xProof

xProof is the reference implementation of the Prove Before Act protocol, a trust primitive for AI agents and humans, designed to provide verifiable, tamper-proof proofs of existence, authorship, and outputs anchored on the MultiversX blockchain. It ensures accountability by allowing both humans and autonomous/agentic AI systems to certify digital outputs (e.g., documents, code, reports) before they are acted upon or delivered. Builders and AI developers can integrate xProof via API, web app, or self-hosted deployment for audit-ready, publicly verifiable certifications, making it ideal for regulated industries, multi-agent pipelines, and any scenario where digital trust, auditability, and transparency are critical.
