That day, I roast in the group: "It's impossible to distinguish between people and AI when chatting online." My friend threw a link to me: @Billions_ntwk - the world's first Human+AI network. At first, I thought it was the kind of "eye scanning" project, but I found out that the entire process only required a passport and phone number, without facial recognition, fingerprints, or data submission. Use zero knowledge proof to handle it directly, with full privacy. AI can also be labeled. Who are humans and who are machines? At a glance, it's clear that wool harvesting robots have no chance. Once registered, it can be used universally in all supported applications. Developers can also use this protocol to prevent witch attacks and create a cleaner Web3 world.
