In a recent public AMA on Twitter, Ethereum co-founder Vitalik Buterin shared candid insights on blockchain evolution, community culture, wallet security, and long-term technological risks. The wide-ranging discussion revealed not only his technical depth but also his evolving perspective on decentralized ecosystems, digital privacy, and the future of human coordination.
Covering topics from account abstraction to Mars colonization, Vitalik’s responses reflect a forward-thinking vision grounded in pragmatism and ethical responsibility. Below is a refined, SEO-optimized summary of key takeaways—structured for clarity, enriched with core keywords, and enhanced with natural reader engagement points.
The Case for Smart Contract Wallets Over MPC-Based EOA
One of the most debated responses addressed the limitations of Multi-Party Computation (MPC)-based Externally Owned Accounts (EOAs). Vitalik stated clearly:
“MPC-based EOA wallets have fundamental flaws because they cannot revoke keys—re-sharing doesn’t count; old holders can still recover access.”
According to him, smart contract wallets are the only viable path forward. These wallets offer advanced features like social recovery, transaction batching, and gas sponsorship—capabilities essential for mainstream adoption.
While some in the MPC community pushed back—such as Bitizen’s founder, who called Vitalik a brilliant coder but questioned his product sense—the argument underscores a growing industry shift toward account abstraction, particularly via standards like ERC-4337.

This isn’t just about convenience—it’s about building resilient identity layers for Web3 that prioritize user sovereignty over infrastructure rigidity.
Zuzalu: A Decentralized Social Experiment That Worked
When asked whether Zuzalu lived up to expectations, Vitalik responded positively, calling it a successful experiment that validated several core assumptions:
- Large-scale decentralized events can be organized effectively.
- People are willing to stay and engage long-term.
- Ideas cross-pollinate across disciplines.
- Zero-knowledge (ZK) technologies integrate smoothly into real-world use cases.
- Healthy, collaborative cultures can emerge organically.
Zuzalu demonstrated that temporary autonomous zones—physical or digital—can foster innovation in privacy-preserving tech, public goods funding, and decentralized governance.
However, one major challenge remains: balancing inclusivity with quality at scale. Vitalik hinted at a multi-layered “community network” model as a potential solution—one where trust and contribution determine access levels without sacrificing openness.
Future iterations may focus on deeper integration of privacy-friendly tools, such as decentralized identity systems (like Zupass), censorship-resistant communication platforms (e.g., Skiff or Status), and Layer 2 payments using ETH.
On BCH: Cultural Growth Matters
Reflecting on Bitcoin Cash (BCH), Vitalik acknowledged past criticism—particularly around internal conflicts and centralization tendencies—but noted visible cultural progress in recent years.
“Visible cultural progress! Wishing you all the best.”
This subtle endorsement suggests that while technical design is crucial, community health and ideological maturity play equally important roles in a blockchain’s longevity. For projects aiming for sustainable growth, fostering constructive dialogue and minimizing tribalism may matter more than short-term metrics.
It also highlights a broader trend: the crypto space is maturing beyond dogma. Even rival ecosystems are beginning to earn recognition for resilience and evolution.
Why Tokenization Isn’t the Only Breakthrough
Vitalik expressed frustration with those who view tokenization as the primary innovation of blockchain technology.
“People thinking tokenization is crypto’s main breakthrough… it consumes too much of my mental energy.”
While he acknowledges tokenization enables new economic models and democratizes financial access, he warns against reducing crypto’s potential to mere asset digitization.
Instead, he champions underappreciated innovations:
- End-to-end encrypted messaging (without phone number reliance)
- Network anonymity tools
- Open-source hardware and operating systems (e.g., GrapheneOS, Qubes OS)
- Secure collaboration platforms
- Privacy-preserving virtual reality
These tools form the foundation of a truly free and private digital society—one where decentralization extends beyond money to communication, identity, and expression.
Ethereum's Future: Native Privacy and Scalability
Looking ahead, Vitalik shared thoughts on improving Ethereum from the ground up—if he were to redesign it today.
He emphasized integrating account abstraction natively, possibly through a simplified version of ERC-4337, where each account has a “validation code” that checks transactions before execution. Nonces would remain managed by the protocol for simplicity.
Two paths stand out for scaling verification:
- Generalized aggregation systems (like ERC-4337).
- Claim-based aggregation using ZK-EVMs to prove statements about Ethereum’s state.
He leans toward the second approach as more promising long-term.
Additionally, he expressed interest in making privacy more native to blockchain design—not full Zcash-style anonymity, but accessible privacy tools powered by recursive SNARKs and zero-knowledge proofs.
FAQs: Addressing Common Questions
Q: Why does Vitalik prefer smart contract wallets?
A: Because they support key revocation, social recovery, batched transactions, and gas abstraction—features impossible with traditional EOA or MPC wallets.
Q: What made Zuzalu successful?
A: It proved that decentralized communities can self-organize, sustain engagement, share ideas across domains, and adopt advanced tech like ZK-proofs in real-world settings.
Q: Is Vitalik against tokenization?
A: No—he recognizes its value—but believes focusing solely on tokenization overlooks deeper opportunities in privacy, governance, and digital rights.
Q: Could Ethereum become too centralized like Bitcoin?
A: Vitalik warns against non-technical, overconfident, and adversarial voices dominating discourse. He stresses maintaining technical rigor and collaborative culture.
Q: What are the biggest existential threats this century?
A: Top concerns include unaligned artificial intelligence, engineered pandemics, nuclear war, and AI-enhanced authoritarian regimes.
Q: Would Vitalik move to Mars?
A: It depends on quality of life, governance structure, and cultural environment—not just ticket prices or population size.
P2P Networks and the Unsexy Work Ahead
When asked about promising research areas in Ethereum’s peer-to-peer network layer, Vitalik pointed to an often-overlooked domain: strengthening resilience against censorship and firewalls.
“Not sexy, but critically important.”
As governments increase surveillance and network interference, robust p2p protocols become essential for maintaining decentralization. Researchers are encouraged to explore redundancy mechanisms, peer discovery under duress, and obfuscation techniques that preserve node connectivity without compromising speed or efficiency.
Final Thoughts: Beyond Technology
Vitalik’s AMA reveals a thinker deeply invested not just in code, but in human coordination, ethical design, and long-term survival. His critiques of tribalism, capital misallocation, and ideological purity tests speak to a desire for maturity within the crypto space.
Whether discussing Mars colonies or mental health in tech communities, his vision remains consistent: build systems that empower individuals while safeguarding collective well-being.
