The post Blockchain Legend Nick Szabo Breaks 5-Year Silence Amid Bitcoin Core v30 Controversy appeared first on Coinpedia Fintech News
Legendary cryptographer Nick Szabo is back online after five years, and he’s diving straight into one of Bitcoin’s hottest debates.
The creator of Bit Gold, often called a precursor to Bitcoin, shared his thoughts on the controversial Bitcoin Core v30 update and a recent $44 million BTC move that has the crypto community talking.
Here’s the chatter.
Bitcoin Core v30: Big Changes Ahead
The Bitcoin Core team recently released v30.0rc2, the second test version of their major update. It brings a new wallet format, phases out old wallets, and simplifies command systems.
The real debate, however, is about OP_RETURN, a feature that lets users embed data in transactions. Its limits are set to rise from 80 bytes to potentially 4 MB per transaction output.
Bitcoin purists argue this is risky. They say the network should focus on financial transactions, warning that storing large amounts of data could bloat the blockchain, raise costs, and open the door to spam or malware.
Maximalists counter that users paying fees should be free to use block space however they want, and the market will naturally limit misuse.

Szabo Weighs In
Szabo didn’t hold back.
On X, he said: “Fees protect the miners, but they don’t provide enough disincentive to protect the full nodes. This has always been a problem, of course. But increasing the OP_RETURN allowance will likely make this problem worse. It will also increase legal risks.”
His return adds weight to the conversation as Bitcoin Core v30 approaches its likely release in late October.
Legal Risks Loom Large
The legal angle is tricky. Node operators could face liability if illegal content is stored on the blockchain.
Szabo pointed out: “Illegal content in a standard format, thus readily viewable by standard software, is more likely to impress lawyers, judges, and jurors, and thus is legally more risky, than data that has been broken up or hidden and thus requires specialized software to reconstruct.”
This intersects with regulations like California’s AB 1052, which could classify coins untouched for three years as unclaimed property.
$44M BTC Moves Spark Speculation
Earlier this week, a 2013 Bitcoin address moved 400 BTC, worth around $44 million. Some linked it to “Salomon Brothers” notices or possible state seizure.
Szabo explained: “I think this is somebody moving their Bitcoin to other addresses in preparation for such a law, while at the same time protesting the law. (P.S. for security as well as such legal reasons, it’s a good idea to move your Bitcoin every few years).”
Whether for legal caution, security, or protest, it highlights the mix of regulation, tech updates, and market moves shaping Bitcoin today.
With v30 updates, OP_RETURN debates, legal risks, and large BTC moves, Bitcoin is at a turning point and Szabo is encouraging conversation.
