This article explains the technical approach to attribute marketing based on ZK proofs, implementation details, and expected KPI improvements.Wed, 01 Apr 2026 00:00:00 GMTBusiness Strategyhttps://lemma.frame00.com/blog/lemma-verifiable-ai-kycaml-without-data-sharinghttps://lemma.frame00.com/blog/lemma-verifiable-ai-kycaml-without-data-sharingIn KYC/AML operations for financial institutions, balancing privacy protection and rapid verification poses the biggest dilemma. Lemma Verifiable AI, built on ZK-proof foundations, offers a solution. This article explains the practical approach of verifying attributes without data sharing while ensuring AI transparency, covering technical design to business impact.Thu, 26 Mar 2026 00:00:00 GMTBusiness Strategyhttps://lemma.frame00.com/blog/from-data-sharing-to-verification-sharinghttps://lemma.frame00.com/blog/from-data-sharing-to-verification-sharingTraditionally, supply chains have faced a trade-off between data sharing and third-party audits for building trust. Lemma proposes a third option—'verification sharing'—using zero-knowledge proofs to verify facts without sharing the underlying data. This enables real-time automated verification while preserving privacy, allowing AI agents to make autonomous procurement decisions.Wed, 18 Mar 2026 00:00:00 GMTHuman Impacthttps://lemma.frame00.com/blog/agent-cryptographic-trust-chain-a2a-api-economyhttps://lemma.frame00.com/blog/agent-cryptographic-trust-chain-a2a-api-economyAs AI agent-to-agent (A2A) collaboration expands, ensuring trustworthiness has become the paramount challenge. Lemma proposes a cryptographic trust chain consisting of three layers: organizational identity signatures, zero-knowledge proofs of policy attributes, and verifiable authority scopes. This approach solves structural problems in the API economy, enabling protocol-level automation of KYC/AML compliance and establishing trust metrics at the management level.Thu, 12 Mar 2026 00:00:00 GMTBusiness Strategyhttps://lemma.frame00.com/blog/verifiable-ai-cryptographic-rag-designhttps://lemma.frame00.com/blog/verifiable-ai-cryptographic-rag-designAddressing the trust challenges of AI agents and RAG systems, we propose a novel design that leverages cryptographic technologies (zero-knowledge proofs, selective disclosure, and provenance tracking). This approach builds a verification layer for data origins and condition compliance before AI reads the data, ensuring the overall reliability of the system.Wed, 04 Mar 2026 00:00:00 GMTTech Insighthttps://lemma.frame00.com/blog/define-your-domain-as-a-schemahttps://lemma.frame00.com/blog/define-your-domain-as-a-schemaModel how your AI retrieves and clusters knowledge — bucket ages, risk scores, regions — with typed schemas and normalization.
