The first version of @1inch Network instant governance was exactly what @VitalikButerin described as «Solution 1: limited governance». It was weighted average of stakers votes applied gradually within 24 hours to prevent any kind of front-running attacks.
Decentralized governance is necessary, but coin voting governance in its current form has many acknowledged and unacknowledged dangers. Augmenting or moving beyond coin voting is a key part of the solution: vitalik.ca/general/2021/08/1…
