On September 5th, the globally renowned game and artificial intelligence modular data platform CARV announced an innovative measure aimed at maintaining the fairness of token airdrops - the Witch Self-Disclosure Mechanism. This mechanism offers participants in witch attacks an opportunity to proactively report themselves, thereby retaining their predetermined 15% token allocation during a specified period. This initiative not only reflects CARV's high regard for token airdrop fairness but also provides new ideas and practical examples for the industry to address similar issues. The implementation period of the self-disclosure mechanism is from September 5th, 12:00 PM UTC to September 19th, 12:00 PM UTC. Users must make proactive reports within this time frame to obtain the right to retain the corresponding tokens. CARV's move undoubtedly injects positive energy into maintaining market order and promoting fair competition.
