The blockchain revolution isn't just about digital money — it's a fundamental shift in how we organize society, conduct business, and trust one another. As one of the early pioneers in the space, I first encountered Bitcoin in 2012 while pursuing a Ph.D. at the Chinese Academy of Sciences. My research on peer-to-peer multimedia transmission led me to explore decentralized networks, and eventually, to the groundbreaking architecture of Bitcoin. What started as academic curiosity quickly evolved into a life-changing realization: blockchain technology was opening the door to an entirely new world.
This article explores the evolution of blockchain, its core innovations, and how it could reshape everything from finance to organizational structures — possibly even rendering traditional companies obsolete within the next three decades.
The Birth of a Revolution: Bitcoin’s 0-to-1 Breakthrough
Bitcoin wasn’t merely an upgrade — it was a paradigm shift. Before Bitcoin, distributed systems relied on centralized oversight or trusted intermediaries. But Satoshi Nakamoto introduced something unprecedented: a trustless, incentive-driven consensus mechanism powered by proof-of-work.
"Bitcoin completed the leap from horse-drawn carriage to automobile — like the invention of the steam engine."
Unlike traditional distributed networks where node failures are accidental, Bitcoin operates in an environment of intentional malicious behavior. Satoshi solved this by aligning economic incentives with network integrity. Miners compete to validate transactions using computational power — a resource that cannot be monopolized easily — ensuring fair and decentralized control over the ledger.
After six confirmations, the probability of a successful attack becomes negligible. This time-based consistency model replaced moment-to-moment agreement with probabilistic finality — a radical yet effective solution.
Today, Bitcoin functions as the world’s most robust decentralized settlement network, with over 13,000 full nodes globally (though exact numbers are hard to pin down due to P2P dynamics). Each full node operator holds equal power — no need to trust banks, payment processors, or third parties.

Compared to centralized systems like Alipay or traditional banking, Bitcoin’s service boundary is limitless. Anyone with a computer can run a node and participate — no permission required. While Alipay serves the RMB ecosystem, Bitcoin is both the network and the currency.
Its brand strength and network effect are unmatched. And though many altcoins have emerged, most are iterative improvements — moving from 1 to 1.001 — built upon Bitcoin’s foundational breakthrough.
Beyond Currency: The Evolution of Blockchain
When I first entered the space in 2012, there was no “crypto community” per se — just tech enthusiasts discussing mining and transactions. The term blockchain didn’t gain traction until around 2015, when developers began separating the underlying technology from its monetary use case to better communicate its potential under existing legal frameworks.
Since then, the industry has grown into a full-fledged ecosystem — peaking at $800 billion in market cap and currently stabilizing around $300 billion. This journey has been marked by cycles of innovation, speculation, and consolidation.
Bitcoin proved the security and reliability of large-scale peer-to-peer networks. However, its scripting language is limited — unsuitable for complex applications. Enter Ethereum, which introduced the Ethereum Virtual Machine (EVM) and smart contracts, enabling programmable logic on-chain.
Smart contracts automate business processes — think of them as digital agents that execute agreements without human intervention. For example, real estate giant Lianjia employs tens of thousands of agents for repetitive contract work. With smart contracts, thousands of agreements could be processed instantly across a few computers — reducing cost, error, and inefficiency.
Yet despite the ICO boom proving smart contracts’ utility in fundraising, most projects lacked sustainable business models. The real challenge now is finding use cases beyond speculation — applications that deliver tangible value.
Key Areas for Future Adoption:
- Gaming: Ownership of digital assets (e.g., NFTs) can transform in-game economies.
- Digital Content: Creators can monetize music, videos, and art directly via unique IDs.
- Identity Management: Human, machine, and object identities can be securely recorded on-chain.
- Finance: Decentralized insurance, lending, and investment platforms enable self-sovereign finance.
- Organizational Design: Could companies become obsolete?

