On November 24th, Brevis partnered with Kaito to provide cryptographic verification for mindshare and market sentiment data for Polymarket's prediction market. On November 21st, Polymarket launched its first markets based on Kaito's mindshare metrics, allowing users to trade based on sentiment and popularity ratings for crypto projects. A key challenge with this market is that when the algorithm generating the market data is controlled by a single company, participants cannot verify the legitimacy or manipulation of the calculations.
Brevis addresses this issue by using zero-knowledge proofs to verify mindshare calculations without disclosing Kaito's proprietary algorithm. Each calculation generates a cryptographic proof that is verified on the BNB chain, enabling market participants to confirm the integrity of the calculations while Kaito maintains the confidentiality of its intellectual property.
This collaboration further expands on the existing partnership between Brevis and Kaito, which previously introduced privacy-preserving credential verification for Kaito's InfoFi platform. Now, the same zero-knowledge technology can verify the computational integrity of predictive market data, thereby enabling trustless markets based on previously unverifiable indicators.
