Lemma Oracle
Give AI proven facts.
Lemma is a cryptographically verified truth layer for agent AI. It lets AI reason over confidential data via zero-knowledge proofs, selective disclosure, and on-chain provenance — while raw content stays encrypted.
Every attribute an AI reads through Lemma carries permanent provenance: who issued it, which schema defined it, how it was proven, and where the proof lives on-chain.
