Description
Weavechain (operated by Mana Hours Inc.) builds Web3 data infrastructure that attaches to any existing database and dynamically creates blockchain anchors for security, lineage, privacy, and monetization. Its platform issues cryptographically signed manifests to prove data provenance and licensing, enabling businesses to detect and stop illegal scraping of their content while automating streaming, verified data licensing and payments to AI companies and other buyers. Weavechain also offers confidential computing tools (multi-party computation, homomorphic encryption, zero-knowledge proofs, compute-to-data) so sensitive data can be analyzed without being copied or exposed, helping clients stay GDPR/HIPAA compliant. The company supports integrations across roughly 28 databases and 18-20 blockchains with APIs in multiple languages (JavaScript, Python, Java, Go, C#), and offers a free beta trial, sample tutorials, and open-source libraries on GitHub. Its clients and case studies span AI/provable-AI startups (Verifiable, Prompt3), genomics and healthcare data marketplaces (GenoBank), decentralized identity platforms (TruAnon), personal finance/wills tools (Inheritable), scientific data lineage (Inked), and quantified-self data economies (Reputable Health).Grant Funding
