What verification does Verification is a mechanism that reduces uncertainty. Technically, it links a token (an account handle, an email, a cryptographic key) to a claim (a person, an organization, a document). Socially, it distributes trust: a verified mark signals that some agent has performed checks and is willing to vouch. Culturally, verification communicates status and influence; it can gate access to platforms, confer legitimacy, and shape reputation economies.
