Worldcoin launches proof-of-personhood
Worldcoin, co-founded by Sam Altman, launched on July 24, 2023 with the stated goal of creating a proof-of-personhood network — a cryptographic guarantee that a given voter, user, or participant is a unique human being without revealing their identity. The mechanism involves iris scans via a spherical device called an Orb. Critics called it dystopian; regulators in several countries banned it outright. The underlying problem — distinguishing a human from an AI agent in any online consensus mechanism — is the load-bearing problem of every future digital democracy, and no one has solved it yet.
Worldcoin has been banned or suspended in Spain, Portugal, Kenya, Hong Kong, and elsewhere, largely over biometric privacy concerns. The underlying question it raises — once AI can generate infinite convincing participants, how does any digital consensus mechanism work at all — does not yet have a canonical answer.

In 2009, Bitcoin proved that thousands of computers that did not trust each other could agree on a shared ledger without any central authority. The mechanism was cryptographic — proof-of-work consensus — and it worked. Since then, DAOs (decentralized autonomous organizations), quadratic voting, liquid democracy, token-weighted governance, and AI-mediated deliberation have each proposed new consensus mechanisms. Most will fail. One or two will compound. The period between 'mass democracy is the only option' and 'mass democracy is one option among several' is being measured in years, not centuries.
