According to news on January 27, Vitalik.eth tweeted that the elimination of the trust settings of the Groth16 algorithm should be accelerated, believing that individual trust settings for each application are outdated in the 2020s, and at least universal settings should be used. Ideally, no settings are required. . He emphasized that this requires significant improvements in infrastructure construction and standardization of the new SNARK algorithm, while citing Alin Tomescu's view that Groth16's trust setup is very cumbersome and requires a deep understanding of alternatives such as PLONK.
