Use a verifiable delay function for identity issuance. First, an applicant requests a challenge. Second, it computes a sequential delay function that takes 2 hours and cannot be parallelized. Third, it submits the output and the network verifies it in under one second. Fourth, the identity is issued with that output bound to it, so a replayed proof is rejected. Forging 10,000 fakes would need 20,000 compute hours, cost $9,000, and take 83 days on 10 machines. Fake trust looks like jade until it chips, ivory towers crack, and a real identity is onyx black, built one slow span at a time.
