Vitalik Buterin Advocates Decentralization and Highlights Risks

The Risks of Centralization

Vitalik Buterin, co-founder of Ethereum, has expressed concerns about centralized systems, labeling them as inherently problematic. He emphasized the benefits of decentralized finance (DeFi) and self-custody, while acknowledging that these systems are not without risks. Key vulnerabilities include bugs in smart contract code, which require vigilance and robust protective measures.

Safeguarding Blockchain Systems

Buterin outlined strategies to mitigate risks associated with blockchain technology. He stressed the importance of keeping code simple and encouraged practices like audits and formal verification to enhance security. These steps are crucial for maintaining the integrity of smart contracts, especially those running on the Ethereum Virtual Machine (EVM).

Concerns Over ZK-Rollup

Buterin voiced specific worries regarding ZK-rollup, a layer-2 blockchain protocol that processes transactions off-chain while holding assets in an on-chain smart contract. He highlighted the potential danger of having significant financial assets in such systems, which could be compromised by bugs in the circuit constraint code or EVM wrapper.

Strategies for Protection

To protect against such vulnerabilities, Buterin suggested hardening the roll-ups with multi-proofs. Despite acknowledging that ZK-EVMs may not be bug-free soon, he believes that the risk of catastrophic failures can be minimized through multiple implementations and careful management.

Balancing Security and Governance

Buterin also discussed the trade-off between security against bugs and security against poor governance. He proposed that governance should be involved in blockchain systems but only in emergencies, to balance safety with operational efficiency. This approach aims to enhance the resilience and reliability of decentralized technologies.
