Bitcoin may not be as resistant to network attacks as many believe, according to Bitcoin pioneer Nick Szabo. While Bitcoin is designed as a trust-minimized system, Szabo argues it isn’t completely trustless and remains vulnerable to interference from nation-states and large corporations.
In a post on X on Sunday, Szabo explained that every cryptocurrency and layer-1 blockchain has a “legal attack surface”—a point of vulnerability that governments can exploit to disrupt or pressure the network.
Believing that Bitcoin or any blockchain protocol is a “magical anarcho-capitalist Swiss army knife that can withstand any kind of governmental attack in any legal area is insanity,” he wrote.
Szabo’s comments carry significant weight in the crypto world. He is widely recognized as an early innovator of smart contracts, and some have even speculated that he might be Bitcoin’s elusive creator, Satoshi Nakamoto, due to his development of the Bit Gold concept in 1988. Szabo, however, has repeatedly denied being Nakamoto.
In a follow-up post, Szabo argued that coordinated action against Bitcoin miners, node operators, and wallet providers is possible in jurisdictions that strongly enforce the rule of law. His concern centers on “arbitrary data” and the possibility that regulators could compel network participants to delete or alter certain content, effectively forcing them to manipulate the blockchain.
Ordinals and Runes at the Core of the Debate
Szabo’s warning connects to the ongoing, months-long dispute between Bitcoin Core and Bitcoin Knots supporters over whether non-financial content—such as images, videos, and audio embedded via Ordinals, Runes, and BRC-20 transactions—belongs on the Bitcoin network.
In recent months, Bitcoin Knots has gained significant node-validator market share as some Bitcoiners expressed frustration with Bitcoin Core developers. Their criticism focuses on the implementation of the controversial OP_RETURN function, which many argue contributes to an influx of “spam” transactions clogging the network.
Nick Szabo Faces Pushback
Szabo’s comments drew strong reactions from several Bitcoin advocates, including Chris Seedor, CEO of the wallet-backup firm Seedor. Seedor argued that Szabo is overstating the threat posed by hypothetical regulatory “boogeymen.”
“Bitcoin’s resilience was never about predicting every possible domain of law — it was about minimizing technical points where coercion can bite,” Seedor said. He added that if regulators truly had such power, they would have already taken down technologies like PGP, Tor, and other censorship-resistant protocols.
