Quantum-resistant architecture, scalable smart contracts, and a bridge between Bitcoin and Ethereum—these are the cornerstones of Qtum, a public blockchain platform founded by Daley Chou (also known as Shuai Chu), a computer scientist turned blockchain pioneer. At just 28, he was named to the 2017 Forbes 30 Under 30 list for his contributions to technology and innovation. As co-founder and CTO of BitSE and the mastermind behind Qtum, Daley Chou has emerged as one of the most influential voices in the blockchain space.
This article dives into his philosophy on blockchain’s evolution, the technical vision behind Qtum, and where decentralized technology might lead us in the next decade.
The Long Game: Blockchain Enters the Marathon Phase
Daley Chou has long advocated for a sober, long-term perspective on blockchain development. In a widely shared reflection, he outlined what he calls the "cold thoughts" about the industry’s trajectory—insights that remain highly relevant today.

He believes the initial hype cycle is fading, and the industry is transitioning into a marathon phase—a period defined not by grand promises but by execution, sustainability, and real-world utility.
Here are his key observations:
- History repeats itself, depending on your time horizon—whether you're looking at one year or a decade.
- The market is shifting from idea-driven projects to product-first innovation. Many teams lack the operational experience to survive this shift.
- Projects with unrealistic roadmaps or no clear use cases will burn through capital and fail.
- Regulatory actions and high-profile scandals will accelerate industry consolidation.
- Profitable companies will emerge in both B2B and B2C sectors, entering sustainable growth cycles.
- Foundations will evolve into hybrid models combining nonprofit and corporate structures. Tokens may begin offering dividend-like returns, functioning similarly to equity.
- Project teams will prioritize monetization strategies, with revenue coming from investments, donations, core services, and ecosystem fees.
- Speculative concepts will be debunked, educating investors and media alike, leading to more cautious evaluations of new ventures.
- Only those solving real-world problems or creating new demand will thrive—and potentially gain regulatory approval within 5–7 years.
- The race has just begun: focus on technology, product design, cost efficiency, profitability, and long-term vision.
In essence, Chou urges builders to think in 5- to 10-year timelines, prioritize real solutions over buzzwords, and prepare for sustained effort rather than short sprints.
From Idealism to Innovation: A Founder's Journey
In a 2018 interview at Blockchain Connect Conference in San Francisco, Daley Chou reflected on his path from academic researcher to blockchain entrepreneur.
Back in 2012, when he first entered the space, blockchain was still a niche interest. Meetups in Shanghai drew only around 20 people. Most discussions revolved around mining and trading Bitcoin—the term “blockchain” hadn’t even gained traction yet.
Yet what struck him most was the idealism shared by early adopters—both developers and enthusiasts alike. Unlike today’s speculative frenzy, the community then was driven by curiosity and belief in decentralization.
With a PhD in computer science, Chou studied Bitcoin’s codebase deeply and saw its transformative potential. While many dismissed it as a scam, he recognized it as a once-in-a-generation technological wave.
His journey from theory to practice wasn’t smooth. Building Qtum involved years of trial, error, and refinement. He emphasizes that aspiring blockchain developers must go beyond surface-level programming.
“If you want to be a top-tier blockchain developer—not just someone building apps—you need deep knowledge in algorithms, cryptography, and system design.”
He advises newcomers to pick a specialization: scalability (e.g., higher TPS), privacy (using advanced cryptographic techniques), or industrial-grade applications like secure wallets or IoT integration.
Bridging Two Worlds: Why Qtum Combines Bitcoin and Ethereum
One of Qtum’s defining features is its hybrid architecture—merging Bitcoin’s proven security model with Ethereum’s smart contract functionality.
Bitcoin vs Ethereum: Strengths and Limitations
- Bitcoin excels as a decentralized digital currency and global settlement layer. Its UTXO model and proof-of-work consensus offer unmatched security and decentralization. However, its scripting language is limited—unsuitable for complex applications.
- Ethereum, with its EVM (Ethereum Virtual Machine) and Turing-complete smart contracts, enables sophisticated decentralized applications (dApps). But it faces challenges in scalability and governance.
Qtum’s mission? To bring smart contract capabilities to a Bitcoin-like foundation.
By layering an Ethereum-compatible virtual machine on top of a UTXO-based proof-of-stake blockchain, Qtum creates a flexible yet secure environment for dApp development.
“It’s about injecting programmability into a robust monetary protocol,” Chou explains. “We’re building a value transmission protocol and a distributed application platform.”
This dual-layer approach allows Qtum to support mobile-first applications—a strategic move aimed at improving accessibility and usability for mainstream users.
Can Blockchain Exist Without Tokens?
A common debate in the ecosystem: do all blockchains need native tokens?
Chou argues that in public blockchains, an internal cryptocurrency is essential—not just for incentives but also for network security.
Without a native token:
- There's no mechanism to reward node operators.
- The network becomes vulnerable to spam attacks (e.g., DDoS), since there’s no cost to making transactions.
For example:
- Bitcoin acts as both currency and access control—mining difficulty creates a barrier to entry.
- Ether functions as “fuel” (gas) for executing smart contracts.
In Qtum, QTUM coin serves two roles:
- As a store of value and medium of exchange (like Bitcoin).
- As gas for running dApps (like Ether).
He also distinguishes between cryptocurrencies and crypto shares. A token issued by a mooncake company for pre-orders isn’t truly a cryptocurrency—it’s more akin to a voucher or security. Regulators tend to target such instruments when they mimic traditional financial products without compliance.
What’s the Killer App for Blockchain?
Many ask: what will be blockchain’s “killer app,” like email for the internet?
Chou’s answer is bold: Bitcoin itself is already the killer app.
It created a decentralized global payment and settlement system—something previously only nation-states could achieve. That alone represents a historic breakthrough.
Looking ahead, he envisions blockchain becoming invisible infrastructure—like electricity or water—providing trust-as-a-service for every digital interaction.
Imagine saying, “Call me a car,” and your device automatically connects to a decentralized ride-hailing service via blockchain. No app stores. No intermediaries. Just instant, secure execution through smart contracts.
Developers won’t build for iOS or Android alone—they’ll deploy logic directly onto global blockchains like Qtum or Ethereum.
“Users don’t want apps—they want functions. And blockchain can deliver those functions universally.”
Decentralization vs Scalability vs Security: Can We Have All Three?
The so-called “blockchain trilemma” suggests you can only optimize two of these three properties at once.
Chou prioritizes decentralization as the core value of public blockchains.
“If you sacrifice decentralization for scalability,” he warns, “your real competitors become PayPal or Chase Bank—not other blockchains.”
Qtum uses a modified proof-of-stake consensus (Qtum's PoS) designed so that anyone can run a full node with minimal hardware. This ensures information symmetry—unlike traditional finance, where banks control data access.
While absolute finality (security) is compromised—similar to Bitcoin, which allows possible reorgs—this trade-off enables greater decentralization and throughput.
For enterprise platforms, scalability is non-negotiable. But for currency layers like Bitcoin? Longevity comes from trust, not speed.
