Vitalik: What do I think about Community Notes

Vitalik Buterin argues that Twitter's Community Notes feature is among the closest mainstream approximations of crypto values, because anyone can write and rate notes and an open source algorithm decides which notes appear. He says the notes are informative and valuable both in his view and in that of many people across the political spectrum he talks to. The algorithm prioritizes notes rated helpful by users who usually disagree, using a "polarity" term that absorbs partisan effects and a "helpfulness" score that must reach at least +0.4 for a note to be shown. Buterin says the polarity axis emerged from the data and maps closely to left versus right, and that the full implementation is 6282 lines across 22 files.
