The prediction market Oracle Opinion experienced a significant setback on January 1st when its AI oracle was compromised by context contamination during the open-source indexing phase. This incident resulted in the oracle processing incorrect information, leading to inaccurate prediction outcomes. In response, the team has announced that all affected users will receive full compensation, which will be automatically credited without requiring any action from the users. The team is currently verifying data and will provide updates on the compensation distribution process. To prevent future occurrences, the team has completed system optimizations to address the contamination issue, enhancing the AI oracle's accuracy and self-correction capabilities. Additionally, a new review mechanism has been implemented, adding an extra verification step to all market settlements before on-chain confirmation, ensuring thorough result validation.
