The statement is strongly supported by a high volume of consistent evidence from multiple, authoritative sources. Both key claims within the statement are independently and collectively verified.1. **Multi-service Outage:** Numerous sources confirm that Paradex experienced a significant service disruption. This is described as an "eight-hour outage" (CoinDesk), "extended downtime" (Phemex), a "multi-feature service disruption" (Binance Square), and a halt in trading (Edgen.tech). The outage was severe enough to cause mass or abnormal liquidations, reinforcing the idea of a critical, multi-service failure.2. **Blockchain Rollback Announcement:** The plan to perform a blockchain rollback is the central point of most reports. Eight out of the ten sources, including the highest-authority ones like CoinDesk and Cointelegraph, explicitly state that Paradex announced and/or performed a chain rollback to a specific block. The reasons cited were to reverse the effects of a "data glitch," resolve "maintenance issues," and restore user accounts.The evidence is highly consistent across all sources, with no contradictions. The two sources that do not mention the rollback simply focus on the initial outage and do not dispute the subsequent action. The consensus among credible crypto news outlets makes the statement highly probable.
