Andreas Antonopoulos Is Right About OP_RETURN

I’ve seen Matthew Kratter attack Andreas Antonopoulos, calling him a “woke” shitcoiner and others getting upset because Andreas compared the Bible to garbage. Sure, that comparison wasn’t polite. But responding with personal attacks, rather than engaging with his actual arguments about OP_RETURN is pure ad hominem. It does nothing to refute his point.

I learned a lot from Andreas. Many of the people now criticizing him for writing Mastering Ethereum seem to forget that his Mastering Bitcoin helped raise an entire generation of Bitcoin developers. You don’t get to erase that contribution just because you dislike some of his later positions.

I also have strong disagreements with some of Andreas’s views. But criticizing those ideas doesn’t automatically invalidate the rest of what he says. That kind of all-or-nothing thinking only makes sense if you believe certain people are always right or always wrong. Reality isn’t that simple.

To be clear, I personally stopped following Andreas on X years ago. He presented himself as a libertarian while simultaneously advocating mandatory vaccines and proudly banning “anti-vaxxers” and “conspiracy theorists.” I also remember him on Joe Rogan criticizing the Federal Reserve not for being an anti-capitalist institution that centrally controls money and capital allocation, but for being a private entity. In my view, he misdiagnoses the core problem there.

Technically, though, Andreas is exceptionally sharp. He’s helped countless people, technical or non-technical understand Bitcoin. I’m one of them. But it has always frustrated me that he doesn’t seem to grasp why there will ultimately be only one dominant store of value and why Bitcoin is the inevitable winner, not Blockchain or “crypto”.

Still, pointing out those flaws doesn’t make his arguments about OP_RETURN wrong. His language or personal worldview doesn’t change the technical or philosophical validity of his position.

His core point is important: Bitcoin already has one filter: transaction fees. Introducing additional filters, like those proposed in BIP-444, is a dangerous slippery slope. If developers gain the power to censor certain transactions, they will eventually be expected to censor! That’s the risk Andreas is warning about and it deserves to be addressed on its merits, not dismissed because of unrelated disagreements.
