rewrite this title Is There a Moral Obligation to Prevent Gambling Applications on Blockchains?

Blockchain is transforming industries, but there’s one trend that has some people—especially Ethereum’s Vitalik Buterin—raising an eyebrow: the growing influence of crypto gambling. Should blockchain platforms take a stand against it, or is it all just part of the game?

During a February 20 AMA, Buterin didn’t hold back. He pushed back against claims that Ethereum is “bad and intolerant” for not fully embracing blockchain casinos, making it clear that he’s not a fan of prioritizing profits over ethics. 

Unlike other blockchains that openly welcome gambling applications, Ethereum has kept its distance. And if things keep heading in a direction he’s uncomfortable with, Buterin hinted that he might just walk away from the space altogether.

His concerns highlight a deeper debate within the crypto world: Should blockchain be a neutral, open-for-all technology, or should developers set ethical boundaries? It’s a classic clash between decentralization and social responsibility, and the stakes couldn’t be higher.

The Allure of Blockchain Tech in Gambling

Blockchain-based gambling is experiencing rapid growth, driven by technological advancements and shifting consumer preferences. This surge is fueled by increasing internet penetration and the widespread use of mobile devices, making online gaming more accessible than ever.

According to a report by Grand View Research, the global online gambling market was valued at $63.53 billion in 2022 and is projected to expand at a compound annual growth rate (CAGR) of 11.7% from 2023 to 2030.

The adoption of blockchain technology has significantly impacted market growth, with many platforms now accepting cryptocurrency payments alongside traditional methods.

Blockchain gambling has been hailed as a revolution in fairness and transparency. Its transparent ledgers ensure secure transactions, reducing fraud while streamlining the gaming experience. Also, thanks to smart contracts, players can verify game outcomes, eliminating concerns about rigged results. No shady algorithms, no hidden house edge—just provable fairness.

Platforms like BitStarz thrive on these advantages, drawing users who value security and trustless systems. However, as adoption grows, so do concerns about potential harm.

While blockchain empowers financial independence, it also introduces risks—especially in gambling. The anonymity and speed of crypto transactions can fuel excessive betting habits, making it easier for problem gamblers to spiral out of control without oversight.

Unlike traditional casinos in regulated markets like the UK and US, which enforce anti-money laundering (AML) and know-your-customer (KYC) rules, many blockchain-based gambling platforms exist in legal grey zones, so they offer little to no protection for vulnerable users.

But the risks don’t stop there. Crypto’s financial volatility adds another layer of uncertainty. Unlike fiat-based casinos, where winnings maintain a stable value, blockchain gamblers face unpredictable swings. A jackpot worth thousands today could be worth half as much tomorrow. This level of financial instability introduces risks that traditional gambling platforms simply don’t impose, making it even harder for players to walk away with consistent winnings.

The dangers of unchecked gambling aren’t hypothetical. Jordan Lea’s story is a chilling example. Starting at just 14 years old, he gambled online and racked up debts of nearly £500,000 before his financial collapse in his late 20s. Stories like Lea’s highlight the risks of unregulated gambling, sparking debate on whether platforms should intervene or uphold the principle of personal responsibility.

Lessons from The Tobacco and Alcohol Industries: Ethical Regulation vs. Profit Maximization

The ethical dilemmas surrounding blockchain gambling are not unprecedented. Throughout history, industries that profit from potentially harmful behaviors such as tobacco and alcohol have faced scrutiny over the balance between corporate profit and public well-being. In each case, societies have had to decide whether to impose outright bans, implement regulations, or leave individuals to navigate the risks on their own. These past battles offer crucial insights into how blockchain gambling might evolve, particularly as concerns about addiction, financial harm, and regulatory loopholes continue to grow.

One of the clearest parallels can be drawn from the tobacco industry, which thrived for decades under minimal regulation despite mounting evidence of its health risks. Cigarette companies marketed aggressively, targeting even young consumers while funding research to obscure the dangers of smoking.

