The blockchain landscape has evolved dramatically since its early days. What once began as a technical debate over decentralization, scalability, and security—the so-called "blockchain trilemma"—has now transformed into a far more complex challenge. Today’s trilemma isn’t about code or consensus algorithms; it’s about products, customers, and regulatory approval. According to Paul Brody, Global Blockchain Leader at EY, the new reality for digital asset builders is simple: pick any two.
From Technical Trade-Offs to Market Realities
In the early years of blockchain development, the prevailing belief was that systems could only achieve two out of three core attributes: decentralization, scalability, and security. Ethereum, for example, long stood as a model of decentralization and security—but at the cost of scalability. Transactions were slow and expensive during peak usage, limiting real-world adoption.
That began to change with Ethereum’s transition from Proof of Work (PoW) to Proof of Stake (PoS) and the rapid rise of layer 2 scaling solutions like Optimism and Arbitrum. These innovations have significantly improved transaction throughput while maintaining the foundational security and decentralization of the base chain. As a result, most users now consider blockchain performance “good enough” across all three technical dimensions.
But as the technology matures, the bottleneck has shifted—from infrastructure to market dynamics. The new trilemma reflects this evolution: products, customers, and regulatory approval. And just like before, achieving all three simultaneously remains elusive.
The Three Sides of the New Trilemma
1. Crypto-Native Firms: Products + Customers, No Approval
Many leading crypto-native companies have built robust platforms with diverse digital asset offerings and active user bases. Exchanges, DeFi protocols, and wallet providers serve millions globally—most of whom operate in unregulated or offshore environments.
However, despite their scale and innovation, these firms often lack formal regulatory licenses in major financial markets like the U.S., EU, or Japan. During recent market downturns, many scaled back compliance efforts, prioritizing survival over licensing. Now, as regulation tightens, they find themselves unable to onboard institutional clients or expand into mainstream finance without approvals.

2. Regulated Digital Asset Startups: Products + Approval, No Customers
On the flip side are startups that launched within regulated frameworks—issuing tokenized funds, securities, or stablecoins under strict oversight. These firms have navigated complex approval processes and secured green lights from regulators such as the SEC or ESMA.
Yet despite their legitimacy, they struggle to attract users. Without an existing customer base or brand recognition, their products sit underutilized. Unlike traditional banks or fintech giants, they lack distribution channels and trust among retail investors.
This group exemplifies a critical lesson: regulatory approval doesn’t guarantee market adoption.
3. Traditional Financial Institutions: Customers + Compliance, No Products
Then there are the world’s largest banks and asset managers. They possess vast customer networks, deep trust, and decades of regulatory compliance experience. But when it comes to digital assets, most have been slow to act.
While some have launched tokenized fund pilots or custody services, few offer compelling crypto-native products. Their risk-averse cultures and legacy systems make rapid innovation difficult. As a result, they sit on one side of the trilemma—rich in customers and compliance—but poor in product innovation.
Why Can’t All Three Align?
So why can’t these groups simply merge? Why isn’t there a single entity offering approved products to a global customer base?
Two major obstacles stand in the way.
1. Regulatory Guardrails Are by Design
Regulators aren’t blocking progress—they’re managing risk. In conversations with global authorities, a consistent message emerges: not all digital assets are suitable for all investors.
Crypto markets are volatile. Products like leveraged tokens, algorithmic stablecoins, or high-yield DeFi staking may be appropriate for sophisticated traders—but not for retirees or low-income households. Regulators aim to create tiered access: safe on-ramps for average users, and more advanced options for accredited investors.
This intentional segmentation prevents mass-market exposure to excessive risk—but also limits the possibility of a single platform serving everyone.
2. Cultural Mismatches Run Deep
Beyond regulation lies culture. The ethos of crypto-native builders—decentralized, permissionless, anti-establishment—is fundamentally at odds with the hierarchical, compliance-driven world of traditional finance.
These aren’t just different business models—they’re different mindsets. A founder who launched a DeFi protocol during a bear market likely values speed and autonomy over process and oversight. Asking them to integrate into a bank’s governance structure is like asking a startup hacker to wear a suit every day.
Conversely, bank executives prioritize stability and audit trails over rapid experimentation. Bridging this gap requires more than partnerships—it demands cultural translation.
The Path Forward: “Good Enough” for Everyone
Just as blockchain technology reached a point where decentralization, scalability, and security became “good enough,” so too will the market evolve toward balanced solutions.
We’re already seeing convergence:
- Hybrid models where regulated institutions partner with crypto-native firms to offer compliant products.
- Custody solutions enabling banks to securely hold digital assets.
- Tokenized real-world assets (RWA) bringing traditional finance on-chain with regulatory clarity.

The future won’t belong to one dominant player offering everything. Instead, it will be a mosaic of specialized ecosystems—each serving distinct segments with tailored offerings.
Risk-tolerant investors will find advanced tools within regulated environments. Mainstream users will access simplified, vetted experiences through trusted financial brands. And innovators will continue pushing boundaries in sandboxed regulatory zones.
FAQ: Understanding the New Blockchain Trilemma
Q: What is the original blockchain trilemma?
A: The original trilemma refers to the challenge of achieving decentralization, scalability, and security simultaneously in blockchain systems—typically requiring trade-offs between two of the three.
Q: How has Ethereum addressed the technical trilemma?
A: Through its shift to Proof of Stake (PoS) and the proliferation of layer 2 networks, Ethereum has improved scalability while preserving decentralization and security on the base layer.
Q: Why can’t crypto firms easily get regulatory approval?
A: Regulatory processes are lengthy and require stringent compliance measures around AML/KYC, consumer protection, and financial reporting—areas many crypto-native firms historically deprioritized.
Q: Can traditional banks successfully launch crypto products?
A: Yes—but they often struggle with speed and user experience. Success depends on collaboration with agile tech partners who understand both blockchain and compliance.
Q: What role do ETFs play in this new trilemma?
A: The approval of Bitcoin and Ethereum ETFs in the U.S., along with MiCA in Europe, signals growing regulatory acceptance—enabling mainstream investors to access crypto through familiar, approved vehicles.
Q: Is full alignment of products, customers, and regulation possible?
A: Not perfectly—but through partnerships and layered ecosystems, the market is moving toward integrated solutions that are “good enough” for most users.

Final Thoughts
The new blockchain trilemma marks a pivotal shift—from technical constraints to market realities. As digital assets mature, success will no longer be defined by engineering prowess alone, but by the ability to navigate regulation, attract users, and deliver valuable products.
The winners won’t be those who solve all three at once—but those who strategically balance two while innovating toward the third.
