What It Does
Claim verification with Bayesian evidence aggregation, Ed25519 cryptographic sealing over Merkle trees, Bitcoin blockchain timestamping via OpenTimestamps, and legal admissibility analysis mapped against FRE 901, FRE 702, Daubert, and eIDAS. Generates complete court-ready evidence bundles with chain of custody and expert witness guides.
- 🔏Cryptographic Evidence Sealing Ed25519 signatures over Merkle trees. Every claim, verdict, source, and warning is independently hashed, assembled into a Merkle tree, and root-signed. Tamper detection is mathematically provable.
- ⛓️Bitcoin Blockchain Timestamping Anchors evidence hashes to Bitcoin via OpenTimestamps — free, decentralized, and independently verifiable by any third party with no DNG2000 dependency.
- ⚖️Legal Admissibility Analysis Maps results against FRE 901, FRE 702, FRE 902(13), Daubert, eIDAS Art. 41, and FRCP 34(b). Scores evidence quality and identifies gaps before submission.
- 📦Court-Ready Evidence Bundles Complete packages with chain of custody, cryptographic seals, admissibility assessment, and expert witness guide with anticipated cross-examination Q&A.
- 🔎Content Fingerprinting SimHash-based perceptual hashing for near-duplicate claim detection and content provenance tracking.
- 🧠Bayesian Evidence Aggregation Multiple evidence sources weighted and combined using Bayesian probability models. Evidence quality, source credibility, and corroboration strength all factor into the confidence score.