As smoking-related illnesses reached crisis levels, governments were forced to act, introducing age restrictions, advertising bans, health warnings, and heavy taxation. Laws such as the Tobacco Master Settlement Agreement (1998) in the U.S. and the World Health Organization’s Framework Convention on Tobacco Control (2005) set a precedent for ethical intervention—not through prohibition, but by mitigating harm while preserving individual choice.

Blockchain gambling finds itself in a similar legal gray zone, where the absence of oversight leaves individuals vulnerable. The lesson here is clear: industries that prioritize profits over public welfare will inevitably face intervention. Rather than waiting for governments to impose sweeping regulations, blockchain gambling platforms could take proactive measures such as on-chain spending limits, player self-exclusion tools, and mandatory risk disclosures to promote responsible gaming, much like cigarette packaging now carries explicit health warnings.

The alcohol industry offers another cautionary tale. In the early 20th century, the U.S. government attempted to eliminate alcohol-related social harms through Prohibition (1920–1933), banning its production and sale. However, rather than eradicating the problem, this policy drove the alcohol trade underground, fueling organized crime, illicit speakeasies, and a thriving black market. 

Recognizing the failure of total prohibition, policymakers reversed course, opting instead for harm-reduction strategies such as age restrictions, licensing requirements, and public awareness campaigns. This shift established a model of regulated consumption that continues today, balancing economic incentives with social responsibility.

The same lessons apply to blockchain gambling. A complete crackdown on crypto casinos could push players toward riskier, unregulated alternatives, just as Prohibition-fueled bootlegging. However, responsible regulation—rather than outright bans—could create a safer environment without stifling the industry’s innovation. Much like alcohol laws require ID verification and responsible drinking campaigns encourage moderation, blockchain gambling platforms could implement blockchain-based KYC (Know Your Customer) checks, spending limits, and educational campaigns on the risks of gambling.

Ultimately, both the tobacco and alcohol industries illustrate that leaving high-risk industries unchecked leads to public harm, regulatory intervention, and unintended consequences. However, proactive self-regulation through transparency, consumer protection measures, and ethical governance can help industries evolve responsibly. In the case of blockchain gambling, the industry has a rare opportunity to learn from history and introduce responsible gaming measures before external forces impose them. Implementing on-chain safeguards, player protections, and decentralized governance models could ensure that blockchain gambling remains fair, ethical, and sustainable—striking a balance between decentralization and consumer protection.

Should Blockchain Platforms Impose Moral Restrictions?

The debate over blockchain gambling isn’t just about technology or profits—it’s about values. Should blockchain remain a neutral infrastructure where users bear full responsibility for their actions, or does the industry have a duty to step in when harm becomes evident?

On the one hand, the libertarian ethos of blockchain champions decentralization and personal choice, arguing that restricting gambling applications contradicts the very principles of the technology. On the other, the real-world consequences—problem gambling, financial ruin, and regulatory loopholes—raise serious ethical concerns that can’t be ignored.

The reality is, as it is now, blockchain gambling exists in a grey zone. It offers fairness and transparency through provable outcomes but also enables unchecked risks due to anonymity and regulatory gaps.

Interestingly, blockchain itself may hold the key to a more balanced approach. Decentralized Autonomous Organizations (DAOs) like MolochDAO and Gitcoin Grants show that decentralized communities can collectively fund or restrict applications based on ethical considerations. These models suggest that crypto doesn’t have to be a lawless frontier—it can innovate while still being accountable.

So, rather than a binary choice between total restriction and complete freedom, the most viable path forward lies in responsible innovation—smart contract safeguards, community governance, and age verification mechanisms that uphold ethical gaming without sacrificing decentralization.

We should not only be asking whether blockchain gambling ought to exist. The focus should be on whether the industry can evolve beyond short-term gains and proactively shape an ecosystem that prioritises both innovation and consumer protection. The answer to that will ultimately define blockchain’s legacy—not just in gambling but also in its broader quest to revolutionise finance and technology.
