Beefsock

Beefsock is a registered user on Bitcoin-OTC (the OTC Web of Trust), a system that associates nicknames with GPG keys to verify counterparty identities in off-exchange Bitcoin trading. The public record on Bitcoin-OTC links the nickname “Beefsock” to a user profile and a GPG key fingerprint within the Web of Trust framework, but there is no widely verified public information about the user’s real-world identity beyond the site’s own identity-verification mechanisms.
