It's not exactly democracy once you add weights penalising erroneous information and bad actors. Science kind of works this way, you have papers to support, and lack of rebuttal is sort of understood as general acceptance, new evidence updates our beliefs about old information. I think it should be feasible to encode this general agreement into something that can be put into a database. No one has succeeded I guess, and it seems a bit harder since "flatearther-12345" is initially the same as "actual_scientist" since it's hard to have verified identity and offer anonymity at the same time.
