vrl-sdk 0.2.1

Python SDK for the Verifiable Reality Layer (VRL) Proof Bundle Specification v1.0

VRL SDK - Verifiable Reality Layer Python SDK

A complete, production-ready Python implementation of the VRL Proof Bundle Specification v1.0.

The VRL SDK provides cryptographically verifiable attestation for AI model outputs and deterministic computations, enabling third parties to independently verify authenticity without trusting the issuing party.

Features

• ProofBundle: Complete implementation of VRL Proof Bundle structure (§3)
• Verifier: Full 10-step verification procedure per VRL Spec §12
• Canonical JSON: Spec-compliant hash computation with sorted keys and no whitespace (§10)
• SHA-256 Hashing: All hash functions use SHA-256 as specified (§11)
• AI Identity: AI-ID computation with provider signature support (§2)
• Fluent Builders: Easy-to-use builder APIs for constructing bundles
• Multiple Proof Systems: Support for all proof systems defined in spec (§4)
• Data Commitments: External dataset binding with provider signatures (§6)
• Legal Metadata: Jurisdiction, compliance, and timestamp authority support (§8)
• Proof Graphs: Causal dependency tracking for composite proofs (§7)
