On August 16th, Vitalik Buterin, co-founder of Ethereum, shared his thoughts on the fact-checking tool "Community Notes" on the X platform (formerly Twitter), stating that although the tool is not a "cryptographic project," it may be the closest thing to a "cryptographic value" seen in the mainstream world.

Vitalik stated that "Community Notes" is not written or planned by a group of selected experts, but can be written and voted on by anyone, and which notes are displayed or not is entirely determined by open source algorithms. The Twitter website provides detailed and extensive guidelines describing how the algorithm works, and users can download data containing published notes and votes, run the algorithm locally, and verify that the output matches the content visible on the Twitter website.

Vitalik said, "It is not perfect, but surprisingly, it comes close to meeting the ideal of trustworthy neutrality. At the same time, even in controversial cases, it is impressively useful."
