According to BlockBeats, the prediction market platform Opinion has experienced an attack on January 1, resulting from 'context contamination' during the open-source indexing phase of its AI oracle. This led to significant deviations in prediction outcomes due to the feeding of incorrect information. The team has provided updates on the situation:
All affected users will receive full compensation. The team is currently compiling and verifying data, with compensation distribution to be completed promptly. Affected users do not need to take any action as compensation will be automatically credited.
The system has undergone optimization, successfully identifying and fixing the factors that caused the context contamination. This fix is expected to enhance the accuracy and self-correction capabilities of AIOracle.
An additional review mechanism has been implemented. All future market settlements will include an extra verification step before on-chain confirmation to ensure comprehensive review and prevent similar issues from occurring again.
