[Vitalik: Enhancing trustlessness lies in enabling more people to fully understand the protocol; Ethereum needs simplification] Foresight News reports that Vitalik Buterin tweeted, 'An important and underrated form of trustlessness is increasing the number of people who can fully understand the entire protocol from start to finish. Ethereum needs to improve on this (by simplifying the protocol).' A user then asked, 'But at this scale, how simple can it realistically be? People always feel there’s a trade-off between functionality and understanding.' Vitalik Buterin responded, 'Sometimes we should be willing to reduce functionality.'
