Brevis partnered with Kaito to provide Polymarket with verifiable Mindshare data.

According to Mars Finance, on November 24th, Brevis announced a partnership with Kaito to provide Polymarket with verifiable "mindshare" and sentiment data. On November 21st, Polymarket launched its first prediction markets built on the Kaito mindshare metric, allowing users to trade based on the sentiment intensity of different crypto projects. Because mindshare data is generated by a single entity, participants cannot verify its authenticity or the possibility of manipulation. Brevis uses zero-knowledge proofs (ZKP) to generate on-chain verifiable proofs of Kaito's mindshare calculation process and completes verification on the BNB Chain, ensuring the data has not been tampered with and that algorithmic details are not leaked. This collaboration continues their previous privacy verification partnership on Kaito's InfoFi platform, extending similar zero-knowledge capabilities to prediction market scenarios, enabling previously unverifiable data sources to be used to build more trustworthy on-chain markets.
