Ethereum co-founder Vitalik Buterin stated that an important but long-underestimated form of "trustlessness" is enabling as many people as possible to truly understand how the entire protocol works from start to finish. If only a very small number of people possess a complete understanding, the system still carries the implicit risk of centralized trust. Vitalik pointed out that Ethereum still has room for improvement in this regard, and future efforts should focus on simplifying protocol design and reducing system complexity to enhance overall understandability. This will not only help expand the pool of people who can participate in and audit the protocol but will also enhance the transparency, security, and long-term resilience of the Ethereum ecosystem.
