From Cypherpunks to Corporates: Crypto’s Crossroads
What began as a radical movement for transparency is now drifting into corporate territory. Once defined by open code and decentralized ideals, the crypto industry is increasingly embracing closed-source development—a decision that’s sparking intense debate.
Open-source software was once a non-negotiable ethos in crypto. It allowed anyone to verify code, review vulnerabilities, and contribute improvements. But in 2025, the tide is turning.
Why Are Crypto Projects Closing Their Code?
As the competition intensifies, forked projects and copycats—from Uniswap clones to Ethereum alternatives—have pushed developers to lock their innovations behind closed doors. The motivation? Protect intellectual property, discourage exploits, and delay copycats.
This tactic, known as security through obscurity, hides vulnerabilities rather than fixing them, leaving critics concerned. “When code changes happen behind closed doors, you’re not decentralizing. You’re centralizing trust,” warned Jordan from Solana research firm Anza.
Solana’s Loopscale Breach Exposes the Flaws
The $5.8 million exploit of the closed-source Loopscale lending protocol on April 26 reignited these concerns. A hacker manipulated loan parameters to siphon funds—a vulnerability that, had the code been open, may have been caught earlier.
Despite negotiations that led to partial fund recovery, the damage to user trust and developer credibility was done.
“By keeping your code closed source, you’re just hiding back doors,” said Max Kaplan of Sol Strategies. “Audited, open-source code is the way forward.”
Solana Shifts Back to Transparency
Data from DefiLlama shows an encouraging reversal. As of April 29, 90% of the value locked in Solana’s DeFi sector is now tied to open-source protocols, up from less than half in 2021.
This shift reveals a growing industry consensus: openness breeds security, not risk.
Closed Code, Institutional Appeal
Still, not everyone agrees. As crypto firms seek bank charters and regulatory clarity, many are treating code like corporate IP. Rather than disrupting finance, they’re trying to integrate with it—and that means playing by Wall Street rules.
The question now is whether that shift will cost crypto its soul.
Lessons from the AI Industry
The crypto debate echoes similar tensions in AI. In early 2025, China’s DeepSeek unveiled a low-cost, open-source AI model—a direct challenge to Western dominance. But experts warned that without guardrails, such models can be exploited to generate malware and disinformation.
“Open source without safety checks is a national security risk,” said Matt Pearl from the Center for Strategic and International Studies.
The Case for Staying Open
Critics argue that even if most users don’t read code, one honest reviewer is enough to prevent disaster.
Mikko Ohtamaa of Trading Strategies emphasized that openness allows early detection of malicious code and suggested licensing models—like Uniswap’s v3 license—to protect proprietary elements without sacrificing transparency.
Meanwhile, Red Hat’s 2022 survey of 1,296 IT leaders revealed that most view enterprise open-source software as equally or more secure than proprietary systems.
“Transparency is the foundation of cryptography,” Ohtamaa said. “Without it, blockchains become no better than centralized databases.”
Conclusion: Code vs. Credibility
As crypto matures, it faces a fundamental dilemma: profit or principle? Developers must choose between the safety and community trust of open-source code, and the short-term protection offered by going closed.
With billions at stake and mainstream institutions circling, the soul of crypto hangs in the balance.
