BCH$587.60, leading some in the Bitcoin community to speculate if the OP_Return wars will result in a similar split.
The decision by Bitcoin Core devs to unilaterally blow open the OP_Return data limit has left the Bitcoin community divided and driven record numbers of Bitcoin node runners to Bitcoin Knots, an alternative implementation of the Bitcoin node software.
This surge in nodes running Bitcoin Knots, which now account for about 20% of the network, compared to about 1% in 2024, represents a near-vertical leap in just nine months.
