Questions & Answers

Q: What is the main focus for Ethereum's future development?

Buterin emphasizes scaling privacy and security as the key areas for Ethereum's long-term development.

Q: How does Buterin respond to criticisms that proof-of-stake centralizes influence?

Buterin argues that proof-of-stake is not more centralized than proof-of-work, and provides examples of concentrated mining power in Bitcoin as evidence.

Q: How is Ethereum improving smart contract security?

Buterin discusses the development of languages like Viper and stricter checks in the Solidity programming language to make writing smart contracts safer. He also mentions the importance of good code samples and templates.

Q: What is the future of funds lost in the Parity multi-sig bug?

Buterin suggests that the funds can only be recovered through a hard fork or the creation of a new blockchain, but acknowledges the challenges in implementing them due to community consensus.

Q: What is Buterin's role in Ethereum and how does he see the community evolving?

Buterin sees himself as a chief scientist and emphasizes the importance of decentralization and inclusivity within the Ethereum community.

Q: What is the potential of privacy-preserving technologies in Ethereum, such as zero-knowledge proofs?

Buterin sees applications in gaming and virtual collectibles, and highlights the benefits of an open ecosystem for trading and interacting with privacy-preserving tokens.

Q: Are private or consortium blockchains valuable?

Buterin expresses skepticism towards private or consortium blockchains, stating that they often struggle to achieve decentralization and lack the benefits of a public blockchain.

Summary

This video features an interview with Vitalik Buterin, the co-founder of Ethereum. He discusses various topics including scaling, privacy, security, programming languages, smart contract vulnerabilities, decentralized exchanges, tokenization of real-world assets, and the differences between Ethereum and Bitcoin communities. Buterin shares his insights on these subjects and provides explanations and examples to support his views.

Questions & Answers

Q: What are some criticisms of proof of stake and how does it compare to proof of work?

Buterin discusses one of the criticisms that suggest proof of stake makes the rich get richer and centralizes influence. He argues that this criticism is invalid. He explains that proof of work is also centralized to some extent, with a few big players controlling a significant percentage of the hashing power. In contrast, proof of stake can provide a substantial improvement by reducing the rich get richer effect, compared to proof of work.

Q: How is Ethereum improving smart contract security?

Buterin explains that Ethereum is focusing on developing better programming languages and standards to enhance smart contract security. He mentions the introduction of Viper, a language designed to be more secure and harder to write misleading code. Additionally, improvements have been made to Solidity, the existing language for Ethereum smart contracts, such as safe math libraries and stricter checks. Buterin also highlights the importance of having good code samples and templates to make it easier to write secure contracts.

Q: What is the current status of the funds lost in the Parity multi-sig bug?

The funds can only be moved if the Ethereum community agrees on a hard fork to modify the contract code or move the money elsewhere for recovery. Buterin acknowledges the mathematical possibility of recovering the funds through a hard fork, but deems the chances low due to the current lack of political will. Another possibility is a new blockchain being created that incorporates the modifications needed to recover the funds. But ultimately, the decision lies with the Ethereum community, and their discussions and opinions will influence the outcome.

Q: How do you see your role in the Ethereum community as both a public face and chief scientist?

Buterin points out that he has already stepped back from the administrative side of the Ethereum Foundation, with the executive director overseeing those responsibilities. He mentions the work of other team leaders and managers within the Ethereum ecosystem, highlighting the decentralized nature of the community. Buterin emphasizes the importance of not having strict divisions between insiders and outsiders and the inclusion of diverse contributors. He also acknowledges the need for continuous growth with more people working on research and development.

Q: How is Ethereum addressing privacy concerns?

Buterin discusses Ethereum's efforts to improve privacy by incorporating zero-knowledge proofs and other cryptographic techniques. He mentions the release of Byzantium, an Ethereum update that includes zero-knowledge primitive operations. Ethereum is also supporting the development of zero-knowledge proof technologies like snarks and Starks. Buterin explains that research is ongoing to further optimize these privacy-preserving schemes and create better programming abstractions for privacy on top of the Ethereum blockchain.

Q: Is there concern that privacy-preserving technologies on Ethereum may attract regulatory attention?

Buterin states that he expects some regulatory responses aimed at blockchains. However, he believes it will be challenging for regulators to target blockchains directly due to the decentralized nature of the technology. He points out that there are legitimate uses for privacy technologies beyond criminal activities and emphasizes the importance of highlighting their benefits in scalability and improved mechanisms.

Q: What is your perspective on tokenization of real-world assets and security tokens?

Buterin sees value in tokenizing real-world assets and highlights the advantages of an open ecosystem for trading and utilizing these tokens. He believes that innovation can arise from the interaction of various projects within this ecosystem. However, he expresses skepticism about tokenizing art, acknowledging that it may not be psychologically easy for people to adapt from traditional art purchases to digital representations. Buterin mentions the need for advancements in user authentication technologies to ensure secure and user-friendly experiences with tokenized assets.

Q: What is the future of decentralized exchanges compared to centralized exchanges?

Buterin expresses his hope for centralized exchanges to be less prominent, highlighting the advantages of decentralized exchanges. He explains that decentralized exchanges offer better openness and transparency, reducing the power and control of centralized exchanges. However, he recognizes that scalability and adoption of decentralized exchanges by large-scale traders remain uncertain. Buterin concludes that progress in decentralized exchanges is positive and contributes to creating a fairer and more accessible trading environment.

Q: Why is there less strife and conflict in the Ethereum community compared to the Bitcoin community?

Buterin attributes the harmony in the Ethereum community to a combination of factors. He mentions agreeing on a social contract regarding the evolution of Ethereum, where everyone believes in ongoing development, scalability, and the adoption of proof of stake and sharding. He also credits the influence of early community members, who valued inclusivity, intellectual diversity, and technological progress. Buterin acknowledges that disagreements exist but notes that participants share a vision of improving existing systems, which aligns their goals.

Q: Where do you see a place for private or consortium blockchains?

Buterin's optimism about private or consortium blockchains has diminished since their initial hype. He points out that many pilot projects failed to become credibly decentralized and ended up controlled by a single company, undermining their purpose. He believes that compromises between decentralization and centralized efficiency can be achieved without resorting to consortium chains. Buterin mentions that Plasma chains, even if they act as centralized servers, can provide a better compromise. He concludes that there are alternative solutions that allow for the benefits of transparency and openness without sacrificing security or efficiency.
