Hoskinson Warns Section 604 Removal Would Create 'Dystopian Nightmare'

A single provision inside the proposed Digital Asset Market Clarity Act has become a flashpoint that could redefine legal liability for every open-source developer in crypto. The National Fraternal Order of Police (FOP) sent a letter to Senators Tim Scott and Elizabeth Warren urging them to remove Section 604, the part of the bill that would exempt non-controlling developers and infrastructure providers from being classified as money transmitters. Charles Hoskinson, founder of Cardano, responded by calling the removal push "insanity" and a "dystopian nightmare" for software development. The immediate market reaction was muted. The legislative fight exposes a risk that reaches far deeper than a single bill. It strikes at the legal foundation that allows permissionless blockchains to operate inside U.S. jurisdiction.

The simple read is that law enforcement wants to close a loophole. The FOP argues that shielding developers from money transmitter liability would make it harder to prosecute criminal networks that use decentralized platforms. The better market read is that removing Section 604 would attach unbounded, perpetual legal exposure to the act of publishing open-source code. That mechanism would not just chill innovation. It would actively push development of public blockchain infrastructure outside the United States, shifting liquidity, talent, and protocol control to jurisdictions with clearer safe harbors.

The FOP Letter and the Money Transmitter Red Line

Section 604 of the Digital Asset Market Clarity Act draws a line between financial intermediaries and software publishers. It states that a person who merely writes or distributes code, without controlling how others use it, is not a money transmitter. The FOP letter asks Senators Scott and Warren to erase that line. FOP President Patrick Yoes wrote that the exemption would weaken prosecutors' ability to target criminal networks using digital assets. The letter frames the provision as a gift to illicit finance.

What the FOP Letter Actually Requests

The FOP is not asking for a minor amendment. It is asking for the removal of the entire developer safe harbor. Without Section 604, the default legal standard would revert to a functional test: if software facilitates value transfer, the person who wrote or deployed it could be treated as a financial intermediary. That standard does not require knowledge of the specific criminal act. It does not require a relationship with the user. It only requires that the software was used.

The Political Framing

The FOP letter frames the issue as a choice between catching criminals and protecting developers. That framing is politically potent. The counterargument, which Hoskinson and other industry voices are making, is that the choice is false. Removing Section 604 would not stop criminals from using decentralized tools. It would simply push the development of those tools outside U.S. borders, where law enforcement has less visibility and fewer levers. The practical effect would be weaker, not stronger, oversight of the very networks that concern the FOP.

Hoskinson's Infinite Liability Warning

Hoskinson rejected the FOP's logic in a public statement that quickly circulated across crypto policy circles.

The insanity of their position is beyond any sense of reason. You develop open source software, you give it to the world, someone else who you've never met does something with it without your knowledge or consent, and then you're forever liable for THEIR ACTIONS.

His argument isolates the structural problem: liability without control and without end. A developer who releases code under an open-source license today could face prosecution a decade later for a transaction they never saw, initiated by a person they never met, on a network they no longer maintain. That is not a theoretical risk. It is the logical endpoint of removing the Section 604 distinction between publishing code and operating a money services business.

The Comparison to Authors and Fiction

Hoskinson also compared the logic behind the proposal to blaming authors for crimes inspired by fictional books. The comparison highlights what he sees as the absurdity of assigning criminal liability to creators for independent actions carried out by strangers. The analogy is extreme, yet it captures the core legal problem: removing Section 604 would collapse the distance between a creator's intent and a user's independent act.

Which Assets Carry the Highest Developer Liability Exposure

The assets most exposed to a Section 604 removal are not limited to one chain. The risk runs across every smart contract platform, layer-2 network, and DeFi protocol that relies on open-source contributions from developers who do not control user funds.

Smart Contract Platforms Face the Sharpest Risk

Ethereum and Solana host the largest concentrations of open-source DeFi code. Core developers, wallet builders, and smart contract authors on these networks typically do not custody user assets. Under current U.S. guidance, they are not money transmitters. If Section 604 is stripped from the bill, that assumption collapses. The legal exposure would extend to anyone who wrote or deployed a smart contract that later processed a sanctioned transaction or a ransomware payment. The chilling effect would be immediate: developers would face a binary choice between relocating outside U.S. reach or abandoning permissionless infrastructure entirely.

The Senate Banking Committee's Next Move

The Digital Asset Market Clarity Act is still in draft form and has not yet reached a committee vote. The FOP letter signals that law enforcement groups intend to make Section 604 a central point of contention. Senators Scott and Warren sit on the Senate Banking Committee, which would handle the bill. Both have taken active roles in crypto legislation, though from different angles. Scott has pushed for innovation-friendly frameworks. Warren has focused on illicit finance risks.

Committee Dynamics

The committee's composition means the Section 604 fight will not break cleanly along party lines. Some Democrats will side with law enforcement and push for removal. Some Republicans will defend the developer safe harbor. The outcome depends on whether a compromise emerges, such as a narrowed exemption that still protects core developers but excludes those who actively promote illicit use. No such compromise language has been proposed yet.

The Broader Regulatory Context

The controversy reflects a much broader fight currently happening in Washington over how cryptocurrency infrastructure should be regulated. Supporters of Section 604 argue that developers who merely publish code should not automatically be treated as financial intermediaries. Opponents, including some law enforcement groups, fear that those protections could create loopholes that criminals exploit through decentralized platforms and anonymous blockchain tools. The outcome of the debate could carry major consequences for the future of decentralized finance and open-source crypto development in the United States. If regulators move toward stricter liability standards, developers may increasingly relocate innovation outside U.S. jurisdiction or shift toward heavily controlled systems that sacrifice decentralization entirely.

Scenarios: De-escalation and Amplification

The Section 604 risk is not yet priced as a base case. Most market participants assume that some form of developer safe harbor will survive, either in the Clarity Act or in separate legislation. That assumption could be wrong. The FOP letter is the first organized push from a major law enforcement group to remove the provision entirely. If other groups join, the political calculus shifts.

What Would De-escalate the Risk

The clearest de-escalation signal would be a public statement from Senators Scott or Warren affirming support for Section 604 or a similar safe harbor. That would indicate that the FOP letter did not move the committee's position. A second de-escalation path would be the introduction of compromise language that narrows the exemption without eliminating it, for example by excluding developers who knowingly design code for illicit purposes. That would preserve the core protection while addressing law enforcement's stated concern. A third path is procedural: if the bill stalls and the safe harbor debate moves to a later legislative vehicle, the immediate risk recedes, though it does not disappear.

What Would Amplify the Fallout

The amplification scenario begins with additional law enforcement endorsements of the FOP position. If the Department of Justice or the Financial Crimes Enforcement Network signals support for removing Section 604, the political pressure on the Banking Committee would intensify sharply. A second amplifier would be a high-profile criminal case in which prosecutors argue that a developer should be treated as a money transmitter under existing law. That would turn a legislative risk into an immediate legal reality, even before the bill moves. The third amplifier is the simplest: the bill advances with Section 604 removed. At that point, the liability shift stops being a risk event and becomes a structural change that every U.S.-based crypto developer must navigate immediately.

Risk to watch: A broad interpretation of money transmitter rules could turn every smart contract deployer into a potential defendant, regardless of intent or control.

The debate over Section 604 is not about whether crypto should be regulated. It is about whether the act of writing code can be treated as a financial service. The answer will determine whether open-source blockchain development remains viable inside the United States or becomes an activity that only happens elsewhere. For traders, the assets that look cheapest today are often the ones where a slow-moving legal risk has not yet been priced. Section 604 is exactly that kind of risk.