Why I Founded Qtum: Bridging Two Worlds
Bitcoin excels as digital gold — secure, scarce, and decentralized. Ethereum enables powerful computation through smart contracts. But what if we could combine both?
In 2015, while working on a supply chain startup using Ethereum, I noticed its limitations — scalability issues, governance challenges, and high developer barriers. At the same time, Bitcoin maximalists dismissed Ethereum as a scam, while Ethereum supporters mocked Bitcoin’s lack of functionality.
I saw an opportunity: build a bridge.
Thus, Qtum (Quantum Chain) was born — a platform designed to bring smart contract capabilities to Bitcoin’s rock-solid UTXO model.
Qtum’s Core Innovations:
- Security Through Proven Code: Built on Bitcoin’s battle-tested codebase with contributions from over 400 developers.
- Flexibility via Account Abstraction Layer (AAL): Supports multiple virtual machines including EVM and our own X86 VM, enabling developers to write smart contracts in C++, Rust, and other mainstream languages.
- Decentralized Consensus (PoS): Anyone can run a full node; no staking minimums. Currently supports ~2,000 nodes across 87 countries — aiming for 50,000+.
- Scalability Without Sacrificing Decentralization: ~70 TPS (vs. Bitcoin’s 3–7), capable of handling 3 million transactions daily theoretically.
- On-Chain Governance (DGP): Network upgrades happen seamlessly without hard forks — e.g., adjusting gas fees dynamically.
- Thriving DApp Ecosystem: Over 30 DApps launched within three months of mainnet release — second only to Ethereum at the time.
- UTXO-Based PoS Smart Contracts: First blockchain to implement this hybrid approach — combining security with programmability.
Qtum isn’t about reinventing the wheel — it’s about building on proven foundations while pushing boundaries.
Where Will Blockchain Be Applied First?
While blockchain won’t replace apps for food delivery or ride-hailing anytime soon — areas dominated by giants like BAT — it shines in niche domains where trust, ownership, and automation matter.
Most Promising Use Cases:
- Digital Asset Ownership (e.g., gaming items)
- Content Monetization (e.g., music royalties)
- Identity Verification (self-sovereign ID)
- Financial Inclusion (DeFi, micro-insurance)
- Autonomous Organizations (DAOs replacing traditional firms)
Eventually, blockchain could become the global computer — where instead of downloading apps from an App Store, users interact with protocols directly via voice or AI assistants.
Imagine saying “Call me a ride,” and your device automatically triggers a smart contract that matches you with a driver and settles payment on-chain — all without intermediaries.
The Essence of Public Blockchains: Decentralization Above All
Public blockchains must prioritize decentralization over raw speed or scalability. Projects like EOS or Ripple achieve high TPS by limiting node participation — effectively recreating centralized systems.
In contrast:
- Bitcoin focuses on being digital cash — secure, stable, but rigid.
- Ethereum is a global state machine enabling complex logic via smart contracts.
- Qtum merges Bitcoin’s security with Ethereum-like flexibility through layered design.
True decentralization means every participant can run a full node and verify the entire chain independently. This shifts power from institutions (banks, Visa) back to individuals — creating information symmetry instead of asymmetry.
Yes, higher TPS sounds appealing — but not at the cost of censorship resistance and user sovereignty.
A World Without Companies?
It sounds radical: “In 30 years, all companies might disappear.” Yet consider this — the modern corporation is only about 300 years old. In the grand timeline of human history, it’s a blip.
Blockchain enables new forms of coordination — what I call Protocol-Based Commonwealths (PBCs) or decentralized autonomous organizations (DAOs). These are self-governing entities running on code rather than hierarchies.
Bitcoin itself is proof: a $150B+ network with no CEO, no boardroom, no headquarters — just rules enforced by consensus.
As more services move onto open protocols, we may see a future where individuals collaborate freely through smart contracts — without needing corporate structures.
This transformation won’t happen overnight. But just as no one predicted Uber in 2000, we can’t fully grasp what blockchain will enable in 2035 or 2045.
