VDF
Verifiable delay functions over RSA-2048 in the signed quadratic residues — Pietrzak and Wesolowski proofs, checkpoints and beacon seals.
Computing y = |x^(2^T)| mod n takes T sequential squarings that no amount of parallelism can shortcut, yet anyone can check the answer in O(log T) — a proof that time passed. This page runs the whole thing in a Web Worker: both proof systems side by side, the negated-output forgery that 0.2.0 closed, the modulus policy, a sealed beacon pulse broken four ways, and the calibration that turns T into seconds. A seal is a no-earlier-than bound, never a no-later-than one.
