The world of blockchain and decentralized technology continues to evolve, with thought leaders like Vitalik Buterin shaping its future through both technical innovation and philosophical insight. On June 28, the Ethereum co-founder hosted an open AMA on Twitter, engaging with the community on topics ranging from wallet architecture and digital privacy to cultural dynamics in crypto and even personal adventures. The session revealed not only his evolving views on projects like Bitcoin Cash (BCH), but also deep reflections on human coordination, technological ethics, and long-term survival risks.
This curated summary captures Vitalik’s most revealing responses—offering clarity for developers, investors, and enthusiasts alike.
Account Abstraction: A Foundational Design Choice

When asked whether he would include account abstraction if he could redesign Ethereum from scratch, Vitalik responded with a definitive yes.
“If I were building a system today, I’d build something like ERC-4337 right into the protocol.”
He outlined a simplified model:
- Each user account has a verifier that can read storage and transactions.
- A transaction first calls this verifier; if validation passes, the specified code executes.
- Nonces remain managed by Ethereum itself.
While this approach supports basic functionality, Vitalik acknowledged that aggregation—especially proof aggregation—is missing. He sees two promising paths forward:
- ERC-4337-style general-purpose bundling, or
- A more opinionated system where aggregated elements are claims—such as static calls to Ethereum’s state—verified via ZK-EVM proofs.
He leans toward the second option as more scalable and secure long-term.
Privacy remains a key interest. Though he doesn’t advocate for full Zcash-style anonymity by default, he believes tools enabling easier privacy—such as recursive SNARKs—could become foundational.
The Future of Crypto-Friendly Jurisdictions
When queried about which nations might emerge as ideal hubs for crypto residents, Vitalik expressed a preference for smaller countries over large ones. His reasoning centers on agility, adaptability, and the ability to experiment with novel governance models without bureaucratic inertia.
Countries embracing digital identity, transparent institutions, and open-source public infrastructure could become magnets for builders in the web3 space—especially those focused on public goods funding and decentralized science (DeSci).
Regenerative Finance & Public Goods Funding
Vitalik is particularly excited about advances in tracking funding provenance—the ability to trace how early contributions lead to final outcomes in public goods projects.
“Imagine being able to map the entire tree of contributions that led to a breakthrough in longevity research or climate tech.”
This kind of attribution enables fair recognition and reward mechanisms, fostering healthier incentive structures across open-source ecosystems. He’s encouraged by early progress but wants to see more work in this area—particularly around verifiable impact metrics.
Zuzalu: Successes and Open Challenges
Reflecting on Zuzalu, the experimental community in Montenegro, Vitalik called it a successful social prototype. Key assumptions were validated:
- It’s feasible to organize such an event at scale.
- People are willing to stay long-term.
- Ideas cross-pollinate effectively.
- Zero-knowledge (ZK) tech integrates well.
- A supportive health-oriented culture can thrive.
However, the biggest unresolved challenge? Balancing inclusivity with quality at scale.
His current thinking leans toward multi-layered community networks—modular social architectures that maintain cohesion without sacrificing openness. Future iterations may explore deeper integration of decentralized tools for communication and payments.
Ethereum Culture vs. Bitcoin: Avoiding the Noise Trap
Asked whether Ethereum risks mirroring Bitcoin’s culture—dominated by loud, non-technical voices—Vitalik clarified that non-technical participation isn’t the issue.
The real danger lies in the intersection of:
- Non-technical perspectives,
- Overconfidence, and
- Adversarial behavior.
“It’s not who speaks—it’s how they speak and whether they’re willing to listen.”
He emphasized vigilance against dogmatism and tribalism, urging the community to value humility, collaboration, and technical depth.
Mars, TPS, and Life Beyond Earth
If Mars had a million residents by 2050, $50K tickets, and Ethereum reached 60 million TPS, would he move?
His answer: “Depends on quality of life—and governance.”
Even interplanetary migration hinges on social design: legal frameworks, cultural norms, and digital autonomy. Technology enables escape—but civilization determines sustainability.
Bridging Ethereum and Bitcoin Communities
Despite historical divisions, Vitalik sees potential for cooperation—particularly around non-blockchain privacy tools.
Shared priorities could include:
- End-to-end encrypted messaging (without phone number requirements),
- Internet anonymity networks,
- Secure collaboration platforms,
- Privacy-respecting operating systems (e.g., GrapheneOS, Qubes),
- Open-source hardware and VR environments.
These tools benefit all cryptographers and freedom advocates—regardless of chain allegiance.
What Drains Vitalik’s Energy in Crypto?
The top frustration? Reducing crypto’s innovation to tokenization alone.
“Tokenization democratizes finance—but it’s not the whole story.”
Other pain points:
- Capital misallocation to low-value projects,
- Hypocritical “libertarians” who abandon principles when convenient,
- Unrealistic purism (e.g., “12-word seed phrases are enough for everyone”),
- And needless conflict within communities.
MPC Wallets vs. Smart Contract Wallets: A Fundamental Flaw
On a technical but critical note, Vitalik stated clearly:
“MPC-based EOA wallets have a fundamental flaw: they cannot revoke keys. Re-sharing doesn’t count—old holders can still recover access.”
This makes them inherently insecure compared to smart contract wallets, which allow:
- Key rotation,
- Social recovery,
- Spending limits,
- And programmable security policies.
For these reasons, he asserts: smart contract wallets are the only viable long-term solution.
This comment sparked debate, including a rebuttal from Bitizen’s founder suggesting Vitalik excels as a programmer but may lack product sense—a reminder that architecture debates often reflect differing priorities between theory and usability.
Personal Insights: From Language Learning to Ultra-Hiking
Beyond tech, Vitalik shared glimpses of his daily life:
- Regular apps: browser, chat tools, Duolingo (for language learning), Pleco (Chinese dictionary), and his Ethereum wallet.
- He continues donating to Ukraine—directly in ETH and other cryptocurrencies.
- His longest hike? 113 kilometers in 23 hours—a testament to endurance and mental discipline.
When asked about existential risks this century, he ranked:
- Artificial intelligence,
- Engineered pandemics,
- Nuclear war,
- AI-augmented totalitarianism.
Climate change was notably absent—implying he sees it as severe but less likely to cause human extinction than AI misuse or bioweapons.
FAQ Section
Q: Why does Vitalik prefer smart contract wallets over MPC?
A: Because MPC cannot truly revoke compromised keys—even after re-sharing, former participants may reconstruct them. Smart contract wallets enable full control upgrades and recovery logic.
Q: Has Vitalik changed his view on Bitcoin Cash?
A: While he once labeled BCH a failure due to internal conflicts, he now acknowledges cultural progress and offered goodwill to the community.
Q: What makes Zuzalu significant?
A: It proved that temporary communities can foster innovation, especially around ZK tech and health-focused living, while testing new forms of digital coordination.
Q: Does Vitalik believe small countries can lead in crypto adoption?
A: Yes—he believes smaller nations are more agile and capable of rapid experimentation with digital governance and crypto integration.
Q: Is tokenization undervalued or overvalued in crypto discourse?
A: Overemphasized. While valuable for financial access, reducing crypto’s potential to tokenization ignores broader applications in identity, governance, and privacy.
Q: How far did Vitalik actually hike?
A: 113 kilometers (about 70 miles), completed in 23 hours—an extraordinary feat of physical and mental resilience.
