The evolution of blockchain technology over the past decade has been nothing short of revolutionary. At the heart of this transformation stands Vitalik Buterin—widely known as V神—the visionary co-founder of Ethereum. Recently, he took a step back to reflect on key moments, predictions, and turning points from the last 10 years. From early takes on Bitcoin and Bitcoin Cash to long-term visions for proof-of-stake and Layer 2 scaling, his insights offer a rare blend of technical depth and philosophical maturity.
This retrospective not only reveals how far the crypto space has come but also highlights the challenges still ahead.

Early Insights: Bitcoin, Censorship Resistance, and Stablecoins
In 2013, Vitalik wrote about how Bitcoin could empower people in countries like Iran and Argentina—focusing not on its fixed supply cap, but on its international reach and censorship resistance. He predicted that stable currencies would thrive in high-inflation economies.
Fast forward to today: during a recent visit to Argentina, he found his prediction largely accurate. Cryptocurrency adoption is widespread—but notably, most real-world usage revolves around stablecoins like USDT, not native cryptocurrencies. Businesses operate in digital dollars, shielding themselves from local currency instability.
However, this reliance on dollar-pegged assets introduces a new vulnerability: if the U.S. dollar itself faces systemic issues, the entire model may need rethinking. Still, the core idea holds—people seek financial tools that are both accessible and resistant to government overreach.
His second major insight from 2013 focused on regulation. He argued that Bitcoin's censorship resistance comes from its technical architecture, not legal loopholes. Today, he refines this view: while decentralization allows crypto to survive hostile regulation, it cannot flourish without public legitimacy. True resilience requires both technological robustness and social acceptance.
Proof-of-Stake and Sharding: A Journey of Patience and Simplicity
One of the most candid parts of Vitalik’s reflection involves his failed timelines for implementing proof-of-stake (PoS) and sharding—two foundational upgrades for Ethereum.
Back in 2015, he confidently predicted rapid progress. Looking back, he admits those estimates were “very wrong” and even shares an old presentation slide for others to laugh at. The core mistake? Underestimating the complexity of software development at scale.
Today, the Ethereum research community prioritizes simplicity—not just in final designs, but in the path to implementation. Complex systems are harder to secure and maintain. Dankrad’s latest sharding proposal exemplifies this shift: pragmatic, modular, and focused on achievable milestones.
Yet the original vision remains intact:
“Blockchain 1.0: every node downloads everything.”
“BitTorrent: nodes download pieces—but no consensus.”
Ideal: BitTorrent-like efficiency with blockchain-grade consensus.
This dream drives ongoing work in ZK-SNARKs, data availability sampling, and peer-to-peer networking innovations.

From Soldier Mindset to Scout Mindset: Evolving Philosophies
Vitalik traces a deep intellectual shift in his thinking—from what he calls a “soldier mindset” to a “scout mindset.”
In the early days, he supported proof-of-work (PoW) simply because it was part of the established crypto narrative. By 2013, he became excited about proof-of-stake; by 2014, he fully pivoted. This wasn’t inconsistency—it was growth.
He moved from defending ideas because he identified with them ("X must be right because I support X") to evaluating them objectively ("X has flaws; Y fixes them; therefore, X+Y is better").
This evolution mirrors broader trends in the crypto community: moving away from ideological purity toward practical solutions.
The Limits of Formal Systems and Smart Contracts
In 2014, Vitalik championed the idea of turning society into a formal, rules-based system powered by smart contracts. Over time, however, he recognized the limitations.
“Almost any formal system with more than two participants is attackable.”
While automation brings efficiency, it can't replace human judgment in complex social contexts. Governance, dispute resolution, and incentive alignment often require flexibility beyond code.
This realization shaped Ethereum’s approach to DAOs, governance mechanisms, and on-chain coordination—areas where technical design meets real-world human behavior.
Altcoins, Interoperability, and the Rise of Layer 2
Long before Ethereum existed, Vitalik was already advocating for multiple blockchains—what we now call altcoins. In a 2013 article, he made three key arguments:
- Different chains can optimize for different use cases.
- Running multiple chains has low overhead.
- Alternative chains provide checks on core developer power.
Today, he acknowledges these points have diminished relevance. Why?
- Modern blockchains are more generalized.
- Cross-chain bridges introduce significant security risks.
- Most experimentation now happens safely within Layer 2 solutions.
Still, he believes there’s room for diverse Layer 1 ecosystems—especially when they serve unique regulatory, cultural, or technical needs.
“Some things just can’t be done on L2s.”
This nuanced stance reflects a mature understanding of the ecosystem: consolidation brings efficiency, but diversity ensures resilience.
Bitcoin Cash: A Cautionary Tale of Community Dynamics
Vitalik once supported Bitcoin Cash (BCH), siding with large-block proponents during Bitcoin’s scaling debate. Today, he calls it a failure—not technically, but socially.
His key insight?
“Communities formed around rebellion often face long-term struggles because they value courage over competence.”
Such groups unite against a common enemy but lack a coherent vision for what comes next. Loyalty replaces meritocracy. Resistance becomes identity.
This lesson extends beyond BCH—it applies to forks, DAO splits, and even governance battles within Ethereum itself.
Uniswap and the Power of Simple Ideas
Long before DeFi exploded, Vitalik was quietly promoting simple protocols like Uniswap. His philosophy?
“Do something simple and dumb—even if suboptimal.”
Sometimes, minimal viable designs spark entire ecosystems. Uniswap proved that automated market makers could work at scale—paving the way for today’s $50B+ DeFi landscape.
This principle continues to influence Ethereum’s development culture: prioritize clarity, composability, and incremental progress over grand, fragile architectures.
What Ethereum Got Right—and Wrong
Looking back at the original Ethereum whitepaper, many predictions came true:
- ERC-20 tokens
- Algorithmic stablecoins
- Decentralized DNS (e.g., ENS)
- On-chain wallets with withdrawal limits
- Oracles and prediction markets
Two notable misses?
- NFTs – Entirely unforeseen in 2013.
- DAO governance collusion – The biggest unanticipated flaw in decentralized organizations.
While decentralized file storage and compute (like IPFS or TrueBit) remain underdeveloped, their foundational ideas continue to inspire new projects.
Final Reflections: Simplicity, Humility, and the Road Ahead
Vitalik concludes with humility:
- Early thinking was too focused on neat formal models—underestimating politics and human complexity.
- He avoided Bitcoin maximalism early on—a rare foresight.
- Fighting against something doesn’t guarantee success; new structures bring new problems.
- Abstract ideas? He excels there. Software execution? That required hard lessons.
- Above all: we need simpler systems than we once thought.
Frequently Asked Questions
Q: Did Vitalik predict NFTs?
A: No. Despite foreseeing many DeFi primitives, NFTs were completely absent from his early writings.
Q: Why did he change his mind on Bitcoin Cash?
A: While he agreed with their technical stance on block size, he now sees BCH as a cautionary tale about rebel-led communities struggling with long-term governance and innovation.
Q: Is Layer 2 replacing Layer 1?
A: Not entirely. L2s handle most applications today, but Vitalik believes certain use cases will always require independent Layer 1 chains.
Q: What was wrong with early DAO governance models?
A: They didn’t account for collusion—where small groups manipulate voting outcomes—leading to centralization risks despite decentralized appearances.
Q: Does he still believe in sharding?
A: Yes. Though delayed, sharding remains central to Ethereum’s long-term scalability roadmap.
Q: What’s more important—technology or social legitimacy?
A: Both. Technology enables survival under pressure; social trust enables mass adoption and sustainable growth.
