At the Ethereum Community Conference held in France, Vitalik Buterin stated that Ethereum is at a critical turning point, and if decentralization only stays at the slogan level, it may become an empty promise and ultimately be eliminated by the times. He proposed three testing criteria: one is the "walk away test", which refers to whether users can still control assets after the disappearance of the project party; The second is the 'insider attack test', which measures the potential damage caused by internal personnel's misconduct or front-end attacks; The third is the 'trusted computing base', which refers to the minimum amount of code required to ensure the security of user funds and data. （CoinDesk） https://www.
