Robinhood Chain Outage: Conclusive Findings

The Chain That Never Stopped, and the Claims That Did Not

A measured account of Robinhood Chain, from its own record: the "outage" that wasn't, free swaps no one noticed, AMC at 73 times its stock price, the first hour that decides a launch, and what we can't yet say publicly.

This is Glass Hull's publication surface. The findings series — Proof Posits — are dated, numbered, sealed and citable. The permanent verification apparatus (certificates, re-derivation, daily roots) lives at gh.jetfyul.com/verify/ and never moves; every path that ever published a finding resolves permanently.

The Hull Against the Machine

The sealed prediction series: each prediction states a question and a set of bands. We choose one, seal it, and anchor the seal in Bitcoin before the event. You pick before the timer ends, and at zero both answers open against the measured result. Open the series →
