Industry Perspectives
On Account Abstraction
Soul Wallet's Question:
"Would you include account abstraction in Ethereum if you could revisit its design?"
Vitalik's Response:
"Yes, absolutely. A simplified version would integrate validation codes for user accounts while preserving nonce management by Ethereum. The critical challenge lies in aggregation systems—whether to adopt ERC-4337's generalized approach or a more opinionated ZK-EVM proof aggregation model."
Crypto-Friendly Jurisdictions
Eva Beylin's Question:
"Which countries show promise as long-term crypto hubs?"
Vitalik's Answer:
"Generally more optimistic about smaller nations than large powers."
Technological Debates
MPC Wallet Controversy
Yuga's Question:
"How do MPC-based EOA wallets compare to smart contract wallets?"
Vitalik's Firm Stance:
"MPC EOA wallets have fundamental flaws—they cannot revoke keys permanently. Smart contract wallets remain the only viable solution."
👉 MPC wallet proponents countered this view, citing Vitalik's potential blind spots as a product manager.
P2P Networking Priorities
Alex's Question:
"What P2P network directions merit researchers' attention?"
Vitalik's Pragmatic Focus:
"Strengthening Ethereum's existing P2P layer against censorship and firewall challenges may lack glamour but proves critical."
Personal Insights
Extreme Endurance
Cxqmaggie's Question:
"What's your farthest walking distance?"
Vitalik's Record:
"113 kilometers continuously over 23 hours."
Life Priorities
Longzhu's Hypothetical:
"Would you relocate to Mars if 1 million settlers lived there by 2050 with $50K flights?"
Vitalik's Criteria:
"Quality of life, jurisdiction models, and cultural development would determine this."
Cultural Observations
Bitcoin-Ethereum Relations
Pourteaux's Question:
"Should we foster kinship between Bitcoin and Ethereum holders?"
Vitalik's Collaboration Idea:
"Joint support for non-blockchain privacy tools—anonymous messaging, open hardware, secure OSs—represents common ground."
BCH Community Growth
Bitcoin Cash Podcast:
"Does BCH's recent stability change your previous assessment?"
Vitalik's Acknowledgement:
"Visible cultural progress! Wishing the community continued success."
